A key problem in environmental flow assessment is the explicit linking of the flow regime with ecological dynamics. We present a hybrid modeling approach to couple hydrodynamic and biological processes, focusing on the combined impact of spatial heterogeneity and temporal variability on...

Second-generation stoichiometric mathematical model to predict methane emissions from oil sands tailings
Download2019-07-31
Jude D. Kong, Hao Wang, Tariq Siddique, Julia Foght, Kathleen Semple, Zvonko Burkus, Mark A. Lewis
Microbial metabolism of fugitive hydrocarbons produces greenhouse gas (GHG) emissions from oil sands tailings ponds (OSTP) and end pit lakes (EPL) that retain fluid tailings from surface mining of oil sands ores. Predicting GHG production, particularly methane (CH4), would help oil sands...

Habitat protection has been identified as an important strategy for the conservation of woodland caribou (Rangifer tarandus). However, because of the economic opportunity costs associated with protection it is unlikely that all caribou ranges can be protected in their entirety. We used an...

Separable whorl-specific expression and negative regulation by enhancer elements within the AGAMOUS second intron
Download2000
Deyholos, M. K., Sieburth, L. E.
We analyzed the 4-kb intragenic control region of the AGAMOUS (AG) gene to gain insight into the mechanisms controlling its expression during early flower development. We identified three major expression patterns conferred by 19 AG::reporter gene constructs: the normal AG pattern, a...

Separate effects of human visitation and touch on plant growth and herbivory in an old-field community

Cahill, J. F., Castelli, J. P., Casper, B. B.
Although animal scientists have long been aware that methods used to measure an experimental system can affect the subject of measurement, similar confounding effects of commonly used field methods have only recently been acknowledged by plant ecologists. Here we demonstrate significant effects...

States, J.C., Zhao, H-Z., Aiken, J.M., McKenzie, D.I., Dixon, G.H.
We have sequenced five different rainbow trout protamine genes plus their flanking regions. The genes are not clustered and do not contain intervening sequences. There is an extremely high degree of sequence conservation in the coding and 3' untranslated regions of the gene. Downstream sequences...

Sequential decision-making in a variable environment: modeling elk movement in Yellowstone National Park as a dynamic game.
Download2007
Potapov, A. B., Noonburg, E. G., Newman, L. A., Lewis, M. A., Crabtree, R. L.
We develop a suite of models with varying complexity to predict elk movement behavior during the winter on the Northern Range of Yellowstone National Park (YNP). The models range from a simple representation of optimal patch choice to a dynamic game, and we show how the underlying theory in each...
