April Hedd, Post
Doctoral Fellow
My research interests focus on the
ecology and conservation of vertebrate predators and their role in
marine ecosystems. Through field studies in the Southern Ocean, and
on the west and east coasts of Canada I have investigated the
ecology and behavioural strategies of a variety of seabirds to
understand both natural and anthropogenic factors influencing
reproduction and survival. During my doctoral research at University
of Tasmania with Dr. Rosemary Gales, we used a variety of archival
and telemetric devices to study the distribution and behaviour of
Shy albatrosses at sea as a means of understanding their
vulnerability to, and ultimately reducing rates of incidental
capture in long-line fisheries. At the Centre for Wildlife Ecology
at Simon Fraser University Dr. Douglas Bertram and I used long-term
datasets to examine the influence of ocean climate variation on the
foraging ecology and reproductive performance of planktivorous
Cassin's auklets and piscivorous Rhinoceros auklets off the coast of
British Columbia. Warm ocean conditions in the mid- to late-1990s
apparently resulted in poor availability of key forage species, and
this was expressed at higher trophic levels by poor seabird
reproductive performance. As an NSERC Post-doctoral Fellow with
Prof. Montevecchi at Memorial University, my current research
focuses on ecology and distribution of Leach's storm-petrel, the
most abundant breeding seabird in eastern North America. Despite its
abundance, its small size (50 g), burrow nesting and nocturnal
habits result in it being poorly known. We are using both
conventional and chemical (stable-isotope) analyses to study the
breeding ecology, diets and trophic relationships of Leach's
storm-petrel throughout its annual cycle. In collaboration with the
Canadian Wildlife Service in St. John's we have also initiated a
long-term mark-recapture program in the Witless Bay Seabird
Ecological Reserve. When combined within a framework involving
piscivorous seabirds (see Prof. Montevecchi's page), we anticipate
that our research with the planktivorous Leach's storm-petrel will
shed light on mechanisms driving change within the Newfoundland
Grand Banks ecosystem.

Chantelle Burke,
Research Assistant; M.Sc. Student
I began as a research assistant
with Dr. Montevecchi in 2000 after studying marine environmental
studies at the Marine Institute (Memorial University of
Newfoundland). During this time I became involved in research
investigating the effects of oil and gas platforms on seabirds
inhabiting the Grand Banks of Newfoundland. During 1999-2003, I
conducted monthly surveys to offshore platforms on the Grand Banks
to document the occurrence of seabirds on the Grand Banks throughout
the year and to conduct independent monitoring to determine whether
seabirds are being killed at offshore platforms. In 2004, I entered
the M.Sc. program in Cognitive and Behavioral Ecology at Memorial
under the supervision of Dr. Bill Montevecchi. Our research focuses
on the foraging ecology of Common Murres and Atlantic Puffins in
relation capelin availability in the Northwest Atlantic. I assess
capelin availability using at-sea measurements (trawl and
hydroacoustic) of the distribution, composition and abundance of
prey over a meso-scale survey centered on Funk Island, the largest
breeding colony in the Northwest Atlantic. Concurrent measurements
of diet (via chick diets), foraging effort and chick condition are
gathered at Funk Island to assess the responses of these two avian
predators to changes in capelin conditions. This research is a
component of a large, multi-disciplinary ecosystem project,
supported by NSERC, investigating the importance of capelin in the
Northwest Atlantic.

Dave Fifield, Canadian Wildlife Service;
M.Sc. Student
A native Newfoundlander, I received
a B.Sc. in Computer Science from Memorial University of Newfoundland
in 1987 and worked as a programmer and support technician for the
university for seven years. In 1990, I became interested in birds
and in subsequent years contributed to a variety of seabird research
projects. I entered the M.Sc. program in Cognitive and Behavioral
Ecology at Memorial in September 2004 under the supervision of Dr.
Bill Montevecchi and Dr. Greg Robertson. Our research focuses on
winter ecology of seabirds; the effect of colony and demographic
variables on patterns and timing of winter movement, resource usage
and geographical association. Although much is known about breeding
season ecology of seabirds, we know relatively little about
interactions with their environment during winter. Our
investigations include the use of light-based geolocation loggers,
stable isotope analysis and banding returns at Northern Gannet
colonies on Bonaventure Island, PQ, Funk Island, NL and at Cape St.
Mary's, NL. I am particularly interested in quantitative analysis
and the efficient design of databases for ecological research.

