ABSTRACT.- It is well known that lizard species from thermally diverse areas show differ in their use of thermoregulatory behaviors as a means of making short-term adjustments to differences in ambient conditions.. In contrast, the extent of long-term adjustments in thermal physiology is poorly documented and still under debate. In this study we report a clear relationship between heating rates and environmental temperatures among eight species in a homogeneous clade of lacertid lizards. Phylogenetically-based analyses of covariance demonstrates that species with a northern or montane distribution warm at a faster mass-specific rate than lacertid species from a southern (Mediterranean) climatic zone. Correlational analyses using independent contrasts confirm that mass-specific heating rates increase with environmental temperatures at the lizards' capture site. A reduction of the time spent warming, associated with higher heating rates, should be especially advantageous for lizards from cool climates, which bask for large amounts of time. Thus, we suggest that the relation between heating rate and climatic conditions could be a result of adaptive evolution. The behaviorally-selected preferred temperatures were lower, but not significantly so, in the northern/montane species set; interspecific correlations with ambient temperatures were positive, but not significant. However, the divergence of heating rates and the statistically nonsignificant difference in preferred temperatures have similar impacts in the estimated amount of time spent heating. Thus, differences in both heating rate, a physiological trait, and preferred temperature, a behavioural characteristic, contribute equally to variation in heating times.

ABSTRACT.- I studied the activity, spacing patterns, courtship behavior and survival of males (classified into two groups according to the development of the head's sexual coloration) and females from a population of the lacertid lizard Psammodromus algirus. Brightly colored (C+) males were significantly larger (and probably older) than dully colored (C-) males, but the results related to behavioral aspects differed between study years. In 1989, C+ males had larger home ranges, were more active, overlapped more females and courted them more frequently than C- males. In 1990, none of these traits differed between the two male categories. The variables associated with survival were different in the two sexes. Larger and more active males survived less well than smaller and less active ones, whereas for females survival was associated with later observation times during the day. Mortality could be due to a higher predation risk affecting animals that were active more days or under less favorable conditions. I postulate that the increased activity of males (mainly C+ category in years favoring stronger selection) would increase their short-term reproductive success but negatively affect their survival.

Zoología. Aproximación evolutiva a la diversidad y organización de los animales Este manual presenta un amplio repaso de las causas históricas y actuales que explican la diversidad y organización de los animales y su adaptación al ambiente en que viven. El libro se estructura en dos partes: en la primera se desarrollan los conceptos evolutivos más importantes para el zoólogo y sus métodos de estudio, y la segunda es un resumen de la historia evolutiva de los animales. Se diferencia de los grandes manuales de Zoología en que su enfoque es sobre todo funcional, con un esquema de Zoología Sistemática, o historia de la diversidad y organización de los animales, trabado por las aportaciones conceptuales de la moderna Biología Evolutiva. |
