Russet Burbank, Shepody, Frontier Russet, and Ranger Russet potatoes were tested for their response under furrow irrigation to PAM-treated irrigation water. The use of PAM was associated with an increase in US Number One tubers for Russet Burbank and Shepody varieties.
More than 200 sites between 500 and 2000 meters elevation
were examined utilizing a reconnaissance sampling technique for a
portion of the eastern slopes of the northern Oregon Cascade Mountains.
Twelve different forested plant communities were described
with data on vegetation, soils and topography. A map of their distribution
and...

Context:
Functional connectivity—the facilitation of individual movements among habitat patches—is essential for species’ persistence in fragmented landscapes. Evaluating functional connectivity is critical for predicting range shifts, developing conservation plans, and anticipating effects of disturbance, especially for species affected by climate change.
Objectives:
We examined whether simplifying forest structure influenced animal...

Diet quality influences ungulate population dynamics but is difficult to measure at fine temporal or spatial resolution using field-intensive methods such as fecal nitrogen (FN). Increasingly, the remotely sensed vegetation index NDVI is used to represent potential ungulate diet quality, but NDVI's relationship with diet quality has yet to be...

Climate change is arguably the greatest challenge to conservation of our time. Most
vulnerability assessments rely on past and current species distributions to predict
future persistence but ignore species’ abilities to disperse through landscapes, which
may be particularly important in fragmented habitats and crucial for long-term persistence
in changing environments....

Connectivity models using empirically-derived
landscape resistance maps can predict potential
linkages among fragmented animal and plant populations.
However, such models have rarely been used to
guide systematic decision-making, such as identifying
the most important habitat patches and dispersal corridors
to protect or restore in order to maximize regional
connectivity. Combining...
