The liver lipid fatty acid profiles of seven Indian Ocean shark species     

Bruce Davidson  Geremy Cliff 《Fish physiology and biochemistry》2002,26(2):171-175

We have assessed the fatty acid profiles of the livers from seven shark species (Carcharias taurus (raggedtooth/grey nurse), Carcharhinus limbatus (blacktip), Carcharhinus obscurus (dusky), Carcharhinus leucas (Zambezi/bull), Sphyrna lewini (scalloped hammerhead), Carcharhinus brevipinna (spinner), and Galeocerdo cuvieri (tiger)) found off the east coast of South Africa. While there was generally little variation between the species, Carcharias taurus showed fatty acid profiles that would be most favourable in human nutrition, in that it showed both low saturated (SFA) (37.1%) and high polyunsaturated fatty acid (PUFA) (26.6%) levels. However, all species showed profiles rich in PUFA, thus utilising the liver oil from sharks caught as part of the bycatch when fishing for teleost species would avoid unnecessary wastage of a potentially valuable resource. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

Some effects of off-road vehicles and sheep grazing on lizard populations in the mojave desert     

Stephen D. Busack  R.Bruce Bury 《Biological conservation》1974,6(3):179-183

The effects of two environmentally disruptive activities were determined using the numbers and biomass of lizards. Sheep grazing reduces ground cover necessary for some lizard species. The use of vehicles on the desert also eliminates vegetation and adversely affects lizard populations.  相似文献

Modelling the microbial breakdown of pesticides in soil using a parameter estimation technique     

Jos P. M. Vink  Peter Nrtersheuser  Otto Richter  Bernd Diekkrüger  Klaas P. Groen 《Pest management science》1994,40(4):285-292

Results of field measurements and laboratory experiments were used to simulate the behaviour of 1,3-dichloropropene (1,3-D) in a loamy sand soil. Microbial activity was described using pre-set conditions to compute transformation rates as dependent on compound concentrations and temperature. These kinetics could only be analysed using non-linear transformation rates. To link the development of microbial populations and the consumption of the compound over time, an iterative technique was used to estimate the necessary parameters.  相似文献   

Plants as de-worming agents of livestock in the Nordic countries: historical perspective, popular beliefs and prospects for the future.

Preparations derived from plants were the original therapeutic interventions used by man to control diseases (including parasites), both within humans and livestock. Development of herbal products depended upon local botanical flora with the result that different remedies tended to develop in different parts of the world. Nevertheless, in some instances, the same or related plants were used over wide geographic regions, which also was the result of communication and/or the importation of plant material of high repute. Thus, the Nordic countries have an ancient, rich and diverse history of plant derived anthelmintic medications for human and animal use. Although some of the more commonly used herbal de-wormers were derived from imported plants, or their products, many are from endemic plants or those that thrive in the Scandinavian environment. With the advent of the modern chemotherapeutic era, and the discovery, development and marketing of a seemingly unlimited variety of highly efficacious, safe synthetic chemicals with very wide spectra of activities, herbal remedies virtually disappeared from the consciousness--at least in the Western world. This attitude is now rapidly changing. There is a widespread resurgence in natural product medication, driven by major threats posed by multi-resistant pest, or disease, organisms and the diminishing public perceptions that synthetic chemicals are the panacea to health and disease control. This review attempts to provide a comprehensive account of the depth of historical Nordic information available on herbal de-wormers, with emphasis on livestock and to provide some insights on potentially rewarding areas of "re-discovery" and scientific evaluation in this field.  相似文献
