Endless Symbioses Most Intricate, W. John Hayden

Biology Faculty Publications

Orchids, such as our Wildflower of the Year for 2016, Downy Rattlesnake Plantain (Goodyera pubescens) (Fig. 1), exemplify the interconnectedness of life on Earth. As would be the case for many kinds of plants, pollination comes readily to mind as a prominent example of mutualistic symbiosis. Downy Rattlesnake Plantain is pollinated by bumblebees and other native bees. The bees gain nectar and the orchid gets an efficient means to move pollen from one flower to another; each organism gains benefit from the interaction, the very definition of mutualism. Pollination by bees is widespread among the orchids, but there …

Per Axel Rydberg’S Botanical Collecting Trips To Western Nebraska In 1890 And 1891, Robert B. Kaul, David M. Sutherland

Zea E-Books Collection

In the summer of 1891, Per Axel Rydberg and his assistant, Julius Hjalmar Flodman, collected plants in western Nebraska for the United States Department of Agriculture. They collected many first-records for Nebraska as well as some that became type specimens of Rydberg’s and other botanists’ names. In the following autumn and winter, Rydberg made a detailed, typewritten, carbon copied 35-page Report and 37-page List of specimens from that trip; one carbon copy is in the Bessey Herbarium (NEB) at the University of Nebraska–Lincoln. It is these documents that we present here, extensively annotated with our geographic clarifications, original and updated …

Mapping Morels: Predicting The Locations Of Morchella Species Through Environmental Factors Using The Gis System, Emily M. Stanevicius

Celebration of Learning

Morel mushrooms, Morechella esculenta and M. deliciosa, are known delicacies across the globe, ranging from exquisite dishes in French cuisine to Eastern palates such as Japanese Matsutake. According to literature, true morels diverged as their own genus about 129 million years, again which has led to the development of more than 177 species and have been part of the human diet since their beginning. However, the elusiveness of morels has contributed to the mushrooms infamy for rarity, and has even been known to sell for more than $40 per pound. This project seeks to aid in the search for morels …

Effects Of Two Different Concentrations Of Miracle-Gro Solution On Wisconsin Fast Plant Growth, Peter Francissen, Joseph Gonziorek, Katherine Morgan, Danielle Deering

Celebration of Learning

Wisconsin Fast Plant (Brassica Rapa, Brassicaceae) seeds were planted in three six-celled planting chambers. The chambers were filled with standard potting soil under continuous grow-lux lighting. A week after germination, one planting chamber (E1) was supplied with the recommended Miracle-Gro fertilizer solution. Our second experimental chamber (E2) was supplied with 1.5x the eight was 60.4. Our t-tests showed that the height of the control plants vs. E1 was significant (P=.010563), for control plants vs. E2 it was even more significant (P=.008813). However, for E1 vs. E2, our data was insignificant (P=.318883). Our hypothesis was that supplying the Wisconsin Fast Plants …

The Effects Of Two Levels Of Salinity On Wisconsin Fast Plants, Megan M. Janssen, Emily Geison, Tiffany Bertoni, Matthew Zimmerman

Celebration of Learning

Wisconsin Fast Plant (Brassica rapa, Brassicaceae) seeds were planted in three, six-celled planting containers filled with potting soil and put beneath a continuous grow-lux light. One week after sprouting, one container (E1) was put into a separate tray filled with 0.5% NaCl solution, another container (E2) was put into a separate tray filled with 1.0% NaCl solution, and the third container was left in regular tap water. At seven-day intervals thereafter, the height of all plants was recorded, and the numbers of leaves and flowers were recorded. By week four of recording data, the average height (mm) of the control …

Celebration of Learning

The Wisconsin Fast Plant, Brassica rapa (Brassicaceae) seeds were planted in three, six-celled containers and were filled with standard potting soil under continuous grow-lux lighting. After the first week of plant growth, E1and E2 were placed in a separate trays and given 1.0 and 1.5x the recommended amount of Miracle-Gro formula, respectively. The control was left in tap water and all were kept in 1 cm of solution. Every seven days the plants’ heights were recorded, and the total number of flowers were counted. By the fourth week, the average height of the control plants was 105.7 mm, of the …

