Adam R Ray, Russell W. Perry, Nicholas A. Som, Jerri L Bartholomew
2014, Transactions of the American Fisheries Society (143) 387-398
Parasites and pathogens influence the size and stability of wildlife populations, yet many population models ignore the population-level effects of pathogens. Standard survival analysis methods (e.g., accelerated failure time models) are used to assess how survival rates are influenced by disease. However, they assume that each individual is equally susceptible...

Remotely-sensed indicators of N-related biomass allocation in Schoenoplectus acutus
Jessica L. O’Connell, Kristin B. Byrd, Maggi Kelly
2014, PLoS ONE (9)
Coastal marshes depend on belowground biomass of roots and rhizomes to contribute to peat and soil organic carbon, accrete soil and alleviate flooding as sea level rises. For nutrient-limited plants, eutrophication has either reduced or stimulated belowground biomass depending on plant biomass allocation response to fertilization. Within a freshwater wetland...
