Effect of Sample Materials on the AFM Tip-Based Dynamic Ploughing Process
, 2011 To study the effect of different sample materials on the nano dynamic ploughing process in the AFM tapping mode, the spring-oscillator model is employed to simulate the vibrating AFM tip to deform the sample surface.

A root–soil association index reveals life‐history strategies of arbuscular mycorrhizal fungi
New Phytologist, EarlyView.Phylogenetic tree of Glomeromycota, including all studied virtual taxa, based on the small subunit region. The bar plot in the external part of the phylogeny depicts the log‐transformed arbuscular mycorrhizal root–soil association index, with values > 0 indicating rhizophilic lifestyle, < 0 edaphophilic lifestyle, and close to 0 no preference.

Ploughing behaviour of the babirusa (Babyrousa babyrussa) suggests a scent marking function
, 1996 A unique form of behaviour, 'ploughing behaviour', was studied in experiments carried out on 13 babirusa, three adult males, two sub-adult males, five adult females and three sub-adult females. Ploughingbehaviour was observed when individual animals were

Restoration Ecology, EarlyView.Abstract Introduction Natural recovery of disturbed marine ecosystems can take years, mainly because long‐lived, functionally important species are lost. To regain ecosystem services, the focus of estuarine restoration is shifting from biodiversity metrics to functional restoration.

Water and Environment Journal, EarlyView.Tracer testing assessed hydraulics and nitrate removal in three full‐scale agricultural drainage treatment wetlands over 3.5 years (three tests). The first test showed rapid, short‐circuited flow and low residence time. After modifying the collection system, the second test increased residence time from 1 to 7 days.
