Abstract: | Programs for monitoring biological diversity over time are needed to detect changes that can constitute threats to biological
resources. The convention on biological diversity regards effective monitoring as necessary to halt the ongoing erosion of
biological variation, and such programs at the ecosystem and species levels are enforced in several countries. However, at
the level of genetic biodiversity, little has been accomplished, and monitoring programs need to be developed. We define “conservation
genetic monitoring” to imply the systematic, temporal study of genetic variation within particular species/populations with
the aim to detect changes that indicate compromise or loss of such diversity. We also (i) identify basic starting points for
conservation genetic monitoring, (ii) review the availability of such information using Sweden as an example, (iii) suggest
categories of species for pilot monitoring programs, and (iv) identify some scientific and logistic issues that need to be
addressed in the context of conservation genetic monitoring. We suggest that such programs are particularly warranted for
species subject to large scale enhancement and harvest—operations that are known to potentially alter the genetic composition
and reduce the variability of populations. |
