Spatiotemporal integration of molecular and anatomical data in virtual reality using semantic mapping
Download2009
Janzen, R.P., Dong, X., Gordon, P.M., Soh, J., Wishart, D.S., Sabhaney, A., Turinsky, A.L., Sensen, C.W., Chang, J., Hau, D., Xia, J., Trinh, Q.M.
We have developed a computational framework for spatiotemporal integration of molecular and anatomical datasets in a virtual reality environment. Using two case studies involving gene expression data and pharmacokinetic data, respectively, we demonstrate how existing knowledge bases for molecular...

Specific detection of Campylobacter jejuni using the bacteriophage NCTC 12673 receptor binding protein as a probe
Download2011
Szymanski, Christine M., Arutyunov, Denis, McDermott, Mark T., Evoy, Stephane, Singh, Amit
Campylobacter jejuni is found in the intestines of poultry, cattle, swine, wild birds and pet animals and is the major cause of foodborne gastroenteritis in developed countries. We report the use of the receptor binding protein (RBP) of Campylobacter bacteriophage NCTC 12673 for the specific...

Speirseopteris orbiculata gen. et sp. nov. (Thelypteridaceae), a derived fossil filicalean from the Paleocene of western North America.
Download2006
Stockey, R.A., Rothwell, G.W., Lantz, T.C.
An apparently exindusiate filicalean fern with radial sori, sporangia with a vertical annulus, and monolete spores occurs in Paleocene sediments ca. 57 million years old of central Alberta, Canada. Specimens are preserved as coalified compressions and show features of frond morphology and...

Sponges perceive and respond to a range of stimuli. How they do this is still difficult to pin down despite now having transcriptomes and genomes of an array of species. Here we evaluate the current understanding of sponge behavior and present new observations on sponge activity in situ. We also...

One crucial measure of a species' invasiveness is the rate at which it spreads into a competitor's environment. A heuristic spread rate formula for a spatially explicit, two-species competition model relies on `linear determinacy' which equates spread rate in the full nonlinear model with spread...

Chronic wasting disease (CWD) is a fatal disease of cervid species that continues to spread across North America and now in Europe. It poses a threat to cervid populations and the local ecological and economic communities that depend on them. Although empirical studies have shown that host home...

State-space models link elk movement patterns to landscape characteristics in Yellowstone National Park
Download2007
Smith, D. W., Anderson, D. P., Ives, A. R., Turner, M. G., Beyer, H. L., Boyce, M. S., Forester, J. D., Fortin, D.
Explaining and predicting animal movement in heterogeneous landscapes remains challenging. This is in part because movement paths often include a series of short, localized displacements separated by longer-distance forays. This multiphasic movement behavior reflects the complex response of an...

State-space models' dirty little secrets: Even simple linear Gaussian models can have parameter and state estimation problems
Download2016-01-01
Auger-Méthé, Marie, Field, Chris, Albertsen, Christopher M., Derocher, Andrew E., Lewis, Mark A., Jonsen, Ian D., Mills Flemming, Joanna
State-space models (SSMs) are increasingly used in ecology to model time-series such as animal movement paths and population dynamics. This type of hierarchical model is often structured to account for two levels of variability: biological stochasticity and measurement error. SSMs are flexible....

Step selection techniques uncover the environmental predictors of space use patterns in flocks of Amazonian birds
Download2014-01-01
Potts, Jonathan R., Mokross, Karl, Stouffer, Philip C., Lewis, Mark A.
Understanding the behavioral decisions behind animal movement and space use patterns is a key challenge for behavioral ecology. Tools to quantify these patterns from movement and animal–habitat interactions are vital for transforming ecology into a predictive science. This is particularly...

Freshwater aquatic systems in North America are being invaded by many different species, ranging from fish, mollusks, cladocerans to various bacteria and viruses. These invasions have serious ecological and economic impacts. Human activities such as recreational boating are an important pathway...
