homozygosity and allelic richness (genetic parameters). Indirect metrics may include measures of population change of the Koala inferred from changes in habitat area or a categorical measure such as an overall condition score for Koala health.
Landscape effects. The consequences of ecologically threatening processes acting on Koala habitat and landscapes. Examples include habitat loss and fragmentation, changes in habitat quality.
Listed Koala. The legal entity covered by this recovery plan, being Phascolarctos cinereus (combined populations of Queensland, New South Wales and the Australian Capital Territory) which is listed as Endangered under the EPBC Act. This entity is considered to be a 'species' for the purposes of the EPBC Act. See also see Species (legal definition), in this glossary.
Metapopulation (synonyms: composite population, assemblage of populations). The set of biological populations within a larger area, where movement or gene flow from one biological population to at least some other patches is possible and is important for maintaining abundance and distribution at regional scale, even if such movement is infrequent.
Metapopulation processes. The processes acting on populations that influence spatial structure of populations. Processes that cause extinction and recolonisation and affect metapopulation structure may be caused by disruption to dispersal patterns and exchange of genes between populations, changes in the carrying capacity of habitat and therefore the size of populations and their viability, changes to sex ratios, and mortality rates.
Model. A physical or mathematical or conceptual representation of ideas, events or processes.
Patch. Location or area of habitat with all the necessary resources for the persistence of a population and that is separated from other patches by inhospitable habitat that does not contain all the resources necessary for long-term survival and reproduction (though the inhospitable habitat may allow movement). At any given time, a patch may be occupied or empty. Isolated patches are those patches separated from other patches by habitat or a distance that is unlikely to be traversed by Koalas.
Population (biological definition). A biological population as defined in this recovery plan is a set of individuals that live in the same habitat patch and interact with one another, commonly forming a breeding unit within which the exchange of genetic material is more or less unrestricted (synonyms: local population, subpopulation, deme).
Population effects. The consequences of ecologically threatening processes acting on Koala populations and individuals that influence the demographic structure and status of populations. Examples include stress, changes to mortality rates and recruitment.
Species (legal definition). Following the EPBC Act (s528) a species is a group of biological entities that (a) interbreed to produce fertile offspring; or (b) possess common characteristics derived from a common gene pool; and includes (c) a sub-species.
