Livestock grazing in the shortgrass steppe of the Intermountain region of British Columbia is predicted to have significant effects on grassland habitats and their associated ground-nesting bird communities. We tested whether grazed and ungrazed sites could be discriminated on the basis of their vegetation communities, whether the abundance of two ground-nesting bird species, Vesper Sparrow (Po...
Highlight: Two tallgrass prairie areas burned annually for 20 (grazed) nnd 48 (un. grazed) years ar different fimeS showed differences in soil chemical and physical properties. Winter, early-spring, and mid-spring burned ungrared plots were generally higher in soil pH, organic ma~fer, and K than late-spring burned or unburned plots. Late-Jpring and winter burning lowered soil N on ungrazed and ...
abstract: advertisements are the most accessible type of authentic materials, and this is one reason why they are used more and more in english teaching classes. for this cause, studies in the field of advertisements are very widespread nowadays. for pun is one aspect which makes advertisements more interesting, it is used more than before in advertisements. use of puns makes an advertisement m...
Activities of transhumance ongoing have been mostly carried out in alpine pastures for centuries in Turkey. These pastures used unconsciously have faced to the danger of extinction. In order to implement improvement plans in the mentioned areas, qualitative and quantitative characteristics of pastures should be determined. This study was conducted in the mowed and grazed pastures in alpine zone...
building on previous studies on intellectual features and learners’ grammar learning, the present study aimed at investigating whether intelligence criterion had any impact on efl learners’ english grammar learning across two intelligence levels. in the current study, the participants were divided into two experimental and control groups by administration of raven i.q. test. this led to the for...
We determined if sequence of ingestion affected use of endophyte-infected tall fescue (TF) when cattle also grazed birdsfoot trefoil (BFT) or alfalfa (ALF). Based on chemical characteristics of TF (alkaloids), BFT (tannins), and ALF (saponins), we hypothesized that cattle first allowed to graze ALF or BFT would subsequently spend more time grazing TF than cattle that first grazed TF followed by...
Wetlands are critical ecosystems for supporting biodiversity and regulating climate. Over the past century, it has been degraded significantly due to both climatic human activities. In Mongolia, livestock grazing drastic impact on this ecosystem. study, we seek understand effects of soil water content (SWC) moisture by contrasting grazed non-grazed area in a wetland north-eastern Mongolia. We f...
in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...
Tall fescue (Festuca arundinacea Schreb.) infected with the endophyte Neotyphodium coenophialum ([Morgan-Jones and Gams] Glenn, Bacon, and Hanlin) causes fescue toxicosis in cattle grazing the forage, but effects of the endophyte were considered to be abated soon after removal of the animals from pastures. Tasco-Forage, a proprietary extract from the brown seaweed Ascophyllum nodosum, is a know...
