University of Wyoming Extension is offering leadership classes on the Wind River Reservation beginning in September.

The three-session “Be the Change Leadership School” meets once a month.

Attendance at all three sessions is encouraged, said Tina Russell, a community development educator who is offering the course with fellow educators Hannah Swanbom and Tara Kuipers. Participants who are employed should have the support of their employer to assure participation in all class days, she said.

Sessions are 10 a.m. to 4 p.m. at various locations on the reservation. Swanbom said a detailed schedule with locations will be sent by email prior to each class. Lunch and additional materials are provided each session.

Dates, leadership topic and community focus are:

Friday, Sept. 12 – Personality and leadership skills; water and natural resources

Friday, Oct. 17 – Responsibilities of leadership; economic and business development

Friday, Nov. 14 – Community leadership; adult and higher education

Registration is requested by Monday, Sept. 1. For more information, contact Russell at 307-332-2135 or jtoth1@uwyo.edu; Kuipers at 307-527-8560 or tkuipers@parkcounty.us; or Swanbom at 307-235-9400 or hswanbom@natronacounty-wy.gov.

UW scientists study how complexity developed from simple cell

Consider this a matter of scrambling down the family tree to its roots.

Really old roots.

Or perhaps it’s more like blowing the dust off the family album – the human album – and opening to the first pages billions of years ago.

Naomi Ward, an associate professor in the Department of Molecular Biology at the University of Wyoming, is the senior author on a paper recently published in Proceedings of the National Academy of Sciences USA (PNAS).

The research examines how simple bacterial cells could have made the transition to more complex cells, leading to plants, animals and humans.

The paper, “Spatially segregated transcription and translation in cells of the endomembrane-containing bacterium Gemmata obscuriglobus,” was published online this week, and describes research supported by a grant from the National Science Foundation (NSF).

Ekaterina Gottshall, a graduate student in the Molecular and Cellular Life Sciences Ph.D. program, is first author on the paper and main contributor to the experimental work. Other authors are assistant professor Jay Gatlin, also in molecular biology, and Corrine Seebart, an assistant research scientist in Ward’s group.

Ward’s version of genealogy looks at how simple bacterial cells, which do not have the nuclear membrane that separates transcription and translation (the reading of DNA instructions to make protein), could have evolved into eukaryotic cells (plants, animals, humans), which have transcription and translation occurring in separate locations.

Stripe rust, wheat stem sawfly pestering southeast Wyoming wheat fields

University of Wyoming scientists found stripe rust and wheat stem sawfly affecting wheat fields in southeastern Wyoming during their survey of 61 field sites.

UW Extension plant pathologist Bill Stump and research assistant Wendy Cecil, both in the Department of Plant Sciences in the College of Agriculture and Natural Resources, toured fields June 9-13 and June 16-17.

Overall wheat yields are expected to be above average, according to their report, but they found several dryland fields noticeablyinfected by stripe rust in southeastern Goshen, eastern Laramie and Platte counties. Warm and dry weather could curtail the extent of the disease, they noted.

UW Extension bulletin explains using native plants, adapted seed sources for reclamation

seed coverA new bulletin from the University of Wyoming Extension addresses using native plants and adapted seed sources to help reclaim severely disturbed lands.

Native plants represent key resources for restoration of ecosystem functions and wildland health, state authors assistant professor and extension restoration ecologist Kristina Hufford and Rachel Mealor, extension range specialist, both in the Department of Ecosystem Science and Management.

“Successful Restoration of Severely Disturbed Lands: Native Plants and Adapted Seeds for Reclamation,” B-1256, includes resources for the selection of native plant species and appropriate seed sources for revegetation of degraded lands in the state and region.

“This bulletin addresses questions we’ve received during workshops about the selection of native plant species and the use of different seed sources in land reclamation and restoration,” said Hufford, who also participates in the School of Energy Resources.

The bulletin is available for free download by going to http://www.uwyo.edu/ces and clicking Publications in the left-hand column, then typing B-1256 in the search field.

For more information, contact Hufford at 307-766-5587 or at khufford@uwyo.edu.

A plant scientist with years of experience teaching students and conducting studies at research and extension centers is the new head of the Department of Plant Sciences at the University of Wyoming.

Jim Heitholt will leave his crop physiology position with Texas A&M University – Commerce and join the College of Agriculture and Natural Resources Aug. 18. He is scheduled to attend the Powell Research and Extension Center field day Thursday, July 17, near Powell.

“The appointment is a very exciting time for me personally,” said Heitholt, a professor in the Department of Agricultural Sciences with Texas A&M University – Commerce, who also has a joint appointment in the Department of Soil and Crop Sciences at College Station.

 “I am extremely grateful for this opportunity and intend to serve the students, faculty, staff, and college leadership and stakeholders as wisely and enthusiastically as I possibly can,” he said.

Bret Hess, associate dean of research in the college, served as one of two interim department heads during the search to fill theposition.
