Human‐induced high densities of large wild herbivores may pose a threat to natural ecosystems, modifying biodiversity and ecosystem functioning. Although the negative impacts on individual taxa and processes are well documented, a comprehensive understanding of how ecosystem integrity responds to high herbivore densities remains limited. This study addresses this gap through an extensive herbivore‐density manipulation experime...
Presence of micro-mesoplastics in beaches and sediments of São Francisco do Sul (Brazil)NARA Subscribed
The coastal environment is a critical interface for monitoring plastic pollution. This study investigated microplastics (MPs, < 5 mm) and mesoplastics (MePs, 5–25 mm) in Praia Grande, São Francisco do Sul (SC State, Brazil), using stereomicroscopy and ATR-FTIR spectroscopy. Two sites with contrasting urbanization and tourism levels were assessed. Area #1, the more urbanized site, exhibited higher concentrations of MPs (70.44 p...
Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R packag...
MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugalNARA Subscribed
Mammals are threatened worldwide, with ~26% of all species being included in the IUCN threatened categories. This overall pattern is primarily associated with habitat loss or degradation, and human persecution for terrestrial mammals, and pollution, open net fishing, climate change, and prey depletion for marine mammals. Mammals play a key role in maintaining ecosystems functionality and resilience, and therefore information o...
Aim To test the importance of evolutionary and biogeographical processes in shaping the assembly of local frog communities in two adjacent regions (hereafter, coastal and inland regions) with different historical signatures. We asked two main questions: (1) why does the coastal region harbour more frog species than the inland region? and (2) how do these processes affect the spatial variation in taxonomic, phylogenetic and fun...
Motivation The BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These data enable users to calculate temporal trends in biodiversity within and amongst assemblages using a broad range of metrics. BioTIME is being developed as a community‐led open‐source database of biodiversity time series. Our goal is to accelerate and facilitate quantitative analysis of temporal...
A phylogenetic analysis of Pseudopaludicola (Anura) providing evidence of progressive chromosome reductionNARA Subscribed
Here, we present a molecular phylogenetic analysis of the Neotropical genus P seudopaludicola focusing on species relationships including 11 of the 17 known species of P seudopaludicola ; several samples of P seudopaludicola are not assigned to any species; and 34 terminal species as an outgroup. The study was based on the analysis of approximately 2.3 kb of the sequence of the mitochondrial 12S rRNA , tRNA val and 16S rRNA ge...
