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.
Collagen is an important protein that helps build the tissues of humans and animals. It is very strong because it is made of three protein strands twisted tightly together like a rope. Because of this sturdy structure, ordinary ...

Accents are usually thought of as a human trait, indicating where a person has grown up or the communities they belong—and new research shows the same dialects can also occur in Australia's largest carnivorous bat.

For decades, scientists have observed a clear pattern across the natural world: biodiversity tends to be higher near the equator and lower toward the poles. Known as the latitudinal diversity gradient (LDG), this trend holds ...

Three-hundred-million years ago, Earth was very different. The continents had coalesced into Pangea, which was dominated in its equatorial regions by vast coal-swamp forests. With high atmospheric oxygen levels, wildfires ...
