The Statistical Evaluation of Ecological Indicators
Ecological 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 dich...... hiện toàn bộ
Fishers' knowledge identifies environmental changes and fish abundance trends in impounded tropical rivers
Ecological 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 Low...... hiện toàn bộ
Ecotone Dynamics and Boundary Determination in the Great Dismal Swamp
Ecological 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...... hiện toàn bộ
THE HUMAN FOOTPRINT IN THE WEST: A LARGE‐SCALE ANALYSIS OF ANTHROPOGENIC IMPACTS
Ecological 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 effec...... hiện toàn bộ
IMPLEMENTING THE PRECAUTIONARY PRINCIPLE IN FISHERIES MANAGEMENT THROUGH MARINE RESERVES
Ecological Applications - Tập 8 Số sp1 - Trang S72-S78 - 1998
Tim Lauck, Colin Clark, Marc Mangel, Gordon R. Munro
DENSITY-DEPENDENT SPILLOVER FROM A MARINE RESERVE: LONG-TERM EVIDENCE
Ecological Applications - Tập 15 Số 5 - Trang 1798-1812 - 2005
Rene A. Abesamis, Garry R. Russ
Habitat damage, marine reserves, and the value of spatial management
Ecological 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 stu...... hiện toàn bộ
MARINE RESERVE BENEFITS LOCAL FISHERIES
Ecological Applications - Tập 14 Số 2 - Trang 597-606 - 2004
Garry R. Russ, Angel C. Alcala, Aileen P. Maypa, Hilconida P. Calumpong, Alan T. White
The utility of no‐take marine reserves as fisheries‐management tools is controversial. It is hypothesized that marine reserves will help to sustain fisheries external to them by becoming net exporters of adults (the “spillover effect”) and net exporters of propagules (the “recruitment effect”). Local fishery benefits from spillover will likely generate support from fishing communities for ...... hiện toàn bộ
SLIDING BASELINES, GHOSTS, AND REDUCED EXPECTATIONS IN KELP FOREST COMMUNITIES
Ecological Applications - Tập 8 Số 2 - Trang 309-322 - 1998
Paul K. Dayton, Mia J. Tegner, Peter Edwards, Kristin L. Riser
TWO CENTURIES OF MULTIPLE HUMAN IMPACTS AND SUCCESSIVE CHANGES IN A NORTH ATLANTIC FOOD WEB
Ecological Applications - Tập 14 Số 5 - Trang 1428-1447 - 2004
Heike K. Lotze, Inka Milewski
European colonization of North America severely altered terrestrial and aquatic ecosystems alike. Here, we integrate archaeological, historical, and recent data to derive the ecological history of the Quoddy Region, Bay of Fundy, Canada, an upwelling region rich in marine diversity and productivity. We document successive changes on all trophic levels from primary producers to top predator...... hiện toàn bộ
