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 …

Nests are the key elements of the reproductive repertoire of several fish species.
Understanding the physiological aspects behind their nesting behaviour is imperative to …

Our understanding of sexual selection has greatly improved during the last decades. The
focus is no longer solely on males, but also on how female competition and male mate …

Prostaglandins (PGs) are a type of physiologically active unsaturated fatty acids. As an
important sex pheromone, PGs play a vital role in regulating the reproductive behaviors of …

The strength of sexual selection may vary between species, among populations and within
populations over time. While there is growing evidence that sexual selection may vary …

Parental care is a rather common reproductive strategy in fishes, particularly in species with
low fecundity and large eggs as the Antarctic icefish (Channichthyidae). The infrequent use …

Sexual selection can be affected by the competition for limited breeding resources and/or
the competition for limited mates. Although there is ample evidence for each type of …

abstract Sexual selection influences the evolution of phenotypic traits and contributes to
patterns of biodiversity. In many animals, mating involves sequential steps. Often, individuals …

In many species, the natural distribution of material resources important for reproduction can
profoundly impact reproductive success among individuals and, hence, the opportunity and …

The operational sex ratio (OSR, ready-to-mate males to females) is a key factor determining
mating competition. A shortage of a resource essential for reproduction of one sex can affect …
