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 …
Color-Band Identification System Of The Reintroduced Eastern Migratory Whooping Crane Population, Richard Urbanek
Color-Band Identification System Of The Reintroduced Eastern Migratory Whooping Crane Population, Richard Urbanek
Proceedings of the North American Crane Workshop
A reintroduction of whooping cranes (Grus americana) migrating between Wisconsin and the southeastern U.S. was initiated in 2001. A color-band system to uniquely identify individuals was necessary for monitoring and evaluation of that population. The system provided 336 individual unduplicated color combinations consisting of 3 base and 1 additional colors on plastic bands. The band combination on 1 leg carried a VHF transmitter and provided additional information on hatch year. Bands on the other leg were either small bands that were part of a permanent code or they were temporary and supported a remotely monitored (satellite or cellular) …

Examining Whooping Crane Breeding Season Foraging Behavior In The Eastern Migratory Population, Hillary L. Thompson, Anik Levac, Megan J. Fitzpatrick
Proceedings of the North American Crane Workshop
Agricultural fields may provide an important supplementary foraging habitat for whooping cranes (Grus americana) in the reintroduced Eastern Migratory Population (EMP). We developed methods and gathered preliminary data regarding whooping crane foraging efficiency and habitat use to better understand the use of agricultural fields by breeding cranes. We generated a simple null hypothesis that cranes would spend more time in the habitat type (wetlands vs. agricultural fields) in which they were able to obtain a higher foraging efficiency to maximize food intake, along with several alternative hypotheses pertaining to reasons cranes may prefer wetlands or agricultural fields during …
Working With Land Managers To Identify And Manage Potential Stopover Locations For Whooping Cranes, Chester A. Mcconnell
Working With Land Managers To Identify And Manage Potential Stopover Locations For Whooping Cranes, Chester A. Mcconnell
Proceedings of the North American Crane Workshop
Whooping cranes (Grus americana) of the Aransas-Wood Buffalo Population migrate 4,000 km twice each year between their nesting grounds in northern Canada and their wintering grounds on the Texas Gulf Coast. During migration, whooping cranes must land at suitable ponds or wetlands to feed or rest. The Whooping Crane Recovery Plan calls for the protection and management of whooping crane stopover locations within the migration corridor. While major stopover areas have been protected, many other smaller sites remain to be identified. Moreover, the Recovery Plan offers no specific entity to protect and manage the latter. To address these …
Testing Three Chemicals For Deterring Crop Damage By Cranes, Anne E. Lacy, Jeb A. Barzen, Andrew P. Gossens
Testing Three Chemicals For Deterring Crop Damage By Cranes, Anne E. Lacy, Jeb A. Barzen, Andrew P. Gossens
Proceedings of the North American Crane Workshop
Damage to planted corn seed by cranes has the potential to cause great economic loss in areas where both intersect. In 2000 the International Crane Foundation (ICF) tested limonene (LIM), methyl anthranilate (MA), and 9,10-anthraquinone (AQ) as possible replacements for the insecticides lindane and diazinon that had been used as deterrents to cranes damaging corn seed and seedlings. LIM, MA, and AQ lowered germination rates (down to 85, 90, and 92%, respectively) as compared to a germination rate of 96% in untreated corn. A 1.0% solution of AQ was effective as a crane deterrent, while LIM and MA were not. …
Antipredator Training For Captive-Reared Mississippi Sandhill Crane Chicks, Jerome J. Howard, Richard A. Dunn, Scott G. Hereford
Antipredator Training For Captive-Reared Mississippi Sandhill Crane Chicks, Jerome J. Howard, Richard A. Dunn, Scott G. Hereford
Proceedings of the North American Crane Workshop
Captive-bred Mississippi sandhill cranes (Grus canadensis pulla) suffer from low recruitment in nature, and poor nest defense ability may significantly contribute to the problem. We hypothesized that a lack of opportunities for social learning by young birds prior to release inhibits the development of appropriate nest defense in later life. Here we report the results of preliminary experiments on conditioning of antipredator behavior in young birds prior to release using predator models. Observing agonistic displays by either costumed technicians or parent birds toward a model raccoon (Procyon lotor) promoted aggressive displays to a wild raccoon, but …

