Assessing Hybridization Risk Between ESA-Listed Native Bull Trout (Salvelinus confluentus) and Introduced Brook Trout (S. fontinalis) Using Habitat Modeling

open access: yesFrontiers in Environmental Science, 2022
The introduction of non-native species can negatively impact native species through reduced genetic fitness resulting from hybridization. The lack of spatiotemporal data on hybrid occurrences makes hybridization risk assessment difficult.

Steam gasification of bagasse: Effect of heating rate [PDF]

open access: yes, 2019
Bagasse residue is a potential feedstock for steam gasification, but knowledge of this technology is still small and fragmented. Heating rate is of the most important factors influencing the gasification process.
