Eric J. Sargis, Virginie Millien, Neal Woodman, Link E. Olson
2018, Ecology and Evolution (8) 1634-1645
There are a number of ecogeographical “rules” that describe patterns of geographical variation among organisms. The island rule predicts that populations of larger mammals on islands evolve smaller mean body size than their mainland counterparts, whereas smaller‐bodied mammals evolve larger size. Bergmann's rule predicts that populations of a species in...
Behavior and reproductive ecology of the Sicklefin Redhorse: An imperiled southern Appalachian Mountain fish
Scott D. Favrot, Thomas J. Kwak
2018, Transactions of the American Fisheries Society (147) 204-222
Many nongame fishes are poorly understood but are essential to maintaining healthy aquatic ecosystems globally. The undescribed Sicklefin Redhorse Moxostoma sp. is a rare, imperiled, nongame fish endemic to two southern Appalachian Mountain river basins. Little is known of its behavior and ecology, but this information is urgently needed for conservation planning....

David Dukes, Howell B. Gonzales, Sujith Ravi, David E. Grandstaff, R. Scott Van Pelt, Junran Li, Guan Wang, Joel B. Sankey
2018, Journal of Geophysical Research: Biogeosciences (123) 288-299
Grasslands, which provide fundamental ecosystem services in many arid and semiarid regions of the world, are undergoing rapid increases in fire activity and are highly susceptible to postfire-accelerated soil erosion by wind. A quantitative assessment of physical processes that integrates fire-wind erosion feedbacks is therefore needed relative to vegetation change,...

2018, Remote Sensing of Environment (204) 534-552
This paper explores for the first time the possibilities to use two land surface temperature (LST) time series of different origins (geostationary Meteosat Second Generation satellite data and Noah land surface modelling, LSM), to detect geothermal anomalies and extract the geothermal component of LST, the LSTgt. We hypothesize that...
The nitrogen window for arctic herbivores: plant phenology and protein gain of migratory caribou (Rangifer tarandus)
Perry S. Barboza, Lindsay L. Van Someren, David D. Gustine, M. Syndonia Bret-Harte
2018, Ecosphere (9)
Terrestrial plants are often limited by nitrogen (N) in arctic systems, but constraints of N supply on herbivores are typically considered secondary to those of energy. We tested the hypothesis that forage N is more limiting than energy for arctic caribou by collecting key forages (three species of graminoids, three...

Exudation rates and δ13C signatures of tree root soluble organic carbon in a riparian forest
S. W. Gougherty, J. E. Bauer, J. W. Pohlman
2018, Biogeochemistry (137) 237-252
Tree root exudation (TRE) of water soluble organic carbon (WSOC) is an important but under-assessed component of net primary production, and is thought to strongly influence rhizosphere biogeochemistry. Riparian systems in particular are often viewed as biogeochemical hot spots fueled partially by root exudate WSOC. However, TRE rates have not...

Equilibrium and non-equilibrium controls on the abundances of clumped isotopologues of methane during thermogenic formation in laboratory experiments: Implications for the chemistry of pyrolysis and the origins of natural gases
Yanhua Shuai, Peter M.J. Douglas, Shuichang Zhang, Daniel A. Stolper, Geoffrey S. Ellis, Michael Lawson, Michael Lewan, Michael Formolo, Jingkui Mi, Kun He, Guoyi Hu, John M. Eiler
2018, Geochimica et Cosmochimica Acta (223) 159-174
Multiply isotopically substituted molecules (‘clumped’ isotopologues) can be used as geothermometers because their proportions at isotopic equilibrium relative to a random distribution of isotopes amongst all isotopologues are functions of temperature. This has allowed measurements of clumped-isotope abundances to be used to constrain formation temperatures of several natural materials. However,...
