Managing the Extinction Risk of the Shenandoah Salamander

The Shenandoah salamander is an endangered salamander that is at risk of extinction due to its small, high-elevation range, competition with the co-occurring red-backed salamander, and the predicted future climate in the Appalachian mountain range. We are working with multiple partners to understand the current status of the species, predict future extinction risk, and engage stakeholders in a...

Quantifying Effects of Flow Variability on Riverine Biota

Stream and river biota around the world are imperiled by alterations to stream flow regimes that result from dams, land-use changes, water diversions and changing climate patterns. To manage and conserve stream-dependent species threatened by flow alterations, natural resource managers need quantitative information relating multiple aspects of ecological response to changes in a stream’s flow...

Modeling Sex-specific Demographic Rates in Metapopulations

The Challenge: Research that integrates population dynamics and ecological studies is needed to identify the causal factors involved in population declines and viability. For highly mobile organisms such as birds, “between-patch” movements and the use of different geographic sites and habitats at various stages of the annual cycle can make it difficult to measure the effectiveness of “within-...

Adaptive Management for Threatened and Endangered Species

The Challenge: Threatened and endangered species have to be managed in the face of uncertainty, but traditionally, there has been reluctance to think about adaptive management of listed species. Management agencies with responsibility for threatened and endangered species need tools to help manage in the face of uncertainty, with the hope of reducing that uncertainty.

Bacterial sulfur disproportionation constrains timing of neoproterozoic oxygenation

Black shales of the Late Devonian to Early Mississippian Bakken Formation are characterized by high concentrations of organic carbon and the hyper-enrichment (> 500 to 1000s of mg/kg) of V and Zn. Deposition of black shales resulted from shallow seafloor depths that promoted rapid development of euxinic conditions. Vanadium hyper-...

Cannel coal is a type of bituminous coal, which is the second-highest rank of coal (just behind anthracite). This particular sample has a high carbon content with high pollen and spore content as well. Unlike most bituminous coal, Cannel coal can be carved into ornaments. This sample came from the Eastern Interior Coalfield in Kentucky.
