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,...

Integrating continuous stocks and flows into state-and-transition simulation models of landscape change
Colin J. Daniel, Benjamin M. Sleeter, Leonardo Frid, Marie-Josée Fortin
2018, Methods in Ecology and Evolution (9) 1133-1143
State-and-transition simulation models (STSMs) provide a general framework for forecasting landscape dynamics, including projections of both vegetation and land-use/land-cover (LULC) change. The STSM method divides a landscape into spatially-referenced cells and then simulates the state of each cell forward in time, as a discrete-time stochastic process using a Monte Carlo...
To reduce the global burden of human schistosomiasis, use ‘old fashioned’ snail control
Susanne H. Sokolow, Chelsea L. Wood, Isabel J. Jones, Kevin D. Lafferty, Armand Kuris, Michael H. Hsieh, Giulio A. De Leo
2018, Trends in Parasitology (34) 23-40
Control strategies to reduce human schistosomiasis have evolved from ‘snail picking’ campaigns, a century ago, to modern wide-scale human treatment campaigns, or preventive chemotherapy. Unfortunately, despite the rise in preventive chemotherapy campaigns, just as many people suffer from schistosomiasis today as they did 50 years ago. Snail control can complement...
Making do with less: Must sparse data preclude informed harvest strategies for European waterbirds?
Fred A. Johnson, Mikko Alhainen, Anthony D. Fox, Jesper Madsen, Matthieu Guillemain
2018, Ecological Applications (28) 427-441
The demography of many European waterbirds is not well understood because most countries have conducted little monitoring and assessment, and coordination among countries on waterbird management has little precedent. Yet intergovernmental treaties now mandate the use of sustainable, adaptive harvest strategies, whose development is challenged by a paucity of demographic...
