Liebig's law has been extended to biological populations (and is commonly used in ecosystem modelling). For example, the growth of an organism such as a plant may be dependent on a number of different factors, such as sunlight or mineral nutrients (e.g., nitrate or phosphate). The availability of these may vary, such that at any given time one ...
As of 2019, over 100 countries had, or were developing, policies for biodiversity offsetting [16] and more than 37 countries required biodiversity offsets by law. [16] These policies generally implement biodiversity offsetting within planning systems to compensate for unavoidable residual damage to biodiversity as the final step of a mitigation ...
The carrying capacity of an environment is the maximum population size of a biological species that can be sustained by that specific environment, given the food, habitat, water, and other resources available. The carrying capacity is defined as the environment 's maximal load, [clarification needed] which in population ecology corresponds to ...
The species–area relationship or species–area curve describes the relationship between the area of a habitat, or of part of a habitat, and the number of species found within that area. Larger areas tend to contain larger numbers of species, and empirically, the relative numbers seem to follow systematic mathematical relationships. [1]
Limnology, paleolimnology, trophic ecology. Institutions. Yale University. Doctoral advisor. Samuel Eddy. Raymond Laurel Lindeman (July 24, 1915 – June 29, 1942) [1][2] was an ecologist whose graduate research is credited with being a seminal study in the field of ecosystem ecology, specifically on the topic of trophic dynamics.
F. Stuart Chapin and co-authors emphasize that ecosystem management is guided by ecological science to ensure the long-term sustainability of ecosystem services, [9] while Norman Christensen and coauthors emphasize that it is motivated by defined goals, employs adaptive practices, and accounts for the complexities of ecological systems.

Ecological footprint. The ecological footprint measures human demand on natural capital, i.e. the quantity of nature it takes to support people and their economies. [ 1 ][ 2 ][ 3 ] It tracks human demand on nature through an ecological accounting system. The accounts contrast the biologically productive area people use to satisfy their ...
Biological rules. The pygmy mammoth is an example of insular dwarfism, a case of Foster's rule, its unusually small body size an adaptation to the limited resources of its island home. A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms.
