Some Representational and Ecological Aspects of Evolvability

In this brief position paper I highlight a number of issues relevant to the evolvability of arti cial life systems. These issues became apparent over the course of my doctoral research which involved studying the evolutionary dynamics of a Tierra-like system (Taylor 1999a). The rst two issues (multifunctional phenotypic components and semantic closure) relate to the representation and function ...

Aquatic Invertebrates of Prairie Wetlands: Community Composition, Ecological Roles, and Impacts of Agriculture

The southern portions of Manitoba, Saskatchewan, and Alberta are covered with millions of small water-filled depressions called prairie potholes. These wetlands provide habitat for a diverse array of aquatic invertebrates, which provide an important food resource for the abundant fauna that use these wetlands. Other functions and values of the aquatic invertebrates are not as well known. More i...
