Begging behavior as an honest signal of need and parent–offspring association during the postfledging dependency period

Ecology and Evolution, 2019
Honest signaling mechanisms can function to appropriate care to hungry offspring and avoid misdirected care of unrelated offspring. Begging, the behavior by which offspring solicit food and parental care, may be an honest signaling mechanism for need, as

Efficacy of CagriSema for Reaching Anthropometric Treatment Targets and Cardiometabolic Outcomes: A Secondary, Post hoc Analysis of REDEFINE 1

Diabetes, Obesity and Metabolism, Volume 28, Issue 10, Page 9317-9325, October 2026.
ABSTRACT Aims To assess the added value of absolute anthropometric targets alongside percentage weight loss in the clinical management of obesity. Materials and Methods The phase 3a, 68‐week REDEFINE 1 trial randomised adults without diabetes with BMI ≥ 30 kg/m2, or ≥ 27 kg/m2 with ≥ 1 obesity‐related complication, to once‐weekly CagriSema 2.4 mg/2.4 ...

Testing for assortative mating based on migratory phenotypes in the Common Tern (Sterna hirundo)

Avian Research
Tracking and mating data of Common Terns (Sterna hirundo) breeding in a single colony in north-eastern Germany were used to test for assortative mating in regards to migratory phenotypes.

A First Indication That Rainforest Vine Proliferation Does Not Enhance Predator–Prey Interactions on the Forest Floor

Entomologia Experimentalis et Applicata, Volume 174, Issue 10, Page 1229-1241, October 2026.
Vine proliferation is a widespread consequence of tropical forest disturbance, yet its effects on ground‐level predator–prey interactions remain poorly understood. Using plasticine caterpillars deployed on the rainforest floor in north Queensland, Australia, we show that overall predation rates were unaffected by vine‐to‐tree ratio. Instead, fine‐scale

Threatened cockatoo adapts foraging strategy to survive habitat loss from fire

Ibis, Volume 168, Issue 4, Page 1664-1680, October 2026.
Fire regimes are changing across the globe as a result of human‐induced climate change. For granivorous bird species, changes in fire regimes can affect seed availability and the persistence of populations. We investigated the foraging behaviour of Glossy Black Cockatoos Calyptorhynchus lathami halmaturinus, a resource specialist, following large‐scale

Connectivity between breeding sites, wintering areas, and migration routes in Common Terns (Sterna hirundo) breeding in the Western Palaearctic

Ibis, Volume 168, Issue 4, Page 1230-1240, October 2026.
Detailed knowledge about bird migration patterns can enhance our understanding of the evolution of migration and temporal changes in space use throughout the annual cycle. Additionally, as many migratory bird species are experiencing population declines, understanding the connectivity between their spatial distributions during breeding, migration and ...
