The effects of feeding in different quality rangelands on meat and fatty acids composition Angora goat kids bucks were determined. Twenty male selected from each farm that produces goats the area. There are three separate with previously determined classes (good, medium, low-quality). In farm, among these animals grazed completely rangeland, 7 heads 4-month-old 7-month-old slaughtered. Longissi...

The adoption and adaptation of enclosures in the arid and semi-arid rangelands of sub-Saharan Africa is driven and sustained by a combination of factors. However, reviews indicate that these factors cannot be generalized, as they tend to be case specific. A study was therefore conducted to explore the history and reasons for enclosure establishment in Chepareria, a formerly degraded communal ra...

Biological invasion is a widespread, but poorly understood phenomenon. Elton’s hypothesis, supported by theory, experiment, and anecdotal evidence, suggests that an important determinant of invasion success is resident biodiversity, arguing that high diversity increases the competitive environment of communities and makes them more difficult to invade. Observational studies of plant invasions, ...

Provision of free, universal access to biodiversity information is a practical imperative for the international conservation community — this goal should be accomplished by promotion of the Public Domain and by development of a sustainable Biodiversity Information Commons adapting emergent legal and technical mechanisms to provide a free, secure and persistent environment for access to and use ...

Access to and sharing of data is essential for biodiversity conservation. However, workers from developing nations that harbor rich biodiversity often do not have access to biodiversity information and often are not keen on making what data they have accessible to others. Open access initiatives offer a great opportunity to make the world’s biodiversity information accessible to anyone, at any ...

[1] In 2000–2002, three rangeland and six irrigated sites were instrumented to assess the storage and transit time of chemicals in thick (15 to 50 m) unsaturated zones (UZ) in the High Plains. These processes are likely to influence relations between land use and groundwater quality, yet they have not been documented systematically in the High Plains. Land use and climate were important control...

Cryptosporidium parvum is a fecal borne protozoan parasite that can be carried by and cause gastrointestinal illness in humans, cattle, and wildlife. The illness, cryptosporidiosis, can be fatal to persons with compromised immune systems. At question is the potential for C. parvum in cattle fecal deposits on rangeland watersheds to contaminate surface water. First, C. parvum oocysts must be rel...

Invasive plants reduce the capacity of ecosystems to provide goods and services required by society, alter ecological processes, and can displace desirable species. They can reduce wildlife habitat quality, riparian area integrity, rangeland economic value, and enterprise net returns. The invasion process is regulated by characteristics of the invading plant and the community being invaded. The...

Soil characteristics and functions are critical determinants of rangeland systems and the ecosystem services that they provide. Rangeland soils are extremely diverse, but an emerging understanding is that paradigms developed in more mesic forest ecosystems may not be applicable. Vascular plants, biological soil crusts, and the soil microbial community are the three major functional groups of or...
