Organic Medicinal and Aromatic Plants: Consumption Profile of a Portuguese Consumer Sample.

The production and consumption of organic products have been increasing in Portugal, as well as in the European Union as a whole. The main objective of this work is to understand the consumption habits of organic medicinal and aromatic plants (OMAPs) among Portuguese adults. An online questionnaire was distributed using social networks, resulting in the collection and statistical analysis of 300 responses. Of the participants who reported consuming OMAPs, 44.3% showed a daily consumption pattern. The most frequently mentioned OMAPs for fresh consumption were parsley (Petrosselinum crispum L., 92%), garlic (Allium sativum L., 84.1%), and coriander (Coriandrum sativum L., 78.1%). The most commonly mentioned OMAP for consumption as dried plants were oregano (Origanum vulgare L., 74.6%), lemon balm (Melissa officinalis L., 49.2%), and lemon verbena (Aloysia citrodora L., 46.8%). The main reasons cited for using OMAPs were their benefits to health (58.7% of participants), benefits to the environment (33.2%), and reduced salt consumption (29.5%). Among these, the main health benefits mentioned included anti-inflammatory properties (45.0%), prevention of cardiovascular diseases (41.6%), and prevention of high cholesterol (39.9%). Furthermore, 82.5% of respondents considered themselves sufficiently, well, or excellently informed about the nutritional properties of OMAPs. This research initiates a discussion about whether profiling OMAP consumption habits can serve as a valuable tool for promoting organic farming in Portugal, increasing OMAP production and consumption, and strengthening the connection between these products and potential positive human health effects.

Effect of Light Intensity on Photosynthesis in Aquatic Plants in Australia

Purpose: The aim of the study was to investigate the Effect of Light Intensity on Photosynthesis in Aquatic Plants in Australia.
 Methodology: The study adopted a desktop methodology. Desk research refers to secondary data or that which can be collected without fieldwork. Desk research is basically involved in collecting data from existing resources hence it is often considered a low cost technique as compared to field research, as the main cost is involved in executive’s time, telephone charges and directories. Thus, the study relied on already published studies, reports and statistics. This secondary data was easily accessed through the online journals and library
 Findings: In the study examining the impact of light intensity on photosynthesis in Australian aquatic plants, key findings emerged. It was evident that light intensity played a crucial role, with higher light levels in shallower waters leading to increased photosynthesis rates. This underscored the significance of light as a primary determinant of photosynthesis in these ecosystems. Additionally, the study highlighted the impressive adaptability of Australian aquatic plants, some of which employed unique photo protective mechanisms to prevent photo inhibition under varying light conditions.
 Unique Contribution to Theory, Practice and Policy: Theory of Liebig's Law of the Minimum, Theory of The Beer-Lambert Law and Optimal Foraging Theory may be used to anchor future studies on the Effect of Light Intensity on Photosynthesis in Aquatic Plants in Australia. Develop practical guidelines for growers to optimize light conditions for maximum photosynthetic efficiency. Advocate for policies that recognize the significance of aquatic plants in maintaining healthy aquatic ecosystems. Promote the conservation and restoration of natural habitats for aquatic plants, especially in areas threatened by pollution or habitat destruction.

Ruderal vegetation (Ruderalophyton) of transformed habitats of the Rostov-on-Don urban ecosystem, Russia

Aim. To investigate the features of the abiotic (soils) and biotic (flora and vegetation) components of ruderal communities (Ruderalophyton) of the urban ecosystem in the conditions of the Rostov agglomeration.Material and Methods. The morphoecological analysis of the flora (144 species of vascular plants) was shown. Data were obtained of the characteristic growth features of roadside communities of the Southern Federal University Botanical Garden (floristic diversity of 53 species) and of ruderal communities of new residential building plots in the peripheral part of the city and abandoned houses in the central part of the city.Results. Abiotic conditions for the habitats of ruderal plants are no longer natural because the local Chernozem root‐inhabited and humusaccumulative surface horizons have been almost completely stripped away. At the same time, cenotically the communities are multicomponent and floristically saturated with high projective coverage. During the process of anthropogenic vegetation evolution, a new type of cenosis has formed, which is adapted in ecological succession processes to all components of the urban ecosystem.Conclusion. The ruderal vegetation of the Rostov agglomeration is particularly resistant. It develops urban horizons, which are characterized by a high proportion of anthropogenic inclusions; household, and industrial waste, which is often contaminated with organic and inorganic pollutants. Plant communities developing on such substrates are multicomponent, floristically saturated and have formed a high degree of projective cover.

