RESUMEN

Genetic monitoring of populations currently attracts interest in the context of the Convention on Biological Diversity but needs long-term planning and investments. However, genetic diversity has been largely neglected in biodiversity monitoring, and when addressed, it is treated separately, detached from other conservation issues, such as habitat alteration due to climate change. We report an accounting of efforts to monitor population genetic diversity in Europe (genetic monitoring effort, GME), the evaluation of which can help guide future capacity building and collaboration towards areas most in need of expanded monitoring. Overlaying GME with areas where the ranges of selected species of conservation interest approach current and future climate niche limits helps identify whether GME coincides with anticipated climate change effects on biodiversity. Our analysis suggests that country area, financial resources and conservation policy influence GME, high values of which only partially match species' joint patterns of limits to suitable climatic conditions. Populations at trailing climatic niche margins probably hold genetic diversity that is important for adaptation to changing climate. Our results illuminate the need in Europe for expanded investment in genetic monitoring across climate gradients occupied by focal species, a need arguably greatest in southeastern European countries. This need could be met in part by expanding the European Union's Birds and Habitats Directives to fully address the conservation and monitoring of genetic diversity.

RESUMEN

Genetic diversity among and within populations of all species is necessary for people and nature to survive and thrive in a changing world. Over the past three years, commitments for conserving genetic diversity have become more ambitious and specific under the Convention on Biological Diversity's (CBD) draft post-2020 global biodiversity framework (GBF). This Perspective article comments on how goals and targets of the GBF have evolved, the improvements that are still needed, lessons learned from this process, and connections between goals and targets and the actions and reporting that will be needed to maintain, protect, manage and monitor genetic diversity. It is possible and necessary that the GBF strives to maintain genetic diversity within and among populations of all species, to restore genetic connectivity, and to develop national genetic conservation strategies, and to report on these using proposed, feasible indicators.

RESUMEN

Global conservation policy and action have largely neglected protecting and monitoring genetic diversity-one of the three main pillars of biodiversity. Genetic diversity (diversity within species) underlies species' adaptation and survival, ecosystem resilience, and societal innovation. The low priority given to genetic diversity has largely been due to knowledge gaps in key areas, including the importance of genetic diversity and the trends in genetic diversity change; the perceived high expense and low availability and the scattered nature of genetic data; and complicated concepts and information that are inaccessible to policymakers. However, numerous recent advances in knowledge, technology, databases, practice, and capacity have now set the stage for better integration of genetic diversity in policy instruments and conservation efforts. We review these developments and explore how they can support improved consideration of genetic diversity in global conservation policy commitments and enable countries to monitor, report on, and take action to maintain or restore genetic diversity.

RESUMEN

BACKGROUND: Ethnographic research can help to establish dialog between conservationists and local people in reintroduction areas. Considering that predator reintroductions may cause local resistance, we assessed attitudes of different key actor profiles to the return of the Iberian lynx (Lynx pardinus) to Portugal before reintroduction started in 2015. We aimed to characterize a social context from an ethnoecological perspective, including factors such as local knowledge, perceptions, emotions, and opinions. METHODS: We conducted semi-structured interviews (n = 131) in three different protected areas and observed practices and public meetings in order to describe reintroduction contestation, emotional involvement with the species, and local perceptions about conservation. Detailed content data analysis was undertaken and an open-ended codification of citations was performed with the support of ATLAS.ti. Besides the qualitative analyses, we further explored statistic associations between knowledge and opinions and compared different geographical areas and hunters with non-hunters among key actors. RESULTS: Local ecological knowledge encompassed the lynx but was not shared by the whole community. Both similarities and differences between local and scientific knowledge about the lynx were found. The discrepancies with scientific findings were not necessarily a predictor of negative attitudes towards reintroduction. Contestation issues around reintroduction differ between geographical areas but did not hinder an emotional attachment to the species and its identification as a territory emblem. Among local voices, financial compensation was significantly associated to hunters and nature tourism was cited the most frequent advantage of lynx presence. Materialistic discourses existed in parallel with non-economic factors and the existence of moral agreement with its protection. The considerable criticism and reference to restrictions by local actors concerning protected areas and conservation projects indicated the experience of an imposed model of nature conservation. Opinions about participation in the reintroduction process highlighted the need for a closer dialog between all actors and administration. CONCLUSIONS: Local voices analyzed through an ethnoecological perspective provide several views on reintroduction and nature conservation. They follow two main global trends of environmental discourse: (1) nature becomes a commodified object to exploit while contestation about wildlife is centered on financial return and (2) emblematic wild species create an emotional attachment, become symbolic, and gather moral agreement for nature protection. Lynx reintroduction has been not only just a nature protection theme but also a negotiation process with administration. Western rural communities are not the "noble savages" and nature protectors as are other traditional groups, and actors tend to claim for benefits in a situation of reintroduction. Both parties comprehend a similar version of appropriated nature. Understanding complexity and diverse interests in local communities are useful in not oversimplifying local positions towards predator conservation. We recommend that professional conservation teams rethink their image among local populations and increase proximity with different types of key actors.
