In many animal species, males may exhibit one of several discrete, alternative ways of
obtaining fertilisations, known as alternative reproductive tactics (ARTs). Males exhibiting …

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 Gobiiformes is one of the most diverse orders of the Percomorphs, with approximately
2000 species in 270 genera. They represent 5 to 10% of all teleosts, with species occurring …

Males that exhibit alternative reproductive tactics (ARTs) often differ in the risk of sperm
competition and the energetic trade-offs they experience. The resulting patterns of selection …

Sperm competition theory predicts that males should strategically allocate their sperm
reserves according to the level of sperm competition, defined as the probability that the …

Morphological character analyses indicate that Rhyacichthyidae, Odontobutidae, Eleotridae,
and Xenisthmidae are the basal families within the perciform suborder Gobioidei. This study …

Although the round goby, Neogobius melanostomus, is widespread in the Great Lakes and

The changes in a marine community in the northern Adriatic Sea were explored over a
period of 65 years using landings data from a commercial fishing fleet, and the role of fishing …

Seminal fluid often makes up a large part of an ejaculate, yet most empirical and theoretical
studies on sperm competition have focused on how sperm characteristics (number and …
