Caleb Hasler is a Ph.D. candidate currently working
with Dr. Steven Cooke, at Carleton University
(Ottawa, Ontario). The aim of Caleb's research
is to study the impacts of hydropower infrastructure
and operations on fish habitat quality and associate
impacts on organismal condition, behaviour and
physiology.
Caleb's work focuses around a regulated river
on Vancouver Island and an imperiled stock of
Chinook salmon. His work uses a variety of approaches
discussed in Dr. Cooke's paper "Conservation
Physiology", including telemetry (radio and
CEMG), non-lethal physiolgical biopsies, and thermologgers.
Caleb also has interest in the use of GIS in biological
sciences, as well as the development of new techniques
for tracking animals in their environment.
