The Secret of Secrets: Carbonic Anhydrase Concentration in Lizards' Femoral Gland Secretions Is Tuned to Environmental Conditions Open
Among the modalities of animal communication, the chemical channel is the only one that allows signalers and receivers to communicate without being necessarily in the same place at the same time. This asynchrony may influence signal design…

Age-dependent self- and individual chemosensory discrimination in male Psammodromus algirus lizards is based on lipids and proteins from their scent Open
Self- and individual discrimination are needed to maintain social relationships. However the extent of precision of these abilities may depend on the social strategy of each individual, which may vary with ontogeny. Many animals use chemic…

Host species and age‐specific variation on <i>Hepatozoon</i> prevalence and its effect on body condition in two Neotropical crocodiles Open
Many populations of species belonging to the order Crocodilia are threatened due to illegal trafficking, indiscriminate hunting, and habitat loss and degradation affecting crocodilian health and parasitic load. Although several studies hav…

Do sexual differences in life strategies make male lizards more susceptible to parasite infection? Open
Female and male hosts may maximise their fitness by evolving different strategies to compensate for the costs of parasite infections. The resulting sexual dimorphism might be apparent in differential relationships between parasite load and…

Heat-altered scent marks of males of a fossorial reptile still allow recognition by females but lose information on male quality Open
The efficacy of sexual signals in communication is often maximized under specific environmental conditions. Anthropic alterations of these conditions might, thus, negatively affect communication during reproductive behavior. In fossorial a…

A global analysis of field body temperatures of active squamates in relation to climate and behaviour Open
Aim Squamate fitness is affected by body temperature, which in turn is influenced by environmental temperatures and, in many species, by exposure to solar radiation. The biophysical drivers of body temperature have been widely studied, but…

Blind date: female fossorial amphisbaenians prefer scent marks of large and healthy males Open
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 individual. In fossorial animals, inhabiting visually restrict…

Coping with drought? The hidden microhabitat selection and underground movements of amphisbaenians under summer drought conditions Open
Habitat selection is a dynamic process that depends on many environmental variables that can vary with weather conditions. This is important because, within a context of global change, extreme weather events, such as severe droughts, are p…

Multiple Chemical Signals in Male Rock Lizards: Femoral Gland Secretions and Feces May Provide Information on Body Size but Using Different Compounds Open
Chemosensory communication in lizards may be based on multiple compounds coming from multiple sources. Both secretions from external epidermal glands, and internal cloacal glands and feces are known to convey information (sex, familiarity,…
