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 …

In this paper we review functional and evolutionary relationships among mating systems of
caridean shrimp and specific traits such as general biology/ecology, sexual systems …

Animals commonly modify their behavior in the presence of a conspecific or in response to
signals. This is particularly true in the context of aggressive exchanges, which animals use …

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

Dominance hierarchies have been well studied in myriad terrestrial animals, but surprisingly
little is known about hierarchies in marine invertebrates; examples are limited to a few …

Identifying correct stocking densities is an important concern for shrimp farming especially
when intensification of shrimp production is growing in order to meet increasing demand …

Across group-living animals, linear dominance hierarchies lead to disparities in access to
resources, health outcomes and reproductive performance. Studies of how dominance rank …

Ontogenetic changes in the relative growth of males and females of the spider crab Maja
brachydactyla, a species with terminal moult and determinate growth, were analysed and …

This book explores the biology of decapod shrimps, a group of animals known to most
people as a nutritious and tasty food item. Shrimps are amazingly diverse in size, shape …

Mate searching in crustaceans depends on different communicational cues, of which
chemical and visual cues are most important. Herein we examined the role of chemical and …