Osteoarthritis In The Pelvic Limb Of Captive Cranes, Barry K. Hartup, Savannah J. Lauer, Alyson R. Manthei
Proceedings of the North American Crane Workshop
We conducted an epidemiological study of osteoarthritis (OA) among the 15 captive crane species managed at the International Crane Foundation from 1973 to 2016. A retrospective review of 714 medical records found 37 cases of OA in 13 species of cranes and a corresponding period prevalence of OA of 5%. An analysis of the living captive crane flock as of 1 October 2016 (n = 115) found 12 active cases of OA (a point prevalence of 10%), and there was a statistical association between geriatric age classification (i.e., advanced age) and the presence of OA (P < 0.01). The mean age of cranes with OA was 14 years greater than cranes without the disease (P < 0.001). The prevalence estimates of OA from this review were somewhat lower than that from study of museum specimens, but this study similarly identified the tarsal joint as the predominant location of OA lesions in cranes.

Natural History Of The Southern Bog Lemming In Southeastern Virginia, Robert K. Rose
Natural History Of The Southern Bog Lemming In Southeastern Virginia, Robert K. Rose
Biological Sciences Faculty Publications
The isolated subspecies of Southern Bog Lemming of southeastern Virginia, Synaptomys cooperi helaletes, has been studied extensively since its "rediscovery" in the Great Dismal Swamp in 1980. Multiple studies using pitfall traps, starting in the Great Dismal Swamp National Wildlife Refuge and then extending elsewhere in southeastern Virginia and adjacent northeastern North Carolina, have revealed lemmings to be much more widespread and often more common than previously believed, with their presence now confirmed as far west as Surry and Sussex counties, about 30 km east of Petersburg, Virginia. When present, lemmings often are among the most numerous members of …
Native Grass Cover Influences Forb Density In Cp-42 Pollinator Plantings, Alyssa Burgert, Laura Jackson
Native Grass Cover Influences Forb Density In Cp-42 Pollinator Plantings, Alyssa Burgert, Laura Jackson
Undergraduate Student Work
In recent years, pollinator populations have greatly declined due to a large decrease in habitat. In order to combat this decline, government programs have provided farmers with incentives to convert cropland to pollinator habitat.1 Farmers are required to plant at least 9 insect-pollinated species, with 3 species each blooming in early, middle and late summer. Any grasses must be native and comprise no more than 25% of the seed mix.2 Because of the high cost of forb seed and relatively low cost of grasses, we aimed to evaluate the effectiveness of this seed mix strategy. We predicted that …
Muskrats, James E. Miller
Muskrats, James E. Miller
Wildlife Damage Management Technical Series
The muskrat (Ondatra zibethicus) is a common, semi-aquatic rodent native to the United States (Figure 1). It spends its life in aquatic habitats and is well adapted for swimming.
Although muskrats are an important part of native ecosystems, their burrowing and foraging activities can damage agricultural crops, native marshes and water control systems, such as aquaculture and farm ponds and levees. Such damage can significantly impact agricultural crops like rice that rely on consistent water levels for growth.
Muskrats also cause damage by eating agricultural crops, other vegetation, and crayfish, mussels and other aquaculture products. Loss of vegetation …
Wild Turkeys, James E. Miller
Wild Turkeys, James E. Miller
Wildlife Damage Management Technical Series
Like other bird and mammal species whose populations have been restored through conservation efforts, wild turkeys (Figure 1) are treasured by many recreationists and outdoor enthusiasts. Wild turkeys have responded positively to wildlife habitat and population management. In some areas, however, their increased populations have led to increased damage to property and agricultural crops, and threats to human health and safety. Turkeys frequent agricultural fields, pastures, vineyards and orchards, as well as some urban and suburban neighborhoods. Because of this, they may cause damage or mistakenly be blamed for damage. Research has found that despite increases in turkey numbers and …
Microbial Diversity In The Thermal Springs Within Hot Springs National Park, E. Taylor Stone, Richard Murray, Matthew D. Moran
Microbial Diversity In The Thermal Springs Within Hot Springs National Park, E. Taylor Stone, Richard Murray, Matthew D. Moran
Journal of the Arkansas Academy of Science
The thermal water systems of Hot Springs National Park (HSNP) in Hot Springs, Arkansas exist in relative isolation from other North American thermal systems. The HSNP waters could therefore serve as a unique center of thermophilic microbial biodiversity. However, these springs remain largely unexplored using culture-independent next generation sequencing techniques to classify species of thermophilic organisms. Additionally, HSNP has been the focus of anthropogenic development, capping and diverting the springs for use in recreational bathhouse facilities. Human modification of these springs may have impacted the structure of these bacterial communities compared to springs left in a relative natural state. The …

