Atmospheric nitrogen deposition has caused nitrogen enrichment and eutrophication of lakes in the northern hemisphere
Global Change Biology - Tập 12 Số 4 - Trang 635-643 - 2006
Ann‐Kristin Bergström, Mats Jansson
AbstractWe compiled chemical data and phytoplankton biomass (PB) data (chlorophyll a) from unproductive lakes in 42 different regions in Europe and North America, and compared these data to inorganic nitrogen (N) deposition over these regions. We demonstrate that increased deposition of inorganic N over large areas of Europe and North Ame...... hiện toàn bộ
Multimodel ensembles improve predictions of crop–environment–management interactions

AbstractA recent innovation in assessment of climate change impact on agricultural production has been to use crop multimodel ensembles (MMEs). These studies usually find large variability between individual models but that the ensemble mean (e‐mean) and median (e‐median) often seem to predict quite well...... hiện toàn bộ
Multimodel ensembles of wheat growth: many models are better than one

Stöckle, Pierre Stratonovitch, Thilo Streck, Fulu Tao, Maria Travasso, Katharina Waha, Jeffrey W. White, Heidi Webber
AbstractCrop models of crop growth are increasingly used to quantify the impact of global changes due to climate or crop management. Therefore, accuracy of simulation results is a major concern. Studies with ensembles of crop models can give valuable information about model accuracy and uncertainty, but such studies are difficult to organize and have only recently ...... hiện toàn bộ
Climate change scenarios experiments predict a future reduction in small pelagic fish recruitment in the Humboldt Current system
Global Change Biology - Tập 19 Số 6 - Trang 1841-1853 - 2013
Timothée Brochier, Vincent Échevin, Jorge Tam, Alexis Chaigneau, Katerina Goubanova, Arnaud Bertrand
AbstractThe Humboldt Current System (HCS) sustains the world′s largest small pelagic fishery. While a cooling of this system has been observed during recent decades, there is debate about the potential impacts of rising atmospheric CO2... hiện toàn bộ
Scaling up the diversity–resilience relationship with trait databases and remote sensing data: the recovery of productivity after wildfire
Global Change Biology - Tập 22 Số 4 - Trang 1421-1432 - 2016
Marko J. Spasojevic, Christie A. Bahlai, Bethany A. Bradley, Bradley J. Butterfield, Mao‐Ning Tuanmu, Seeta A. Sistla, Ruscena Wiederholt, Katharine N. Suding
AbstractUnderstanding the mechanisms underlying ecosystem resilience – why some systems have an irreversible response to disturbances while others recover – is critical for conserving biodiversity and ecosystem function in the face of global change. Despite the widespread acceptance of a positive relationship between biodiversity and resilience, empirical evidence ...... hiện toàn bộ
Scaling environmental change through the community‐level: a trait‐based response‐and‐effect framework for plants
Global Change Biology - Tập 14 Số 5 - Trang 1125-1140 - 2008
Katharine N. Suding, Sandra Lavorel, F. Stuart Chapin, Johannes H. C. Cornelissen, Sandra Dı́az, Éric Garnier, Deborah E. Goldberg, David U. Hooper, Stephen T. Jackson, Marie‐Laure Navas
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 change
Global 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 grassland
Global 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
Temperature controls ecosystem CO2 exchange of an alpine meadow on the northeastern Tibetan Plateau
Global Change Biology - Tập 15 Số 1 - Trang 221-228 - 2009
Makoto Saito, Tomomichi Kato, Yanhong Tang
AbstractAlpine ecosystems are extremely vulnerable to climate change. To address the potential variability of the responses of alpine ecosystems to climate change, we examined daily CO2 exchange in relation to major environmental variables. A dataset was obtained from an alpine meadow on the Qinghai‐Tibetan Plateau from eddy covariance measurem...... hiện toàn bộ
