Data from: The effects of human-altered habitat spatial pattern on frugivory and seed dispersal: a global meta-analysis

Eliana Cazetta & Lenore Fahrig
Seed dispersal by frugivorous animals is important for plant mobility, regeneration, and persistence. Human-caused landscape change is thought to disrupt seed dispersal, but evidence is scarce. We performed a comprehensive meta-analysis on the effects of habitat spatial pattern on frugivory and seed dispersal. We found 233 effects from 71 studies. At a patch or local scale, altered habitat spatial pattern was measured as declining patch size, increasing patch isolation, or habitat edge (vs. interior). At...

Data from: Environmental constraints on the compositional and phylogenetic beta-diversity of tropical forest snake assemblages

Mario R. Moura, Henrique C. Costa, Antonio J. S. Argôlo & Walter Jetz
The ongoing biodiversity crisis increases the importance and urgency of studies addressing the role of environmental variation on the composition and evolutionary history of species assemblages, but especially the tropics and ectotherms remain understudied. In regions with rainy summers, coexistence of ectothermic species may be determined by the partitioning of the climatic niche, since ectotherms can rely on water availability and thermoregulatory behaviour to buffer constraints along their climatic niche. Conversely, ectotherms facing dry summers...

Data from: Compensatory dynamics maintain bird phylogenetic diversity in fragmented tropical landscapes

José Carlos Morante Filho, Víctor Arroyo-Rodríguez, Edyla R. Andrade, Bráulio A. Santos, Eliana Cazetta, Deborah Faria & Edyla R. De Andrade
1.Tropical forest loss can drive the extinction of forest-dependent species. Yet, non-forest species can proliferate in deforested landscapes, thus enabling community-level attributes (e.g., total abundance and richness) to be maintained in the remaining forest patches. Such compensatory dynamics have been, however, poorly investigated regarding the phylogenetic dimension of species diversity. Here, we assessed whether compensatory dynamics can stabilize the phylogenetic richness, divergence and structure of bird communities in response to forest loss in two regions...

Data from: Local extinctions of obligate frugivores and patch size reduction disrupt the structure of seed dispersal networks

Jamille De Assis Bomfim, , Carlos A. Peres, Gustavo Carvalho & Eliana Cazetta
A central problem in ecology is to understand how human impacts affect plant-animal interactions that lead to effective seed dispersal services for plant communities. Seed dispersal services are the outcome of plant-frugivore interactions that often form local networks of interacting species. Recent work has shown that some frugivorous bird species are more critical to network organization than others. Here, we explore how patch size and the potential local extinctions of obligate frugivorous birds affect the...

Data from: Cryptic phylogeographic history sheds light on the generation of species diversity in sky-island mountains

Kai He, Eliécer E. Gutiérrez, Neander M. Heming, Klaus-Peter Koepfli, Tao Wan, Shuiwang He, Jin Wei, Shao-Ying Liu & Xue-Long Jiang
Biodiversity hotspots should be given high priority for conservation under the situation of global climate change. The sky islands in southwestern China are characterized by extraordinarily high species diversity and are among one of the world’s top biodiversity hotspots. However, neither the actual species diversity in this region or mechanisms generating this diversity are well explored. Here, we report on the phylogeographic analysis of the long-tailed mole (Scaptonyx fusicaudus), a semi-fossorial mammal that inhabits the...

Data from: Genetic differentiation in the stingless bee, Scaptotrigona xanthotricha Moure, 1950 (Apidae, Meliponini): a species with wide geographic distribution in the Atlantic rainforest

Olívia M. P. Duarte, Fernanda A. Gaiotto & Marco A. Costa
Stingless bees are important pollinators that are severely threatened by anthropic interference, resulting in a strong population decline. Scaptotrigona xanthotricha has a wide distribution in the Atlantic Rainforest, ranging from the northeastern state of Bahia to Santa Catarina in southern Brazil. To understand the genetic structure of S. xanthotricha, 12 species-specific microsatellite loci were analyzed in 42 colonies sampled throughout the species range. The results indicated 5 distinct clusters throughout the sampled area with high...

Data from: Effects of forest degradation on Amazonian ferns in a land-bridge island system as revealed by non-specialist inventories

Danielle Storck-Tonon, Gabriela Zuquim, Maíra Benchimol, Rafael Tonon & Carlos Peres
Background: Tropical deforestation and degradation worldwide have rapidly outpaced biodiversity field sampling. No study to date has assessed the effects of insular habitats induced by hydroelectric dams on Amazonian understorey plants. Fern community responses to anthropogenic effects on tropical forest islands can be efficiently revealed through simple and cheap, yet informative protocols that can be applied by non-specialists. Aims: This study seeks to both understand the drivers of fern and lycophyte assemblages on forest islands...

