Microbiotic crusts are a common and widespread feature of arid and semi-arid landscapes. Their effect on vascular plant success has been discussed controversially. However, only very few field studies have yet tried to experimentally investigate the effect of microbiotic crusts on vascular plant establishment.

In this study we investigate the influence of cyanobacteria dominated microbiotic. Cryptogamic soil crusts are reported to have both positive and negative effects on recruitment and survival of vascular plants. At four sites in SW Montana, Arabis fecunda (Brassicaceae), a rare.

Effects of reproductive mode on demography and life history in Arabis fecunda (Brassicaceae). American Journal of Botany –   Goats have always been considered very useful animals.

Goats success is related to its excellent adaptability to the difficult mountain conditions, extreme weather and low value feed acceptance, versatile habits and high production considering their size. These are some reasons because goats are among the first animals to be domesticated.

In terms of evolution, goats could be separated. Rangeland and pastures comprise about 42% of the total land area of the United States. About three-quarters of all domestic livestock depend upon grazing lands for survival.

Many ranges have had domestic stock grazing for more than years and, as a result, the plant composition has changed greatly from the original ecosystems.

Open Journal of Soil Science Vol No.3, Ma   Arabis fecunda, a herb endemic to some calcareous soils of Montana, United States, can be divided into two ecotypes.

The one "low elevation" group lives near the ground in an arid, warm environment and has thus developed a significantly greater tolerance against drought than the "high elevation" group.

Book Description. Grazing lands represent the largest and most diverse land resource-taking up over half the earth's land surface.

The large area grazing land occupies, its diversity of climates and soils, and the potential to improve its use and productivity all contribute to its importance for sequestering C and mitigating the greenhouse effect and other conditions brought about by climate.

This is because marine oil spills can have a serious economic impact on coastal activities, as well as on those who exploit the resources of the sea. Reclamation of land by irrigation was extensively developed by the Soviet the late s the Soviets reported a total of about 27 million acres (11 million hectares) under irrigation, about one-half of this being in the Central Asian republics.

The Syr Darya and Amu Darya rivers were the principal sources of irrigation water in this area. These rivers discharged into the Aral Sea, and.

Introduction. The gastrointestinal tract of horses provides a target site for many internal parasites species, such as Parascaris equorum, Habronema spp., Gasterophilus spp., and tapeworms. These parasites have the potential to cause serious diseased conditions in horses including diarrhoea, emaciation, colic, anaemia, haemorrhage and death (Mfitilodze and Hutchinson, ; Gawor, ).
