Following evolutionary theory and an agriculture model, ecosystem research has stressed bottom-up dynamics, implying that top wild predators are epiphenomenal effects of more basic causes. As such, they are assumed expendable. A more modern co-evolutionary and wilderness approach--trophic cascades--instead suggests that top predators, whose…

Abstract is of a pivotal genre in scientific communication, assisting not only highly selective readers with judgment of the pertinent articles but also researchers in disseminating new knowledge and intellectual discoveries. Difficult yet challenging, however, is the task of writing effective abstracts particularly among non-English speaking…

Incubation studies are traditionally used in soil microbiology laboratory classes to demonstrate microbial respiration and N mineralization-immobilization processes. Sometimes these exercises are done to calculate a N balance in N fertilizer-amended soils. However, examining microbial responses to environmental perturbations would appeal to soil…

Purpose: This paper aims to diffuse the concept of a multi-lateral learning process as a means to promote experimental didactics and research (and the cross-fertilization between these two activities) in the field of design of sustainable product-service systems (PSSs) and to consider the university campus as the locus for the design,…

In response to environmental degradation, the Lesotho government, in collaboration with the Danish government, introduced an Environmental Education Support Project in schools in 2001. In order to optimise the achievement of the project goals the, Monitoring and Research Team was established to formatively evaluate the project as it unfolded. The…
