Therefore a valid conceptual model is essential in all those information systems representing evolution of territorial forms and functions.
The sex-independent effect of body size on competitive success is consistent with a role of territorial competition in the evolution of sexually monomorphic body size in the Tropheus lineage.
This, in turn, could eventually lead to the evolution of greater territorial aggression in hermit warblers and less territorial aggression in Townsend's warblers, and ultimately halt the hybrid zone movement we document here.
In this framework, we focus on the interaction between the Italian labour market and welfare characteristics in shaping the likelihood of being persistently poor, according to households' main earner source of income and gender, as well as the temporal evolution of the territorial dualism during the crisis.
Following the evolution of female territoriality in Tropheus, selection ensuing from territorial competition could then have driven the evolution of monomorphic body size.
The identification of future landscape scenarios is based on the integration of past evolution (historical analysis), landscape sensitivity (territorial analysis) and farmers' adaptation to market and policy changes (farm analysis).
Specifically, the study tracks the evolution of early ceremonial centers, Teotihuacan's territorial expansion through the region, political balkanization following the collapse of Teotihuacan, and the establishment of small, independent polities encountered by the Spanish.
Social selection arising from territorial competition could be a common mechanism underlying the evolution of sexually monomorphic body size and coloration in this lineage.
"But it's equally possible," he said, that territorial aggression becomes less advantageous at certain stages of human evolution, so that it died out and re-emerged in humans later.
Territoriality therefore causes reproductive skew between territorial breeders and non-territorial non-breeders.
