Genetická charakterizace tisu červeného (Taxus baccata L.) v širší oblasti Podyjí/Thayatal a na Svitavsku s vazbou na ochranářský management

The aim of the work is to determine the genetic diversity, genetic differentiation and genetic structure of subpopulations of the specially protected common yew in the area of South Moravian Podyjí (Czech Republic), Thayatal (Austria) and in the Svitavy region (Czech Republic) using DNA analyses (nSSR-nuclear Simple Sequence Repeats). The subjects of the analyses were yews of 1) natural occurrences in the territory of the Podyjí National Park (NP), 2) cultural origin in the Podyjí NP, 3) natural occurrences in the Thayatal NP (Austria), 4) natural occurrences outside the Podyjí NP, and 5) cultural origin in the Podyjí region outside the NP. For the comparison and better interpretation of results there also were analysed geographically more distant subpopulations, 6) natural occurrences in the Hřebečský ridge (NW Moravia), 7) cultural yew occurrences in the Svitavy region (NE Bohemia & NW Moravia), 8) natural occurrences in the Jílovské yews (N Bohemia), and 9) natural occurrences in the Moravian Karst (S Moravia). We observed higher level of genetic diversity (Ho = 0.54; He = 0.77), the FST with ENA correction ranged from 0.007 to 0.123. According to a STRUCTURE analysis, high genetic similarity was observed between samples from the Podyjí NP and Hřebečský ridge. The impact of the analysis results on the conservation management of tested populations was outlined.

Těžba lesního porostu ovlivňuje fenotyp živočichů: případová studie fluktuující asymetrie u střevlíka Notiophilus rufipes (Coleoptera: Carabidae)

We compared the rate of variability in the size of different body parts among three different treatments created by forest management (i.e. clearing, pole-stage stand, ecotone) in the Podyji National Park (Czech Republic). In order to describe changes, we used bioindicative values of the Carabidae (Coleoptera) with the example of Notiophilus rufipes (Curtis, 1829). We conducted fluctuating asymmetry (FA) of ten important metrical traits (e.g. antennal segments, length and width of third palpomer of the labial palpus). We found that specimens have sex specific association to FA of second antennal segment. The interaction of sex and treatment negatively affects the distribution of FA in polestage stand. We revealed that males had higher level of FA in pole-stage stand than females. Ecotones are zones where individuals from diverse habitats interact. Model of FA, with set sex as random effect, have positive association to litter and negative association to Collembola. This research contributes to forest management strategies by demonstrating how human-induced interventions influence eco-evolutionary link between stress and disturbance. The research suggests that for forest management, forest openings in thermophilic oak stands could support phenotypic variation in rare epigeic species.

Economic Assessment of Hydrologic Ecosystem Services in Morocco’s Protected Areas: A Case Study of Ifrane National Park

This study delves into the complex interplay between land use dynamics, hydrological services, and intangible benefits within the context of Ifrane National Park (INP) in Morocco. Due to its extensive mountain forests and numerous wetlands, INP is a crucial contributor to the nation’s water supply and a vital source of hydrological ecosystem services (HES). However, climate change and evolving land use patterns have led to diminishing water resources and the desiccation of certain wetlands. This research used the Integrated Valuation of Ecosystem Services and Tradeoffs software (InVEST 3.10.2) for HES quantification and environmental economics approach for monetization to comprehend how HES values respond to challenges posed by urbanization, intensive agriculture, and other land use alterations. This work underscores INP’s role as a significant “water tower”, emphasizing the evolution of its services amidst challenges. Our findings reveal an annual decrease in HES economic value by USD 4000. This economic assessment serves as a compelling tool to enlighten decision-makers and park users about the imperative need to preserve natural ecosystems and use water resources judiciously. It advocates for investments in conservation and restoration within protected areas to sustain these vital services.

Decoupling Sources of Anthropogenic Influences on Sediments of the Visovac Lake (Krka National Park, Croatia) Using Multiparametric Approach.

