Data from: Geographic shifts in the effects of habitat size on trophic structure and decomposition

Robin M. LeCraw, Gustavo Q. Romero & Diane S. Srivastava
Habitat size is known to affect community structure and ecosystem function, but few studies have examined the underlying mechanisms over sufficient size gradients or in enough geographic contexts to determine their generality. Our goal in this study was to determine if the relationship between habitat size and leaf decomposition varied across geographic sites, and which factors may be driving the differences. We conducted replicated observations in a coastal forest in Brazil, and in rainforests in...

Data from: Manifold influences of phylogenetic structure on a plant-herbivore network

Leonardo Lima Bergamini, Thomas M. Lewinsohn, Leonardo R. Jorge & Mário Almeida-Neto
Ecologists are increasingly aware of the interplay between evolutionary history and ecological processes in shaping current species interaction patterns. The inclusion of phylogenetic relationships in studies of species interaction networks has shown that closely related species commonly interact with sets of similar species. Notably, the degree of phylogenetic conservatism in antagonistic ecological interactions is frequently stronger among species at lower trophic levels than among those at higher trophic levels. One hypothesis that accounts for this...

Data from: Influence of plant-pollinator interactions on the assembly of plant and hummingbird communities

Marina Wolowski, Luísa G. Carvalheiro & Leandro Freitas
Understanding how ecological processes structure species assemblages is a central issue in community ecology. While the influence of plant–pollinator interactions on each other's evolution is well recognized, their role in the assembly of interdependent communities of plants and pollinators is still unclear. Using data from seven communities of hummingbirds and plants that they pollinate from two tropical rain forest types (lowland and montane), we evaluated phylogenetic relationships and signal of functional traits, over space and...

Data from: Restriction site associated DNA (RAD) for de novo sequencing and marker discovery in sugarcane borer, Diatraea saccharalis Fab. (Lepidoptera: Crambidae)

Vitor A.C. Pavinato, Gabriel R.A. Margarido, Asela J. Wijeratne, Saranga Wijeratne, Tea Meulia, Anete P. Souza, Andrew P. Michel, Maria I. Zucchi & V. A. C. Pavinato
We present the development of a genomic library using RADseq (restriction site associated DNA sequencing) protocol for marker discovery that can be applied on evolutionary studies of the sugarcane borer Diatraea saccharalis, an important South American insect pest. A RADtag protocol combined with Illumina paired-end sequencing allowed de novo discovery of 12 811 SNPs and a high-quality assembly of 122.8M paired-end reads from six individuals, representing 40 Gb of sequencing data. Approximately 1.7 Mb of...

Data from: Beyond neutral and forbidden links: morphological matches and the assembly of mutualistic hawkmoth-plant networks

Federico D. Sazatornil, Marcela Moré, Santiago Benitez-Vieyra, Andrea A. Cocucci, Ian J. Kitching, Boris O. Schlumpberger, Paulo E. Oliveira, Marlies Sazima & Felipe W. Amorim
A major challenge in evolutionary ecology is to understand how co-evolutionary processes shape patterns of interactions between species at community level. Pollination of flowers with long corolla tubes by long-tongued hawkmoths has been invoked as a showcase model of co-evolution. Recently, optimal foraging models have predicted that there might be a close association between mouthparts' length and the corolla depth of the visited flowers, thus favouring trait convergence and specialization at community level. Here, we...

Data from: Environmental constraints and call evolution in torrent dwelling frogs

Sandra Goutte, Alain Dubois, Samuel David Howard, Rafael Marquez, Jodi J. Rowley, J. Maximilian Dehling, Philippe Grandcolas, Xiong Rongchuan, Frédéric Legendre & Jodi J. L. Rowley
While acoustic signals are important for communication in many taxa, signal propagation is affected by environmental properties. Strong environmental constraints should drive call evolution, favoring signals with greater transmission distance and content integrity in a given calling habitat. Yet, few empirical studies have verified this prediction, possibly due to a shortcoming in habitat characterization, which is often too broad. Here we assess the potential impact of environmental constraints on the evolution of advertisement call in...

Data from: Temporal variation in the abundance and richness of foliage-dwelling ants mediated by extrafloral nectar

Ceres Belchior, Sebastián F. Sendoya & Kleber Del-Claro
Plants bearing extrafloral nectaries (EFNs) are common in the Brazilian cerrado savanna, where climatic conditions having marked seasonality influence arboreal ant fauna organization. These ant-plant interactions have rarely been studied at community level. Here, we tested whether: 1) EFN-bearing plants are more visited by ants than EFN-lacking plants; 2) ant visitation is higher in the rainy season than in dry season; 3) plants producing young leaves are more visited than those lacking young leaves in...

Data from: Contralateral noise stimulation delays P300 latency in school-aged children

Thalita Ubiali, Milaine Dominici Sanfins, Leticia Reis Borges & Maria Francisca Colella-Santos
Background and objective: The auditory cortex modulates auditory afferents through the olivocochlear system, which innervates the outer hair cells and the afferent neurons under the inner hair cells in the cochlea. Most of the studies that investigated the efferent activity in humans focused on evaluating the suppression of the otoacoustic emissions by stimulating the contralateral ear with noise, which assesses the activation of the medial olivocochlear bundle. The neurophysiology and the mechanisms involving efferent activity...

Data from: Genetic structure and diversity of populations of polyploid Tibouchina pulchra Cogn. (Melastomataceae) under different environmental conditions in extremes of an elevational gradient

Vinícius L. G. Brito, Gustavo M. Mori, Bianca B. Z. Vigna, Marianne Azevedo-Silva, Anete P. Souza & Marlies Sazima
The genetic structure and diversity of plants may change significantly in an elevational gradient because different elevations regulate different ecological conditions. Several factors may influence genetic variation, such as mutations, selection, genetic drift, and gene flow. The aim of the present study was to evaluate the genetic structure and diversity of populations of Tibouchina pulchra Cogn. (Melastomataceae) trees in two extremes of an elevational gradient experiencing different environmental conditions. Nine polymorphic microsatellite loci were used...

Data from: Arthropod distribution in a tropical rainforest: tackling a four dimensional puzzle

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...
