The aim of this review is to consider variation in mating preferences among females. We
define mating preferences as the sensory and behavioural properties that influence the …

S exual selection has been such an intensive focus of research over the past decade that
one might expect there to be a well-established answer to the question posed in our title. On …

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 …

Advantages of dispersal on the scales that are possible in a long pelagic larval period are
not apparent, even for benthic species. An alternative hypothesis is that wide dispersal may …

Understanding how individuals select mates becomes complex when high–quality
conspecifics resemble heterospecifics. Individuals facing such a situation may be unable to …

Theories about sexual selection can be traced back to Darwin in 1871. He proposed that
males fertilize as many females as possible with inexpensive sperm, whereas females, with …

According to mate choice models, a female should prefer males with traits that are reliable
indicators of genetic quality which the sire can pass on to their progeny. However, good …

Sockeye salmon Oncorhynchus nerka sperm maintained high fertility for 10 s after being
exposed to water but fertility dropped sharply after that. Eggs also showed limited longevity …

The study of alternative reproductive behaviors in fishes has contributed to our general
understanding of reproductive strategies and mating systems. Despite extensive research …

Among ray-finned fishes that provide parental care, many spawn in constructed nests,
ranging from bowls, burrows and ridges to nests made of algae or bubbles. Because a nest …