Historical changes of sediment characteristics and levels of inorganic and organic contaminants were studied in dated sediment cores from the Visovac Lake, situated in the Krka National Park, Croatia, to identify the main sources of anthropogenic pressures on this highly protected system. Depth distributions of lithogenic elements showed a steady decrease of terrigenous inputs due to the reduction in agricultural activities in the area, which was particularly pronounced during the 1991-1995 war in Croatia. Vertical and longitudinal distributions of Cd and Zn indicated that they are predominately of anthropogenic origin. The historical profiles of these toxic metals coincide well with the recorded production of metal industry in the upper reach of the Krka River with a sharp decrease reflecting the interruption by the war and slow recovery afterwards. By contrast, the recovery of the tourist industry in Krka NP after the war was accompanied by increasing contamination by elements characteristic of boat and car traffic (Sn, Cu, Pb) as well as oil pollution. The contamination with polycyclic aromatic hydrocarbons and polychlorinated biphenyls was only moderate. Although levels of metallic and organic contamination can be considered relatively low, the observed shift from industrial to tourism-related sources indicated that touristic activities should also be regarded as a possible threat for this vulnerable karst aquatic ecosystem.

Communicator whistles: A Trek through the taxonomy of the Boophis marojezensis complex reveals seven new, morphologically cryptic treefrogs from Madagascar (Amphibia: Anura: Mantellidae)

Abstract The Malagasy stream-breeding treefrog species Boophis marojezensis contains bioacoustically and genetically highly divergent populations. Some of these populations have been defined as candidate species and emit somewhat bizarre advertisement calls consisting of multiple whistle-notes. We here enable a long-overdue taxonomic revision of this species complex by applying a museomics approach to sequence DNA from the holotype of B. marojezensis. Based on an integrative approach that combines divergence levels in mitochondrial DNA and in three nuclear-encoded genes, morphological data, and bioacoustic comparisons, we conclude that eight different species exist in this complex, seven of which are formally described herein as new. Although morphological differences between species are small and mainly separate small-sized from larger-sized species, conclusive evidence for the new species comes from their sympatric and sometimes syntopic occurrence without haplotype sharing in three nuclear genes and under maintenance of bioacoustic differences. Uncorrected genetic divergences in the mitochondrial 16S rRNA gene are >3% in almost all cases, and in some cases up to 8%. In reference to the otherworldly sounds by which these frogs fill Malagasy rainforests, some of them reminiscent of sounds of technical equipment in the fictional “Star Trek” universe, we here name and describe the seven new species in honor of fictional captains of starships, namely B. kirkisp. nov., B. picardisp. nov., B. siskoisp. nov., B. janewayaesp. nov., B. archerisp. nov., B. pikeisp. nov., and B. burnhamaesp. nov. The majority of these species occur in northern Madagascar, where up to three species can occur in immediate geographical proximity, e.g., B. marojezensis, B. burnhamaesp. nov. and B. pikeisp. nov. at different elevations in the Marojejy Massif. South of 16°S latitude, only B. janewayaesp. nov., B. picardisp. nov., and B. kirkisp. nov. are found, with the latter extending southwards to Ranomafana National Park. Our study confirms the existence of numerous morphologically cryptic and microendemic species among Madagascar’s amphibians, some of which are known only from unprotected sites and require adequate conservation management.

Outcomes of an agri-environmental scheme in the management of common pastures in northern Portugal: Social benefits and effects on local capacity for collective action

Baldios are wide areas, integrated in extensive farming systems, historically held and managed by local communities for animal grazing and other extractive activities in support of their livelihoods. This land tenure regime persisted despite successive political and socioeconomic changes that threatened its communitarian nature, profoundly influencing the socioeconomic structure of rural areas. Today, use and possession of the baldios by the local communities is safeguarded by formal legal rights. In 2007 an agri-environmental scheme (AES) designed for managing the pastures in the baldios was proposed to the commoners of two protected areas. While one was successfully implemented and is still active, the other was discontinued. This study focuses on the Peneda-Gerês National Park experience, where the AES was widely adopted, aiming to understand the effects of its implementation on local dynamics for management of baldios, looking at its social and cultural benefits, particularly regarding local capacity for collective action. Semi-structured interviews were conducted in all the baldios in the park, and a period of stay in one of the villages allowed an opportunity for deeper analysis. Other stakeholders were also interviewed (e.g., state institutions). We argue that the benefits of this scheme went beyond the direct monetary payouts, playing an important role in the revitalization of local institutions. Moreover, we conclude that in depopulated and aging rural areas, top-down site-specific agri-environmental schemes that rely on existing social and institutional structures to operate are critical to recover and/or recreate institutions and practices for local collective landscape management.

