Succession in Natural Communities
... Many ecologists have tried to answer the hard questions about what these terms mean exactly, but few have done as well as J.H. Connell and R.O. Slatyer did in 1977. The idea of succession leading to climax communities was a popular idea in ecology for much of the 20th century. R.H. Whittaker stated ...

One can ascertain the persistence of such populations only by obtaining data that allow the prediction of fu ...

Causes and Consequences of Spatial Heterogeneity

The first, which considers a landscape as a specific area based on human scales, is intuitive: Landscapes are ecological systems that exist at the scale of kilometers and comprise recognizable elements such as forest patches, fields, and he ...

The fact that so much important ecological research can continue to be done without even a nod to the potential for ongoing evolution suggests that there must be at least some truth to that assumption.
