Effects of seed and carabid densities on the weed seed predation service

2017
Farming relies heavily on pesticides in order to maintain/increase crop production, yet, awareness of the adverse effects of pesticides on the environment and on biodiversity has triggered the search for alternative, non-chemical, pest management strategies. In arable systems, weeds remain one of the most challenging management issue.

Consequences of reduced bird densities for seed dispersal

2013
The decline in range and density of frugivorous birds worldwide could have consequences for the functioning of ecosystem processes such as seed dispersal. I endeavoured to determine the effects of bird declines on seed dispersal and assess the current status of dispersal in New Zealand.