Two new species of genus Labronema Thorne, 1939 (Nematoda, Dorylaimidae) from natural parks of Vietnam with an identification key to the species with a medium-sized odontostyle

Labronema Thorne, 1939 is a large and diverse dorylaimid genus with complicated taxonomy. Two new species, Labronema porosumsp. nov. and Labronema bidoupensesp. nov. from natural habitats in Vietnam were characterised both morphologically and molecularly (18S rDNA and 28 rDNA), and line drawings and microphotographs are provided. Phylogenetic analyses showed that the new species clustered together with Labronema ferox Thorne, 1939, the type species of the genus. The two new taxa belong to a group of Labronema species with medium body (L = 1.5–2.5 mm) and odontostyle (31–39 μm) length, and a lip region offset by a constriction. Based on morphological and molecular evidence, this study shows that the populations from Vietnam previously identified as L. glandosum Rahman, Jairajpuri, Ahmad & Ahmad, 1986 in fact represent L. porosumsp. nov. Evolutionary relationships of Labronema species are discussed. A key to the species of Labronema with a medium-sized odontostyle (31–39 μm) is provided as well as a list of the species of the genus considered valid.

The importance of fault control on the geomorphological development of a deep karst system: the case of Sima GESM, a Z-supercave in southern Spain

The mountainous karst massif in the Sierra de las Nieves (southern Spain) and the adjacent large outcrops of subcontinental mantle peridotites provide this area with a distinctive geodiversity that has contributed to the recent declaration of the zone as the new Sierra de las Nieves National Park. In addition, the Alpine tectonic interaction between the peridotites and the carbonate formations originated an important fault, the Turquillas fault, that has conditioned the existence of two tectonic blocks in the karst massif, one uplifted with respect to the other. Also, in the uplifted block, the fault has contributed to the generation of Z-supercaves, which are defined in this paper as caves with more than 1000 m of development in the vertical or Z dimension. Sima GESM with 1100 m of depth is the only Z-supercave known in the giant geologic structure of the Gibraltar Arc, which speaks on the infrequent and exceptionality of the generation of these underground geomorphological systems. The task of this paper is to present a detailed study of the Turquillas fault and its influence in the surface and underground geomorphology and hydrogeology and in particular its influence and implications in the development of the deep karst system defined as the Z-supercave. It is hoped that this study will contribute to identify the necessary conditions for the development of these extraordinary geomorphic systems which are of great international relevance in the major mountain ranges of the world with high relief karst and deep karst systems.

Investigations on the Health Status and Infection Risk of Harbour Seals (Phoca vitulina) from Waters of the Lower Saxon Wadden Sea, Germany

Harbour seals (Phoca vitulina) are the most common pinniped species in the Wadden Sea of Schleswig-Holstein, Hamburg and Lower Saxony, Germany. Their numbers have recovered after significant depletion due to viral outbreaks and effects of anthropogenic activities like pollution and habitat disturbance. Within the Wadden Sea National Park of Lower Saxony the harbour seal is protected. As a top predator in the Wadden Sea ecosystem, the harbour seal is a sentinel species for the state of the environment. Between 2015 and 2017, a total of 80 stranded dead harbour seals were collected along the coastline of Lower Saxony and submitted for pathological investigations. Of these, 70 seals were born in the same year (0–7 months, age group 1) and eight in the previous year (8–19 months, age group 2), due to high mortality rates in these age groups. However, two perennial animals were also available for examination during this period, one of which was in good nutritional condition. Many of the seals that had been mercy-killed and found dead were in poor nutritional status. Histopathological, microbiological, parasitological and virological examinations were conducted on 69 individuals (86% (69/80)) in a suitable state of preservation. Respiratory tract parasitosis, cachexia, and bronchopneumonia were the most common causes of death or disease. Overall, there was no evidence of a relapse of a viral disease outbreak. Macrowaste, such as plastic waste or fishery-related debris, were not found in any gastrointestinal tract of the animals examined. There was also no evidence of grey seal predation. Weakness and cachexia were prominent causes of disease and death in harbour seals found within a few weeks after birth, but bronchopneumonia and septicaemia also developed in slightly older animals. Frequently found microbial pathogens in seals from Lower Saxony were similar to those found in other studies on seals from the Wadden Sea region in Schleswig-Holstein, for example streptococci and Escherichia coli/v. haemolytica, Brucella spp. and Erysipelothrix rhusiopathiae, potentially human pathogenic germs. The results of the examinations of dead harbour seals from Lower Saxony show that pathological investigations on a representative number of animals deliver urgently needed information on the health status of the population. The results represent an important contribution to the state of the top predators of the Wadden Sea as part of the obligations within the Trilateral Wadden Sea Agreement, Oslo and Paris Convention for the Protection of the Marine Environment of the North-East Atlantic (OSPAR) and the Marine Framework Directive. The investigations should be continued as a matter of urgency and the stranding network should be expanded.

