A Quantitative Model of Honey Bee Colony Population Dynamics
Since 2006 the rate of honey bee colony failure has increased significantly. As an aid to testing hypotheses for the causes of colony failure we have developed a compartment model of honey bee colonyExpand

Honey Bee Nest Thermoregulation: Diversity Promotes Stability
A honey bee colony is characterized by high genetic diversity among its workers, generated by high levels of multiple mating by its queen. Few clear benefits of this genetic diversity are known. HereExpand

Rapid behavioral maturation accelerates failure of stressed honey bee colonies
Significance Honey bee colony death rates are unsustainably high. While many stressors have been identified that contribute to this problem, we do not know why colonies transition so rapidly from aExpand

Spatio-temporal patterns generated by Salmonella typhimurium.
We present experimental results on the bacterium Salmonella typhimurium which show that cells of chemotactic strains aggregate in response to gradients of amino acids, attractants that theyExpand

Modelling Food and Population Dynamics in Honey Bee Colonies
Honey bees (Apis mellifera) are increasingly in demand as pollinators for various key agricultural food crops, but globally honey bee populations are in decline, and honey bee colony failure ratesExpand

Simulation models of the role of genetic variability in social insect task allocation
SummaryA feature of some species of eusocial Hymenoptera is a high level of intra-colonial genetic diversity, and correlated diversity in the level of the stimulus required for individuals toExpand

Bifurcating spatially heterogeneous solutions in a chemotaxis model for biological pattern generation.
We consider a simple cell-chemotaxis model for spatial pattern formation on two-dimensional domains proposed by Oster and Murray (1989, J. exp. Zool. 251, 186-202). We determine finite-amplitude,Expand

Studies in vitro on the relative efficacy of current acaricides for Sarcoptes scabiei var. hominis.
Resistance of Sarcoptes scabiei to various topical therapies has been described, but clinical assessment of treatment failure is problematic and in-vitro assays are generally not available. WeExpand

Pigmentation pattern formation on snakes.
We consider a cell-chemotaxis model mechanism for generating some of the common, simple and complex, patterns found on the skin of snakes. By investigating the pattern generation potential of theExpand

An ODE Model of Early Stages of Atherosclerosis: Mechanisms of the Inflammatory Response
Atherosclerosis is a chronic disease of the large arteries, characterized by fatty cholesterol-filled streaks and plaque build-up within the artery wall. Within the past decade, inflammation has beenExpand
