The deep sea encompasses the largest ecosystems on Earth. Although poorly known, seafloor provide services that are vitally important to entire ocean and biosphere. Rising atmospheric greenhouse gases bringing about significant changes in environmental properties of realm terms water column oxygenation, temperature, pH food supply, with concomitant impacts deep-sea ecosystems. Projections suggest abyssal (3000–6000 m) temperatures could increase by 1°C over next 84 years, while habitats...
Abstract We develop a novel class of measures to quantify sample completeness biological survey. The is parameterized by an order q ≥ 0 control for sensitivity species relative abundances. When = 0, abundances are disregarded and our measure reduces the conventional completeness, that is, ratio observed richness true (observed plus undetected). 1, coverage (the proportion total number individuals in entire assemblage belongs detected species), concept developed Alan Turing his cryptographic...
Mora and colleagues show that ongoing greenhouse gas emissions are likely to have a considerable effect on several biogeochemical properties of the world's oceans, with potentially serious consequences for biodiversity human welfare.
Abstract Coastal eutrophication and hypoxia remain a persistent environmental crisis despite the great efforts to reduce nutrient loading mitigate associated damages. Symptoms of this have appeared spread rapidly, reaching developing countries in Asia with emergences Southern America Africa. The pace changes underlying drivers not so clear. To address gap, we review up-to-date status mechanisms global coastal oceans, upon which examine trajectories over 40 years or longer six model systems...
Ocean manipulation to mitigate climate change may harm deep-sea ecosystems.
Although the impacts of nutrient pollution on coral reefs are well known, surprisingly, no statistical relationships have ever been established between water quality parameters, biodiversity and cover. Hong Kong provides a unique opportunity to assess this relationship. Here, coastal waters monitored monthly since 1986, at 76 stations, providing highly spatially resolved dataset including 68 903 data points. Moreover, robust species richness (S) is available from more than 100 surveyed...
We analyzed published downcore microfossil records from 150 studies and reinterpreted them an ecological degradation perspective to address the following critical but still imperfectly answered questions: (1) How is timing of human-induced marine ecosystems different among regions? (2) What are dominant causes degradation? (3) can we better document natural variability thereby avoid problem shifting baselines comparison as progresses over time? The results indicated that: in systems began...
In this paper, we outline the need for a coordinated international effort toward building of an open-access Global Ocean Oxygen Database and ATlas (GO 2 DAT) complying with FAIR principles (Findable, Accessible, Interoperable, Reusable). GO DAT will combine data from coastal open ocean, as measured by chemical Winkler titration method or sensors (e.g., optodes, electrodes) Eulerian Lagrangian platforms ships, moorings, profiling floats, gliders, ships opportunities, marine mammals, cabled...
A major research question concerning global pelagic biodiversity remains unanswered: when did the apparent tropical depression (i.e., bimodality of latitudinal diversity gradient [LDG]) begin? The bimodal LDG may be a consequence recent ocean warming or deep-time evolutionary speciation and extinction processes. Using rich fossil datasets planktonic foraminifers, we show here that unimodal (or only weakly bimodal) gradient, with plateau in tropics, occurred during last ice age has since then...
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...
Per- and polyfluoroalkyl substances (PFAS) are synthetic long-lasting chemicals. Marine sediment is a major repository for PFAS in the environment; accordingly, this work investigated 45 legacy emerging samples of surface sediments cores (1940s-2020s) collected Pearl River outlets, its estuary, adjacent northern South China Sea (NSCS), one global pollution hotspots. The range total concentrations from river outlets NSCS was 244-14400 pg/g dry weight (dw) 31.6-363 dw, respectively. In cores,...
We investigated the deep-sea fossil record of benthic ostracodes during periods rapid climate and oceanographic change over past 20,000 years in a core from intermediate depth northwestern Atlantic. Results show that community "collapses" occur with faunal turnover up to 50% major climatically driven changes. Species diversity as measured by Shannon-Wiener index falls 3 low 1.6 these events. Major disruptions communities commenced Heinrich Event 1, Inter-Allerød Cold Period (IACP: 13.1 ka),...
High tropical and low polar biodiversity is one of the most fundamental patterns characterising marine ecosystems, influence temperature on such latitudinal diversity gradients increasingly well documented. However, temporal stability quantitative relationships among diversity, latitude largely unknown. Herein we document zooplankton species at four time slices [modern, Last Glacial Maximum (18,000 years ago), last interglacial (120,000 Pliocene (~3.3-3.0 million ago)] show that, although...
A benthic microfaunal record from the equatorial Atlantic Ocean over past four glacial-interglacial cycles was investigated to understand temporal dynamics of deep-sea latitudinal species diversity gradients (LSDGs). The results demonstrate unexpected instability and high amplitude fluctuations in tropical deep ocean that are correlated with orbital-scale oscillations global climate: Species is low during glacial interglacial periods. This implies climate severely influences diversity, even...
Poor water quality driven by increased nutrients is the main cause of coral diversity loss in southern China’s Greater Bay Area.
Abstract Motivation Traits are increasingly being used to quantify global biodiversity patterns, with trait databases growing in size and number, across diverse taxa. Despite interest a trait‐based approach the of deep sea, where impacts human activities (including seabed mining) accelerate, there is no single repository for species traits deep‐sea chemosynthesis‐based ecosystems, including hydrothermal vents. Using an international, collaborative approach, we have compiled first...
Direct observations of marine ecosystems are inherently limited in their temporal scope. Yet, ongoing global anthropogenic change urgently requires improved understanding long-term baselines, greater insight into the relationship between climate and biodiversity, and knowledge evolutionary consequences our actions. Sediment cores can provide this understanding by linking data on responses of marine biota to reconstructions past environmental climatic change. Given continuous...
