A study examining monarch butterflies' preferences for laying eggs on milkweed in cropland, open ground, or prairie—as well as predation rates on eggs in those settings—offers some mixed signals for monarch-conservation efforts.
A new study modeling potential future climate-change scenarios finds the potential for the invasive Japanese beetle to expand its range northward into new regions in North America, though some parts of it southern range could become too warm for it.
The invasive Asian longhorned tick could find plenty of suitable habitat in North America that is similar to its native region, according to new research from the Rutgers University Center for Vector Biology.
In the southern U.S., blacklegged tick larvae and nymphs can be found on hosts, but they don't otherwise show up in vegetation or—as a new study finds—in leaf litter or soil either. So where are they hiding?
The Aedes aegypti mosquito typically prefers humid climates, but it has gained a foothold in the arid southwestern U.S. by using manmade containers for breeding sites—in particular, flower pots and the saucers underneath them.
A new study in Connecticut finds that residential habitats harbor a greater diversity of animal hosts for blacklegged ticks, many of which don't transmit the Lyme disease pathogen Borrelia burgdorferi to ticks as well as white-footed mice do, thereby leading to lower levels of the pathogen's presence in residential areas compared to woodland habitats.
