The BIOGEOMON conference, held in Prague, September 1993, was
dedicated to the use of geochemistry and biology in the elucidation
of biogeochemical processes in the context of research on small
catchments, which are natural systems that lend themselves to the
study of environmental problems at the ecosystem level.
Biogeochemical Monitoring in Small Catchments, which contains
reviewed papers from the conference, includes long-term studies of
nutrient cycling in forested catchments, effects of anthropogenic
action on streamwater chemistry, stable isotope studies for tracing
biogeochemical processes, determination of the process rates, and
mathematical modelling of ecosystem behaviour and mass fluxes. For
research scientists and students of ecology, biology, hydrology and
geochemistry as well as professionals in natural resources
management.
This atlas gives a comprehensive account on the benthic
foraminiferal fauna in the China Seas, especially on the Bohai and
the Yellow Seas. Details of about 183 species, subjected to 5
orders, 52 families and 92 genera are included. For each species
there is a brief description of the morphological characteristics,
synonymised names, measurements and geographical distribution
worldwide, as well as a top-level elegant plate illustrated the
fossil and live specimens. It could be used as a reference book for
researchers working at marine biology, marine geology,
micropaleontology, paleoceanography, paleobiology and related
fields.
This book is open access under a CC BY-NC 4.0 license. It explores
the diverse phenomena which are challenging the international law
of the sea today, using the unique perspective of a simultaneous
analysis of the national, individual and common interests at stake.
This perspective, which all the contributors bear in mind when
treating their own topic, also constitutes a useful element in the
effort to bring today's legal complexity and fragmentation to a
homogenous vision of the sustainable use of the marine environment
and of its resources, and also of the international and national
response to maritime crimes.The volume analyzes the relevant legal
frameworks and recent developments, focusing on the competing
interests which have influenced State jurisdiction and other
regulatory processes. An analysis of the competing interests and
their developments allows us to identify actors and relevant legal
and institutional contexts, retracing how and when these elements
have changed over time.

Historically, it is the land of the bison. But the land across
which these powerful herds once thundered has been transformed. We
know it today by such names as Montana, Wyoming, Dakota, western
Iowa, and Nebraska--but it is really buffalo country, the land of
the big sky rivers. This book is a tale of two rivers, a history of
the majestic Missouri and how it was once wedded to the
Yellowstone. Though quite different today--one dammed into
reservoirs, the other unregulated with a semblance of
wildness--they were once linked ecologically, geographically, and
historically. Then in the twentieth century, Euro-Americans
dismantled many of these connections and attempted to uncouple the
streams. Viewing the rivers and their surrounding lands as a living
system, Robert Kelley Schneiders focuses on four components within
the Upper Missouri bioregion--the Missouri River valley, the
Yellowstone River valley, Homo sapiens, and bison--to show the
significance of their interaction over the past two hundred years.
To frame his story, Schneiders goes back to the nineteenth-century
journals of fur traders and settlers, and in the record of flora,
fauna, floods, and human activity he finds evidence of rapid and
disruptive change. Bison once had the greatest influence on the
land, and Schneiders depicts an original bison and Indian trail
network on which were overlaid the first forts and towns and then
the railroads, highways, and reservoirs that reconfigured the
region forever. Schneiders explains how these geographical
constructs interacted with larger demographic and economic trends
in the twentiety-century West, as dams and their resultant
reservoirs enhanced the federal presence in the Dakotas andeastern
Montana. He describes human encroachment on the rivers and tells
why the Corps of Engineers dammed the Missouri but spared the
Yellowstone. The engineers and their backers have so completely
engineered the Missouri that few people today think of it as
anything other than water. But we can reestablish our bonds to the
river if we decide to let it flow once again, argues Schneiders.
Removing the dams on the Missouri is the first step toward
reasserting localism and grassroots democracy. In what was once
buffalo country, a dormant ecology awaits rebirth. A major work of
environmental history, "Big Sky Rivers offers a challenging vision
for the future of the Upper Missouri bioregion.
This book offers a comprehensive review of the landscapes and
ecosystems of the Upper Yellow River. It focuses on landscapes as a
platform for considering environmental values and issues across the
region. The book is based on extensive field-based analyses,
applications, and photographs.
