A new species of jewel‐babbler (Cinclosomatidae: Ptilorrhoa) from the Southern Fold Mountains of Papua New Guinea

Ibis, Volume 168, Issue 2, Page 431-450, April 2026.
Based on distinctive morphological and vocal characters we describe a new species of jewel‐babbler (genus Ptilorrhoa) from the forested karst of the Southern Fold Mountains in Papua New Guinea. The description is based on camera trap data and is presented in accordance with ICZN Declaration 45.

Comparative Neuromechanical Wing‐Actuation Architectures of Flapping Flight in Insects, Hummingbirds, and Robots

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.
Natural fliers achieve remarkable aerial performance through diverse wing neuromechanical systems integrating actuation, sensing, and control. This study synthesizes neuromechanical architectures in insects and hummingbirds, identifying two key functional types‐Dual Neural‐Mechanical Oscillator and Neurally‐modulated Mechanical Oscillator‐ and ...

Theoretical study of stimulated and spontaneous Hawking effects from an acoustic black hole in a hydrodynamically flowing fluid of light

, 2016
We propose an experiment to detect and characterize the analog Hawking radiation in an analog model of gravity consisting of a flowing exciton-polariton condensate.

Swimming modes affect dive durations in diving birds

Journal of Avian Biology, Volume 2026, Issue 2, March 2026.
Dive duration and body mass are positively correlated across air‐breathing vertebrate species, but other factors affecting dive duration are inadequately studied. Here, we examined the effect of a previously overlooked factor, swimming mode, using phylogenetically informed statistics with data on the diving capabilities of 53 species of avian divers ...

The Na+/Ca2+, K+ exchanger NCKX4 is required for efficient cone-mediated vision [PDF]

, 2017
Calcium (Ca2+) plays an important role in the function and health of neurons. In vertebrate cone photoreceptors, Ca2+ controls photoresponse sensitivity, kinetics, and light adaptation.

Behavioural responses of a gamebird to human encounters across the hunting season

Wildlife Biology, Volume 2026, Issue 2, March 2026.
We examined the behavioural adaptation of rock ptarmigan Lagopus muta in response to human encounters across the hunting season. We conducted disturbance experiments in two different parts of the species' range, in subarctic (Iceland) and in alpine (Italy) habitats.

Avian influenza overview December 2025–February 2026

EFSA Journal, Volume 24, Issue 3, March 2026.
Abstract Between 29 November 2025 and 27 February 2026, 2514 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (406) and wild (2108) birds in 32 countries in Europe. Albeit still at high levels after the peak was reached at the beginning of the current reporting period, the weekly number of detections has since ...

The Genetic and Morphological Basis of Local Adaptation to Elevational Extremes in an Alpine Finch

Ecology and Evolution, Volume 16, Issue 2, February 2026.
We investigated morphological and genetic variation in the Sierra Nevada Gray‐crowned Rosy Finch to identify traits important for local adaptation in alpine environments. By combining trait measurements with genome‐wide analyses, we uncovered loci linked to thermoregulation, altitude adaptation, and cold tolerance.
