Power Cascade Morphogenesis of Bird Beaks and the Generation of Exceptions

open access: yesEvolution &Development, Volume 28, Issue 4, December 2026.
Adult bird species with power cascade beaks (Australian zebra finch Taeniopygia castanotis; chicken Gallus gallus; and southern cassowary Casuarius casuarius) show a consistent linear pattern of growth. An exception is the Royal Spoonbill (Platalea regia) which has a primordial beak that follows and then grows to break the power cascade.

Lysine Requirements in Starter‐Phase Japanese Quail (Coturnix japonica) Through Dose–Response Modelling: Interactions With Dietary Protein Level

open access: yesVeterinary Medicine and Science, Volume 12, Issue 6, November 2026.
In starter Japanese quail, optimal lysine requirements (1.32%–1.42%) depend on dietary crude protein level. Supplementation at 1.4% maximizes body weight gain, protein efficiency, and breast yield, while oversupply (1.55%) impairs performance. Linear broken‐line modelling provides the most reliable requirement estimates for precision feeding.

Interactive Effects of Dietary Crude Protein and Methionine Levels on Growth Performance, Carcass Quality and Blood Biochemistry of Japanese Quail During Starter and Grower Phases

open access: yesVeterinary Medicine and Science, Volume 12, Issue 6, November 2026.
Dietary crude protein and methionine interact significantly in Japanese quail. Optimal methionine ranges from 0.50%–0.70% depending on protein level and phase. Best grower performance occurs at 25% CP with 1.30% Met, yielding 161.84 g male weight gain. Females show superior breast yield (30.90%).

Site‐specific curtailment thresholds substantially reduce bat mortality at wind energy facilities

open access: yesJournal of Applied Ecology, Volume 63, Issue 10, October 2026.
Our findings demonstrate that site‐specific operational thresholds, derived from acoustic data and meteorological conditions, substantially reduce bat mortality at wind energy facilities. As the largest standardized assessment of curtailment effectiveness and the first in Europe, this study supports the widespread adoption of site‐specific curtailment ...
