Data from: Characteristics of patients with smear-negative pulmonary tuberculosis (TB) in a region with high TB and HIV prevalence

Leandro C. Campos, Marcus V. V. Rocha, Denise Maria Cunha Willers, Denise Rossato Silva & Marcos Vinícius Vieira Rocha
Introduction: Smear-negative pulmonary TB (SNPT) represents 30–60% of all pulmonary TB cases. The mortality of these patients can reach 25% in populations with high prevalence of HIV infection, and 10–20% of TB transmission at the population level are attributable to SNPT cases. Methods: We conducted a retrospective study to evaluate epidemiological, clinical, and radiological characteristics of patients with SNPT and to compare these with patients who were diagnosed as having smear-positive pulmonary TB (SPPT). All...

Data from: The ecology of a continental evolutionary radiation: Is the radiation of sigmodontine rodents adaptive?

Renan Maestri, Leandro Rabello Monteiro, Rodrigo Fornel, Nathan S. Upham, Bruce D. Patterson & Thales Renato Ochotorena De Freitas
Evolutionary radiations on continents are less well-understood and appreciated than those occurring on islands. The extent of ecological influence on species divergence can be evaluated to determine whether a radiation was ultimately the outcome of divergent natural selection or else arose mainly by nonecological divergence. Here, we used phylogenetic comparative methods to test distinct hypotheses corresponding to adaptive and nonadaptive evolutionary scenarios for the morphological evolution of sigmodontine rodents. Results showed that ecological variables (diet...

Data from: Population differentiation in the context of Holocene climate change for a migratory marine species, the southern elephant seal

Laura J. Corrigan, Anna Fabiani, Lucas F. Chauke, Clive R. McMahon, Mark De Bruyn, Marthan N. Bester, Amanda Bastos, Claudio Campagna, Monica M.C. Muelbert & A. Rus Hoelzel
Understanding observed patterns of connectivity requires an understanding of the evolutionary processes that determine genetic structure among populations, with the most common models being associated with isolation by distance, allopatry or vicariance. Pinnipeds are annual breeders with the capacity for extensive range overlap during seasonal migrations, establishing the potential for the evolution of isolation by distance. Here we assess the pattern of differentiation among six breeding colonies of the southern elephant seal, Mirounga leonina, based...

Data from: Shifts and linkages of functional diversity between above- and below-ground compartments along a flooding gradient

Corentin Abgrall, Matthieu Chauvat, Estelle Langlois, Mickaël Hedde, David Mouillot, Sandrine Salmon, Bruna Winck & Estelle Forey
Trait-based approaches have the potential to reveal general and predictive relationships between organisms and ecosystem functioning. However, the mechanisms underlying the functional structure of communities are still unclear. Within terrestrial ecosystems, several studies have shown that many ecological processes are controlled by the interacting above- and below-ground compartments. However, few studies have used traits to reveal the functional relationships between plants and soil fauna. Mostly, research combining plants and soil fauna solely used the traits...
