In both pipefishes and seahorses, males receive the eggs from the female, fertilize them, protect them within a pouch, and give birth to the offspring (see below). For example, female great reed warblers (Acrocephalus arundinaceus) have a preference to mate with males with larger song repertoires, because this indicates that they are older and may have better nesting territories.

In some cases, polygyny can lead to aggression between males. Inmonogamoussystems, one male and one female are paired for at least one breeding season. There are many different types of adaptations in different species to maximize biological fitness, includingparental investment,direct male competition, andindirect male competition. However, polygyny is not a particularly beneficial mating system for females, because their mate choice is limited to one male. This behavior demonstrates that the females are protecting their breeding male from intruding females, suggesting they are preventing female access to a desirable mate. The uncertainty of not knowing whos the daddy selects for males to avoid infanticide, as they may inadvertently kill their own offspring. Can expand your gene pool.

[8] Because females do not need extra help raising their nests, males can afford to invest in multiple females. While there are many non-mutually exclusive hypotheses to explain selection for monogamous mating systems, one prominent explanation is themale-assistance hypothesis, where males that remain with a female to help guard and rear their young will have more and healthier offspring. A mating system describes how males and females pair when choosing a mate. The Advantages of Polygamy. Benefits include the (relative) certainty of access to the partner's reproductive potential, but the chief disadvantage is that access to other potential partners is strongly diminished, particularly in those cases where males exhibit strong mate-guarding behavior.

Sexual selection is the driving force that underlies the evolution of male competition and female choice, but what ecological factors contribute to one species having highly ornamented males and another having no differentiation between the sexes.Not all species show strong sexual dimorphisms. The female disadvantages of mating with an already-mated male bird can be overcome with ample resources provided by the male, resulting in female choice.
