CG: Taxonomy is the essential background information on which to base conservation decisions. The<br />
species should remain the main unit, compared to the subspecies.<br />
IN: I agree with CG; species should be the conservation unit, but the subspecies should also be<br />
considered.<br />
CH: The priority is to concentrate on the taxonomy of wild remnant populations, not on captive<br />
animals of doubtful origin.<br />
AG: The best way to solve taxonomic questions is to prioritize in situ conservation, and conserve the<br />
local existing populations, when feasible.<br />
DW: Taxonomy may also enable captive populations to make valuable contribution to conservation.<br />
EH: Taxonomy should allow us to define conservation units from which breeding will give fertile<br />
offspring.<br />
AG: These conservation units could also represent groups of animals that are reproducing without<br />
showing any inbreeding or outbreeding depression in the long-term.<br />
DW: Some important conservation issues are not addressed by taxonomy, e.g. adaptation to the<br />
environment. It is also important to consider the distribution, the ecology and the behavior of the<br />
concerned taxon.<br />
GS: Taxonomy must first give indications of local adaptations. Morphology and thus taxonomy<br />
reflect adaptation to a local environment.<br />
MAZ: The problem is not only to answer why taxonomic questions should be raised in conservation<br />
but also when.<br />
AG: This question should be raised during the early stages of any conservation project.<br />
- AG: What is the conservation interest of subspecies<br />
DW: Many subspecies are really ecotypes (like the wild boar Sus scrofa in North Africa). But<br />
subspecies are often incorrectly identified.<br />
IN: Subspecies must represent populations, not type specimens. Their description should be based on<br />
several aspects (e.g. morphology, genetics, physiology, behaviour, ...).<br />
GS: Subspecies give indications of the geographical variability within a species.<br />
AG: Subspecies also represent the evolutionary potential of new species.<br />
TS: The species level is sometimes too restrictive. Certain conservation projects are directed to the<br />
subspecific level.<br />
CG, GS, MAZ: A non-local subspecies should be reintroduced only if the local subspecies is<br />
completely extinct, as is the case for the ostrich (Struthio came/us ) and the wild ass (Equus<br />
hemionus) in Saudi Arabia.<br />
EH: The subspecies should be based on good genetic and biochemical evidence, aesthetic criteria and<br />
behavioral adaptations.<br />
SK: Taxonomists must support conservation by providing the most complete taxonomic information<br />
available.<br />
