Гербарий лишайников Института морской геологии и геофизики ДВО РАН (SAK): первые результаты инвентаризации

The organization of the lichen herbarium in the Institute of Marine Geology and Geophysics of the FEB RAS was initiated in 2014 after a number of integrated expeditions in the Sakhalin Region. The herbarium is based on the collections of Aleksandr K. Ezhkin and Vladimir V. Kaganov. A significant amount of lichen samples was collected in protected areas of the Sakhalin Region, in wild remote sites, and in areas of volcanic activity. Currently, a part of the collection (1178 samples, 307 species) is mounted and stored in the Laboratory of plant ecology and geoecology, which is about 1/8 of all herbarium material of lichens stored in the Institute of Marine Geology and Geophysics of the FEB RAS.

Evaluasi Kesesuaian Lahan Tanaman Perkebunan di Kecamatan Selo Kabupaten Boyolali

Selo District has great potential for developing plantation crops; however, the amount of production still needs to grow. The purpose of this study is to determine the soil suitability class of plantation crops (arabica coffee, tobacco, cloves, cocoa, and tea), identify limiting factors in the study area, and suggest ways to overcome them to increase land suitability classes. The study was conducted in Selo District, Boyolali Regency from November 2022 - December 2022, and the Plant Ecology Laboratory, Faculty of Animal Husbandry and Agriculture, Diponegoro University. This study used an investigative method consisting of multiple stages, laboratory data analysis, and data processing. As a result, Selo District has actual land suitability N (not suitable) for Arabica coffee and Cocoa in all area tests. In contrast, tobacco, clove, and tea had suitability classes S3 (marginally appropriate) to N (not suitable). The limiting factors that dominate are air humidity, pH, C-organic, soil texture, and slope. Efforts can be made to improve the limiting factors in the area by adding fertiliser and organic matter, feeding dolomite, and making mounds. These improvement efforts aim to increase the land suitability class for plantation crops.

Aims: To study the diversity of fungal pathogens associated with cashew mycoses in Togo.
 Study Design: This research project was initiated by the Mycology Research and Applications Unit of the Botany and Plant Ecology Laboratory (LBEV) in order to have adequate information on cashew mycoses in Togo.
 Place and Duration of Study: Laboratory of Botany and Plant Ecology (LBEV) of the University of Lome (UL) and of Crop Protection and Biosafety Laboratory of Togolese Institute of Agronomic Research (ITRA), February to August 2020.
 Methodology: A total of 148 symptomatic samples (leaves, buds, inflorescences, nuts, and apples) were collected from cashew trees in the East Mono prefecture of Togo. Malt-agar medium supplemented with chloramphenicol at 0.5 g/l was used for the isolation of fungal pathogens. The characterization of these fungal pathogens was carried out from the 7th day based on their macroscopic (texture, color, diameter of growth) and microscopic (hypha, spore, fruiting body) characters.
 Results: This study revealed the presence of five mycoses in cashew orchards in the East Mono prefecture. These are leaf anthracnose, bud’s dieback, black rust, leaf yellowing, and powdery mildew. In total, 12 fungal genera were encountered and 14 species of fungal pathogens were identified on all the samples collected: Rhizopus sp., Penicillium sp., Mucor sp., Sporotrichum sp., Fusarium nivale, Fusarium moliniforme, Fusarium moliniforme var. subglutinans, Curvularia lunata, Curvularia geneculata, Alternaria tenuissima, Alternaria brassicisola, Beltrania rhombica Penz., Thielavia coactilis Nicot, Helminthosporium avenae, Helminthosporium siccans, Phoma eupyrena, Aspergillus flavus, Aspergillus niger. 
 Conclusion: It would be of great interest to train cashew producers in the East Mono prefecture on the recognition of the symptoms of these mycoses and their management.

