Excerpt from On the Geographic Distribution and Ecological Relations of the Bog Plant Societies of North America
The preservation of the bog societies in poorly drained situa tions down to the present time seems to be due (1) to the lower temperatures prevailing there, (2) to the sterile nature of the sub stratum, (3) to the completeness with which the substratum is occupied by the bog plants, and (4) to the fact that most bog habitats are associated with lakes, whose basins must be entirely filled with débris, before the' drainage conditions will be naturally improved and made more favorable for the coming in of other plant societies.
To account for the xerophytic character of many of the bog plants, experiments now being carried on seem to indicate that differences of temperature between substratum and air is ade quate. But the presence in many of our bog habitats of swamp species which show no xerophytic adaptations suggests that such xerophytic structures may be unnecessary under present con ditions in this region.

Verkäuferbewertung 4 von 5 Sternen
Paperback. Zustand: New. Print on Demand. This book examines the distribution of bog plants in northern North America and their relationship to surrounding vegetation. The author argues that the distribution of bog plants is a result of past glaciations and that they are now found in areas that were once covered by glaciers. The book provides a detailed account of the different types of bog plants and their distribution, as well as a discussion of the factors that affect their growth and survival. The book also explores the relationship between bog plants and the surrounding vegetation, arguing that the two types of vegetation are often found together in a mutually beneficial relationship. The author provides examples of this relationship in different parts of North America and discusses the implications for the conservation of both bog plants and the surrounding vegetation. This book is a valuable resource for anyone interested in the ecology of bog plants and their relationship to the surrounding vegetation. It provides a comprehensive overview of the topic and is written in a clear and concise style. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
