Advances in Algal Biology: A Commemoration of the Work of Rex Lowe was written by students and colleagues of Rex Lowe to acknowledge his esteemed career that included exceptional contributions to research and teaching. Papers in the book cover a variety of topics in algal ecology, focusing on benthic algal ecology in freshwater ecosystems. The studies provide an unusual combination of small-scale experiments and large-scale regional surveys that bridge both basic and applied ecology. Ecologists, limnologists, phycologists, and environmental scientists will find valuable contributions to the development and application of algal research.

Increasing awareness of the deleterious effects of toxic components in antifouling coatings has raised interest in the potential for nontoxic alternatives. This book examines how marine organisms from bacteria to invertebrates and plants use chemicals to communicate and defend themselves. Chemicals that prevent colonisation of living surfaces are particularly pertinent to antifouling technology and may inspire new solutions. The challenge is to identify such compounds, identify the means for sustainable production and incorporate them into coatings to give long-term antifouling efficacy.

This volume presents new and additional information about the physiology and ecology of halophytic plant species and saline ecosystems. The halophytes are highly specialized plants, which have greater tolerance to salt. They can germinate, grow and reproduce successfully in saline areas which would cause the death of regular plants. Most halophytic species are found in salt marsh systems along seashores or around landlocked inland lakes and flat plains with high evaporation. The halophytes play very significant role in the saline areas specially in the coast by overcoming the salinity in different ways, viz. with regulating mechanisms in which excess salts are excreted and with out regulating mechanism, which may include succulents or cumulative types. Besides that they protect coast from erosion and cyclones, provide feeding ground and nursery for fish, shrimps and birds. Halophytes get increasing attention today because of the steady increase of the salinity in irrigation systems in the arid and semi-arid regions where the increasing population reaches the limits of freshwater availability. In many countries, halophytes have been successfully grown on saline wasteland to provide animal fodder and have the potential for rehabilitation and even reclamation of these sites. The value of certain salt-tolerant grass species has been recognized by their incorporation in pasture improvement programs in many salt affected regions throughout the world. There have been recent advances in selecting species with high biomass and protein levels in combination with their ability to survive a wide range of environmental conditions, including salinity. Our limited understanding of how halophytes work, as this may well be our future as our limit of fresh water is reached. It is important that we preserve these unusual plants and their habitats, not just for their aesthetic beauty, but also as a resource for the development of new salt tolerant and halophyte crop of economic importance. Over the last ten years much new information has become available, which is important for agriculture, forestry and floriculture.

Anisoptera is the first of two volumes on the Odonata in the series Encyclopedia of South American Aquatic Insects. The second will treat the Zygoptera. The Anisoptera volume encompasses the large dragonfly species. A brief review of the biology of the group includes illustrations of the main morphological features as well as explanations of alternative systems for naming the wing veins and other structures.  This will prepare the user of the volume to understand the different names for the same structures that he will encounter in the literature.    The review is then followed by keys to facilitate identification of the adult dragonflies and the known larvae, allowing the user a high probability of identifying his specimens correctly.  In addition to anatomical features, the keys include the known ranges of the species, synonyms, and citations of literature in which more information about each individual species can be obtained.  These citations are compiled in an extensive bibliography, including titles of the original publications in which descriptions of almost all South American species appeared.  Although taxonomic revisions are deliberately avoided, suggestions for additional research are provided where the validity of taxa seems doubtful.  To provide the user with the best possible opportunity to distinguish the species, the keys are richly illustrated with pen and ink drawings of thousands of individual morphological structures arranged in 797 figures.  It is certain that significant changes will occur in the systematics of South American dragonflies in the future, and this book should provide the impetus needed to accelerate the revisional work.  Meanwhile, it will provide a comprehensive overview of the Anisoptera in South America that is otherwise unavailable to most South American scientists because of the great difficulties in obtaining the hundreds of publications from numerous countries in which the descriptions and revisions of the species appeared.  It also provides young entomologists with a basic text for learning what they need to know to work effectively with the Anisoptera of South America and adjacent regions.  Already published within this encyclopedia: -Encyclopedia of South American Aquatic Insects: Collembola ISBN: 0-7923-6704-9 -Encyclopedia of South American Aquatic Insects: Ephemeroptera ISBN: 1-4020-0775-2 -Encyclopedia of South American Aquatic Insects: Plecoptera ISBN: 1-4020-1520-8 Forthcoming book titles: Forthcoming book titles: -Encyclopedia of South American Aquatic Insects: Odonata - Zygoptera -Encyclopedia of South American Aquatic Insects: Orthoptera -Encyclopedia of South American Aquatic Insects: Heteroptera; -Encyclopedia of South American Aquatic Insects: Neuroptera, including Megaloptera -Encyclopedia of South American Aquatic Insects: Trichoptera -Encyclopedia of South American Aquatic Insects: Lepidoptera -Encyclopedia of South American Aquatic Insects: Coleoptera -Encyclopedia of South American Aquatic Insects: Diptera -Encyclopedia of South American Aquatic Insects: Hymenoptera.

This volume presents selected contributions given to the 38th European Marine Biology Symposium, held in Aveiro, Portugal, in September 2003. Understanding the functioning of Marine Ecosystems is the first step to measure and predict the influence of Man, and to find solutions for the enormous array of problems we face today. This volume is organised according to the four subthemes of the symposium and to issues commonly perceived as relevant by scientists concerned with the study, protection and management of Marine Biodiversity: patterns and processes, assessment, threats and management and conservation. The 32 papers that make up this book represent the current research and concerns about Marine Biodiversity in Europe, and will have wide appeal to all those interested in understanding and preserving the marine ecosystems of the world's oceans. Reprinted from HYDROBIOLOGIA volume 555(2006).
