Linking changes in landscape structure to insect herbivory in forest edges and interiors of Atlantic Forest remnants

Ecological Applications, Год журнала: 2024, Номер 34(7)

Human activities have triggered profound changes in natural landscapes, resulting species loss and disruption of pivotal ecological interactions such as insect herbivory. This antagonistic interaction is affected by complex pathways (e.g., abundance herbivores predators, plant chemical defenses, resource availability), but the knowledge regarding how forest fragmentation affect herbivory human-modified tropical landscapes still remains poorly understood. In this context, we assessed multi-pathways which landscape structure likely influence 20 Atlantic fragments Brazil. Using path analysis, estimated direct effects cover edge density, indirect effect via canopy openness, number understory plants phenolic compounds, on leaf damage located interior fragments. particular, edges experienced greater than ones. We observed that density exerted a positive sampled at Our findings also indicated increase led to an opening interior, causes reduction and, consequently, damage. addition, detected compounds negatively plants. Given increasing regions, become stranded highly deforested, edge-dominated degraded our study highlights pervasive enhancement remaining fragments-especially along gaps interior. As result, increased regeneration accelerate meltdown processes these deforested disturbed anthropogenic landscapes.

An empirical model for branding oriented by the environmental sustainability of the Amazon Rainforest: a hybrid structural equation modeling with fsQCA approach

Discover Analytics, Год журнала: 2024, Номер 2(1)

Опубликована: Март 25, 2024

Abstract Utilizing the Theory of Planned Behavior, a meaningful connection between an organization and its consumers can be established, transcending mere appearances delving into emotions, relationships, brand experiences. In line with these principles, this study aims to present empirical model grounded in factual evidence derived from perspectives entrepreneurs environmentally sustainable brands Brazilian Amazon. The proposed adopts mixed-modeling approach, utilizing data analysis techniques such as fuzzy-set qualitative comparative (fsQCA). Two independent sets were collected: one 8 companies operating Amazon rainforest another 535 potential consumers. By analyzing datasets, consumer motivations for consumption brands, entrepreneurial practices, role traditional communities forest environment shaping perceptions identified. results reveal that, consumer’s perspective, key factors influencing positive inclination purchase include brand’s engagement com munities, perceived product quality, innovation, transparently communicated positioning strategy. These constructs form core components main solution. This article provides valuable information tropical forests well policymakers community-based entrepreneurship. It is also interest researchers individuals involved management strategy empowering small businesses engaged practices community collaboration. study’s findings recommendations have foster more socially responsible business thereby enhancing local economies contributing environmental preservation.

Neotropical non‐primate canopy mammals: historical trends, omissions, and geographic gaps in the knowledge

Mammal Review, Год журнала: 2024, Номер unknown

Опубликована: Июль 22, 2024

ABSTRACT Canopy mammals constitute a diverse and widely distributed group. However, these species have not been studied, there are currently many gaps in our knowledge of their ecology, behaviour, distribution, conservation status. We identified crucial trends omissions terms research effort on themes, taxonomic groups, countries, protected areas (PAs) geographic information biases. A systematic review was conducted by consulting two electronic databases (Web Science Scopus), including within neotropical countries (from central Mexico to northern Argentina) until the end first half 2021. All references obtained were reviewed categorised, geographical location each study extracted evaluate gaps. found that orders (Carnivora Didelphimorphia) three families (Didelphidae, Felidae, Cricetidae) most studied taxa, featured more than 50% cases. Brazil had highest number studies. Topics concerning diseases (19% cases), distribution (14%), ecology (14%) frequently addressed; only 4.6% studies focused anthropogenic disturbances, less 30% PAs. one largest important biases Amazon region, where low or null. This lays groundwork for future understudied mammals, develop better can allow us design appropriate strategies.

The influence of domestic dogs on the spatial and temporal distribution of tayra

The domestic dog Canis familiaris is an exotic species known to have impacts on native fauna and it may induce spatial temporal segregation in other as a mechanism reduce agonistic interactions. tayra Eira barbara , medium‐sized, widely distributed mustelid, one of the that can be affected. To test this hypothesis, between 2020 2022, we installed camera traps agricultural landscape composed protected area, agro‐livestock areas, urban several rural households. We calculated activity patterns, their overlapping coefficients generated models explain species's occupancy verify possible interferences. obtained 32 records tayras 100 dogs. In only 8 73 sampling points, two occurred concomitantly. Activity overlap was 68%; however, at points where both occurred, 43%. Tayra showed positively associated with forest negatively exploitation areas. Dogs predominantly occupied areas were related addition interference, which seems affect tayra's use landscape, environmental conditions are also essential describing subordinate species.

Genetic Diversity of Ishpingo Exploited Trees (Ocotea quixos (Lam.) Kosterm, Lauraceae)

Опубликована: Дек. 16, 2024

Ocotea quixos (Lam.) Kosterm, known as Ishpingo, is a tree endemic to the Amazonian rainforests of Colombia, Ecuador, and Peru. In Ishpingo faces significant threats due overexploitation for its valuable spices essential oils, well extensive deforestation land-use changes. Understanding preserving genetic diversity vital ensuring species' survival continued contribution ecological cultural richness rainforest. Nevertheless, we currently lack comprehensive data. Within this scenario, developed nuclear microsatellites analyze in ten Ecuadorian populations Ishpingo. Results show low levels diversity, especially when compared with other trees. The mean number alleles ranged from 2.20 4.47, observed heterozygosity 0.33 0.62, while expected (He) was notably higher, ranging 0.61 0.79. inbreeding coefficient (Fis) consistently positive, some values close zero. Despite these results, such northern still harbor moderate key preservation species.

Impacts of anthropogenic habitat modification on mammalian diversity in the Mau Forest Complex, Kenya

Global Ecology and Conservation, Год журнала: 2024, Номер 54, С. e03066 - e03066

Habitat destruction is a major driver of biodiversity loss, especially in the tropics. We investigated changes diversity and occupancy forest-dwelling mammals response to habitat alteration, degradation at Mau Forest Complex (MFC), southwestern Kenya. Using systematic camera trapping grid, we estimated patterns mammalian diversity, small carnivores, detection rates functional groups across three types (primary forests, secondary cultivated habitats). Between March 2019 October 2021, 246 traps were deployed 181 locations representing 5509 sampling days, resulting 47,345 images 52 species nine orders. Alpha differed among treatments, with primary forests having highest habitats lowest, though results not statistically significant. Beta significantly indicating differences community composition as well richness. Overall for carnivores was lowest habitats, some specializing while others able occupy more degraded habitats. Among groups, only large rodents, primates, ungulates. Our indicate that although may respond differently loss alteration MFC, overall specialist less-disturbed forests. Specialist, forest-dependent are likely most affected by human activities, making them vulnerable MFC.
