Mechanisms of thermal balance in flying Centris pallida (Hymenoptera: Anthophoridae).
Thermoregulation of the thorax is critical for bees and other endothermic insects to achieve high rates of flight muscle power production. However, the mechanisms allowing insects to regulate thorax temperatures during flight are not well understood. To test whether variations in metabolic heat production, evaporation or heat transfer from the thorax to the abdomen contribute to the maintenance...
متن کاملNovas políticas de divisão de nós para a Slim-tree
This paper presents two new node split policies for the Slim-tree. When compared with the previously proposed policies they result in better distribution of elements on the tree nodes. This impacts positively on the performance of similarity queries such as nearest neighbors. The experimental results show that trees built with the proposed policies outperform those built with the above with reg...
متن کاملUnexpected Polylecty in the Bee Genus Meganomia (Hymenoptera: Apoidea: Melittidae)
The melittid bees represent an early branch of bee phylogeny. They are therefore of special interest in understanding the early evolution and diversification of bees. Most species have been observed to be oligolectic (i.e., highly specialized in their choice of host-plant species). However, knowledge of host-plant associations is not equivalent across all melittid groups. Dasypodainae and the M...
