Logistic growth equations are derived from a thermodynamic theory of aquatic ecosystems. The equations include the effects of temperature, light and excretion. Inst. of Geography and Geoecology, Acad. of Sci. of the G.D.R., Berlin, DRG. (msg) 83:3550 Stebbins, G.L., 1982. Perspectives in evolutionary theory. Evolution, 36(6): 1109-1118. The synthetic theory of evolution as developed 3 or 4 decades ago need not be cast aside. It is however the case that the vast time scale differences in paleontological and genetic observations result in very different meanings applied to such words as 'sudden' or 'gradual,' 'continuous' or 'punctuated.' The conclusion here is that microevolutionary processes are conceived best as gradual; but over geological time scales, differential survival of species presents a picture best described as punctuated equilibrium.

The relationship between environmental stability and community diversity is reviewed; both evolutionary and ecological mechanisms are considered. Environmental stability/instability is seen as a troublesome concept with no clear rules and insufficient data for evaluation of hypotheses. Integration of ecological effects with both evolutionary mechanisms and spatial instability (heterogeneity) is essential to further understanding. Aquatic Res.

Ecol. Model., 17(2):53-180; 12 papers. Twelve of the 21 papers presented in 1 symposium section are included. These papers reflect the modern trend of returning to simple models based on basic principles. Particular approaches include stochastic theory, nonlinear irreversible thermodynamics, generalized Gibbs relation for entropy change, cybernetic control theoretic methods, multiobjective optimization, correlation analysis, and an extension of the Lotka-Volterra equations. Several papers attempt to derive 'ecological relations from first principles' and from physical, chemical and biological constraints. Systems dealt with include the Black Sea, lakes, reservoirs, aerobic biological wastewater treatment plants, sediments, and phytoand zooplankton growth. (mjj)

Published data on ingestion-limited growth are consistent with Blackman kinetics. If ingestion limits growth rate there is a linear relationship between growth and ingestion from starvation to satiation; if growth is limited by some other factor, there is no increase in growth rate with increasing ingestion rate.
