Natural selection on testosterone production in a wild songbird population.
Because of their role in mediating life-history trade-offs, hormones are expected to be strongly associated with components of fitness; however, few studies have examined how natural selection acts on hormonal variation in the wild. In a songbird, the dark-eyed junco (Junco hyemalis), field experiments have shown that exogenous testosterone alters individuals' resolution of the survival-reprodu...
متن کاملNatural and sexual selection in a wild insect population.
The understanding of natural and sexual selection requires both field and laboratory studies to exploit the advantages and avoid the disadvantages of each approach. However, studies have tended to be polarized among the types of organisms studied, with vertebrates studied in the field and invertebrates in the lab. We used video monitoring combined with DNA profiling of all of the members of a w...

متن کاملNatural selection on molar size in a wild population of howler monkeys (Alouatta palliata).
Dental traits have long been assumed to be under selection in mammals, based on the macroevolutionary correlation between dental morphology and feeding behaviour. However, natural selection acting on dental morphology has rarely, if ever, been documented in wild populations. We investigated the possibility of microevolutionary selection on dental traits by measuring molar breadth in a sample of...
متن کاملNatural selection in the wild.
C an evolution by natural selection be summed up in a single number? Perhaps not, but the number that comes closest is the additive genetic variance of fitness (V w 2). This is the amount by which natural selection increases mean fitness every generation 1. It also appears in equations for the change in any character as a result of natural selection 2 ; in equations for the selective advantage ...
