We provide a first test whether female colour variation in common blue butterflies (a) has arisen through cross‐sexual transfer. Analyses of museum specimens (b) show that the distribution of females wing colour varies in a geographic mosaic pattern, and laboratory experiments (c) show that this variation is both genetically determined and impacted by ...

The sensory drive hypothesis predicts that the coevolution of signaling traits and sensory perception may contribute to reproductive isolation and speciation. We tested whether opsin protein expression differs between divergent lineages of the tawny dragon (Ctenophorus decresii) that differ in the presence/absence of an ultraviolet sexual signal.

Generation length of the world's amphibians and reptiles
Variation in life histories influences demographic processes, from adaptive changes to population declines leading to extinction. Among life history traits, generation length offers a critical feature to forecast species' demographic trajectories such as population declines (widely used by the IUCN Red List) and adaptability to environmental change ...

Using both conventional and phylogenetic comparative methods we found a significant negative correlation between targets for pre‐ and postcopulatory selection in squamate reptiles. This evolutionary pattern suggests that strong precopulatory selection may often constrain the opportunity for postcopulatory selection, and that the relative importance of ...

Filling gaps in the geographic distribution of Anolis fuscoauratus d’Orbigny, 1837 (Squamata, Dactyloidae) in the southeastern Brazilian Atlantic Forest [PDF]
We update the southeastern distribution of Anolis fuscoauratus d’Orbigny, 1837 based on newly collected specimens and on specimens from scientific collections misidentified or deposited with questionable identifications. We include&

We found that recurrent positive selection has acted on TLR2 and MyD88 in amphibians and positively selected sites were mainly located at or close to function domains. Our results suggest that amphibians have adapted to different pathogenic microorganisms during their transition from the aquatic to terrestrial environment and diversification into ...

ABSTRACT Turbinals are bony or cartilaginous structures that are present in the nasal cavity of most tetrapods. They are involved in key functions such as olfaction, heat, and moisture conservation, as well as protection of the respiratory tract. Despite recent studies that challenged long‐standing hypotheses about their physiological and genomic ...

Relación entre el tipo de percha y el comportamiento de agresividad en el lagarto Norops polylepis (Squamata: Dactyloidae) [PDF]
The intensity of aggression against intruders by owners of a territory has been related to the type of resources available to an individual within its territory.

Sex determination systems have greatly diversified between amphibians and reptiles. In this review, we discuss the diversity of sex chromosomes in amphibians and reptiles resulted from comparative analyses of chromosome homology of sex chromosomes in amphibians and reptiles reported so far, using the genome of the chicken, which is thought to resemble ...

Although most prey are attacked by multiple predators, much of the ecological theory on prey suppression focuses on the effects of a single predator. The presence of multiple predators can lead to complex interactions such as trait-mediated interactions (
