Predicting risk to bat species from wind turbine collision in Southeast Asia.

Wind farms can pose significant risks to bat populations through collisions with turbines, habitat loss, and effects on behavior. With its rich bat diversity and expanding wind power industry, Southeast Asia lacks sufficient data to assess the risks posed to bat species from wind turbine collisions. We aimed to develop a predictive framework for assessing wind turbine risk to bats in Southeast Asia based on global bat fatality data and trait-based assessments.

How do King Cobras move across a major highway? Unintentional wildlife crossing structures may facilitate movement.

Global road networks continue to expand, and the wildlife responses to these landscape-level changes need to be understood to advise long-term management decisions. Roads have high mortality risk to snakes because snakes typically move slowly and can be intentionally targeted by drivers.We investigated how radio-tracked King Cobras () traverse a major highway in northeast Thailand, and if reproductive cycles were associated with road hazards.

Reptiles on the wrong track? Moving beyond traditional estimators with dynamic Brownian Bridge Movement Models.

Background: Animal movement expressed through home ranges or space-use can offer insights into spatial and habitat requirements. However, different classes of estimation methods are currently instinctively applied to answer home range, space-use or movement-based research questions regardless of their widely varying outputs, directly impacting conclusions. Recent technological advances in animal tracking (GPS and satellite tags), have enabled new methods to quantify animal space-use and movement pathways, but so far have primarily targeted mammal and avian species.

No room to roam: King Cobras reduce movement in agriculture.

Background: Studying animal movement provides insights into how animals react to land-use changes. As agriculture expands, we can use animal movement to examine how animals change their behaviour in response. Recent reviews show a tendency for mammalian species to reduce movements in response to increased human landscape modification, but reptile movements have not been as extensively studied.

Electrophysiological Measures of Aging Pharynx Function in C. elegans Reveal Enhanced Organ Functionality in Older, Long-lived Mutants.

The function of the pharynx, an organ in the model system Caenorhabditis elegans, has been correlated with life span and motility (another measure of health) since 1980. In this study, in order to further understand the relationship between organ function and life span, we measured the age-related decline of the pharynx using an electrophysiological approach. We measured and analyzed electropharyngeograms (EPG) of wild type animals, short-lived hsf-1 mutants, and long-lived animals with genetically decreased insulin signaling or increased heat shock pathway signaling; we recorded a total of 2,478 EPGs from 1,374 individuals.
