the widely known "Fence Effect". Within a year of living in the fenced area the voles had increased by about five times, which is much more than they would in an unfenced area. He then observed that the population experienced a crash, just like the unfenced populations do. Krebs believed this was due to social behaviour among the voles and could be applied to other animals like them. The voles had no place to migrate therefore the final crash seemed to stem from an increase of competition, aggressive behaviour, and decreased resources.

snowshoe hares and their predators in the Yukon. He found that the population size of the snowshoe hares is regulated by predators such as the lynx, coyote, great horned owls and goshawks. 90% of their deaths were found to be due to these predators and almost none because of starvation and disease.

Krebs was interested mostly in smaller mammal ecology and in 1965 conducted an experiment on voles. He fenced in an area of grassland in an
Indiana pasture about the size of a soccer field and observed what happened to the population of voles living inside the fenced area. This was when he founded

Krebs also worked in
British Columbia and Northern Canada for over 40 years to look at cyclic populations of mammals. during this time he was able to transform the field of ecology from a descriptive science to an experimental discipline. For 20 years he studied the 10-year population cycle of

If someone asks me if my work has economic benefit I say absolutely none. And then they ask 'well why are you doing it' and I say that we need to understand the world we live in. It enriches our lives.
