Aggregation into groups may affect performance of individuals through the balance and strength of facilitative versus competitive interactions. We studied in situ how seasonal variation in abiotic environment affects this balance for blue mussels, a semi-sessile species. We hypothesize that seasonal …

Anthropogenic changes to estuaries, usually highly productive systems, may result in increased turbidity levels, suppress pelagic primary production and negatively affect ecosystem functions. The Ems-Dollard estuary, enclosed between the Netherlands and Germany, is such an estuary with a long history …

Thermal disinfection is probably the oldest water treatment method ever used. Similarly to other disinfection processes, it targets the inactivation of pathogenic (micro)organisms present in water, wastewater and other media. In this work, a pilot-scale continuous-flow thermal disinfection system was …

The turbidity in Lake Markermeer limits the primary production by phototrophic algae and the growth of plants. In turn, this limits the amount of fish and other organisms that live in and around Lake Markermeer in its food sources. To determine if there are organisms that limit the resuspension, a survey …

The seeding of mussel seeds is an important factor within the mussel culture as losses can be as high as 75% within the first 4 weeks after seeding. Therefore it is important to get more knowledge about the factors that can cause mortality within the first weeks after seeding. With seeding high local …

Nutrient enrichment, scientifically known as eutrophication, is a worldwide problem. Eutrophication is one of the main drivers for cyanobacteria blooms. Cyanobacteria blooms can have a negative effect on ecology, economy and human health, as a result of to the ability of some species to release toxins. …