This volume offers an overview of the occurrence of emerging
organic contaminants in Mediterranean rivers and their relevance to
their chemical and ecological quality under water scarcity. With
chapters covering the effects under multiple stress conditions of
pharmaceuticals, polar pesticides, personal care products, and
industrial chemicals, the observations presented can be applicable
to other parts of the world where water scarcity is an issue . It
is of interest to environmental chemists, ecologists, environmental
engineers, and ecotoxicologists, as well as water managers and
decision-makers.
Integrating information from several areas of engineering geology,
hydrogeology, geotechnical engineering, this book addresses the
general field of groundwater from an engineering perspective. It
covers geological engineering as well as hydrogeological and
environmental geological problems caused by groundwater
engineering. It includes 10 chapters, i.e., basic groundwater
theory, parameter calculation in hydrogeology, prevention of
geological problem caused by groundwater, construction dewatering,
wellpoint dewatering methods, dewatering wells and drilling,
groundwater dewatering in foundation-pit engineering, groundwater
engineering in bedrock areas, numerical simulation in groundwater
engineering, groundwater corrosion on concrete and steel. Based on
up-to-date literature, it describes recent developments and
presents several case studies with examples and problems. It is an
essential reference source for industrial and academic researchers
working in the groundwater field and can also serve as
lecture-based course material providing fundamental information and
practical tools for both senior undergraduate and postgraduate
students in fields of geology engineering, hydrogeology,
geotechnical engineering or to conduct related research.
Papers presented at the 10th in a series of conferences on River
Basin Management are contained in this book. The included works
mark a growing global interest in the planning, design and
management of river basin systems and take in to account all
aspects of Hydrology, Ecology, Environmental Management, Flood
Plains and Wetlands. Catastrophic events such as floods and
associated landslides, erosion and sedimentation can have serious
effects not only on life and property but also on the basin
ecology. Frequently these problems are aggravated by the unforeseen
consequences of man made changes in the river basin. This has led
in recent years to work on river restoration and rehabilitation
with various degrees of success. Changes in the landscape, use of
the land and climate conditions leads to a continuous revaluation
of river basin management objectives requiring the development of
better measuring tools in conjunction with accurate computer
technology. Specific themes covered in this volume include: Water
resources management; Flood risk management; Ecological and
environmental impact; Erosion and sediment transport; Hydrological
modelling; River restoration and rehabilitation; Hydropower issues
and development; River and watershed management; Water quality
issues; Organic contamination management; Agricultural pollution;
Transboundary water issues; Estuaries and deltas; Climate change;
Remote sensing; Hydraulic structures; Rain water management; Water
energy nexus; Drought assessment and management; Ecosystem
services.
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.
The coastal and ocean ecosystem is a significant feature of our
planet and provides a source of food for much of life on Earth.
Millions of species have been, and are still being discovered in
the world's oceans. Among these zooplankton serve as secondary
producers and are significant as they form pelagic food links and
act as indicators of water masses. They constitute the largest and
most reliable source of protein for most of the ocean's fishes. As
such, their absence or depletion often affects fishery. In many
countries, the decline in fishery has been attributed to reduced
plankton populations. Furthermore, trillions of tiny copepods
produce countless faecal pellets contributing greatly to the marine
snow and therefore accelerating the flow of nutrients and minerals
from the surface waters to the seabed. They are phylogenetically
highly successful groups in terms of phylogenetic age, number of
living species and success of adaptive radiation. A study of the
basic and applied aspects of zooplankton would provide an index of
the fishery potential and applications, offering insights into
ocean ecology to safeguard food supplies and livelihoods of the
millions of people living in coastal areas. For this reason, we
need to understand all the facets of zooplankton as well as their
interactions with atmosphere and other life forms, including human.
In this context, this book discusses the basic and applied aspects
of zooplankton, especially taxonomy, mosquitocidal activity,
culture, analysis of nutritional, pigments and enzyme profile,
preservation of copepods eggs, bioenrichment of zooplankton and
application of zooplankton in sustainable aquaculture production,
focusing on novel biofloc-copefloc technologies, and the impact of
acidification and microplastics on zooplankton. Offering a
comprehensive overview of the current issues and developments in
the field of environmental and commercial applications, this book
is a valuable resource for researchers, aquaculturists,
environmental mangers wanting to understand the importance of
zooplankton and develop technologies for the sustainable production
of fish and other commodities to provide food and livelihoods for
mankind.

