Määritelmä: A taxon is Extinct when there is no reasonable doubt that the last individual has died. A \r\ntaxon is presumed Extinct when exhaustive surveys in known and/or expected habitat, \r\nat appropriate times (diurnal, seasonal, annual), throughout its historic range have failed \r\nto record an individual. Surveys should be over a time frame appropriate to the taxon’s life cycle and life form.
Määritelmä: A heterotroph with a temporary parasitic association with another organism that leads to the death of the host. After which, the parasitoid can continue without the host or can move on to a new host. These organisms are considered partly parasites and partly predators.
