The COVID-19 pandemic has significantly impacted various aspects of life, including environmental conditions. Surface water quality (WQ) is one area affected by lockdowns imposed to control the virus's spread. Numerous recent studies have revealed considerable impact on surface WQ. In response, this research aimed assess in Ireland using an advanced WQ model. To achieve goal, six years monitoring data from 2017 2022 were collected for nine indicators Cork Harbour, Ireland, before, during, and after lockdowns. These include pH, temperature (TEMP), salinity (SAL), biological oxygen demand (BOD5), dissolved (DOX), transparency (TRAN), three nutrient enrichment indicators-dissolved inorganic nitrogen (DIN), molybdate reactive phosphorus (MRP), total oxidized (TON). results showed that lockdown had a significant indicators, particularly TEMP, TON, BOD5. Over study period, most within permissible limit except MRP, with exception during COVID-19. During pandemic, TON DIN decreased, while improved. contrast, COVID-19, at 7% sites deteriorated. Overall, Harbour was categorized as "good," "fair," "marginal" classes over period. Compared temporal variation, improved 17% period Harbour. However, no trend observed. Furthermore, analyzed model's performance assessing indicate model could be effective tool evaluating lockdowns' quality. can provide valuable information decision-making planning protect aquatic ecosystems.

In late December 2019, a novel coronavirus, COVID −19 originated in Wuhan city of China, and significant improvement not only the air quality but also water quality. Therefore, current study demonstrates changes parameters Ghaggar river, Punjab, India. The variations river have been examined during pre-, during, post-pandemic periods. maximum temperature for all monitoring stations was between 28 to 37°C pandemic period, whereas dissolved oxygen value varied from 3 7 mg/L. pH obtained reported be 7.7 8.0, except chhatbir station (7.6). biochemical demand found 18–53 Strong positive correlations were observed total coliform fecal pre (0.76) (0.89) Similar recorded BOD conductivity (0.75) (0.58)

Bangladesh’s aquaculture sector has contributed progressively to the nation’s economy over years, but COVID-19 pandemic impeded fish farmers’ access markets, reduced their production and sales capacity, resulted in lower income, increased food security vulnerability. This study assesses how affects smallholder farmers response strategies by employing data collected from 250 traders intensive fish-growing areas of Bangladesh. The results reveal that most experienced difficulty obtaining inputs, price those inputs skyrocketed during period, resulting several months decreased operations. As a result COVID-19, farm gate prices for silver carp, ruhu, common grass tilapia dropped 25%, 23%, 22%, 40%, respectively. On other hand, feed were found increase significantly. Reduced income farming sources triggered significant drop capital operations capacity improvement, leading insecurity. coping include buying market (vegetables, fruits, meat, milk, etc.), relying on less expensive or preferred food, purchasing credit, selling assets. Notably, due new mode marketing evolved as an adaptation strategy system, such use mobile phone (18%) Facebook/internet sell directly customer (16%). requires short-term financial assistance assist actors with challenges.

This paper explores how the COVID-19 pandemic affected science and tourism activities their governance in Antarctic Southern Ocean. The reduced ability of Treaty Parties to make decisions on policy issues placed a considerable burden researchers. Tourism was effectively suspended during 2020–2021 season heavily 2021–2022 but rebounded record levels 2022–2023. stimulated reflection practices facilitate dialog, especially through online events. Opportunities arose integrate innovations developed more permanently into practices, relation open science, reducing operational greenhouse gas footprints barriers access research facilitating data sharing. However, as well long-term impacts arising directly from pandemic, an assemblage major geopolitical drivers are also play and, combined, these signal weakening exceptionalism early Anthropocene.

Abstract Indo‐Pacific humpback dolphins form a resident population off the east coast of Leizhou Peninsula (LZP) in South China. The most recent study suggested ~1,500 individuals this area, making one only two populations species exceeding 1,000 individuals. However, demographic information regarding has been lacking since 2012. Using 5‐year (2019–2023) photo‐identification data set, we examined key parameters LZP population, namely apparent survival and size, using multistate capture‐recapture analyses. Annual probabilities (φ) changed over time, fluctuating between 0.942 0.961 for adults, 0.787 0.837 juveniles. Jolly‐Seber model analyses resulted highly comparable noncalf size estimates from 2020 to 2023 ( = 479, SE 28; 2021 458, 29; 2022 481, 27; 446, 31). By reviewing available information, conclude that previously overestimated. time‐dependent survivals seemingly reflect dynamic development anthropogenic disturbance during pandemic period. We propose status should be re‐evaluated, especially postpandemic era when human activities came back “normal” levels.

Differences in fish assemblages’ composition and their relationship with the environmental variables were analyzed Urías estuarine system, Mexican North Pacific. Environmental catches recorded bimonthly between June 2018 November 2021, including a period before during COVID-19 pandemic. Multivariate analyses performed studied area to define zones based on environmental, biotic, abiotic characteristics effect of these assemblages. Two identified, an mangrove forest surf zone coastal outside system. Fish composition, biomass, diversity (α β) evaluated among factors (before–during COVID-19), climatic seasons, zones. A total 5947 individuals 41 species collected using beach seines as fishing gear. The structure assemblages was different periods. Abiotic (temperature, salinity, matter suspended), biotic (mangrove area), temporal (season before–during COVID-19) had biomass α diversity, while results β only indicate changes nestedness component lockdown. These change periods, which might be consequence limitation human activities derived from pandemic, changes, or combination both effects.
