The conservation and wise utilisation of the humid tropical forests, a unique biome, are matters of great concern and importance to millions living within and around these forests and, perhaps, less directly, to the totality of mankind. These forests provide many essential products and services for mankind.

Early research on ant-plant interactions in Australia was largely confined to the economically important problem of ants harvesting surface-sown pasture seed (e. The report by Berg (1975) of widespread myrmecochory in Australia, and a burst of overseas research, stimulated research on a range of ant-plant interactions in Australia.

Old and New Fields of Old-Field Ecology In ecology, succession occupies a place similar to that of evolution in general biology. it is an eclectic reflection of recent developments in ecology and in old-field ecology in particular.

The Indian subconti At some stage during evolution, some plants devel nent is a well-recognised biogeographic region with oped appropriate morphological and physiological a distinct geological history, climate, soils and adaptations and reverted back to the aquatic and/ biota.

They have compiled work on one water plant species, Potamogeton pectinatus L., and from one lake, Lake Veluwe, as a typical case, and set out to explain the fluctuations in abundance of this water plant as influenced by eutrophication.

When two of us (Jifi Kolbek, Miroslav Sriltek) were working in North Korea on the Czech Slovak field expeditions of the early 1990s, we did not think initially of comparing our results with the vegetation of surrounding areas or of writing a book.

Compares the beech forests of eastern Asia, North America and Europe. This volume examines use and management of beech forests. It analyzes historical comparison spread and speciation since the early Tertiary. It also compares the trees and forests: growth and form of trees, species composition and populations, and forest structure.

It is in fact the study of the visible life history it remain alive as part of the plant body during the of each of the vegetative and generative organs of whole lifespan of the plant or during part of it, and the plant.

But continued effort and vigilance must be expended to insure that Mongolian society will continue to be sustained by its vegetation. This book highlights work such as conserving and restoring plant diversity in various ecosystems and makes recommendations for sustaining the vegetation basis of the nomadic Mongolian society.

However, other Arabic terms which are occasionally used in English but not as widely known, such as harrah for a basaltic lava fIeld and hima for a traditional grazing reserve, are italicised throughout the text.

Plant geographical description of the area, syntaxonomy, spatial patterns, floristic richness, structure of plant communities in relation to soil properties and herbivore influence were described for a mountain region that is difficult to access.

The main subject of this book is the interaction between diggings created by porcupines when consuming geophytes, and their influences on annual and perennial vegetation in a desert biome.
