Data from: Unravelling seed dispersal through fragmented landscapes: frugivore species operate unevenly as mobile links

Juan P. González-Varo, Carolina Carvalho, Juan M. Arroyo, Pedro Jordano & Carolina S. Carvalho
Seed dispersal constitutes a pivotal process in an increasingly fragmented world, promoting population connectivity, colonization and range shifts in plants. Unveiling how multiple frugivore species disperse seeds through fragmented landscapes, operating as mobile links, has remained elusive owing to methodological constraints for monitoring seed dispersal events. We combine for the first time DNA barcoding and DNA microsatellites to identify, respectively, the frugivore species and the source trees of animal-dispersed seeds in forest and matrix of...

Data from: Evolution and conservation of Characidium sex chromosomes

Ricardo Utsunomia, Priscilla C. Scacchetti, Miguel Hermida, Raquel Fernández-Cebrián, Xoana Taboada, Carlos Fernandez, Michaël Bekaert, Natalia J. Mendes, Diego Robledo, Judith E. Mank, John B. Taggart, Claudio Oliveira, Fausto Foresti & Paulino Martínez
Fish species exhibit substantial variation in the degree of genetic differentiation between sex chromosome pairs, and therefore offer the opportunity to study the full range of sex chromosome evolution. We used restriction-site associated DNA sequencing (RAD-seq) to study the sex chromosomes of Characidium gomesi, a species with conspicuous heteromorphic ZW/ZZ sex chromosomes. We screened 9863 single-nucleotide polymorphisms (SNPs), corresponding to ~1 marker/100 kb distributed across the genome for sex-linked variation. With this data set, we...

Data from: The role of the endemic and critically endangered Colorful Puffleg Eriocnemis mirabilis in plant-hummingbird networks of the Colombian Andes

Mónica B. Ramírez-Burbano, F. Gary Stiles, Catalina González, Felipe W. Amorim, Bo Dalsgaard, Pietro K. Maruyama. & Pietro K. Maruyama
Ecological network approaches may contribute to conservation practices by quantifying within-community importance of species. In mutualistic plant-pollinator systems, such networks reflect potential pollination of the plants and a considerable portion of the energy consumption by the pollinators, two key components for each party. Here, we used two different sampling approaches to describe mutualistic plant-hummingbird networks from a cloud forest in the Colombian Western Andes, home to the Colorful Puffleg Eriocnemis mirabilis, an endemic and critically...

Data from: Land cover and forest connectivity alter the interactions among host, pathogen and skin microbiome

C. Guilherme Becker, Ana V. Longo, Célio F.B. Haddad, Kelly R. Zamudio & C. F. B. Haddad
Deforestation has detrimental consequences on biodiversity, affecting species interactions at multiple scales. The associations among vertebrates, pathogens and their commensal/symbiotic microbial communities (i.e. microbiomes) have important downstream effects for biodiversity conservation, yet we know little about how deforestation contributes to changes in host microbial diversity and pathogen abundance. Here, we tested the effects of landcover, forest connectivity and infection by the chytrid fungus Batrachochytrium dendrobatidis (Bd) on amphibian skin bacterial diversity along deforestation gradients in...

Data from: Geographical and intrapopulation variation in the diet of a threatened marine predator, Pontoporia blainvillei (Cetacea)

Barbara Henning, Benilton De Sá Carvalho, Mathias Mistretta Pires, Manuela Bassoi, Juliana Marigo, Carolina Bertozzi & Márcio S. Araújo.
Diet variation can occur in geographically structured populations due to variation in prey availability. Within locations, diet may vary due to effects of season, sex, age, and individual. Nevertheless, these sources of variation are seldom considered together in dietary studies. Major efforts are underway to investigate population and ecological traits of marine organisms to set guidelines for conservation and management. Examining diet variation is a major concern when developing conservation guidelines for threatened species, especially...

