Digital surveillance of animals and nature recovery

People and Nature, EarlyView.
Abstract Digital surveillance technologies (DSTs) are widely applied in nature recovery for their potential to generate novel data on species and ecosystems through digital tracking, automation (e.g. from hazardous locations) and from newly recruited citizen scientists.

Programmed unmanned aerial vehicles show great potential for monitoring marine megafauna in specific areas of interest

Remote Sensing in Ecology and Conservation, EarlyView.
Targeted conservation measures are contingent on robust knowledge of spatio‐temporal animal distribution in areas of interest. We explore unmanned aerial vehicle (UAV) transect monitoring as a novel method for standardized digital aerial surveys of marine megafauna by investigating the fine‐resolution spatio‐temporal distribution of harbour porpoises ...

Inter‐Crystal Spacing of Implantable Polymeric Surfaces as a Key Suppressor of Microbial Adhesion.

Small, EarlyView.
Biofilm formation on implantable devices is addressed by controlling inter‐crystal spacing in shape memory polymers. Repeated shape recovery aligns and enlarges crystalline phases and reduces amorphous regions, enhancing bacterial repellency. Three biofilm‐forming bacteria show reduced adhesion, and a one‐year dog bile‐duct model maintains function ...

Undergraduate Women Socially Develop Science Identities Through Everyday Talk and Recognition: A Mixed Methods Study

Journal of Research in Science Teaching, EarlyView.
ABSTRACT Science identity is a key predictor of persistence in STEM. Although prior research has established the importance of social recognition for identity development, less is known about how recognition operates within informal, everyday interactions.

Trace Element Contamination in Top Predatory Elasmobranchs From the Southern Black Sea: Implications for Ecosystem Health and Risk Assessment

Environmental Toxicology, EarlyView.
ABSTRACT Environmental pollution resulting from the rapid increase in human population, urbanization, intensive use of chemicals in agriculture, and industrial development has reached a level that threatens natural life today. Trace elements are one of the most important factors causing significant levels of pollution in the environment and are added ...