Preparedness and Response to Flooding Risks by Kenya Wildlife Service in Hells Gate National Park, Nakuru County, Kenya

Floods are short-lived events that occur abruptly with little to no warning and are among the most dangerous disasters relating to weather due to the hazardous conditions caused for people, the destruction of property and the loss of life as well. Thus, minimizing flooding impacts timely and passing accurate information is critical in flood preparedness and response. Previous studies have focused on the probability of floods occurring and their magnitude, therefore leaving a knowledge gap on preparedness and response to flooding risks in national parks by government agencies in Kenya. Hell’s Gate National Park experiences significant flash flooding; therefore, it provided a good venue to study the levels of preparation and response mechanisms available in Kenyan national parks. The objectives of the study were to understand the level of preparedness and mechanisms to respond to flooding events by Kenya Wildlife Service in Hells Gate National Park. The study was guided by a descriptive research design which involved collecting quantitative and qualitative data from 118 park users and other key informants. The study found that the Kenya Wildlife Service plays a crucial role in flood preparedness and response, but there is room for improvement in early warning systems, hazard map distribution, and user education because only 36.6% of the respondents were aware of escape routes to be used during floods. In terms of recommendations, the study found that it is crucial to enhance the existing flood preparedness and response mechanisms within the park including investing in advanced technology for early warning systems, conducting regular drills, and fostering community engagement and partnerships, continuous improvement of flood preparedness and response plans, along with a robust communication strategy.

Diversity and Host Specificity of Avian Haemosporidians in an Afrotropical Conservation Region

Afrotropical regions have high bird diversity, yet few studies have attempted to unravel the prevalence of avian haemosporidia in conservation areas. The diversity and host specificity of parasites in biodiversity hotspots is crucial to understanding parasite distribution and potential disease emergence. We test the hypothesis that biodiverse regions are associated with highly diverse parasites. By targeting the cytochrome b (Cytb) gene, we molecularly screened 1035 blood samples from 55 bird species for avian haemosporidia infections to determine its prevalence and diversity on sites inside and adjacent to the Kruger National Park. Overall infection prevalence was 28.41%. Haemoproteus, Leucocytozoon, and Plasmodium presented prevalences of 17.39%, 9.24%, and 4.64%, respectively. One hundred distinct parasite lineages were detected, of which 56 were new lineages. Haemoproteus also presented the highest diversity compared to Leucocytozoon and Plasmodium with varying levels of specificity. Haemoproteus lineages were found to be specialists while Plasmodium and Leucocytozoon lineages were generalists. We also found a positive relationship between avian host diversity and parasite diversity, supporting an amplification effect. These findings provide insight data for host–parasite and co-evolutionary relationship models.

Rapid Appraisal of Wildlife Corridor Viability with Geospatial Modelling and Field Data: Lessons from Makuyuni, Tanzania

Connectivity between protected areas is necessary to prevent habitat fragmentation. Biodiverse countries like Tanzania craft legislation to promote habitat connectivity via the creation of ecological corridors, but their viability for wildlife often remains unknown. We therefore develop a scalable and replicable approach to assess and monitor multispecies corridor viability using geospatial modeling and field data. We apply and test the approach in the Makuyuni study area: an unprotected ecological corridor connecting Tarangire National Park to Essmingor mountain, Makuyuni Wildlife Park and Mto Wa Mbu Game Controlled Area. We analyzed the viability of Makuyuni as an ecological corridor by creating and validating a geospatial least-cost corridor model with field observations of wildlife and livestock. We created the model from publicly available spatial datasets augmented with manual digitization of pastoral homesteads (bomas). The least-cost corridor model identified two likely pathways for wildlife, confirmed and validated with field observations. Locations with low least-cost values were significantly correlated with more wildlife observations (Spearman’s rho = −0.448, p = 0.002). Our findings suggest that Makuyuni is a viable ecological corridor threatened by development and land use change. Our methodology presents a replicable approach for both monitoring Makuyuni and assessing corridor viability more generally. The incorporation of manually digitized homesteads (bomas) and field-based livestock observations makes corridor assessment more robust by taking into account pastoral land uses that are often missing in land cover maps. Integration of geospatial analysis and field observations is key for the robust identification of corridors for habitat connectivity.

