Rotifera IX


Book Description

This volume is a record of the proceedings of the IXth International Rotifer Symposium, which was held in Khon Kaen, Thailand, on January 16-23, 2000. The symposium was the first meeting of the international group of rotifer researchers held in Asia. The volume contains reviews and research papers dealing with diverse aspects of scientific research related to Rotifera and their ecology. Some of the topics addressed are: taxonomy and zoogeography, ecology, phylogeny and evolution, physiology, biochemistry and population genetics, aquaculture, and ecotoxicology. This book is special because it contains a unique compilation of contemporary rotifer-related research, and is the eighth of a series of rotifer symposium proceedings published in Developments of Hydrobiology. This update of Rotifera studies will be of great interest to invertebrate zoologists, hydrobiologists, ecologists, and aquaculturists, particularly those interested in freshwater habitats.




Aquatic Birds in the Trophic Web of Lakes


Book Description

Birds are an integral part of most freshwater ecosystems (lakes, rivers, wetlands) but their role in the trophic dynamics of these water bodies has often been overlooked. As a conspicuous part of the biota of water bodies, aquatic birds are indicators of their trophic state both in terms of species composition (quality) as well as occupancy and breeding (quantity). Birds may also influence the trophic state of a water body by importing nutrients (.e.g. resident or migrating birds feeding on adjacent watersheds or the sea). Because of anthropogenic activities, predation or their mobility, birds may not utilize otherwise suitable aquatic habitat. These factors complicate the relationship between aquatic bird production and the trophic status of habitats. As a consequence, the role of aquatic birds in freshwater ecosystems has usually been ignored. This volume contains a wide range of papers selected from those presented at the symposium and reviewed.

Motu River


Book Description

"This report documents information collected during hydro-electric power development investigations and during investigtions leading up to the Motu River water conservation order hearings. The report describes water, soil and sediment characteristics of the river and its catchment and some of the recreational and scenic qualities of the river. The granting of a national water conservation order has for the time being removed the possibility of any development of the water resource of the Motu River. However the order does not permanently foreclose the development option. The possible effects on the river and the coastline of previous development proposals are examined in this report."--Foreword.
