Post-Fire Growth of Seeded and Planted Big Sagebrush – Strategic Designs for Restoring Greater Sage-grouse Nesting Habitat

Recent wildfire-induced losses of big sagebrush are outpacing natural recovery and leading to substantial losses in habitat for species such as greater sage-grouse.

Year-Old Coho Capitalize on Stream Resources in Two Alaska Streams

The first year of life is perilous for a salmonid, typified by a critical period of post-emergence mortality.

Future Alpine Colonization by Limber Pine More Likely than by Engelmann Spruce

Alpine treelines are expected to shift upward in elevation and latitude as a result of climate change, yet this expansion requires favorable conditions for seed germination and successful seedling establishment.

Weed-Suppressive Bacteria Effects Differ in Culture Compared to in Soils

Weed-suppressive bacteria (WSB), specifically the D7 and ACK55 strains of Pseudomonas fluorescens, were previously reported to selectively inhibit growth of invasive annual grasses. However, recent studies show highly mixed evidence for WSB effectiveness in field settings.

Beyond Sticks and Stones: Integrating Both Abiotic and Biotic Factors into Watershed Restoration Assessments

Watershed assessments are often used to prioritize restoration, yet these assessments primarily focus on geomorphic conditions and less frequently incorporate abiotic factors, such as water chemistry and temperature, and biotic factors, such as the structure of food webs.

Spatial Grain of Adaptation is Much Finer than Ecoregional-Scale Common Gardens Reveal

Common-garden experiments, in which plants sourced from geographically distant populations are grown together such that genetic differences may be expressed, can provide insight on adaptive variation of sagebrush.

Bacterial Soil Amendment MB906 Shows Inconsistent Control of Invasive Annual Grasses

In 2016, land managers began using a soil amendment called MB906, a weed-suppressive bacteria, to control invasive annual grasses, yet the success of MB906 is inconclusive.

What to do when Invaders are out of Control?

Impacts from biological invasions are especially prevalent in freshwaters. Conventional approaches to managing invaders such as prevention, control, or eradication can be variably effective, difficult to implement, or socially undesirable.
