Population-level Responses to Nutrient Heterogeneity and Density by Abutilon Theophrasti (Malvaceae): An Experimental Neigborhood Approach
Download1998-01-01
An experimental approach was used to examine the effects of spatial nutrient heterogeneity and planting density on the sizes of plants within populations of Abutilon theophrasti. Planting locations were generated using random numbers and replicated among populations growing on two different...

Prevalence and predictability of handling effects on plants in field studies: Results from field experiments and a meta-analysis
Download2003-01-01
Brown, M., Hik, D.S., Weir, J., Dabros, A., Cahill, J.F.
Various effects on plant growth associated with handling or touching plants are well documented from greenhouse and laboratory studies, but are generally unknown or ignored under field conditions. We examined the prevalence of the effects of handling, at levels typical of many ecological...

We examined whether the intense root competition in a rough fescue grassland plant community in central Alberta, Canada, was important in structuring plant species diversity or community composition. We measured competition intensity across gradients of species richness, evenness, and community...

Wolf Reproduction in Response to Caribou Migration and Industrial Development on the Central Barrens of Mainland Canada
Download2008
Cluff, H.D., Frame, P.F., Hik, D.S.
Reproductive success of mammals is greatly influenced by food availability. Where wolves (Canis lupus) prey on migratory barren-ground caribou (Rangifer tarandus), caribou migration patterns strongly influence food availability for wolves. However, industrial development in formerly undeveloped...
