If plants cannot simultaneously acclimate to shade and drought because of physiological trade-offs, then plants are expected to be less tolerant to shading under drier conditions. One observation that, at first sight, seems incompatible with this idea is the fact that the establishment of new plants in dry areas is often restricted to shady sites under the canopy of other plants, called “nurse plants.� We use a graphical model to resolve this paradox. The model visualizes how facilitative patterns can be understood from the simultaneous effects of plant canopies on microsite light and moisture, and the growth responses of establishing seedlings to those factors. The approach emphasizes the fact that positive...

Field data for vertical profiles of light and water quality parameters were collected biweekly between May and November in 2019 and June and October in 2020 in association with continuous monitoring platforms in Owasco, Seneca, and Skaneateles Lakes, Finger Lakes Region, New York. Water quality profiles were collected using Yellow Spring Instruments (YSI) EXO2 sondes and light profiles were collected using a LI-COR Photosynthetically Active Radiation (PAR) sensor in 2019 and Onset HOBO Pendant Temperature and Light data loggers in 2020. This data release includes all measured environmental parameters included in the analysis. This data release was produced in compliance with the open data requirements as a way...
Native plant recovery following wildfires is of great concern to managers because of the potential for increased water run-off and soil erosion associated with severely burned areas. Although postfire seeding with exotic grasses or cultivars of native grasses (seeded grasses) may mitigate the potential for increased run-off and erosion, such treatments may also be detrimental to long-term recovery of other native plant species. The degree to which seeded grasses dominate a site and reduce native plant diversity may be a function of the availability of resources such as nitrogen and light and differing abilities of native and seeded grasses to utilize available resources. We tested the hypothesis that seeded grasses...
