Aquatic Ecology and Nature Conservation

Bnnouncement: Invasive mosquito species (Bachelor Thesis)

Start: summer 2017

Global trade and climate change promote the dispersal of invasive mosquito species including Oc. j. japonicus and Ae. Albopictus. Both species are known as vectors of different pathogens. However, knowledge on their ecology is limited. This study wants to investigate the occurrence of these species in the greater Oldenburg area and how they live.

Projects of graduation theses (Bachelor, Master)


Please note:

These suggested projects can be concretized in agreement with the students interedted. Of course, other projects are conceivable, in so far as they are relevant to the research fields of our group. Please do not hesitate to contact us in case you are interested in realizing a Bachelor, Master or Ph.D. thesis.


The projects offered are specified here: Themenangebote AG Gewässerökologie und Naturschutz.

 

Topic for a Bachelor- or Master-Thesis; research to be carried out in summer 2014:

Resting site studies: microclimate studies at sites with different types of vegetation and at different heights

Scientific background: Vector ecology, ecological parameter affecting the presence and development of mosquitoes or biting midges.

Impact of flooding on development success of different life stages of Culicoides (Diptera: Biting Midges)

Start: between December 2014 and January 2015

This laboratory study is focused on ecology of biting midges (Culicoides), which are vectors of viruses that may harm cattle and sheep. Several Culicoides species breed in moist substrates but their larvae and pupae are not able to swim or float. The study investigates the impact of flooding on the development success of larvae and pupae of different species.
