Persistence of genetically engineered canola populations in the U.S. and the adventitious presence of transgenes in the environment.

Autor: Steven E Travers, D Bryan Bishop, Cynthia L Sagers

Publikováno v: PLoS ONE, Vol 19, Iss 5, p e0295489 (2024)

Feralization of genetically engineered (GE) crops increases the risk that transgenes will become integrated into natural and naturalizing plant populations. A key assumption of the management of GE crops is that populations of escaped plants are shor

Genomic and resistance gene homolog diversity of the dominant tallgrass prairie species across the U.S. Great Plains precipitation gradient.

Autor: Matthew N Rouse, Amgad A Saleh, Amadou Seck, Kathleen H Keeler, Steven E Travers, Scot H Hulbert, Karen A Garrett

Publikováno v: PLoS ONE, Vol 6, Iss 4, p e17641 (2011)

Environmental variables such as moisture availability are often important in determining species prevalence and intraspecific diversity. The population genetic structure of dominant plant species in response to a cline of these variables has rarely b

The establishment of genetically engineered canola populations in the U.S.

Autor: Meredith G Schafer, Andrew A Ross, Jason P Londo, Connie A Burdick, E Henry Lee, Steven E Travers, Peter K Van de Water, Cynthia L Sagers

Publikováno v: PLoS ONE, Vol 6, Iss 10, p e25736 (2011)

Concerns regarding the commercial release of genetically engineered (GE) crops include naturalization, introgression to sexually compatible relatives and the transfer of beneficial traits to native and weedy species through hybridization. To date the

The timing of snowmelt and amount of winter precipitation have limited influence on flowering phenology in a tallgrass prairie

Autor: Steven E Travers Travers, Miss Emma K Chandler

Publikováno v: Botany. 100:301-311

A growing body of work indicates that the timing of flowering of temperate angiosperms has been affected by shifts in climate since the 1970s. Sensitivity in flowering phenology to changing temperatures has been particularly well-documented, but wide

Evidence of local adaptation in temperature tolerance traits of the gametophytic and sporophytic stages in Solanum carolinense (horsenettle)

Autor: Emma K. Chandler, Steven E. Travers

Climate change is rapidly altering local temperature regimes and in different ways across the landscape. To cope with these rapid changes, plant species must have the capacity to respond to changes in temperature stress or risk extinction. We compare

Flowering cues in a Costa Rican cloud forest: analyzing the effect of climate

Autor: Steven E. Travers, Ned A. Dochtermann

The influence of a changing climate on the phenology of organisms in a region is dependent on how regional climate cues or modifies the timing of local life history events and how those cues are changing over time. There is extensive evidence of phen

Forty Years of Increasing Precipitation is Correlated with Loss of Forbs in a Tallgrass Prairie

Autor: Lauren A. Dennhardt, Laura Aldrich-Wolfe, Steven E. Travers, W. Gaya Shivega, Katie L. Black

Publikováno v: Natural Areas Journal. 41

The effects of climate change on plant communities are already observable in many regions. In the tallgrass region of the Northern Great Plains, plant community composition may have shifted in response to increases in both annual precipitation and te

Breeding system and inbreeding depression in the rare orchid, Platanthera praeclara, in a fragmented grassland landscape

Autor: Pati Vitt, Steven E. Travers, Kirk M. Anderson, Marion O. Harris

Publikováno v: Botany. 96:151-159

An important consequence of self-compatibility in plants is that self-pollination can have deleterious effects on plant fitness because of inbreeding. We conducted a hand pollination experiment under field conditions to measure the magnitude of inbre

Microsatellite Markers in the Western Prairie Fringed Orchid, Platanthera praeclara (Orchidaceae)

Autor: Andrew A. Ross, Laura Aldrich-Wolfe, Stacey Lance, Travis Glenn, Steven E. Travers

Publikováno v: Applications in Plant Sciences, Vol 1, Iss 4, p 1200413 (2013)

Premise of the study: Primers for 31 microsatellite-containing loci were developed for the threatened orchid Platanthera praeclara to enable characterization of the population genetics of this tallgrass prairie native. Methods and Results: Sixteen
