||Ram Mountain, early June 2008. The
ewes (E13, 9 years old with yellow T collar, and J5,
4-year-old) are mother and
daughter. E13 had already lost her lamb,
while J5 was pregnant. She gave birth about 10 days
later, but her lamb died in winter.
E13 disappeared overwinter. In 2009-2014, none of J5's 6
lambs survived to 1 year of age. Not the best mother.
Her daughters U12 and V16, born in 2015 and 2016,
however, survived to 2017!

Here are an adult female (#8) and her son (#15), at Wilsons Promontory National Park, Victoria, August 2008. In 2009, #8 had a son and the next year she had a daughter. In 2011 her pouch young disappeared when aged a few months. #15 likely emigrated.

|Ewe # 132 at Sheep River, Alberta, in 1986 at 2 years of age (left) and in 2000 at 16 years. She disappeared the following winter. She produced 14 lambs, of which 5 survived to 1 year of age.|
Animal ecology: individual reproductive success, reproductive strategy, population dynamics and conservation of mammals
Research GoalsMy research seeks to understand how individual differences affect reproductive success, reproductive strategies and population dynamics of large mammals. Large mammals are long-lived, highly iteroparous, and their population dynamics often show time lags. Therefore, long-term monitoring of marked individuals is the best approach to test theories on their reproductive success and population dynamics. My students and I produce knowledge useful for wildlife management and for the conservation of biodiversity. With mixed success, we argue that evolutionary ecology is important for conservation and for wildlife management.
Current Research Projects:Evolutionary ecology and population dynamics of bighorn sheep (Ovis canadensis). With several students and collaborators, I monitor the Ram Mountain population in Alberta. We have marked over 1100 bighorns at Ram Mountain since 1972. This research has identified the factors that affect individual reproductive success, reproductive strategy, and population dynamics. We have quantified the selective effects of trophy hunting and exposed the possibility that they may have negatively affected population dynamics. Major collaborators are Jon Jorgenson of Alberta Fish & Wildlife, David Coltman of the University of Alberta and Fanie Pelletier of the Université de Sherbrooke. This research includes an analysis of long-term data on harvested rams in Alberta.
"Blue-blue" (#35T), 11 years old, visiting the trap at Ram Mountain, July 1999. He fathered at least 13 lambs, but was shot illegally in September 1999. Blue-blue was known for his love of salt and his lack of respect for handlers in the trap.

2011. In late July 2013, she gave up on #580: it disappeared
from her pouch. Female #403 did the same in 2014, her pouch
young disappeared in late August.

# 236 (green collar) and # 253
(red collar) are adult females, both nursing young-at-foot as
of March 2013. Neither had a new pouch young in 2013 and
253 died in August.
# 28 (White-Red ear tags) is a
young male, first tagged in his mother's pouch in August
2008. Behind him is # 206 (white-pink), a 2-year-old
female. Both roos were still residents as of November
The study population has a
very high density, 3-6/Ha. We are currently monitoring
about 230 marked roos at this site.