Natural resources used in the traditional medicine of the Marinaú community, Caxiuanã forest, Brazil

BackgroundThe diversity of Conservation Units in Brazil, ranging from Strict Protection areas like National Parks to Sustainable Use areas such as National Forests, supports the coexistence of human populations with extensive traditional knowledge of local natural resources. This traditional and local knowledge plays a crucial role in their subsistence and has significant potential to contribute to bioprospecting initiatives, as well as to enhance research and strategies for biological conservation. The São Sebastião de Marinaú community, situated within the Caxiuanã National Forest, offers valuable opportunities for ethnobiological studies.MethodsThe field study was carried out with 48 informants from the São Sebastião de Marinaú Community, Caxiuanã National Forest (CNF), Brazil, a Sustainable Use Conservation Unit. It involved participant observation, semi-structured interviews, and guided tours. Indices of Use Value (UV), Fidelity Level (FL), and Consensus Factor (ICF) indicated plant species with therapeutic potential.ResultsA total of 944 uses associated with 154 plants and 21 animals were reported. Statistical tests pointed out that factors such as gender and age are not determinants in the richness of known plants among the residents. The plants are distributed among 59 botanical families and 126 genera. They predominantly use species native to Brazil (69%), among which 47 are endemic to the Amazon. The medicines are prepared mainly by decoction of leaves and bark. According to UV, veronica (Dalbergia monetaria L.f.) was the most important. The animals used are all vertebrates, and paca (Cuniculus paca Linnaeus, 1766,) was the most cited. Bile and lard are the parts most used in the recipes. They mentioned 116 diseases, especially those of the digestive system. The ceruzeiro (Allantoma lineata (Mart. ex O.Berg) Miers) had a high consensus of local use, and no additional studies on this species exist.ConclusionThis study underscores the vital role of traditional communities in sustainable conservation units, as their involvement is crucial for preserving plant and animal species essential to local traditional medicine. Such research also promotes the recognition of non-timber products as valuable raw materials with potential applications in the chemical and pharmaceutical industries. Additionally, mapping the occurrence and use of species in vulnerable conditions aids in developing effective conservation strategies for these resources.

Global Gain, but Local Loss—National Park and Municipal Revenues in Poland

The paper analyzes the problem of stagnation in the creation of new national parks in Poland, identifying key barriers and proposing solutions. The background to the study refers to the role of national parks in nature conservation, but at the same time highlights the problem of the limited development of the park network in Poland, which remains at 1.05% of the country’s area—well below the EU average. The main obstacles identified by the author are the resistance of local governments due to the reduction in forest tax revenues and the differences in salaries between employees of national parks and state forests. Research methods included legal and economic analysis and a review of the literature on national park management. The results indicate that the problem can be solved by adequate financial compensation to local communities and the introduction of a co-management model that integrates the interests of local governments and parks. The article suggests that a change in the approach of the government administration and a more participatory management model can help to break the stagnation and increase the number of national parks, which is relevant not only for Poland but also for other countries struggling with similar challenges.

A brief history of primate research in the Ndoki forest.

The Nouabalé-Ndoki National Park (NNNP) in Republic of Congo has become a beacon for conservation in Central Africa. This manuscript documents the arrival of primatologists, the establishment of field stations and major discoveries in primate behavior and ecology. Field stations were strategically established to study primate behavior in a variety of different contexts from stationary platforms to forest follows of habituated groups. The implementation of new technologies and analyses have also been a hallmark of research at Ndoki. Scientists are shaping a new era in primatology at NNNP by building on past successes and promoting the next generation of Congolese conservationists to address environmental challenges. Results have proven crucial in discussions with government and industry and led to conservation gains such as the inclusion of the intact forests of the Goualougo and Djéké Triangles into the NNNP. The research stations have also become essential for developing a long-term certified sustainable international gorilla tourism program. Despite the many advancements for conservation such as increased protection of forests, development of internationally recognized protocols and large-scale capacity building initiatives, there are reasons for considerable concern in the near- and long-term for primates and their forest habitats in the Ndoki landscape. To address these concerns, we emphasize the long history of forming partnerships with local communities. We also discuss shared overlap featuring multicultural and environmental use of forest resources that is likely to be crucial in championing the conservation of the Ndoki forests for the next 25years and beyond.

How does anthropogenic food influence the trophic ecology of Rocky Mountain Red Fox?

