Abstract: | Considerable sums of money are aimed at biodiversity conservation programs at present, and although collection of specimens
is necessary for the advancement of taxonomy and systematics, we detected a dilemma between conservation and collection of
rare species with small populations. Collecting may act synergistically with other factors to increase the risk of, or even
drive species to extinction. We present some examples we believe show the conflict between collecting rare species with a
small population and the conservation programs for those species. We also stress the need to review the Minimum Viable Population
Size concept as it can be used as a justification for collecting small, rare, and declining population species. |
