Spontaneous Emergence of a Relationship between Habitat Openness and Mean Group Size and its Possible Evolutionary Consequences in Large Herbivores

摘要: Abstract Group size generally increases with habitat openness in large mammalian herbivores, be it within species or across a given taxonomic family when considering the typical and herd of each species. This correlation is often considered to adaptive outcome selective pressures arising from predation intraspecific competition that communal foraging may entail. However, increase group openness, occurs species, might simple consequence instability groupings increasing possibility perceiving congeners environment openness. shown present paper through outcomes model for fusion splitting-up, which assumes individuals behave independently Some possible evolutionary consequences phenomenon are discussed.
