The Statistical Evaluation of Ecological IndicatorsEcological Applications - Tập 6 Số 1 - Trang 132-139 - 1996
Paul A. Murtaugh
Ecological indicators are easily measured surrogates for underlying properties
or responses of a system that are difficult to measure accurately and reliably.
Methods from signal detection theory can be used to assess the usefulness of
such indicators, based on pilot data sets in which some gold standard of the
underlying response has been measured. For responses that can naturally be
dichotomized... hiện toàn bộ
Spatial processes structuring riparian plant communities in agroecosystems: implications for restorationEcological Applications - Tập 26 Số 7 - Trang 2103-2115 - 2016
Bérenger Bourgeois, Eduardo González, Anne Vanasse, Isabelle Aubin, Monique Poulin
AbstractThe disruption of hydrological connectivity by human activities such as
flood regulation or land‐use changes strongly impacts riparian plant
communities. However, landscape‐scale processes have generally been neglected in
riparian restoration projects as opposed to local conditions, even though such
processes might largely influence community recovery. We surveyed plant
composition of fiel... hiện toàn bộ
Fishers' knowledge identifies environmental changes and fish abundance trends in impounded tropical riversEcological Applications - Tập 23 Số 2 - Trang 392-407 - 2013
Gustavo Hallwass, Priscila F. M. Lopes, Anastácio A. Juras, Renato Azevedo Matias Silvano
The long‐term impacts of large hydroelectric dams on small‐scale fisheries in
tropical rivers are poorly known. A promising way to investigate such impacts is
to compare and integrate the local ecological knowledge (LEK) of resource users
with biological data for the same region. We analyzed the accuracy of fishers'
LEK to investigate fisheries dynamics and environmental changes in the Lower

Ecotone Dynamics and Boundary Determination in the Great Dismal SwampEcological Applications - Tập 4 Số 1 - Trang 189-203 - 1994
Virginia Carter, Patricia T. Gammon, Mary Keith Garrett
Data on hydrogeology, soils, and vegetation collected on four transects across
the 48—km wetland—to—upland transition zone of the Great Dismal Swamp of
Virginia/North Carolina, USA, were used to analyze changes along the
moisture/elevation gradient, to characterize the wetland—upland ecotone, and to
select tentative wetland—upland boundaries based on these three parameters.
Transition zone vegetat... hiện toàn bộ
THE HUMAN FOOTPRINT IN THE WEST: A LARGE‐SCALE ANALYSIS OF ANTHROPOGENIC IMPACTSEcological Applications - Tập 18 Số 5 - Trang 1119-1139 - 2008
Matthias Leu, Steven E. Hanser, Steven T. Knick
Anthropogenic features such as urbanization, roads, and power lines, are
increasing in western United States landscapes in response to rapidly growing
human populations. However, their spatial effects have not been evaluated. Our
goal was to model the human footprint across the western United States. We first
delineated the actual area occupied by anthropogenic features, the physical
effect area. ... hiện toàn bộ

Habitat damage, marine reserves, and the value of spatial managementEcological Applications - Tập 23 Số 5 - Trang 959-971 - 2013
Holly V. Moeller, Michael G. Neubert
The biological benefits of marine reserves have garnered favor in the
conservation community, but “no‐take” reserve implementation is complicated by
the economic interests of fishery stakeholders. There are now a number of
studies examining the conditions under which marine reserves can provide both
economic and ecological benefits. A potentially important reality of fishing
that these studies ove... hiện toàn bộ
