Color polymorphism defies evolutionary expectations as striking phenotypic variation is
maintained within a single species. Color and other traits mediate social interactions, and …

The uropygial gland of birds produces an oily secretion with different functions, mainly
related to plumage protection. In addition, the volatile compounds of this secretion may act …

Studies of animal communication have documented myriad rapid, context‐dependent
changes in visual and acoustic signal design. In contrast, relatively little is known about the …

Conspecific cues often provide social information on habitat quality that is considered when
deciding to settle at a specific site. The type of sensory cues useful for this will depend on the …

During the mating season, Iberian red deer males (Cervus elaphus hispanicus) present a
large visible dark ventral area in their abdomen. This characteristic dark-haired area is …

The efficacy of sexual signals in communication is often maximized under specific
environmental conditions. Anthropic alterations of these conditions might, thus, negatively …

Parasites impact host fitness and constitute an important selective pressure on the host's life
history. According to parasite‐mediated sexual selection, ornaments are presumed to …

Selecting a good mate is a decision with important fitness consequences. For this reason,
mate choice has promoted the evolution of sexual ornaments signaling the quality of an …

Background Many animals rely on chemical cues for intraspecific communication. This is
especially important in fossorial animals because visual restrictions of the underground …

Chemosensory communication in lizards may be based on multiple compounds coming
from multiple sources. Both secretions from external epidermal glands, and internal cloacal …
