Jane E. Austin, Wesley E. Newton
2019, Scientific Investigations Report 2018-5168
The health and function of northern peatlands, particularly for fens, are strongly affected by fire and hydrology. Fens are important to several avian species of conservation interest, notably the yellow rail (Coturnicops noveboracensis). Fire suppression and altered hydrology often result in woody encroachment, altering the plant community and structure. Woody...
Clastic pipes and mud volcanism across Mars: Terrestrial analog evidence of past Martian groundwater and subsurface fluid mobilization
D. F. Wheatley, M. A. Chan, Chris Okubo
2019, Icarus (328) 141-151
Clastic pipes are cylindrical injection features that vertically crosscut bedding with sharp contacts. Terrestrial pipes have cylindrical morphologies, massive or radially graded interiors, and raised outer rims. Increased grain size and subsequent cementation along the more porous edges makes the rims more resistant to weathering. Pipes have crosscutting relationships with...

Larry M. Gigliotti, Lily A. Sweikert
2019, Proceedings of the South Dakota Academy of Science
It is well known that farmers are getting older; in the United States the average age of farmers is 58.3 years old and the rate of increase in age is accelerating. The average farmer age increased 10 years from 47.6 years old to 57.1 in a four year period (2003-2007)....
Opportunities and barriers for endangered species conservation using payments for ecosystem services
Aaron M. Lien, Colleen Ulibarri, Wendy Vanasco, George B. Ruyle, Scott A. Bonar, Laura Lopez-Hoffman
2019, Biological Conservation (232) 74-82
Endangered species laws seek to prevent extinction by outlawing actions that may cause harm or lead to extinction. In doing so, these laws are sometimes criticized for limiting management flexibility and subjecting landowners to regulatory burdens. One proposed solution to this challenge is development of payment for ecosystem service (PES) programs....
