Species distribution modelling (SDM), also known as environmental (or ecological) niche modelling (ENM), habitat modelling, predictive habitat distribution modelling, and range mapping [1] uses ecological models to predict the distribution of a species across geographic space and time using environmental data. The environmental data are most ...
Ecological niche. The flightless dung beetle occupies an ecological niche: exploiting animal droppings as a food source. In ecology, a niche is the match of a species to a specific environmental condition. [1][2] It describes how an organism or population responds to the distribution of resources and competitors (for example, by growing when ...
Mechanistic models of niche apportionment are intended to describe communities. Researchers have used these models in many ways to investigate the temporal and geographic trends in species abundance. For many years the fit of niche apportionment models was conducted by eye and graphs of the models were compared with empirical data. [5]
e. Advanced Placement (AP) Environmental Science (also known as APES, AP Enviro, AP Environmental, AP Environment, or AP EnviroSci) is a course and exam offered by the American College Board as part of the Advanced Placement Program to high school students interested in the environmental and natural sciences. AP Environmental Science was first ...
Definition. An ecotype is a variant in which the phenotypic differences are too few or too subtle to warrant being classified as a subspecies. These different variants can occur in the same geographic region where distinct habitats such as meadow, forest, swamp, and sand dunes provide ecological niches. Where similar ecological conditions occur ...
Niche construction theory (NCT) has been anticipated by diverse people in the past, including by the physicist Erwin Schrödinger in his What Is Life? and Mind and Matter essays (1944). An early advocate of the niche construction perspective in biology was the developmental biologist, Conrad Waddington. He drew his attention to the many ways in ...
Ecological forecasting uses knowledge of physics, ecology and physiology to predict how ecological populations, communities, or ecosystems will change in the future in response to environmental factors such as climate change. The goal of the approach is to provide natural resource managers with information to anticipate and respond to short and ...
Ecosystem ecology is an inherently interdisciplinary field of study. An individual ecosystem is composed of populations of organisms, interacting within communities, and contributing to the cycling of nutrients and the flow of energy. The ecosystem is the principal unit of study in ecosystem ecology. Population, community, and physiological ...
