Information transfer determined by association of neighbours in European bee-eater (Merops apiaster) colonies
2007
The Information Centre Hypothesis (ICH) and the Two-Strategies Hypothesis (TSH) predict that foraging success is enhanced by information exchanged among individuals within a colony or roost. Nest location within a colony may be critical in this regard, as individuals with abundant, nearby neighbours likely have greater access to information regarding a new food resource than relatively isolated breeders. To determine how the availability of neighbours influences information transfer, we quantified foraging success in a population of European bee-eaters (Merops apiaster) provided with a honey bee (Apis mellifera) hive as a new food resource. To quantify potential information transfer we deve…
Colonial, post-colonial, neo-colonial Mediterranean: historical, archaeological and iconographical sources for a micro-history of an uncomfortable th…

Even in its most neutral meanings, the term “colonial” leads to questioning the cultural and ideological purpose of its use. This also concerns its derivatives, post-colonial and neo-colonial, whose prefixes are not to be interpreted in a merely chronological sense. This paper investigates the remote origins of a mental attitude that has resulted both in a “colonial” reading of some phenomena and in a post-colonial new interpretation. The aim is to highlight the common cultural bases of these two very different conceptions (in theory opposite and non-superimposable). Also, the interpretations which are apparently far from imperialism are not totally immune from the danger of a form of racis…
Social phenotype extended to communities: expanded multilevel social selection analysis reveals fitness consequences of interspecific interactions.
2014
In social species, fitness consequences are associated with both individual and social phenotypes. Social selection analysis has quantified the contribution of conspecific social traits to individual fitness. There has been no attempt, however, to apply a social selection approach to quantify the fitness implications of heterospecific social phenotypes. Here, we propose a novel social selection based approach integrating the role of all social interactions at the community level. We extended multilevel selection analysis by including a term accounting for the group phenotype of heterospecifics. We analyzed nest activity as a model social trait common to two species, the lesser kestrel (Falc…
