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.
Cooperation is a pillar of human society, promoting an exchange of skills and knowledge between different individuals and social groups. Humans typically do not only cooperate with their own family, friends and members of ...
Although the genetic material of most living organisms is DNA, various self-replicating agents rely instead on RNA, including RNA viruses and viroids, which are infectious RNA molecules that are smaller and structurally simpler ...
