Recruitment in Swarm-Founding Wasps:Polybia occidentalisDoes not Actively Scent-Mark Carbohydrate Food Sources

Genetic effects on task performance, but not on age polyethism, in a swarm-founding eusocial wasp

Division of labour among workers in insect societies often includes two major components: age-related changes in behaviour (age polyethism) and specialization in task performance. The aim of this study was to test whether similarity in inside-nest task performance and in rate of age polyethism correspond to genetic similarity among nestmates in the polygynous eusocial wasp Polybia aequatorialis...

Food Carbohydrate Chemistry

The reactions of sugars that are critical in food science applications can be organized into a few general types of reactions that are heavily influenced by pH. Although there are a few exceptions, most of these reactions occur under the relatively mild conditions that prevail during processing and storage. This chapter will not address reactions of chemical synthesis and sugar structure proof....

Social behavior, chemical communication, and adult neurogenesis: studies of scent mark function in Podarcis wall lizards.

Lacertid lizards have been hailed as a model system for the study of reptilian chemical communication. However, results obtained with the genus Podarcis, a diverse group of wall lizards with complex systematics, challenge emerging paradigms and caution against hasty generalizations. Here we review the available evidence on the role of chemical stimuli in male-female and male-male interactions i...

Carbohydrate intake and food sources of junior triathletes during a moderate and an intensive training period.

The study was conducted to investigate the quantity and the main food sources of carbohydrate (CHO) intake of junior elite triathletes during a short-term moderate (MOD; 12 km swimming, 100 km cycling, 30 km running per wk) and intensive training period (INT; 23 km swimming, 200 km cycling, 45 km running per wk). Self-reported dietary-intake data accompanied by training protocols of 7 male tria...
