Abstract Otolith death assemblages provide a valuable source of biological and ecological information that can help address three main problems in marine conservation: (a) the lack pre-industrial, pre-human-impact baselines for evaluating change; (b) inefficiency survey methods recording small cryptic fish species; (c) absence long-term data on environmental change impacts ecosystems fishes. We review here current knowledge formation preservation otoliths their assemblages, to obtain, date analyse them order detect changes species traits ecology, population structure palaeoceanographic shifts drove them.

Abstract Ocean warming and acidification, decreases in dissolved oxygen concentrations, changes primary production are causing an unprecedented global redistribution of marine life. The identification underlying ecological processes underpinning species turnover, particularly the prevalence increases warm-water or declines cold-water species, has been recently debated context ocean warming. Here, we track mean thermal affinity communities across European seas by calculating Community Temperature Index for 65 biodiversity time series collected over four decades containing 1,817 from different (zooplankton, coastal benthos, pelagic demersal invertebrates fish). We show that most sites have clearly responded to ongoing via abundance (tropicalization, 54%) (deborealization, 18%). Tropicalization dominated Atlantic compared semi-enclosed basins such as Mediterranean Baltic Seas, probably due physical barrier constraints connectivity colonization. Semi-enclosed appeared be vulnerable warming, experiencing fastest rates loss through deborealization.

Abstract Climate change manifestation in the ocean, through warming, oxygen loss, increasing acidification, and changing particulate organic carbon flux (one metric of altered food supply), is projected to affect most deep‐ocean ecosystems concomitantly with direct human disturbance. drivers will alter deep‐sea biodiversity associated ecosystem services, may interact disturbance from resource extraction activities or even climate geoengineering. We suggest that ensure effective management use deep ocean (e.g., for bottom fishing, oil gas extraction, deep‐seabed mining), environmental developing regulations must consider change. Strategic planning, impact assessment monitoring, spatial management, application precautionary approach, full‐cost accounting should embrace consciousness. Coupled biological modeling approaches applied water on seafloor can help accomplish this goal. For example, Earth‐System Model projections climate‐change parameters at reveal heterogeneity hazard time emergence (beyond natural variability) regions targeted mining. Models combine climate‐induced changes circulation particle tracking predict transport early life stages (larvae) under Habitat suitability models assess consequences larval dispersal, refugia, identify vulnerable multiple species Engaging observing community support necessary data provisioning mainstream into development plans. To illustrate we focus mining International Seabed Authority, whose mandates include regulation all mineral‐related international waters protecting marine environment harmful effects However, achieving sustainability UN Sustainable Development Goals require integration consideration across policy sectors.

The Northeast Atlantic, a highly productive maritime area, has been exposed to wide range of direct human pressures, such as fishing, shipping, coastal development, pollution, and non-indigenous species (NIS) introductions, in addition anthropogenically-driven global climate change. Nonetheless, this regional sea supports high diversity habitats, whose functioning provides variety ecosystem services, essential for welfare. In 2017, OSPAR, the Atlantic Regional Seas Commission, delivered an assessment marine biodiversity Atlantic. This examined indicators separately identify changes biodiversity, but stopped short determining status many habitats. Here, we expand on work first time, semi-quantitative approach is applied evaluate holistically state across food webs, from plankton top predators, via fish, pelagic benthic including xeno-biodiversity (i.e. NIS). Our analysis reveals widespread degradation ecosystems particularly birds bottlenose dolphins, well habitats fish some regions. poor these components likely result cumulative effects activities, habitat destruction or disturbance, overexploitation, eutrophication, introduction NIS, Bright spots are also revealed, recent signs recovery bird communities harbour grey seal populations condition all components, novel webs NIS indicators, however, remains uncertain due gaps data, unclear pressure-state relationships, non-linear influence pressures indicators.

Tropical oceans are among the first places to exhibit climate change signals, affecting habitat distribution and abundance of marine fish. These changes stocks, subsequent impacts on fisheries production, may have considerable implications for coastal communities dependent food security livelihoods. Understanding tropical is therefore an important step towards developing sustainable, climate-ready management measures. We apply established method spatial meta-analysis assess species modelling datasets key targeted by Philippines capture fisheries. analysed under two global emissions scenarios (RCP4.5 RCP8.5) varying degrees fishing pressure quantify potential vulnerability target community. found widespread responses in pelagic particular, with abundances projected decline across much case study area, highlighting challenges maintaining face a rapidly changing climate. argue that sustainable can only be achieved through strategies allow mitigation of, adaptation to, pressures already locked into system near term. Our analysis support this, providing managers means identify hotspots, bright spots refugia, thereby supporting development plans.
