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

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: Age, gender, neck circumference, and Epworth sleepiness scale do not predict obstructive sleep apnea (OSA) in moderate to severe chronic obstructive pulmonary disease (COPD): the challenge to predict OSA in advanced COPDXavier Soler, S.Y. Liao, J.M. Marin, G. Lorenzi-Filho, R. Jen, P. DeYoung, R.L. Owens, A.L. Ries & A. Malhotra
The combination of chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) is associated with substantial morbidity and mortality. We hypothesized that predictors of OSA among patients with COPD may be distinct from OSA in the general population. Therefore, we investigated associations between traditional OSA risk factors (e.g. age), and sleep questionnaires [e.g. Epworth Sleepiness Scale] in 44 patients with advanced COPD. As a second aim we proposed a pilot, simplified screening test for...
The estimation of diversification rates is one of the most vividly debated topics in modern systematics, with considerable controversy surrounding the power of phylogenetic and fossil-based approaches in estimating extinction. Van Valen’s seminal work from 1973 proposed the “Law of constant extinction” which states that the probability of extinction of taxa is not dependent on their age. This assumption of age-independent extinction has prevailed for decades with its assessment based on survivorship curves, which, however,...
Data from: Inferring the geographic origin of a range expansion: latitudinal and longitudinal coordinates inferred from genomic data in an ABC framework with the program X-ORIGINQixin He, Joyce R. Prado & Laura Lacey Knowles
Climatic or environmental change is not only driving distributional shifts in species today, but it has also caused distributions to expand and contract in the past. Inferences about the geographic locations of past populations, especially regions that served as refugia (i.e., source populations) and migratory routes are a challenging endeavor. Refugial areas may be evidenced from fossil records or regions of temporal stability inferred from ecological niche models. Genomic data offer an alternative and broadly...

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: The curious case of Bradypus variegatus sloths: populations in threatened habitats are biodiversity components needing protectionSofia Marques Silva, José A. Dávila, Bryson Voirin, Susana Lopes, Nuno Ferrand & Nadia Moraes-Barros
Studying Neotropical wild populations is of particular interest. While this region is facing an escalating habitat degradation, it also has remarkable biodiversity levels, whose origin we are only beginning to understand. A myriad of processes might have had idiosyncratic effects on its numerous species. Within the hottest Neotropical biodiversity hotspot, the Atlantic Forest (AF), species and genetic diversities are organized latitudinally, with decreasing diversity levels southwards. Bradypus variegatus, the brown-throated three-toed sloth, was one of...
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....
Data from: The evolution of phenotypic integration: how directional selection reshapes covariation in miceAnna Penna, Diogo Melo, Sandra Bernardi, Maria Ines Oyarzabal & Gabriel Marroig
Variation is the basis for evolution, and understanding how variation can evolve is a central question in biology. In complex phenotypes, covariation plays an even more important role, as genetic associations between traits can bias and alter evolutionary change. Covariation can be shaped by complex interactions between loci, and this genetic architecture can also change during evolution. In this article, we analyzed mouse lines experimentally selected for changes in size to address the question of...
Data from: Influence of historical land use and modern agricultural expansion on the spatial and ecological divergence of sugarcane borer, Diatraea saccharalis (Lepidoptera: Crambidae) in BrazilVitor A.C. Pavinato, Andrew P. Michel, Jaqueline B. De Campos, Celso Omoto & Maria I. Zucchi
Human-mediated changes in landscapes can facilitate niche expansion and accelerate the adaptation of insect species. The interaction between the evolutionary history of the sugarcane borer, Diatraea saccharalis Fabricius, and historical and modern agricultural activity in Brazil shaped its spatial genetic structure, facilitating ecological divergence and incipient host-shifting. Based on microsatellite data, STRUCTURE analyses identified two (K=2) and three (K=3) significant genetic clusters that corresponded to: a) a strong signal of spatial genetic structure and, b)...
Reduction of CO2 emissions will require a transition from fossil fuels to alternative energy sources. Expansion of Brazilian sugarcane ethanol1, 2 provides one near-term scalable solution to reduce CO2 emissions from the global transport sector. In contrast to corn ethanol, the Brazilian sugarcane ethanol system may offset 86% of CO2 emissions compared to oil use, and emissions resulting from land-use change to sugarcane are paid back in just 2–8 years3, 4. But, it has been...
