The aim of this review is to consider the potential benefits that females may gain from mating
more than once in a single reproductive cycle. The relationship between non-genetic and …

Rapid evolutionary radiations provide insight into the fundamental processes involved in
species formation. Here we examine the diversification of one such group, the cichlid fishes …

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 …

▪ Abstract Fish species have diverse breeding behaviors that make them valuable for testing
theories on genetic mating systems and reproductive tactics. Here we review genetic …

Alternative reproductive tactics (ARTs) coexisting within a population are found in many
organisms. Their existence has been an enduring puzzle in evolutionary biology. Why …

Alloparental care, care directed at non-descendant young, presents a potential challenge to
evolutionary ecologists because investment in non-descendant eggs and young gives the …

The characterization of patterns of multiple mating is a major facet of molecular ecology and
is paramount to understanding the evolution of behaviours associated with parental care …

Molecular analyses of bird and mammal populations have shown that social mating systems
must be distinguished from genetic mating systems. This distinction is important in fishes …

We compared pairs of closely related taxa of cichlid fishes from Lake Tanganyika to examine
the relationship between sperm size and the presumed intensity of sperm competition. In …

Fry production in Nile tilapia, Oreochromis niloticus is typically achieved by mass spawning
of males and females stocked in large hapas suspended in ponds. In such spawning …
