Full-text available
Molecular phylogenetic studies based on Sanger sequences have shown that Cyperaceae tribe Fuireneae s.l. is paraphyletic. However, taxonomic sampling in these studies has been poor, topologies have been inconsistent, and support for the backbone of trees has been weak. Moreover, uncertainty still surrounds the morphological limits of Schoenoplectie...
Article
Morphological characterizations of genera in Cyperaceae tribe Abildgaardieae have been highly problematic and the subject of much debate. Earlier molecular phylogenetic studies based on Sanger sequencing and a limited sampling have indicated that several generic circumscriptions are not monophyletic. Here, we provide the first phylogenetic hypothes...

Social behaviour includes a number of intraspecific interactions in the animal life including female choice, species recognition and altruistic behaviour. Among the species displaying social behaviour and highly integrated to the environment are the insects. Bees comprise an ideal group to study the evolution of the social behaviour because they have a great diversity of social life styles that evolved independently. The tribes Apini and Meliponini comprise only highly eusocial species whereas various levels of sociality can be detected in other tribes being most bees indeed solitary. Although the evolution of eusociality has been the subject of many studies, the genetic changes involved in the process have not been completely understood. Results from studies conducted so far provide a starting point for the connection between specific genetic alterations and the evolution of eusocial behaviour. However fundamental questions involved in this process are still open. Recently new sequencing technologies have allowed genetic studies of non model and model organisms in a deep and non-directional way which is promising for the study of the evolution of complex characteristics. In this context, this research project will analyze the gene expression profile from different bee species and stages of development. Our results certainly will improve our understanding of bee social behaviour evolution.