Emergence and Initial Development of Erythroxylum pauferrense Seedlings under Different Substrates

Erythroxylum pauferrense Plowman is an understory species native to Brazil, with great importance in the conservation of genetic resources and is used as a food source for animals in the regions where the species occurs. The species is currently listed in category EN (endangered). The objective of this work was to evaluate the effect of different substrates on the emergence and initial growth of E. pauferrense. The experiment was carried out in a protected environment, belonging to the Plant Ecology Laboratory of the Federal University of Paraíba, Areia-PB, Brazil. The substrates used were: sand; sand + vermiculite in the proportion of 1:1, 3:1 and 1:3; vegetal land; vegetal land + sand in the proportion of 1:1, 3:1 and 1:3; vegetal land + vermiculite in the proportion of 1:1, 3:1 and 1:3; vermiculite; Bioplant®; and Bioplant® + sand in a ratio of 1:1, 3:1 and 1:3. The experimental design was completely randomized, with 16 treatments (substrates) and four replications of 25 seeds.

Cultivation and Nutritional Quality of Moringa Oleifera Lam. Produced Under Different Substrates in Semi-Arid Region in Northeast Brazil

The Moringa oleifera Lam. it is a perennial, arboreal species, rapidly growing, resistant to drought and with leaves, flowers and edible fruits. With this research the objective to evaluate the effect of different substrates in the emergence and development of seedlings of Moringa. The experiment was carried out at the Plant Ecology Laboratory of the Department of Phytotechnics and Environmental Sciences, at the Center for Agricultural Sciences, at the Federal University of Paraíba. The experimental desing was completely randomized, with eight treatments T1= sand washed (control), T2= sand + coconut fiber, T3= sand + rice bark, T4= sand + bovine manure, T5= sand + pine powder, T6= sand + chicken manure, T7= sand + vegetable ash and T8= quail, with four repetitions of 25 seeds totaling 100 seeds for each treatment. The substrates were used in proportion 3:1, and these proportions were determined in terms of weight and all the sieved substrates, arranged in 6 cm x 29.5 cm x 45.5 cm trays, with an approximate capacity of 7 liters of substrate. The following parameters were evaluated: the emergence percentage, first count, emergence speed index, seedling height, plant height, root length, number of leaves, dry leaf biomass, stalk, root and total. The germination and initial development of M. oleífera seedlings were satisfactory in sand and favored when fibrous materials of vegetable origin (coconut fiber, rice bark or pine powder) or bovine manure were added to the substrate. The addition of manure sand from birds (chicken and quails) and vegetable ash did not favor the substrate for germination of Moringa oleifera Lam. seeds.

Water Logging in South-Western Coastal Region of Bangladesh: Causes and Consequences and People’s Response

Aim: Since decades, a major part of south-western coastal region of Bangladesh is being affected by water logging – a problem related to climate change along with some manmade activities. Therefore, the study was conducted to assess the causes and consequences of this problem and highlights the responses of affected people to attract policy planners’ intention for taking proper intervention.
 Place and Duration of Study: The study was conducted in the Laboratory of Plant Ecology, Department of Crop Botany, Bangladesh Agricultural University, Mymensingh, Bangladesh.
 Methodology: Qualitative and quantitative techniques have been applied to collect and analyze both the primary and secondary sources of data from various waterlogged areas of south west Bangladesh.
 Results: There is no single or a few factors are responsible for creating water-logging problem rather it is a combination of several factors and their cumulative effects over time. It is revealed from the analysis of primary and secondary sources of information that death of Mathavanga River in the 20th century, execution of Coastal Embankment Project since 1960’s, withdrawing water flow to the Padma River through operating the Farakka barrage after independent of Bangladesh, improper management of rivers, faulty land-use by influential people in the areas, monsoon downpour etc are major causes of the problem. The silted up river systems in area could not drain monsoon rain that occurred even for a couple of days. The consequences brought to inundate hundred thousand hectares of cultivable land unsuitable for crop production. More than one million people are directly affected in the areas and the number is gradually increasing over the years. Water stagnancy around the settlement areas remains 6 to 9 months in a year and many places became permanently waterlogged. The affected people have no other way out but to live with water. The congested water is polluted with salinity, chemical effluents with heavy metals, household debris’s and related other pollutants. Source of safe drinking water is destroyed. Therefore incidences of waterborne and skin diseases are increased. People are living with greatest inhumanity as food, shelter, sanitation, communications, educations and other prime needs are tremendously challenged. Many people lost their occupations and became destitute, some altered their livelihood to much lower grades, and many of them are forced to migrate to city areas. The marooned people demanded to the authority to declare their places as an affected area and sought the government intervention to bring an end to the crisis through operating the Tidal River Management plan and excavating or re-excavating of associated rivers, channels and rivulets.
 Conclusion: The authority need to pay keen attention to the issue and should take proper initiative to mitigate the water-logging problem permanently to save people living in the south western coastal region of Bangladesh.

