Landscape fragmentation and farming can affect the diversity of plants and pollinators harbored by linear landscape elements (LLE) in agroecosystems. To assess the role of these habitats in sustaining plant-pollinator communities, twenty portions of LLE (road verges) were studied during two consecutive field seasons in the Argentine Pampas.
Most of the terrestrial world is experiencing high rates of land conversion despite growth of the global protected area (PA) network. There is a need to assess whether the current global protection targets are achievable across all major ecosystem types and to identify those that need urgent protection. Using recent rates of habitat conversion and protection and the latest terrestrial ecoregion map, we show that if the same approach to PA establishment that has been undertaken over the past three decades continues, 558 of 748 ecoregions (ca.
Refuges and refugia are important to conservation management because of their potential to protect species from difficult-to-manage threats such as changing climate, extreme events (e.g., drought, fire) and biotic threats (e.g., disease, invasive species). To provide conservation managers with an evidence-based approach to identifying refuges and refugia, we ask: which places have been observed to function as refuges/refugia, with results reported in the scientific literature? We systematically reviewed the past 20 years of research into refuges/refugia.
Despite global policy commitments to preserve Earth's marine biodiversity, many species are in a state of decline. Using data on 22,885 marine species, we identify 8.5 million km2 of priority areas that complement existing areas of conservation and biodiversity importance. New conservation priorities are found in over half (56%) of all coastal nations, including key priority regions in the northwest Pacific Ocean and Atlantic Ocean.
Evidence-Based Guidelines for Prioritizing Investments to Meet International Conservation Objectives
Biodiversity is in rapid decline, largely driven by habitat loss and degradation. Protected area establishment and management are widely used to maintain habitats and species in perpetuity. Protected area extent has increased rapidly in recent years with area-based targets set within international conservation agreements such as the Convention on Biological Diversity's Aichi Target 11.
Over US$60 trillion is predicted to be spent on new infrastructure globally by 2040. Is it possible to meet UN Sustainable Development Goal (SDG) 9 (develop infrastructure networks) without sacrificing goals 14 and 15 (ending biodiversity loss)? We explore the potential role of “no net loss” (NNL) policies in reconciling these SDGs.

Economic development projects are increasingly applying the mitigation hierarchy to achieve No Net Loss, or even a Net Gain, of biodiversity. Because people value biodiversity and ecosystem services, this can affect the well-being of local people; however, these types of social impacts from development receive limited consideration. We present ethical, practical, and regulatory reasons why development projects applying the mitigation hierarchy should consider related social impacts.
