Data from: Individual and interactive effects of chronic anthropogenic disturbance and rainfall on taxonomic, functional and phylogenetic composition and diversity of extrafloral nectary-bearing plants in Brazilian Caatinga

Xavier Arnan, Carlos Silva, Daniela Reis, Fernanda Oliveira, Talita Câmara, Elâine Ribeiro, Alan Andersen & Inara Leal
Chronic anthropogenic disturbance (CAD) and climate change represent two of the major threats to biodiversity globally, but their combined effects are not well understood. Here we investigate the individual and interactive effects of increasing CAD and decreasing rainfall on the composition and taxonomic (TD), functional (FD) and phylogenetic diversity (PD) of plants possessing extrafloral nectaries (EFNs) in semi-arid Brazilian Caatinga. EFNs attract ants that protect plants against insect herbivore attack and are extremely prevalent in...

Foraging networks and social tolerance in a cooperatively breeding primate (Callithrix jacchus)

María Fernanda De La Fuente, Cédric Sueur, Paul Garber, Júlio César Bicca-Marques, Antonio Souto & Nicola Schiel
Within-group competition over food resources can be a major cost of social living. In the wild, foragers are confronted with social (e.g. hierarchical rank) and ecological (e.g. food availability and distribution) challenges that affect their foraging decisions and feeding success. Exhibiting prosocial behaviors, such as tolerance at feeding sites, can benefit group members by developing affiliative social relationships, enhancing access to resources and maximizing fitness. We examined social tolerance at feeding sites in Callithrix jacchus,...

Managed logging negatively affects the density and abundance of some dry forest specialist bird species of northeastern Brazil

Jonathan Ribeiro, Flor Ias-Casas, Weber Silva & Luciano Naka
The Caatinga, the largest region of seasonally dry tropical forest in the Neotropics, suffers high rates of deforestation and habitat degradation, mostly due to wood extraction. As an alternative to illegal logging, governments have looked at more sustainable management schemes, allowing natural regeneration after logging through relatively long (~ 25-yr) harvest rotations. We investigated the impacts of forest management at a 1,700-ha privately-owned area located at the Araripe Plateau, in the semi-arid interior of northeastern...

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....

Data from: Putting vascular epiphytes on the traits map

Epiphyte trait data for the paper Hietz et al. 2021 Putting vascular epiphytes on the traits map. Journal of Ecology Plant functional traits impact the fitness and environmental niche of plants. Major plant functional types have been characterized by their trait spectrum, and the environmental and phylogenetic imprints on traits have advanced several ecological fields. Yet very few trait data on epiphytes, which represent almost 10% of vascular plants, are available. We collated >80,000 mostly...

Deep reefs are not refugium for shallow-water fish communities in the southwestern Atlantic

Aline Medeiros, Beatrice Ferreira, Fredy Alvarado, Ricardo Betancur-R, Marcelo Soares & Bráulio Santos
1. The deep reef refugia hypothesis (DRRH) predicts that deep reef ecosystems may act as refugium for the biota of disturbed shallow waters. Because deep reefs are amongst the most understudied habitats on Earth, formal tests of the DRRH remain scarce. If the DRRH is valid at the community level, the diversity of species, functions and lineages of fish communities of shallow reefs should be encapsulated in deep reefs. 2. We tested the DRRH by...

Data from: The evolution of polymorphism in the warning coloration of the Amazonian poison frog Adelphobates galactonotus

Diana Rojas, Paolo Momigliano, Albertina Pimentel Lima, Pedro Ivo Simões, Rachel Y. Dudaniec, Teresa C. S. Avila-Pires, Marinus S. Hoogmoed, Youszef O. C. Bitar, Igor Luis Kaefer, Adolfo Amézquita & Adam Stow
While intraspecific variation in aposematic signals can be selected for by different predatory responses, their evolution is also contingent on other processes shaping genetic variation. We evaluate the relative contributions of selection, geographic isolation and random genetic drift to the evolution of aposematic color polymorphism in the poison frog Adelphobates galactonotus, distributed throughout eastern Brazilian Amazonia. Dorsal coloration was measured for 111 individuals and genetic data were obtained from 220 individuals at two mitochondrial genes...

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

Bo Dalsgaard, Pietro Maruyama, Jesper Sonne, Katrine Hansen, Thais Zanata, Stefan Abrahamczyk, Ruben Alarcon, Andréa Araujo, Francielle Araújo, Silvana Buzato, Edgar Chávez-González, Aline Coelho, Pete Cotton, Román Díaz-Valenzuela, Maria Dufke, Paula Enríquez, Manoel Martins Dias Filho, Erich Fischer, Glauco Kohler, Carlos Lara, Flor Maria Las-Casas, Liliana Rosero Lasprilla, Adriana Machado, Caio Machado, Maria Maglianesi … & Ana M. 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...

Drought-induced reductions in plant defenses

Talita Câmara, Daniela Queiroz De Assis Reis, Xavier Arnan, Fernanda Maria Pereira De Oliveira, Emilia Cristina Pereira De Arruda & Inara Roberta Leal
Extrafloral nectaries (EFNs) are anti-herbivory defense-related glands. We measured morphological and anatomical EFN traits in Pityrocarpa moniliformis trees along a rainfall gradient in Caatinga dry forest. We observed a reduction in structural EFN traits as rainfall decreased. We conclude that this reduction is a cost-saving strategy, probably mediated by ants.

Data for: Phylogenomic analyses reveal non-monophyly of the antbird genera Herpsilochmus and Sakesphorus (Thamnophilidae), with description of a new genus for Herpsilochmus sellowi

Gustavo Bravo, Bret Whitney, Ricardo Belmonte-Lopes, Marcos Bornschein, Natalia Aristizabal, Renata Beco, Jaqueline Battilana, Luciano Naka, Alexandre Aleixo, Marcio Pie, Luis Silveira, Elizabeth Derryberry & Robb Brumfield
The family Thamnophilidae is a species-rich Neotropical radiation of passerine birds. Current classification of its 235 species is mostly based on morphological similarities, but recent studies integrating comprehensive phenotypic and phylogenetic data have redefined taxonomic limits of several taxa. Here, we assess generic relationships of Herpsilochmus, Sakesphorus, Thamnophilus, Biatas, and Dysithamnus using DNA sequences from the mitochondrion, nuclear exons, and ultraconserved elements (UCEs), with further attention to interspecific relationships within Herpsilochmus. We show that Herpsilochmus...
