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.
Every ecosystem is shaped by billions of invisible battles: organisms competing for light, nutrients, space, or mates. These competitive interactions determine which species survive, how they evolve, and how vibrant and resilient ...

Microbes often display cooperative behavior in which individual cells put in work and sacrifice resources to collectively benefit the group. But sometimes, "cheater" cells in the group may reap the benefits of this cooperation ...

Two new studies into lizard colors reveal how one species maintains its colorful diversity while others are losing their ancient colors. And the changes are being driven by the biological equivalent of rock-paper-scissors.
Scientists reveal that the scale of analysis determines whether invasive plants succeed by resembling or differing from native species, resolving decades of conflicting ecological evidence.
