The 47 species of Parmelina are revised on the world level. Two sections are recognized: section Parmelina with 30 species widely distributed in temperate to tropical montane regions and section Myelochroa with 17 terpene-containing species concentrated in eastern and southern Asia. The genus is most closely related to Parmotrema Massalongo. Five new species, P. crassata Hale, P. degelii Hale, P. indica Hale, P. rhytidodes Hale, and P. schindleri Hale, are described, and six new combinations proposed, P. amagiensis (Asahina) Hale, P. damaziana (Zahlbruckner) Hale, P. endoleuca (Taylor) Hale, P. irrugans (Nylander) Hale, P. jamesii (Hale) Hale, and P. pastillifera (Harmand) Hale. New combinations are also made for Hypotrachyna baguioensis (Hale) Hale and Parmotrema nylanderi (Lynge) Hale.
A world-level revision is given for the 29 species of Bulbothrix, a generic segregate of Parmelia characterized by marginal bulbate cilia and production of atranorin in the upper cortex. The genus is primarily tropical in distribution and best developed in secondary forests. The main center of speciation is Brazil with 14 species, and the genus is also well represented in Africa. The New World species have a high frequency of depsides and orcinol depsidones, whereas the Old World species usually contain & beta;-orcinol depsidones. One new species, B. klementii Hale, and one new combination, B. goebelii (Zenker) Hale, are proposed.
A journal of plant systematics, phytogeography and vegetation ecology.
After publication of the first volume of the Tropical Rain Forest, the International Journal of Mycology and Lichenology commented ``This is a welcome addition to the literature on the ecology of tropical rain forests. The book provides a wealth of data and stimulating discussions and is of great interest to ecologists interested in tropical areas.'' Whereas the first volume dealt with system-ecological aspects such as community organization and processes, the present volume concentrates on biogeographical aspects such as species composition, diversity, and geographical variation.Recent ecological research in the tropical rain forest has greatly extended our understanding of biogeographical patterns of variation in the various groups of organisms, and has revealed many of the ecological and evolutionary forces that led to the present patterns of variation. Many important systems of co-evolution between the tropical rain forest ecosystems have also come to light, and the loss of species and related damage is better understood in quantitative terms.This volume presents a comprehensive review of these and other features of the rain forest ecosystem structure, and the ecological processes operating that system. General chapters on abiotic and biotic factors are followed by specific chapters on all major groups of organisms. Prospects for the future are discussed and research needs clearly stated. Also the human exploitation of the system, its effects and its limits are discussed. The book is extensively illustrated by photographs, graphs, and tables, and comprehensive bibliographies follow each chapter. Author, systematic and subject indices complete the book.It is a must for all ecologists, agriculturists, foresters, agronomists, hydrologists, soil scientists, entomologists, human ecologists, nature conservationists, and planners dealing with tropical areas. Biologists and environmentalists will also find the volume of great interest.
