Ecology is a branch of biological and environmental sciences that investigates the distribution, abundance, and dynamics of organisms in relation to each other and to their physical and chemical environments. It encompasses hierarchical levels of organization, including populations, communities, ecosystems, landscapes, and the biosphere. Ecological research examines flows of energy and cycles of matter, species interactions (such as predation, competition, and mutualism), and responses to abiotic factors like climate, nutrients, and disturbance. Quantitative ecological models and empirical studies are used to understand patterns of biodiversity, ecosystem functioning, and the resilience and stability of ecological systems.
With almost a third of cacti species threatened with extinction, a new open-access database of cactus ecology and evolution could help scientists and conservationists save species from the brink.

Intact ecosystems have the capacity for self-regulation, which keeps their complex structure of species—such as animals, plants, fungi and bacteria—in balance. For example, when the population of a species increases, its ...
