Environmental Risk Assessment

Environmental impact assessment of double- and relay-cropping with winter camelina in the northern Great Plains, USA – M Berti, B Johnson, D Ripplinger, R Gesch, A Aponte – Agricultural Systems 2017

Summary: Recent findings indicate that double- or relay-cropping winter camelina with forage or food crops can increase yield per area, improve energy balance, and provide several ecosystem services. Double-cropping can help balance food and energy production. The objective of this study was to determine the environmental impact of double- and relay-cropping systems as compared with monocultured maize and soybean in ...

The invasion potential and competitive ability of Camelina sativa (L.) Crantz (camelina) in rangeland ecosystems – Davis, P.B. – University of Montana, Thesis, 2010

Summary: Objectives of this study were to 1) quantitatively assess the invasion potential of C. sativa by collecting demographic data over two years and developing a population dynamics model, 2) compare experimental results and modeling outcomes to predictions suggested by a qualitative weed risk assessment system, and 3) assess the impact of growing conditions on the relative competitiveness of C. ...

Preliminary ecotoxicity assessment of new generation alternative fuels in seawater – G. Rosen, R.E. Dolecal, M.A. Colvin, and R.D. George – Chemosphere 2014

Summary: Standard laboratory-based toxicity experiments were conducted for two alternative fuels, jet fuel derived from Camelina sativa  seeds (HRJ5) and diesel fuel derived from algae (HRD76), and two conventional counterparts, jet fuel (JP5) and ship diesel (F76). Initial toxicity tests performed on water-accommodated fractions (WAF) from neat fuels partitioned into seawater, using four standard marine species in acute and chronic/sublethal ...

Transient Seed Bank of Camelina Contributes to a Low Weedy Propensity in Western Canadian Cropping Systems – K.D. Walsh, L.L. Raatz, K.C. Topinka, and Linda M. Hall – Crop Science 2013

Summary: While camelina has high fecundity and large seed losses at harvest, it has limited seed bank persistence and is unlikely to become a weed of agricultural areas. Link: https://www.crops.org/publications/cs/abstracts/53/5/2176

First report of outcrossing rates in camelina [Camelina sativa (L.) Crantz], a potential platform for bioindustrial oils – K.D. Walsh, D.M. Puttick, M.J. Hills, R-C Yang, K.C. Topinka, and L.M. Hall – Canadian Journal of Plant Science 2012

Summary: Outcrossing rates in camelina were low (0.09-0.28%), suggesting camelina is a primarily self-pollinated species. Outcrossing was affected by flowering synchrony influenced by planting date as well as direction and distance (20, 40 or 60 cm) from the pollen source. Pollen-mediated intra-specific gene flow is unlikely to prohibit the development of camelina as a bio-industrial platform. Short distance outcrossing results ...

Hybridization between Camelina sativa (L.) Crantz (false flax) and North American Camelina species – G. Séguin-Swartz, J.A Nettleton, C. Sauder, S.I. Warwick, and R.K. Gugel – Plant Breeding 2013

Summary: The potential for gene flow between Camelina and its wild North American relatives C. alyssum, C. microcarpa and C. rumelica subsp. rumelica, was investigated. The study provided evidence that should the species have sympatric distributions and overlapping flowering periods, gene flow between C. sativa and its wild North American relatives is possible and that it would most likely occur ...
