Sand lizards (Lacerta agilis) decrease nymphal infection prevalence for tick-borne pathogens Borrelia burgdorferi sensu lato and Anaplasma phagocytophilum in a coastal dune ecosystem
<p>1. Understanding which factors determine tick-borne disease hazard can contribute to effective disease control. In Europe, the hazard of the pathogens <em>Borrelia burgdorferi</em> s.l. and <em>Anaplasma phagocytophilum</em> is determined by local tick densities (mainly <em>Ixodes ricinus</em>) and the reservoir competence of the host species community. Sand lizards (<em>Lacerta agilis</em>) are common hosts for larvae and nymphs of <em>I. ricinus</em> and non-competent reservoirs for both pathogens. Consequently, high relative abundance of <em>L. agilis</em> is hypothesized to be associated with lower infection prevalence in nymphs. Here, we aimed to test whether this effectively occurs in natural settings.</p> <p>2. We sampled different habitat types within a heterogenous dune landscape at the Dutch coast and estimated 1) <em>L. agilis</em> densities, 2) host community competence, 3) the density and infection prevalence of questing<em> I. ricinus</em> ticks, and 4) the number and infection prevalence of ticks feeding on <em>L. agilis</em>.</p> <p>3. Captured <em>L. agilis</em> had high tick burdens and contributed substantially to feeding <em>I. ricinus</em> larvae in their natural habitat. <em>B. burgdorferi</em> s.l. and <em>A. phagocytophilum</em> were virtually absent from feeding larvae and nymphs.</p> <p>4. The nymphal infection prevalence of both pathogens in questing ticks was lower in habitat types where <em>L. agilis</em> was more abundant. Hence, <em>L. agilis</em> strongly reduced community competence.</p> <p>5. The density of questing nymphs was higher in habitat types with denser vegetation and also varied more between habitat types than infection prevalence. As a result, nymphal density had a stronger effect on the density of infected ticks than did nymphal infection prevalence.</p> <p>6. Synthesis and applications. Coastal dune habitats favourable for <em>L. agilis</em> have lower densities of questing nymphs, and a lower human infection hazard. These results might be applicable to similar ecosystems where <em>L. agilis</em> is present. From a public health perspective, this underlines the importance of preserving early successional habitat, as encroaching shrubs are associated with higher tick-borne disease hazard, and vegetation removal might be a solution to reduce hazard in coastal dunes. The high degree of spatial heterogeneity in the abundance of tick-borne pathogens also poses opportunities to manage recreational activities to limit human exposure to tick-borne diseases.</p>

Data from: Geographic variation of life-history traits in the sand lizard, Lacerta agilis: testing Darwin's fecundity-advantage hypothesis
The fecundity-advantage-hypothesis (FAH) explains larger female size relative to male size as a correlated response to fecundity selection. We explored FAH by investigating geographic variation in female reproductive output and its relation to sexual size dimorphism (SSD) in Lacerta agilis, an oviparous lizard occupying a major part of temperate Eurasia. We analysed how sex-specific body size and SSD are associated with two putative indicators of fecundity selection intensity (clutch size and the slope of the clutch size-female size relationship), and with two climatic variables throughout the species range and across two widespread evolutionary lineages. Variation within the lineages provides no support for FAH. In contrast, the divergence between the lineages is in line with FAH: the lineage with consistently female-biased SSD (L. a. agilis) exhibits higher clutch size and steeper fecundity slope than the lineage with an inconsistent and variable SSD (L. a. exigua). L. a. agilis shows lower offspring size (egg mass, hatchling mass) and higher clutch mass relative to female mass than L. a. exigua, i.e. both possible ways to enhance offspring number are exerted. As the SSD difference is due to male size (smaller males in L. a. agilis), fecundity selection favouring larger females, together with viability selection for smaller size in both sexes, would explain the female-biased SSD and reproductive characteristics of L. a. agilis. The pattern of intraspecific life-history divergence in L.agilis is strikingly similar to that between oviparous and viviparous populations of a related species Zootoca vivipara. Evolutionary implications of this parallelism are discussed.