Abstract Providing novel food subsidies to wildlife can influence behavior, resource use, disease dynamics, and food web interactions. Studies examining impacts of anthropogenic food have primarily occurred in urban landscapes where anthropogenic resources are consistently accessible. National parks, however, experience similar issues regarding wildlife exploiting anthropogenic food, but access to anthropogenic food is contingent on human visitation, which can fluctuate dramatically between seasons. We evaluated how fluctuating availability of anthropogenic food and demographic factors influenced the isotopic niche of Rocky Mountain Red Fox (Vulpes vulpes macroura) at the population and individual level in Grand Teton National Park, Wyoming. From 2016 to 2021, we assessed diet-related questions by collecting 55 whisker samples and 52 hair samples from 40 unique individuals and analyzed them using stable isotope analysis (δ13C and δ15N). We discovered that Rocky Mountain red foxes have a broad isotopic niche, with seasonal differences in their consumption of anthropogenic food. Contrary to our expectations, foxes demonstrated increased reliance on anthropogenic food (higher δ13C values) during winter months, whereas natural food consumption or dietary mixing was more prominent in summer months. Natural food scarcity could be driving foxes to seek out more anthropogenic food in the winter, whereas the increased abundance of natural food items in the summer could result in a lower need for foxes to supplement their diet with anthropogenic food. Adults had consistently higher δ13C values relative to juveniles, indicating either intraspecific variation in boldness or dominance leading to increased exploitation of anthropogenic food, which could be a learned behavior coinciding with habituation. Finally, we observed that increasing densities of human features within the home range of a fox was a strong predictor of anthropogenic food reliance at the individual level. Our work provided a deeper understanding of the trophic ecology of Rocky Mountain Red Fox in relation to human activity in a nature preserve, and equipped managers with insight into potential patterns associated with food-conditioned foxes.

Key Determinants of Visitor Satisfaction and Post- Visit Intentions at a Museum in the Kruger National Park, South Africa

Museums preserve and present valued historical artifacts, information, and displays to an information-hungry tourism market. As such, they play a crucial role in the tourism industry, serving as pertinent leisure attractions in many destinations. It is therefore important for management to identify the key determinants that lead to tourist satisfaction and to tourists’ intention to return in future. This knowledge could assist management in making the informed strategic decisions for sustaining such attractions. Very little research has been conducted on this aspect in terms of museums in South Africa, leaving numerous unanswered questions about tourists’ experiences, the perceived quality of sites and tourists’ satisfaction with sites, which ultimately impact their intention to return. A quantitative survey was conducted at the Stevenson-Hamilton Knowledge Resource Centre and Museum (Skukuza Museum) in the Kruger National Park, where a total of 164 responses were obtained. Eight hypotheses were formulated and tested by utilizing Spearman’s correlation, investigating visitor expectations, experience, perceived quality, satisfaction, pleasure, confirmation and visitor intent. The results confirm the hypothesis that when tourists’ expectations are met, they experience a positive service experience and perceive the high quality. When tourists derive pleasure and satisfaction from the visit, they usually commit to a follow-up visit. The results of this study provide a basis for museum management, public sector visitor attractions, employees and academia to further develop these museums as successful visitor attractions.

Can the Ecological Appearance Hypothesis explain the use of medicinal plants in the region of Sete Cidades National Park in Northeast Brazil?

O uso histórico de plantas no tratamento de doenças persiste hoje como uma terapia alternativa, especialmente em regiões rurais e em desenvolvimento, devido a fatores culturais e econômicos. Este estudo teve como objetivo documentar e analisar o uso medicinal de espécies vegetais em uma comunidade rural próxima ao Parque Nacional de Sete Cidades, Piauí, com base na Hipótese da Aparência Ecológica. Foram conduzidas entrevistas semiestruturadas com 27 membros da comunidade e um levantamento fitossociológico usando o método do ponto quadrante. Os métodos de Valor de Uso, Importância Relativa e Frequência Relativa de Citação avaliaram o uso e a versatilidade das espécies. Os dados não corroboraram a hipótese, indicando a influência de fatores como disponibilidade sazonal, adaptação cultural, diversidade de habitat, percepção humana e mudanças ambientais na seleção de plantas medicinais em ambientes de cerrado e caatinga. Uma compreensão abrangente requer estudos detalhados considerando não apenas a visibilidade das plantas, mas também os contextos culturais, sazonais e ambientais específicos que moldam as práticas medicinais, permitindo uma compreensão holística da relação entre comunidades humanas e flora medicinal em ambientes de floresta seca.
