Scaling environmental change through the community‐level: a trait‐based response‐and‐effect framework for plantsGlobal Change Biology - Tập 14 Số 5 - Trang 1125-1140 - 2008

AbstractPredicting ecosystem responses to global change is a major challenge in ecology. A critical step in that challenge is to understand how changing environmental conditions influence processes across levels of ecological organization. While direct scaling from individual to ecosystem dynamics can lead to robust and mechanistic predictions, new approaches are n...... hiện toàn bộ
Bivalve aquaculture‐environment interactions in the context of climate changeGlobal Change Biology - Tập 22 Số 12 - Trang 3901-3913 - 2016
Ramón Filgueira, Thomas Guyondet, Luc A. Comeau, Réjean Tremblay
AbstractCoastal embayments are at risk of impacts by climate change drivers such as ocean warming, sea level rise and alteration in precipitation regimes. The response of the ecosystem to these drivers is highly dependent on their magnitude of change, but also on physical characteristics such as bay morphology and river discharge, which play key roles in water resi...... hiện toàn bộ
Seasonal and interannual variation in carbon dioxide exchange and carbon balance in a northern temperate grasslandGlobal Change Biology - Tập 8 Số 7 - Trang 599-615 - 2002
Lawrence B. Flanagan, Linda A. Wever, Peter J. Carlson
AbstractNet ecosystem carbon dioxide (CO2) exchange (NEE) was measured in a northern temperate grassland near Lethbridge, Alberta, Canada for three growing seasons using the eddy covariance technique. The study objectives were to document how NEE and its major component processes—gross photosynthesis (GPP) and total ecosystem respiration (TER)—...... hiện toàn bộ
Severe drought effects on ecosystem CO2 and H2O fluxes at three Mediterranean evergreen sites: revision of current hypotheses?Global Change Biology - Tập 8 Số 10 - Trang 999-1017 - 2002
Markus Reichstein, John Tenhunen, Olivier Roupsard, Jean‐Marc Ourcival, Serge Rambal, F. Miglietta, Alessandro Peressotti, Marco Pecchiari, Giampiero Tirone, Riccardo Valentini
AbstractEddy covariance and sapflow data from three Mediterranean ecosystems were analysed via top‐down approaches in conjunction with a mechanistic ecosystem gas‐exchange model to test current assumptions about drought effects on ecosystem respiration and canopy CO2/H2O exchange. The three sites include two nearly monospec...... hiện toàn bộ
Extreme temperatures, foundation species, and abrupt ecosystem change: an example from an iconic seagrass ecosystemGlobal Change Biology - Tập 21 Số 4 - Trang 1463-1474 - 2015
Jordan A. Thomson, Derek A. Burkholder, Michael R. Heithaus, James W. Fourqurean, Matthew W. Fraser, John Statton, Gary A. Kendrick
AbstractExtreme climatic events can trigger abrupt and often lasting change in ecosystems via the reduction or elimination of foundation (i.e., habitat‐forming) species. However, while the frequency/intensity of extreme events is predicted to increase under climate change, the impact of these events on many foundation species and the ecosystems they support remains...... hiện toàn bộ
Human activities as a driver of spatial variation in the trophic structure of fish communities on Pacific coral reefsGlobal Change Biology - Tập 24 Số 1 - 2018
Jonathan L. W. Ruppert, Laurent Vigliola, Michel Kulbicki, Pierre Labrosse, Marie‐Josée Fortin, Mark G. Meekan
AbstractAnthropogenic activities such as land‐use change, pollution and fishing impact the trophic structure of coral reef fishes, which can influence ecosystem health and function. Although these impacts may be ubiquitous, they are not consistent across the tropical Pacific Ocean. Using an extensive database of fish biomass sampled using underwater visual transect...... hiện toàn bộ
