A great deal of information is known regarding the process of sex differentiation in fish, and
the mechanisms involved in primary sex determination are now beginning to be defined. A …

Teleost fishes are characterized by a diversity of sexual patterns. Hermaphroditism, the
expression of both male and female reproductive function in a single individual, generates …

Mbuna, the dominant fishes on the rocky shores of Lake Malawi, have become a major
'model system'for the study of rapid speciation and adaptive radiation. At least 295 putative …

Van Valen (1973) characterized evolution as the control of development by ecology. Sex
determination in fishes provides some clear examples of this “control” in operation. Teleost …

The distribution of hermaphroditism in fishes has traditionally been mainly explained by its
dependence on biotic factors. However, correlates with major abiotic factors have not been …

Studying environmental sex determination (ESD) in cichlids provides a phylogenetic and
comparative approach to understand the evolution of the underlying mechanisms, their …

The unprecedented level of diversity recorded among the clones of self-fertilizing
gynogenetic unisexuals and self-fertilizing simultaneous hermaphrodites challenges current …

Genetic and environmental factors may interact to control sex determination in fishes. A
common pattern of initial female differentiation and subsequent male transformation before …

This book is the first to report that research in allogenics/xenogenics has conclusively shown
that fishes have retained bisexual potency even after sexual maturity and spermiation. The …

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