Microsite and elevation zone effects on seed pilferage, germination, and seedling survival during early whitebark pine recruitment
Tree recruitment is a spatially structured process that may undergo change over time because of variation in postdispersal processes. We examined seed pilferage, seed germination, and seedling survival in whitebark pine to determine whether 1) microsite type alters the initial spatial pattern of seed caches, 2) higher abiotic stress (i.e. higher elevations) exacerbates spatial distribution chan...
متن کاملMultivariate Analysis of Seedling Survival and Establishment and their Related Growth Attributes in Hammada elegans
Hammada elegans is a widely distributed shrub in arid rangelands. It has a potential for reseeding. Identification of reliable and easy to measure growth attributes will help in monitoring seedling survival and establishment in reseeding projects. The aim of this study is to identify seedling growth attribute(s) that can be used to predict survival and establishment of H. elegans using simple c...
متن کاملDiscussion Solution — N and CO2 effects on pine seedling growth
General approach These data are best analyzed by multiple regression, which can address all three hypotheses in one analysis. The first two hypotheses assert positive effects of the two independent variables separately, while the third hypotheses posits a positive (“reinforcement”) interaction between them; testing the latter therefore requires a multivariable analysis. The first two hypotheses...
متن کاملLongleaf Pine Seedling Production
Longleaf pine is a highly desirable species, resisting fire, insects and pathogens, and produces quality solid-wood products, but regeneration of the species has been difficult. Natural regeneration is feasible only on a small portion of the area considered to be longleaf pine type. Therefore, artificial regeneration must become a reliable means of regenerating the species if restoration of the...
متن کاملWater use by whitebark pine and subalpine fir: potential consequences of fire exclusion in the northern Rocky Mountains.
In subalpine forests of the northern Rocky Mountains, fire exclusion has contributed to large-scale shifts from early-successional whitebark pine (Pinus albicaulis Engelm.) to late-successional subalpine fir (Abies lasiocarpa (Hook.) Nutt.), a species assumed to be more shade tolerant than whitebark pine and with leaf to sapwood area ratios (A(L):A(S)) over twice as high. Potential consequences...
