Dryopteris intermedia (Common Wood Fern) is more associated with coarse woody debris (CWD) than the surrounding forest floor. Along with microsite-based establishment benefits, dispersal vectors may facilitate this distribution. Some salamanders are associated with CWD and may serve as dispersal agents for spores of the Common Wood Fern. In a deciduous forest of south-central New York State, we assessed the ability of Plethodon cinereus (Red-backed Salamander) and Notophthalmus viridescens (Eastern Newt) to pick up and transport spores and sori fragments from the dorsal side of the frond, and rinsed salamanders to collect and germinate any viable spores from their bodies. We also measured the moisture content of soft CWD, soil beneath hard CWD, and background soil. Both salamander species picked up reproductive components of Common Wood Fern. Wild-caught salamanders of both species had viable spores on their bodies. Soft CWD held more moisture than soil beneath hard CWD and the forest-floor soil. Dispersal by salamanders and the provision of humid habitat by soft CWD may help to explain the abundance of Common Wood Fern near CWD.

Fallopia japonica (Houtt.) Ronse Decraene is an invasive plant species that introduces economic, social, and environmental stresses. After observing frost damage to F.japonica plants in the field, we exposed leaves of F.japonica and a native species (Acer saccharum Marshall) to freezing temperatures in the laboratory and compared their net photosynthetic rate to that of fresh leaves. In both species, the net photosynthetic rate of leaves frozen for 0.5h or for 1h were not significantly different from each other but were both significantly less than that of fresh leaves. Fresh leaves of F.japonica had a higher net photosynthetic rate than those of A.saccharum, but the relationship was reversed in all freezing treatments. Frozen leaves of F.japonica contained microscopically visible frost lenses, which revealed the mechanism of the damage. These results quantify how quickly F.japonica is damaged by freezing conditions and suggest that minimum vernal temperatures may limit its range expansion. © 2015 The Society for the Study of Species Biology.

Forested parks are an urban oasis, and forest management plays an important part in their maintenance. I used a systematic sampling technique to quantify the vegetation and propagule bank in a small urban park prior to and following a forest management event. The number of non-forest species and the abundance of Toxicodendron radicans (Poison Ivy) increased after forest harvest. Distance from an edge did not affect the change in vegetation. In the propagule bank, loss of basal area in a plot was positively correlated with an increase in the percent of species that were non-forest and non-native. The Sørenson coefficient of community similarity comparing the species composition of the vegetation before and after harvest was 0.769 (out of 1.0), but that for the propagule bank was 0.308. Forest management practices in small urban parks should be designed with extreme caution due to the volatile settings of these refuges.
