Fishmeal Substitution With Feather Meal in the Diet of African Catfish (Clarias gariepinus): Effects on Growth Performance, Survival, and Feed Floatability

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Fish production represents an important sector, and limited access to feed is a major challenge faced by fish farmers. A potential solution is for farmers to produce their own feeds using cheaper and locally available ingredients. In order to identify alternative substitutes for conventional protein sources used in fish feed, this study was ...

A model to quantify the probability of collision between birds and aircraft: Applications for onboard lighting

open access: yesEcological Applications, Volume 36, Issue 3, April 2026.
Abstract Globally, bird and aircraft collisions are a major safety hazard and monetary expense for the aviation industry. Empirical evidence suggests that the behavioral response of an animal within close proximity of an approaching vehicle is a critical factor in determining whether a collision occurs.

ENHYDROSS: A New Mechanistic Model Supports the Trans‐Oceanic Dispersal Capability of Terrestrial Vertebrates

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We introduce ENHYDROSS, a new mechanistic model that uses optimal swimming speed and minimum cost of transport to estimate maximum dispersal distances and durations for vertebrates, enabling assessment of long‐distance oceanic dispersal potential. Applied to a range of extant and extinct animals, the model's estimates generally align with observed data;

Individual Escape Flight Performance Is Repeatable and Differs Between Long‐Tailed Finch (Poephila acuticauda) Subspecies but Not as Predicted by Asymmetrical Introgression

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We repeatedly tested 158 individual long‐tailed finches, Poephila acuticauda, of two different sub‐species and their hybrids for differences in their flight performances. Several flight performance variables were repeatable across individuals. Contrary to expectations, P. a. hecki individuals did not display superior flight performance to P.
