    The first 50 years of the Prairie Naturalist reside on the shelves of libraries and personal collections. The articles and notes published over those years provide invaluable knowledge about Great Plains biota, communities, conservation, and landscape ecologies. Awareness of the wealth of information in those 50 print volumes has been limited, relying on references from other published papers or the limited number of articles that have been made available online by authors. This index serves as resource for individuals to digitally tap into the information published since 1994. This index, together with the first 25-year index, serves to complement the growing number of Prairie Naturalist volumes that are being available online at the University of Nebraska’s Digital Commons (https://digitalcommons.unl.edu/tpn/). This index to the Prairie Naturalist is the third to be completed. The first, covering the first 10 volumes was compiled by Virginia Steinhaus. That material was incorporated by editor Dr. Paul Kannowski into the second index that covered the first 25 years of the Prairie Naturalist (1969-1993). That index is available online as a searchable PDF at the University of Nebraska’s Digital Commons under 1997, the year it was published (https://digitalcommons.unl.edu/tpn/index.4.html#year_1997). This index covers the second 25 years, 1994–2018. Along with regular articles, notes, and book reviews, it also includes two special issues: Lesser Prairie Chickens (2000, 32[3]) and the Proceedings of the 23rd North American Prairie Conference (2014, 42[Special Issue]). Journal editors during 1994–2018 include Dr. Paul Kannowski (1969–1995), Dr. Elmer Finck (1996–2009), and Dr. Christopher Jacques (2009–2018). The journal is a product of the Great Plains Natural Science Society, formerly the North Dakota Natural Science Society. The society’s name was changed in 2004 to better reflect the greater breadth of regional interests and journal content. The structure used here follows that established in the first 25-year index, with some modifications. The Author Index provides full citations for articles, notes, book reviews, and editorials; the end of that section includes Corrections, cross-referenced to the original paper. The following sections provide shorter citations (author, year, volume:pages) for readers to refer back to the Author Index. Books Reviewed are listed by book author, year, and book title, with a short citation to the book review in the Author Index. The Subject Index was developed using key words and additional information representative of papers’ content. Some decisions to include additional subject words were subjective but always focused on core findings and study objectives. Locations included in the Geographic Index represent the location of actual field work or findings. The Taxonomic Index includes scientific and common names of taxa studied. One of the challenges in compiling this section was the changes in taxonomy since the papers were published. A cross-reference is provided from the original taxonomy to the current taxonomy, as determined in January 2022 with online authorities, to the best of my ability using information in the original article. I have benefited from the contributions of various individuals during the development of this index. Larry Igl provided constructive comments during development and final drafts. I appreciate the assistance of several individuals who reviewed the Taxonomic Index sections or provided valuable guidance: Andre DeLorme (invertebrates), Keith Geluso (amphibians, reptiles, mammals), David Lambeth (birds), and Steve Chipps (fishes)

    Response of Vegetation in Open and Partially Wooded Fens to Prescribed Burning at Seney National Wildlife Refuge

