Time series analysis of limber pine (Pinus flexilis) health in the U.S. Rocky Mountains in response to white pine blister rust (Cronartium ribicola) and bark beetles
From 2004-2007, 106 permanent limber pine monitoring plots were established and measured throughout the U.S. Rocky Mountains (MT, WY, CO) to characterize health trends in response to white pine blister rust (WPBR) and bark beetles (including mountain pine beetle, "MPB", and Ips spp., "Ips") over …

Population Structure and Biophysical Density Correlates of Whitebark Pine (Pinus albicaulis) at Two Treelines in the Northern Rocky Mountains
… rust, caused by the exotic fungal pathogen Cronartium ribicola. In this study, I aim to: 1) assess population structure and regeneration within two geographically different treelines experiencing contrasting levels of infection, and 2) examine associations among several biophysical variables …

Landscape pattern and blister rust infection in whitebark pine (Pinus albicaulis) at alpine treeline, Northern Rocky Mountains, U.S.A.
… by the fungus white pine blister rust (Cronartium ribicola). This disease affects all five-needled white pines, but has caused particularly widespread mortality in whitebark pine. Objectives of this research were: 1) to characterize the landscape structure of the treeline study sites at …

Modeling Blister Rust Incidence in Whitebark Pine at Northern Rocky Mountain Alpine Treelines: A Geospatial Approach
… by the invasive and exotic fungal pathogen (Cronartium ribicola) that causes white pine blister rust in five-needled pines. Originally thought to be limited to moderate environments, the disease is now found extensively throughout colder and dryer regions east of the Continental Divide, …

Mountain pine beetle outbreaks in high elevation whitebark pine forests: the effects of tree host species and blister rust infection severity on beetle productivity
… is also being killed by the exotic fungus, Cronartium ribicola, which causes the disease white pine blister rust (WPBR). This study examines MPB productivity in whitebark pine compared to that in lodgepole pine, and also in whitebark pine of varying WPBR infection severities to determine if …

Ecological Process and the Blister Rust Epidemic: Cone Production, Cone Predation, and Seed Dispersal in Whitebark Pine (Pinus albicaulis)
… of its range. The introduced fungal pathogen, Cronartium ribicola (white pine blister rust), infects whitebark pine and kills cone-bearing branches and trees. Blister rust has spread nearly rangewide and damage and mortality are highest in the northwest US and southwest Canada. Mortality caused …

The growth and productivity of ribes nigrum under various levels of shade and the implications for multifunctional woody polycultures
… alternate host to the white pine blister rust (Cronartium ribicola J.C Fisch In Rabh.), which caused extensive damage to the white pine (Pinus strobus) lumber industry. Upon legalization in the latter half of the 20th century, black currants have been making a slow comeback. The major interest …

Characterization of blackcurrant berries (Ribes nigrum) and the evaluation of their bioactive compounds after ultrasound-assisted water extractions, enzymatic treatments, and fermentation
… Ribes genus could act as vectors for the fungus Cronartium ribicola. Currently, some US farmers have a renewed interest in this high-value crop because BC and BC products are trending worldwide. BC are known to possess higher concentrations of anthocyanins (ANC) than other similarly colored …

Restoration planting options for Pinus flexilis James in the southern Rocky Mountains
Pinus flexilis James populations in the southern Rocky Mountains are severely threatened by the combined impacts of mountain pine beetles and white pine blister rust. P. flexilis' critical role in high elevation ecosystems heightens the importance of mitigating threats to P. flexilis survival. To …