Public perception of the performance of Czech forest ecosystem services

AbstractIn recent years, there has been growing interest in public valuation for forest ecosystem services in policymaking. This paper investigates the public’s perception of the Czech forest ecosystem services, i.e., provisioning, regulating and cultural services, with associated factors (changes in forest cover, production, and respondents’ characteristics). The performance perception of forest ecosystem services was gathered from a nationwide survey in 2020. The Coordination of Information on the Environment Land Cover information in 2000 and 2018 was used for observation of forest cover changes. Coniferous and non-coniferous (broadleaved) roundwood, mushroom, and bilberry production data from the observed years were acquired from the Czech Statistical Office and the Ministry of Agriculture’s annual nationwide surveys. The Bohemia vs. Moravia study areas were also statistically compared. Predictor analysis of the high score of performance perception from individual and cluster forest ecosystems was also performed to answer the research objectives. The group of forest provisioning services received high scores in public evaluation (from 3.9 to 4.2), followed by regulating services (mean range: 3.7–4.1). The highest score was found in forest as a natural habitat for wild animals and plants (mean: 4.6). However, the lowest value was the esthetic value (mean: 2.3). Both are categorized as forest cultural services. The broadleaved and mixed forest areas in 2018 were significantly higher than in 2000, especially in Bohemia. Meanwhile, the total coniferous forested region in 2018 declined substantially compared to 2000 (p = 0.030), especially in Moravian areas. A significantly higher total production of the coniferous and broadleaved roundwood removals in 2018 than in 2000 was reported, in contrast to a marked decrease in collected mushrooms and bilberries. The high score of performance perception of forests as the wood provisioning service was positively and significantly associated with the changes in broadleaved roundwood removals. Older-age and female respondents were the primary predictors of the studied cluster and individual forest ecosystem services. The findings indicate that the social value of the individual forest provisioning services supports the implementation of multi-species and multi-purpose forests; hence, it encourages the implementation of the current Czech forest policy.

Microhymenoptera in roadside verges and the potential of arthropod‐friendly mowing for their preservation

AbstractThe worldwide decline of insects is one of the major challenges for humankind. One of its main drivers is intensive farming, which reduces habitats and food resources for insect populations and causes direct mortality by pesticides. In addition, mowing of grassland poses another threat to insects, especially when it is done frequently, such as in roadside verges. Roadside verges comprise large areas worldwide and can serve as habitats for animals and plants and as corridors to connect populations when they are maintained ecologically, for example when mowing is done arthropod‐friendly and with low frequency. Microhymenoptera are highly diverse, mostly show a parasitoid lifestyle and occur in large numbers in meadows and grasslands. Although they have an important ecological function in regulating their arthropod host populations, they were mostly neglected in studies on the influence of mowing on insects. Therefore, we assessed which families of microhymenoptera occur in roadside verges and meadows, examined if they are affected by the mowing process with a conventional mulching mower, and studied which groups benefit from arthropod‐friendly mowing, using the mowing head Eco 1200 plus from MULAG, and a flushing bar made of track tarpaulin. In our experimental grassland plots, we found specimens of 18 families from the six microhymenoptera superfamilies Chalcidoidea, Ceraphronoidea, Diaprioidea, Ichneumonoidea, Platygastroidea and Proctotrupoidea. Mowing with a conventional mulching mower caused a significant loss of up to 64% for parasitoid Hymenoptera. The Eco 1200 plus showed an arthropod‐friendly effect only on the number of individuals of Chalcidoidea, saving 38% of individuals compared with the conventional mower. The flushing bar showed a significant effect on total number of individuals with a reduction only on Chalcidoidea and a tendency for Ichneumonoidea with 30% and 47%, respectively. Our study demonstrates the detrimental effect of mowing with a conventional mulching mower on microhymenoptera and shows that this effect can be partly reversed for Chalcidoidea and Ichneumonoidea through the arthropod‐friendly mower and a flushing bar. Our study highlights the importance to consider microhymenoptera in the context of insect decline.