The effect of giving electric field to the metabolism of andaliman (Zanthoxylum acanthopodium DC) seeds which contributes to accelerating germination

Andaliman is a typical plant in Sumatera Utara that hasn’t been widely cultivated because it’s difficult to germinate. The aim of this research was to study the effect of giving an electric field to the metabolism of andaliman (Zanthoxylum accanthopodium DC) seeds which contributes to accelerating germination. Research conducted at the Laboratory of Plant Ecology, Tissue Culture Laboratory and Molecular and Genetic Laboratory of the Faculty of Agriculture, Universitas Sumatera Utara from June to July 2018 was arranged in a complete non-factorial randomized design repeated three times. Seeds are given by an electric field for 18 days with a voltage of 324 volts. The results of this research showed that the electric field treatment and differences in fruit colour not different significantly on seed metabolism in accelerating germination after do analysis of proteins, APX, SOD and electrical conductivity. Descriptively the highest average of APX was showed on without electric field: red colour seeds 2.39 μM/min/mg protein (P1). The highest average of SOD was showed on with electric field: red colour seeds 485.27 unit/mg protein (P4). The highest average of electrical conductivity was showed on without electric field: red colour seeds 6733.33 μS (P1).

No place to run

Plants never had it easy. When their ancestors colonized the land about 460 M years ago during the Ordovician period, they were immediately followed by crustaceans—which eventually developed into insects—that found plants a ready source of food. Ever since plants have been at the bottom of the food chain for pathogens and predators from viruses to mammalian herbivores. Unlike animals, plants cannot run away, having given up motility to maximize their surface exposed to sunlight. In lieu, they became masters in chemical warfare and communication to recognize and fend off pathogens and herbivores. Their “claws and teeth” are a dazzling arsenal of chemicals, metabolic and regulatory pathways, producing sensing and communication molecules that attract increasing interest from chemists and biologists for their potential use in medicine and agriculture. > Humans have also learned to use toxic compounds such as digitalis, atropine, opium or nicotine for medicinal, cosmetic or recreational use. Among these molecules are many spices, including the pungent piperine and capsaicin from peppers, or the glucosinolates from mustard and horseradish, and the bitter polyphenols, flavonoids or terpenes from red grapes, coffee beans, tea or cabbage. Humans have long come to appreciate these tastes—that originally evolved as a warning signal to herbivores—for centuries, spices were the most valuable commodity in global trade. Humans have also learned to use toxic compounds such as digitalis, atropine, opium or nicotine for medicinal, cosmetic or recreational use. The alkaloid taxol from the bark of the Pacific yew is a potent chemotherapeutic drug for cancer treatment; artemisinin, isolated from the plant Artemisia annua, or sweet wormwood, has long been employed in Chinese herbal medicine and been refined into a treatment for malaria. The metabolic pathways of plant compounds with medicinal value are therefore an active field of research with the objective of engineering these into E. coli or …

PRODUÇÃO DE MUDAS DE UMBUZEIRO (<i>Spondias tuberosa</i> Arruda Câmara) EM DIFERENTES SUBSTRATOS E TAMANHO DE RECIPIENTES

