In a microchromosome-carrying laboratory stock of the normally all-female Amazon molly Poecilia formosa triploid individuals were obtained, all of which spontaneously developed into males. A comparison of morphology of the external and internal insem

Female choice can often drive the elaboration of male traits, leading to the evolution of secondary sexual traits. In the Mexican molly, Poecilia sphenops (Poeciliidae), some males exhibit a mustache-like structure on the upper maxilla, the function

According to predictions based on recent foraging theory, animals encountering two or more patches that contain the same prey type at different densities should choose the higher density patch. If detectability varies among patches, foragers should t

The aggressive behaviour of hybrids between an epigeous and a cave-dwelling form of the toothcarp Poecilia sphenops was investigated in order to test whether a genetically determined reduction of aggressive behaviour exists in the cave population. Th

The chemical communication of the epigean Necturus maculosus and the cave-living Proteus anguinus are compared in laboratory conditions. In both species a specks-specific substance transferred by water could be shown, another was deposited on the sub

The inheritance of sexual behaviour patterns was studied in species hybrids of Poecilia mexicana and Poecilia velifera. In addition, the aggressive behaviour and some morphological characters have been investigated and checked for a possible correlat

Chemical information is known to be of great importance to cave animals in their lightless biotope. ♂ ♂ ♀♀, and subadults of the cave salamander Proteus anguineus were kept in darkened aquaria and studied using infra-red in order to determine

Summary The Amazon molly, Poecilia formosa, is a gynogenetic, all-female fish. Its mating system relies on heterospecific matings with males of closely related sexual species. In mixed populations, males mate with conspecific sexual females and heter
