The study of genetic exchange resulting from natural hybridization, horizontal gene transfer,
and viral recombination has long been marked by controversy between researchers holding …

Knowledge of the genetic mating system of animal species is essential for our
understanding of the evolution of social systems and individual reproductive strategies. In …

Gibbons or small apes constitute the primate family Hylobatidae and are, besides the great
apes, humans' closest living relatives. Due to an increase in studies on wild and captive …

Objectives It has long been recognized that in gibbons both sexes disperse from the natal
group. However, the fate of dispersed individuals was rarely documented. Here we provide …

Interspecific hybridization in primates is common but hybridization between distantly related
sympatric primate species is rarely observed in the wild. We present evidence for a possible …

Hybridization is increasingly recognized as an important mechanism of evolutionary change
in the order Primates. Here, we present the first observational data supporting natural …

Aggressive behaviors are widespread among territorial species and asymmetrical
aggressiveness may imply differential access to resources. At a larger scale, such …

Gibbons of the genus Hylobates, which inhabit Southeast Asia, show great diversity and
comprise seven to nine species. Natural hybridisation has been observed in several species …

Gibbons (Family Hylobatidae) are a suitable model for exploring hybridization in pair-living
primates as several species form hybrid zones. In Khao Yai National Park, Thailand, white …

Objectives The study of related species in contact zones can elucidate what factors mediate
species coexistence and geographical distributions. We investigated niche overlap and …