Long-Term Sandhills Prairie Responses To Precipitation, Temperature, And Cattle Stocking Rate, John A. Guretzky, Cheryl Dunn, Heidi L. Hillhouse

Department of Agronomy and Horticulture: Faculty Publications

Understanding of Sandhills prairie, the most expansive sand dune region stabilized by perennial grasses in the Western Hemisphere, is limited by lack of long-term vegetation data. We used a 26-year dataset to evaluate Sandhills prairie responses to yearto- year variation in precipitation, temperature, and cattle stocking rate. Basal cover, a measurement that is constant seasonally and used to detect long-term changes in bunchgrass vegetation, was measured in 38–40 permanent plots positioned along four transects spanning 769 ha from 1979 to 2007. Across this period, total basal cover averaged 2.4 % and was dominated by warm-season grasses (81.1 %). Schizachyrium scoparium …

Book Reviews: A Chorus Of Cranes: The Cranes Of North America And The World. Paul A. Johnsgard (With Photographs By Thomas D. Mangelsen, And Drawings And Maps By Paul A. Johnsgard)., John G. Sidle

The Prairie Naturalist

Once again, naturalist and author Paul A. Johnsgard invites us to dance and chorus with cranes, and to appreciate their beauty and links to another species, Homo sapiens. A Chorus of Cranes is about natural history but also is a plea for conservation, which is a common foreword, prologue, preface, and/or epilogue of many wildlife books. It is vintage Paul Johnsgard text from preface to epilogue, words that emerge after a long wade through countless papers and reports, and a prolonged career of observation and reflection in the field. He has beckoned us before to cherish cranes and the natural …

Resource Selection By Black-Backed Woodpeckers (Picoides Arcticus) And American Three-Toed Woodpeckers (P. Dorsalis) In South Dakota And Wyoming, Sean R. Mohren, Mark A. Rumble, Chadwick P. Lehman, Stanley H. Anderson

The Prairie Naturalist

Black-backed woodpeckers (Picoides arcticus, [BBWO]) and American three-toed woodpeckers (P. dorsalis, [ATTW]) are uncommon inhabitants of conifer forests and are sympatric in some areas, including the Black Hills. Both species exhibit genetic characteristics associated with isolated populations, are species of special management concern, and for which data are lacking concerning populations and habitats. We developed resource selection models of forest vegetation within 500 m radius plots (78.5 ha) for BBWOs and ATTWs to provide forest managers with stand-level information to estimate how forest management might affect habitat for these species in the Black Hills. Relative probability of selection by BBWOs …

Missing The Point, Christopher N. Jacques

The Prairie Naturalist

Greetings GPNSS members! I hope summer finds you well and enjoying the Great Plains in some way, whether that be getting your hands dirty with field work, a reprieve from the office, anxiously awaiting the crappie bite at your favorite lake, or taking a much needed vacation. For those who enjoy cooler temperatures, summer heat and humidity are challenging and even the most seasoned field biologists among us are tested when fighting the conditions doing what we are passionate about. I personally prefer the fall and winter seasons, though also look forward to summer because it offers me a break …

The Science Of Open Spaces: Theory And Practice For Conserving Large, Complex Systems. Charles G. Curtin., Michelle L. Hellman, Caleb P. Roberts, Hannah Birge, Zachary Warren, Craig R. Allen

The Prairie Naturalist

The phrase “open spaces,” may bring to mind expansive tracts of prairie, rangeland, or even desert, stretching lonely and unchanged to the horizon. Open spaces also could conjure open oceans or interstitial rural lands between urbanized hubs, dotted with farms, fields, and woodlands. In an abstract sense, open spaces could represent gaps in human understanding or blank spaces on a map. In his book The Science of Open Spaces, landscape ecologist Charles Curtin combines all these perspectives, expanding the definition of “open spaces” to multi-layered and multi-scaled complex systems that are “greater than the sum of their parts.” He populates …

Book Review: Better Birding: Tips, Tools, And Concepts For The Field. George L. Armistead And Brian L. Sullivan., Stephen J. Dinsmore

