Determining trophic niche width: a novel approach using stable isotope analysis [PDF]

open access: yes, 2004
1. Although conceptually robust, it has proven difficult to find practical measures of niche width that are simple to obtain, yet provide an adequate descriptor of the ecological position of the population examined. 2.

Soil nematode responses to fertilization with ammonium nitrate after six years of unfertilized apple orchard

open access: yesSpanish Journal of Agricultural Research, 2014
A nematode community was used as a bioindicator of changes in agroecosystems caused by fertilization. The effect of applying nitrogen (N) fertilizer on a soil nematode community structure was studied in a soil which had not been fertilized for six years ...
