The final version of this article published by Elsevier in the Journal of Cognition can be found here: http://www.sciencedirect.com/science/article/pii/S0010027708000772, The accuracy with which previously unfamiliar faces are recognised is increased by the presentation of a stereotype-congruent occupation label (Klatzky, Martin,…

Considerable attention has recently been directed towards the analysis of pluralism in social science, not least in economics. Plurality is often taken as a mark of pluralism. But it is not the same thing, and often indicates little more than…

We conducted a 5 year demographic study in one population of the viviparous lizard Sceloporus grammicus Wiegmann, 1828 in central México. The population was structured in three size classes (juveniles, small adults, and asymptotic adults) for which we estimated annual…

Cactus seedlings often establish under nurse plants which modify environmental conditions by increasing moisture and decreasing solar radiation, which may cause beneficial and detrimental effects, respectively, on seedling growth. Three soil moisture treatments (5%, 25% and 60%) and two solar…

We studied litter size, size at birth, and relative litter mass (RLM) in two populations of the crevice-dwelling lizard Xenosaurus platyceps: one located in a low-altitude tropical forest; and the other in a high-altitude temperate oak forest. We found a…

Basic demographic information for turtles in tropical and sub-tropical regions is still scarce. As a consequence, prospective management and conservation plans for these long-lived vertebrates lack the necessary quantitative background for successful implementation. In this study, we used capture-mark-recapture techniques…

Both females and males may suffer from increased mortality risk as a result of the activities and physiological processes associated with reproduction. In this study I estimated sex-specific reproductive costs in the survival rates of a viviparous and territorial lizard…

Cacti are thought to be highly vulnerable to chronic anthropogenic disturbance (CAD). To assess its effects, we modeled the dynamics of three populations of the endangered cactus Coryphantha werdermannii exposed to different intensities of disturbance. Because no seedlings germinated and…

Verbesina virgata (Asteraceae) is the stable food of generalist herbivores in xerophytic vegetation of southern Mexico City where nitrogen and phosphorous are limiting soil resources for plant growth and therefore it is likely that arbuscular mycorrhizal fungi play an important…

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 of viviparous organisms should be related to variation among populations in body shape…