    The health and function of northern peatlands, particularly for fens, are strongly affected by fire and hydrology. Fens are important to several avian species of conservation interest, notably the yellow rail (Coturnicops noveboracensis). Fire suppression and altered hydrology often result in woody encroachment, altering the plant community and structure. Woody encroachment and its effects on biodiversity have become an increasing concern in the conservation and management of plant communities. This study evaluated the effects of spring and summer prescribed burns on the plant community, cover, and structure in open and partially wooded fens at Seney National Wildlife Refuge, Michigan, using a before-after-control-impact design. Paired, 1-hectare blocks were established in two fen areas, C3 and Marsh Creek, and data were collected for 2 years before burning (2006–7) and 3 years after burning (2008–10). We used generalized linear mixed models and ordination to assess differences among four treatments: C3 control, C3 spring burn (May 2008), Marsh Creek control, and Marsh Creek summer burn (July 2008); results from a block burned under drier conditions in July 2007 also are reported. Variables include water depth; litter depth; graminoid height; species richness and diversity; percent cover of plant taxa, mosses, and open area; shrub height, number of patches, and cover; and visual obstruction readings. The 2008 prescribed burns were done under moderate fire conditions, whereas the 2007 summer burn on one block was done under high fire conditions because of prolonged drought. We identified 104 plant taxa over the 5 years and noted differences between C3 and Marsh Creek communities. We examined data for effects of treatment, year, and year × treatment interactions for percent open and the 28 most common taxa. Most differences among treatments were related to natural differences in the plant community and hydrology between the two areas rather than fire effects; year effects were likely related to annual differences in water conditions. We detected few effects of spring burning in C3, even in the same year of burning. In Marsh Creek, most treatment effects were in 2008, when data were collected within 3 weeks of burning. Some fire effects there, however, persisted one to two growing seasons (2009, 2010) and two to three growing seasons in the block burned in the more intense summer 2007 fire. Effects of burning on shrub measures were more apparent on summer-burned blocks, but most measures returned to preburn conditions by 2010. Our results demonstrate the heterogeneity of plant community and environmental conditions of fens within and among years and the interactions of water conditions with burning. The results also demonstrate that neither single spring nor summer burning under moderate fire conditions are effective in setting back woody cover. Maintaining more open conditions in fens may require different approaches to water management, more frequent fires, more aggressive fire management, or a combination of tools to control woody cover

    List of Previous Proceedings of the North American Crane Workshops: Suggested citation formats PREFACE Memorials: ROBERT H. HORWICH 1940-2017; WILLIAM A. LISHMAN 1939-2017; THEODORE A. BOOKHOUT 1931-2018; JAMES T. HARRIS 1950-2018 CONTENTS Front and back covers The North American Crane Working Group (NACWG) is an organization of professional biologists, aviculturists, land managers, non-professional crane enthusiasts, and others interested in and dedicated to the conservation of cranes and crane habitats in North America. Our group meets approximately every 3 years to exchange information pertaining to sandhill cranes and whooping cranes and occasionally reports about some of the other cranes species. The NACWG held the 14th North American Crane Workshop in Chattanooga, Tennessee, on 12-13 January 2017 preceded on 11 January by a social at the Chattanooga Zoo, and followed by field trips to nearby Hiwassee Wildlife Refuge on 14 January and to Wheeler National Wildlife Refuge (near Decatur, Alabama) on 15 January. The field trips coincided with the crane festivals held annually at both sites. Board member David Aborn did an outstanding job with local planning and arrangements. There were 70 registrants. The scientific program consisted of 37 oral and 14 poster presentations on North American cranes. Both field trip locations are major wintering areas for sandhill cranes and whooping cranes, and unusually warm weather resulted in great viewing. The L. H. Walkinshaw Crane Conservation Award, NACWG’s highest honor, was presented to Tom Stehn (Frontispiece). A special Award of Recognition was presented to local resident Ken Dubke, who was instrumental in Hiwassee Wildlife Refuge becoming a major sandhill crane migration stopover and wintering area and in raising historical awareness that led to creation of the Cherokee Removal Memorial. For many years Ken organized the annual Sandhill Crane and Cherokee Heritage Festival. During the NACWG business meeting, members voted to increase the size of the NACWG Board of Directors to 11 members, including a student representative; these currently include President Richard Urbanek, Vice-president Sammy King, Treasurer Barry Hartup, Secretary Daryl Henderson, David Aborn, Tommy Michot, Glenn Olsen, and new members George Archibald, Megan Brown, Paige Smith, and Hillary Thompson. The papers in these Proceedings represent 8 presentations from the workshop and 10 manuscripts submitted later. Abstracts of oral and poster presentations for which a paper is not published here are included at the end of the volume. Papers submitted for publication in the Proceedings are peer-reviewed according to scientific journal standards. We thank the following referees for their contribution to the quality of this volume: Ken F. Abraham, Jeb A. Barzen, David A. Brandt, Daniel P. Collins, Timothy A. Dellinger, Bruce D. Dugger, Taylor A. Finger, David L. Fronczak, Jeremy E. Guinn, Matthew A. Hayes, Jerome J. Howard, Gary L. Ivey, Eileen M. Kirsch, Susan N. Knowles, Anne E. Lacy, James R. Lovvorn, Robert G.

