Sentence examples for mating resources from inspiring English sources

Our work adds to these studies by showing that when all components of sexual selection are allowed to operate (without intervention) during competition for mating resources, there is an immediate, adaptive effect on male fitness.

Although invertebrate studies that experimentally eliminate sexual selection using enforced monogamy show that broad-sense sexual selection has strong and deleterious effects on offspring fitness, these studies lack a critical feature of normal breeding systems: competition for mating resources.

These data suggest that sexually selected phenotypes are lost during standard laboratory breeding procedures, but are quickly regained when all components of sexual selection are allowed to operate during social competition for mating resources.

Biased ASRs are adaptations to the environment on different scales, resulting from different mechanisms such as inbreeding, mating behaviour, resource limitations, endosymbionts such as Wolbachia, and changes in density or spatial distribution.

Antipredator behaviours are energetically expensive and reduce time available for other important activities such as foraging, mating and resource defence [1], [2].

Although these costs are small compared to those suffered by females mating in resource based polygyny, they are all associated with significant decreases in reproductive fitness.

The act of mating changes the resources required for an individual (Markow et al. 1999), potentially making the decision to stay on a resource or to leave in search of superior resources critically important.

As with many insect species, male and female damselflies differ in life-history strategies: males appear to forage to obtain enough resources for mating activity whereas females forage to obtain greater resources for egg production and thereby gain weight during maturity [ 30].

SAC of territory size can be further increased if territory size is also a function of the amount of available resources (e.g., mating partners or food) and if those resources are themselves spatially autocorrelated at a scale larger than the scale of territory size (e.g., resources distributed along a gradient or in large patches across the study area).

Male reproductive success in many mammals depends on their ability to allocate sufficient energetic resources to mating competition.

Males and females mate promiscuously, with males providing no resources during mating [ 48].