Data from: The impact of anthropogenic disturbances on the genetic diversity of terrestrial species: a global meta-analysis

Eliana Cazetta
Human activities are primarily responsible for habitat loss and changes in natural environments around the world. It has been suggested that populations inhabiting human-modified landscapes are subject to reduced gene flow, inbreeding depression, and loss of alleles due to genetic drift. However, empirical evidence shows contradictory effects of anthropogenic disturbances on the genetic diversity of terrestrial species. We performed a meta-analysis of 61 studies that compared the genetic diversity of plant and/or animal populations in...

Functional diversity and trait filtering of insectivorous bats on forest islands created by an Amazonian mega dam

Guthieri T. Colombo, Raffaello Di Ponzio, Maíra Benchimol, Carlos A. Peres & Paulo Estefano D. Bobrowiec
1. Mega dams in lowland tropical forests often create large archipelagos, leading to biodiversity decay and disruption of ecosystem functioning in remnant habitat islands. 2. We investigated the functional diversity and functional trait filtering of aerial insectivorous bats in both insular forest patches created by a vast ~30-yr-old hydropower reservoir and the adjacent mainland continuous forest in Central Amazonia. 3. Bats were surveyed using passive bat recorders across 34 forest sites. Based on a set...

Data from: Landscape Corridors (LSCorridors): a new software package for modeling ecological corridors based on landscape patterns and species requirements

John Wesley Ribeiro, Juliana Silveira Dos Santos, Pavel Dodonov, Felipe Martello, Bernardo Brandão Niebuhr & Milton Cezar Ribeiro
1.Maintaining connectivity is one of the main challenges for biodiversity conservation worldwide. Ecological corridors are important to maintain landscape connectivity, but their efficiency depends on landscape patterns and species responses at different spatial extents and landscape contexts. 2.We developed a new ecologically oriented free software package, LandScape Corridors (LSCorridors), to improve ecological corridor design by considering biodiversity responses to landscape attributes at a variety of spatial extents. LSCorridors considers stochastic variation, species perception and landscape...

Functional biogeography of Neotropical moist forests: trait-climate relationships and assembly patterns of tree communities

Bruno Pinho, Marcelo Tabarelli, Cajo Ter Braak, S. J. Wright, Victor Arroyo-Rodriguez, Maíra Benchimol, Bettina Engelbrecht, Simon Pierce, Peter Hietz, Bráulio Santos, Carlos Peres, Sandra Müller, Ian Wright, Frans Bongers, Madelon Lohbeck, Ülo Niinemets, Martijn Slot, Steven Jansen, Davi Jamelli, Renato Augusto Ferreira De Lima, Nathan Swenson, Richard Condit, Jos Barlow, Ferry Slik, Manuel Hernández-Ruedas … & Felipe Melo
Aim: Here we examine the functional profile of regional tree species pools across the latitudinal distribution of Neotropical moist forests, and test trait-climate relationships among local communities. We expected opportunistic strategies (acquisitive traits, small seeds) to be overrepresented in species pools further from the equator due to long-term instability, but also in terms of abundance in local communities in currently wetter, warmer and more seasonal climates. Location: Neotropics. Time period: Recent. Major taxa studied: Trees....

Decline of the brown-throated sloth (Bradypus variegatus Schinz, 1825) in an Atlantic Forest protected area

Gabriel Lopes, Gabriel Penido, Neander Heming & Luisa Diele-Viegas
Estimates on demographic parameters altogether with social factors are integral and can be very useful to assess the risks that a population may face in the future. Rescue operations may provide a unique opportunity to gather data on individuals of an area and thus provide population information. Animal rescue data provided by the Rio de Janeiro Botanical Garden fauna team were used to understand the structure of a population of Bradypus variegatus in an urban...

The cruises are EASIZ II (PS 48/ANT XV-3), ANDEEP I (PS 61/ANT XIX-3), ANDEEP II (PS 67/ANTXXII-3), and ANDEEP III (PS 67/ANTXXII-4). The samples related to the present file were all collected using an epibenthic sledge, described by (Brandt & Barthel, 1995; Brenke, 2005, see...

