Huckleberry Gold is a purple-skin, yellow-flesh
fresh market cultivar with similar culinary qualities to the
market standard Yukon Gold. It has lower specific gravity,
sucrose and vitamin C content, but a significantly higher level
of tuber...

The potato psyllid, Bactericera cockerelli (Šulc), is
a vector of the bacterium ‘Candidatus Liberibacter
solanacearum’ (Lso) that has been linked to the economically
devastating zebra chip disease of potato. To date, four haplotypes
of the potato...

BACKGROUND: Half the world’s population lives in urban areas. It is therefore important to identify
characteristics of the built environment that are beneficial to human health. Urban greenness
has been associated with improvements in a diverse...

Fire-prone landscapes are not well studied as coupled human and natural systems (CHANS) and present many challenges
for understanding and promoting adaptive behaviors and institutions. Here, we explore how heterogeneity, feedbacks, and external...

The Sagebrush Steppe Treatment Evaluation Project (SageSTEP) is an integrated long-term study that evaluates ecological effects
of alternative treatments designed to reduce woody fuels and to stimulate the herbaceous understory of sagebrush...

Piñon (Pinus spp.) and juniper (Juniperus spp.) trees are reduced to restore native vegetation and avoid severe fires where they
have expanded into sagebrush (Artemisia tridentata Nutt.) communities. However, what phase of tree infilling should...

In response to the recent expansion of piñon and juniper woodlands into sagebrush-steppe communities in the northern Great Basin region, numerous conifer-removal projects have been implemented, primarily to release understory vegetation at sites...

The idea of college needs to shift from being about going to a “good school” for any
degree to "getting the right education” for what you want to do. I want to
investigate why we should be giving access to career assessment and preferred...

If arid sagebrush ecosystems lack resilience to disturbances or resistance to annual invasives, then alternative successional states
dominated by annual invasives, especially cheatgrass (Bromus tectorum L.), are likely after fuel treatments. We...

Managers reduce piñon (Pinus spp.) and juniper (Juniperus spp.) trees that are encroaching on sagebrush (Artemisia spp.)
communities to lower fuel loads and increase cover of desirable understory species. All plant species in these communities...

Current paradigm suggests that spatial and temporal competition for resources limit an exotic invader, cheatgrass (Bromus
tectorum L.), which once established, alters fire regimes and can result in annual grass dominance in sagebrush steppe....

A suite of eight rocks analyzed by the Curiosity Rover while it was stopped at the Rocknest sand
ripple shows the greatest chemical divergence of any potentially sedimentary rocks analyzed in the early
part of the mission. Relative to average...

In sagebrush ecosystems invasion of annual exotics and expansion of piñon (Pinus monophylla Torr. and Frem.) and juniper
(Juniperus occidentalis Hook., J. osteosperma [Torr.] Little) are altering fire regimes and resulting in large-scale...

BACKGROUND: We conducted a national level assessment of the quality of clinical care practice in the Ukrainian
healthcare system for two important causes of death and chronic disease conditions. We tested two hypotheses: a)
quality of care is...
