Present Graduate Students

Lauren Ellis, M.Sc. candidate (2009-)
B.Sc. (honours) Biology, Carleton University, Ottawa, Ontario. 2008.
Project: Settlement and biodiversity of marine invertebrates on shallow cobble habitats of the southwest Bay of Fundy: Test of a new monitoring tool and of the decreased-substrate settlement-intensification hypothesis.

My project will focus on identifying the effect of surrounding substrate on settlement and its implications on biodiversity. A new diversity monitoring tool will be used to gather data about juvenile settlement patterns. This will result in a good estimation of the local benthic fauna from shallow muddy and rocky sites in the Bay of Fundy as well as the opportunity to increase the effectiveness of the tool and ease of use. The knowledge gained from this project will facilitate future biodiversity studies using the monitoring tool and shed light on the settlement patterns of select marine invertebrates, thus improving conservation management efforts.

Guðjón Már Sigurðsson, Ph.D. candidate, UNBSJ (2009-)
M.Sc. in Marine Biology also at the University of Iceland in 2009
MSc Thesis: Gelatinous zooplankton in Icelandic coastal waters with special reference to the scyphozoans Aurelia aurita and Cyanea capillata.
BSc. in Biology at the University of Iceland in 2007 .
PhD Project: Lobster settlement: patterns, processes and importance to recruitment.

My project is on lobster settlement, using collectors to look at spatial and temporal patterns of larval settlement in the south western bay of Fundy. My work will also involve finding out if lobster settlement is strictly confined to specific sites of suitable habitat or if settlement also occurs in other areas, for example in deeper waters.
