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.

Clarifying climate change adaptation responses for scattered trees in modified landscapes / Martin F. Breed in Journal of applied ecology, 48 ([01/01/2011]) 

Public Citation [article]  inJournal of applied ecology > 48 [01/01/2011] . - 637-641 Titre : Clarifying climate change adaptation responses for scattered trees in modified landscapes Type de document : Imprimé Auteurs : Martin F. Breed ; Kym M. Ottewell ; Michael G. Gardner ; Andrew J. Lowe Année de publication : 2011 Article en page(s) : 637-641 Langues : Anglais (eng) Catégories : [LOTERRE-Biodiversité] Changement climatique [CBNPMP-Thématique] Conservation et gestion des espèces Résumé : 1. Many studies have investigated adaptation to climate change. However, the term ‘adaptation’ has been used ambiguously and sometimes included parts of both classic evolutionary processes and conservation planning measures (i.e. human-mediated adaptation). 2. To reduce ambiguity, we define three classes of evolutionary processes involved in adaptation – migrational, novel-variant and plasticity. Migrational adaptation describes the process of redistribution of standing genetic variation among populations. Novel-variant adaptation describes the increase in frequency of beneficial, new genetic variants. Plasticity adaptation refers to adaptive plastic responses of organisms to environmental stressors. Quite separately, human-mediated adaptation aims to maintain these evolutionary processes. 3. Whilst the role of scattered trees in migrational adaptation of fauna may have been neglected in the past, their capacity to assist migrational adaptation of trees has been previously documented. However, their role in novel-variant and plasticity adaptation is generally unrecognised, and warrants further attention. 4. Synthesis and applications. By defining different aspects of adaptation carefully, we show that scattered trees should not be cleared since they may facilitate gene flow across fragmented landscapes. However, they should be avoided as dominant seed sources since their stock may be of poor quality.

Priority Actions to Improve Provenance Decision-Making / Martin F. Breed in BioScience, 68 (7) (2018) 

Public Citation [article]  inBioScience > 68 (7) (2018) . - 510-516 Titre : Priority Actions to Improve Provenance Decision-Making Type de document : Imprimé Auteurs : Martin F. Breed ; Peter A.

Lowe ; Pedro Marques ; Paul G. Nevill ; Pati Vitt ; Anna Bucharova Année de publication : 2018 Article en page(s) : 510-516 Langues : Français (fre) Catégories : [CBNPMP-Thématique] Restauration des écosystèmes Résumé : Selecting the geographic origin—the provenance—of seed is a key decision in restoration. The last decade has seen a vigorous debate on whether to use local or nonlocal seed. The use of local seed has been the preferred approach because it is expected to maintain local adaptation and avoid deleterious population effects (e.g., maladaptation and outbreeding depression). However, the impacts of habitat fragmentation and climate change on plant populations have driven the debate on whether the local-is-best standard needs changing. This debate has largely been theoretical in nature, which hampers provenance decision-making. Here, we detail cross-sector priority actions to improve provenance decision-making, including embedding provenance trials into restoration projects; developing dynamic, evidence-based provenance policies; and establishing stronger research–practitioner collaborations to facilitate the adoption of research outcomes. We discuss how to tackle these priority actions in order to help satisfy the restoration sector’s requirement for appropriately provenanced seed.
