Histology of White Pine Blister Rust in Needles of Resistant and Susceptible Eastern White Pine

Big Cypress fox squirrel (Sciurus niger avicennia) ecology and habitat use in a cypress dome swamp-pine forest mosaic

Forested wetlands are in decline, as are many species that are obligate residents. Big Cypress fox squirrels (BCFS; Sciurus niger avicennia) are a threatened endemic to wet pine and cypress forests in southwestern Florida. The region is characterized by development resulting in habitat loss, habitat fragmentation, and hydrological change that influence the quality of these wet forests. Through ...

Epicuticular Wax and White Pine Blister Rust Resistance in Resistant and Susceptible Selections of Eastern White Pine (Pinus strobus).

ABSTRACT Epicuticular wax on needles was evaluated for its influence on Cronartium ribicola infection of resistant and susceptible selections of Pinus strobus. Environmental scanning electron microscopy comparisons revealed that needles from a resistant selection of eastern white pine, P327, had a significantly higher percentage of stomata that were occluded with wax, fewer basidiospores germin...

The Mexican White Pine

The Arnold Arboretum has more than 40 species of pine growing on its grounds from throughout the geographic range of the genus. The Mexican White Pine, Pinus ayacahuite, is particularly intriguing because it is the Arboretum’s southernmost representative of the genus as well as being one of the very few Mexican plants hardy here. The 24-year-old specimen, propagated from seed from the Royal Bot...

Characterization of microsatellite markers in eastern white pine.

An enrichment cloning method was evaluated for the isolation of microsatellite loci from eastern white pine and the resulting markers were examined for polymorphisms. A 200-fold enrichment was achieved for highly abundant (AC)n repeats, but for much less abundant (ACAG)n repeats an enrichment of only 20-fold was obtained. Using a single set of PCR conditions, 19 microsatellite loci were identif...
