Abstract

The available information on capybara (Hydrochoerus hydrochaeris) meat, an important resource for the subsistence of many traditional communities in several South American countries, is reviewed. Some features of the species, such as an herbivorous diet, high prolificacy, rapid growth rate,...

Abstract

Kin selection theory has received some of its strongest support from analyses of within-colony conflicts between workers and queens in social insects. One of these conflicts involves the timing of queen production. In the neotropical (Venezuelan) vespid wasps, Parachartergus colobopterus, Polybia...

Abstract

Social groups of capybaras averaging 10 adults contained a mean of 3.6 adult ♂♂. Of 2911 interactions observed within social groups of capybaras, 34% were among adult ♂♂, and these were invariably aggressive. Males were organized in stable, linear hierarchies. The dominant ♂ in each group was...

Abstract

It was found that genetic relatedness among P. occidentalis workers from Venezuela was 0.26±0.057, a value high enough to make altruistic behaviour by workers relatively easy to explain. This comparatively high level of relatedness can be attributed to close relatedness among queens of 0.57±0.077...

Abstract

The maintenance of sociality is most difficult to explain under circumstances where non-reproducing helpers are physiologically capable of reproducing and distantly related to the brood they rear. The Neotropical swarm-founding wasps are likely to fulfil these conditions because most taxa lack...

Abstract

Colony foundation was studied in colonies of Atta laevigata collected from the field in Venezuela during October 1988. In a colony with 2 foundresses, workers attacked and killed both foundresses 3 months after collection from the field. Similar behaviour was not observed in colonies with single...
