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: 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...

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...

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...

Benthic and benthopelagic Ostracoda from a wide depth range (189-6224 m) in the Atlantic Sector of the Southern Ocean

Simone Nunes Brandao, Hanieh Saeedi & Angelika Brandt
This dataset contains abundance (i.e., absolute number of speicmens/individuals) of ostracod genera collected during three cruises of the German Research Vessel Polarstern in the Atlantic Sector of the Southern Ocean. 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...

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

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....

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...
