Environmental change is multidimensional, with local anthropogenic stressors and global climate interacting to differentially impact populations throughout a species' geographic range. Within species, the spatial distribution of phenotypic variation its causes (i.e., adaptation or plasticity) will determine adaptive capacity respond changing environment. However, comparatively less known about scale differentiation among how patterns might drive vulnerability stressors. To test whether fine-scale (2-12 km) mosaics environmental stress can cause in marine foundation eelgrass (Zostera marina), we conducted three-way reciprocal transplant experiment spanning length Tomales Bay, CA. Our results revealed strong home-site advantage growth survival for all three populations. In subsequent common garden experiments feeding assays, showed that countergradients temperature, light availability, grazing pressure from an introduced herbivore contribute differential performance consistent adaptation. findings highlight local-scale increase neighboring populations, potentially increasing species resilience future change. More specifically, identified range-center population pre-adapted extremely warm temperatures similar those experienced by low-latitude range-edge eelgrass, demonstrating reservoirs heat-tolerant phenotypes may already exist Future work on predicting should incorporate potential buffering effects promote management approach conservation.

Understanding the cumulative effects of multiple stressors is a research priority in environmental science. Ecological models are key component tackling this challenge because they can simulate interactions between components an ecosystem. Here, we ask, how has popular modeling platform Ecopath with Ecosim (EwE) been used to model human impacts related climate change, land and sea use, pollution, invasive species? We conducted literature review encompassing 166 studies covering other than fishing mostly aquatic ecosystems. The most modeled were physical change (60 studies), species introductions (22), habitat loss (21), eutrophication (20), using range techniques. Despite comprehensive coverage, identified four gaps that must be filled harness potential EwE for studying stressor effects. First, only 12% investigated three or more stressors, focusing on single stressors.

There is growing concern over climate models that project significant changes in the oceans, with consequences on marine biodiversity and human well-being. However, coastal ecosystems respond differently to change-related stressors depending ecosystem, species composition interactions, geomorphologic settings, spatial distribution, but also presence of local interacting cumulatively pressures. Our paper provides a comprehensive review current literature about effects climate-related pressures how affect their resilience. work focuses key from three ecoregions: Caribbean Sea (coral reefs, mangrove forests, seagrass beds), Mediterranean (the coral Cladocora caespitosa, maërl beds beds) North-East Atlantic, which include kelp beds, salt marshes beds.

The United Nations (UN)'s call for a decade of "ecosystem restoration" was prompted by the need to address extensive impact anthropogenic activities on natural ecosystems. Marine ecosystem restoration is increasingly necessary due increasing habitat loss in deep waters (> 200 m depth). At these depths, which are far beyond those accessible divers, only established and emerging robotic platforms such as remotely operated vehicles (ROVs), autonomous underwater (AUVs), landers, crawlers can operate through manipulators their multiparametric sensor technologies (e.g., optoacoustic imaging, omics, environmental probes). use advanced deep-sea provide: ① high-resolution three-dimensional (3D) imaging acoustic mapping substrates key taxa; ② physical manipulation ③ real-time supervision remote operations long-term ecological monitoring; ④ potential work autonomously. Here, we describe how with situ capabilities payloads innovative sensors could autonomously conduct active monitoring across large spatial scales. We expect that devices will be particularly useful habitats, reef-building cold-water corals, soft-bottom bamboo fishery resources have already been damaged offshore industries (i.e., fishing oil/gas).

Coastal ecosystems are increasingly experiencing anthropogenic pressures such as climate warming, CO 2 increase, metal and organic pollution, overfishing, resource extraction. Some resulting stressors more direct like pollution fisheries, others indirect ocean acidification, yet they jointly affect marine biota, communities, entire ecosystems. While single-stressor effects have been widely investigated, the interactive of multiple on less researched. In this study, we review literature their in coastal environments across organisms. We classify interactions into three categories: synergistic, additive, antagonistic. found phytoplankton bivalves to be most studied taxonomic groups. Climate warming is identified dominant stressor which, combination, with other eutrophication, exacerbate adverse physiological traits growth rate, fitness, basal respiration, size. Phytoplankton appears sensitive between nutrient pollution. warm nutrient-enriched environments, presence metals considerably affects uptake nutrients, increases respiration costs toxin production phytoplankton. For bivalves, low pH lethal stressors. The combined effect heat stress acidification leads decreased shell size, acid-base regulation capacity bivalves. However, for a holistic understanding how food webs will evolve ongoing changes, suggest research ecosystem-level responses. This can achieved by combining in-situ observations from controlled (e.g. mesocosm experiments) modelling approaches.
