Mate sampling and choosiness in the sand goby.
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 testing how latency to mate is affected by various search costs, variation in mate quality and female quality in the sand goby (Pomatoschistus minutus). Our results show that females adjust their mating behaviour accordin...

متن کاملSurprising similarity of sneaking rates and genetic mating patterns in two populations of sand goby experiencing disparate sexual selection regimes.
Molecular markers have proved extremely useful in resolving mating patterns within individual populations of a number of species, but little is known about how genetic mating systems might vary geographically within a species. Here we use microsatellite markers to compare patterns of sneaked fertilization and mating success in two populations of sand goby (Pomatoschistus minutus) that differ dr...
متن کاملEnergetic Constraints on Species Coexistence in Birds
The association between species richness and ecosystem energy availability is one of the major geographic trends in biodiversity. It is often explained in terms of energetic constraints, such that coexistence among competing species is limited in low productivity environments. However, it has proven challenging to reject alternative views, including the null hypothesis that species richness has...
متن کاملEcological Constraints on Mating Tactics
Mating tactics do not exist in a vacuum. Rather, they develop within specific environmental contexts. Such contextual influences can be conceptualized as a series of concentric circles around the individual, as in Bronfenbrenner’s (1979) ecological model of behavioral development, that are hierarchically nested within each other like a set of Russian dolls. Bronfenbrenner placed behavioral deve...
