An Examination Of The Eastern Nebraska And Western Iowa Flash Flood Event Of 6-7 August 1999, Catherine M. Zapotocny
An Examination Of The Eastern Nebraska And Western Iowa Flash Flood Event Of 6-7 August 1999, Catherine M. Zapotocny
NOAA Technical Reports and Related Materials
Flash flooding occurs each summer in eastern Nebraska and western Iowa. While 10-inch rains are extraordinary, it is not uncommon to have at least one excessive rain event during the annual convective season. A significant flash flood occurred in east central Nebraska and western Iowa the night of August 6, 1999 into the morning of August 7, 1999. Antecedent hydrologic conditions limited the loss of life, however considerable property damage resulted as the heavy rain fell over the urbanized areas in eastern Nebraska and western Iowa.
Several flash flood ingredients came together over the area. These meteorological factors are typical …

Prairie Dogs, Gary Witmer, Jon Grant, Kendra Cross
Prairie Dogs, Gary Witmer, Jon Grant, Kendra Cross
Wildlife Damage Management Technical Series
Prairie dogs (Cynomys spp.) occur throughout the prairie states of middle North America from Mexico northward into Canada. They occupy a variety of habitats from prairies to high mountain valleys and sage brush-dominated deserts. The most common species is the black-tailed prairie dog (Cynomys ludovicianus; Figure 1). Prairie dogs are considered a “keystone species.” They provide habitat for many other native, grassland species. Prairie dogs live in colonies or “towns” that can span hundreds to thousands of acres. Depending on the species, their presence is evident by their burrow system. Despite the many ecosystem benefits prairie dogs provide by modifying …
Blanding’S Turtle (Emydoidea Blandingii): Species Conservation Assessment, Melissa J. Panella, Colleen Rothe-Groleau
Blanding’S Turtle (Emydoidea Blandingii): Species Conservation Assessment, Melissa J. Panella, Colleen Rothe-Groleau
Nebraska Game and Parks Commission: Publications
The primary goal in development of at-risk species conservation assessments is to compile biological and ecological information that may assist conservation practitioners in making decisions regarding the conservation of species of interest. The Nebraska Natural Legacy Project recognizes the Blanding’s turtle (Emydoidea blandingii) as a Tier 1 at-risk species. Some general management recommendations are made here regarding Blanding’s turtles; however, conservation practitioners will need to use professional judgment to make specific management decisions based on objectives, location, and a multitude of variables. This resource was designed to share available knowledge of this at-risk turtle that will aid in the decision-making …
Insect Biodiversity Of Select Areas In The Western Suburbs Of Chicago, Bradley Dawson
Insect Biodiversity Of Select Areas In The Western Suburbs Of Chicago, Bradley Dawson
Department of Entomology: Distance Master of Science Projects
Introduction
Insects make up an integral part of the landscape in North America and across the world. They occupy a myriad of niches in food webs, function as predators and prey, and provide environmental services like pollination of flowering plants and decomposition of dead animal carcasses and fecal matter. They take part in ecosystems that are often delicately balanced, and so conservation is often a worthwhile effort in areas that would otherwise be trampled by human activity. In the western suburbs of Chicago, Illinois where I reside, there is a mix of both heavily developed areas as well as some …

The Taxonomic Report of the International Lepidoptera Survey
Subsequent to the significant accomplishment of biological control of Opuntia weeds in Australia, the larvae of the cactus moth, Cactoblastis cactorum (native to parts of South America), were released in many countries for the biological control of native Opuntia species (Simmonds and Bennett, 1966). Inauspiciously, larvae were also released in the Caribbean, where the moth spread naturally and by the human support all over the region (García-Turudi et al., 1971). Its enhanced dissemination rate and the biological potential for invasiveness, suggests that the cactus moth is likely to become an invasive pest of Opuntia in the Southeast United States, Mexico, …
Life History And Ecology Of The San Emigdio Blue Butterfly (Lepidoptera: Lycaenidae), Gregory R. Ballmer
Life History And Ecology Of The San Emigdio Blue Butterfly (Lepidoptera: Lycaenidae), Gregory R. Ballmer
The Taxonomic Report of the International Lepidoptera Survey
The San Emigdio blue butterfly, Plebulina emigdionis (Grinnell, 1905), occurs in small, scattered colonies in and near the southwestern Mojave Desert of California. Colonies depend on a symbiotic relationship with the ant Formica francoueri (Bolton), and occur only where the ant’s range (primarily in more mesic cis-montane habitats) narrowly overlaps that of the butterfly’s more widely distributed Atriplex larval hosts in more xeric habitats. Colonies of P. emigdionis are often localized around a few host plants and, therefore, sensitive to habitat changes due to anthropocentric causes and environmental stochasticity. The biology, ecology, and status of known colonies of P emigdionis …

