Cd is a non-degradable heavy metal pollutant with no known biological role. When taken up by living organisms from the environment, it causes extensive tissue damage. Here, we studied the effects of exposure to 20 mg/L−1CdCl2for 0, 24, 48, and 72 h on the renal tissue of marine catfish Arius arius. Cd uptake, metallothionein (MT) induction, microarchitectural alterations, DNA fragmentation, and caspase-3

Kuwait's marine biodiversity: Qualitative assessment of indicator habitats and species Mar. Pollut. Bull. (IF 4.049) Pub Date : 2020-12-24 N.J. Edmonds; A.S. Al-Zaidan; A.A. Al-Sabah; W.J.F. Le Quesne; M.J. Devlin; P.I. Davison; B.P. Lyons
The tropical waters of the Northern Arabian Gulf have a long history of maritime resource richness. High levels of biodiversity result from the complex matrix of coastal habitats, coral reefs and sea grass beds that characterise the region. Insight into the ongoing health of such habitats and the broader Kuwait maritime environment can be gauged by the status of indicator species found within these

Stress resistance for unraveling potential biopollutants. Insights from ballast water community analysis through DNA Mar. Pollut. Bull. (IF 4.049) Pub Date : 2020-12-24 Alba Ardura; Johannes Rick; Jose L. Martinez; Anastasija Zaiko; Eva Garcia-Vazquez
In marine settings, anthropogenic disturbances and climate change increase the rate of biological invasions. Predicting still undescribed invasive alien species (IAS) is needed for preparing timely management responses. We tested a strategy for discovering new potential IAS using DNA in a trans-equatorial expedition onboard RV Polarstern. During one-month travel, species inside ballast water experienced

Resilience of the zooplankton community in the northeast Gulf of Mexico during and after the Deepwater Horizon oil spill Mar. Pollut. Bull. (IF 4.049) Pub Date : 2020-12-24 Kendra L. Daly; Andrew Remsen; Dawn M. Outram; Heather Broadbent; Kurt Kramer; Kate Dubickas
We evaluated the resilience of the zooplankton community to the Deepwater Horizon oil spill in the northeast Gulf of Mexico, by assessing abundance, biomass, spatial distribution, species composition, and diversity indices during spring, summer, and winter, May 2010 to August 2014. SEAMAP samples collected between spring and summer 2005–2009 were analyzed as a baseline. Our results did not indicate
