A review of methods for the assessment of prediction errors in conservation presence/absence models Tập 24 Số 1 - Trang 38-49 - 1997
Alan H. Fielding, James P. Bell
Predicting the distribution of endangered species from habitat data is
frequently perceived to be a useful technique. Models that predict the presence
or absence of a species are normally judged by the number of prediction errors.
These may be of two types: false positives and false negatives. Many of the
prediction errors can be traced to ecological processes such as unsaturated
habitat and speci... hiện toàn bộ
Environmental threats and environmental future of estuaries Tập 29 Số 1 - Trang 78-107 - 2002
Michael J. Kennish
Estuaries exhibit a wide array of human impacts that can compromise their
ecological integrity, because of rapid population growth and uncontrolled
development in many coastal regions worldwide. Long-term environmental problems
plaguing estuaries require remedial actions to improve the viability and health
of these valuable coastal systems. Detailed examination of the effects of
pollution inputs, ... hiện toàn bộ
Threats to the running water ecosystems of the world Tập 29 Số 2 - Trang 134-153 - 2002
Björn Malmqvist, Simon D. Rundle
Running waters are perhaps the most impacted ecosystem on the planet as they
have been the focus for human settlement and are heavily exploited for water
supplies, irrigation, electricity generation, and waste disposal. Lotic systems
also have an intimate contact with their catchments and so land-use alterations
affect them directly. Here long-term trends in the factors that currently impact
runni... hiện toàn bộ
Moving beyond panaceas: a multi-tiered diagnostic approach for social-ecological analysis Tập 37 Số 4 - Trang 451-463 - 2010
Элинор Остром, Michael Cox
SUMMARYDisturbances to key aspects of ecological systems, including biodiversity
loss, climate change, pollution and natural resource degradation, have become a
major concern to many policy analysts. Instead of learning from the study of
biological complexity however, social scientists tend to recommend simple
panaceas, particularly government or private ownership, as ‘the’ way to solve
these prob... hiện toàn bộ
Applying the ecosystem services concept to poverty alleviation: the need to disaggregate human well-being Tập 38 Số 4 - Trang 370-379 - 2011
Tim M. Daw, Katrina Brown, Sérgio Rosendo, Robert S. Pomeroy
SUMMARYThe concept of ecosystem services (ES), the benefits humans derive from
ecosystems, is increasingly applied to environmental conservation, human
well-being and poverty alleviation, and to inform the development of
interventions. Payments for ecosystem services (PES) implicitly recognize the
unequal distribution of the costs and benefits of maintaining ES, through
monetary compensation from ... hiện toàn bộ
Saltmarshes in a time of change Tập 29 Số 1 - Trang 39-61 - 2002
Paul Adam
Saltmarshes are a major, widely distributed, intertidal habitat. They are
dynamic systems, responding to changing environmental conditions. For centuries,
saltmarshes have been subject to modification or destruction because of human
activity. In this review, the range of factors influencing the survival of
saltmarshes is discussed. Of critical importance are changes in relative sea
level and in ti... hiện toàn bộ
Sustainability science: a review, an analysis and some empirical lessons Tập 38 Số 3 - Trang 275-287 - 2011
Joachim H. Spangenberg
SUMMARYSustainability science has developed from a new research field into a
vibrant discipline in its own right, with scientific conferences, journals and
scientific societies dedicated to its pursuit. Characterized more by its
research purpose than by a common set of methods or objects, sustainability
science can be subdivided into the more traditional disciplinary-based science
for sustainabili... hiện toàn bộ
