Trade-Off-Invariant Rules For Evolutionarily Stable Life Histories, Eric Charnov May 1997

Trade-Off-Invariant Rules For Evolutionarily Stable Life Histories, Eric Charnov

Biology Faculty & Staff Publications

Optimization models have been widely and succesfully used in evolutionary ecology to predict the attributes of organisms. Most such models maximize darwinian fitness in the face of trade-offs and constraints; the numerical results usually depend on the exact form of the trade-offs or constraints. But not always : for example, earlier work predicted that the optimal range in offspring size ought to show a -1 scaling with small litter size, independent of most details of the underlying offspring-survival/offspring-size trade-off relation. Here I report that in non-growing (stationary) age-structured populations, three major life-history attributes (age at first breeding, size of an …


Stream Organic Matter Budgets, J.R Webster, Judy L. Meyer Jan 1997

Stream Organic Matter Budgets, J.R Webster, Judy L. Meyer

Long Term Ecological Research Network

This analysis of organic matter dynamics in streams has 3 objectives: 1) to explore the relationships between physical characteristics of streams and their watersheds (climate, geomorphology) and steam organic matter dynamics using data from a broad geographic area; 2) to compare steam organic matter dynamics in a diverse array of steams in order to suggest determinants of observed patterns; and 3) to reveal deficiencies in currently available data on organic matter dynamics in steams. Streams were included in this analysis not to represent the global diversity of stream types but because organic matter data were available. In the introductory chapter …
