Study finds diversity cuts Lyme

Researchers at the Cary Institute of Ecosystem Studies in Millbrook, after examining nearly 20 years of data collected in Dutchess County, found that there was a higher risk of contracting Lyme in forests with larger numbers of rodents and fewer foxes, possums and raccoons. They also found that tick-borne diseases are closely associated with acorn supply.

The findings, published in the journal Ecology, found that sites with a high diversity of predators had lower infection rates from nymphal ticks, compared to sites dominated by coyotes, which sometimes drive out foxes and bobcats, which feed on rodents.
