Growth Ecology of the Lizard Xenosaurus grandis in Veracruz, México
Abstract We analyzed variation in growth in the lizard Xenosaurus grandis in a seasonal tropical environment in Veracruz, México. We used the logistic-by-length model to represent the growth patternExpand

Analysis of the Population Dynamics of an Endangered Lizard (Xenosaurus Grandis) through the Use of Projection Matrices
Abstract We conducted a demographic analysis from 2000 to 2004 of a population of the crevice-dwelling lizard, Xenosaurus grandis, in Veracruz, México. We used population projection matrices to modelExpand

Differential mortality drives life-history evolution and population dynamics in the fish Brachyrhaphis rhabdophora.
Life-history theory predicts that populations experiencing different levels of extrinsic mortality will evolve divergent reproductive strategies. Previous work in the live-bearing fish BrachyrhaphisExpand

Morphological and reproductive variation among populations of the Pacific molly Poecilia butleri.
In viviparous organisms, pregnant females typically experience an increase in body mass and body volume. In this study, the prediction that variation in reproductive traits among populations ofExpand

A test of the fast-slow continuum model of life-history variation in the lizard Sceloporus grammicus
Background: The fast–slow continuum hypothesis (Promislow and Harvey, 1990) suggests that mortality rates are a strong selective factor that shapes inter- and intraspecific variation in lifehistoryExpand

Patterns of spatio-temporal variation in the survival rates of a viviparous lizard: the interacting effects of sex, reproductive trade-offs, aridity, and human-induced disturbance
Examination of the spatial and temporal variation in survival rates provides insight on how the action of natural selection varies among populations of single species. In this study, we usedExpand

05. Effect of toe-clipping on the survival of several lizard species
Toe-clipping is an extensively used technique for individual identification of amphibians and reptiles. However, this method might result in negative effects including reduced survival. In thisExpand