This book offers a comprehensive review of current systems for fish
protection and downstream migration. It offers the first systematic
description of the currently available technologies for fish
protection at hydropower intakes, including accurate and timely
data collected by the authors and other researchers. It describes
how to design and test them in agreement with the guidelines
established from the EU Water Framework Directive. The book
includes important information about fish biology, with a special
focus on swimming and migration mechanisms. It offers a robust
bridge between concepts in applied ecology and civil hydraulic
engineering, thus providing biologists and hydraulic engineers with
an authoritative reference guide to both the theory and practice of
fish protection. It is also of interest for planners, public
authorities as well as environmental consultants
This comprehensive book contains contributions from specialists who
provide a complete status update along with outstanding issues
encompassing different topics related to deep-sea mining. Interest
in exploration and exploitation of deep-sea minerals is seeing a
revival due to diminishing grades and increasing costs of
processing of terrestrial minerals as well as availability of
several strategic metals in seabed mineral resources; it therefore
becomes imperative to take stock of various issues related to
deep-sea mining. The authors are experienced scientists and
engineers from around the globe developing advanced technologies
for mining and metallurgical extraction as well as performing deep
sea exploration for several decades. They invite readers to learn
about the resource potential of different deep-sea minerals, design
considerations and development of mining systems, and the potential
environmental impacts of mining in international waters.

Lakes across the globe require help. The Lake Restoration Handbook:
A New Zealand Perspective addresses this need through a series of
chapters that draw on recent advances in modelling and monitoring
tools, citizen science and First Peoples' roles, catchment and
lake-focused restoration techniques, and policy implementation. New
Zealand lakes, like lakes across the globe, are subject to multiple
pressures that have increased in severity and scale as land use has
intensified, invasive species have spread and global climate change
becomes manifest. This books builds on the popular Lake Managers
Handbook (1987), which provided guidance on undertaking
investigations into, and understanding lake ecosystems in New
Zealand. The Lake Restoration Handbook: A New Zealand Perspective
synthesises contemporary issues related to lake restoration and
rehabilitation, integrated with social science and cultural
viewpoints, and complemented by authoritative topic-area summaries
by renowned scientists and practitioners from across the globe. The
book examines the progress of lake restoration and the new and
emerging tools available to managers for predicting and effecting
change. The book will be a valuable resource for natural and social
scientists, policy writers, lake managers, and anyone interested in
the health of lake ecosystems.
This original analysis of the Middle East water problems highlights
questions and issues which have so far only received minimal
attention. The author develops a multi-layered account of the
nature and causes of the conflict and the Pealestinian water
crisis. Each chapter addresses a particular aspect of the
Israeli-Palestine water conflict and the author uses these to
illustrate both the broader nature of Israeli-Palestinian relations
and factors that the existing water literature underplays or simply
gets wrong. The book should interest students, scholars and
practitioners in a wide range of disciplines including Middle East
studies, politics and international relations, water policy,
geography, environmental studies and environmental management.
This book highlights perspectives, insights, and data in the
coupled fields of aquatic microbial ecology and biogeochemistry
when viewed through the lens of collaborative duos - dual career
couples. Their synergy and collaborative interactions have
contributed substantially to our contemporary understanding of
pattern, process and dynamics. This is thus a book by dual career
couples about dual scientific processes. The papers herein
represent wide-ranging topics, from the processes that structure
microbial diversity to nitrogen and photosynthesis metabolism, to
dynamics of changing ecosystems and processes and dynamics in
individual ecosystems. In all, these papers take us from the Arctic
to Africa, from the Arabian Sea to Australia, from small lakes in
Maine and Yellowstone hot vents to the Sargasso Sea, and in the
process provide analyses that make us think about the structure and
function of all of these systems in the aquatic realm. This book is
useful not only for the depth and breadth of knowledge conveyed in
its chapters, but serves to guide dual career couples faced with
the great challenges only they face. Great teams do make great
science.
