SOLEDAD VALDECANTOS is an academic who published a paper in 2014 entitled Comparative morphology of Liolaemus lizards precloacal glands. SOLEDAD VALDECANTOS published this work as part of a team: Valdecantos, Soledad. Here is a description of this work: Liolaemid lizards and amphisbaenids have precloacal pores in the anterior border of the cloaca, where epidermal glands drain and expel pheromonal secretions. Precloacal glands occur usually only in males, but in those few species where both sexes have precloacal glands, these are larger in males. Only the morphology and/or histology of precloacal glands of amphisbaenids have been described, and it is unknown whether in lizards these glands differ across ages, sexes and/or species, and if the lack of pores is associated with a lack of glands. We investigated for the first time the morphology and histology of lizard precloacal glands, by studying three Liolaemus species that differ in the presence of pores in their cloaca: L. irregularis, in which adults and juveniles of both sexes have pores; L. poecilochromus, in which only adult males have pores, and L. neuquensis, in whi.