Pollen sources of Asian honeybee (Apis cerana Fabricius) in Paschim Medinipur district of West Bengal, India

The Asian honeybee (Apis cerana) occurs across the south, southeast and east Asia. The species is utilised in apicultural practices. But the available documents about their floral resources, especially pollen sources, are limited. However, it is a mandatory requirement in a sustainable honeybee management programme. In the present study, we conducted palynological analyses of pollen loads and field surveys to determine pollen sources for the honeybees in West Bengal, India. The honeybee species is regarded as a generalist forager with significant floral constancy supported by homogenous pollen loads with diverse pollen types (here 58). Important pollen-contributed plants were Acacia auriculiformis, Brassica juncea, Cocos nucifera, Eucalyptus sp., Neolamarckia cadamba, Peltophorum pterocarpum, Sesamum indicum and Tridax procumbens. In the semi-urban area of Midnapore town, honeybees mainly depend on planted trees and weeds for pollen sources. While in rural agricultural belts, they also visited wild trees and several cultivated crops. The bee-visited plants are diverse types regarding plant habits, flowering phenology and floral characteristics. These data will be helpful in the management of Asian honeybees, providing pollination services to cultivated crops and thereby enhancing crop yield.

Plant species identity and mycorrhizal type explain the root-associated fungal pathogen community assembly of seedlings based on functional traits in a subtropical forest.

As a crucial factor in determining ecosystem functioning, interaction between plants and soil-borne fungal pathogens deserves considerable attention. However, little attention has been paid into the determinants of root-associated fungal pathogens in subtropical seedlings, especially the influence of different mycorrhizal plants. Using high-throughput sequencing techniques, we analyzed the root-associated fungal pathogen community for 19 subtropical forest species, including 10 ectomycorrhizal plants and 9 arbuscular mycorrhizal plants. We identified the roles of different factors in determining the root-associated fungal pathogen community. Further, we identified the community assembly process at species and mycorrhizal level and managed to reveal the drivers underlying the community assembly. We found that plant species identity, plant habitat, and plant mycorrhizal type accounted for the variations in fungal pathogen community composition, with species identity and mycorrhizal type showing dominant effects. The relative importance of different community assembly processes, mainly, homogeneous selection and drift, varied with plant species identity. Interestingly, functional traits associated with acquisitive resource-use strategy tended to promote the relative importance of homogeneous selection, while traits associated with conservative resource-use strategy showed converse effect. Drift showed the opposite relationships with functional traits compared with homogeneous selection. Notably, the relative importance of different community assembly processes was not structured by plant phylogeny. Drift was stronger in the pathogen community for ectomycorrhizal plants with more conservative traits, suggesting the predominant role of stochastic gain and loss in the community assembly. Our work demonstrates the determinants of root-associated fungal pathogens, addressing the important roles of plant species identity and plant mycorrhizal type. Furthermore, we explored the community assembly mechanisms of root-associated pathogens and stressed the determinant roles of functional traits, especially leaf phosphorus content (LP), root nitrogen content (RN) and root tissue density (RTD), at species and mycorrhizal type levels, offering new perspectives on the microbial dynamics underlying ecosystem functioning.

De-novo whole genome assembly of the orange jewelweed, Impatiens capensis Meerb. (Balsaminaceae) using nanopore long-read sequencing.

The plant family Balsaminaceae comprises only two genera, and they are a study in contrasts. While Impatiens is an impressively prolific genus, with over 1,000 species and more being discovered each year, its sister genus, Hydrocera, has one solitary species, H. triflora. The two genera also differ in geographic distribution and habitat type (Impatiens species are widely distributed in much of the Old World and N. America, while H. triflora is confined to wetlands specific to S. India, Sri Lanka, and SE Asia). Other contrasting features include plant habit, habitat, floral architecture, mode of seed dispersal, and a host of other traits. The family Balsaminaceae is therefore an excellent model for studying speciation and character evolution as well as understanding the proximal and evolutionary forces that have driven the two genera to adopt such contrasting evolutionary paths. Various species of the Impatiens genus are also commercially important in the ornamental flower industry and as sources of phytochemicals that are of medicinal and other commercial value. As a preliminary step towards studying the genomic basis of the contrasting features of the two genera, we have sequenced and assembled, de novo, the genome of an iconic Impatiens species from N. America, namely I. capensis, and report our findings here.