http://dx.doi.org/10.5902/1980509821092A espécie Spondias tuberosa Arr. Cam. (umbuzeiro) destaca-se como uma das espécies arbóreas de maior potencial do semiárido brasileiro. Apesar de sua relevante importância socioeconômica e ambiental, há falta de estudos voltados para o estabelecimento de um modelo de produção de mudas da espécie. O objetivo desse trabalho foi avaliar a produção de mudas de Spondias tuberosa utilizando diferentes substratos e tamanho de recipientes. O experimento foi conduzido no viveiro do Laboratório de Ecologia Vegetal (LEV) do Centro de Ciências Agrárias (CCA) da Universidade Federal da Paraíba (UFPB), Areia - PB. O delineamento experimental usado foi em blocos casualizados em esquema fatorial 2 x 7 e parcelas subdivididas, sendo que os recipientes representaram as parcelas e os substratos as subparcelas. Foram utilizados substratos formulados a partir da mistura de terra de subsolo (37,5-100%), areia lavada (12,5-25%) e esterco bovino curtido (10-50%). Os recipientes utilizados foram sacos de polietileno preto com volumes de 1900 cm3 (15 x 27 cm) e 5000 cm3 (25 x 26 cm). Para a obtenção das plântulas, sementes de Spondias tuberosa foram semeadas em sementeira de alvenaria até a repicagem (90 dias após o semeio). Aos 78 dias, após a repicagem, as mudas foram avaliadas quanto à altura, diâmetro do colo, relação altura/diâmetro do colo, diâmetro do xilopódio, comprimento de raiz, massa seca da parte aérea e raiz. Os dados obtidos foram submetidos à análise de variância e ao teste F, sendo as médias comparadas pelo teste de Tukey ao nível de 5% de probabilidade, utilizando o software SISVAR®. Os substratos com esterco bovino curtido proporcionaram os maiores valores em altura e comprimento de raiz. Para a produção de mudas de Spondias tuberosa, é recomendado o substrato contendo terra de subsolo (45%) + Areia (15%) + Esterco bovino (40%).

Pollen record of disturbed topsoil as an indirect measurement of the potential risk of the introduction of non-native plants in maritime Antarctica

This is a study of current pollen rain on soil disturbed by human use on the Fildes Peninsula, King George Island, South Shetland Islands. A sector strongly affected by human activity, an area between the Eduardo Frei Montalva Chilean Air Force (FACH) base and the Professor Julio Escudero base of the Chilean Antarctic Institute (INACH) were sampled. A less used sector associated with scientific activity and controlled tourism, Ardley Island, and an area of low human activity, the terminal moraine of the Collins glacier, were also sampled. The samples were collected in the southern summer of 2015 and kept in the Palynology and Plant Ecology Laboratory of the Los Angeles Campus of the Universidad de Concepcion, Chile. The area of greatest human activity concentrated the greatest diversity (12 taxa) of pollen grains. Three taxa are considered native to the region. Non-native taxa determined for this sector in turn had the greatest invasion (INV) factor. The dominant families were Brassicaceae and Asteraceae. The results for Ardley and Collins represent the cryptogamic flora and grasses typical of the ecosystem. Under the current climate change scenario, the pollen rain in Antarctic soil, in addition to obeying the random patterns of its natural dispersion, could be interpreted as an indirect measurement of the potential risk of the passive transport of propagules to Antarctica mediated by human beings.

Wisconsin Vegetation Database – plant community survey and resurvey data from the Wisconsin Plant Ecology Laboratory

Legacy data provide valuable baselines for assessing ecological changes. Excellent baseline data for Wisconsin's plant communities exist because of the surveys conducted by J.T. Curtis and colleagues (the Wisconsin Plant Ecology Laboratory or PEL) in the 1940s and 1950s. They surveyed > 2,000 sites to test how plant community composition varies along environmental gradients. These sites include upland and lowland forests, prairies, savannas, meadows, sand barrens, dunes, fens, and bogs. They devised new techniques to sample and compare plant communities. Their data include species lists and often quantitative data on occurrences and tree sizes. At intensively sampled prairies and savannas, data include cover and/or the composition of quadrats. At forested sites, researchers characterized the overstory by recording tree identity and measuring size and spacing using plotless methods. For the understory, they tallied all vascular species present in 20 (occasionally 40) spaced 1-m quadrats. Subsequent PEL researchers have resurveyed > 500 of these sites. The original quadrats and sites were not marked, requiring that resurveys approximate the original locations. Sampling uses either the original or more intensive protocols. We have characterized environmental conditions at many sites (soil chemistry, exotic earthworms, deer browse, and landscape conditions). We also now measure functional traits on many species. Our goals are to test theories of community assembly and assess how plant traits interact with patch size and landscape conditions to affect species and community dynamics. We have also redesigned sampling methods. The many sites and species provide great statistical power to characterize ecological changes and evaluate the factors driving these changes. These results serve to inform the public about ecological change and improve our ability to manage these communities wisely. Both the new and the legacy data are stored in the database Wisconsin Vegetation Database (GIVD ID NA-US-008).

