Large terrestrial mammalian herbivores play critical roles in ecosystems by acting as regulators of energy and nutrient cycles, modulators of plant community composition and grassland-woodland transitions, agents of seed dispersal, and as prey for large carnivores. Though large herbivores represent a prominent component of mammalian assemblages throughout South and Southeast Asia, little is known about their roles in ecosystems in the region. This volume presents, for the first time, a collection of studies on the ecology of the rich and diverse large herbivore assemblages of South and Southeast Asia. Prepared by experts on herbivores of the region, it covers a comprehensive range of topics, including their evolutionary history, behavioural, nutritional, and population ecology, patterns of diversity across environmental gradients, roles as seed dispersers and regulators of plant growth, community compositions, and their conservation in the face of hunting and global change.
Found in every plant species, the diversity of endophytic micro-organisms can be extremely high within different plant organs and tissue types. In trees, their ecological roles with respect to host tree can vary from latent pathogens or saprophytes to neutral commensalists and mutualists. Given their high diversity, and their bio-active nature, endophytes are currently being associated with a role in tree health against insect herbivores and fungal pathogens, as well as improving tree properties in phytoremediation. Meanwhile there is increasing interest in the potential of some tree endophytes as new sources of drug compounds. The first book on tree endophytes in several years, and containing contributions from leading authors in the field, this book provides an important reference text for professional researchers and advanced students.
This work examines the waters of marine ports as unique integrated aquatic ecosystems. It regards marine ports as entities comprising components of natural and anthropogenic origin, including pelagic, periphytal and benthal subsystems. Using selected Black and Azov Sea ports as examples, the book discusses the hydrodynamics and water exchange, which are weakened in ports compared with open coastal zones. It reflects consequences of the presence of hydrobionts and the accumulation of organic matter, which are promoted by the variety of hard substrata and the absence of fishery. The book is divided into five main chapters. The first chapter describes the general characteristics of the marine ports at the northern coast of the Black and Azov Seas and their shipping channels. Chapters 2 to 4 discuss the main abiotic and biotic peculiarities of the pelagial, periphytal and benthal subsystems of those marine ports, and chapter 5 deals with tropho-dynamic processes in their ecosystems. A concluding section reflects recommendations how the ecosystems of ports in non-tidal seas may be ameliorated.
This book brings together the latest information on the rapid advances and developments in the field of aquatic ecology. India is very rich in terms of biological diversity due to its wide range of habitats and climatic conditions. It is home to as much as 7 per cent of the world's animal species, although it only accounts for about 2 per cent of the total landmass. The present work on biodiversity, ecology and conservation of aquatic resources represents original research in the field of aquatic biodiversity, wetland ecology and its applications with reference to the country's aquatic resources. There are 19 chapters, each contributed by an expert in his/her particular field and offering novel approaches to various topics in the area of aquatic ecosystems.
This volume summarizes recent advances in environmental microbiology by providing fascinating insights into the diversity of microbial life that exists on our planet. The first two chapters present theoretical perspectives that help to consolidate our understanding of evolution as an adaptive process by which the niche and habitat of each species develop in a manner that interconnects individual components of an ecosystem. This results in communities that function by simultaneously coordinating their metabolic and physiologic actions. The third contribution addresses the fossil record of microorganisms, and the subsequent chapters then introduce the microbial life that currently exists in various terrestrial and aquatic ecosystems. Coverage of the geosphere addresses endolithic organisms, life in caves and the deep continental biosphere, including how subsurface microbial life may impact spent nuclear fuel repositories. The discussion of the hydrosphere includes hypersaline environments and arctic food chains. By better understanding examples from the micro biosphere, we can elucidate the many ways in which the niches of different species, both large and small, interconnect within the overlapping habitats of this world, which is governed by its microorganisms.
This volume focuses on those instances when benign and even beneficial relationships between microbes and their hosts opportunistically change and become detrimental toward the host. It examines the triggering events which can factor into these changes, such as reduction in the host's capacity for mounting an effective defensive response due to nutritional deprivation, coinfections and seemingly subtle environmental influences like the amounts of sunlight, temperature, and either water or air quality. The effects of environmental changes can be compounded when they necessitate a physical relocation of species, in turn changing the probability of encounter between microbe and host. The change also can result when pathogens, including virus species, either have modified the opportunist or attacked the host's protective natural microflora. The authors discuss these opportunistic interactions and assess their outcomes in both aquatic as well as terrestrial ecosystems, highlighting the impact on plant, invertebrate and vertebrate hosts.