FOREST PROTECTION EFFORTS AGAINST CONVERTING FOREST FUNCTIONS TO PALM OIL PLANTATIONS

The conversion of forest functions to oil palm plantations has often been carried out in Indonesia. Many factors motivate communities, individuals, and companies to do this. One of them is the economic factor. Investment in oil palm plantations is considered a promising investment and generates many profits. However, individuals or companies often need to pay more attention to ecological aspects and the impacts of the forest function's conversion. The consequences resulting from the transformation of forest functions will affect the environment in the short and long term. Forests that have many benefits and uses not only for humans but also for the habitat of animals and plants in them must be protected and preserved. The increasingly widespread conversion of forest functions results from fulfilling human desires and harming other living things, so the government is obliged to make an effort through prevention and mitigation so that the existence of forests and their sustainability are maintained and can continue to bring many benefits to living things.

Analysis of the Structural Organization and Expression of the Vrn-D1 Gene Controlling Growth Habit (Spring vs. Winter) in Aegilops tauschii Coss.

The duration of the vegetative period is an important agronomic characteristic of cereal crops. It is mainly influenced by the Vrn (response to vernalization) and Ppd (response to photoperiod) genes. In this work, we searched for alleles of several known genes of these two systems of response to external conditions in 15 accessions of Aegilops tauschii Coss. (syn. Ae. squarrosa L.), with the aim of studying the impact these alleles have on the vegetative period duration and growth habit. As a result, three allelic variants have been found for the Vrn-D1 gene: (i) one intact (winter type), (ii) one with a 5437 bp deletion in the first intron and (iii) one previously undescribed allele with a 3273 bp deletion in the first intron. It has been shown that the spring growth habit of Ae. tauschii can be developed due to the presence of a new allele of the Vrn-D1 gene. Significant differences in expression levels between the new allelic variant of the Vrn-D1 gene and the intact allele vrn-D1 were confirmed by qPCR. The new allele can be introgressed into common wheat to enhance the biodiversity of the spring growth habit and vegetative period duration of plants.

Prediction of suitable planting areas of Rubia cordifolia in China based on a species distribution model and analysis of specific secondary metabolites

The expansion or reduction of suitable habitats for medicinal plants may result from climate change. There are few reports on the distribution of suitable habitats or potential origins of Rubia cordifolia L., a relatively common herb. However, due to its important pharmacological properties, it is essential that high-quality R. cordifolia can be provided in the future. Therefore, this study combined the biomod2 ensemble platform and the secondary metabolites of R. cordifolia roots to predict its suitable habitats and potential planting areas. Root samples and occurrence data were gathered through fieldwork and public databases. Ultra high-performance liquid chromatography was used to measure the concentrations of two important secondary metabolites in the roots. According to the findings, appropriate habitats covering an area of 2,706,795 km2 were found in various regions, primarily in the eastern and southern parts of China. Under future climate scenarios, suitable habitats shrank inward or expanded outward along the current suitable habitats. Additionally, purpurin was extensively spread, and mollugin was narrowly distributed within the suitable habitats, resulting in dispersed and restricted potential planting areas (893,116 km2). In addition, the precipitation of the wettest month is crucial for distributing suitable habitats and the synthesis of two secondary metabolites. However, there is a risk of losing suitable planting areas for R. cordifolia due to future climate scenarios. Therefore, effective conservation and management measures are urgently needed. In conclusion, the findings of this study may serve as a guide for choosing appropriate planting areas for R. cordifolia.

Plant remains preserved in products of metal corrosion: source of evidence on ancient plant materials and environment from burial contexts

By-products of metal corrosion, when coming into contact with organic matter, have the capacity to preserve it from decay. A pilot study was conducted aiming to explore the potential and limitations of plant remains preserved in by-products of metal corrosion for archaeobotanical research. The organic remains considered come from the surface/immediate proximity of the metal funerary artefacts of two ancient cemeteries—Varna and Messambria, Eastern Bulgaria. Metal corrosion by-products were observed and sampled, under a low magnification stereo microscope. Subsequently, the plant macrofossils recognised were analysed under reflected light and a scanning electron microscope (SEM). Additionally, pollen was extracted from the metal corrosion by-products, using standard acetolysis. The analyses from the graves of both cemeteries allowed identification of textiles and plant fibres, as well as wood (Cornus sp., Pinus sp., Viburnum sp.). At Varna cemetery epidermis fragments of Juncus sp. were recognized, while at Messambria necropolis fruits of almond were found. The pollen analysis from Varna points to use of flowers in the ritual (Daphne tetrads were recorded) and shows a notably open landscape with 77% non-arboreal pollen (NAP). The palynological analysis from the Messambria necropolis revealed the use of flowers in the burial ritual indicated by clusters of Vitis, Cistus and Rosaceae pollen. The surrounding vegetation was dominated by open oak woodland and open habitats (43% NAP) with a strong presence of anthropogenic indicators. The outcome of the study proved to be promising for reconstructing details of the burial rituals including associated plant materials, as well as the surrounding plant habitats during the functioning of the cemeteries.

