The effects of Pleistocene glaciations on the genetic characteristics of the most austral conifer in the world, Pilgerodendron uviferum, were analysed with specific reference to the hypothesis that the species persisted locally in ice-free areas in temperate South America.
Results indicated that Pilgerodendron populations are highly monomorphic, probably reflecting past population bottlenecks and reduced gene flow. Southernmost populations tend to be the least genetically variable and were therefore probably more affected by glacial activity than northern ones. Populations located outside ice limits seem to have been isolated during the glacial period. The presence of centres of genetic diversity, together with the lack of a significant correlation between genetic and geographical distances and the absence of geographical patterns of allelic frequencies at most analysed alleles, may indicate that Pilgerodendron did not advance southward after the last glaciation from a unique northern refugium, but spread from several surviving populations in ice-free areas in Patagonia instead.Resource Type: Journal Papers
Recent CITES decisions that accepted an obligation to take into account the impacts of CITES listings on the livelihoods of the poor, have some affinities with the ‘Do no harm’ approach to the livelihoods of the poor. The process will produce guidelines and rapid assessment tools. If these guidelines and tools are to be effective they will need to take account of the context-specific nature of solutions in this area. The CITES case provides lessons for other international conservation institutions whose activities affect the livelihoods of the poor at the local level.Resource Type: Journal Papers
UNEP-WCMC produces regular outputs of net trade in wild-collected fauna and flora listed on CITES Appendix II as part of the CITES Review of Significant Trade process.
UNEP-WCMC also produced Reviews of Significant Trade for the species selected for review following CoP14 for recent Animals and Plants Committee meetings (including AC25, PC19 and AC26).Resource Type: Reports
The Checklist of CITES Species provides the official list of CITES-listed species (scientific names) and their associated scientific synonyms; common names in English, French and Spanish (where available) and the CITES Appendix in which they are currently listed. Information on historical Appendix listings, reservations and level of listing (e.g. if a whole family or order is listed) is also available through this website.
