The gene coding for the major capsid protein (VP60) from rabbit haemorrhagic disease virus was expressed in Saccharomyces cerevisiae under the phosphoglycerate kinase promoter. The recombinant VP60 produced in yeast was antigenically similar to the viral polypeptide as determined with a polyclonal serum. Electron microscopic observation of the recombinant yeast-derived antigen revealed the pres...

Abstract: Classic resource competition theory typically treats resource supply rates as independent; however, nutrient supplies can be affected by plants indirectly, with important consequences for model predictions. We demonstrate this general phenomenon by using a model in which competition for nitrogen is mediated by soil moisture, with competitive outcomes including coexistence and multiple...

Rabbit reticulocytes at elevated temperatures, such as 45”, rapidly show a decrease in the rate of hemoglobin synthesis to one-third to one-tenth of the rate at 3’7”. This lower rate, which becomes irreversible after a few minutes, remains linear for up to 75 min. The soluble protein made at 45” is hemoglobin. Synthesis occurs on small polysomes carrying only two or three ribosomes, but actidio...

General properties of the Canadian English vowel space are derived from an experimentalacoustic study of vowel production underway in Winnipeg, Manitoba. Comparing the preliminary Winnipeg results with similar data from General American English confirm previously described generalizations for Canadian English: the merger of low-back vowels, the relative retraction of /æ/ and the relative advanc...

In the preceding paper of this series (1) it was reported that the amount of specific antibody precipitable by the capsular polysaccharide is related to the mouse protective value of Type I antipneumococcus serum only under certain well defined conditions. Thus with Type I antipneumococcus rabbit serum there was a direct proportionality between the two determined values. The protective ratio fo...

In 2010 a new Lagovirus related to rabbit haemorrhagic disease virus (RHDV) emerged in France and has since rapidly spread throughout domestic and wild rabbit populations of several European countries. The new virus, termed RHDV2, exhibits distinctive genetic, antigenic and pathogenic features. Notably, RHDV2 kills rabbits previously vaccinated with RHDV vaccines. Here we report for the first t...

We consider example-critiquing systems that help people search for their most preferred item in a large catalog. We first analyze how such systems can help users in the framework of three existing example-critiquing approaches (RABBIT, Incremental-critiquing and ATA). Afterwards we consider the use of several novel types of explicit passive analysis to guide the users in their search when their...

In 1997, a group of pastoral farmers, frustrated by governmental and official responses to their problems of rabbit control, introduced and spread the rabbit haemorrhagic disease virus in a clandestine operation that succeeded in distributing infection over a large area of the South Island before the disease was detected by government officials. The government concluded that eradication was not...

Species respond to climate change in two dominant ways: range shifts in latitude or elevation and phenological shifts of life-history events. Range shifts are widely viewed as the principal mechanism for thermal niche tracking, and phenological shifts in birds and other consumers are widely understood as the principal mechanism for tracking temporal peaks in biotic resources. However, phenologi...

An experimental analysis of the factors responsible for the observed differences in the course of virus-induced papillomas of the rabbit has shown that some are referable to the virus, others to the cells, and yet others to host influences. The interplay of these factors affords enlightening illustration of the nature of the cell-virus relationship in virus-induced tumors. Retrogression of the ...
