“…Consequently, we do not recognize that the unprotected matrix may serve as source or destination locations for species undergoing climate-induced range shifts in and out of protected areas, respectively. Although this could be an important consideration in regions with fairly low land use intensities (e.g., Balogun et al, 2022), this is not always the case when protected areas are concentrated in particular landforms (e.g., mountains; Figure 6). Ultimately, future studies could better incorporate the unprotected matrix by, for example, including lands with low land-use intensities (cf.…”

Species across the planet are shifting their ranges to track suitable climate conditions in response to climate change. Given that protected areas have higher quality habitat and often harbor higher levels of biodiversity compared to unprotected lands, it is often assumed that protected areas can serve as steppingstones for species undergoing climate‐induced range shifts. However, there are several factors that may impede successful range shifts among protected areas, including the distance that must be traveled, unfavorable human land uses and climate conditions along potential movement routes, and lack of analogous climates. Through a species‐agnostic lens, we evaluate these factors across the global terrestrial protected area network as measures of climate connectivity, which is defined as the ability of a landscape to facilitate or impede climate‐induced movement. We found that over half of protected land area and two‐thirds of the number of protected units across the globe are at risk of climate connectivity failure, casting doubt on whether many species can successfully undergo climate‐induced range shifts among protected areas. Consequently, protected areas are unlikely to serve as steppingstones for a large number of species under a warming climate. As species disappear from protected areas without commensurate immigration of species suited to the emerging climate (due to climate connectivity failure), many protected areas may be left with a depauperate suite of species under climate change. Our findings are highly relevant given recent pledges to conserve 30% of the planet by 2030 (30 × 30), underscore the need for innovative land management strategies that allow for species range shifts, and suggest that assisted colonization may be necessary to promote species that are adapted to the emerging climate.

“…In Serbia, one of the main hotspots of hoverfly (Syrphidae) diversity in Europe, PAs are only partly efficient in the conservation of this family of pollinating insects [40]. A recent study [41] assessing insect pollinator diversity in protected vs. unprotected areas in a hotspot of biodiversity in Nigeria found that pollinator diversity varied more in relation to land-use type rather than area protection per se.…”

Understanding the contribution of protected areas to pollinating insect conservation is crucial, especially in Haiti because of intense deforestation and environmental degradation. We compared pollinating insect assemblage composition and abundance in two protected areas: the suburban Wynne Farm Ecological Reserve (WFER) and the Urban National Park of Martissant (UNPM). Both sites encompass forest patches, agroforestry, and agricultural crops. Using colored pan-traps, we collected 3722 insects from six Orders, with 68.2% identified to family level due to taxonomic limitations. WFER exhibited significantly higher insect abundance than UNPM, though habitat differences varied between sites. Site, habitat, and their interaction significantly influenced insect composition. Among 118 identified families, only 30.51% were shared between sites. Our data suggest combined protection offers broader and more even insect diversity. We discovered patrimonial lepidopteran and hymenopteran species previously unrecorded in Haiti, emphasizing the importance of protected areas and the need for enhanced entomological expertise.

Introduction: Significant risks to the health of humans and ecosystems are posed by environmental pollution, urban warming, and fragmentation, which are primary urban factors that contribute to the deterioration of urban ecosystems. The purpose of this multidisciplinary study is to compare greenspaces in university campuses and the host cities in order to assess how valuable they are for promoting human and ecosystem health in Nigeria. Methods: Mixed-methods research that will be conducted in five tertiary institutions and their host cities in southwestern Nigeria. Based on the objectives, the study is divided into four work packages (WP). WP 1 will use suitable sampling traps and scheduled field observations to quantify the diversity of plants and pollinators. Quantitative evaluation of well-being and mental health will be done in WP 2. In WP 3, the relationship between ecosystem health and mental health will be examined and in-depth interviews will be used to explore the socioecological perceptions and interaction of people with specific indicators of ecosystem health in greenspace. In WP 4, a nature-based intervention will be developed and evaluated in a pilot study to determine its feasibility and acceptability. Results: The 2023 TETFund National Research Fund Intervention provided funding for this work, which is currently ongoing. Conclusion: This project will provide scientific knowledge to support evidence-based policy for relevant stakeholders and regulatory organisations, with the goal of promoting greenspace infrastructure in Nigerian tertiary institutions.
