Isolating Mechanisms and Interspecies Interactions in Anuran Amphibians

摘要: Sympatric congeneric anurans exist together under systems of adjustment to coexistence their populations, that reflect a past history the populations allopatry and also interspecific interactions subsequent sympatry. species may affect one another through mismating even when genetic interchange is barred by hybrid sterility or inviability. Several isolating mechanisms usually operate restrict hybridization any given pair sympatric anurans, with difference in mating call paramount importance. Some important parameters (viz., frequency pulse rate) are functions body size, hence differentiation these attributes be secondary effect adaptive size. Other appear have been subject selection per se. Ecological represent side-products adaptation different ways life allopatric populations. Postmating mechan...
