Stratigraphy, paleoflora, and tectonic setting of the Paleogene Sheep Creek volcanic field, central Alaska
In this paper, we provide new information on the stratigraphy and paleoflora of the Sheep Creek volcanic field in the Alaska Range that bolsters our understanding of a key interval in the tectonic, paleoclimate, and paleoenvironmental history of the northern Cordillera. Although the distribution and basic stratigraphy of these rocks have been previously reported, here we document the stratigraphic
Environmental DNA
The widespread adoption of environmental DNA (eDNA) detection tools for biodiversity monitoring has led to the need for universal data standards to inform principled eDNA data applications. Improvements in understanding the meaning and possible uncertainty of eDNA data can minimize erroneous conclusions, increase confidence in eDNA data, and maximize conservation outcomes.

Milkweed and floral resource availability for monarch butterflies (Danaus plexippus) in the United States
The global decline of pollinators, particularly insects, underscores the importance of enhanced monitoring of their populations and habitats. However, monitoring some pollinator habitat is challenging due to widespread species distributions and shifts in habitat requirements through seasons and life stages. The monarch butterfly (Danaus plexippus), a migratory insect pollinator that breeds widely

Post-Fire Sediment Research at the Pacific Coastal and Marine Science Center
The USGS Pacific Coastal and Marine Science Center (PCMSC) in Santa Cruz, California, has been growing our post-fire research contributions since 2017, through studies of post-fire sediment movement that address the Natural Hazards Mission Area objectives for understanding wildfire hazards.
Improving Postfire Debris-Flow Hazard Assessments In The Pacific Northwest Through Application Of Debris-Flow Models
As part of the Post-fire Hazards and Impacts to Resources and Ecosystems (PHIRE): Support for Response, Recovery, and Mitigation Project, the PHIRE Debris Flow Hazard team is engaging in several studies to better understand the spatial and temporal drivers of postfire debris flows and improve postfire hazard assessments across northern California and the Pacific Northwest.
Can ruderal components of biocrust (mosses and cyanobacteria) be maintained under increasing threats of drought, grazing and feral horses?
Biological soil crusts (biocrusts) are a community of living organisms, like moss, lichen, and algae, covering soils in arid and semi-arid ecosystems, providing important ecological functions like carbon cycling and soil stabilization. Analyses show that biocrusts are negatively associated with the abundance of invasive annual grasses that are responsible for increasing fire across the Great Basin...
