Legacies in life histories.
Complex life-histories are common in nature, have many important biological consequences, and are an important focal area for integrative biology. For organisms with complex life-histories, a legacy is something handed down from an ancestor or previous stage, and can be genetic, nutritional/provisional, experiential, as well as the result of random chance and natural variation in the environmen...
متن کاملLife histories of pathogen populations.
The populations of pathogens in individual hosts have many of the characteristics of multicellular organisms, or individuals. These populations go through a life cycle within a host and they reproduce by founding daughter populations in new hosts. Natural selection shapes the life history characteristics of pathogen populations--life expectancy, trade-offs in the allocation of resources between...
متن کاملMacroparasite Life Histories
Parasites and parasitism is common. Worm macroparasites have evolved life-history traits that allow them to successfully transmit between spatially and temporally separated patches of host resource and to survive within these environments. Macroparasites have common life-history strategies to achieve this, but these general themes are modified in a myriad of ways related to the specific biology...
متن کاملEvolution of mammal life histories
If we assume that adult life span and age-at-maturity are described correctly by quarter power allometries across (typical) mammal species, we are tempted to look for some fundamental explanation. The explanation must acknowledge that within-species growth is sigmoid and not a power function at all, and that natural selection probably sets the age at maturity in the face of externally imposed m...
متن کاملLife Histories and Mental Health
A life history approach to understanding four diverse mental health outcomes is presented. The central aim is to begin with richly detailed, “thick” descriptions of individuals’ lives and from them, to discern generalizable features to account for targeted outcomes. Conceptual principles guiding the organization and interpretation of life history information are summarized. Data from the Wiscon...