Humpback whale song comparison for the Atlantic sector of the Southern Ocean

Elena Schall, Divna Djokic, Erin Ross-Marsh, Javier Oña, Judith Denkinger, Julio Ernesto Baumgarten, Linilson Rodrigues Padovese, Marcos R. Rossi-Santos, Maria Isabel Carvalho Goncalves, Renata Santoro Sousa-Lima, Rodrigo Hucke-Gaete, Simon Elwen, Susannah Buchan, Tess Gridley & Ilse Van Opzeeland
The results of comparative song analyses between the ASSO and the Ecuadorian and Brazilian breeding populations and recordings from the Chilean, South African and Namibian migration routes revealed that individuals from at least three humpback whale breeding populations most likely migrate to shared feeding grounds in the ASSO. Humpback whales from different populations potentially mix at different times (i.e., years) at feeding hotspots of variable locations.

Data from: A new species of Allophryne (Anura: Allophrynidae) from the Atlantic Rain Forest biome of eastern Brazil

Ulisses Caramaschi, Victor G. D. Orrico, Julián Faivovich, Iuri R. Dias & Mirco Solé
A new species of the genus Allophryne is described and, in contrast to its congeners that occur in the Amazon Basin, is based on specimens obtained in Uruçuca, State of Bahia, in the Atlantic Rain Forest of eastern Brazil. Allophryne relicta sp. nov. is characterized by a medium body size for the genus (snout–vent length range 19.9–21.9 mm in males); large head (head width about 35% of SVL); large, red-orange eyes, with a large black...

Data from: Dynamics of coral reef benthic assemblages of the Abrolhos Bank, eastern Brazil: inferences on natural and anthropogenic drivers

Ronaldo B. Francini-Filho, Ericka O. C. Coni, Pedro M. Meirelles, Gilberto M. Amado-Filho, Fabiano L. Thompson, Guilherme H. Pereira-Filho, Alex C. Bastos, Douglas P. Abrantes, Camilo M. Ferreira, Fernando Z. Gibran, Arthur Z. Güth, Paulo Y. G. Sumida, Nara L. Oliveira, Les Kaufman, Carolina V. Minte-Vera & Rodrigo L. Moura
The Abrolhos Bank (eastern Brazil) encompasses the largest and richest coral reefs of the South Atlantic. Coral reef benthic assemblages of the region were monitored from 2003 to 2008. Two habitats (pinnacles’ tops and walls) were sampled per site with 3-10 sites sampled within different reef areas. Different methodologies were applied in two distinct sampling periods: 2003-2005 and 2006-2008. Spatial coverage and taxonomic resolution were lower in the former than in the latter period. Benthic...

Yves Basset, Lukas Cizek, Philippe Cuénoud, Raphael K. Didham, Vojtech Novotny, Frode Ødegaard, Tomas Roslin, Alexey K. Tishechkin, Jürgen Schmidl, Neville N. Winchester, David W. Roubik, Henri-Pierre Aberlenc, Johannes Bail, Héctor Barrios, Jonathan R. Bridle, Gabriela Castaño-Meneses, Bruno Corbara, Gianfranco Curletti, Wesley Duarte Da Rocha, Domir De Bakker, Jacques H.C. Delabie, Alain Dejean, Laura L. Fagan, Andreas Floren, Roger L. Kitching … & Jacques H. C. Delabie
Quantifying the spatio-temporal distribution of arthropods in tropical rainforests represents a first step towards scrutinizing the global distribution of biodiversity on Earth. To date most studies have focused on narrow taxonomic groups or lack a design that allows partitioning of the components of diversity. Here, we consider an exceptionally large dataset (113,952 individuals representing 5,858 species), obtained from the San Lorenzo forest in Panama, where the phylogenetic breadth of arthropod taxa was surveyed using 14...

Disentangling drivers of small mammal diversity in a highly fragmented forest system

Noé De La Sancha, Renan Maestri, Ricardo Bovendorp & Christopher Higgins
The Atlantic Forest is the second most diverse forest system in South America and only a fraction of its original distribution remains. In this study, we aim to use robust datasets of small mammals along the entire forest system to disentangle the main drivers for diversity along this gradient. More specifically we aim to disentangle if deforestation (recent), biogeographical variables, including 19 bioclimatic variables (historic), or historical trapping bias best describe patterns of taxonomic, functional,...

Tropical forest loss drives divergent patterns in functional diversity of forest and non-forest birds

Maísa Assano Matuoka, Maíra Benchimol & José Carlos Morante-Filho
Tropical forests have been facing high rates of deforestation driven by multiple anthropogenic disturbances, with severe consequences for biodiversity. However, the understanding of such effects on functional diversity is still limited in tropical regions, especially considering different ecological groups responses. Here we evaluated the functional responses of birds to forest loss at the threatened Brazilian Atlantic forest, considering the complete assemblage, and both forest-dependent and non-forest-dependent species. Birds were surveyed in 40 forest sites with...

