TL;DR: Global extinction projections were validated with local extinctions observed from 1975 to 2009 for regional biotas on four other continents, suggesting that lizards have already crossed a threshold for extinctions caused by climate change.
Journal ArticleDOI
Continuous spermatogenesis in the lizard sceloporus bicanthalis (sauria: phrynosomatidae) from high elevation habitat of central mexico
Oswaldo Hernández-Gallegos,Fausto R. Méndez-de la Cruz,Maricela Villagrán-Santa Cruz,Robin M. Andrews +3 more
TL;DR: Sceloporus bicanthalis is a viviparous lizard that inhabits high altitude temperate zone habitats in Mexico and exhibits spermatogenesis and spermiogenesis throughout the year as discussed by the authors.
Journal ArticleDOI
Body Temperatures of Female Sceloporus grammicus: Thermal Stress or Impaired Mobility?
TL;DR: It is suggested that the thermal stress and the encumbrance hypotheses are not alternatives but are complementary explanations for the thermal behavior of female Sceloporus.
Journal Article
Gonadal changes throughout the reproductive cycle of the viviparous lizard Scleroporus mucronatus (Sauria : Iguanidae)
Elvira Estrada-Flores,Maricela Villagrán-Santa Cruz,Fausto R. Méndez-de la Cruz,Gustavo Casas-Andreu +3 more
TL;DR: Sceloporus mucronatus is a high altitude viviparous lizard with a seasonal repro- ductive cycle involving distinct periods of gonadal activity followed by an interval of regression and quiescence indicating that germ cell maturation and gonadal cycle are not synchronized between sexes.
Journal ArticleDOI
Reproductive Cycle of the Lizard Sceloporus mucronatus with Comments on Intraspecific Geographic Variation
TL;DR: The longer period of testicular recrudescence (January–July) in the studied population from Tecocomulco suggests plasticity in testicular activity.
