Inventory Of The Central Mixed-Grass Prairie Ecoregion Of Kansas And Nebraska, Hillary Loring, Mike Bullerman, Kelly Kindscher
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
An inventory of potential high quality mixed-grass prairie ranches and large properties within the Central Mixed-Grass Prairie Ecoregion of Kansas and Nebraska was conducted in the spring and summer of 1999. Emphasis during the inventory was placed on identification of relatively intact landscapes. Significant ranches within those untilled landscapes were visited. An interview of the owners or managers of those properties was coupled with a survey of the vegetation. Assessments of quality were based on species composition, continuity of ground cover, observations of livestock impact, and viability of the community types present.
The objectives of this study were to:

Woody Vegetation Expansion And Continuing Declines In Open Channel Habitat On The Platte River In Nebraska, Paul J. Currier
Woody Vegetation Expansion And Continuing Declines In Open Channel Habitat On The Platte River In Nebraska, Paul J. Currier
Proceedings of the North American Crane Workshop
Aerial videography in 1988 and 1994 of the same selected segments of the Big Bend reach of the Platte River in central Nebraska was compared. During this 6-year period, channel area declined 4 to 41 % (median 26%). In river segments where the channel had already narrowed significantly and at sites where channel habitat is actively managed declines were less (17-18%). These substantial changes occurred during a time that included a relatively low flow period (1990-92). Flows during the summer gertttination and establishment period (mid-May through August) for cottonwood (Populus deltoides) and willow (Salix spp.), the …
Parasite Biodiversity And Emerging Pathogens: A Role For Systematics In Limiting Impacts On Genetic Resources, Eric P. Hoberg
Parasite Biodiversity And Emerging Pathogens: A Role For Systematics In Limiting Impacts On Genetic Resources, Eric P. Hoberg
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Emergence of pathogenic organisms continues as a threat to overall biodiversity and genetic resources. Macroparasites including helminths constitute a potential threat to economically important resources in agriculture and conservation biology. Limitation of this threat can be achieved through survey and inventory for biodiversity and the application of systematics to understand the host range , biogeography and history of faunas. Systematics constitutes the foundation for recognition of endemic and introduced elements of faunas and the basis for predicting the behavior of pathogens introduced to new ecological settings or host groups. The basis for emergence of pathogens has both a deep historical …

A Study Of The Lichens At Rocky Branch Nature Preserve, Clark County, Illinois, Eric B. Grunder
Masters Theses
In 1971, a graduate student at Eastern Illinois University, James E. Wiedman, studied the lichen flora of Rocky Branch Nature Preserve, Clark County, Illinois. During his study he collected, identified, and recorded a total of 64 lichen species. Since 1971, Rocky Branch Nature Preserve has experienced a dramatic increase in use by people and a concomittant decline in the quality of lichen habitats. In order to assess the decline of suitable lichen habitats and the reduction of lichen species a second study of the lichens at Rocky Branch Nature Preserve was undertaken. As part of this study, ten habitat sites …

The Challenge And Opportunity Of Recovering Wolf Populations, L. David Mech
The Challenge And Opportunity Of Recovering Wolf Populations, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
The gray wolf once inhabited a wide variety of habitats throughout most of the northern hemisphere north of 20°N latitude. Because the animal preyed on livestock and competed with humans for wild prey, it was extirpated from much of its range outside of wilderness areas. Environmental awareness in the late 1960s brought for the wolf legal protection, increased research, and favorable media coverage. The species has increased in both Europe and North America, is beginning to reoccupy semiwilderness and agricultural land, and is causing increased damage to livestock. Because of the wolfs high reproductive rate and long dispersal tendencies, the …