Nature in the concrete jungle: valuing urban ecosystem services in Costa Rica

AbstractUrban green spaces are primarily recognized for their ability to provide opportunities for recreational activities. However, these spaces also offer a broader range of ecosystem services and benefits, which are often overlooked by city inhabitants and the government. This paper utilizes choice experiments to estimate the benefits derived from ecosystem services provided by undeveloped natural areas and urban parks in San José, Costa Rica. We evaluate three ecosystem services provided by undeveloped natural areas, namely habitats for animals and plants, hydrological control, and recreation. Additionally, we estimate the benefits derived from the restoration and construction of three types of urban parks: neighborhood, metropolitan, and central district parks. The results demonstrate that individuals place significant value on the restoration of undeveloped natural areas and urban parks. The findings also indicate variations in the valuation of ecosystem services between undeveloped natural areas and different park types, as well as among households.

Distribution of Poisonous Plants in Biomes of the Southern Far East of Russia

Poisonous plants are a collective group of plants of various systematic categories that contain phytotoxins that pose a potential danger to humans and animals. A number of publications both in Russia and abroad are devoted to the problem of patterns of distribution of plants hazardous to human health in connection with environmental factors. This work is a continuation of research into the spread of plants dangerous to humans in Russia. The aim of this work is ecological and geographical analysis of poisonous plants distribution in biomes of the Far East in Russia. Resulted from the research work on the territory of the far-eastern biomes of Russia we revealed 87 the most toxic vascular plant species that belong to 21 plant families. Some of the most poisonous plants of the Russian flora are plants of the genus Aconitum, of the family (Ranunculaceae). About 70 species of this genus grow in Russia, of which 40 are found only in the Far East, since this territory is considered the center of botanical diversity of the genus in question. The cartographical analysis showed that the highest number of poisonous plant species could be found in the south-east regions – in Primorye, the basin of Ussuri river, in the lower and middle course of the river Amur. Based on a map of Russian biomes, optimal habitats for poisonous plants were identified. Maximum number of Aconitum species, as the most poisonous genus of Russian flora, is in the mountain biomes and in the plain forest-steppe biomes in the Amur basin. The types of ecosystems with the maximum abundance and diversity of poisonous plants have been identified. The species richness distribution shows the concentration of poisonous plant species in small mountain biomes and in arid-like biomes. Correlation analysis of relationships between the number of plant species and climatic factors revealed the significant closeness of the correlation with the average annual air temperature (0,66). Maximum correlation closeness appeared to be between number of poisonous plant species per 10 000 km2 and total number of vascular plants per 10 000 km2 (0,81).

Determinates of bryophyte diversity, in comparison with vascular plant diversity, in paddy fields

Introduction Paddy-field landscapes play an important role in conservation of plant diversity. However, in only a few studies has bryophyte diversity been investigated in these landscapes. Therefore, we examined the characteristics and factors that determine bryophyte diversity in paddy fields. Methods Three approaches were used in this study: plant taxa, life form, and habitat type. Our aim in using the plant-taxa approach was to reveal differences between bryophytes and vascular plants in terms of landscape elements that are significant for species richness. The life-form and habitat-type approaches were used to elucidate how landscape elements determined bryophyte diversity. Generalised linear models and non-metric multidimensional scaling were used for these analyses. Results and discussion The landscape elements influencing species richness differed between vascular plants and bryophytes. Specifically, the forest area emerged as a crucial factor for bryophyte richness. Moreover, the species composition of bryophytes was determined by the forest area, influencing the prevalence of hydrophilic life forms and presence of forest-associated bryophyte species. These results can be attributed to two key functions of forest areas: supplying forest species to adjacent paddy fields, and alleviating heat and drought stress. Conclusions Bryophyte diversity in paddy fields was influenced more strongly by the surrounding forest areas than by the vascular plant diversity, owing to the vulnerability of bryophytes to drought stress. These results highlight the importance of forest–paddy mosaics for conservation of bryophyte diversity in paddy fields. Furthermore, the species composition results suggest that paddy fields can serve as suitable habitats for flood-plain bryophytes.

