Sperling, F. A. H., MacQuarrie, C. J. K., Langor, D. W.
Mitochondrial cytochrome oxidase I and 11 genes were sequenced for two invasive alien birch (Betula L. [Betulaceae]) leaf-mining sawflies, Profenusa thomsoni (Konow, 1886) (Hymenoptera: Tenthredinidae) and Scolioneura betuleti (King, 1816) (Hymenoptera: Tenthredinidae), accidentally introduced...

Modeling group formation and activity patterns in self-organizing collectives of individuals
Download2007-01-01
Eftimie, R., Lewis, Mark A., Lutscher, F., de Vries, G.
We construct and analyze a nonlocal continuum model for group formation with application to self-organizing collectives of animals in homogeneous environments. The model consists of a hyperbolic system of conservation laws, describing individual movement as a correlated random walk. The turning...

MacIsaac, H.J., Lewis, Mark A., Robbins, T.C.
The spread of nonindigenous species in aquatic ecosystems provides an opportunity to develop new perspectives on the invasion process. In this paper we review existing invasion models, most of which were developed to describe invasions of terrestrial habitats, and propose an alternative that...

Nathan G. Marculis, Maya L. Evenden, Mark A. Lewis
Trade-offs between dispersal and reproduction are known to be important drivers of population dynamics, but their direct influence on the spreading speed of a population is not well understood. Using integrodifference equations, we develop a model that incorporates a dispersal–reproduction...

Modeling the early transmission of COVID-19 in New York and San Francisco using a pairwise network model
Download2022-01-01
Shanshan Feng, Xiao-Feng Luo, Xin Pei, Zhen Jin, Mark Lewis, Hao Wang
Classical epidemiological models assume mass action. However, this assumption is violated when interactions are not random. With the recent COVID-19 pandemic, and resulting shelter in place social distancing directives, mass action models must be modified to account for limited social...

Modelling long- term impacts of mountain pine beetle outbreaks on merchantable biomass, ecosystem carbon, albedo, and radiative forcing
Download2016-01-01
Price, David T., Matthews, H. Damon, Parrott, Lael, Ramankutty, Navin, Landry, Jean-Sébastien
The ongoing major outbreak of mountain pine beetle (MPB) in forests of western North America has led to considerable research efforts. However, many questions remain unaddressed regarding its long-term impacts, especially when accounting for the range of possible responses from the non-target...

Jody R. Reimer, Marc Mangel, Andrew E. Derocher, Mark A. Lewis
Animals must balance a series of costs and benefits while trying to maximize their fitness. For example, an individual may need to choose how much energy to allocate to reproduction versus growth, or how much time to spend on vigilance versus foraging. Their decisions depend on complex...

Modelling the spread of the invasive alga Codium fragile driven by long-distance dispersal of buoyant propagules
Download2015-10-21
The secondary spread of an invasive species after initial establishment is a major factor in determining its distribution and impacts. Determining and understanding the factors driving this secondary spread is therefore of great importance to manage and predict invasions. In this study we...