The Prairie Naturalist

George Armistead and Brian Sullivan have written a book whose aim is to provide birders with a solid foundation upon which to develop better birding skills. They advocate a more holistic approach to bird identification than simply looking at a set of predetermined field marks. To that end, their approach combines traditional field identification approaches with behavioral and habitat cues, as well as natural history, to broaden bird identification skills. This is not the first book to make a case for looking at bird identification more broadly, although their specific approach seems unique. The authors offer constructive criticism of “traditional” …

Mink Predation Of Brown Trout In A Black Hills Stream, Jake Davis, Jerry W. Wilhite, Steven R. Chipps

The Prairie Naturalist

In the early 2000’s, declines in the brown trout (Salmo trutta) fishery in Rapid Creek, South Dakota, caused concern for anglers and fisheries managers. We conducted a radio telemetry study in 2010 and 2011 to identify predation mortality associated with mink, using hatchery-reared (2010) or wild (2011) brown trout. Estimated predation rates by mink (Mustela vison) on radio-tagged brown trout were 30% for hatchery fish and 32% for wild fish. Size frequency analysis revealed that the size distribution of brown trout lost to predation was similar to that of other, radio-tagged brown trout. In both years, a higher proportion of …

Evaluating The Myth Of Allelopathy In California Blue Gum Plantations, Kristen Marie Nelson

Master's Theses

It is widely accepted that allelopathy is not only significant, but more or less singular, in the inhibition of understory vegetation in California Eucalyptus globulus (blue gum) plantations. However, there is no published documentation of allelopathy by blue gums against California native species. Here, we present evidence that germination and early seedling growth of five California native species are not inhibited by chemical extracts of blue gum foliage, either at naturally-occurring or artificially concentrated levels. In the greenhouse, seeds were germinated in field-collected soil from mature blue gum plantations and the adjacent native, coastal scrub communities. In petri plates, seeds …

Assessing Genetic Variation Of Rocky Mountain Bighorn Sheep At Elk Mountain, Brynn L. Parr, Rebeca L. Juarez, Jonathan A. Jenks

The Prairie Naturalist

The bighorn sheep (Ovis canadensis canadensis) herd occupying the Elk Mountain Region of South Dakota and Wyoming was established in 2001 with 20 individuals. An additional 7 ewes were released in 2004. The population increased to approximately 120 individuals in 2009, but subsequently declined to an estimated 80 individuals. Because of the low population size used to establish the herd and relative isolation of the Elk Mountain Region, potential factors associated with the population decline included reduced genetic diversity. Our objectives were to: 1) assess genetic diversity, 2) measure effective population size (Ne), and 3) compare the genetic diversity of …

Keys To Lichens Of North America, Revised And Expand- Ed. Irwin M. Brodo (Photographs By Sylvia Duran Sharnoff And Stephen Sharnoff; Drawings By Susan Laurie-Bourque)., Caleb A. Morse

The Prairie Naturalist

It would be hard to overestimate the importance of the 2001 publication of Lichens of North America (hereafter LNA) by Irwin Brodo, Silvia Duran Sharnoff, and Stephen Sharnoff (Brodo et al. 2001). Beautifully illustrated, LNA included both an excellent overview to lichenology—including such diverse topics as chemistry, ecology, ethnolichenology, and specimen preparation—and descriptions of more than 800 of the common and charismatic lichens of North Ameri- ca. It is the rare book that provides a good introduction to the discipline, while serving as an essential tool for lichenologists. LNA is frequently cited in journals as an authoritative source on spot …

Varmints And Victims: Predator Control In The Ameri- Can West. Frank Van Nuys., Phil Mastrangelo

The Prairie Naturalist

Having recently retired after 30+ years working in the field of human-wildlife conflicts, including predator conflicts with livestock, I looked forward to reading Varmints and Victims: Predator Control in the American West by Frank Van Nuys. As a wildlife biologist with an interest in the history of wildlife management in North America, I was further intrigued by the subject matter selected by Van Nuys.

In the book’s introduction, Van Nuys explains how the issue of mountain lion (Puma concolor) management in his home state of South Dakota sparked his interest in further exploring the history of predators and their management …
