Knowledge on biodiversity is fundamental for conservation strategies. The Brazilian Pampa region, located in subtropical southern Brazil, neglected terms of conservation, and knowledge its fragmented. We aim to answer the question: how many, which, species occur Pampa? In a collaborative effort, we built lists plants, animals, bacteria, fungi that Pampa. included information distribution patterns, main habitat types, status. Our study resulted referenced totaling 12,503 (12,854 taxa, when...
The primary consequence of global warming for reefs is coral bleaching, often leading to extensive mortality. Although bleaching well-documented globally, the thermal stress and experienced by unique South Atlantic remain largely unknown due insufficient monitoring on both spatial temporal scales. Therefore, this work aimed reconstruct past episodes across reefs, assessed whether are becoming more intense, longer-lasting, frequent. We retrieved daily 5 km-resolution Degree Heating Week (DHW)...
Abstract Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential integrity landscapes where they occur. Carnivores also hold high conservation value their habitat requirements guide management plans. The order Carnivora has 84 species from 8 families the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; Ursidae. Herein, we include published unpublished data on native terrestrial (Canidae;...
Biological invasion is one of the main threats to native biodiversity. For a species become invasive, it must be voluntarily or involuntarily introduced by humans into nonnative habitat. Mammals were among first taxa worldwide for game, meat, and labor, yet number in Neotropics remains unknown. In this data set, we make available occurrence abundance on mammal that (1) transposed geographical barrier (2) Neotropics. Our set composed 73,738 historical current georeferenced records alien which...
Abstract Aim Body size variation in animal assemblages is a widely addressed pattern biogeographical studies, and affected by both environmental gradients phylogenetic constraints. However, no study has yet explored to what extent the association between body across broad spatial scales influenced distribution of different lineages. In this study, we discriminate influences variables community composition on South American sigmodontine rodents. Location America. Methods We computed mean mass...
Abstract Aim Functional diversity encapsulates whole‐community responses to environmental gradients mediated by species traits. Under trait convergence, similar may cause distantly related taxa exhibit spatially correlated functional diversity. We investigated whether of reef fish, coral and algal richness disparity the environment produce patterns. Location Brazilian marine biogeographical province. Taxon Reef corals, algae. Methods analysed data from 40 coastal oceanic sites distributed...
Abstract The emergence of functional ecology has changed the focus ecological research from investigating patterns species diversity to understanding how traits relate specific processes generating these patterns. Traits, and can be shared driven by distantly related taxonomic groups. Crossing boundaries among groups is still a challenge critical knowledge frontier in ecology. A cross‐taxa approach, merging trait data across groups, could fill this gap. In context, functionally analogous...
Abstract Marginal reefs sustain coral assemblages under conditions considered suboptimal for most corals, resulting in low abundance. These are inhabited by numerous fishes with a generally unknown degree of association corals that might lead to the assumption play minor roles determining fish occurrence, when could be actually sustaining diverse and resilient assemblages. Using site-occupancy models fitted data 113 reef species different life stages (adults juveniles) from 36 distributed...
Abstract Aim Speciation, extinction and historical dispersal are the ultimate factors generating maintaining biodiversity. However, methods of macroevolution used to detect processes usually ignore variation macroevolutionary at scales finer than entire regions. Likewise, biogeography community ecology often deep‐time evolutionary processes. To overcome this problem, it is necessary integrate data from ancestral state reconstructions, current species distributions biogeographical...
In this paper, we discuss some key aspects for the maintenance of biological diversity in grassland–forest mosaics southern Brazil (Campos Sulinos) not explored yet. Campos Sulinos are grasslands distributed throughout Pampa and Atlantic Forest biomes. Since these remain from past dryer colder climatic conditions, they acknowledged as native rather than anthropogenic ecosystems (Pillar Velez, 2010). The form with shrubby forest physiognomies belonging to Araucaria seasonal forests Brazil,...
Abstract The relative roles of historical processes, environmental filtering, and ecological interactions in the organization species assemblages vary depending on spatial scale. We evaluated phylogenetic morphological relationships between individuals (i.e., inter‐ intraspecific variability) Neotropical nonvolant small mammals coexisting grassland‐forest ecotones, landscapes regions, that is, three different scales. used a tree to infer evolutionary relationships, traits as indicators...
Habitat suitability for mammal species in grassland/forest ecotones may be affected by changes abiotic conditions (e.g. light incidence), grazing and burning disturbances, woody encroachment. We evaluate models addressing the role of such factors on structuring non-volant small assemblages considering (1) only disturbed (2) all (disturbed undisturbed). A complete model (i.e., gradients, disturbances encroachment) was most plausible abundance ecotones, niche similarity both ecotones. Niche...
Livestock is promoting the global collapse of mammal populations. The discovery best management practices that reconcile conservation with production urgently needed. We evaluated effect cattle grazing on occupation three rodent species (Akodon azarae, Oligoryzomys flavescens and Oxymycterus nasutus). collected habitat covariates sampled rodents, using live traps tracking tunnels, in 20 paddocks subjected to different pressures, from two research stations, across four seasons. applied...
Human activities and climate change have accelerated species losses degradation of ecosystems to unprecedented levels. Both theoretical empirical evidence suggest that extinction cascades contribute substantially global loss. The effects can ripple across levels ecological organization, causing not only the secondary loss taxonomic diversity but also functional erosion. Here, we take a step forward in coextinction analysis by estimating robustness reef fish communities We built tripartite...
ABSTRACT Male gladiator frogs of Hypsiboas Wagler, 1830 build nests on available substrate surrounding ponds and streams where female spawn eggs during the breeding period. Although seem to show plasticity in way they construct their nests, there is no study reporting if these species present preferences about microhabitat conditions for nest-building (mainly under subtropical climate). Predation pressure environmental have been considered major processes shaping great diversity reproductive...
Among the 251 described species of ticks from genus Ixodes, only eight were previously reported in Brazil, Ixodes amarali, aragaoi, auritulus, fuscipes, loricatus, luciae, paranaensis and schulzei. Of those species, I. loricatus is considered commonly found, whereas auritulus aragaoi registered just one time Rio Grande do Sul (RS) state, Southern Brazil. This paper aims to update occurring RS through investigation ixodofauna small rodents. Data 314 wild rodents analyzed nine municipalities...
Climate seasonality may differently influence habitat quality and heterogeneity depending on type. We examined whether the taxonomic, functional phylogenetic composition of ground-dwelling anuran assemblages from grassland forest habitats vary seasonally. tested hypothesis that assemblage varies less seasonally than assemblage. monitored anurans using pitfall trap arrays in two areas, sampled across four seasons over a two-year period. For composition, we acquired information species...
