Method Based on Continuous Artificial Dry and Humid UV Treatments to Reduce the Luminescence Background in the Raman Spectra of Plastics

open access: yesJournal of Raman Spectroscopy, EarlyView.
We propose an UV photobleaching pretreatment to reduce the strong luminescence in the Raman spectra of plastic samples. Our protocol proves its efficiency whatever the luminescence origin (from the pigments or from a surface biofilm) but requires a careful optimization of the illumination conditions (UV wavelength, time, humidity) to reach the ...

Predicted genetic consequences of alternative population control strategies for North American plains bison in Yellowstone National Park

open access: yesThe Journal of Wildlife Management, EarlyView.
Management of bison in Yellowstone National Park under the available strategies that maintained ≥3,500 individuals (1:1 sex ratio), removed <40% of the population at a time and prioritized relatives for removal were predicted to maintain genetic variation at levels consistent with long‐term conservation (>95% of existing variation).
