Honey bees (Apis mellifera L.) are the main pollinating agents for numerous
plants and fruit trees and, hence, play a key role in agriculture and
more generally in the maintenance of ecological biodiversity. Although
these social insects are not the targets of all the different agrochemical
treatments used in crop protection, they are widely affected by pesticides.
The long-term approach to achieving protection is “ecological separation.” A true ecological
separation is defined as no inter-basin transfer of aquatic organisms via the Chicago Waterway
System at any time – 100% effectiveness. Ecological separation prohibits the movement or interbasin
transfer of aquatic organisms between the Mississippi and Great Lakes basins via the CWS.
Once established, the impacts of invasive species on ecosystem health are permanent and
The epidemiology of infectious diseases is one of the great triumphs of applied
ecology. In particular, the public health importance of parasites has
lead to a large literature, exploring their impact on the population dynamics,
population genetics and evolutionary biology of human populations. An
important milestone was the Dahlem Conference on population biology of infectious
diseases, held in 1981. The resulting book (Anderson and May 1982)
lucidly summarised the contemporary state of parasite ecology and epidemiology.
These related changes have locked the global economy and global ecology together in new
ways. We have in the past been concerned about the impacts of economic growth upon the
environment. We are now forced to concern ourselves with the impacts of ecological stress -
degradation of soils, water regimes, atmosphere, and forests upon our economic prospects.
We have in the more recent past been forced to face up to a sharp increase in economic
interdependence among nations. We are now forced to accustom ourselves to an accelerating
ecological interdependence among nations.
Because of its accessibility, the intertidal zone has offered
excellent opportunities to study the adaptations of individual
organisms and populations to their environment,
and the factors controlling community composition. Early
work on seashores concentrated on the problems of life
in an environment characterized by steep gradients in
physical conditions, but in more recent years, the focus
of research on the fascinating shore ecosystems has been
on understanding the processes controlling their productivity
and dynamic functioning.
The world’s climate is changing, and it will continue to change throughout the 21st century and beyond. Rising temperatures, new precipitation patterns, and other changes are already affecting many aspects of human society and the natural world. Climate change is transforming ecosystems at extraordinary rates and scales.
robably the best introduction to our book is the conclusion of another
book. The other book is Something New Under the Sunby historian J. R.
McNeill argues that the Preacher in Ecclesiastes remains mostly
but not completely right—there is indeed “nothing new under the sun” in
the realm of vanity and wickedness. But the place of humankind within the
natural world is not what it was. The enormity and devastating impact of the
human scale on the rest of creation really is a new thing under the sun. And
it greatly amplifies the consequences of vanity and wickedness.
The 8th International Congress of Ecology was held in Seoul, South Korea in
August 2002, and was hosted by the Ecological Society of Korea. The Congress
theme was 'Ecological Issues in a Changing World', and this volume includes
selected contributions to illustrate some of the important topics which were
discussed during the Congress.
Problems of scale have exercised the minds of ecologists for many years, and
will continue to do so into the future. This volume deals with this subject and with
mathematical approaches to improve our understanding of complex ecological
THOUGHTFUL OBSERVERS of global ecosystems cannot fail
to see that we live in a world dominated by humans.We
cannot stand apart from nature, and now nature as we
know it cannot stand apart from us. Faced with dawning clarity
about this new relationship, we are uncertain of what to do.
There are 4 million miles of roads in the United States. One hundred
years ago, roads were primarily unpaved and had half the number of
miles of the present U.S. road system. As the system grew, roads became
wider and more complex structurally to provide for more and heavier
traffic. New construction technology and greater structural stability
were needed to improve the road system.
All phases of road development—from construction and use by vehicles
to maintenance—affect physical and chemical soil conditions, water
flow, and air and water quality.
In 2005, the Royal College of Physicians (RCP), UK, defined well-being as ‘a holistic notion of
achieving a state of health, comfort and happiness’ (RCP, 2005). Other societies have however for
a very long time throughout the history of Western society addressed the holistic aspects of
health and the concept of ‘feeling’ or of ‘being well’.
This book is based on material from the first 12 issues of the Green Building Digest. We began to publish the digest in 1995 in an attempt to distribute information abuot the enviromental impact of building material and techniques to a wide range of people conectned with the built environment in England...
The primary purpose of preparing this edition is to provide an update. In the 14 years since
the first edition was published, ecological risk assessment has gone from being a marginal
activity to being a relatively mature practice. There are now standard frameworks and
guidance documents in the United States and several other countries. Ecological risk assessment
is applied to the regulation of chemicals, the remediation of contaminated sites, the
importation of exotic organisms, the management of watersheds, and other environmental
Human activities may seriously affect the quality of aquatic ecosystems. Pathogen
organisms, nutrients, heavy metals, toxic elements, pesticides, pharmaceuticals and
various other organic micropollutants enter to aquatic environment through a range of
point and diffuse sources. The presence of these compounds has adverse impacts on
aquatic biota. It is well recognised that the distribution and the abundance of various
species in aquatic systems are directly related to the water quality and hydrological
First and foremost, it is a book geared towards fish aquarists. And it is a heavy read with alot of chemistry and biology. To sum up the book: the author wrote the book to bring it to the reader's attention that an aquarium is a sort of (semi)closed ecosystem, and it needs to be thought of as this in order to be successful in raising the plants and animals inside the aquarium. she then describes the biological principles behind her methods of setting up and maintaining "low-tech" planted aquariums (as opposed to hi-tech, like those of takashi amano). She uses...
Environmental toxicology is the study of the impacts of pollutants upon the
structure and function of ecological systems. For the purposes of this text, the
emphasis will be upon ecological structures, from the molecular to the individual
organism to the community and the ecosystem. The broad scope of environmental
toxicology requires a multidisciplinary approach of a variety of specialists.
In response to increasing concerns about degradation of natural resources and
the sustainability of agricultural production potentials in many poor regions
of the world, many national and international organisations have initiated
research and development programmes for natural resource management
Restoration ecology is a subdiscipline of ecological engineering that has been growing out of the need and desire to add ecological value to ecosystems that have been degraded by human impacts.
Sewage sludge as an uncalled for product of wastewater treatment poses the challenge to
society of disposing of it, but at the same time gives us the opportunity of beneficial use by
closing the cycle of nutrients: sludge derived from agricultural activity must return to soil if
a sustainable and ecologically sound management of these materials is desirable (SEQUI et
al. 2000). At present the major ways of disposing of sewage sludges are deposition, landfill
and incineration, only part of the sludges are used in agriculture. ...
Operating eco-industrial park (EIP) based on industrial ecology theory has emerged since 1970s to reduce the impact of waste and save natural resources. It is especially meaningful for developing countries like Vietnam to reach sustainable development goals. The study is based on the theory of industrial ecology, the previous studies of applicable capacity in Vietnam condition and the development orientations in Hai Duong province – the study area.
