Peatlands form important landscape elements in many parts of the
world and play significant roles for biodiversity and global carbon
balance. This new edition has been fully revised and updated,
documenting the latest advances in areas such as microbial
processes and relations between biological processes and hydrology.
As well as thoroughly referencing the latest research, the authors
expose a rich older literature where an immense repository of
natural history has accumulated. The Biology of Peatlands starts
with an overview of the main peatland types (marsh, swamp, fen, and
bog), before examining the entire range of biota present (microbes,
invertebrates, plants, and vertebrates), together with their
specific adaptations to peatland habitats. Detailed coverage is
devoted to the genus Sphagnum, the most important functional plant
group in northern peatlands, although tropical and southern
hemisphere peatlands are also covered. Throughout the book the
interactions between organisms and environmental conditions
(especially wetness, availability of oxygen, and pH) are
emphasized, with chapters on the physical and chemical
characteristics of peat, the role of peat as an archive of past
vegetation and climate, and peatland succession and development.
Several other key factors and processes are then examined,
including hydrology and nutrient cycling. The fascinating peatland
landforms in different parts of the world are described, together
with theories on how they have developed. Human interactions with
peatlands are considered in terms of management, conservation, and
restoration. A final chapter, new to this edition, focuses on the
role of peatlands as sources or sinks for the greenhouse gases
carbon dioxide and methane, and the influences of climate change on
peatlands. This timely and accessible text is suitable for students
and researchers of peatland ecology, as well as providing an
authoritative overview for professional ecologists and conservation
biologists.
This title is part of UC Press's Voices Revived program, which
commemorates University of California Press's mission to seek out
and cultivate the brightest minds and give them voice, reach, and
impact. Drawing on a backlist dating to 1893, Voices Revived makes
high-quality, peer-reviewed scholarship accessible once again using
print-on-demand technology. This title was originally published in
1979.
Coastal Management: Global Challenges and Innovations focuses on
the resulting problems faced by coastal areas in developing
countries with a goal of helping create updated management and
tactical approaches for researchers, field practitioners, planners
and policymakers. This book gathers, compiles and interprets recent
developments, starting from paleo-coastal climatic conditions, to
current climatic conditions that influence coastal resources.
Chapters included cover almost all aspects of coastal area
management, including sustainability, coastal communities, hazards,
ocean currents and environmental monitoring.

Special Volume on Kogia biology presents in-depth and up-to-date
reviews on all aspects of marine biology. Published since 1963,
this serial updates on a variety of topics that will appeal to
postgraduates and researchers in marine biology, fisheries science,
ecology, zoology and biological oceanography.
This book comprises 41 s dealing various issues, prospects and
importance of conservation agriculture practices followed across
different regions with special emphasis on rainfed regions. We hope
this book on conservation agriculture will be highly useful to
researchers, scientists, students, farmers and land managers for
efficient and sustainable management of natural resources.
Soil Science is an important and basic science in agriculture which
deals with different domains of soil research namely, soil
formation, genesis and classification, soil physics, soil
chemistry, soil fertility and plant nutrition, soil biology, etc.
Characterization as well as our understanding of soils requires
that they are precisely analysed and described. While the physical
properties of soils determine their adaptability to cultivation,
chemical properties tells about their chemical environment and
nutrient status to the crop production - the most important use of
soils on this densely populated planet. Determination of different
soil physical and chemical properties in the field or in the
laboratory following suitable analytical methods is first step
towards appropriate soil managements and scientific recommendations
for increasing crop production.
Most livestock in the United States currently live in cramped and
unhealthy confinement, have few stable social relationships with
humans or others of their species, and finish their lives by being
transported and killed under stressful conditions. In Livestock,
Erin McKenna allows us to see this situation and presents
alternatives. She interweaves stories from visits to farms,
interviews with producers and activists, and other rich material
about the current condition of livestock. In addition, she mixes
her account with pragmatist and ecofeminist theorizing about
animals, drawing in particular on John Dewey's account of
evolutionary history, and provides substantial historical
background about individual species and about human-animal
relations. This deeply informative text reveals that the animals we
commonly see as livestock have rich evolutionary histories,
species-specific behaviors, breed tendencies, and individual
variation, just as those we respect in companion animals such as
dogs, cats, and horses. To restore a similar level of respect for
livestock, McKenna examines ways we can balance the needs of our
livestock animals with the environmental and social impacts of
raising them, and she investigates new possibilities for humans to
be in relationships with other animals. This book thus offers us a
picture of healthier, more respectful relationships with livestock.
Over the last five centuries, North-East England's River Tyne went
largely with the flow as it rode with us on a rollercoaster from
technologically limited early modern oligarchy, to large-scale
Victorian 'improvement', to twentieth-century deoxygenation and to
twenty-first-century efforts to expand the river's biodiversity. By
studying five centuries of Tyne conservatorship, we can see that
1855 to 1972 was a blip on the graph of environmental concern,
preceded and followed by more sustainable engagement and a fairer
negotiation with the river's forces and expressions as a whole and
natural system, albeit driven by different motivations. Even during
this blip, however, many people expressed environmental concern.
Several organisations, including the Tyne Salmon Conservancy
(1866-1950), local governors, the Tyne's anglers and the Standing
Committee on River Pollution's Tyne Sub-Committee (1921-1939),
tried to protect the river's environmental health from harm, as
they perceived it. This Tyne study offers a template for a future
body of work on British rivers that shakes off the straitjacket of
the Thames as the river of choice in British environmental history.
And it undermines traditional socio-cultural approaches which
reduce rivers to passive backdrops of human activities. Departing
from progressive narratives that equated change with improvement,
and declensionist narratives that equated change with loss and
destruction, it moves away from morally loaded notions of better or
worse, and even dead, rivers. This book refocuses on the production
of new and different rivers and fully situates the Tyne's fluvial
transformations within their political, economic, cultural, social
and intellectual contexts. Let us sit with the Tyne itself, some of
its salmon, a seventeenth-century Tyne River Court Juror, some
nineteenth-century Tyne Improvement Commissioners, a 1920s
biologist, a twentieth-century Tyne angler, shipbuilder and council
planner and some twenty-first-century Tyne Rivers Trust volunteers.
What would they disagree about? Would they agree on anything? How
would they explain their conceptualisation of what the river is for
and how it should be used and regulated? This book takes you to the
heart of such virtual debates to revive, reconnect and reinvigorate
the severed bonds and flows linking riparian places, issues and
people across five centuries. By analysing the Tyne's past
conservatorships, we can objectify ourselves through our
descendants' eyes, reconnecting us not only to our past, but also
to our future.