Data from: Distribution and functionality of copy number variation across European cattle populations

Maulik Upadhyay, Vinicius H. Da Silva, Hendrik-Jan Megens, Marleen H. P. W. Visker, Paolo Ajmone-Marsan, Valentin A. Bâlteanu, Susana Dunner, Jose Fernando Garcia, Catarina Ginja, Juha Kantanen, Martien A.M. Groenen, Richard P.M.A. Crooijmans, Vinicus H. Da Silva, Martien A. M. Groenen & Richard P. M. A. Crooijmans
Copy number variation (CNV), which is characterized by large-scale losses or gains of DNA fragments, contributes significantly to genetic and phenotypic variation. Assessing CNV across different European cattle populations might reveal genetic changes responsible for phenotypic differences, which have accumulated throughout the domestication history of cattle as consequences of evolutionary forces that act upon them. To explore pattern of CNVs across European cattle, we genotyped 149 individuals, that represent different European regions, using the Illumina...

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...

Data from: Rediscovery of the enigmatic fungus-farming ant \"Mycetosoritis\" asper Mayr (Hymenoptera: Formicidae): Implications for taxonomy, phylogeny, and the evolution of agriculture in ants

Jeffrey Sosa-Calvo, Ana Ješovnik, Heraldo L. Vasconcelos, , Ted R. Schultz & Mauricio Bacci
We report the rediscovery of the exceedingly rarely collected and enigmatic fungus-farming ant species Mycetosoritis asper. Since the description of the type specimen in 1887, only four additional specimens are known to have been added to the world's insect collections. Its biology is entirely unknown and its phylogenetic position within the fungus-farming ants has remained puzzling due to its aberrant morphology. In 2014 we excavated and collected twenty-one colonies of M. asper in the Floresta...

Data from: Trading heat and hops for water: dehydration effects on locomotor performance, thermal limits, and thermoregulatory behavior of a terrestrial toad

Rodolfo C.O. Anderson, Denis V. Andrade & Rodolfo C. O. Anderson
Due to their highly permeable skin and ectothermy, terrestrial amphibians are challenged by compromises between water balance and body temperature regulation. The way in which such compromises are accommodated, under a range of temperatures and dehydration levels, impacts importantly the behavior and ecology of amphibians. Thus, using the terrestrial toad Rhinella schneideri as a model organism, the goals of this study were twofold. First, we determined how the thermal sensitivity of a centrally relevant trait—locomotion—was...

Data from: Highway widening and underpass effects on vertebrate road mortality

Giordano Ciocheti, Julia Camara De Assis, John Wesley Ribeiro & Milton Cezar Ribeiro
Road widening (a.k.a. road dualling) and the presence of mitigation structures may have opposing effects on the number of animal-vehicle collisions. Their influence in tropical areas is poorly quantified, and we know little about how modifications of road structure affect fauna roadkill and mitigation. We evaluated how road widening and proximity to a wildlife underpass affect roadkill of medium and large mammals, using roadkill records from before and after the widening of 150 km of...

Vertical profile data of light transmission in Atlantic forests along a disturbance gradient

S. Fauset, M.U. Gloor, M.A.P. Aidar, H.C. Freitas, N.M. Fyllas, C.A. Joly, M.A. Marabesi, A.L.C. Rochelle, A. Shenkin & S.A. Vieira
The data set contains vertical profiles of diffuse light transmittance measured within six forest plots in montane Atlantic forest, São Paulo state, Brazil. The plots measured include intact, previously logged and secondary forest in a large continuous forest block of the Serra do Mar State Park (Parque Estadual de Serra do Mar), and two forest fragments outside the park. In each plot 10 - 12 individual light profiles were recorded; the data set contains these...

Data from: Fishing-down within populations harms seed dispersal mutualism

Raul Costa-Pereira, Sandra Bibiana Correa & Mauro Galetti
Large fish are often the most effective seed dispersers, but they are also the preferred target for fisheries. We recently started to comprehend the detrimental impacts of the extirpation of large frugivorous fish species on natural forest regeneration, but we lack a general understanding of how intraspecific size-selective harvest affects fish–fruit mutualism. Our literature review demonstrated that large individuals within populations positively affect diverse aspects of seed dispersal, from consuming a higher diversity of seeds...

