Early‐life environment drives long‐term decrease in adult body mass in a wild bird population

Journal of Animal Ecology, EarlyView.
Using more than 90,000 body mass measures of adult and nestling great tits Parus major, we show that the 1 SD decline in adult mass between 1978 and 2024 is a consequence of changes in the environment (i.e. increase in population density) experienced at early life.

“Why can't they put us to sleep if we are suffering?”: La Nada and the desire for euthanasia among institutionalized older adults in Peru

Medical Anthropology Quarterly, EarlyView.
Abstract In this article, I examine how institutionalized older adults in Peru articulate suffering through the idiom of la nada—“nothingness”—and how this shapes desires for euthanasia. Moving from close ethnography of bodies in space and time to structural and ethical discourses on euthanasia, I argue that calls for euthanasia arise not only from ...

Maximum Gape in Developing Macaca mulatta

American Journal of Biological Anthropology, Volume 191, Issue 3, November 2026.
ABSTRACT Objectives Maximum gape and bite force are two key metrics of primate craniodental performance, but without mitigating adaptations, large gapes are associated with reduced bite force. Primate craniodental morphology undergoes functional transitions across development, but how these performance variables vary with life‐history transitions is ...

First, He Was Adam, and Then, She Was Eve

Sexuality, Gender &Policy, Volume 9, Issue 4, November 2026.
ABSTRACT Trans* is an umbrella term that is used to describe people who identify with a gender that is different from their assigned sex at birth. There has been a marked increase in young people presenting to child and adolescent mental health services due to a lack of specialist gender clinics in the United Kingdom.

Heterosis in crosses between remnant populations of the rare prairie forb Silene regia: Implications for restoration genetics

American Journal of Botany, Volume 113, Issue 10, October 2026.
Abstract Premise Calls to adopt seed‐sourcing strategies in biological restoration that preserve local adaptation while maximizing genetic variation (e.g., regional admixture provenancing) are increasingly common. Heterosis, the increased fitness of progeny from crosses between populations relative to progeny from crosses within populations, could ...

Mosquito population dynamics are shaped by interactions among larval density, temperature, and relative humidity

Ecology, Volume 107, Issue 10, October 2026.
Abstract Understanding how variation in key abiotic and biotic factors interact at ecologically relevant spatial scales is crucial for predicting population dynamics, distributions, and abundances. This is especially true for vectors that transmit human pathogens.

Oro‐Facial Contact Behaviors in Wild White Bald‐Headed Uakaris (Cacajao calvus): First Documentation of Direct Facial Contact and Facial Investigation in Pitheciidae

Biotropica, Volume 58, Issue 5, September 2026.
We document the first instances of direct oro‐facial contact and facial investigation in wild Cacajao calvus. These rare observations expand the social repertoire of Pitheciidae, suggesting that close‐range tactile communication complements the visual signaling of their distinctive red faces.

Climatic niche position predicts population dynamics in Mediterranean shrubs after drought

Journal of Ecology, Volume 114, Issue 8, August 2026.
Climatic conditions closer to the species' climatic niche centroid generally resulted in higher population growth in two Mediterranean shrubs, but demographic responses differed between species and were further influenced by drought‐induced vegetation die‐off.

Overlap of nonbreeding wandering albatrosses with fisheries and implications for colony‐specific population trajectories at South Georgia

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.

Loving, Luchando, and Literacy: Bilingual Latinx Mothers and the Power of Testimonios in a Community Book Club

The Reading Teacher, Volume 80, Issue 1, July/August 2026.
This study centers bilingual Latinx mothers who engaged in cuentos and testimonios alongside their children during a community book club. Their stories, rooted in love, language, and resistance, challenge deficit narratives and redefine literacy as relational, multimodal, and culturally grounded—positioning mothers as powerful pedagogues and cultural ...
