Aim: The ‘abundant center’ hypothesis states that species are more abundant at the center of their range. However, several recent large-scale studies have failed to find evidence for such a pattern. Here we use extensive global data of reef fishes to test the strength of the 'abundant center' pattern, and to examine variation in the patterns across species using life history and ecological traits. Location: Marine habitat at a global extent: from Indo-Pacific to Atlantic...
Going against the flow: barriers to gene flow impact patterns of connectivity in cryptic coral reef gobies throughout the western AtlanticDaniel Volk, John Konvalina, Eric Hoffman, Sergio Floeter & Carlos E. L. Ferreira
Aim: Complex oceanographic features have historically caused difficulty in understanding gene flow in marine taxa. Here, we evaluate the impact of potential phylogeographic barriers to gene flow and assess demography and evolutionary history of a coral reef goby species complex. Specifically, we test how the Amazon River outflow and ocean currents impact gene flow. Location: Western Atlantic. Taxon: The bridled goby (Coryphopterus glaucofraenum) and sand-canyon goby (C. venezuelae) species complex. Methods: We used mitochondrial DNA...
Noninvasive fecal sampling in Itatiaia National Park, Brazil: wild mammal identification and parasite detectionLais Dib, Joao Pedro Palmer, Camila Lima, Jessica Pinheiro, Raissa Cristina Ramos, Claudijane Santos, Ana Beatriz Fonsceca, Karen Rodriguez-Castro, Camila Gonçalves, Pedro Galetti, Lais Correa, Otilio Bastos, Claudia Uchoa, Augusto Bastos, Maria Regina Amendoeira & Alynne Barbosa
Background: Noninvasive collection of feces is a cost-effective strategy for monitoring free-living wild mammals. The aim of this study was to search for carnivore and artiodactyl species and investigate the gastrointestinal parasites in their feces, in Itatiaia National Park, Brazil. Methodology/Main Findings: Between 2017 and 2018, feces from carnivores and artiodactyls were collected along trails in the park. Host species were identified from these feces through macroscopic and trichological examination and through molecular biology using...
Bird migration is typically associated with a latitudinal movement from north to south and vice versa. However, many bird species migrate seasonally with an upslope or downslope movement in a process termed altitudinal migration. Globally, 830 of the 6579 Passeriformes species are considered altitudinal migrants and this pattern has emerged multiple times across 77 families of this order. Recent work has indicated an association between altitudinal migration and diet, but none have looked at diet...
A blueprint for securing Brazil's marine biodiversity and supporting the achievement of global conservation goalsRafael A. Magris, Micheli D. P. Costa, Carlos E. L. Ferreira, Ciro C. Vilar, Jean-Christophe Joyeux, Joel C. Creed, Margareth S. Copertino, Paulo Horta, Paulo Y. G. Sumida, Ronaldo Francini-Filho & Sergio R. Floeter
Aim: As a step towards providing support for an ecological approach to strengthening marine protected areas (MPAs) and meeting international commitments, this study combines cumulative impact assessment and conservation planning approach to undertake a large-scale spatial prioritisation. Location: Exclusive Economic Zone (EEZ) of Brazil, Southwest Atlantic Ocean Methods: We developed a prioritisation approach to protecting different habitat types, threatened species ranges, and ecological connectivity, while also mitigating the impacts of multiple threats on biodiversity. When...