Data from: Biotransformation of labdane and halimane diterpenoids by two filamentous fungi strains

Afif F. Monteiro, Cláudia Seidl, Vanessa G.P. Severino, Carmen Lúcia Cardoso & Ian Castro-Gamboa
Biotransformation of natural products by filamentous fungi is a powerful and effective approach to achieve derivatives with valuable new chemical and biological properties. Despite diterpenoid substrates exhibit good susceptibility towards fungi enzymes, there have been no studies concerning the microbiological transformation of halimane-type diterpenoids up to now. In this work, we investigated the capability of Fusarium oxysporum (a fungus isolated from the rhizosphere of Senna spectabilis) and Myrothecium verrucaria (an endophyte) to transform halimane (1)...

Data from: Local and regional specialization in plant–pollinator networks

Daniel Wisbech Carstensen, Kristian Trøjelsgaard, Jeff Ollerton & Leonor Patricia C. Moraletto
Specialization of species is often studied in ecology but its quantification and meaning is disputed. More recently, ecological network analysis has been widely used as a tool to quantify specialization, but here its true meaning is also debated. However, irrespective of the tool used, the geographic scale at which specialization is measured remains central. Consequently, we use data sets of plant–pollinator networks from Brazil and the Canary Islands to explore specialization at local and regional...

Data from: A new subfamily classification of the Leguminosae based on a taxonomically comprehensive phylogeny

, Anne Bruneau, Nasim Azani, Marielle Babineau, Edeline Gagnon, Carole Sinou, Royce Steeves, Erin Zimmerman, C. Donovan Bailey, Lynsey Kovar, Madhugiri Nageswara-Rao, Hannah Banks, RuthP. Clark, Manuel De La Estrella, Peter Gasson, GeoffreyC. Kite, BenteB. Klitgaard, GwilymP. Lewis, Danilo Neves, Gerhard Prenner, María De Lourdes Rico-Arce, ArianeR. Barbosa, Maria Cristina López-Roberts, Luciano Paganucci De Queiroz, PétalaG. Ribeiro … & Tingshuang Yi
The classification of the legume family proposed here addresses the long-known non-monophyly of the traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supported monophyletic subfamilies. This new classification uses as its framework the most comprehensive phylogenetic analyses of legumes to date, based on plastid matK gene sequences, and including near-complete sampling of genera (698 of the currently recognised 765 genera) and ca. 20% (3696) of known species. The matK gene region has been the most...

Data from: Abandoned pastures cannot spontaneously recover the attributes of old-growth savannas

Mario G. B. Cava, Natashi A. L. Pilon, Milton Cezar Ribeiro & Giselda Durigan
1.Active restoration strategies have been recommended to recover Neotropical savannas in abandoned lands, but no studies have investigated the trajectories and speeds of spontaneous recovery for these systems. Research into the dynamics of degraded savannas is urgently needed to guide restoration decision-making. 2.We analysed the dynamics of secondary savannas in the Brazilian Cerrado by sampling 29 abandoned pastures (time since abandonment ranging from 3 to 25 years) and applying the space-for-time substitution method. We modelled...

Data from: Queen palm fruit selection and foraging techniques by squirrels in the Atlantic Forest

Briza Cristina Alves, Calebe Pereira Mendes & Milton Cezar Ribeiro.
Palm fruits are a significant resource for fauna worldwide, particularly in tropical regions. Such is the case for queen palm seeds (Syagrus romanzoffiana), which is a vital source of nutrients for the squirrel Guerlinguetus ingrami. This squirrel acts as seed predator, as well as seed disperser of this important palm for the frugivore community, but we don´t know how this squirrel select and manipulate the queen palm seeds. The objective of this study was to...

Data from: Genetic diversity and gene flow decline with elevation in montane mayflies

Nicholas R. Polato, Miranda M. Gray, Brian A. Gill, C. Guilherme Becker, K.L. Casner, Alex S. Flecker, Boris C. Kondratief, Andrea C. Encalada, N. LeRoy Poff, W. Chris Funk & Kelly R. Zamudio
Montane environments around the globe are biodiversity ‘hotspots’ and important reservoirs of genetic diversity. Montane species are also typically more vulnerable to environmental change than their low-elevation counterparts due to restricted ranges and dispersal limitations. Here we focus on two abundant congeneric mayflies (Baetis bicaudatus and B. tricaudatus) from montane streams over an elevation gradient spanning 1400 m. Using single-nucleotide polymorphism genotypes, we measured population diversity and vulnerability in these two species by: (i) describing...
