Matching Multiple Backgrounds: Egg Camouflage Across Different Habitats in a Shorebird

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
We studied egg camouflage in Kentish plovers nesting in two visually distinct habitats, sandy beaches and salt marshes, in southern Spain. Despite initial expectations of local adaptation or compromise camouflage, the birds instead chose nest sites within each habitat that shared overlapping colour and visual texture characteristics, allowing effective

Postcopulatory sexual selection favors fertilization success of restocking hybrid quails over native Common quails (Coturnix coturnix) [PDF]

open access: yes, 2015
Postcopulatory sexual selection plays an important role in the reproductive success of males in many species. Differences in fertilization success could affect rates of admixture and genetic introgression between divergent lineages. We investigated sperm

Ultrasound‐Activated Biodegradable Piezoelectric Chitosan Nanoparticles for Glioblastoma Treatment

open access: yesSmall Science, Volume 6, Issue 1, January 2026.
Biodegradable chitosan nanoparticles are engineered to exhibit intrinsic piezoelectric properties, enabling ultrasound (US) activation for glioblastoma treatment. Their electromechanical behavior, biocompatibility, and anticancer efficacy are demonstrated, showing that US‐driven piezostimulation induces oxidative stress and apoptosis without drugs ...

Using step width to compare locomotor biomechanics between extinct, non-avian theropod dinosaurs and modern obligate bipeds [PDF]

open access: yes, 2017
How extinct, non-avian theropod dinosaurs locomoted is a subject of considerable interest, as is the manner in which it evolved on the line leading to birds. Fossil footprints provide the most direct evidence for answering these questions. In this study,

Safety Assessment of Repeated Oral Administration of Tolfenamic Acid in Japanese Quails: Haematological, Biochemical and Histopathological Evaluations

open access: yesVeterinary Medicine and Science, Volume 12, Issue 1, January 2026.
Safety of tolfenamic acid in Japanese quails. ABSTRACT Objective This study evaluated the safety profile of tolfenamic acid following repeated oral administration in Japanese quails (Coturnix coturnix japonica) at doses of 2 and 8 mg/kg every 12 h for 7 days. Methods The 42 quails were randomly assigned to three groups. The first group (n = 6) received

The hearing capabilities of the Dromornithidae (Aves), with inferences on acoustic communication and ecology

open access: yesJournal of Anatomy, Volume 248, Issue 1, Page 82-93, January 2026.
The preservation of bony structures which enclose the hearing organs (ECD) provide a basis for interpreting the hearing capabilities of the extinct, flightless Dromornithidae (Aves). Although the length of the dromornithid ECD was especially short, relative to basicranial length, it conformed to the negative allometric scaling relationships observed in
