The trans-european catchment area of common noctule bats killed by wind turbines in France.

Wind turbines used to combat climate change pose a green-green dilemma when endangered and protected wildlife species are killed by collisions with rotating blades. Here, we investigated the geographic origin of bats killed by wind turbines along an east-west transect in France to determine the spatial extent of this conflict in Western Europe. We analysed stable hydrogen isotopes in the fur keratin of 60 common noctule bats (Nyctalus noctula) killed by wind turbines during summer migration in four regions of France to predict their geographic origin using models based on precipitation isoscapes.

Peer E-Cigarette and Cannabis Use and Adolescent Anxiety: Findings from a Mixed-Methods Study.

Objective: Adolescents are typically motivated to conform to peer influence, including substance use behaviors, and it is likely that adolescents who deviate from their peers' substance use behaviors might experience stress and anxiety.

Method: A mixed-methods approach was utilized to examine the relationship between peer e-cigarette and cannabis use and symptoms of generalized anxiety among a diverse sample of 12 grade students in Los Angeles County, California, USA ( = 1,867, = 17.04, SD = 0.

Change in depression and anxiety symptoms among university students, staff, and faculty during the COVID-19 pandemic: Trojan pandemic response initiative.

Objective, Participants, & Methods: The COVID-19 pandemic has exacerbated mental health challenges of university students, staff, and faculty alike. We used linear mixed models to examine demographic predictors of, and change over time in, self-reported depression and anxiety symptoms of a cohort of university students and staff/faculty between surveys administered in August-November 2021 and December 2021-March 2022.

Results: Students who identified as "other" race/ethnicity, Lesbian Gay Bisexual or Queer, and female, reported high baseline levels of both depression and anxiety.

Bacterial communities on giant kelp in the Magellan Strait: Geographical and intra-thallus patterns.

The giant kelp Macrocystis pyrifera is categorized as a keystone species, forming highly productive forests that provide ecosystem services and host a remarkable marine biodiversity of macro and microorganisms. The association of microorganisms with the algae is close and can be functionally interdependent. The Magellan Strait, a natural marine passage between the Atlantic and Pacific oceans, harbours extensive giant kelp forests.
