The travel cost method of deriving demand and value of recreation
does not include fixed costs of recreational durable goods purchases
or allow for supply restrictions on the number of suitable

The concept of ecosystem management requires that management prescriptions account for economic and environmental goals that are measured in non-commensurate units. This study examines the economic and environmental trade-offs associated with planting a riparian buffer in trees to reduce stream temperatures in the Mohawk watershed, Oregon. The detrimental effects of...
This study was conducted to determine the relationships among the
linear type traits of rump angle, rump width, rump length, rear legs
side view, rear legs position, rear legs rear view, tailhead, vulva
angle, mobility, pasterns, foot angle, and toes with reproductive
performance (days open and times bred) in Holstein...
The yellow discoloration in canned oysters, which appeared after several months of storage, has been proven to be due to carotenoid pigments which were contained in the liver of the oyster. It was found after making carbon disulfide extractions of the liver and of the discolored tissue from canned oysters...

Generally, roots of Italian ryegrass fluorescece when exposed to ultraviolet light, while roots of perennial ryegrass do not. Presence of fluorescent seedlings...