Role of soil parameters in forest clove (Syzygium obtusifolium) habitat and their effects on phenology and production

Abstract. Kamsurya MY, Bontari S, Kamaruddin, Hulopi F, Lahabi M, Djumati JL. 2023. Role of soil parameters in forest clove (Syzygium obtusifolium) habitat and their effects on phenology and production. Biodiversitas 24: 4910-4918. Forest cloves (Syzygium obtusifolium L.) are a type of non-aromatic clove that originally grew wild and are now starting to be cultivated. This study aimed to examine role of soil chemical and physical parameters in clove plant habitat and their influence on flowering phenology and production. The experiment was carried out on the island of Ambon Maluku, for a duration of 17 months from January 2020 - May 2021. A survey was conducted on forest clove plant cultivated by farmers aged between 10-15, and five observation locations were selected using the purposive sampling method. Soil analysis was performed at the Laboratory of Soil Science, Faculty of Agriculture, University of Hasanuddin Makassar, while observational data were analyzed using principal component regression analysis (PCRA). The results showed that soil chemical parameters contributed 14.89% to forest clove plant habitat, with the N and Ca content providing the highest contribution of 3.49% and 3.26% respectively. The contribution of physical parameters amounted to 8.09%, with sand particles exhibiting the highest value of 2.43%. Furthermore, PCRA results found that soil chemical parameters influenced the phenology of forest clove flowering by 21.8%. The relationship between the independent variables (X1 to X5) and flowering phenology (Y) had a correlation (R) of 0.47, while the physical parameters exerted an influence reaching 79.4% with an R-value of 0.89. The average production of fresh and dry clove flowers from forest clove plant was 50.3 and 20.1 kg/plant, respectively.

Assessing Radish Health during Space Cultivation by Gene Transcription.

During the Advanced Plant Habitat experiment 2, radish plants were grown in two successive grow-outs on the International Space Station (ISS) for 27 days each. On days 10, 18, and 24, leaf punch (LP) samples were collected and frozen. At harvest, bulb tissue was sampled with oligo-dT functionalized Solid Phase Gene Extraction (SPGE) probes. The space samples were compared with samples from ground controls (GC) grown at the Kennedy Space Center (KSC) under the same conditions as on the ISS, with notably elevated CO2 (about 2500 ppm), and from lab plants grown under atmospheric CO2 but with light and temperature conditions similar to the KSC control. Genes corresponding to peroxidase (RPP), glucosinolate biosynthesis (GIS), protein binding (CBP), myrosinase (RMA), napin (RSN), and ubiquitin (UBQ) were measured by qPCR. LP from day 24 and bulb samples collected at harvest were compared with RNA-seq data from material that was harvested, frozen, and analyzed after return to Earth. The results showed stable transcription in LP samples in GC but decreasing values in ISS samples during both grow-outs, possibly indicative of stress. SPGE results were similar between GC and ISS samples. However, the RNA-seq analyses showed different transcription profiles than SPGE or LP results, possibly related to localized sampling. RNA-seq of leaf samples showed greater variety than LP data, possibly because of different sampling times. RSN and RPP showed the lowest transcription regardless of method. Temporal analyses showed relatively small changes during plant development in space and in ground controls. This is the first study that compares developmental changes in space-grown plants with ground controls based on a comparison between RNA-seq and qPCR analyses.

Stand-up paddling: A case study on the effect and impact pathway of information and appeals to reduce ecological conflicts

