Titre : Seguiment de l’endemisme dels Pirineus orientals Delphinium montanum per la xarxa transfronterera FloraCat Type de document : Extrait d'ouvrage Auteurs : Pere Aymerich, Auteur ; Xavier Olivier Martinez-Fornés, Auteur ; Sandra Mendez, Auteur ; Alain Mangeot, Auteur ; Maria P. Martin, Auteur ; Beatriu Tenas, Auteur Année de publication : 2020 Langues : Français (fre) Catégories : [CBNPMP-Thèmes] Endémisme Mots-clés : Delphinium montanum DC. Résumé : The FloraCat network is a cross-border collaborative project for the study and monitoring of the rare and endangered flora of the Eastern Pyrenees, active since 2012. Currently all the populations of Delphinium montanum, a rare endemic plant of the Eastern Pyrenees, are monitored by the FloraCat network. The update of the information on this species shows that it is present in 8 sectors, with a minimum of 18 locations, and that it has an estimated global population of 7,800-10,300 breeding plants. This population is concentrated in the Serra del Cadí range (65-70% of the total) and in the Puigmal massif (25-30%). Local populations show different typologies, which are apparently related to the characteristics of the habitats, especially with the availability of more or less favorable micro-habitats for germination and growth of plants in their first years. The depredation of herbivorous mammals (especially Pyrenean chamois) is high in most populations and mainly affects inflorescences, but there is not evidence that it affects significantly the germination or the recruitment. Knowledge of population dynamics is still insufficient, but it seems that there is long-term stability in the large-sized populations, while some of the medium-sized have experienced strong recent regressions. There are data that suggest that smaller populations may come from modern colonization or, alternatively, from the recovery of populations temporarily disappeared by the germination of persistent seeds in the soil. With the available data, this species is classified as NT on a global scale according to IUCN standard criteria.

Richard Ranunculus lateriflorus Résumé : mall demographic size and reduced genetic diversity increase the extinction probability of a population. Genetic diversity within populations for neutral markers is an heuristic parameter, as it reflects past and ongoing processes acting on populations, and informs on possible futures. This study presents a synthesis of the knowledge on neutral genetic diversity for threatened plants in metropolitan France and the use of such data in management actions. Pairing threatened species with the closest non-threatened species for which we could find appropriate genetic data, we collected information on genetic diversity for 25 threatened species and non-threatened controls. We found that threatened species in France have on average a lower within-population genetic diversity than non-threatened controls and thus are exposed to risks linked to genetic erosion. Combining an analysis of recovery plans and a survey addressed to practitioners, we concluded that genetic diversity is rarely integrated in management actions. The integration of such information into applied conservation remains a challenge. We provide some guidelines to collect biological traits impacting within-population genetic diversity and some specific recommendations for a better incorporation of population genetics concepts into conservations actions.