Drivers Of Annual Fledging In The Mississippi Sandhill Crane Population 1991-2018, Henry W. Woolley, Scott G. Hereford, Jerome J. Howard,
Drivers Of Annual Fledging In The Mississippi Sandhill Crane Population 1991-2018, Henry W. Woolley, Scott G. Hereford, Jerome J. Howard,
Proceedings of the North American Crane Workshop
We studied trends in nesting, number of chicks fledged annually, and their environmental and biotic drivers in the wild population of Mississippi sandhill cranes (Grus canadensis pulla) on Mississippi Sandhill Crane National Wildlife Refuge during 1991-2018. Population size, number of nests, and number of chicks fledged annually increased slowly but significantly over the course of the study. Increases in population size were related to both number of wild-reared chicks fledged annually and number of captive-reared chicks released each year, but wild-reared chicks had significantly higher survivorship than captive-reared chicks. Hurricanes transiently raised mortality rates but only Hurricane Katrina …
Black Fly Survey Of A Whooping Crane Reintroduction Area In Eastern Wisconsin, Richard P. Urbanek, Peter H. Adler
Black Fly Survey Of A Whooping Crane Reintroduction Area In Eastern Wisconsin, Richard P. Urbanek, Peter H. Adler
Proceedings of the North American Crane Workshop
Nest desertion due to harassment by black flies (Simulium annulus and S. johannseni) during incubation has been a major factor inhibiting success of the reintroduced Eastern Migratory Population of whooping cranes (Grus americana). To avoid this problem, which was prevalent in the core reintroduction area in central Wisconsin, the Whooping Crane Eastern Partnership changed the primary reintroduction area to eastern Wisconsin in 2011. However, a 2010 assessment of black flies in that area had concentrated predominantly on the southern portion of the new area. In 2017-2018, we collected the first samples of black flies in Green …

Twenty-Year Status Of The Eastern Migratory Whooping Crane Reintroduction, Hillary L. Thompson, Nicole M. Gordon, Darby P. Bolt, Jadine R. Lee, Eva K. Szyszkoski
Proceedings of the North American Crane Workshop
Since the 10-year status update in 2011, the first parent-reared whooping cranes (Grus americana) were released in the Eastern Migratory Population, the ultralight program (UL) ended, and cranes were released at new sites in eastern Wisconsin. During 2011-2020, 117 captive-reared whooping cranes were released; 75 costume-reared (35 in UL and 40 in the Direct Autumn Release program) and 42 parent-reared. There were no significant differences in 1- or 3-year survival rates based on rearing technique or release site. The population size remained at about 100 cranes during 2010-2018 but then decreased during 2018-2020 due to a reduced number …
Observations Of Whooping Crane Parental Provisioning Of Chicks, Glenn H. Olsen
Observations Of Whooping Crane Parental Provisioning Of Chicks, Glenn H. Olsen
Proceedings of the North American Crane Workshop
Crane chicks are dependent on parent birds for provisioning during the first few months of life, but no study has examined this provisioning in detail. In 2014 research staff at the U.S. Geological Survey, Eastern Ecological Science Center (formerly Patuxent Wildlife Research Center), in Laurel, Maryland, made multiple observations of parent whooping cranes (Grus americana) feeding or interacting with their chick during the 3 months from hatching to fledging. Both parents participated in the feeding of the chick and only 1 chick was raised by each pair of parent whooping cranes. Initially feeding frequency was low (0-20 times …
Vigilance Of Nesting Whooping Cranes In Juneau County, Wisconsin, Nicole M. Gordon, Darby P. Bolt, Hillary L. Thompson
Vigilance Of Nesting Whooping Cranes In Juneau County, Wisconsin, Nicole M. Gordon, Darby P. Bolt, Hillary L. Thompson
Proceedings of the North American Crane Workshop
Vigilance plays an important role in the detection of possible threats and reducing the risk of predation, including during the incubation period. We examined the visual vigilance of incubating whooping cranes (Grus americana) in Juneau County, Wisconsin, during the 2019 nesting season. We deployed 9 trail cameras and tagged crane presence and behavior in 32,801 photos which were used in our analysis. We assessed individual nest and environmental variables and their effects on vigilant behavior of incubating cranes using linear mixed-models. Vigilant behavior was defined by a posture in which the crane’s head was up, neck was erect, …

