We measured the effects of wet meadow vegetation on the shear strength of (1) river banks cutting into wet meadow floodplains located at the outside of river meanders, and (2) point bars forming the inside bank of meanders.

Two hybrids CW consist of two series of VSSF that in one line up-up or down-down flow and in other line up-down or down-up flow were carried out. Average influent concentrations and removal efficiency for COD, TN, TP and TOC in each hybrid CW are shown in Table Size: KB.

We used a randomized block design, with meadow voles maintained at three density levels (low, medium, high; three replicates of each) in field enclosures of 17 by: In a six‐year experiment, meadow voles (Microtus pennsylvanicus) reduced plant standing crop between 30% and 72%, well within the range of ungulate effects.

Moreover, meadow voles reduced their available forage species by changing the plant community composition: four grass species and a legume upon which they foraged declined sharply in cover and/or number of individuals, five forbs avoided by voles increased, and two forbs Cited by: Effects of 11 years (–) of nutrient enrichment (fertilizer or sludge) on microbial metabolic activity in soil samples collected from contrasting types of old-field communities were studied during September Cited by: In book: Proceedings of the Environmental Research and Development (R&D) Technical Workshop, Publisher: Naval Ocean Systems Center, Editors: Johnston RK, Wilkins EF, pp Cite this.

Institute of Grassland and Environmental Research, North Wyke, Okehampton EX20 2SB, UK Summary 1. The enhancement of biodiversity in meadow grassland, an environmental aim of European agricultural policy, requires definition of appropriate management regimes and the rate at which they enhance biodiversity and change ecosystem by:   Context.

A puzzling aspect of microtine population fluctuations is the damping out or collapsing of cycles over the last three decades, particularly in northern Europe. Occasional population fluctuations of Microtus may also have been damped out in temperate and boreal forests of the Pacific North-west of North America.

One cause might be the presence of cattle (Bos taurus) grazing in forest Cited by: 2. exist for MG3 and related grassland types suggests there is no significant effect of either different timings and or frequencies of nutrient inputs on floristic diversity.

Occasional liming to maintain a pH of around 6 appears consistent with maintaining vegetation quality on MG3 hay meadow with a past history of lime application.

Introduction. Upland meadow grassland plant communities associated with traditional agricultural management regimes are rare examples of diverse plant communities (Cooch & Rodwell ) found on some of the Pennine Dales in northern England (Ministry of Agriculture, Fisheries & Food ).Elsewhere they usually occur as isolated examples in pastoral landscapes dominated by Cited by: Abstract: 【Objective】The objective of this study is to reveal the effects of grazing intensity on the community structure and diversity of different soil fauna in alpine meadow ecosystems.【Method】The investigations were conducted on the soil faunal communities and soil environment of alpine meadows under different grazing intensities (light grazing, LG, 15 sheep/hm 2; medium grazing.
