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
Patterns of morphological diversification of mainland Anolis lizards from northwestern South America
TL;DR: This work uses a large morphological data set and a molecular phylogeny to describe the morphological diversification of anoles from northwestern South America, and demonstrates convergence between mainland morphotypes and Caribbean ecomorphs, which suggests that common processes are driving both radiations.
Journal ArticleDOI
Evolution of egg retention in the sceloporus spinosus group: exploring the role of physiological, environmental, and phylogenetic factors
TL;DR: Mapping the maximum stage at oviposition on a phylogeny of the S. spinosus group suggested that the invasion of high elevations was associated with an enhanced potential for longer periods of egg retention, and females exhibited the ability to retain eggs as predicted.
Journal ArticleDOI
Reproductive Activity of Three Sympatric Viviparous Lizards at Omiltemi, Guerrero, Sierra Madre del Sur, Mexico
Martha Patricia Ramírez-Pinilla,Martha L. Calderón-Espinosa,Oscar Flores-Villela,Antonio Muñoz-Alonso,Fausto R. Méndez-de la Cruz +4 more
TL;DR: This convergence in reproductive patterns suggests a common evolutionary response to environmental factors associated with montane habitats, whereas specific differences observed within species are attributed to the particular evolutionary history of each taxon.
Journal ArticleDOI
Molecular phylogenetics and biogeography of the Neotropical skink genus Mabuya Fitzinger (Squamata: Scincidae) with emphasis on Colombian populations.
Nelsy Rocío Pinto-Sánchez,Martha L. Calderón-Espinosa,Aurélien Miralles,Andrew J. Crawford,Andrew J. Crawford,Martha Patricia Ramírez-Pinilla +5 more
TL;DR: The diversity of Mabuya within Colombia is higher than previously recognized, and includes lineages from Central America and from eastern and southern South America, and the genus appears to have originated in eastern South America in the Early Miocene.
