The effects of crowding on mackerel (Scomber scombrus L.) — Physical condition and mortality     

S.J. Lockwood  M.G. Pawson  D.R. Eaton 《Fisheries Research》1983,2(2):129-147

Series of trials in which mackerel (Scomber scombrus L.) were confined in keepnets at different stocking densities are described. From simple confinement trials it was found that 50% of the fish died after 48 h at a stocking density of 30 fish m⁻³, equivalent to 6.5 kg m⁻³. Trials in which fish were held at stocking densities, and for a duration, comparable to those experienced in a “dried up” purse seine prior to “slipping”, showed that up to 90% of “slipped” fish died within 48 h of release. The primary cause of death was probably physical damage, particularly skin loss, caused by abrasion, although there is some evidence that mackerel have a healing process which can accommodate minor skin abrasions. A tagging trial showed a small but significant increase in mortality due to the tagging procedure.  相似文献

Prevalence of Rabies Virus in Foxes Trapped in the Canadian Arctic   总被引：1，自引：1，他引：0       下载免费PDF全文

Brains and salivary glands of 521 trapped arctic foxes (Alopex lagopus) submitted from four different settlement areas in the Northwest Territories were examined for rabies by the standard fluorescent antibody and mouse inoculation tests. Rabies antigen was present in 44 of 201 (21.9%) brains from foxes trapped in the Sachs Harbour area, but submissions from Cambridge Bay (127), Spence Bay (93) and Gjoa Haven (100) were negative. Virus was also present in salivary glands from 43 (97.7%) of these 44 positive foxes.

The arctic fox continues to be the main wildlife reservoir of rabies in the Canadian Arctic and foxes in the prodromal stage of the disease pose a particular threat to the trapper. Preexposure vaccination should always be a consideration in this occupational group.

Survival at extreme altitude: protective effect of increased hemoglobin-oxygen affinity   总被引：3，自引：0，他引：3  

J W Eaton  T D Skelton  E Berger 《Science (New York, N.Y.)》1974,183(126):743-744

Decreased hemoglobin-oxygen affinity is thought to be of adaptive value to humans and nonindigenous animals at high altitude. To test this, hemoglobin-oxygen affinity was modified by carbamoylation of hemoglobin in rats. Exposure of control (low oxygen affinity) and experimental (high oxygen affinity) animals to a pressure equivalent to high altitude revealed that increased, rather than decreased, hemoglobin-oxygen affinity will permit survival at greatly reduced environmental oxygen pressures.  相似文献   

Carbon flow in four lake ecosystems: a structural approach     

Richey JE  Wissmar RC  Devol AH  Likens GE  Eaton JS  Wetzel RG  Odum WE  Johnson NM  Loucks OL  Prentki RT  Rich PH 《Science (New York, N.Y.)》1978,202(4373):1183-1186

Direct and indirect carbon fluxes in lakes Marion (British Columbia), Findley (Washington), Wingra (Wisconsin), and Mirror (New Hampshire) are compared, using budgets and input-output analysis. Overall differences in carbon flow between the lakes are shown with cycling indices of .031, .108, .572, and .661, respectively. The results suggest that lake ecosystems may be considered unique aggregatins of similar components.  相似文献

Erythrocyte metabolism: interaction with oxygen transport   总被引：4，自引：0，他引：4

Studies of the interactions between the metabolism and the function of the red cell have shown the importance of the red cell's metabolism in contributing to the maintenance of adequate oxygen delivery. Some of the phosphorylated intermediates of glycolysis, especially DPG, are now known to reduce the affinity of hemoglobin for oxygen. Current evidence indicates that this phenomenon is due to the effects of the binding of DPG to the , beta-chains of deoxyhemoglobin. It appears that increases in red cell concentrations of DPG commonly occur during hypoxia, and that these increases (as well as normal physiological variation) significantly enhance oxygen transport. Artificial manipulation of erythrocyte metabolism may soon prove to be of great clinical usefulness in the treatment of a great variety of disorders which limit oxygen transport.  相似文献
