Publikováno v: Frontiers in Microbiology, Vol 13 (2022)

Fish farming in sea cages is a growing component of the global food industry. A prominent ecosystem impact of this industry is the increase in the downward flux of organic matter, which stimulates anaerobic mineralization and sulfide production in un

Impaired Short-Term Functioning of a Benthic Community from a Deep Norwegian Fjord Following Deposition of Mine Tailings and Sediments

Autor: Lisa Mevenkamp, Tanja Stratmann, Katja Guilini, Leon Moodley, Dick van Oevelen, Ann Vanreusel, Stig Westerlund, Andrew K. Sweetman

Publikováno v: Frontiers in Marine Science, Vol 4 (2017)

The extraction of minerals from land-based mines necessitates the disposal of large amounts of mine tailings. Dumping and storage of tailings into the marine environment, such as fjords, is currently being performed without knowing the potential ecol

Chemoautotrophic carbon fixation rates and active bacterial communities in intertidal marine sediments.

Autor: Henricus T S Boschker, Diana Vasquez-Cardenas, Henk Bolhuis, Tanja W C Moerdijk-Poortvliet, Leon Moodley

Publikováno v: PLoS ONE, Vol 9, Iss 7, p e101443 (2014)

Chemoautotrophy has been little studied in typical coastal marine sediments, but may be an important component of carbon recycling as intense anaerobic mineralization processes in these sediments lead to accumulation of high amounts of reduced compou

Effects of low crude oil chronic exposure on the northern krill (Meganyctiphanes norvegica)

Publikováno v: Journal of Experimental Marine Biology and Ecology. 500:120-131

Chronic oil pollution related to gas and oil drilling activities is increasing in the sea due to the rising offshore petroleum industry activity. Among marine organisms, zooplankton play a crucial role in the marine ecosystem and therefore understand

Effects of chronic crude oil exposure on early developmental stages of the Northern krill (Meganyctiphanes norvegica)

Autor: Sreerekha Ramanand, Anna Ingvarsdottir, Evgenia Dunaevskaya, Marianne Nilsen, Renée Katrin Bechmann, Elisa Ravagnan, Geraint A. Tarling, Leon Moodley, Steinar Sanni, Maj Arnberg, Stig Westerlund

Publikováno v: Journal of Toxicology and Environmental Health, Part A. 80:916-931

Rising oil and gas activities in northern high latitudes have led to an increased risk of petroleum pollution in these ecosystems. Further, seasonal high UV radiation at high latitudes may elevate photo-enhanced toxicity of petroleum pollution to mar

Tolerance of Infaunal Benthic Foraminifera for Low and High Oxygen Concentrations

Autor: Christoph Hess, Leon Moodley

Publikováno v: The Biological bulletin. 183(1)

Ammonia beccarii is irregularly distributed in the subtidal sediment of the southern North Sea, with substantial numbers occurring as deep as 35 cm below the water-sediment interface. Deep infaunal specimens are insensitive to high oxygen concentrati

The diet of cavity sponges on the narrow fringing reefs of Cura double dagger ao, Caribbean was studied. The origin and resources of the bulk food of these sponges, i.e., dissolved organic matter (DOM), were identified using stable carbon and nitroge

Spatial distribution of detrital resources determines the outcome of competition between bacteria and a facultative detritivorous worm

Autor: Leon Moodley, Paul van Nugteren, Matthijs Vos, Carlo H. R. Heip, Jack J. Middelburg, Peter M. J. Herman

Scopus-Elsevier

Macrobenthic deposit feeders and bacteria compete for the same detrital food resources. We hypothesize that the spatial scale at which food is distributed in the sediment is an important factor determining the outcome of this competition. Macrobenthi
