A change or the process of change by which a living organism or species becomes better suited to its environment.
Adaptive management (AM), aka: Adaptive Resource Management (ARM) or Adaptive Environmental Assessment and Management (AEAM)
A structured, iterative process of robust decision making in the face of uncertainty, with an aim to reducing uncertainty over time via system monitoring. In this way, decision making simultaneously meets one or more resource management objectives and, either passively or actively, accrues information needed to improve future management. Adaptive management is a tool which should be used not only to change a system, but also to learn about the system.

Genetic admixture occurs when two or more previously isolated and genetically differentiated populations begin interbreeding. Admixture results in the introduction of new genetic lineages into a population. It has been known to slow local adaptation by introducing foreign, unadapted genotypes (known as genetic pollution). It also prevents speciation by homogenizing populations and increasing heterozygosity. [Courtesy of]
Adrenocorticotropic hormone (ACTH) is a hormone produced in the anterior, or front, pituitary gland in the brain. The function of ACTH is to regulate levels of the steroid hormone cortisol, which released from the adrenal gland.
Also called “proceptivity.” In the Proestrous stage of breeding wolves, female wolves show behaviors towards a mate in the form of prancing, body rubs and pawing, nuzzling or putting her chin on her mate’s back. As well as presenting her rear to her mate’s nose.
In active submission, the submissive animal approaches another wolf in a low posture, slightly crouched, ears back and close to its head, and tail held low. The submissive wolf wags its tail or hindquarters and attempts to lick or mouth the other wolf’s muzzle. Active submission occurs curs often in “greeting,” during “group ceremonies” in which dominant wolves become the focus of nuzzling, licking, and mouthing about the face by other members of the pack, and as a “nose-push” given by submissive animals toward dominant ones when they are still a few meters away.

A phenomenon in biology characterized by a correlation between population size or density and the mean individual fitness (often measured as per capita population growth rate) of a population or species

Denoting sediment or rock that originated at a distance from its present position.
The term sometimes used to describe the dominant wolves in the social order of the wolf pack. Because a free-ranging wolf pack is a family comprising the parents and their offspring, the term “alphas” has been superseded by “breeding pair” or “breeders” or simply “parents.”
Philosophical viewpoint arguing that human beings are the central or most significant entities in the world. Anthropocentrism regards humans as separate from and superior to nature and holds that human life has intrinsic value while other entities (including animals, plants, mineral resources, and so on) are resources that may justifiably be exploited for the benefit of humankind.
Aristotle (Politics, Bk. 1, Ch. 8) maintains that “nature has made all things specifically for the sake of man” and that the value of non-human things in nature is merely instrumental.
A large scale mode of climate variability, also referred to as the Northern Hemisphere annular mode. The AO is a climate pattern characterized by winds circulating counterclockwise around the Arctic at around 55°N latitude. When the AO is in its positive phase, a ring of strong winds circulating around the North Pole acts to confine colder air across polar regions. This belt of winds becomes weaker and more distorted in the negative phase of the AO, which allows an easier southward penetration of colder, arctic airmasses and increased storminess into the mid-latitudes.

Hatched or born in an undeveloped state and requiring care and feeding by the parents. The word is derived from the Latin root alere, meaning “to nurse, to rear, or to nourish” and indicates the need for young to be fed and taken care of for a long duration.
AZA (American Zoo and Aquarium Association)
[Mexican Gray Wolves]
An association of zoological parks and aquariums in North America that governs over 100 facilities and oversees the governance of the SSP’s and other captive breeding programs.
Annual Growth Rate
Percent growth every year in a population. The annual percentage growth rate is simply the percent growth divided by N, the number of years.

One of the state agencies that participates in the management of the Mexican gray wolf in the recovery area.
A theory in the field of statistics based on the Bayesian interpretation of probability where probability expresses a degree of belief in an event, which can change as new information is gathered, rather than a fixed value based upon frequency or propensity.
An ethical perspective holding that all life deserves equal consideration or has equal moral standing.

Of mammals (BSF) is “a total sum of mammals influence on the environment, changing its structure” (Naumov, 1977).

This includes all of the Apache National Forest and all of the Gila National Forest. This area includes over 4 million acres of mountain,s forests, and grasslands within the historic Mexican wolf range in the U.S.
A payment or other reward for removing or killing certain species of animals designated as harmful. Federal and state governments have used bounties as part of their predator control programs to encourage people to kill wolves.
The term used to refer to the male and the female in the pack who mate and produce offspring.

An area between territories occupied by established wolf packs. Prey species often flourish in buffer zones. Wolves that have dispersed and that are alone often find relative safety and food in buffer zones with less risk of being attacked and killed by members of established packs. However, buffer zones are not necessarily neutral areas and therefore safe havens. These zones may be contested by resident packs.
