Relationship among Grazing Management, Growing Degree-Days, and Morphological Development for Native Grasses on the Northern Great Plains

Determining suitable time for exploitation/ grazing of rangeland plants using growing degree days (GDD) model

One of the key principles in rangeland management is determination of suitable times for exploitation and grazing of rangeland plants in summer and winter pasturelands. This determination of time not only prevents degradation of plant species, but also leads to optimal usage of plant yield. Multiple factors affect plant phenology among which temperature regime has the highest effect on plant de...

Effect of supplemental ground flaxseed fed to beef cattle grazing summer native range on the northern Great Plains.

Two experiments were conducted simultaneously to evaluate the effects of supplemental ground flaxseed on site and extent of digestion and growth performance in beef cattle grazing summer native range. Six Angus heifers (initial BW 367 +/- 8.0 kg) fitted with ruminal and duodenal cannulas were used in Exp. 1, and 18 Angus cross steers (initial BW 368 +/- 4.6 kg) were used in Exp. 2. Cattle from ...

Interactive Effects of Drought and Grazing on Northern Great Plains Rangelands

Drought is common in rangeland environments and an understanding of its impacts on the structure and function of rangeland ecosystems is paramount for developing effective management strategies. This research was the second of a series of studies investigating the impacts of varying seasonal droughts on northern Great Plains rangelands. Research was conducted on native rangeland during the 1998...

the impact of morphological awareness on the vocabulary development of the iranian efl students

this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
