Differential speciation rates, colonization time, and niche conservatism affect community assembly across adjacent biogeographical regions

Ronildo Benício, Diogo Provete, Mariana Lyra, Jani Heino, Célio Haddad, Denise De C. Rossa-Feres & Fernando Da Silva
Aim: To test the importance of evolutionary and biogeographic 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: i) why does the coastal region harbor more frog species than the inland region? and ii) how do these processes affect the relationship between the spatial variation of taxonomic, phylogenetic, and functional diversities within and across these regions? Location:...

Data from: Can matrix structure affect animal navigation between fragments? A dispersal experiment using release platforms

Vitor Sanches, Jorge Menezes, Jayme Prevedello, Almeida-Gomes Maurício & Luiz Gustavo Oliveira-Santos
The persistence of species in fragmented landscapes relies on landscape connectivity and individuals’ ability in dispersing among habitat patches. Accordingly, matrix structure can affect the orientation of dispersing individuals across the landscape. In this study, we measured the impact of matrix structure on the dispersal performance of the white-eared opossum (Didelphis albiventris). We released individuals in three types of matrix: bare field, corn crops and soybean crops, with distances of 30, 50 and 100 m...

The influence of biogeographical and evolutionary histories on morphological trait-matching and resource specialization in mutualistic hummingbird-plant networks

Martín González
Functional traits can determine pairwise species interactions, such as those between plants and pollinators. However, the effects of biogeography and evolutionary history on trait-matching and trait-mediated resource specialization remain poorly understood. We compiled a database of 93 mutualistic hummingbird-plant networks (including 181 hummingbird and 1,256 plant species), complemented by morphological measures of hummingbird bill and floral corolla length. We divided the hummingbirds into their principal clades and used knowledge on hummingbird biogeography to divide the...

Assessing the importance of reproductive modes for the evaluation of altitudinal distribution patterns in tropical frogs

Carla Siqueira, Davor Vrcibradic, Mauricio Almeida-Gomes & Carlos Frederico Rocha
Altitudinal patterns in species richness vary among taxa and are shaped by the intrinsic traits of different organisms and their response to environmental variables. We evaluated the relationship between anuran richness and elevation along local and regional altitudinal gradients within the Brazilian Atlantic Forest based on data from fieldwork (local dataset; 100-1,900 m a.s.l.) and on compiled secondary information (regional dataset; 0-2,300 m a.s.l.). We also tested whether frog distribution patterns were consistent with the...

Between June 2017 and August 2018, several municipalities located in Bahia state (Brazil) reported a large increase in the number of patients presenting with febrile illness similar to that of arboviral infections. Using a combination of portable whole genome sequencing, molecular clock and epidemiological analyses, we revealed the return of the CHIKV-ECSA genotype into Bahia. Our results show local persistence of lineages in some municipalities and the re-introduction of new epidemiological strains from different Brazilian...