Persistence Of Stream Restoration With Large Wood, Redwood National And State Parks, California, Diedra L. Rodriguez
Persistence Of Stream Restoration With Large Wood, Redwood National And State Parks, California, Diedra L. Rodriguez
Cal Poly Humboldt theses and projects
The conservation and recovery of anadromous salmonids (Oncorhynchus sp.) depend on stream restoration and protection of freshwater habitats. In-stream large wood dictates channel morphology, increases retention of terrestrial inputs such as organic matter, nutrients and sediment, and enhances the quality of fish habitat. Historic land use/land cover changes have resulted in aquatic systems devoid of large wood. Restoration by placement of large wood jams is intended to restore physical and biological processes. An important question for scientists and restoration managers, in addition to the initial effectiveness of restoration, is the persistence and fate of large wood installations. In this …

Understanding Subterranean Variability: The First Genus Of Bathynellidae (Bathynellacea, Crustacea) From Western Australia Described Through A Morphological And Multigene Approach, Giulia Perina, A. I. Camacho, Joel Huey, Pierre Horwitz, Annette Koenders
Research outputs 2014 to 2021
The number of subterranean taxa discovered in the north of Western Australia has substantially increased due to the requirements for environmental surveys related to mining development. Challenges in estimating subterranean biodiversity and distributions are related to lack of knowledge of taxa with convergent morphological characters in a largely unobservable ecosystem setting. An integrated approach is warranted to understand such complexity.
Bathynellidae occur in most Australian aquifers, but only one species has been described so far, and the group lacks a reliable taxonomic framework. A new genus and one new species from the Pilbara region of Western Australia, Pilbaranella ethelensis, …

Research outputs 2014 to 2021
Heat waves have profoundly impacted biota globally over the past decade, especially where their ecological impacts are rapid, diverse, and broad-scale. Although usually considered in isolation for either terrestrial or marine ecosystems, heat waves can straddle ecosystems of both types at subcontinental scales, potentially impacting larger areas and taxonomic breadth than previously envisioned. Using climatic and multi-species demographic data collected in Western Australia, we show that a massive heat wave event straddling terrestrial and maritime ecosystems triggered abrupt, synchronous, and multi-trophic ecological disruptions, including mortality, demographic shifts and altered species distributions. Tree die-off and coral bleaching occurred concurrently in response …

Pollinator Power: Supporting Bees Through Ecoregion Specific Planting Guides, Maya Thomas
Pollinator Power: Supporting Bees Through Ecoregion Specific Planting Guides, Maya Thomas
Scripps Senior Theses
The pollination of flowering crops by bees is an invaluable ecosystem service that supports biodiversity and much of the global agricultural system. Pollinators move pollen between the male structures of a plant to the female structures of a plant of the same species. This fertilizes the female plant, which then produces the next generation. This process also provides the pollinator with the nectar or pollen it needs to survive. While some plants transfer pollen through different means, the majority of plants need help from pollinators to reproduce. Depending on the means of pollination, pollination can be classified as abiotic or …
Disarming “Nature” As A Weapon: A Queer Ecosemiotic Reimagining Of Futurity And Environmental Ethics Through Memoir, Sam Lauer
Master’s Theses
In this thesis, I posit that the need for an active, conscious, and radical queering of ecocriticism as a literary and cultural theory has arisen in light of the postmodern problematization of “nature” and the “natural,” along with the queerness of society, culture, and science. The way we understand “nature” (in life and in texts), whether of physical environments, inherent selfhood, or normalcy, begs to be appropriately informed by discourses and realities of queerness in order for both social and environmental healing to take place. I have analyzed three works of queer creative nonfiction—memoirs—to illuminate the ways in which the …

