1. Herbivores effect on coral reefs : relationships between sea urchins, coral health and algae cover
Kandidat-uppsats, SLU/Dept. of EcologySammanfattning : Coral reefs are vital to marine ecology. The population dynamic on coral reefs are complex and sensitive to natural and anthropogenic changes. Various factors can affect the population dynamic and inflict change. Coral bleaching is threatening coral reefs worldwide and is a hot topic in today’s climate challenges. LÄS MER
2. Paleoecology and sedimentology of the Upper Cretaceous (Campanian), marine strata at Åsen, Kristianstad Basin, Southern Sweden, Scania

A diverse fossil fauna was collected from Campanian deposits from a ca. 4.15m thick section during June-August 2010-2012. LÄS MER
3. Population genetic structure and connectivity of the abundant sea urchin, Diadema setosum around Unguja island (Zanzibar).
Kandidat-uppsats, Institutionen för livsvetenskaperSammanfattning : The distribution and abundance of many coral reef organisms are affected by their predator’s distribution and abundance. Loss of predators may cause a shift in species compositions that will cascade down to other ecological processes on the reef. LÄS MER
