Organismal, population, evolutionary and ecological systems is a research area that investigates biological organization and processes from the level of individual organisms to interacting populations and communities, integrating mechanisms of evolution and ecological dynamics. It encompasses studies of organismal physiology, behavior and life histories; population structure, demography and genetics; evolutionary processes such as selection, drift, gene flow and speciation; and ecological interactions including competition, predation, mutualism and ecosystem functioning. This area emphasizes quantitative, often model-based approaches to understanding how traits, genes, environments and interactions shape biodiversity patterns, adaptive change and the stability and resilience of biological systems across spatial and temporal scales.
Non-native wall lizards living in Cincinnati, Ohio, have thrived against the odds thanks to an ability to expand their population more quickly than any inbreeding-amplified harmful genes could weaken their chances for survival, ...
