 Threshold dynamics for periodically forced ecological systems: the control of population invasion and exclusionJ V Greenman
Computing Science and Mathematics, University of Stirling, Stirling, Scotland, UK
J Theor Biol 295:15467. 2012..We apply this methodology to look at three important issues, involving the relationships between resonance and control, between vaccination policy and the stage structure of a disease and between apparent competition and coexistence...  The exclusion problem in seasonally forced epidemiological systemsJ V Greenman
Computing Science and Mathematics, University of Stirling, Stirling FK9 4LA, Scotland, UK Electronic address
J Theor Biol 367:4960. 2015..Onoff control switching, resonant amplification, optimality and controllability are important issues that emerge in the discussion. ..  Phase control of resonant systems: interference, chaos and high periodicityJ V Greenman
Department of Computing Science and Mathematics, University of Stirling, Stirling FK94LA, Scotland, UK
J Theor Biol 278:7486. 2011..The effect of noise as a source of high period fluctuations is also considered...  Pathogen exclusion from ecoepidemiological systemsJ V Greenman
Department of Computing Science and Mathematics, University of Stirling, Stirling FK9 4LA, Scotland, United Kingdom
Am Nat 176:14958. 2010..This distortion is highly sensitive to the lags between forcing components, a sensitivity that can be exploited by management using correctly lagged cyclically varying controls to reduce the effort involved in pathogen exclusion...  Exclusion of generalist pathogens in multihost communitiesJ V Greenman
Department of Computing Science and Mathematics, University of Stirling, Stirling FK9 4LA, Scotland, United Kingdom
Am Nat 172:57684. 2008..In particular, we show that the introduction of an additional host can eliminate the pathogen rather than eliminate the resident host. The discussion is illustrated with a reference to bovine tuberculosis...  Environmental forcing, invasion and control of ecological and epidemiological systemsJ V Greenman
Department of Computing Science and Mathematics, University of Stirling, Stirling FK9 4LA, Scotland, UK
J Theor Biol 247:492506. 2007..The general theory is illustrated by a range of models drawn from ecology and epidemiology. The relationship between periodic and stochastic forcing is also considered...  The impact of environmental fluctuations on structured discrete time population models: resonance, synchrony and threshold behaviourJ V Greenman
Department of Computing Science and Mathematics, University of Stirling, Stirling, FK9 4LA, Scotland, UK
Theor Popul Biol 68:21735. 2005..The implications of external forcing for stagestructured species, for populations in competition and for trophic web systems are studied using the tools and concepts developed in the paper...  The evolution of oscillatory behavior in agestructured speciesJ V Greenman
Department of Computing Science and Mathematics, University of Stirling, Stirling FK9 4LA, Scotland, United Kingdom
Am Nat 166:6878. 2005..The robustness of this result to variations in tradeoff function and density dependence is tested...  Large amplification in stagestructured models: Arnol'd tongues revisitedJ V Greenman
Department of Computing Science and Mathematics, University of Stirling, Stirling, FK9 4LA, Scotland
J Math Biol 48:64771. 2004..This paper is a contribution to that continuing debate...  The amplification of environmental noise in population models: causes and consequencesJ V Greenman
Department of Computing Science and Mathematics, University of Stirling, Stirling FK9 4LA, Scotland
Am Nat 161:22539. 2003..The sensitivity of the population dynamics to noise when close to a bifurcation has wideranging consequences for the evolution and ecology of population dynamics...  Parasitemediated and direct competition in a twohost shared macroparasite systemJ V Greenman
Stirling Mathematical Ecology Group, Department of Computing Science and Mathematics, University of Stirling, Stirling, FK9 4LA, Scotland
Theor Popul Biol 57:1334. 2000..They are therefore as relevant to the analysis of such general issues as exploitative competition and trophic interactions as they are to specific epidemiological problems...  Multihost, multiparasite systems: an application of bifurcation theoryJ V Greenman
Department of Computing Science and Mathematics, University of Stirling, Scotland, UK
IMA J Math Appl Med Biol 16:33367. 1999....  Host exclusion and coexistence in apparent and direct competition: An application of bifurcation theoryJ V Greenman
Stirling Mathematical Ecology Group, University of Stirling, Stirling, FK9 4LA, Scotland
Theor Popul Biol 56:4864. 1999..Two field phenomena of particular interest, discussed in the paper, are host invasion and dominance reversal resulting from the introduction of the pathogen into a directly competitive system...  The effect of seasonal host birth rates on population dynamics: the importance of resonanceJ M Ireland
Department of Computing Science and Mathematics, University of Stirling, Stirling, Scotland FK9 4LA, UK
J Theor Biol 231:22938. 2004..We then look at whether many biological systems are likely to display these "resonant" dynamics and find that we would expect them to be widespread...  Differential impact of a shared nematode parasite on two gamebird hosts: implications for apparent competitionD M Tompkins
Department of Biological Sciences, University of Stirling, UK
Parasitology 122:18793. 2001..If this is the case, the associated decrease in the force of infection to which the partridge is exposed may be sufficient to change the model prediction from partridge exclusion to pheasant and partridge coexistence...
