Among vertebrates, fish show by far the greatest variability of alternative reproductive tactics
(ARTs). Usually, males attempting to monopolize access to females or fertilizations are …

The occurrence of intra-sexual variation in reproduction is a widespread phenomenon in
teleosts. One such form of variation consists in the occurrence of alternative male types …

Female mimics are known from many species, but permanent, non-conditional, alternative
mating strategies are only known from an isopod, a fish, a lizard and a bird. The single bird …

With over 20,000 species described to date, teleost fish are the most diverse taxon of living
vertebrates, representing a very successful lineage of recently evolved organisms (Nelson …

Fishes have radiated throughout all aquatic environments, and this is reflected in an
extraordinary diversity of mating systems and reproductive behaviors. Many species present …

Fish reproductive biology (onset and duration of spawning, sex ratio, maturity stages, length
and age at maturity, and fecundity) is important in fisheries research, stock assessment, and …

In the peacock blenny Salaria pavo large males with well-developed secondary sexual
characters establish nests and attract females while small “sneaker” males mimic female …

Of all vertebrates, fish exhibit unparalleled diversity of sexual plasticity and flexibility, ranging
from gonochorism to unisexualism, and exceptional patterns of functional hermaphroditism …

The wide diversity of alternative tactics of reproduction found among vertebrates offers a
unique opportunity to study the endocrine mechanisms underlying the phenotypic variation …

Mating systems of species result from a complex interaction of phyloge ne tic constraints and
