Ecological competition is an interaction in which individuals or populations adversely affect each other’s growth, survival, or reproduction by utilizing the same limiting resources within an ecosystem. It is typically classified as intraspecific (within a species) or interspecific (between species) and can be exploitative, where organisms indirectly compete through resource depletion, or interference, involving direct antagonistic behaviors. Competition shapes community structure, species niches, and adaptive trait evolution, and is a central process in population dynamics models such as Lotka–Volterra formulations. Its intensity and outcomes depend on resource availability, environmental heterogeneity, and species-specific functional traits.
Snow leopards, leopards, and Himalayan wolves all share similar stomping grounds in Nepal's Lapchi Valley in the Himalayas. A recent study, published in PLOS One, has taken a closer look at how these apex predators have found ...
Climate-driven disturbances such as marine heat waves are rapidly reducing coral cover and degrading reef ecosystems worldwide. Using a mathematical model, a research team led by Subhendu Chakraborty at the Leibniz Center ...

Many of the most damaging invasions do not simply subtract species; they fundamentally remodel the environment, altering habitats, rewiring interactions, and shifting processes in ways that species lists alone cannot reveal.

An ecosystem is not a still life. Even where everything looks stable—a woodland, a lake, the soil—the internal "bookkeeping" keeps changing: how many individuals belong to which species, and for how long. Some populations ...
