Having 15,5 mill. sheep (1978) Spain is one of the important sheep breeding countries in the Mediterranean. The sheep are distributed all over the central provinces in Spain, and the overwhelming part of the flocks (95%) is sedentary. The main
economic aim is the production of mutton (mainly slaughterlambs) (76% of the returns on the Spanish average) and milk (20% of the returns) whereas woll has a share of only 4%. The different forms of sheep raising are described. They all have in common
that the sheep are tended by shep herds. The number of ther herdsmen is estimated at 52.000 in total Spain. Their life is extremely hard and their social prestige rather low.
Sheep, coffee prices, and ceremonial exchange in Papua New Guinea
. The case study examined here is the diffusion of sheep raising in the highlands of Papua New Guinea. Inadequate financial returns hinder diffusion as does the relative value of sheep in traditional ceremonial exchanges. Income from sale of coffee beans
affects the volume of ceremonial exchanges and hence the demand for sheep.
Population dynamics and horn growth characteristics of Dall Sheep (Ovis dalli) and their redevance to management in Northern ecology and resource management. Memorial essays honouring Don Gill.
The AA. analyse the landscape changes that were induced by the following increase of sheep numbers and the underlying socio-economic and biophysical driving forces in an insular semi-arid locality of Western Lesvos, Greece. Thirty-four sheep farmers
Frequency of debris flows on the Sheep Mountain fan, Kluane Lake, Yukon Territory
Etude de la fréquence des coulées de débris sur le cône de Sheep Mountain , dans la région du Lac Kluane. Les observations dendrochronologiques indiquent qu'il n'y a pas eu de coulées majeures dans le canyon encaissé au cours du dernier siècle
Dynamic model of sheep productivity, describing the impact of environmental factors on main processes of vitability (basal metabolism, calorigenic activities, thermoregulation, grazing, growth) is offered. On the basis of this model it is possible
to work out nex new methods of estimation and prognosis of impact of weather conditions (unfavourable especially) on regime of sheep grazing and productivity of sheep in summer period. - (Ed.).
Age of Sheep Creek tephra (Pleistocene) in Central Alaska from thermoluminescence dating of bracketing loess
The age of the Sheep Creek tephra (SCt), a widespread marker ash bed in eastern Alaska and western Yukon Territory, has been ambiguous and controversial. The AA. have obtained 3 reliable thermoluminescence age estimates from bracketing loess near
Moderate sheep grazing in semiarid shrubland alters small-scale soil surface structure and patch properties
The AA. investigated whether long-term moderate livestock grazing by sheep (ca. 10 animal unit days/ha) in a semiarid shrubland with a long-term average annual rainfall of 200 mm causes changes in soil surface structure and dimensions of shrub
Traditional land use, which depended on a complex social organization and abundant cheap labor, was based on summer sheep grazing and cereal cultivation. After 1950, transhumance disappeared, cattle replace sheep, and cultivated slopes were
Whereas sheep movements in the study area are largely determined by the decisions of shepherds, cattle movement is determined by climatic factors, herbage availability and anatomical contrasts. Access to short tender grass enables sheep to obtain