Getting The Lay Of The Land: Introducing North American Native Grasslands, Anthony Joern, Kathleen H. Keeler
School of Biological Sciences: Faculty Publications
The expected catastrophic extinction of species (already under way in many places) will alter the planet’s biological diversity so profoundly that, at the known rate of extinction, it will take millions of years to recover. Yet few ecologists study extinction. Indeed, very little ecology deals with any processes that last more than a few years, involve more than a handful of species, and cover an area of more than a few hectares. The temporal, spatial and organizational scales of most ecological studies are such that one can read entire issues of major journals and see no hint of impending catastrophe. …

Unobstructed Visibility At Whooping Crane Roost Sites On The Platte River, Nebraska, Craig A. Faanes
Unobstructed Visibility At Whooping Crane Roost Sites On The Platte River, Nebraska, Craig A. Faanes
Proceedings of the North American Crane Workshop
Unobstructed visibility is an important component of whooping crane (Grus americana) roosting habitat. Recent habitat modeling efforts suggest that unobstructed horizontal visibility is suitable at a minimum of 335 m. Unobstructed upstream and downstream visibility is also an important part of whooping crane roosting habitat, but quantification of that parameter has not been reported previously, or incorporated into species models. Data from the Platte River suggest that a minimum of 732 m of unobstructed upstream and downstream visibility is needed at whooping crane roost sites.
Contaminant Residues In Sandhill Cranes Killed Upon Striking Powerlines In Central Nebraska, Timothy E. Fannin
Contaminant Residues In Sandhill Cranes Killed Upon Striking Powerlines In Central Nebraska, Timothy E. Fannin
Proceedings of the North American Crane Workshop
In 1989 and 1990, 58 sandhill cranes (Grus canadensis) were collected along the central Platte River in Nebraska during a study of mortality caused by powerline impact. Brains were assayed for acetylcholinesterase activity; gut contents were analyzed for residues of 25 organophosphate and 6 carbamate compounds; and livers were analyzed for 20 inorganics (including lead, mercury, and boron) and 22 organochlorine chemicals. Brain acetylcholinesterase activities appeared to be within normal ranges, and no measurable organophosphate or carbamate residues were found in the gut contents of 5 birds with the lowest brain enzyme activities. Heptachlor epoxide, oxychlordane. p,p' -DDE, …
Sandhill Crane Collisions With Power Lines In Southcentral Nebraska, John P. Ward, Stanley H. Anderson
Sandhill Crane Collisions With Power Lines In Southcentral Nebraska, John P. Ward, Stanley H. Anderson
Proceedings of the North American Crane Workshop
Sandhill crane (Grus canadensis) collisions with power lines were studied in southcentral Nebraska in 1986 and 1987. Approximately 596 km of power lines were surveyed for dead cranes in 1986, and 210 km of power lines in 1987. A total of 135 dead cranes were located. Cranes collided 4 times more with transmission lines than distribution lines, although distribution lines were twice as abundant. We believe cranes collided with the static wires on the transmission lines. Juveniles and Canadian sandhill cranes (G.c. rowani) had a higher probability of colliding with power lines than other age groups …
Whooping Crane Riverine Roosting Habitat Suitability Model, Jerry W. Ziewitz
Whooping Crane Riverine Roosting Habitat Suitability Model, Jerry W. Ziewitz
Proceedings of the North American Crane Workshop
Water development interests on the Platte River in Nebraska and recognition of the importance of this river as migratory bird habitat have prompted studies to determine how much water is needed to maintain wildlife habitat values. The whooping crane (Grus americana) is one of many species that use the Platte. A model was developed to quantify the relationship between river discharge and roosting habitat suitability for whooping cranes, designed to accommodate the data collection and hydraulic simulation techniques of the Instream Flow Incremental Methodology. Results of the model indicate that optimum roosting habitat conditions in the Big Bend …