Conservação de sementes de marizeiro <i>Geoffroea spinosa</i> Jacq. utilizando diferentes embalagens e ambientes

O marizeiro (Geoffroea spinosa Jacq.) é uma espécie florestal importante, sobretudo por ser adaptada às condições de matas ciliares do semi-árido e ecossistemas associados, ocorrendo em vastas áreas do Nordeste brasileiro e no vale do rio São Francisco, sempre restrita a ambientes sazonalmente inundados. Este trabalho teve como objetivos avaliar o efeito de diferentes tipos de embalagens e do período de armazenamento sobre o processo germinativo e o vigor de sementes de Geoffroea spinosa Jacq. acondicionadas também em diferentes ambientes. O experimento foi instalado no Laboratório de Ecologia Vegetal do CCA/UFPB, seguindo um delineamento inteiramente casualizado. As sementes foram distribuídas em dois ambientes (condições naturais, no laboratório e câmara fria), acondicionadas em dois tipos de embalagens (sacos de papel e sacos plásticos) durante cinco períodos de armazenamento: 0, 15, 30, 60 e 90 dias. Foram avaliados o teor de água, o índice de velocidade de emergência, a massa seca e o comprimento de plântulas. Os dados foram submetidos à análise de regressão polinomial. Na embalagem plástica e no ambiente de câmara fria, houve menor redução da viabilidade e do vigor ao longo do armazenamento. As sementes acondicionadas em sacos de papel e armazenadas em ambiente de laboratório perderam rapidamente a viabilidade e o vigor a partir dos 30 dias de armazenamento.

INFLUENCE OF PAR FLUX AND TEMPERATURE ON THE FLOWER BUD ABORTION OF ROSE (ROSA HYBRIDA CV. FRISCO) AND THE CARBON BALANCE OF THE SHOOT

The occurrence of flower bud abortion for rose, especially during winter, is attributed to a disequilibrium between the carbohydrate production in the sources and the demand for the assimilates in the sinks, caused by a low light intensity or a limitation of the translocation pattern. Manipulating the source and the sink strength by the light intensity and the translocation by temperature may lead to a reduction of flower abortion and an improved flower stem quality. An experiment was set up for roses (cv. Frisco) in 3 growth chambers of the Laboratory of Plant Ecology, including a control treatment (day/night temperature of 18116 degrees C and 300 mu mol-PAR), a low night temperature combined with high light intensity (18/12 degrees C; 300 mu mol PAR) and a low night temperature and low light intensity (18/12 degrees C; 100 mu mol-PAR). Measurements of the photosynthesis rate at shoot level (for a shoot length of 6 cm, 10 cm and 15 cm) and the carbohydrate content of several plant parts (also for different shoot lengths, corresponding with different developmental stages of the apex), as well as observations of the degree of abortion and the flower stem quality were performed. From the results, it was shown that the treatments influenced the rate of development of the shoot. The low night temperature, combined with the non-limiting light intensity enhanced the quality of the flower stem and decreased the abortion rate. Moreover, for a shoot length of ca. 10 cm (the critical stage of flower bud abortion), the quantum efficiency of the shoot and the carbohydrate content of the most mature leaf on the shoot were significantly higher than in the other treatments. The results support that a sufficient supply of carbohydrates during the critical stage for abortion, in combination with a high light intensity, which is known to enhance the sink strength, leads to a reduction of flower abortion and better flower stem quality.

Reanalysis of the Wisconsin Prairie Continuum

-Numerous prairie gradient studies have documented a significant correlation between soil moisture and compositional variation. The Wisconsin prairie gradient studies of J. T. Curtis and the Wisconsin Plant Ecology Laboratory (PEL) are among these and are widely cited. Data for 247 of the original Wisconsin PEL prairies were reordinated with Detrended Correspondence Analysis (DECORANA) ordination. The first axis of the ordination was highly correlated with the original Wisconsin prairie continuum. Sand prairies and wet-mesic prairies from extreme southeastern Wisconsin separated on the second axis. Measures of soil moisture were the highest correlate of the first axis. Latitude and longitude, pH, calcium, phosphorus, potassium, nitrate and ammonium nitrogen were also significant correlates of first or second axes. Discussions of pattern in prairie vegetation should look beyond simple correlations with soil moisture, and careful experimental and descriptive studies of prairie vegetation are still needed.
