Vn. Lopatin et Bd. Abaturov, COMPARISON OF POPULATIONS OF HERBIVOROUS MAMMALS WITH DENSITY, TROPHIC, AND DENSITY-TROPHIC DEPENDENT TYPES OF REGULATION, Zurnal obsej biologii, 55(4-5), 1994, pp. 573-582
Mathematical models of population dynamics of herbivorous mammals with
three types of regulations are formalized and generalized. Variation
of some population characteristics under influence of fodder vegetatio
n productivity and population parameters are considered. Regulatory me
chanisms and productivity characteristics of populations (biomass, pro
ductivity, production formation efficiency) are analyzed for different
types of regulation. Populations with mixed density and trophic depen
dent regulation are shown to take intermediate position between those
with density dependent and with trophic dependent regulations. The fir
st type of regulation thus may be considered as more general one, whil
e the two others are its extreme cases. Mechanisms of realization of t
hese regulation types and their examples are considered.