Do you know silica, the tetrahedra of silicon and oxygen
constituting the crystals of New Agers and the desiccant in a box
of new shoes? It's no mere mundane mineral. As chemically reacting
silicate rocks, silica set off the chain of events known as the
origin of life. As biomineralized opal, it is the cell wall,
skeleton, spicules, and scales of organisms ornamenting numerous
lobes of the tree of life. Cryptocrystalline silica made into stone
tools helped drive the evolution of our hands and our capability
for complex grammar, music, and mathematics. As quartz crystals,
silica is impressively electric and ubiquitous in modern technology
(think sonar, radios, telephones, ultrasound, and cheap but precise
watches). Silica is inescapable when we take a drink or mow the
lawn and it has already started to save the Earth from the carbon
dioxide we're spewing into the atmosphere. This book tells these
scientific tales and more, to give dear, modest silica its due.
This text, written by a leading researcher in the field, describes the origin and formation of lakes in order to give context to the question of how lacustrine deposits form. It explains the process of sedimentation in lakes and the chemistry of those deposits and describes how the age of lake deposits is determined. Additionally, this book shows how different groups of fossils are used in interpreting the paleontological record of lakes. In order to illustrate the more synthetic approaches to interpreting the history of lakes, the author also discusses such special topics as lake-level history, lake evolution, and the impact of environmental change on lakes.
Fisheries resources are an important component of natural
resources. It is an important source of high-quality animal protein
and food for humans, which provides employment, economic benefits
and social welfare for people engaged in fishing activities. It
also has played an important role in food safety, economic
development, and foreign trade. Fisheries resources economics is an
important branch of both applied economics and resource economics.
Its research object is fishery resources and its economic problems.
The economics of fishery resources is to focus on the relationship
between the demand for human economic activities and the supply of
fishery resources, as well as between fishery resources and its
development. This book expounds the reasons for the economic
problems of fishery resources and the theoretical principles for
solving them, so as to reveal the objective rules of the allocation
of fishery resources in different regions and at different times,
to coordinate the relationship between the utilization of fishery
resources and economic development, and to realize the sustainable
development of fishery economy. This book will also provide
learning materials for undergraduates, graduate students and
practitioners engaged in fishery resources development and
scientific management.
This book focuses on how marine systems respond to natural and
anthropogenic perturbations (ENSO, overfishing, pollution, tourism,
invasive species, climate-change). Authors explain in their
chapters how this information can guide management and conservation
actions to help orient and better manage, restore and sustain the
ecosystems services and goods that are derived from the ocean,
while considering the complex issues that affect the delicate
nature of the Islands. This book will contribute to a new
understanding of the Galapagos Islands and marine ecosystems. "
Reef fish spawning aggregations, ranging from small groups to many
tens of thousands of individuals, are spectacular but poorly known
natural phenomena whereby fish assemble at specific times and
locations to spawn. For some species these large groups may be the
only form of reproduction, the high fish numbers briefly giving a
false impression of stability and abundance-an 'illusion of
plenty'. They are often a focus for intensive seasonal fishing
because of their predictability and because many important
commercial fishes form them. Highly vulnerable to overexploitation,
many aggregations and their associated fisheries, have disappeared
or are in decline. Few are effectively managed or incorporated into
protected areas. Aggregations are not well understood by fishery
scientists, managers and conservationists and their significance
little appreciated by fishers or the wider public. To ensure their
persistence to replenish important fisheries in coral ecosystems,
maintain their ecosystem function and continue to delight divers, a
significant change in perspective is needed to foster protection
and management. This book provides comprehensive and practical
coverage of the biology, study and management of reef fish
aggregations, exploring their how, when, where, and why. It
explores ways to better protect, study, manage and conserve them,
while identifying key data gaps and questions. The text is
extensively illustrated with many unique, never before published,
photographs and graphics. Case studies on over 20 interesting and
important fishes are included, outlining their biology and
fisheries and highlighting major concerns and challenges.
This book reviews the latest research and developments concerning
the biodiversity and biocontamination assessment of aquatic
ecosystems in Poland. The authors present expert analyses of the
current biological status of Polish surface waters, and examine a
broad range of elements related to aquatic ecosystems, including
macrophytes, phytoplankton, zooplankton and macroinvertebrates,
microorganisms, fish, and selected invasive aquatic species. A set
of conservation and restoration practices, and a review of
protected sites within the Polish basins and catchment areas, are
also provided. This book and the companion volume Polish River
Basins and Lakes - Part I: Hydrology and Hydrochemistry offer
valuable resources for students, environmental chemists,
biologists, geologists, hydrologists and surface waters managers
interested in the environmental conditions of Poland's surface
waters.
