Cryptic relatedness is a confounding factor in genetic diversity and genetic association studies. Development of strategies to reduce cryptic relatedness in a sample is a crucial step for downstream genetic analyzes. The present study uses a node selection algorithm, based on network degrees of centrality, to evaluate its applicability and impact on evaluation of genetic diversity and population stratification. 1,036 Guzerá (Bos indicus) females were genotyped using Illumina Bovine SNP50 v2 BeadChip. Four strategies were...

Data from: Disentangling the pathways of land use impacts on the functional structure of fish assemblages in Amazon streams

Rafael P. Leitão, Jansen Zuanon, David Mouillot, Cecília G. Leal, Robert M. Hughes, Philip R. Kaufmann, Sébastien Villéger, Paulo S. Pompeu, Daniele Kasper, Felipe R. De Paula, Silvio F. B. Ferraz & Toby A. Gardner
Agricultural land use is a primary driver of environmental impacts on streams. However, the causal processes that shape these impacts operate through multiple pathways and at several spatial scales. This complexity undermines the development of more effective management approaches, and illustrates the need for more in-depth studies to assess the mechanisms that determine changes in stream biodiversity. Here we present results of the most comprehensive multi-scale assessment of the biological condition of streams in the...

Data from: Assessing the conservation value of secondary savanna for large mammals in the Brazilian Cerrado

Guilherme B. Ferreira, Jorge A. Ahumada, Marcelo J. R. Oliveira, Fernando F. De Pinho, Izabela M. Barata, Chris Carbone & Ben Collen
Debate about the conservation value of secondary habitats has tended to focus on tropical forests, increasingly recognizing the role of secondary forests for biodiversity conservation. However, there remains a lack of information about the conservation value of secondary savannas. Here, we conducted a camera trap survey to assess the effect of secondary vegetation on large mammals in a Brazilian Cerrado protected area, using a single-season occupancy framework to investigate the response of individual species (species-level...

Data from: Habitat attributes similarities reduce impacts of land-use conversion on seed removal

Ananza M. Rabello, Catherine L. Parr, Antônio C.M. Queiroz, Danielle L. Braga, Graziele S. Santiago & Carla R. Ribas
Changes in land use strongly influence habitat attributes (e.g., herbaceous ground cover and tree richness) and can consequently affect ecological functions. Most studies have focused on the response of these ecological functions to land-use changes within only a single vegetation type. These studies have often focused solely on agricultural conversion of forests, making it nearly impossible to draw general conclusions across other vegetation types or with other land use changes (e.g., afforestation). We examined the...

Data from: Niche conservatism and the invasive potential of the wild boar

Lilian Patricia Sales, Bruno R. Ribeiro, Matt Warrington Hayward, Adriano P. Paglia, Marcelo Passamani & Rafael Loyola
1.Niche conservatism, i.e. the retention of a species’ fundamental niche through evolutionary time, is cornerstone for biological invasion assessments. The fact that species tend to maintain their original climate niche allows predictive maps of invasion risk to anticipate potential invadable areas. Unraveling the mechanisms driving niche shifts can shed light on the management of invasive species. 2.Here, we assessed niche shifts in one of the world's worst invasive species: the wild boar Sus scrofa. We...

Data from: Safety and immunogenicity of the Na-GST-1 hookworm vaccine in Brazilian and American adults

Diemert, Doreen Campbell, Frederico Talles, Guangzhao Li, Janaína Freire, Jeffrey Bethony, Jill Brelsford, Jin Peng, Maria Flávia Gazzinelli, Maria Victoria Periago, Maria Elena Bottazzi, Martin Enk, Peter Hotez, Robert Hamilton, Rodrigo Correa-Oliveira, Shannon Grahek & Vanderson Valente
Necator americanus Glutathione-S-Transferase-1 (Na-GST-1) plays a role in the digestion of host hemoglobin by adult N. americanus hookworms. Vaccination of laboratory animals with recombinant Na-GST-1 is associated with significant protection from challenge infection. Recombinant Na-GST-1 was expressed in Pichia pastoris and adsorbed to aluminum hydroxide adjuvant (Alhydrogel) according to current Good Manufacturing Practice. Two Phase 1 trials were conducted in 142 healthy adult volunteers in the United States and Brazil, first in hookworm-naïve individuals and...

Data from: Is environmental legislation conserving tropical stream faunas? a large-scale assessment of local, riparian and catchment-scale influences on Amazonian stream fish

Cecília G. Leal, Jos Barlow, Toby Gardner, Robert M. Hughes, Rafael P. Leitão, Ralph Mac Nally, Philip R. Kaufmann, Silvio F. B. Ferraz, Jansen Zuanon, Felipe R. De Paula, Joice Ferreira, James R. Thomson, Gareth D. Lennox, Eurizângela P. Dary, Cristhiana P. Röpke, Paulo S. Pompeu & Toby A. Gardner
1.Agricultural expansion and intensification are major threats to tropical biodiversity. In addition to the direct removal of native vegetation, agricultural expansion often elicits other human-induced disturbances, many of which are poorly addressed by existing environmental legislation and conservation programmes. This is particularly true for tropical freshwater systems, where there is considerable uncertainty about whether a legislative focus on protecting riparian vegetation is sufficient to conserve stream fauna. 2.To assess the extent to which stream fish...

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: Factors influencing ocelot occupancy in Brazilian Atlantic Forest reserves

Rodrigo Lima Massara, Ana Maria De Oliveira Paschoal, Larissa Lynn Bailey, , André Hirsch, Adriano Garcia Chiarello & Paul F. Doherty
Over 80% of Atlantic Forest remnants are <50 ha and protected areas are embedded in a matrix dominated by human activities, undermining the long-term persistence of carnivores. The ocelot (Leopardus pardalis) is an opportunistic species, but little is known about its tolerance to habitat alterations and the influence of other species on its occupancy in Atlantic Forest remnants. We used camera traps to assess ocelot occupancy in protected areas of Atlantic Forest in southeastern Brazil....