Paul Regular, Ph.D. Student
I grew up in the town of Hampden,
Newfoundland, where my
fascination with Newfoundland wildlife began.
I spent much of my time outside observing local
birds, fish and mammals, educating myself about their behaviour and
interactions.
Knowing that I wanted to work with wildlife, I moved to St. John’s
and completed my BSc (Honours) degree in Biology at Memorial
University of Newfoundland (MUN; 2002-2006). During my
undergraduate, my interest quickly focused to seabirds after
conducting my Honours research on auklet colonial behaviour under
the supervision of Dr. Ian Jones on Buldir Island, Aleutian Islands,
Alaska.
After completing my B.Sc., I was hired by the
Nature Conservancy of Canada (NCC) and Environment Canada (EC) to
work on a research project dealing with common murre population and
breeding trends at Cape St. Mary’s, Newfoundland. Dr. William
Montevecchi and Dr. Gregory Robertson were my supervisors for much
of this work, so it was a natural move after finishing my contract
with NCC and EC to enter the PhD programme in Cognitive and
Behavioural Ecology at MUN with Dr. Montevecchi and Dr. Robertson as
my supervisors (2007). The nature of this program and the research
focus of my supervisors allow me to nurture my interest in seabird
behavior and ecology. Our research focuses on the foraging ecology
of breeding Common Murres. I am specifically interested in
contrasting the foraging strategies of Common Murres breeding at a
large offshore colony (Funk Island, Funk Island Ecological Reserve)
and a small inshore colony (Gull Island, Witless Bay Ecological
Reserve). Oceanographic conditions and prey distributions at these
colonies are drastically different. Consequently foraging tactics
and food web dynamics may differ greatly at these two sites. We
will compare the foraging tactics of Common Murres from both islands
using bird-born activity recorders, colony based and vessel based
observations. In the process of doing this exciting data heavy
research, I have developed a keen interest in statistical analyses,
and somewhere between making posters and power points, I have grown
increasingly fond of graphic design.

My research
interests revolve around the understanding of the processes and
mechanisms that structure and regulate natural communities. I am
particularly interested in putting this knowledge to work for
practical purposes, e.g. sustainable use of natural resources
and conservation. My research involves evaluating the role of top
predators in marine systems such as marine mammals, seabirds and
large fish. I received a Licentiate in Biology degree from the
University of Patagonia, where I studied the effects of fisheries
using a large skate as a biological indicator of changes in the
community. While in Patagonia, I also collaborated in projects
devoted to the behavior and population dynamics of small cetaceans
and sea lions. In 2005 I started my MSc at Memorial University,
under the supervision of Drs Montevecchi and Koen-Alonso. My MSc
thesis explored the relationship between prey availability and diet,
using the common murre-capelin interaction as a case study. In 2007
I entered the PhD program in CABE, and my current research is trying
to elucidate the potential effects that harp seals may have on the
non-recovery of the cod stocks off Newfoundland, a topic as
controversial as open to scrutiny. My PhD work involves developing
trophodynamic models that puzzle together capelin, cod and harp
seals, three key species in the Newfoundland marine community.

McFarlane Tranquilla, Ph.D. Student
My research
interests in avian ecology started while doing my BSc. at the
University of New Brunswick, where I spent my summers studying
songbird territory size in the blackfly-infested forests of New
Brunswick. During this time, I was lucky enough to spend some time
on Kent and Machias Seal Islands, where I was immediately captivated
by the idea of working on seabirds. Since then, I have happily
weathered remote fieldwork on rocky coastlines and stormy seabird
islands, on both east and west coasts of Canada, catching and
observing seabirds, sticking my arms into seabird burrows (up to the
armpits in dirt) and have been chomped, scratched, and regurgitated
upon by puffins, razorbills, murres, murrelets, auklets, and
petrels.
Fieldwork aside,
my research interests are broadly centered on seabird ecology,
physiology, and conservation. During my MSc. at the
Center for
Wildlife Ecology at Simon Fraser University,
I studied breeding timing, egg production, and stress responses of
Marbled Murrelets. Since
finishing my masters, I have worked in association with the Canadian
Wildlife Service managing seabird databases, and writing and editing
scientific papers, technical reports, and handbooks discussing the
ecology and biology of marine birds.
I am delighted to
be starting PhD studies in the Montevecchi lab at MUN in association
with the
IPY project.
My research will focus on winter movement ecology of Thick-billed
and Common Murres using data collected from tracking devices. I
also plan to integrate winter movement ecology with trophic level
associations and murre body condition.
