 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 J5 lost her lamb at birth and the one she had in 2010 died in June.  Her male lamb born in 2011, however, survived to late September.

 Eastern grey kangaroos can sometimes be caught with a 5-m jabstick!
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. #15 disappeared and may have emigrated.

Ewe # 132 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.

 

Research Program

Animal ecology: individual reproductive success, reproductive strategy, population dynamics and conservation of mammals

 

Research Goals

My research seeks to understand how individual differences affect reproductive success 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 testing 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 two populations in Alberta.  We have marked over 750 bighorns at Sheep River since 1981, and over 1000 at Ram Mountain since 1972.  This research has identified the factors that affect individual reproductive success, reproductive strategy, and population dynamics.  Recently, we have quantified the selective effects of trophy hunting and exposed the possibility that it may have negatively affected population dynamics.  Major collaborators are Jon Jorgenson of Alberta Fish & Wildlife, David Coltman of the University of Alberta, Jack Hogg of the Montana Conservation Science Institute, Fanie Pelletier of the Université de Sherbrooke and Kathreen Ruckstuhl of the University of Calgary.

Evolutionary ecology and population dynamics of Eastern grey kangaroos (Macropus giganteus), Victoria, Australia.  In collaboration with Graeme Coulson of the University of Melbourne, Dave Forsyth of the Victoria Department of Sustainability and the Environment, and Dany Garant of the Université de Sherbrooke.  We have marked over 700 kangaroos in three populations and are examining the determinants of male and female reproductive success, including population density, sex and age structure, body size, genotype, birthdate, parasites and yearly changes in the amount and timing of precipitation.  A key part of this research is the manipulation of reproductive effort through the use of contraceptive implants.

Reproductive success and population dynamics of mountain goats (Oreamnos americanus). Caw Ridge, Alberta. This study began in 1988 and is now led by Steeve Côté of Université Laval. We explore the long-term effects of dominance status, age structure, resource availability, and horn and body size on individual reproductive success and on population dynamics.

Ecology and conservation of Alpine chamois (Rupicapra rupicapra).  In collaboration with the Parco Naturale Alpi Marittime and the local wildlife management agency, we examine the consequences of alternative management regimes (including complete protection) on hunter selectivity, individual development and population dynamics.  This research is based on monitoring marked chamois and on the analysis of horn and body growth of hunter-harvested individuals.

Ecology and conservation of migratory tundra caribou (Rangifer tarandus) in northern Québec and Labrador.  This is a major collaborative effort with Steeve Côté and Jean-Pierre Tremblay at Université Laval and Christian Dussault of the Ministère des Ressources Naturelles et de la Faune du Québec.  Building on a unique long-term monitoring program of caribou with satellite radio collars, we are studying the effects of habitat changes (including climate change and other artificial influences) on the ecology, migration, reproductive success and population dynamics of caribou.

 "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.