This book is the final installation in a three-volume series synthesizing 30 years of mercury research in the Florida Everglades. The first part of this book evaluates the occurrence of trends in both biota mercury concentrations and atmospheric mercury deposition. Through both empirical and deterministic analyses, the likely drivers of biota trends are identified. These analyses help lay the predicate for devising an overall strategy to mitigate and manage the Everglades mercury problem. The book concludes with a model analysis of the likely benefits and uncertainty attendant with implementing the leading candidate strategy for best reducing the Everglades mercury problem.

Deep inside caves, at the bottoms of oceans and lakes, beneath the ground: these concealed habitats are absent of sunlight. This strange and fascinating world of complete darkness is not a solitary place-it is inhabited by millions of life forms. Yet most humans-creatures of daylight-have never seen any of them. Until now. In this fascinating-sometimes eerie-book, extreme wildlife photographer and scientist Dante Fenolio brings the denizens of these shadowy haunts into focus. Life in the Dark shows us the many ways in which life forms have adapted to lightless environments, including refinements of senses, evolution of unique body parts, and illumination using "biological flashlights." With more than 200 mesmerizing color photographs, Life in the Dark unveils bizarre creatures like the firefly squid, the giant Amazonian catfish, the Chinese cavefish, and even the human bot fly, which lives in the darkness beneath its host's skin. Fenolio's rich and vibrant images shed new light on the world's fascinating creatures of darkness.

The object of this book is to highlight how the nascent field of sustainability science is addressing a key challenges for scientists; that is, understanding the workings of complex systems especially when humans are involved. A consistent thread in the sustainability science movement is the wide acknowledgement that greater degrees of integration across what are now segmented dimensions of extant Science and Technology systems will be a key factor in matching the most appropriate science and technology solutions to specific sustainability problems in specific places.
The global nitrogen cycle is the one most impacted by mankind.
The past decade has changed our view on many aspects of the
microbial biogeochemical cycles, including the global nitrogen
cycle, which is mainly due to tremendous advances in methods,
techniques and approaches. Many novel processes and the molecular
inventory and organisms that facilitate them have been discovered
only within the last 5 to 10 years, and the process is in progress.
This volume provides state-of-the-art updates on methods and
protocols dealing with the detection, isolation and
characterization of macromolecules and their hosting organisms that
facilitate nitrification and related processes in the nitrogen
cycle as well as the challenges of doing so in very diverse
environments. Provides state-of-the-art update on methods and protocols Deals with the detection, isolation and characterization of macromolecules and their hosting organisms deals with the challenges ofvery diverse environments."
This book provides excellent techniques for detecting and evaluating biofilms: sticky films on materials that are formed by bacterial activity and produce a range of industrial and medical problems such as corrosion, sanitary problems, and infections. Accordingly, it is essential to control biofilms and to establish appropriate countermeasures, from both industrial and medical viewpoints. This book offers valuable, detailed information on these countermeasures. It also discusses the fundamentals of biofilms, relates various substrates to biofilms, and presents a variety of biofilm reactors. However, the most important feature of this book (unlike others on the market) is its clear focus on addressing the practical aspects from an engineering viewpoint. Therefore, it offers an excellent practical guide for engineers and researchers in various fields, and can also be used as a great academic textbook.
The focus of this work is the development of models to estimate evapotranspiration (ET), investigating the partitioning between soil evaporation and plant transpiration at field and regional scales, and calculating ET over heterogeneous vegetated surfaces. Different algorithms with varying complexities as well as spatial and temporal resolutions are developed to estimate evapotranspiration from different data inputs. The author proposes a novel approach to estimate ET from remote sensing by exploiting the linkage between water and carbon cycles. At the field scale, a hybrid dual source model (H-D model) is proposed. It is verified with field observations over four different ecosystems and coupled with a soil water and heat transfer model, to simulate water and heat transfer in the soil-plant-atmosphere continuum. At the regional scale, a hybrid dual source scheme and trapezoid framework based ET model (HTEM), using remote sensing images is developed. This model is verified with data from the USA and China and the impact of agricultural water-saving on ET of different land use types is analyzed, in these chapters. The author discusses the potential of using a remote sensing ET model in the real management of water resources in a large irrigation district. This work would be of particular interest to any hydrologist or micro-meteorologist who works on ET estimation and it will also appeal to the ecologist who works on the coupled water and carbon cycles. Land evapotranspiration is an important research topic in hydrology, meteorology, ecology and agricultural sciences. Dr. Yuting Yang works at the CSIRO Land and Water, Canberra, Australia.
