Wild herbivore populations are declining in many African savannas, a result of replacement by livestock (mainly cattle) and the loss of large plant-eaters, or megaherbivores, such as elephants.Althoug...
The element contents in the rat tissues reflected the risk element contents in the contaminated soils. Bioaccessibility and bioavailability of the risk elements decreased in the order Cd > As >...
Previous studies have suggested grazing may alter nitrogen (N) cycling of grasslands by accelerating or decelerating soil net N mineralization. The important mechanisms controlling these fluxes remain...
Spatial heterogeneities of vegetation and soil can strongly affect ecological functions of ecosystems, particularly for arid and semi-arid ecosystems where vegetation has a patchy distribution and liv...
Global warming, increasing CO2 concentration, and environmental disturbances affect grassland communities throughout the world. Here, we report on variations in the C3/C4 pattern of Inner Mongolian gr...
Water is one of the key limiting factors for the survival and growth of plant species in arid and semi-arid steppe regions. Different plant functional groups (PFGs) based on life-forms differ in their...
Changes in the carbon (C) stock of grassland soil in response to land use change will increase atmospheric CO2, and consequently affect the climate. In this study we investigated the effects of land u...
Pig slurry is a good soil amendment not only because of its high organic matter content, but also because of its ability to provide various nutrients. The objective of this study was to estimate the i...
The aim of this paper was to evaluate winterhardiness of different cultivars of Lolium perenne L. in pasture and meadow swards on peat-muck soil. The studies were carried out over 1996-2000 in two par...
In the year 2006 we investigated mechanical compaction of soil on the mountain pasture (altitude 920 m). Penetration resistance was researched on the compacted places, by cattle hoofs (breed Charolais...
The present study was carried out to investigate the serum minerals profile in buffaloes (Bubalus bubalis) suffering from parturient haemoglobinuria (PHU) along with minerals profile of soils and fodd...
Human-induced soil salinity is becoming a major threat to agriculture across the world. This salinisation occurs in both irrigated and rain-fed agricultural zones with the highest proportions in the a...
