Male-male competition magnifies inbreeding depression in wild house mice.
The detrimental effects of inbreeding on vertebrates are well documented for early stages of the life cycle in the laboratory. However, the consequences of inbreeding on long-term survival and reproductive success (Darwinian fitness) are uncertain for vertebrates in the wild. Here, we report direct experimental evidence for vertebrates that competition increases the harmful effects of inbreedin...
متن کاملSubjective well-being and 'male depression' in male adolescents.
BACKGROUND The concept of male depression is based on the hypothesis that typical symptoms of depression in men often seem to be masked by non-typical male distress symptoms not considered in common depression inventories. Although there is a large amount of clinical evidence, scientific evidence is still lacking. The study aims at further validating the concept of male depression, by obtaining...
متن کاملInbreeding depression in male gametic performance.
One key objective in evolutionary ecology is to understand the magnitude of inbreeding depression expressed across sex-specific components of fitness. One major component of male fitness is fertilization success, which depends on male gametic performance (sperm and pollen performance in animals and plants, respectively). Inbreeding depression in male gametic performance could create sex-specifi...
متن کاملMeasuring postinjury depression among male and female competitive athletes.
Depression is common among athletes following sport injury, yet few studies have explored the severity of postinjury depression. Among those studies, only one examined gender differences although women in the general population are more likely than men to experience depression. No research to date has used interviews to assess depression despite their standard use among mental health profession...
متن کاملInbreeding depression and male fitness in black grouse.
The male lifetime lekking performance was studied, and related to inbreeding-outbreeding in a wild population of black grouse (Tetrao tetrix) in central Finland between 1989 and 1995. Inbreeding was measured as the mean heterozygosity and mean d(2) of 15 microsatellite loci. We found a significantly positive relationship between mean d(2) and lifetime copulation success (LCS), while the relatio...
