Scientists have warned decision-makers about the severe consequences of the global environmental crisis since the 1970s. Yet ecological degradation continues and little has been done to address climate change. We investigated early-career conservation researchers' (ECR) perspectives on, and prioritization of, actions furthering sustainability. We conducted a survey (n = 67) and an interactive workshop (n = 35) for ECR attendees of the 5th European Congress of Conservation Biology (2018). Building on these data and discussions, we identified ongoing and forthcoming advances in conservation science. These include increased transdisciplinarity, science communication, advocacy in conservation, and adoption of a transformation-oriented social–ecological systems approach to research. The respondents and participants had diverse perspectives on how to achieve sustainability. Reformist actions were emphasized as paving the way for more radical changes in the economic system and societal values linked to the environment and inequality. Our findings suggest that achieving sustainability requires a strategy that (1) incorporates the multiplicity of people's views, (2) places a greater value on nature, and (3) encourages systemic transformation across political, social, educational, and economic realms on multiple levels. We introduce a framework for ECRs to inspire their research and practice within conservation science to achieve real change in protecting biological diversity.

International audience; The taxonomic status of the gerbil Gerbillus amoenus in relation to Gerbillus nanus and the distribution range of these two species in Africa and/or Asia have long been debated and are not yet fully clarified. In our study, we identify two specimens of small gerbils that we captured in two localities of the south of Morocco, using morphometric and/or molecular tools. The body and skull measurements were not able to unambiguously discriminate between three closely related small gerbils (Gerbillus amoenus, Gerbillus nanus and Gerbillus henleyi). However, the cytochrome b gene analysis showed that our two specimens cluster unambiguously with haplotypes of G. amoenus. This represents the first genetic characterization of G. amoenus in Morocco. It confirms, based on mitochondrial DNA, that the previously described species living in Africa is indeed G. amoenus and not G. nanus, the latter species being present strictly in Asia.

International audience

Gerbillus campestris is a widely distributed small rodent that lives in various habitats in North Africa and can be a potential agricultural pest. We conducted a biogeographic study of this species with an integrative approach using mor-phometric data from body and craniomandibular distances and molecular genetic data from the cytochrome b gene of the mitochondrial DNA. We collected 96 individuals in six localities from central, northern and eastern Morocco. Data from 18 morphological characters were used in multivariate statistical analyses and molecular data were analysed using maxi-mum likelihood and median-joining networks. Our analyses confirmed the high morphological variability in this species and allowed to discriminate four groups containing the studied populations. We found that a few craniomandibular measu-rements had the highest contribution in the differences between populations, and that this variability reflected a spatial and environmental differentiation. In the genetic analyses, we placed our six populations and six individuals from four other countries in nine previously identified phylogenetic lineages in this species, and we also added a tenth lineage. Limited gene flow, isolation by distance and biogeographic barriers were further explored to explain this genetic structuration. We also jointly examined morphometric and genetic variability and found that the morphological groups were congruent with the genetic lineages and the geographic distribution. A better knowledge of the phenotypic plasticity and genetic diversity of this gerbil can be used to comprehend the micro-evolutionary processes in other small mammals in North Africa.
