Book Description
In The Greenland Entomofauna an international team of 64 taxonomic specialists provide for the first time a richly illustrated guide to the identification of the ≈1200 species of Hexapods/Insects, Arachnids and Myriapods so far known to occur in the country. While the composition, origin and adaptations of the Greenland fauna has always been a challenge to biogeographers and ecologists/ecophysiologists, the provision of a tool for detailed identification of its constituent species is now particularly timely, since global climate change will expectedly have a particularly noticeable impact on biota at high latitudes. This obviously renders the feasibility of monitoring distributional range shifts of the principal components of this biota a matter of some urgency.

Book Description
Chironomidae: Ecology, Systematics Cytology and Physiology contains the proceedings of the Seventh International Symposium on Chironomidae held in Dublin in August 1979. Separating 47 papers presented in the symposium as chapters, this book focuses on Chironomidae cytology and physiology; systematics and geographic distribution; and ecology, including aspects of lotic, lentic, and pollution biology. Some papers discuss in vitro translation of Balbiani ring RNA from Chironomus tentans; the hemoglobin synthesizing tissue of Chironomus; basic patterns in chromosome evolution of the genus Chironomus (Diptera); taxonomic problems in Holarctic Chironomidae; and importance of the Chironomidae (Diptera) in biological surveillance.
The Chironomidae

Book Description
The dipteran family Chironomidae is the most widely distributed and frequently the most abundant group of insects in freshwater, with rep resentatives in both terrestrial and marine environments. A very wide range of gradients of temperature, pH, oxygen concentration, salinity, current velocity, depth, productivity, altitude and latitude have been exploited, by at least some chironomid species, and in grossly polluted environments chironomids may be the only insects present. The ability to exist in such a wide range of conditions has been achieved largely by behavioural and physiological adaptations with relatively slight morphological changes. It has been estimated that the number of species world-wide may be as high as 15000. This high species diversity has been attributed to the antiquity of the family, relatively low vagility leading to isolation, and evolutionary plasticity. In many aquatic ecosystems the number of chironomid species present may account for at least 50% of the total macroinvertebrate species recorded. This species richness, wide distribution and tolerance to adverse conditions has meant that the group is frequently recorded in ecological studies but taxonomic difficulties have in the past prevented non-specialist identification beyond family or subfamily level. Recent works, including genetic studies, have meant that the family is receiving much more attention globally.
Climate Change and Coastal Ecosystems

Book Description
Produced by a Leading Aquatic Scientist A narrative account of how estuaries around the world are being altered by human forces and human-induced global climate changes, Climate Change and Coastal Ecosystems: Long-Term Effects of Climate and Nutrient Loading on Trophic Organization chronicles a more than 40-year-old research effort conducted by Dr. Robert J. Livingston and his research team at Florida State University. Designed to evaluate system-level responses to natural and anthropogenic nutrient loading and long-term climate changes, the study focused on the northeast Gulf of Mexico river–bay systems, and concentrated on phytoplankton/benthic macrophyte productivity and associated food web organization. It addressed the changes of food web structure relative to long-term trends of climatological conditions, and was carried out using a combination of field-descriptive and experimental approaches. Details Climate Change, Climate Change Effects, and Eutrophication This book includes comparative analyses of how the trophic organization of different river–bay ecosystems responded to variations of both anthropogenic impacts and natural driving factors in space and time. It incorporates a climate database and evaluates the effects of climate change in the region. It also provides insights into the effects of nutrient loading and climate on the trophic organization of coastal systems in other global regions. Presents research compiled from consistent field sampling methods and detailed taxonomic identifications over an extended period of study Includes the methods and materials that the research team used to access the health and trophic organization of Florida’s estuaries Provides an up-to-date bibliography of estuarine publications and reports Based on a longitudinal study of anthropogenic and natural driving factors on river-estuarine systems in the northeast Gulf of Mexico, Climate Change and Coastal Ecosystems: Long-Term Effects of Climate and Nutrient Loading on Trophic Organization is useful as a reference for researchers working on riverine, estuarine, and coastal marine systems.
