Cattle Grazing Effects on Macroinvertebrates in an Oregon Mountain Stream
Cattle grazing effects on aquatic macroinvertebrates were assessed in a 4-year experiment of a mountain stream in northeastern Oregon. From 1996 through 1999, 10 cow–calf pairs were introduced into 6 experimental units along the stream for 42 days between July and September, and effects on aquatic macroinvertebrates were compared with 3 units in which no grazing occurred. Streambank and geomorp...
متن کاملInvestigating the correlation between vegetation cover, soil elements and plant and soil organic carbon storage in mountain pastures under flooding and grazing (case study: Asadabad Pass, Hamadan)
The extent of rangeland is one of the most important characteristics of organic carbon uptake and storage in soil and plants. The present study investigates the indices of plant diversity and organic carbon storage in mountain pastures under grazing and 10-year enclosure in Asadabad. The rangeland is approximately 100 hectares and its rangelands are in good condition and are in the 2S class in ...
متن کاملSeasonal changes in the digesta-adherent rumen bacterial communities of dairy cattle grazing pasture
The complex microbiota that resides within the rumen is responsible for the break-down of plant fibre. The bacteria that attach to ingested plant matter within the rumen are thought to be responsible for initial fibre degradation. Most studies examining the ecology of this important microbiome only offer a 'snapshot' in time. We monitored the diversity of rumen bacteria in four New Zealand dair...
متن کاملGrazing intensity and soil depth effects on soil properties in alpine meadow pastures of Qilian Mountain in northwest China
In the mountainous rangeland of inland arid regions of Eurasia, seasonal grazing has been important to local communities for production of food, fiber, and for income, for the past thousand years. Recent population increases and other changes have put traditional grazing systems under pressure. However, empirical data describing soil properties or the impact of traditional grazing practice on t...
متن کاملMountain pastures of Qilian Shan : plant communities , grazing impact and degradation status ( Gansu province
Environmental degradation of pasture areas in the Qilian Mountains (Gansu province, NW China) has increased in recent years. Soil erosion and loss of biodiversity caused by overgrazing is widespread. Changes in plant cover, however, have not been analysed so far. The aim of this paper is to identify plant communities and to detect grazing-induced changes in vegetation patterns. Quantitative and...
