A meta‐analysis of the effect of visiting zoos and aquariums on visitors’ conservation knowledge, beliefs, and behavior

Conservation Biology, Volume 39, Issue 1, February 2025.
Abstract Zoos and aquariums are well placed to connect visitors with the issues facing biodiversity globally and many deliver interventions that seek to influence visitors’ beliefs and behaviors with respect to conservation. However, despite primary studies evaluating the effect of such interventions, the overall effect of engaging with zoos and the ...

Is it all about size? Dismantling the integrated phenotype to understand species coexistence and niche segregation

Functional Ecology, Volume 38, Issue 11, Page 2350-2368, November 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Niche segregation is a mechanism by which competition between coexisting species is reduced. The ecological niche is a multidimensional space shaped by the conditions and resources that enable the existence of species.

C‐reactive protein (CRP) in high altitude Bolivian peri‐urban adolescents varies by adiposity, current illness, height, socioeconomic status, sex, and menarcheal status: The potential benefits and costs of adipose reserves in arduous environments

American Journal of Human Biology, Volume 36, Issue 9, September 2024.
Abstract Objectives In non‐industrialized and low‐income populations, adipose stores can serve as a valuable buffer against harsh conditions such as seasonal food scarcity. However, these reserves may incur costs due to adipocytes' production of pro‐inflammatory cytokines; inflammation is associated with increased risk for cardiometabolic diseases ...

Ecology explains anhydrobiotic performance across tardigrades, but the shared evolutionary history matters more

Journal of Animal Ecology, Volume 93, Issue 3, Page 307-318, March 2024.
This study offers a novel approach to quantify desiccation (anhydrobiosis) tolerance. It shows that ancestral history (phylogeny), rather than current habitat (ecology), explains most of the considerable interspecific variation in this trait across tardigrades. Abstract Desiccation stress is lethal to most animals.
