TLDR
Mechanical analysis, moisture equivalent, loss on ignition, and acidity values of the soils of various communities show differences related primarily to the presence or absence of erosion and deposition phenomena.Abstract:
1. The plant communities lying above the influence of the ground water table on coarse sandy terraces in the townships of Wallingford and North Haven, Connecticut, are mainly stages in three subseres which probably lead up to a xerophytic oak edaphic climax. 2. The subseres are developing on: ridges of wind-deposited sand, superimposed on a grassland type of soil profile; level areas with a truncated soil profile, lacking an A horizon; level areas with soil profile intact. 3. Differentiation of initial habitats resulted from, and followed, cultivation and wind erosion of the area in the eighteenth century. 4. Vegetation on the ridges consists of trees, primarily black oak and gray birch, forming an open canopy, with a scattering undergrowth of forbs, especially Polygonella articulata, grasses, shrubs, and occasional mats of mosses and lichens. Truncated soils have an extremely open cover of Andropogon scoparius and Trichostema dichotomum. Increase in abundance and cover is brought about chiefly through un...read more

Rates of Succession and Soil Changes on Southern Lake Michigan Sand Dunes
TL;DR: Soil analyses of carbon, nitrogen, moisture equivalent, carbonates, acidity, and cation exchange relations show how most soil improvement of the original barren dune sand occurs within about a thousand years after stabilization, which fits into a mathematical framework for analyzing ecological succession and climax.

Spatial dynamics of a primary succession: nucleation
G. A. Yarranton,R. G. Morrison +1 more
TL;DR: Detailed examination of the pattern of vegetation on the ground before, during and after a stage-to-stage transition in a succession might not only clarify the sequence of spatial pattern but also help to elucidate the mechanism of succession itself.

The evolutionary ecology of nut dispersal
TL;DR: This review summarizes the widespread horticultural, botanical, and ecological literature pertaining to nut dispersal in Juglans, Carya, Quercus, Fagus, Castanae, Castanopsis, Lithocarpus, Corylus, Aesculus, andrunus to examine the evolutionary histories of these mutualistic interactions.

Population Trends in Grassland, Shrubland, and Forest Birds in Eastern North America
TL;DR: This paper examined the evidence for population declines in three important ecological groups: forest migrants, grassland species, and shrubland species and found that these three relatively specialized birds include a large proportion of the songbird species in eastern North America.

Nature and Structure of the Climax
TL;DR: In this paper, the authors discuss the nature of the climax and the role of the constituent species: dominants, influents, seral units, association, society, and community functions.
