We expected that swamp sparrows could be modeled using a non-linear (positive unimodal) relationship with
Lythrum salicaria. Whitt et al.
One individual of
Lythrum salicaria was found on our initial site visit and can also be controlled if immediate removal steps are taken.
The plants used in this study included the purple loosestrife (
Lythrum salicaria), the common cattail (Tyhpa sp.), and a common wetland grass (Panicum sp.).
A study of multivariate selection on correlated characters in
Lythrum salicaria indicated that there is a combination of stabilizing and directional selection on the timing of initial flowering, and strong directional selection favoring a long flowering duration (O'Neil 1997).
And the purple loosestrife (
Lythrum salicaria) - which which has edged out cattails and other prime waterfowl habitat along much of the Great Lakes shoreline - may have arrived in the early 1800s with sheep from Europe or as a cultivated plant.
