متن کاملChain reactions linking acorns to gypsy moth outbreaks and Lyme disease risk.
In eastern U.S. oak forests, defoliation by gypsy moths and the risk of Lyme disease are determined by interactions among acorns, white-footed mice, moths, deer, and ticks. Experimental removal of mice, which eat moth pupae, demonstrated that moth outbreaks are caused by reductions in mouse density that occur when there are no acorns. Experimental acorn addition increased mouse density. Acorn a...
متن کاملDynamics of a plant-herbivore model with applications to gypsy moth outbreaks
We formulate a novel host parasite model to study the dynamics of the outbreak of the gypsy moths. Assuming a Ricker dynamics for the host population and an infestation that takes place after the growth limitations take effect in the plant dynamics, a two dimensional discrete model of the leaf mass and the gypsy moths mass is constructed. The parameter space is determined by the growth rate of ...
متن کاملEffects of Invasive Winter Moth Defoliation on Tree Radial Growth in Eastern Massachusetts, USA
Winter moth, Operophtera brumata L. (Lepidoptera: Geometridae), has been defoliating hardwood trees in eastern Massachusetts since the 1990s. Native to Europe, winter moth has also been detected in Rhode Island, Connecticut, eastern Long Island (NY), New Hampshire, and Maine. Individual tree impacts of winter moth defoliation in New England are currently unknown. Using dendroecological techniqu...
متن کاملOak mast seeding as a direct cause of gypsy moth outbreaks?
In our paper (Liebhold et al. 2000) we reviewed the literature on the dynamics of the gypsy moth (Lymantria dispar L.) populations in North America. This paper highlighted a previously developed hypothesis, namely that gypsy moth outbreaks are caused by decreased rates of predation by small mammal predators as a result of diminished predator populations following years of low mast production by...
