Melanin-specific life-history strategies.
The maintenance of genetic variation is a long-standing issue because the adaptive value of life-history strategies associated with each genetic variant is usually unknown. However, evidence for the coexistence of alternative evolutionary fixed strategies at the population level remains scarce. Because in the tawny owl (Strix aluco) heritable melanin-based coloration shows different physiologic...
متن کاملLife-History Theory: Fast and Slow Strategies
Just as modern economies undergo periods of boom and bust, human ancestors experienced cycles of abundance and famine. Is the adaptive response when resources become scarce to save for the future or to spend money on immediate gains? Drawing on life-history theory, we propose that people’s responses to resource scarcity depend on the harshness of their early-life environment, as reflected by ch...
متن کاملPrenatal influences on reproductive life history strategies.
Over the past two decades, evolutionary and behavioural ecologists have become increasingly interested in the adaptive consequences of intraspecific variability in life history and behavioural strategies. Recently, behavioural endocrinologists have begun to uncover surprising relationships between levels of prenatal exposure to gonadal hormones and variation in reproductive behaviour in adultho...
متن کاملImplications of life-history strategies for obesity.
The association between low socioeconomic status (SES) and obesity is well documented. In the current research, a life history theory (LHT) framework provided an explanation for this association. Derived from evolutionary behavioral science, LHT emphasizes how variability in exposure to unpredictability during childhood gives rise to individual differences in a range of social psychological pro...
متن کاملAltered life - history strategies protect malaria parasites against drugs
11 Drug resistance has been reported against all antimalarial drugs, and while parasites can evolve 12 classical resistance mechanisms (e.g., efflux pumps), it is also possible that changes in life 13 history traits could help parasites evade the effects of treatment. The life history of malaria 14 parasites is governed by an intrinsic resource allocation problem: specialized stages are require...
