Pathways towards a sustainable future envisioned by early-career conservation researchers

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

Biological protection against grape berry moths. A review

Grape is a major crop, covering 7.5 M ha worldwide, that is currently being confronted with three main challenges: intensive pesticide use that must be reduced, invasion by new pests/diseases, and climate change. The biological control of pests and vectors would help address these challenges. Here, we review the scientific literature on the biological control of grape moths by macroorganisms (excluding nematodes). Two components, biological control with an active human role, mainly using biocontrol agents through inundation or inoculation, and conservation biological control, are considered. The major points are the following. (1) Tortricid grape moths seriously damage grapes worldwide, causing yield losses and quality reduction. The more geographically widespread species, Lobesia botrana, continues to extend its range, invading South American and, more recently, North American vineyards. (2) Parasitoids and predators (including arthropods, birds, and bats) that can control grape pests are very diverse. (3) Different methods exist to assess pest control efficiency in the field but some of them remain to be developed. (4) Environmental factors, including host plants, landscape, grass or floral covers, and organic practices, affect the natural control of grape moths. (5) Pest resistance to parasitoids strongly depends on their immune system, which is controlled by the host plant. Future climate changes may modify this tritrophic interaction and thus affect biological control strategies. We conclude that biological control has a great deal of potential in viticulture and that addressing these key factors would improve the efficiency levels of biological control strategies. This would help growers and stakeholders to significantly reduce insecticide use in vineyards
