[CBNPMP-Thématique] Conservation et gestion des espècesRésumé : Translocations are being increasingly proposed as a way of conserving biodiversity, particularly in the management of threatened and keystone species, with the aims of maintaining biodiversity and ecosystem function under the combined pressures of habitat fragmentation and climate change. Evolutionary genetic considerations should be an important part of translocation strategies, but there is often confusion about concepts and goals. Here, we provide a classification of translocations based on specific genetic goals for both threatened species and ecological restoration, separating targets based on ‘genetic rescue’ of current population fitness from those focused on maintaining adaptive potential. We then provide a framework for assessing the genetic benefits and risks associated with translocations and provide guidelines for managers focused on conserving biodiversity and evolutionary processes. Case studies are developed to illustrate the framework. Lien pérenne : DOI : 10.1111/j.1752-4571.2011.00192.x Permalink : https://biblio.cbnpmp.fr/index.php?lvl=notice_display&id=149230

[CBNPMP-Thématique] Restauration des écosystèmesRésumé : There is increasing awareness that the long-term success of ecological restoration efforts can be compromised if projected climate change is not effectively incorporated in restoration planning. We propose an approach that aims to support the decision-making process for seed provenance selection in ecological restoration when clear genetic-based guidelines for seed transfer are not available. The approach takes advantage of the increasing availability and refinement of user-friendly web-based GIS interfaces that allow non-experts to directly access biodiversity and environmental data, and build species distribution models. It offers an easily accessible desktop method that land managers and practitioners can use to gain insight: (1) on the overall spatial implications of projected climate change to their restoration project; (2) whether assisted gene flow through climate-adjusted provenance may be appropriate for a given species at a given restoration site; and (3) how far away and in which direction from the restoration site seeds should be collected from. This approach should be used in the early stages of the restoration project to help frame the decision-making process in a climate change context, and can also be used as a platform where other lines of evidence are integrated. We advocate that, in the context of rapid climate change, the climate-adjusted provenance is a promising approach to seed sourcing in ecological restoration, and we suggest its refinement in a way that hedges against uncertainty in climatic projections.

Titre : Phylogenetics and the conservation and utilisation of Acacia in Western Australia Type de document : Imprimé Auteurs : Margaret Byrne Année de publication : 2002 Article en page(s) : 10-18 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Revégétalisation Résumé : The genus Acacia is a dominant component of the Australian flora and many species have been identified as requiring conservation management, and as having potential for utilisation for a wide range of purposes. Phylogenetics is particularly valuable in the south-west of Western Australia where the complex evolutionary history has resulted in a diverse flora with both relictual and recently evolved components. Phylogenetic analysis contributes to conservation of plants through identification of unique evolutionary lineages, determination of phylogenetic value for conservation priority setting, and identifying phylogenetically independent comparisons between rare and widespread species. Phylogenetic analysis also contributes to utilisation of plants through the identification of genetic and taxonomic units, particularly for species complexes where variation is unresolved. The contribution of phylogenetic analysis to these aspects of effective conservation management and efficient utilisation strategies are discussed with examples from various Acacia species in Western Australia Permalink : https://biblio.cbnpmp.fr/index.php?lvl=notice_display&id=148718
