Diversity and conservation of domestic and wild canids
We study the evolution of wild and domestic canids, and their interactions on each other.
There are a number of ongoing studies focusing on different aspects of the evolution of canids using ecological genetics, genomics and ancient DNA:
The central coast of British Columbia is the largest intact coastal temperate rainforest in the world. The rugged landscape, comprised of innumerable islands separated by open ocean lies on the western side of the Coastal Mountain Range. Deep fjords punctuate the coastline. Its remote nature has protected it from the large-scale, industrial, clearcut logging that has severely altered the environment in adjacent southeast Alaska and Washington state. Because the “Great Bear Rainforest” is largely undeveloped and sparsely populated, it is supposed that this archipelago landscape still harbors large carnivores and their natural prey base in historical abundances. However, due to the inaccessibility of this habitat, basic parameters such as the distribution and density of large mammals, including wolves and their prey are unknown. With the help of the local Heiltsuk First Nations people, we explore this area by boat and collect data permitting an estimation of these fundamental parameters.
The island ecosystem may impose unique constraints on the activities of predator and prey. Based on data from adjacent areas, we believe that many of the islands are too small to support a sufficient number of deer to maintain a persistent population of wolves. Moreover, wolves have been observed swimming among islands, likely searching for areas where vulnerable prey has not been exhausted. The time lag between population recovery by deer and the island’s subsequent re-colonization by wolves defines a unique predator-prey system that has fundamentally different dynamics than terrestrial ecosystems. Classic survey techniques cannot easily be used to study patterns of abundance and movements among islands. Consequently, we utilize new non-invasive approaches involving systematic collection of feces across the region multiple times each year. Fecal typing has been shown to be a feasible and accurate method for monitoring activity of canids.
The coastal habitat, previously protected by ruggedness, is now being targeted by logging companies as the resources in the other areas are being exhausted. By comparing the ecological data we collect in this pristine forest with similar data collected previously in coastal southeast Alaska (which has been heavily impacted by logging and hunting), we will be able to assess potential impacts of logging on predator-prey dynamics.
