Field observations in the Scottish Highlands over decades -
ptarmigan, red grouse, golden plover, dotterel, bird counts.The
author documents hatch-dates of ptarmigan and red grouse in
relation to blaeberry growth and climate. He collates field
observations on golden plover, involving proportions of
dark-plumaged summering birds, breeding success, population density
within and amongst areas, and declines since the late 1970s.
Another chapter reviews evidence on dotterel abundance. The author
criticises a paper claiming benefits of game-keeping for moorland
birds and a report on effects of predation on birds.
National forests are required to take significant steps to
incorporate climate change in management and planning, including
the development of options that facilitate adaptation of natural
resources to potentially deleterious effects of an altered climate.
Despite uncertainties about the timing and magnitude of climate
change effects, sufficient information exists to begin the
adaptation process, a form of risk management. This book provides a
guidebook for developing adaptation options in responding to
climate change in national forests and discusses a climate project
tool as an aid for climate change adaptation.
During the Middle Sican period (C.E. 950-1050) on the North Coast
of Peru, artisans developed a sophisticated tradition of ceramic
and metalworking production amidst dry coastal forests of the
region. Organic fuel resources, specifically wood, clearly played a
vital role in the manufacture of these objects; however, this
component of production has been largely overlooked. Thus, a major
gap in our understanding of the relationship between Sican period
production and the local landscape has developed. The Sican
Archaeological Project (SAP) suggests that the production of metal
and ceramics during this period likely placed the local fuel
resources under considerable stress. Yet, an evaluation of the
archaeological data is essential to assess the degree of
overexploitation, identifying the fuels used, their contexts for
use, and their role in local ecology. This study interprets how
Middle Sican artisans met their fuel-wood requirements for
production in light of easily endangered forest resources. An
examination of the archaeological charcoal from Middle Sican period
kilns, hearths, and metal furnaces permits the reconstruction of
fuel use and the ecological setting of production. This unique site
demonstrates the concurrent production of metal and ceramics, as
well as the presence of domestic activity. Using wood anatomy of
fuels recovered from archaeological features, the author identified
the fuel materials of different use contexts.
A study of how encounters between forestry bureaucrats and
indigenous forest managers in Mexico produced official knowledge
about forests and the state. Greater knowledge and transparency are
often promoted as the keys to solving a wide array of governance
problems. In Instituting Nature, Andrew Mathews describes Mexico's
efforts over the past hundred years to manage its forests through
forestry science and biodiversity conservation. He shows that
transparent knowledge was produced not by official declarations or
scientists' expertise but by encounters between the relatively weak
forestry bureaucracy and the indigenous people who manage and own
the pine forests of Mexico. Mathews charts the performances,
collusions, complicities, and evasions that characterize the
forestry bureaucracy. He shows that the authority of forestry
officials is undermined by the tension between local realities and
national policy; officials must juggle sweeping knowledge claims
and mundane concealments, ambitious regulations and routine rule
breaking. Moving from government offices in Mexico City to forests
in the state of Oaxaca, Mathews describes how the science of
forestry and bureaucratic practices came to Oaxaca in the 1930s and
how local environmental and political contexts set the stage for
local resistance. He tells how the indigenous Zapotec people
learned the theory and practice of industrial forestry as employees
and then put these skills to use when they become the owners and
managers of the area's pine forests-eventually incorporating
forestry into their successful claims for autonomy from the state.
Despite the apparently small scale and local contexts of this
balancing act between the power of forestry regulations and the
resistance of indigenous communities, Mathews shows that it has
large implications-for how we understand the modern state,
scientific knowledge, and power and for the global carbon markets
for which Mexican forests might become valuable.
An overview of tropical rainforests for kids. Rainforests describes
tropical rainforests, why they are important, and what is happening
to them. Rainforests is based on the award-winning mongabay.com web
site. "Rainforests" includes discussion of topics including
conservation and protected areas, biodiversity and ecology,
environmental activism, sustainable development, consumption, and
economics.
The Red Hills region of south Georgia and north Florida contains
one of the most biologically diverse ecosystems in North America,
with longleaf pine trees that are up to four hundred years old and
an understory of unparalleled plant life. At first glance, the
longleaf woodlands at plantations like Greenwood, outside
Thomasville, Georgia, seem undisturbed by market economics and
human activity, but Albert G. Way contends that this environment
was socially produced and that its story adds nuance to the broader
narrative of American conservation.
The Red Hills woodlands were thought of primarily as a healthful
refuge for northern industrialists in the early twentieth century.
When notable wildlife biologist Herbert Stoddard arrived in 1924,
he began to recognize the area's ecological value. Stoddard was
with the federal government, but he drew on local knowledge to
craft his land management practices, to the point where a
distinctly southern, agrarian form of ecological conservation
emerged. This set of practices was in many respects progressive,
particularly in its approach to fire management and species
diversity, and much of it remains in effect today.
Using Stoddard as a window into this unique conservation
landscape, "Conserving Southern Longleaf" positions the Red Hills
as a valuable center for research into and understanding of
wildlife biology, fire ecology, and the environmental appreciation
of a region once dubbed simply the "pine barrens."
An overview of tropical rainforests for kids. Rainforests describes
tropical rainforests, why they are important, and what is happening
to them. Based on the award-winning mongabay.com web site. Includes
photos, charts, and maps. Note: this version is black and white;
there is also a color version.
Rain forests represent the world's richest repository of
terrestrial biodiversity, and play a major role in regulating the
global climate. They support the livelihoods of a substantial
proportion of the world's population and are the source of many
internationally traded commodities. They remain (despite decades of
conservation attention) increasingly vulnerable to degradation and
clearance, with profound though often uncertain future costs to
global society. Understanding the ecology of these diverse biomes,
and peoples' dependencies on them, is fundamental to their future
management and conservation.
Tropical Rain Forest Ecology, Diversity, and Conservation
introduces and explores what rain forests are, how they arose, what
they contain, how they function, and how humans use and impact
them. The book starts by introducing the variety of rain forest
plants, fungi, microorganisms, and animals, emphasising the
spectacular diversity that is the motivation for their
conservation. The central chapters describe the origins of rain
forest communities, the variety of rain forest formations, and
their ecology and dynamics. The challenge of explaining the species
richness of rain forest communities lies at the heart of ecological
theory, and forms a common theme throughout. The book's final
section considers historical and current interactions of humans and
rain forests. It explores biodiversity conservation as well as
livelihood security for the many communities that are dependent on
rain forests - inextricable issues that represent urgent priorities
for scientists, conservationists, and policy makers.
Forests cover approximately 30% of total land area and function as
habitats for organisms, hydrologic flow modulators, and soil
conservers, constituting one of the most important aspects of the
Earth's biosphere. The canopy is one of the uppermost levels of a
forest, below the emergent layer, formed by the tree crowns. The
canopy is home to unique flora and fauna not found in other layers
of a forest. Trees in the canopy are able to photosynthesise very
rapidly thanks to the large amount of light, so it supports the
widest diversity of plant as well as animal life in most
rainforests. This book presents a wide variety of topics on the
ecosystem in forest canopies. Included is a study on light
distribution patterns and how it effects the daily photosynthesis
of herbaceous vegetation. Recent progress, concerns, and future
directions in simulations of vegetation processes are presented as
well, in the terrestrial biosphere model that is coupled to a
climate system model.
