A model-data comparison of gross primary productivity: Results from the North American Carbon Program site synthesis
Download2012
Anderson, R., Poulter, B., Matamala, R., Lokipitiya, E., Chen, J.M., Verbeeck, H., Davis, K.J., Weng, E., Curtis, P.S., Tonitto, C., Munger, J.W., Ricciuto, D., Chen, J., Gu, L., Humphreys, E., Desai, A.R., Price, D.T., Raczka, B.M., Zhou, X., Peng, C., Torn, M., Hollinger, D.Y., Riley, W.J., Roulet, N., Black, A., Bolstad, P., Baker, I., Thornton, P., Monson, R., Jain, A., Law, B., Gough, C., Margolis, H.A., Dimitrov, D., Grant, R.F., Liu, S., McCaughey, J.H., Hilton, T.W., Sahoo, A., Dietze, M., Schaefer, K., Williams, C., Dragoni, D., Tian, H., Vargas, R., Schwalm, C.R., Richardson, A.D., Oechel, W., Kucharik, C., Barr, A., Altaf Arain, M.
Accurately simulating gross primary productivity (GPP) in terrestrial ecosystem models is critical because errors in simulated GPP propagate through the model to introduce additional errors in simulated biomass and other fluxes. We evaluated simulated, daily average GPP from 26 models against...

Accessibility in Questionnaire Research: Integrating Universal Design to Increase the Participation of Individuals With Learning Disabilities
Download2018-01-01
Goegan, Lauren D, Radil, Amanda I, Daniels, Lia M
This paper explores how to apply the principles of accommodations and universal design (UD) in research methods involved in quantitative research (e.g. questionnaires). In particular, we focus on how to make research more accessible for individuals with Learning Disabilities (LD), while also...

Ecological controls on net ecosystem productivity of a mesic arctic tundra under current and future climates
Download2011
Dimitrov, D. D., Grant, R. F., Lafleur, P. M., Humphreys, E. R.
Abstract: Changes in arctic C stocks with climate are thought to be caused by rising net primary productivity (NPP) during longer and warmer growing seasons, offset by rising heterotrophic respiration (Rh) in warmer and deeper soil active layers. In this study, we used the process model ecosys to...

Spring 2012
Background: Striking a balance between work and family care is a challenge for families today. More than 200,000 families in Canada have the additional demands that come with caring for a child with disability including implementing therapist-recommended goals and home programs. Aim: Underpinned...

Modeling the carbon balance of Amazonian rain forests: resolving ecological controls on net ecosystem productivity
Download2009
de Oliveira, R. C., Munger, J. W., Wofsy, S. C., Hutra, L. R., Grant, R. F., Saleska, S. R.
Abstract: There is still much uncertainty about ecological controls on the rate and direction of net CO(2) exchange by tropical rain forests, in spite of their importance to global C cycling. These controls are thought to arise from hydrologic and nutrient constraints to CO(2) fixation caused by...

Modeling the effects of hydrology on gross primary productivity and net ecosystem productivity at Mer Bleue bog
Download2011
Humphreys, E., Dimitrov, D. D., Grant, R. F., LaFleur, P. M.
Abstract: The ecosys model was applied to investigate the effects of water table and subsurface hydrology changes on carbon dioxide exchange at the ombrotrophic Mer Bleue peatland, Ontario, Canada. It was hypothesized that (1) water table drawdown would not affect vascular canopy water potential,...

Modelling water table depth effects on net ecosystem CO2 exchange of two contrasting forested peatlands – a tropical bog and a boreal fen
DownloadFall 2015
Peatlands have been accumulating carbon (C) in wet soils under shallow water table (WT) over millennia. Increased frequency and intensity of droughts and artificial drainage for promoting agriculture have recently been causing peatland WT depth (WTD) drawdown. This could alter peatland C balance...
