    Simplifying biological complexity

    There are huge and growing opportunities for fruitful interactions between physicists and biologists. Understanding how key components of a biological system interact across organizational levels is a major ch...

    Why large-scale climate indices seem to predict ecological processes better than local weather

    Large-scale climatic indices such as the North Atlantic Oscillation1 are associated with population dynamics2, variation in demographic rates3 and values of phenotypic traits4,5 in many species. Paradoxically, th...

    Ecological interference between fatal diseases

    An important issue in population biology is the dynamic interaction between pathogens. Interest has focused mainly on the indirect interaction of pathogen strains, mediated by cross immunity1,2,3,4. However, a me...

    Modelling vaccination strategies against foot-and-mouth disease

    Vaccination has proved a powerful defence against a range of infectious diseases of humans and animals. However, its potential to control major epidemics of foot-and-mouth disease (FMD) in livestock is content...

    Travelling waves and spatial hierarchies in measles epidemics

    Spatio-temporal travelling waves are striking manifestations of predator–prey and host–parasite dynamics. However, few systems are well enough documented both to detect repeated waves and to explain their inte...

    reply: Nonlinearity and the Moran effect

    Grenfell et al. reply — The Moran effect refers to systems of population dynamics that are linear: under these circumstances, the long-term correlation between population densities will be the same as the correla...

    Noise and determinism in synchronized sheep dynamics

    A major debate in ecology concerns the relative importance of intrinsic factors and extrinsic environmental variations in determining population size fluctuations1,2,3,4,5,6. Spatial correlation of fluctuations i...

    Overcompensation and population cycles in an ungulate

    ALTHOUGH theoretical studies show that overcompensatory density-dependent mechanisms can potentially generate regular or chaotic fluctuations in animal numbers, the majority of realistic single-species models ...
