1. Zooplankton response to cyanotoxins
Abstract : Mass development of cyanobacteria (blue-green algae) is common in many lakes and coastal waters worldwide as a result of an increased nutrient loading. These blooms of cyanobacteria are undesirable for several reasons; thick mats of algae and unpleasant odour reduces the recreational values, bad taste reduces the quality of drinking water and the potent toxins produced by some species of cyanobacteria endanger human health.

2. Non-indigenous zooplankton : the role of predatory cladocerans and of copepods in trophic dynamics
Abstract : Human-mediated introductions of non-indigenous species now threaten to homogenize the biota of the Globe, causing huge economic and ecological damage. This thesis studies the ecological role of 3 invasive planktonic crustaceans, the omnivorous copepod Acartia tonsa (western Atlantic and Indo-Pacific) and the predatory cladocerans, Cercopagis pengoi (Ponto-Caspian) and Bythotrephes longimanus (Eurasian).

While the issue of food quality in clear water lakes has received great recent attention, studies on food quality for zooplankton in humic lakes are scarce. READ MORE
