Cross-sectional study of personal protective equipment use, training and biosafety preparedness among healthcare workers during the first months of the SARS-CoV-2 pandemic in Brazil.

Objectives: Brazil has high rates of COVID-19 and tuberculosis among healthcare workers (HCWs). Personal protective equipment (PPE) is essential for their protection. We aimed to evaluate PPE use, training, and preparedness among HCWs in the early months of the SARS-CoV-2 pandemic in Brazil.

Geographic Transitions of Domestic Cats in Urban Areas through Animal Adoption Centers and the Implications for Population Dynamics.

Animal shelters address animal welfare in communities through the intake and outcome of companion animals, but these efforts affect population dynamics of companion animals based on the distance animals are moved and the factors that underlie intake and outcome. Using data from an animal shelter in Washington, DC we analyzed cat intakes and outcomes based on geographic and socioeconomic factors. Most intakes were stray cats (59%) and cats relinquished by owners (38%) and most outcomes were adoptions (84%).

Anticipated effects of abiotic environmental change on intraspecific social interactions.

Social interactions are ubiquitous across the animal kingdom. A variety of ecological and evolutionary processes are dependent on social interactions, such as movement, disease spread, information transmission, and density-dependent reproduction and survival. Social interactions, like any behaviour, are context dependent, varying with environmental conditions.

Experimental evidence that density mediates negative frequency-dependent selection on aggression.

Aggression can be beneficial in competitive environments if aggressive individuals are more likely to access resources than non-aggressive individuals. However, variation in aggressive behaviour persists within populations, suggesting that high levels of aggression might not always be favoured. The goal of this study was to experimentally assess the effects of population density and phenotypic frequency on selection on aggression in a competitive environment.

Need for multiscale planning for conservation of urban bats.

For over a century there have been continual efforts to incorporate nature into urban planning. These efforts (i.e.
