Elevation drives taxonomic, functional and phylogenetic β‐diversity of phyllostomid bats in the Amazon biome

Abstract

Aim:We evaluated the relative importance of geographical and environment variables for taxonomic, phylogenetic and functional β-diversity of phyllostomid bats along the entire Amazon biome and specifically in the lowlands.Location: Amazon biome.Taxon: Chiroptera. Methods:We carried out a bibliographic review and compiled a wide and unprecedented database of 106 phyllostomid bat species at 102 sites throughout the Amazon biome. For all possible pairs of sites in both datasets, we estimated the Jaccard pairwise dissimilarity, that is, β-diversity, considering its three dimensions-taxonomic, phylogenetic and functional-for its two components-turnover (substitution of species) and differences in species richness. The association between dissimilarity measurements and geographical and environment variables was assessed using multiple regressions on distance matrices (MRM). Results:We found that turnover and differences in species richness had similar contributions to the taxonomic β-diversity. However, for phylogenetic and functional β-diversity, lineages and functions richness differences contribute slightly more than

Abiotic Drivers of Bat Community Diversity in a Savanna Mosaic across the Tropical/Subtropical Transition of South America

“…Recently, Carvalho et al . (2022) compiled an extensive literature-based evaluation of bat community diversity across multiple communities in the Amazon biome (including both lowland forests and Andean regions), and found that elevation was the primary driver of ß-diversity among those communities. Presley et al .…”

“…Abiotic factors driving patterns of bat community diversity levels Gorresen and Willig (2004) and Gorresen et al (2005) examined associations between phyllostomid bat community attributes and landscape structure (including deforested and fragmented forest habitats) in the Upper Parana Atlantic Forest region of eastern Paraguay (the only Paraguayan ecoregion not considered in the present study), and found scale dependence in those associations. Recently, Carvalho et al (2022) compiled an extensive literature-based evaluation of bat community diversity across multiple communities in the Amazon biome (including both lowland forests and Andean regions), and found that elevation was the primary driver of ß-diversity among those communities. Presley et al (2009: 781) concluded an analysis of Para guayan bat communities along multiple ordination axes with the comment that "analysis … along defined gradients (e.g., latitude, elevation and depth)" could provide complementary insights into elements of metacommunity structure.…”

Five decades of biogeography: A view from the Journal of Biogeography

“…We will book‐end the year with a reflection on Alfred Russel Wallace, who would celebrate his 200th birthday on 08th January 2023, by Ali and Heaney (2022) and a celebration of the 60th anniversary of MacArthur and Wilson (1963) in December via a special issue on functional island biogeography. Also in January we celebrate the contributions of early career biogeographers (Carvalho et al, 2022; Vasconcelos et al, 2021; Windsor et al, 2022; see Dawson et al, 2023), and then throughout the year we will publish Perspectives by senior biogeographers who we asked to look for inspiration in the aforementioned historical ‘top 50’ collections to set the scene for future years. We also solicited contributions on New Techniques and the Future of Biogeography , which will be published throughout the year and provide a small sampling of ongoing developments.…”

Journal of Biogeography Innovation Awards, 2023

“…Thus, we are delighted to introduce a new Virtual Issue that does all these things, collating papers submitted in response to the announcement of the JBI Innovation Awards , a venue for manuscripts first‐authored by early career researchers that encourages new ideas and perspectives in the discipline. The virtual issue begins with the inaugural (Carvalho et al, 2023; Vasconcelos et al, 2023; Windsor et al, 2023) and most recent (Korábek et al, 2022; Schrader et al, 2023) papers and will continue to grow each year. The manuscripts were considered using JBI's standard editorial and peer review processes and were additionally ranked in terms of the originality of their ideas, identification of a gap in knowledge, and impact of findings.…”
