Book Description
The book on sea ice ecology is the ecology of sea ice algae and other microorganism as bacteria, meiofauna, and viruses residing inside or at the bottom of the sea ice, called the sympagic biota. Organisms as seals, fish, birds, and Polar bears relies on sea ice but are not part of this biota. A distinct feature of this ecosystem, is the disappearance (melt) every summer and re-establishing in autumn and winter. The book is organized seasonally describing the physical, optical, biological, and geochemical conditions typical of the seasons: autumn, winter, and spring. These are exemplified with case studies based on author’s fieldwork in Greenland, the Arctic Ocean, and Antarctica but focused on Arctic conditions. The sea ice ecosystem is described in the context of climate change, interests, and effects of a decreasing summer ice extent in the Arctic Ocean. The book contains an up to date description of most relevant methods and techniques applied in sea ice ecology research. This book will appeal to university students at Masters or PhD levels reading biology, geosciences, and chemistry.

Book Description
Marine hard bottoms feature some of the most spectacular and diverse biological communities on this planet. These not only contain a rich treasure of genetic, taxonomic and functional information but also deliver irreplaceable ecosystem services. At the same time, they are highly vulnerable and increasingly threatened by anthropogenic pressures. This volume has collected contributions by 50 scientists from numerous biogeographic regions, dealing with characteristics of hard bottom communities. Distributional patterns in space and time are described, followed by analyses of the intrinsic and extrinsic dynamics producing these patterns. A strong emphasis is placed on the ongoing changes occurring in the structure and diversity of these communities in response to spiralling environmental impacts, and on state-of-the-art countermeasures aiming to preserve these ecological treasures. Finally, various values of diversity are assessed, hopefully as an incentive for enhanced conservation efforts.

Book Description
Zooplankton organisms comprise very important elements of the structure and function of marine and freshwater ecosystems, not only as consumers of primary production, but also as food items for juvenile stages of several fish species. Moreover, its sensitivity to both man-made and natural changes makes zooplankton quite suitable for assessing alterations in the trophic dynamics and the ecological state of aquatic ecosystems related to changes in nutrient loading and climate. Multi-scale, spatial and temporal relationships between zooplankton variability and environmental heterogeneity are still not satisfactorily understood due to the complexity of the different aquatic ecosystems (considering both biotic and abiotic elements). Thus, the ambition of the present edition is to contribute to the understanding of the role of zooplankton by investigating ecological aspects such as the species diversity, their spatial distribution and seasonal dynamics in relation to the environmental influence in various aquatic ecosystems around the world. Topics discussed in this book include the understanding of the role of zooplankton in the transfer of pollutants through trophic food webs; plankton models to explain red tides; spatial patterns of trophy and zooplankton communities in a tropical urban reservoir; the zooplankton variation in five Greek lakes; the zooplankton community in a nuclear power station cooling reservoir; the spatio-temporal dynamics of cladocera and copepoda in the Danube River; the gelatinous zooplankton in the Namibian upwelling region; and the zooplankton community in relation to the environmental factors in a solar saltern.

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.

Book Description
Microbiome Drivers of Ecosystem Function focuses on the advancements in microbial technologies towards harnessing the microbiome for improved crop productivity and health that are at the frontier of agricultural sciences. It provides insights into the diversity of endophytic microbiomes and their potential utility in agricultural production.Increased crop yield through chemical interventions have limit thresholds and alternative, natural and/or integrated approaches are increasingly needed. Microbial inoculants among the ways in which food production efficiency can be improved. Plant growth-promoting soil organisms increase net crop uptake of soil nutrients, resulting in larger crops and higher yields of harvested food. These and other symbiotic associations between plants and microbes can ultimately be exploited for the increased food production necessary to feed the world, in addition to creating safer farming techniques that minimize ecological disruption.As a volume in the Microbiome Research in Plants and Soil series, Microbiome Drivers of Ecosystem Function serves as an ideal reference for researchers and students in the fields of agricultural biotechnology, biochemistry, environmental science, plant biology, agricultural sciences, and agricultural engineering. - Provides insights on engineered microbes in sustainable agriculture, recent biotechnological developments, and future prospects - Introduces microbes as chief ecological engineers in reinstating equilibrium in degraded ecosystems - Presents the current state and development, as well as future challenges in studying plant-microbe interactions - Discusses endophytic microbiomes and other microbial consortium with multifunctional plant growth-promoting attributes
