Microbial communities and interactions in the lone star tick, Amblyomma americanum
To quantify microbial composition and interactions, we identified prokaryotic communities in the lone star tick (Amblyomma americanum) based on 16S rRNA gene sequences and direct probing. The loneExpand

Biodiversity inhibits parasites: Broad evidence for the dilution effect
Significance The dilution effect hypothesis suggests that diverse ecological communities limit disease spread via several mechanisms. Therefore, biodiversity losses could worsen epidemics that harmExpand

Infection and Co-infection Rates of Anaplasma phagocytophilum Variants, Babesia spp., Borrelia burgdorferi, and the Rickettsial Endosymbiont in Ixodes scapularis (Acari: Ixodidae) from Sites in
Abstract In total, 394 questing adult blacklegged ticks, Ixodes scapularis Say (Acari: Ixodidae), collected at four sites were analyzed by polymerase chain reaction (PCR) for five microbial species:Expand

Amphibians acquire resistance to live and dead fungus overcoming fungal immunosuppression
Emerging fungal pathogens pose a greater threat to biodiversity than any other parasitic group, causing declines of many taxa, including bats, corals, bees, snakes and amphibians. Currently, there isExpand

Parasite consumption and host interference can inhibit disease spread in dense populations.
Disease dynamics hinge on parasite transmission among hosts. However, canonical models for transmission often fit data poorly, limiting predictive ability. One solution involves building mechanisticExpand

The thermal mismatch hypothesis explains host susceptibility to an emerging infectious disease.
Parasites typically have broader thermal limits than hosts, so large performance gaps between pathogens and their cold- and warm-adapted hosts should occur at relatively warm and cold temperatures,Expand

Predator diversity, intraguild predation, and indirect effects drive parasite transmission
Significance Humans are altering biodiversity globally and infectious diseases are on the rise; thus, there is considerable interest in understanding how changes to biodiversity affect disease risk.Expand

Spatial scale modulates the strength of ecological processes driving disease distributions
Significance For four decades, ecologists have hypothesized that biotic interactions predominantly control species’ distributions at local scales, whereas abiotic factors operate more at regionalExpand

Exotic Grass Invasion Reduces Survival of Amblyomma americanum and Dermacentor variabilis Ticks (Acari: Ixodidae)
Abstract Exotic plants often invade areas of high human activity, such as along trails, roads, and forest edges, and in disturbed riparian areas. These same habitat types are also favored by ticks.Expand

Chronic contamination decreases disease spread: a Daphnia–fungus–copper case study
Chemical contamination and disease outbreaks have increased in many ecosystems. However, connecting pollution to disease spread remains difficult, in part, because contaminants can simultaneouslyExpand
