Diet and body temperature in mammals and birds
Aim We test the hypothesis that endotherm body temperature varies with diet. Location Global terrestrial ecosystems Methods We compile data from the literature on diet and body temperature in mammals and birds. We analyse these and demonstrate global macrophysiological patterns. Results In mammals, carnivores overall have a lower mean body temperature (Tb) than either herbivores or omnivores. H...
متن کاملPREDATION IN MULTI-PREY/ MULTI-PREDATOR COMMUNITIES OF LARGE MAMMALS Seeking common patterns between North America and Africa
The impact that large mammalian carnivores can have on the abundance of their ungulate prey remains contentious and achieving scientific consensus has proved elusive. Several studies in temperate latitudes in North America have documented how increases in the abundance of wolves have been associated with declines in the abundance of certain large ungulate species, and vice versa. In contrast, i...
متن کاملTempo of trophic evolution and its impact on mammalian diversification.
Mammals are characterized by the complex adaptations of their dentition, which are an indication that diet has played a critical role in their evolutionary history. Although much attention has focused on diet and the adaptations of specific taxa, the role of diet in large-scale diversification patterns remains unresolved. Contradictory hypotheses have been proposed, making prediction of the exp...
متن کاملDigestive Strategies of Mammals
Understanding an animal’s nutritional niche is fundamental to a full appreciation of its ecology , and is important for both pest control and species conservation purposes. Carnivores have digestive systems dominated by the small intestine , which can be related to the generally high digestibility of their food. Omnivores have more complex gastrointestinal tracts , with a hindgut caecum in whic...
متن کاملStrong positive effects of termites on savanna bird abundance and diversity are amplified by large herbivore exclusion
Vast areas of the African savanna landscapes are characterized by tree-covered Macrotermes termite mounds embedded within a relatively open savanna matrix. In concert with termites, large herbivores are important determinants of savanna woody vegetation cover. The relative cover of woody species has considerable effects on savanna function. Despite the potentially important ecological relations...
