| do female reproductive stage and phenotype influence thermal requirements in an oviparous lizard? | reproduction is an energetically costly activity that can alter thermal requirements in squamata. this phenomenon has been largely studied in many viviparous species; however, little is known about the role of oviparous females in controlling temperature during vitellogenesis and embryo development before oviposition. diversity of female phenotypes could be associated with diversity of thermoregulatory performance, since thermal requirements are frequently influenced by body shape. furthermore, ... | 2018 | 29301691 |
| sexual dichromatism and color diversity in the spiny lava lizard tropidurus spinulosus using lizard visual modelling. | colors are important vehicles for social signals in many taxa. in squamata, previous studies have linked color characteristics and chromatic diversity to sexual selection and, particularly, species showing male-biased body size dimorphism also showed male-biased dichromatism and color diversity. sexual dichromatism may occur in body regions used for conspecific communication and it may be expressed at wavelengths, such as ultraviolet, easily perceivable by conspecifics. we tested this prediction ... | 2019 | 31582783 |
| electrostimulation is an effective and safe method for semen collection in medium-sized lizards. | the development of safe and consistent semen collection protocols should be ensured to understand basic sperm parameters of a species. electroejaculation has been hypothesized and tested to be a safe method to evaluate male reproductive potential in wild animals. however, little is known about semen collection protocols in lizards. adjusting stimulation to species and body mass is important for efficient semen collection as well as for animal welfare. tropidurus spinulosus is a good model to ada ... | 2018 | 29883843 |
