Ips typographus and Dendroctonus ponderosae models project thermal suitability for intra- and inter-continental establishment in a changing climate

Publications Posted on: July 08, 2019
Climate change is altering legacies of native insect-caused disturbances and contributing to non-native invasions globally. Many insect fitness traits are temperature dependent and projected climatic changes are expected to cause continued alterations in insect-caused tree mortality, with uncertain consequences for forest ecosystems and their management.

Northeastern California plateaus bioregion science synthesis

Projects Posted on: April 20, 2018
The Lassen and Modoc National Forests are revising their Forest Plans, guided by the 2012 Planning Rule. This requires public and tribal input throughout the process and embraces the fact that ecological, social, and economic objectives are interrelated. Because ecological, social, and economic conditions have changed since the original forest plans were written and new science is available, preparing a science synthesis, guided by input from the public, tribes, and forest staffs, is the first step in a multi-step process that eventually leads to revised forest plans.

GSD Update: Year in Review: Spotlight on 2017 Research by the Grassland, Shrubland and Desert Ecosystems Science Program

Publications Posted on: April 10, 2018
In this issue of the GSD Update, we feature selected studies of the RMRS Grassland, Shrubland and Desert Ecosystems Science Program (GSD) that focus on the theme of fire. Significant results of recent research and science delivery by GSD scientists are highlighted. We feature program research that lines up with the strategic priorities and goals of the USDA Forest Service (USFS).

Global trade and the spread of invasive species

Science Spotlights Posted on: March 01, 2018
Scientists, engineers, and economists have joined together to learn more about the link between trade and species spread around the globe. This project is called "The Non-indigenous Species World Risk Assessment and Prediction System." 

Phylogenetic and population analyses of the invasive brown root-rot pathogen (Phellinus noxius) highlight the existence of at least two distinct populations

Publications Posted on: December 12, 2017
Phellinus noxius (Corner) G. H. Cunn is a vastly destructive, fast-growing pathogen that affects a wide range of woody hosts in pan-tropical areas, including Asia, Australia, Africa, and Oceania (Ann et al. 2002). This invasive pathogen causes brown root-rot disease on cacao, coffee, and rubber, as well as diverse fruit, nut, ornamental, and other native/exotic trees, and little host specificity is known to occur (Sahashi et al. 2010).

Development of single-nucleotide polymorphism markers for Bromus tectorum (Poaceae) from a partially sequenced transcriptome

Publications Posted on: January 12, 2017
Premise of the study: Bromus tectorum (Poaceae) is an annual grass species that is invasive in many areas of the world but most especially in the U.S. Intermountain West. Single-nucleotide polymorphism (SNP) markers were developed for use in investigating the geospatial and ecological diversity of B. tectorum in the Intermountain West to better understand the mechanisms behind its successful invasion.

Innovative control and management of white pine blister rust – the proactive strategy for mountaintop ecosystems

Projects Posted on: December 03, 2014
RMRS and partners have developed a strategy to sustain healthy high elevation pine populations and mitigate the impact of invasion by the non-native pathogen that causes the lethal disease white pine blister rust. This approach provides the science foundation for proactive management.   

First report of Puccinia psidii caused rust disease epiphytotic on the invasive shrub Rhodomyrtus tomentosa in Florida

Publications Posted on: October 24, 2013
Rhodomyrtus tomentosa (Aiton) Hassk. (downy-rose myrtle, family: Myrtaceae), of South Asian origin, is an invasive shrub that has formed monotypic stands in Florida (3). During the winter and spring of 2010 through 2012, a rust disease of epiphytotic proportion was observed on young foliage, stem terminals, and immature fruits of this shrub in natural areas of Martin and Lee counties, Florida.

Roads impact the distribution of noxious weeds more than restoration treatments in a lodgepole pine forest in Montana, U.S.A

Publications Posted on: June 03, 2011
A century of fire suppression has created unnaturally dense stands in many western North American forests, and silviculture treatments are being increasingly used to reduce fuels to mitigate wildfire hazards and manage insect infestations.

Biology and pathology of Ribes and their implications for management of white pine blister rust

Publications Posted on: December 02, 2010
Ribes (currants and gooseberries) are telial hosts for the introduced and invasive white pine blister rust fungus, Cronartium ribicola. Knowledge of wild and introduced Ribes helps us understand the epidemiology of blister rust on its aecial hosts, white pines, and develop disease control and management strategies. Ribes differ by species in their contribution to initial establishment and subsequent intensification of blister rust.
