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.

Enhanced diamond nucleation density utilising seeding

Diamond and Related Materials, 1998
This paper reports on a new technique for surface pre-treatment of silicon and other substrate materials to enhance diamond nucleation before diamond deposition. Polycrystalline diamond particles (ballas or cauliflower diamond particles) are grown in a CVD environment under hydrocarbon concentrations of 8-15%.

Density‐dependent germination and the role of seed leachate

Australian Journal of Ecology, 1998
Abstract While density dependence is a central issue in much of plant ecology, it is often overlooked during the crucial seed germination period of the plant life‐cycle. Here, patterns of germination in relation to initial seed density for 12 phylogenetically‐diverse perennial plant species are described from laboratory experiments. When each of the 12
