Data from: On the relative importance of CSR ecological strategies and integrative traits to explain species dominance at local scales

Bruno H. P. Rosado & Eduardo A. De Mattos
PLEASE NOTE, PART OF THESE DATA ARE ALSO REFERRED TO ANOTHER ARTICLE. PLEASE SEE http://dx.doi.org/10.1111/j.1654-1103.2009.01119.x FOR MORE INFORMATION. 1. Identifying ecological strategies based on functional traits has been one of the main focuses of studies on plant community assembly. Recently, an important and timely tool, “StrateFy”, has been proposed for detecting plant strategies across the globe according to the CSR scheme. The CSR scheme is undeniably efficient across scales, and distinct CSR strategies among species...

Data from: Ecological restoration success is higher for natural regeneration than for active restoration in tropical forests

Is active restoration the best approach to achieve ecological restoration success (the return to a reference condition, that is, old-growth forest) when compared to natural regeneration in tropical forests? Our meta-analysis of 133 studies demonstrated that natural regeneration surpasses active restoration in achieving tropical forest restoration success for all three biodiversity groups (plants, birds, and invertebrates) and five measures of vegetation structure (cover, density, litter, biomass, and height) tested. Restoration success for biodiversity and vegetation...

Data from: Intraspecific genetic structure, divergence and high rates of clonality in an amphi-Atlantic starfish

Alex Garcia-Cisneros, Crue Palacín, Carlos Renato R. Ventura, Barbara Feital, Paulo C. Paiva & Rocio Perez Portela
Intraspecific genetic diversity and divergence have a large influence on the adaption and evolutionary potential of species. The widely distributed starfish, Coscinasterias tenuispina, combines sexual reproduction with asexual reproduction via fission. Here we analyse the phylogeography of this starfish to reveal historical and contemporary processes driving its intraspecific genetic divergence. We further consider whether asexual reproduction is the most important method of propagation throughout the distribution range of this species. Our study included 326 individuals...

Data from: Fatty acid profiles of five farmed Brazilian freshwater fish species from different families

Bruna Leal Rodrigues, Anna Carolina Vilhena Da Cruz Silva Canto, Marion Pereira Da Costa, Flávio Alves Da Silva, Eliane Teixeira Mársico & Carlos Adam Conte-Junior
The proximate composition and fatty acid (FA) profiles of five Brazilian freshwater fish species, namely Brycon cephalus (BC), Cichla ocellaris (CO), Prochilodus lineatus (PL), Leporinus friderici (LF) and Pseudoplatystoma corruscans (PCO), were investigated. CO and LF exhibited the highest (p < 0.05) moisture content, as well as one of the lowest (p < 0.05) lipid values, whereas BC presented the lowest (p < 0.05) moisture and, alongside PL, the highest (p < 0.05) lipid content....

Data from: Does sex matter? Gender-specific responses to forest fragmentation in Neotropical bats

Ricardo Rocha, Diogo F. Ferreira, Adrià López-Baucells, Fabio Z. Farneda, Joao M.B. Carreiras, Jorge M. Palmeirim & Christoph F. J. Meyer
Understanding the consequences of habitat modification on wildlife communities is central to the development of conservation strategies. However, albeit male and female individuals of numerous species are known to exhibit differences in habitat use, sex-specific responses to habitat modification remain little explored. Here, we used a landscape-scale fragmentation experiment to assess, separately for males and females, the effects of fragmentation on the abundance of Carollia perspicillata and Rhinophylla pumilio, two widespread Neotropical frugivorous bats. We...

Data from: Zoonotic infection of Brazilian primate workers with New World simian foamy virus

Claudia P. Muniz, Liliane T. F. Cavalcante, Hongwei Jia, HaoQiang Zheng, Shaohua Tang, Anderson M. Augusto, Alcides Pissinatti, Luiz P. Fedullo, Andre F. Santos, Marcelo A. Soares & William M. Switzer
Simian foamy viruses (SFVs) are retroviruses present in nearly all nonhuman primates (NHPs), including Old World primates (OWP) and New World primates (NWP). While all confirmed human infections with SFV are from zoonotic transmissions originating from OWP, little is known about the zoonotic transmission potential of NWP SFV. We conducted a longitudinal, prospective study of 56 workers occupationally exposed to NWP in Brazil. Plasma from these workers was tested using Western blot (WB) assays containing...

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: Genetic dissection of adaptive form and function in rapidly-speciating cichlid fishes

Frederico Henning, Gonzalo Machado-Schiaffino, Lukas Baumgarten & Axel Meyer
Genes of major phenotypic effects and strong genetic correlations can facilitate adaptation, direct selective responses and potentially lead to phenotypic convergence. However, the preponderance of this type of genetic architecture in repeatedly-evolved adaptations remains unknown. Using hybrids between Haplochromis chilotes (thick-lipped) and H. nyererei (thin-lipped) we investigated the genetics underlying hypertrophied lips and elongated heads, traits that evolved repeatedly in cichlids. At least 25 loci of small-to-moderate and mainly additive effects were detected. Phenotypic variation...

Data from: Misuse of bird digital distribution maps creates reversed spatial diversity patterns in the Amazon

Mariana M. Vale, Tamires L. Marques, Mario Cohn-Haft & Marcus Vinícius Vieira.
It is well known that bird richness in the Amazon is greater in upland forests and that seasonally flooded forest is particularly species poor. However, the misleading pattern of greater bird richness in seasonally flooded forest has emerged seemingly unnoticed numerous times in richness maps in the literature. We hypothesize that commission errors in digital distribution maps (DDMs) are the cause behind the misleading richness pattern. In the Amazon, commission errors are a consequence of...