Stehn, Eva K. Szyszkoski, Josh L. Vest, Scott J. Werner, Brook J. Wilke, Jeffrey R. Wozniak, and Sara E. Zimorski. Daryl S. Henderson and Sara E. Zimorski were instrumental in final editing and proofing. This volume retains use of the genus Grus for 4 crane species (sarus, brolga, white-naped, and sandhill). Until analysis of nuclear DNA supports reclassification, the NACWG will continue to endorse the conclusions of Krajewski et al. (2010, Auk 127:440-452) and Krajewski (2018, Chapter 2 in Whooping Cranes: Biology and Conservation, Academic Press). Krajewski (personal communication, 2016) considers recent reclassification to the genus Antigone to be premature

    NESTING ECOLOGY OF SANDHILL CRANES AT GRAYS LAKE, IDAHO

    Get PDF
    We examined the nesting ecology of greater sandhill cranes (Grus canadensis tabida) at Grays Lake, Idaho during 1997-99 to detennine the effects of nest-site characteristics and land use on crane nest success. These are preliminary results from 3 years of a 4-year study. Crane nests were located in portions of the Grays Lake basin from early May through late June each year (n = 131 in 1997; n = 131 in 1998; n = 143 in 1999). Apparent nest success varied among years (54% in 1997, 71% in 1998, and 53% in 1999; overall average of 59%). We estimate that 10% of nests found in 1999 were renests. Most crane nests were located in baltic rush/spikerush (Juncus balticus/Eleocharis sp.; 46% of nests), semi-wet meadow (19%), and bulrush/cattail (Scirpus sp./Typha sp.; 19%) plant communities; 62% of nests during early May were in:;; 12 cm of water. As indicated by plant community, water depths at nests, and nest isolation rankings, nest success tended to be higher where nests were in relatively deep water (ca. \u3e40 em) and were relatively isolated from access by mammalian predators. Nest success rates during 1997-99 were lower than those recorded in 1950-51 (90%, n = 107; Steel 1952) and 1970-71 (78%, n = 308; Drewien 1973). A variety offactors likely contribute to lower nest success, including changing predator communities over the past 30-40 years. Differences among years in our study may be affected by changing availability of alternate prey. Small mammal populations and crane nest success were the highest in 1998. Water-level management, relating to cranes and other waterbird populations, plant communities, and ecosystem function, is an emerging issue for land managers in the Grays Lake basin

    SANDHILL CRANE ABUNDANCE AT GRAYS LAKE, IDAHO

    We initiated a study on the breeding ecology of greater sandhill cranes (Grus canadensis tabida) in the Grays Lake basin ofIdaho in 1997. Interest in the status of crane populations at Grays Lake is high; consequently, we present preliminary information on estimated size of the population, changes since the 1970s, and potential environmental factors involved. Drewien (1973) counted an average of549 cranes in the spring and estimated 250 nesting pairs in 1970-71. Number of nesting pairs reportedly increased 33% (to 332) by 1982 in response to intensive management, then declined 40-60% by 1996 (Drewien 1997, and Homocker Wildlife Institute, personal communication). During 1998-99, spring counts averaged 736 cranes (34% increase from 1970-71). Among 44 survey units that were searched during both studies, nest densities increased in 27, decreased in 13, and remained unchanged in 4. Nest success declined from 78% in 1970-71 to 59% in 1997-99. We estimated that renesting accounted for 10% of nests in 1999. Fall staging populations were similar between the early 1970s (n = 1313) and late 1990s (n = 1370), but well below peak counts of the 1980s (often \u3e3000). Factors potentially influencing the crane populations at Grays Lake include habitat management, climate (drought), predator populations, manipulation of marsh water levels, agricultural practices, baiting, and disturbance
