Human life comes to a standstill as many countries shut themselves off from the work due novel coronavirus disease pandemic (COVID-19) that hit world severely in first quarter of 2020. All types industries, vehicle movement, and people's activity suddenly halted, perhaps for time modern history. For long time, it has been stated various literature increased industrialization anthropogenic activities last two decades polluted atmosphere, hydrosphere, biosphere. Since industries have month or more parts world, is expected show some improvement prevailing conditions aforementioned spheres environment. Here, with help remote sensing images, this quantitatively demonstrated surface water quality terms suspended particulate matter (SPM) Vembanad Lake, longest freshwater lake India. The SPM estimated based on established turbidity algorithm Landsat-8 OLI images showed concentration during lockdown period decreased by 15.9% average (range: −10.3% 36.4%, up 8 mg/l decrease) compared pre-lockdown period. Time series analysis satellite image collections (April 2013 – April 2020) quantified 2020 lowest 11 out 20 zones lake. When preceding years, percentage decrease 34% previous minima.

Identifying the consequences of ocean sprawl for sedimentary habitats

Journal of Experimental Marine Biology and Ecology, Год журнала: 2017, Номер 492, С. 31 - 48

Опубликована: Фев. 16, 2017

Extensive development and construction in marine coastal systems is driving a phenomenon known as “ocean sprawl”. Ocean sprawl removes or transforms habitats through the addition of artificial structures some most significant impacts are occurring sedimentary environments. Marine sediments have substantial social, ecological, economic value, they rich biodiversity, crucial to fisheries productivity, major sites nutrient transformation. Yet impact ocean on environments has largely been ignored. Here we review current knowledge ecosystems arising from structures. Artificial alter composition abundance wide variety sediment-dependent taxa, including microbes, invertebrates, benthic-feeding fishes. The effects vary by structure design configuration, well physical, chemical, biological characteristics environment which placed. mechanisms include placement loss, habitat degradation, modification sound light conditions, hydrodynamic changes, organic enrichment material fluxes, contamination, altered biotic interactions. Most studies inferred mechanism based descriptive work, comparing physical processes at various distances Further experimental needed identify relative importance multiple demonstrate causal relationships. Additionally, past focused relatively small scale, independently other that occurring. There need quantify large-scale cumulative proliferate. We highlight for comprehensive monitoring using robust survey designs outline research strategies understand, protect face rapidly changing environment.

Impacts of artificial light at night in marine ecosystems—A review

Global Change Biology, Год журнала: 2022, Номер 28(18), С. 5346 - 5367

Опубликована: Май 18, 2022

Abstract The globally widespread adoption of Artificial Light at Night (ALAN) began in the mid‐20th century. Yet, it is only last decade that a renewed research focus has emerged into its impacts on ecological and biological processes marine environment are guided by natural intensities, moon phase, light dark cycles daily spectra alterations. field diversified rapidly from one restricted to handful vertebrates, which have been quantified across broad array coastal habitats species. Here, we review current understanding ALAN diverse ecosystems. presents state knowledge key ecosystems (sandy rocky shores, coral reefs pelagic) taxa (birds sea turtles), introducing how can mask seabird turtle navigation, cause changes animals predation patterns failure spawning synchronization, as well inhibition zooplankton Diel Vertical Migration. Mitigation measures recommended, however, while strategies for mitigation were easily identified, barriers implementation poorly understood. Finally, point out gaps if addressed would aid prediction realm.

Marine Litter Impact on Sandy Beach Fauna: A Review to Obtain an Indication of Where Research Should Contribute More

Microplastics, Год журнала: 2022, Номер 1(3), С. 554 - 571

Опубликована: Сен. 9, 2022

In order to identify how research contributes the knowledge of marine litter as a pressure on beaches, we reviewed interactions beach fauna with this pollutant. Entanglement pinnipeds in fishing gear, negative correlations between macroinvertebrates abundance and sediment pollution, presence plastic surrounding burrows were primary evidence interacting stranded litter. Ingestion represents main body research; microplastic uptake by invertebrates has been studied laboratory experiments field collections report polymers tissues. natural context, higher urbanization beaches concentration microplastics organs bivalves. This approach currently constitutes direction, but ecotoxicological assays are emerging prospects assess effects exposure microplastics. Beached macroplastics entangle entrap vertebrates, studies have reported increasing seals sea turtles. Changes nesting feeding behavior resident transient organisms shown typical early warning indicators impacts. The focus fauna–litter holds terrific potential for citizen science projects, which finally becomes powerful driver towards environmental awareness sandy beaches.
