Snowshoe Hares (p. 46) 
W.B. Grange’s The Way to Game 
Abundance (New York: Charles 
Scribner’s Sons, 1949) is a thorough 
treatment of the subject of game man- 
agement, emphasizing the need to 
match control strategies with an ani- 
mal’s life patterns and environmental 
interactions. Part of the section on popu- 
lation cycles is devoted to the snowshoe 
hare, outlining the mechanism and 
simultaneity of its cycle, the changes in 
its habits and psychology, and the na- 
ture of predation. L.B. Keith’s Wild- 
life's Ten Year Cycle (Madison: Univer- 
sity of Wisconsin Press, 1963) presents 
information on the ten-year cycle, a phe- 
nomenon of long-term fluctuations in 
northern wildlife populations, and sys- 
tematically reviews what is known about 
these fluctuations — their periodicity, 
regularity, amplitude, and synchrony; 
relationship to other population phe- 
nomena; and postulated causes. Exten- 
sive data on the snowshoe hare, dating 
from 1849, are analyzed and inter- 
preted. G.E. Hutchinson’s An Introduc- 
tion to Population Ecology (New Ha- 
ven: Yale University Press, 1978) is a 
comprehensive, readable introduction to 
the interrelationships in nature that de- 
termine ecological balance and explain 
behavior. Although the author uses 
mathematics to explain his subject, it is 
kept to a minimum and is, for the most 
part, simple. Stability and Complexity 
in Model Ecosystems, edited by R. May 
(Princeton: Princeton University Press, 
1974), illustrates various hypothesized 
relationships in nature through the use 
of ecosystem models. The book is clearly 
written but it demands a knowledge of 
statistics, matrix algebra, and differen- 
tial calculus. J. P. Finerty’s The Popula- 
tion Ecology of Cycles in Small 
Mammals (New Haven: Yale Univer- 
sity Press, 1980) takes a look at all the 
different hypotheses of animal cycles, 
particularly the well-documented snow- 
shoe hare cycle. The first section is a 
natural history of lemming, vole, and 
hare cycles; the book later involves 
fairly high-level mathematics. D.H. Jan-
