Distribution of ticks, tick-borne pathogens and the associated local environmental factors including small mammals and livestock, in two French agricultural sites: the OSCAR database
A database on the distribution and densities of I. ricinus ticks - the most common tick species in French agricultural landscapes - and the prevalence of three tick-borne pathogens (Anaplasma phagocytophilum, Borrelia spp.) in two sites in north-western and south-western France is reported. Expand
Questing tick abundance in urban and peri-urban parks in the French city of Lyon
This study confirmed the presence of ticks in all of the parks surveyed, although their occurrence in the urban parks was very rare compared to the peri-urban park and the control site. Expand

Detection of Wolbachia in the Tick Ixodes ricinus is Due to the Presence of the Hymenoptera Endoparasitoid Ixodiphagus hookeri
The endoparasitoid wasp Ixodiphagus hookeri is infested at almost 100% prevalence by a W. pipientis strain belonging to a Wolbachia supergroup that has already been reported as associated with other hymenopteran parasitoids, and the consequences of this finding for the understanding of the tick microbiome, and their possible role in horizontal gene transfer among pathogenic and symbiotic bacteria.

Simulation of climate–host–parasite–landscape interactions: A spatially explicit model for ticks (Acari: Ixodidae)
A spatially explicit, individual-/agent-based, stochastic model that can simulate the spatial-temporal dynamics of ticks in response to changes in climatic conditions, landscape structure, and host community composition is developed and should prove useful in exploring the role of host community characteristics in the maintenance of tick populations.

A modified matrix model to describe the seasonal population ecology of the European tick Ixodes ricinus
Modelling the tick’s complex seasonal dynamics underpins the analysis of tick-borne disease risk and potential tick control, and can be used to evaluate public health risk, tick management strategies and potential effects of future environmental change. Expand
A population model to describe the distribution and seasonal dynamics of the tick Hyalomma marginatum in the Mediterranean Basin.
A dynamic population model of Hyalomma marginatum, the vector of several pathogens in the western Palearctic, was developed to simulate effects of temperature and water vapour deficit (VD) on tick survival, development rates and seasonality, implying that under current climate conditions, there is no potential to spread at the spatial scale of the model.

Modelling the effect of temperature variation on the seasonal dynamics of Ixodes ricinus tick populations.
The effect of changing patterns of temperature variation on the dynamics of I. ricinus ticks and the diseases they transmit may depend on the cumulative temperature over the year and will therefore vary across different locations. Expand
Modelling the effects of recent changes in climate, host density and acaricide treatments on population dynamics of Ixodes ricinus in the UK
Summary 1. A population model for the tick Ixodes ricinus, the most significant vector of pathogens in Europe, is used to explore the relative impact of changes in climate, host density andExpand
Reproducibility of local environmental factors for the abundance of questing Ixodes ricinus nymphs on pastures.
The study confirmed the status of key factors for nymph abundance while avoiding having to redefine the statistical model to model the different sampling conditions and shows the difficulty to identify factors with general significance acting on a very variable phenomenon. Expand
Influence of host migration between woodland and pasture on the population dynamics of the tick Ixodes ricinus: A modelling approach
A dynamic model to simulate changes in tick density at different stages (egg, larva, nymph and adult) under the influence of temperature is developed and demonstrated that demographic parameters played a crucial role in the determination of questing nymph densities. Expand
Introduced Siberian chipmunks are more heavily infested by ixodid ticks than are native bank voles in a suburban forest in France.
The higher tick loads, and more specifically the ratio of nymphs over larvae, observed in chipmunks may be caused by a higher predisposition--both in terms of susceptibility and exposure--to questing ticks. Expand
Invasive honeysuckle eradication reduces tick-borne disease risk by altering host dynamics
It is demonstrated that a widespread invasive shrub in North America, Amur honeysuckle, increases human risk of exposure to ehrlichiosis, an emerging infectious disease caused by bacterial pathogens transmitted by the lone star tick, and suggested that management of biological invasions may help ameliorate the burden of vector-borne diseases on human health.
