Carotenoids are among the most prevalent pigments used in animal signals and are also
important for a range of physiological functions. These concomitant roles have made …

Empirical studies of sexual traits continue to generate conflicting results, leading to a
growing awareness that the current understanding of this topic is limited. Here we argue that …

Sexual selection driven by mate choice has generated some of the most astounding
diversity in nature, suggesting that population-level preferences should be strong and …

Selection on advertisement signals arises from interacting sources including female choice,
male–male competition, and the communication channel (ie, the signaling environment). To …

Background Parental allocation and reproductive success are often strongly influenced by
environmental factors. In this respect, salinity is a key factor influencing species distributions …

Fisheries often combine high mortality with intensive size selectivity and can, thus, be
expected to reduce body size and size variability in exploited populations. In many fish …

Phenotypically plastic mating behavior may allow males to modify their reproductive
behavior to suit the prevailing social conditions, but we do not know if males only react to …

In principle, temporal fluctuations in the potential for sexual selection can be estimated as
changes in intrasexual variance in reproductive success (ie the opportunity for selection) …

To date, mate choice studies have mostly focused on establishing which mates are chosen
or how the choices are performed. Here, we combined these two approaches by empirically …

Very few studies have presented compelling evidence for adaptive shifts in female mating
preferences. Additionally, there is almost no data on how males adjust courtship effort when …
