Measurement of the aboveground biomass of some rangeland species using a digital nondestructive technique
Plant biomass is usually assumed to be positively correlated with canopy cover. Measurements of
canopy cover can now be easily and precisely made through image processing of high-resolution
digital photography. This study ...
Role of GPS in monitoring livestock migration
Satellite-based technique of global positioning systems (GPS) is useful for tracking long-distance livestock movement across the grazing routes md to study the specific needs of livestock herders. There are two kinds of ...
Grasslands in 'Old World' and 'New World' Mediterranean-climate zones: past trends, current status and future research priorities
Despite their ecological, economic and social importance,
grasslands in areas with Mediterranean climates
continue to receive limited scientific, political and
media attention. The main objectives of this review
are to ...
Financial incentives: Possible options for sustainable rangeland management?
Large-scale mismanagement of natural resources emanating from lack of appropriate policies and reg- ulatory framework is arguably one of the reasons that led to resource degradation and poor livelihoods in many countries ...
Effect of protection on plant community dynamics in the Mediterranean arid zone of southern Tunisia: a case study from Bou Hedma national park
Ecosystems protected from heavy grazing impacts, such as national parks and refuges, are generally considered to sustain higher plant species diversity and better ecosystem composition and structure compared to heavily ...
Reliability of Yield Mapping System for Estimating Perennial Ryegrass Seed Yield
Seed yield is an important factor to any farmer. Most farmers recognize that yield will vary within a field due to many factors, but they are unaware of the actual magnitude of the yield variability. Yield mapping is a ...
Direct seeding of Salsola vermiculata for rehabilitation of degraded arid and semi-arid rangelands
Proper soil preparation provides the basis for good seed
germination and establishment of steppe vegetation in
the arid and semi-arid areas of West Asia and North
Africa. Salsola vermiculata is a key shrub species of ...
The vulnerability of native rangeland plant species to global climate change in the West Asia and North African regions
This study aimed to evaluate the impact of climate change on the geographical
distribution of selected native species from two areas from West Asia and North Africa.
Three species representing two genera were selected for ...
Intake pattern and nutrient supply of lactating sheep selecting dried forage from woody plants and straw offered in binary or multiple choice
This study investigated whether offering either binary or multiple choice among low quality
forages has an effect on intake and feeding behaviour compared to no-choice situations
where only one single low-quality forage ...
Assessing the risk of flooding in Central Tunisia
Digital elevation models (DEM) can be used to derive a wealth of information about land surface morphology. When analyzed using GIS information about stream channels and watersheds it can determine the flow of water over ...
