Phytochemical Deterrence of Snowshoe Hare Browsing by Adventitious Shoots of Four Alaskan Trees
Abstract
After snowshoe hares have severely browsed deciduous trees and shrubs, these woody plants produce adventitious shoots that are extremely unpalatable to them. The adventitious shoots of four common boreal forest trees contain significantly higher concentrations of terpene and phenolic resins than the mature-growth-form twigs of the same species. These resins are experimentally shown to be repellent to snowshoe hares and appear to explain the avoidance of adventitious shoots by hares. The production of adventitious shoots after intense hare browsing and the avoidance of these shoots by hares may play an important role in the 10-year hare cycle.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
