Abstract 1. Climate change is already having profound effects on biodiversity, but climate adaptation has yet to be fully incorporated into area-based management tools used conserve such as protected areas. One main obstacle its inclusion the lack of consensus regarding how impacts can included in spatial conservation plans.2. We propose a climate-smart framework that prioritizes protection refugia—areas low exposure and high biodiversity retention—identified using metrics. explore four aspects planning proposed framework: i) model ensembles; ii) multiple emission scenarios; iii) metrics; iv) approaches identifying refugia. illustrate this Western Pacific Ocean, it equally applicable terrestrial systems.3. All considered affected configuration plans. The choice metrics refugia result large differences plans, whereas models scenarios have smaller effects. As plans depended used, plan based single measure (e.g., warming) will not necessarily robust against other measures ocean acidification). recommend including most relevant for considered. To include uncertainty associated with different futures, we (i.e., an ensemble) scenarios. Finally, show identify come trade-offs between degree which they are their efficiency meeting targets. Hence, approach depend relative value stakeholders place adaptation.4. By framework, areas designed improved longevity thus safeguard current future change. hope helps transition towards approaches.

Global coral reef ecosystems face various levels of disturbance pressure. Understanding the depth-structured variation in fish communities can help us to better grasp and predict adaptive changes ecosystem under different stressors. This study applied eDNA metabarcoding technology analyze spatial distribution at depths (0 m, 5 10 15 20 30 40 50 60 m) within Xisha Islands China. The results indicated that detected a total 213 amplicon sequence variants (ASVs), including 33 species were not identified using traditional methods. Herbivorous generally dominated relative abundance across depths. Moreover, similarity among depth groups was largely absent, significant differences existed assemblages gradients, consistent with unique preferences microhabitats. Importantly, our findings revealed distinct functional fish. Large carnivorous initially increased then decreased along gradient from 0 turning point around while large herbivorous displayed opposite trend. Small small consistently declined same gradient. Additionally, Margalef index (D) Function richness (FRic) both downward trend increasing depth, Shannon–Wiener (H′), Pielou (J′), Quadratic entropy (RaoQ), Functional dispersion (FDis), evenness (FEve) decreased, peaking m. is an effective tool for evaluating biodiversity, community composition, distribution. It enhances understanding dynamics offers valuable insights conservation restoration efforts.

Abstract Anticipating and mitigating the impacts of climate change on biodiversity requires a comprehensive understanding key habitats utilized by species. Yet, such information for high mobile marine megafauna species remains limited. Here, we compile global database comprising published satellite tracking data (n = 1035 individuals) to spatially delineate foraging grounds seven sea turtle assess their thermal stability. We identified 133 areas distributed around globe, which only 2% total surface is enclosed within an existing protected area. One-third coverage hotspots situated in seas, where conservation focus often neglected. Our analyses revealed that more than two-thirds these vital will experience new temperature (SST) conditions 2100, exposing turtles potential risks. findings underline importance ocean efforts, can meet challenges even remote environments.