Proceedings of the North American Crane Workshop
An epizootic of eastern equine encephalitis (EEE) virus infection in 1984 resulted in death for 7 of 39 captive whooping cranes (Grus americana) at the Patuxent Wildlife Research Center. This represented the first known whooping crane deaths associated with this arboviral disease and posed a serious risk to the continued propagation of this endangered species. Subsequent research and surveillance procedures initiated to prevent EEE viral infections in captive whooping cranes included vector surveillance and control, virus surveillance through use of sentinel birds, immunoassays for rapid detection of EEE virus antigen in bird sera and in mosquitoes, and testing …
Factors Influencing The Future Of Whooping Crane Habitat On The Platte River In Nebraska, Craig A. Faanes
Factors Influencing The Future Of Whooping Crane Habitat On The Platte River In Nebraska, Craig A. Faanes
Proceedings of the North American Crane Workshop
Lands along 86 km of the Platte River in Nebraska were designated by the U.s. Department of Interior as critical habitat for the endangered whooping crane (Grus americana) in 1978. The designation established the legal basis for the continued protection of lands critical to the survival and recovery of whooping cranes. Currently there are 14 federal, state, and local water projects planned for the Platte River system. If completed, total withdrawal would be about 80% of the remaining 30% of the original flow. In this paper I summarize those projects and discuss their potential impact on whooping crane habitat. …

Characteristics Of Whooping Crane Roost Sites In The Platte River, Craig A. Faanes, Douglas H. Johnson, Gary R. Lingle
Proceedings of the North American Crane Workshop
The Big Bend of the Platte River in centraJ Nebraska provides important migration habitat for whooping cranes (Grus americana). River profiles were obtained at 23 confumed nocturnal roost sites occupied by whooping cranes during 1983 -90. Whooping cranes selected roost sites that had shallower water depths than at unused sites. All but 4 roosts were located in channels wider than 150 m; roost sites were an average of 27.8 % of the channel width from the nearer shore. Nearly 90% of the roost sites had a trench of deeper water on both sides. Proper management of the Platte …
History And Economic Impact Of Crane-Watching In Central Nebraska, Gary R. Lingle
History And Economic Impact Of Crane-Watching In Central Nebraska, Gary R. Lingle
Proceedings of the North American Crane Workshop
The first documentation of the Platte and North Platte rivers' importance to sandhill cranes (Grus canadensis) dates from the late 1800's. Except for a few ornithologists, it was not until the mid-1970's that crane-watching became popular. During the last 10 years, this interest has become a multi-million dollar tourist industry that attracts people from around the globe who seek to witness this vernal spectacle of half a million cranes. More than half of the former riverine habitat has been abandoned by the cranes, largely because of irrigation and hydropower projects that drain the river and enable forests to …
Relationship Of Channel Maintenance Flows To Whooping Crane Use Of The Platte River, Craig A. Faanes, David B. Bowman
Relationship Of Channel Maintenance Flows To Whooping Crane Use Of The Platte River, Craig A. Faanes, David B. Bowman
Proceedings of the North American Crane Workshop
Periodic high flows in the Platte River are necessary to scour vegetation and redistribute sediment in the stream channel. Peak and mean annual flows have been reduced by as much as 70% from pre-development times, but channel maintenance flows still occur, although at a much reduced frequency and magnitude of occurrence. Use of the Platte River by migrant whooping cranes (Grus americana) in recent years appears to be related to the recent occurrence of flows in excess of 8,000 cfs for 5 or more consecutive days.

Distribution, Habitats, And Taxonomy Of Ruppia Maritima L. And R. Occidentalis S. Watson In Nebraska, Robert B. Kaul
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Specimens of Ruppia from all eleven Nebraska counties in which it is known fall into two groups: R. occidentalis in alkaline Sandhills waters and R. maritima in saline waters of the Platte River Valley and Lancaster County. Ruppia occidentalis is distinguished by its more robust size; redspotted leaves and stems; terete, entire, obtuse leaves; 4-8(9) carpels; and by two elliptic white spots on its endocarp, among other characteristics. Ruppia maritima is more delicate and unspotted; the leaves are oblate in section, sub-apically denticulate, and acute-acuminate; the carpels are 3 or 4, and the endocarp spots are nearly circular. Both species …
