It is shown for binary (1, 0) data that there is a direct relationship between a new measure of predictivity in classification and the Simple Matching Coefficient. This predictivity measure is related to the variance of a cluster in phenetic space an

Three genera of predacious mites in the subfamily Phytoseiinae (Acarina: Phytoseiidae) are known to occur in Canada and Alaska. Chant reviewed the genus Phytoseius Ribaga in Canada, and Chant and Hansell reviewed the genus Amblyseius Berlese in Canad

In the lark bunting, a grassland "sparrow," polygyny occurs. Pleszczynska (1978) demonstrated that certain females must choose between being the secondary female on a prime site or the only mate of a male on an inferior habitat. Here, we examine the

We consider an evolutionary game model in which strategies are transmitted culturally from parents to offspring rather than inherited biologically. Our analysis yields two noteworthy results. First, biocultural games show a greater diversity of dynam

Kelthane MF showed a positive temperature coefficient of toxicity to the two-spotted spider mite, Tetranychus telarius. An increase of about 1.2% mortality occurred for each degree rise in the range from 50-90°F. Pre-treatment of adult, female mites

A spatial analogue of the logistic model is constructed, with sub-populations located on a 10 by 10 grid, with terms representing long lived propagules such as seeds left in the seed bank by plants or eggs left by many insects and other animals, and

There is a great need in taxonomy today to develop an understanding of the methods by which classical taxonomists construct classifications. Of particular interest are the methods by which characters are weighted, that is, placing different emphasis
