Sympatric congeneric anurans exist together under systems of adjustment to coexistence of
their populations, systems that reflect a past history of the populations under allopatry and�…

Analysis of the mating call is useful for the study of evolutionary problems in anuran
amphibians because characteristics of the call are chiefly related to the functions of�…

Additional evidence has accumulated over the past 20 years regarding the significance of
the anuran mating call and regarding reinforcement of this premating isolating mechanism�…

Temporal patterns of anuran reproduction fall into two broad categories: prolonged breeding
and explosive breeding. The spatial and temporal distribution of females determines the�…

MUCH of the social behaviour of amphibians, like that of most other ectothcrmic vertebrates,
is centered on reproductive activities. Unlike many birds and mammals, adult amphibians�…

The general categories of non-morphological characters we are concerned with in anurans
are ones that might be expected to be important in any bisexual groups of animals. They�…

The social behaviour of frogs and toads (anuran amphibians) is currently receiving a great
deal of attention from behavioural ecologists. Certain aspects of their mating behaviour�…

Publisher Summary This chapter illustrates the development of genetic differences that lead
to hybrid inviability. It is pointed out that the species level of divergence can be reached with�…

Evolutionary divergence among animal courtship signals is an important component of the
speciation process. In anurans, the preferential response of females to the mating call of�…

From literature data on 116 taxa crosses involving 46 species of frogs, we found a positive
correlation between degree of divergence (measured as Nei's genetic distance, D) and�…
