Interactive effects of temperature, nutrient level and sandprawns (Kraussillichirus kraussi) ecosystem engineering on microplankton community structure
Published 2025“…Previous research has proposed that the below-ground burrow systems of K. kraussi function as a biofiltration system, whereby active bi-directional water pumping by sandprawns causes phytoplankton cells to be adsorbed onto the walls of their burrows, thus assisting in limiting phytoplankton proliferation associated with eutrophication. …”

Effects of demersal trawling on marine infaunal, epifaunal and fish assemblages: studies in the southern Benguela and Oslofjord
Published 2014“…Infauna were re-sampled at all four sites immediately after trawling (post-impact), 14 days and 64 days after the impact to monitor recovery of infaunal populations. Multivariate analyses comparing the impact sites with paired control sites for each sampling occasion showed no significant differences in infaunal assemblages at any stage of the experiment. …”