How Stressful Is It To Move? Whooping Crane Glucocorticoid Response During Facility Transfer, Megan E. Brown, Christopher Martin, Christopher Crowe, Sprina Lui, Nucharin Songsasen,
Proceedings of the North American Crane Workshop
The ability to transfer animals between different facilities for genetic management is a critical component to the success of any cooperatively managed captive animal population despite the high cost and the need for a high level of coordination in logistical planning. Two issues of concern are the magnitude of potential stress responses incurred during shipment of adult cranes to a new facility and the duration of elevated glucocorticoid production during the acclimation periods. The objectives of this project were to assess adrenal responses of whooping cranes (Grus americana) during transfer from the Patuxent Wildlife Research Center (PWRC) to …

Initial Evaluation Of Cyclic Adenosine Monophosphate Enzyme Immunoassay For Use With Crane Semen Samples, Megan E. Brown, Kim Boardman, Katie L. Edwards
Proceedings of the North American Crane Workshop
The management of ex situ and in situ populations of many wildlife species requires detailed knowledge of a species’ reproductive biology. For species such as cranes, where artificial insemination is a critical component of ex situ management strategies, understanding normal sperm function is especially important. Previous research has shown that captive cranes exhibit highly variable production and quality of semen samples produced by individual males and high levels of variation of cell concentration and motility across different species. Cyclic adenosine monophosphate (cyclic AMP) has been implicated in regulating sperm function, such as cell motility, and may affect an individual’s ability …
Summary Of Mortality Among Captive Cranes At The International Crane Foundation: 2000-2020, Barry K. Hartup, Robert Phillips
Summary Of Mortality Among Captive Cranes At The International Crane Foundation: 2000-2020, Barry K. Hartup, Robert Phillips
Proceedings of the North American Crane Workshop
We reviewed mortalities of captive cranes at the International Crane Foundation (ICF) between 2000 and 2020 to provide broad insights into contemporary factors affecting the collection’s health and survival. Sixty-three deaths were documented in 13 of 15 crane species held in the ICF collection. The mean annual mortality during the study was 2.6% and the mean age (±SD) at death was 28.4 (±12.7) years. The overall total number of deaths of males and females was similar, but there was an association between sex and death of adult versus geriatric (>25 years) cranes (P < 0.01); males were more likely to die at geriatric age than females. Deaths were commonly associated with chronic health and management problems (n = 44, 79%) versus …
Mississippi Sandhill Crane Conservation Update 2017-2019, Scott G. Hereford, Angela J. Dedrickson
Mississippi Sandhill Crane Conservation Update 2017-2019, Scott G. Hereford, Angela J. Dedrickson
Proceedings of the North American Crane Workshop
To manage crane habitat on the Mississippi Sandhill Crane National Wildlife Refuge during 2017-2019, 5,822 ha were treated with prescribed burns, 648 ha of woody vegetation were removed, 97 ha of invasive plants were chemically treated, and 1.2 ha of crops were planted. Mississippi sandhill crane (Grus canadensis pulla) use responded to habitat treatment; 348 of 349 VHF radio locations were in treated areas. There were 316 target predators removed. Eighteen captive-reared juveniles were acclimated and released. We detected an average of 38 nests per year, including a record 40 nests in 2019. Fifteen chicks fledged in 2019, …