Water bodies form important habitats for animals and plants. At the same time, they offer special recreational benefits, through nature experiences, their scenic quality or as a basis for sport activities. However, high visitor numbers and problematic behaviour can lead to disturbances in nature. To maintain the recreational benefits of such public spaces and to protect nature, campaigns are a useful means, in addition to spatial interventions and legal regulations. This study evaluates a campaign to reduce negative effects on nature due to the increasingly popular activity of stand-up paddling. A written pre-post survey of the treatment group at Lake Greifensee was completed by the stand-up paddlers on site on tablets or location-independently on their own device. The control survey took place at Lake Lauerzersee, but mainly via various disseminators and social media in German-speaking Switzerland, starting with the pre-survey and ending with the post-survey at Lake Greifensee. The total sample comprised 334 people. To evaluate the campaign, behavioural predictors - based on the theory of planned behaviour (TPB) (Ajzen, 1991) - and self-reported behaviour of stand-up paddlers with and without exposure to the campaign were compared. Exposure to the campaign influenced the predictor “perceived control” the most; the two variables “knowledge” and “self-assessed skills” increased significantly with exposure to the campaign. The poster, which was present on site throughout the campaign, was the communication tool most perceived by stand-up paddlers. The variables that best predicted self-reported behaviour were behavioural knowledge, relevance, and self-assessed ability. The results indicate that TPB-predictors tend to be positively influenced by campaign exposure, and they point to a relationship between TPB-predictors and behaviour. However, not all components of the TPB-predictors are statistically significantly improved by campaign exposure, nor do they all significantly influence self-reported behaviour. Nonetheless, the results show that persuasive work improves self-reported ecological behaviour and largely confirm the impact path for persuasion as it has been theoretically proposed. Management implications•A combination of information and behavioural recommendations reduce conflicts between stand-up paddlers and nature. To improve all TPB-predictors, additional efforts such as persuasion on an emotion-related basis are recommended.•Due to the low level of organization of the activity and because information is rarely obtained in advance, paddlers are best informed on site or in the beginning of their activity career (e.g., when buying/renting equipment).

The Role of the Hercynian Mountains of Central Europe in Shaping Plant Migration Patterns in the Pleistocene-A Review.

The climatic changes that took place in Europe during the Quaternary period influenced plant habitats as well as their species and vegetation composition. In this article, biogeographical studies on Hercynian mountain plants that include data for the Alps, Carpathians, and European lowlands are reviewed in order to discuss the phylogeographical structure and divergence of the Hercynian populations from those in other European mountain ranges, Scandinavia, and lowlands. The analyzed studies show specific phylogeographical relations between the Hercynian mountains, Alps, Scandinavia, Carpathians, and European lowlands. The results also indicate that the genetic patterns of plant populations in the Hercynian Mountains may differ significantly in terms of origin. The main migration routes of species to the Hercynian ranges began in the Alps or Carpathians. Some species, such as Rubus chamaemorus L., Salix lapponum L., and Salix herbacea L., are glacial relics that may have arrived and settled in the Hercynian Mountains during the Ice Age and that survived in isolated habitats. The Hercynian Mountains are composed of various smaller mountain ranges and are a crossroads of migration routes from different parts of Europe; thus, intensive hybridization has occurred between the plant populations therein, which is indicated by the presence of several divergent genetic lines.

Ethnobotany and conservation applications in the Noken making by the Sougb Tribe of West Papua, Indonesia

Abstract. Saiba Y, Ungirwalu A, Murdjoko A, Brearley FQ, Peday MH, Yowei RN, Imburi CS, Runtuboi YY, Djitmau DA, Sa'diyah SH. 2023. Ethnobotany and conservation applications in the Noken making by the Sougb Tribe of West Papua, Indonesia. Biodiversitas 24: 4577-4583. Documenting local ecological knowledge is critical for understanding complex ecological-cultural interactions to protect indigenous community entities. Woven baskets known as Noken have been part of Papuan indigenous culture for centuries, yet ethnobotanical aspects of Noken making remain poorly understood. Hence, this study describes Noken-making from an ethnobotanical perspective. We acquired ethnoecological knowledge by interviewing respondents who were actively involved in the production of Noken. The results revealed that the Sougb Tribe (from South Manokwari District, West Papua, Indonesia) utilized pineapple as a primary material for weaving and other natural materials as dyes, with this process undertaken mainly by women. We also document the Sougb Tribe's adaptation and continuous interaction with their dynamic environment that has evolved during Noken's making. Moreover, the recommendation to conserve Noken preserves biocultural diversity and habitats for key plant species. Since Noken has played an essential part in shaping the Sougb Tribe's cultural identity, conserving the use of Noken will aid in preserving the habitats of plants used as materials for Noken. In the future, the provincial government should assist habitat biocultural conservation by granting tribes customary forest status to facilitate plant habitat protection in line with the sustainable development agenda of West Papua Province.
