Economic and Production Performance of Native Grasses as Forage in the Fescue Belt
-
The primary purpose of developing this literature review and summary was to inform producers about the potential benefits from utilizing warm-season grasses in the Fescue Belt. Effectively, managing forages is not always straightforward for livestock producers. Summarizing the economic and production benefits from using warm-season grasses could help producers make more informed forage management decision and might encourage producers to consider adopting warm-season grasses. Furthermore, this literature review also gathered information about the potential benefits of using native grasslands as forage to the quail population in this region, which could likely result in an economic benefit to the producer from leasing farmland to hunters.

Effects of Habitat Alterations on Bog Turtles (Glyptemys muhlenbergii): A Comparison of Two Populations
-
This study compared Bog Turtle population demography and habitat use from 1994 to 2009 at two sites in Massachusetts, USA: one site was managed for nonnative invasive species and natural succession (Site 1), and the other site was flooded from American Beaver (Castor canadensis) activity resulting in an expansion of nonnative invasive plants (Site 2).

Environmental DNA improves Eastern Hellbender (Cryptobranchus alleganiensis alleganiensis) detection over conventional sampling methods
-
Effective conservation planning relies on accurate species detection. However, conventional sampling methods used for detecting rare and cryptic aquatic species suffer from low probabilities of detection. Environmental DNA (eDNA) has emerged as an innovative and powerful sampling tool for detecting aquatic species, with previous studies suggesting a detection advantage over conventional sampling. However, comparative studies often fail to consider the appropriate sampling frameworks to adequately compare sampling methodologies and account for the influence of environmental variables on eDNA detection probabilities. In this study, we paired two detection methods (eDNA and physical sampling) at 22 sites in West Virginia, USA, to compare the probability of detecting a cryptic, elusive, and imperiled species of giant salamander, the Eastern Hellbender (Cryptobranchus alleganiensis alleganiensis). We used a multimethod occupancy modeling framework to compare method‐specific detection probabilities using a suite of predictor variables based on environmental conditions thought to influence hellbender detection. We detected hellbenders at 19/22 sites using eDNA and at 13/22 sites using physical sampling methods. The best supported model indicated that detection probability for eDNA (0.84 ± 0.06) was three times higher than conventional methods (0.28 ± 0.07). Water turbidity was the best predictor of hellbender detection and negatively impacted our ability to detect eDNA. We failed to detect an association between eDNA concentration and hellbender catch per unit effort. Our study supports previous findings that suggest eDNA sampling methods greatly increase the probability of detecting aquatic species. However, with little known about the influence of environmental variables on eDNA detection, our results highlight the negative influence turbidity and other physiochemical factors have on eDNA detection and suggest that further research on eDNA detection in turbid environments is needed.

Environmental Flows from Water Withdrawals in the Marcellus Shale Region
-
The Appalachian LCC collaborated with Cornell University to study the environmental impacts of water withdrawals in the Central Appalachian region. The rivers and streams of the Central Appalachians are home to more than 200 species of fish and other aquatic life. They also provide a reliable source of drinking water, recreational opportunities and associated economic benefits to people living in large cities and surrounding communities. This research looks at how the region’s surface freshwater supply – and the health of natural systems delivering this resource – have been impacted and may be altered in the coming years under increasing water withdrawals. It focuses on the Marcellus Shale region in the Central Appalachians, including portions of NY, PA, OH, MD, WV and VA.
