Niche models are a notable class of CRMs which are described by the system of coupled ordinary differential equations, [7] [8] = (), =, …,, = + = (), =, …,, where (, …,) is a vector abbreviation for resource abundances, is the per-capita growth rate of species , is the growth rate of species in the absence of consumption, and is the rate per unit species population that species depletes ...
Consumer–resource interactions are the core motif of ecological food chains or food webs, [1] and are an umbrella term for a variety of more specialized types of biological species interactions including prey-predator (see predation), host-parasite (see parasitism), plant-herbivore and victim-exploiter systems.

Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods excluding the amniotes (tetrapods with an amniotic membrane , such as modern reptiles , birds and mammals ).

As a result, the AArk and its partners created a resource called the Amphibian Conservation Needs Assessment, which is used to prioritize conservation efforts for different species and determine what methods are appropriate for conserving the species.