Are bacteria capable of undergoing oxygenic photosynthesis under low-light conditions inside of caves? Inside of an Australian cave, Chlorophyll f was recently discovered. This chlorophyll pigment was found to demonstrate the capability for photosynthesis, suggesting that Chlorophyll f extends the spectrum of usable light needed for oxygenic photosynthesis (Lars, 2015). Due to the findings in this study, a team went to Carlsbad Caverns to see if there were any bacteria capable of undergoing oxygenic photosynthesis under low light.

How do traits vary across the tree of life? Our ability to address this question is diminished if: A taxonomic group has a poorly sampled phylogeny, a species goes extinct before their systematic position is resolved, or a trait is inadequately characterized for detailed studies. In the current era of mass extinction, it is imperative to not only accelerate species discovery through traditional studies in taxonomy and expeditionary research, but also to increase rescue efforts for all types of data before poorly understood species and potentially undescribed traits are lost. Here, an integrative taxonomic approach was used and novel methods …

Conserving All The Pollinators: Variation In Probability Of Pollen Transport Among Insect Taxa, Diane L. Larson, Jennifer L. Larson, Deborah A. Buhl
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
As concern about declining pollinator populations mounts, it is important to understand the range of insect taxa that provide pollination services. We use pollen transport information acquired over three years in two habitats at Badlands National Park, South Dakota, USA, to compare probabilities of pollen transport among insect taxa and between sexes of bees. Sampling was conducted on 1-ha plots, eight in sparse vegetation (May–October samples; N = 74 surveys) and 12 in wheatgrass prairie vegetation (June–July samples; N = 87 surveys). Insects contacting reproductive parts of flowers were netted, placed individually into tubes charged with ethyl acetate, then transferred …

Effective monitoring of native bee populations requires accurate estimates of population size and relative abundance among habitats. Current bee survey methods, such as netting or pan trapping, may be adequate for a variety of study objectives but are limited by a failure to account for imperfect detection. Biases due to imperfect detection could result in inaccurate abundance estimates or erroneous insights about the response of bees to different environments. To gauge the potential biases of currently employed survey methods, we compared abundance estimates of bumblebees (Bombus spp.) derived from hierarchical distance sampling models (HDS) to bumblebee counts collected from fixed‐area …

Abstract
Neonchocotyle violantei n. sp. (Monogenea: Hexabothriidae) infects the gill of the Atlantic guitarfish, Pseudobatos lentiginosus (Rhinopristiformes, Rhinobatidae) from littoral waters of Celestún, Yucatán, Mexico. It is assigned to Neonchocotyle because it has, among other features, an asymmetrical haptor, a seminal receptacle, a smooth oötype, and an egg with two elongate filaments. It differs from Neonchocotyle pastinacae, the only congener, by having a small body (821 long by 315 wide, length to width = 2.6:1), two pairs of microhooks between the haptoral appendix suckers, extracaecal (submarginal) vaginal pores, and 5-9 testes. This is the first record of a species …

Abstract
The helminthological examination of nine individuals of Aetobatus cf. narinari (spotted eagle ray; raya pinta; arraia pintada) revealed the presence of an undescribed species of cestode of the genus Acanthobothrium. The stingrays were collected from four locations in México: Laguna Términos, south of Isla del Carmen and the marine waters north of Isla del Carmen and Champotón, in the State of Campeche, and Isla Holbox, State of Quintana Roo. The new species, nominated Acanthobothrium marquesi, is a category 3 species (i.e, the strobila is long, has more than 50 proglottids, the numerous testicles greater than 80, and has …

This accomplishment has been overlooked both by biologists and historians, but it should rank among the most significant accomplishments of the expedition. The results of this inventory continue to inform us today about environmental, faunal, and floral changes along the Missouri River in an area that is known to be an ecotone between the deciduous forests of the …
