Bioenergy and biological invasions: ecological, agronomic and policy perspectives on minimizing risk.

Book cover for Bioenergy and biological invasions: ecological, agronomic and policy perspectives on minimizing risk.


This book contains 9 chapters focusing on the ecological, agronomic and policy perspectives on minimizing risk of bioenergy and biological invasions. Topics covered include potential risks of algae bioenergy feedstocks, gene flow and invasiveness in bioenergy systems, use of weed risk assessments to separate the crops from the weeds and eradication and control of bioenergy feedstocks, among others...

"Seeded-yet-sterile" perennial grasses: towards sustainable and non-invasive biofuel feedstocks.

Sustainable cropping systems for leading candidate biofuel crops currently focus predominantly on perennial grasses for which assessments of invasiveness potential remain incomplete. Perennial C4 grasses have significant capacity for biomass accumulation across diverse environments, providing intrinsic value towards protection and restoration of underutilized, marginal, and degraded lands. Varied seed and vegetative reproduction mechanisms, however, contribute to their invasive potential. The development of feedstocks possessing the minimum vegetative propagules required for perennial life habit, combined with seed sterility, would therefore greatly reduce the risk of perennial biofuel crops becoming biological invaders. Pearl millet-napiergrass ("PMN"; Pennisetum glaucum [L.] R. Br. × Pennisetum purpureum Schumach.) and king-grass (P. purpureum × P. glaucum) are examples of such feedstocks, being "seeded-yet-sterile" crops in which fertile parents allow seeded production of hybrids that are subsequently both seed-sterile and devoid of rhizomes in biomass production fields. The use of genomics tools provide further tools suitable for both characterizing genetic mechanisms governing weediness and deploying marker-assisted breeding programs for biofuel crops with reduced risk of negative environmental impacts.
