Natal dispersal is a critical trait for individual fitness and the viability, structure, and genetic identity of populations. However, there is a pronounced information gap for large and long-lived species due to the difficulty of monitorin...
Antipredator decisions of male Trinidadian guppies (Poecilia reticulata) depend on social cues from females [0.03%]

Powered flight in birds is reliant on feathers forming an aerodynamic surface that resists air pressures. Many basic aspects of feather functionality are unknown, which hampers our understanding of wing function in birds. This study measure...

Acoustic communication signals are important for species recognition and mate attraction across numerous taxa. For instance, most of the thousands of species of frogs have a species-specific advertisement call that females use to localize a...

The increasing interest in the study of spontaneous (SY) and contagious yawning (CY) was so far focused on several taxa, especially primates. Here, we focused on SY and CY in horses, a suitable species due to their complex social dynamics t...
Claw coloration in the fiddler crab Leptuca uruguayensis has no correlation with male quality [0.03%]

Sexual selection is thought to play a major role in the evolution of color due to the correlation between a signaler's physiological state and the displayed color. As such, researchers often investigate how color correlates to the quality o...
Effects of captive-breeding conditions on metabolic and performance traits in an endangered, endemic cyprinidontiform fish [0.03%]

Captive breeding and stocking are commonly employed strategies for enhancing fisheries and conserving endangered fish species. However, hatchery-raised fish often exhibit reduced performance in the wild, displaying alterations in physiologi...
The pronotum shape of scelimenine grasshoppers (Orthoptera: Tetrigidae) likely represents an exaptation for heterogeneous niche colonization [0.03%]

Insects are suitable model organisms for functional morphology research, especially in the context of exaptation, when the same morphological trait represents an advantage in disparate niches. Phylogenetically distant groups of pygmy grassh...