This book provides information about microbial mats, from early fossils to modern mats located in marine and terrestrial environments. Microbial mats layered biofilms containing different types of cells are most complex systems in which representatives of various groups of organisms are found together. Among them are cyanobacteria and eukaryotic phototrophs, aerobic heterotrophic and chemoautotrophic bacteria, protozoa, anoxygenic photosynthetic bacteria, and other types of microorganisms. These mats are perfect models for biogeochemical processes, such as the cycles of chemical elements, in which a variety of microorganisms cooperate and interact in complex ways. They are often found under extreme conditions and their study contributes to our understanding of extremophilic life. Moreover, microbial mats are models for Precambrian stromatolites; the study of modern microbial mats may provide information on the processes that may have occurred on Earth when prokaryotic life began to spread."
Yeasts are a versatile group of eukaryotic microorganisms, exhibiting heterogeneous nutritional profiles and an extraordinary ability to survive in a wide range of natural and man-associated ecosystems, including cold habitats. Cold-adapted yeasts inhabit numerous low-temperature environments where they are subjected to seasonal or permanent cold conditions. Hence, they have evolved a number of adaptation strategies with regard to growth and reproduction, metabolic activities, survival and protection. Due to their distinctive ability to thrive successfully at low and even subzero temperatures, cold-adapted yeasts are increasingly attracting attention in basic science and industry for their enormous biotechnological potential. This book presents our current understanding of the diversity and ecology of cold-adapted yeasts in worldwide cold ecosystems, their adaptation strategies, and their biotechnological significance. Special emphasis is placed on the exploitation of cold-adapted yeasts as a source of cold-active enzymes and biopolymers, as well as their benefits for food microbiology, bioremediation and biocontrol. Further, aspects of food biodeterioration are considered.
New Zealand, with its long isolation from other lands and latitudes extending from subtropical to sub Antarctic, has a unique flora and highly diverse vegetation. This book is a comprehensive description of that vegetation, ranging from its origins to the major communities within which the plants exist. The text, supported by over 300 photographs, maps and diagrams, has made an outstanding contribution to the understanding of the biology of these islands. This is a reprint of the volume originally published in 1991. Chapters 1 - 4 describe the New Zealand environment, flora and fauna. They discuss the origin, relationships, life forms and reproductive aspects of the indigenous vegetation. Chapter 5 is a synopsis of vegetation types, habitat classes and environmental processes; it also serves to define the terms that are described in the book. Chapter 6 contains an outline of the geographic divisions of the country. Chapters 7 - 9 offer expanded descriptions of plant communities, preceded, where appropriate, by information on their structure and characteristic species and genera. The concluding chapters discuss ecologic functions and processes. Vegetation of New Zealand is an essential book for botanists, ecologists, conservationists and others who love New Zealand's plants, animals and landscapes. There will also be a large audience outside New Zealand. Its natural vegetation is unique; because of this and the longevity of its evolutionary history, it has always attracted considerable global interest. "The breadth of scholarship displayed by Peter Wardle is impressive. The book as a whole is remarkably readable; testimony to that comes from this reviewer who read all 672 pages in one day and was still captivated at the end " Annals of Botany "A simple title and a great achievement. This is a great book and a major achievement by the author. It will be a source book for many years to come." Vegetation "This book is a magnificent successor to Cockayne's original Vegetation in New Zealand." Biological Conservation
This book represents a rather complicated history of encounters, changes in research interest and some very interesting results. Initially it is the very fruitful interaction of Ecology and Geology. The point of view of ecologists is extremely refreshing for hard science people. Interaction and inter-relationships are the focus of Ecology whereas the traditional sciences, such as Geology, have tried to isolate the natural phenomena so that thye could be studied in a more rigorous manner. The traditional sciences were of course natural science - based since the world to be observed was at the door step of everyone, mountains, weather patterns, plants and so forth. Chemistry and Physics were de ned after Mathematics in order to establish more precise and viable principles of the behavior of the materials that formed the world around mankind. It became quite clear that the observation of the natural world was too complicated to consider all of the possible variables which could affect an observed process or situation. The systems were simpli ed and taken into the laboratory in order to better master the phenomena observed. Physics c- cerned itself with non-reacting materials, subjected to essentially mechanical forces.
Steppes form one of the largest biomes. Drastic changes in steppe ecology, land use and livelihoods came with the emergence, and again with the collapse, of communist states. Excessive ploughing and vast influx of people into the steppe zone led to a strong decline in nomadic pastoralism in the Soviet Union and China and in severely degraded steppe ecosystems. In Mongolia nomadic pastoralism persisted, but steppes degraded because of strongly increased livestock loads. After the Soviet collapse steppes regenerated on huge tracts of fallow land. Presently, new, restorative steppe land management schemes are applied. On top of all these changes come strong effects of climate change in the northern part of the steppe zone. This book gives an up-to-date overview of changes in ecology, climate and use of the entire Eurasian steppe area and their effects on livelihoods of steppe people. It integrates knowledge that so far was available only in a spectrum of locally used languages. |
