I am a post-doctoral associate working with Daniel Ruzzante. I am interested
in processes causing speciation and the underlying mechanisms and factors
limiting gene flow and/or promoting divergence among closely related
populations. I work on all sorts of critters but currently focus on the
population connectivity of White Hake (Urophycis
tenuis) from the Canadian north Atlantic. This close relative
of cod and haddock has been over exploited to the point where its fishery
was stopped in 1994, with seemingly little recovery in sight.

I am interested in employing molecular tools in an attempt to better
understand what past and present factors are responsible for shaping
contemporary genetic diversity within species of the family Galaxiidae
inhabiting Patagonia, South America. The approach uses a variety of
molecular markers within several contexts, including phylogeography,
taxonomy and population genetics, to address questions relating to
evolution, biogeography and conservation biology.

My research involves the analysis of diversity in body shape, meristic traits
and molecular markers in Galaxias maculatus, a southern hemisphere fish
species native to Patagonia. The populations studied are present in two
important drainages of Argentina: The Negro (Northern Patagonia) and the
Santa Cruz River drainages (Southern Patagonia). G. Maculatus exhibits a
high degree of plasticity in life history, with diadromous, landlocked
lacustrine and landlocked riverine populations and the two river drainages
studied differ in the types of G. maculatus populations they harbour. We
expect the results from this project to assist in the understanding of the
relative importance of migratory behaviour (gene flow and population
structure) for the establishment of landlocked populations along the two
drainages.

I am
interested in salmonid ecology, population regulation, the impacts of
non-native fishes and recreational fisheries. My research at Dalhousie is
focused on estuarine and coastal near-shore mortality in Atlantic salmon,
namely the first 4-8 weeks after they leave their natal rivers and begin
the marine-phase of their anadromous life history.

I am interested in examining the role
that the landscape plays on the connectivity among populations of Lake
trout (Salvelinus namaycush) in a pristine system in Labrador. I am also
interested in determining how human induced changes to the landscape alter
the genetic structure of these Lake trout.

I’m interested in the application of genetics for conservation and
management. I will be using genetic and demographic data, along with
population genetics theory to infer the effective population size (Ne) of a
population of Atlantic salmon (Salmo salar) in Newfoundland.

My research interests are centered on elucidating the genetic and
demographic context for contemporary evolution, and its relevance for
management and conservation. I have addressed these questions in a wide
range of study organisms, such as corals and their endosymbiotic algae and,
more recently, Atlantic salmon. This research typically employs a
combination of molecular genetic markers, demographic analyses and
population & quantitative genetics theory. My current involvement with
the lab focuses on empirical estimation of the effective size of a
metapopulation.

I am a 3rd year biology student here at Dalhousie and am particularly
interested in conservation biology and veterinary medicine. In Dr.
Ruzzante's lab I am extracting and amplifying DNA from samples of brook
trout (species Salvelinus fontinalis) that were collected from streams
along the North Mountain in Nova Scotia.

My name is Abby van der Jagt and I am a lab technician for Dr. Ruzzante.
I have been working here since January of 2008. It is my job to help
out with various projects that are on the go. I mainly concentrate on
microsatellite research, but I am also responsible for making sure the lab
is running smoothly.
