Which statement best describes the difference between the theoretical concept of a community and the ways in which communities are delineated in practice? in theory, communities can be defined by physical or biological characteristics, but in practice, these characteristics are difficult to measure and are not used. In theory, a community is defined only by abiotic factors of the area; in practice, communities are delineated by biological attributes as well. In theory, communities consist of ...

ANSWER KEY “The Wolf, the Moose, and the Fir Tree: A Case Study of Trophic Interactions” by Gary M. Fortier Department of Small Animal Science Delaware Valley College Part I – Introduction Experimental manipulations can be quite difficult in systems containing large vertebrates. Consequently, long-term observations and correlational analysis are often used to assess interactions between different trophic levels. The limitations of this approach are well known; strong correlations...
