hybrid plants that were sterile. One parent genotype (P₁)
was from P. I. 234-906, introduced from Switzerland and the other
(P₉) was an introduction from Turkey, P. I. 174-209. P₁

The present work is an attempt to correlate information collected in the northern part of Chile with the anchoveta distribution and its fluctuation. This information was collected over a three year period (November 1967 to November 1970) by the Instituto de Fomento Pesquero, Chile (IFOP). The first and second part...
The ecosystem services provided by our forest resources and woodlands are multiple and diverse on all spatial and temporal levels, and include provision, regulating, cultural, and supporting services (Hanson, et al. WRI, 2008). Human activities are proximate and direct drivers of deforestation and forest degradation. In the Latin American region,...
Dryland winter wheat in eastern Oregon is usually subjected to
water stress several times during the growing period. Moreover, the
last three months of growth period depend strongly on the available
soil water. The fertility level, stage of growth, availability of
soil water and climatic conditions all interact to determine...
Posting advisory speed signs at sharp horizontal curve sites is a practice well established in the United States. The purpose of these signs is to provide the driving public with a safe speed to negotiate such curves; however, the link between these signs and safety has not yet been clearly...
Posting advisory speed signs at sharp horizontal curve locations is a common practice in the U.S. These signs recommend drivers safe speeds to negotiate such curves. Literature indicates that adherence to advisory speeds is, in general, poor. Moreover, limited research is available that quantifies safety implications of these signs. This...
Three case studies were included in a study on fishing vessels, most of which use trawl gear in demersal
fisheries. The case studies include the French Bay of Biscay bottom-trawlers, the English beam trawlers
fishing in the English Channel, Celtic Sea and North Sea, and the Basque trawlers fishing in...
This work reports on how resource rent is distributed among owners of exclusive fishing grounds in the spiny lobster (Panulirus argus) fishery of Punta Allen, Mexico. This MSC certified small-scale fishery is co-managed through Territorial User Rights. Members of the local fishing cooperative, have exclusive access to individual fishing grounds....
This work reports on the implications of an extreme climatic event among owners of fishing grounds in the spiny lobster (Panulirus argus) fishery of Punta Allen, Mexico. This MSC certified small-scale fishery is co-managed through Territorial User Rights. Members of the fishing cooperative, have exclusive access to individual fishing grounds...
The study presents a bioeconomic analysis of artificial shelter performance in a fishery targeting a spiny lobster meta-population, with spatially allocated, individual exclusive benthic property rights for shelter introduction and harvest of species. Insights into fishers’ short-run decisions and fishing strategies are also provided. Spatiotemporal bioeconomic performance of shelters located...
