Acoustic and Genetic Data Can Reduce Uncertainty Regarding Populations of Migratory Tree-Roosting Bats Impacted by Wind Energy.

Wind turbine-related mortality may pose a population-level threat for migratory tree-roosting bats, such as the hoary bat () in North America. These species are dispersed within their range, making it impractical to estimate census populations size using traditional survey methods. Nonetheless, understanding population size and trends is essential for evaluating and mitigating risk from wind turbine mortality.

Influencing Activity of Bats by Dimly Lighting Wind Turbine Surfaces with Ultraviolet Light.

Wind energy producers need deployable devices for wind turbines that prevent bat fatalities. Based on the speculation that bats approach turbines after visually mistaking them for trees, we tested a potential light-based deterrence method. It is likely that the affected bats see ultraviolet (UV) light at low intensities.

An investigation into the potential for wind turbines to cause barotrauma in bats.

The high rates of bat mortality caused by operating wind turbines is a concern for wind energy and wildlife stakeholders. One theory that explains the mortality is that bats are not only killed by impact trauma, but also by barotrauma that results from exposure to the pressure variations caused by rotating turbine blades. To date, no published research has calculated the pressure changes that bats may be exposed to when flying near wind turbines and then used these data to estimate the likelihood that turbines cause barotrauma in bats.

Social Network Analysis of a Simulation Community.

Introduction: Graphical analysis of networking maps can be used to measure the health, connectivity, and vulnerabilities of a professional community. We aimed to capture and map the connections and relationships between individuals and organizations in the healthcare simulation community of the state of Western Australia. It was also intended that this analysis would encourage new opportunities for collaboration to advance simulation-based education.

[Terminology for classifying the porcine reproductive and respiratory syndrome virus (PRRSV) status of swine herds].

Standardized terminology for the porcine reproductive and respiratory syndrome virus (PRRSV) status of swine herds is necessary to facilitate communication between veterinarians, swine producers, genetic companies, and other industry participants. It is also required for implementation of regional and national efforts towards PRRSV control and elimination. The purpose of this paper is to provide a herd classification system for describing the PRRSV status of herds, based upon a set of definitions reflecting the biology and ecology of PRRSV.