Amphbian larvae survey at Emas National Park, Brazil (2012/2013, 2014/2015, 2017/2018)

Fausto Nomura, Ingrid Beatriz Ferreira Paixão & Gabriela Alves-Ferreira
Multiple factors contribute to explaining the composition and structure of communities and the niche is still the most used theory to describe how organisms interact with such factors to generate biological communities’ patterns. Both biotic and abiotic aspects of the environment along with the geographic space interact in complex ways with the behavior and physiological tolerance of organisms to structure a community. In this study, we tested the potential effects of the environment and space...

Natural history predicts patterns of thermal vulnerability in amphibians from the Atlantic rainforest of Brazil_supporting information

Leildo Machado Carilo Filho
In the Brazilian Atlantic Rainforest (AF), amphibians (625 species) face habitat degradation leading to stressful thermal conditions that constrain animal activity (e.g. foraging, reproduction). Data on thermal ecology for these species is still scarce. We tested the hypothesis that environmental occupation affects the thermal tolerance of amphibian species more than their phylogenetic relationships. We evaluated patterns of thermal tolerance of 47 amphibian species by assessing critical thermal maxima and warming tolerances, relating these variables with...

Data from: Widespread forest vertebrate extinctions induced by a mega hydroelectric dam in lowland Amazonia

Maíra Benchimol & Carlos A. Peres
Mega hydropower projects in tropical forests pose a major emergent threat to terrestrial and freshwater biodiversity worldwide. Despite the unprecedented number of existing, under-construction and planned hydroelectric dams in lowland tropical forests, long-term effects on biodiversity have yet to be evaluated. We examine how medium and large-bodied assemblages of terrestrial and arboreal vertebrates (including 35 mammal, bird and tortoise species) responded to the drastic 26-year post-isolation history of archipelagic alteration in landscape structure and habitat...

Data from: Arthropod diversity in a tropical forest

Yves Basset, Lukas Cizek, Philippe Cuénoud, Raphael K. Didham, François Guilhaumon, Olivier Missa, Vojtech Novotny, Frode Ødegaard, Tomas Roslin, Jürgen Schmidl, Alexey K. Tishechkin, Neville N. Winchester, David W. Roubik, Henri-Pierre Aberlenc, Johannes Bail, Héctor Barrios, Jon R. Bridle, Gabriela Castaño-Meneses, Bruno Corbara, Gianfranco Curletti, Wesley Duarte Da Rocha, Domir De Bakker, Jacques H. C. Delabie, Alain Dejean, Laura L. Fagan … & Maurice Leponce
Most eukaryotic organisms are arthropods. Yet, their diversity in rich terrestrial ecosystems is still unknown. Here we produce tangible estimates of the total species richness of arthropods in a tropical rainforest. Using a comprehensive range of structured protocols, we sampled the phylogenetic breadth of arthropod taxa from the soil to the forest canopy in the San Lorenzo forest, Panama. We collected 6,144 arthropod species from 0.48 ha and extrapolated total species richness to larger areas...

Data from: Habitat use of the ocelot (Leopardus pardalis) in Brazilian Amazon

Bingxin Wang, Daniel G. Rocha, Mark I. Abrahams, André P. Antunes, Hugo C. M. Costa, André Luis Sousa Gonçalves, Wilson Roberto Spironello, Milton José De Paula, Carlos A. Peres, Juarez Pezzuti, Emiliano Ramalho, Marcelo Lima Reis, , Fabio Rohe, David W. Macdonald & Cedric Kai Wei Tan
Amazonia forest plays a major role in providing ecosystem services for human and sanctuaries for wildlife. However, ongoing deforestation and habitat fragmentation in the Brazilian Amazon has threatened both. The ocelot is an ecologically important mesopredator and a potential conservation ambassador species, yet there are no previous studies on its habitat preference and spatial patterns in this biome. From 2010 to 2017, twelve sites were surveyed, totaling 899 camera trap stations, the largest known dataset...

Data from: Patterns and predictors of β-diversity in the fragmented Brazilian Atlantic forest: a multiscale analysis of forest specialist and generalist birds

José Carlos Morante-Filho, Victor Arroyo-Rodríguez & Deborah Faria
1. Biodiversity maintenance in human-altered landscapes (HALs) depends on the species turnover among localities, but the patterns and determinants of β-diversity in HALs are poorly known. In fact, declines, increases, and neutral shifts in β-diversity have all been documented, depending on the landscape, ecological group and spatial scale of analysis. 2. We shed some light on this controversy by assessing the patterns and predictors of bird β-diversity across multiple spatial scales considering forest specialist and...
