A Dietary Variety: Analyzing The Impacts Of Diverse Vs Worm-Exclusive Diets On The Blanding’S Turtle (Emydoidea Blandingii), Caitlin F. Copenhaver
A Dietary Variety: Analyzing The Impacts Of Diverse Vs Worm-Exclusive Diets On The Blanding’S Turtle (Emydoidea Blandingii), Caitlin F. Copenhaver
Honors Theses
The endangered Blanding’s turtle (Emydoidea blandingii) is a species with a generally diverse diet in their freshwater wetland habitats; they consume prey such as crayfish and snails. In captivity, these options often become more limited due to logistical reasons. As ex situ conservation efforts such as captive rearing and head-starting are becoming more popular for this species, it will be important to gain more insight on how these more limited diets might affect these turtles. This study describes a comparison between diets in six captive Blanding’s turtles from September to November of 2023, with three turtles receiving only …

Biodiversity loss is a major global challenge and minimizing extinction rates is the goal of several multilateral environmental agreements. Policy decisions require comprehensive, spatially explicit information on species’ distributions and threats. We present an analysis of the conservation status of 14,669 European terrestrial, freshwater and marine species (ca. 10% of the continental fauna and flora), including all vertebrates and selected groups of invertebrates and plants. Our results reveal that 19% of European species are threatened with extinction, with higher extinction risks for plants (27%) and invertebrates (24%) compared to vertebrates (18%). These numbers exceed recent IPBES (Intergovernmental Platform on Biodiversity …
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, …
American Burying Beetle, Plant Richness, And Soil Property Responses To Collapse Of Juniperus Virginiana Woodlands With Fire, Alison Ludwig
American Burying Beetle, Plant Richness, And Soil Property Responses To Collapse Of Juniperus Virginiana Woodlands With Fire, Alison Ludwig
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Grasslands are declining in the Great Plains due to land use changes, woody plant encroachment, and loss of historic fire cycles. Prescribed burn associations have utilized prescribed fire to collapse invading woodlands and allow the restoration of grasslands. This fire is considered “extreme” because it is capable of changing the structure and function of an ecosystem. Our study site is the Loess Canyons Experimental Landscape, a long-term, ecoregion-scale experiment to apply prescribed fire across the region to restore grasslands. The Nebraska Natural Legacy Project established the Loess Canyons ecoregion as a Biologically-Unique Landscape in 2005 with the state’s wildlife action …
Summer To Autumn Population Of Wild Eumaeus Atala On The Ft. Lauderdale Campus Of Nova Southeastern University, Alexandra M. Lens
Summer To Autumn Population Of Wild Eumaeus Atala On The Ft. Lauderdale Campus Of Nova Southeastern University, Alexandra M. Lens
Mako: NSU Undergraduate Student Journal
Eumaeus atala is an endangered tropical butterfly native to the Caribbean and some parts of Florida, USA. Following population reductions primarily due to habitat loss, E. atala populations are now increasing due to conservation efforts of its cycad host plants, especially Zamia integrifolia (coontie). The purpose of this study was to observe, document, and measure the population of wild E. atala on the Ft. Lauderdale, Florida campus of Nova Southeastern University where landscaping use of host plants supports a natural population of E. atala. Forty-four host plants located in two different sites were observed for 14 weeks. One site …
Vertebrates On The Brink As Indicators Of Biological Annihilation And The Sixth Mass Extinction, Gerardo Ceballos, Paul R. Ehrlich, Peter H. Raven
Vertebrates On The Brink As Indicators Of Biological Annihilation And The Sixth Mass Extinction, Gerardo Ceballos, Paul R. Ehrlich, Peter H. Raven
Harold W. Manter Laboratory: Library Materials
The ongoing sixth mass species extinction is the result of the destruction of component populations leading to eventual extirpation of entire species. Populations and species extinctions have severe implications for society through the degradation of ecosystem services. Here we assess the extinction crisis from a different perspective. We examine 29,400 species of terrestrial vertebrates, and determine which are on the brink of extinction because they have fewer than 1,000 individuals. There are 515 species on the brink (1.7% of the evaluated vertebrates). Around 94% of the populations of 77 mammal and bird species on the brink have been lost in …
Protecting Biodiversity On National Forests: The Evolution And Implementation Of Forest Planning Regulations, Anna Wearn
Protecting Biodiversity On National Forests: The Evolution And Implementation Of Forest Planning Regulations, Anna Wearn
Graduate Student Theses, Dissertations, & Professional Papers
In 2012, the U.S. Forest Service (USFS) promulgated new forest planning regulations that significantly altered national forest management. One of the most controversial and important advancements was the inclusion of what were meant to be stronger biodiversity protections. An analysis of USFS’s rationale in revising the biodiversity regulations provides insights into how to interpret the substantively and procedurally new ecosystem and species protections. Examining this regulatory history reveals three key changes to the manner in which national forests are required to manage and monitor biodiversity: 1) a greater reliance on science to inform planning, 2) a new emphasis on ecological …
Effects Of Rearing Environment On Behavior Of Captive-Reared Whooping Cranes, Christy L. Sadowski, Glenn H. Olsen, M. Elsbeth Mcphee
Effects Of Rearing Environment On Behavior Of Captive-Reared Whooping Cranes, Christy L. Sadowski, Glenn H. Olsen, M. Elsbeth Mcphee
Proceedings of the North American Crane Workshop
Whooping cranes (Grus americana) are 1 of the most endangered bird species in North America. In 1999 the Whooping Crane Eastern Partnership was formed to establish a migratory population of whooping cranes in eastern North America. These efforts have been extremely successful in terms of adult survival but reproductive success post-release has been low. One hypothesis developed to explain such low reproductive success is that captive-rearing techniques fail to prepare the birds to be effective parents. Captive-reared whooping cranes at the U.S. Geological Survey, Patuxent Wildlife Research Center, Laurel, Maryland, are either reared by humans in crane costumes …
Mississippi Sandhill Crane Conservation Update 2014-2016, Scott G. Hereford, Angela J. Dedrickson
Mississippi Sandhill Crane Conservation Update 2014-2016, Scott G. Hereford, Angela J. Dedrickson
Proceedings of the North American Crane Workshop
To manage crane habitat during 2014-2016, 5,826 ha were treated with prescribed burns, 298 ha of woody vegetation were removed, 94 ha of invasive plants were chemically treated, and 8 ha of crops were planted. There were 247 predators removed. We acclimated and released 29 captive-reared juveniles. We began testing drones (unmanned aerial systems [UAS]), to locate nests. We detected an average of 34 nests per year with 6 fledglings each year. The December 2016 population was 129 cranes, up 9% from the previous 3 years.
Where Can Wolves Live And How Can We Live With Them?, L. David Mech
Where Can Wolves Live And How Can We Live With Them?, L. David Mech
USGS Northern Prairie Wildlife Research Center
In the contiguous 48 United States, southern Canada, and in Europe, wolves (Canis lupus) have greatly increased and expanded their range during the past few decades.They are prolific, disperse long distances, readily recolonize new areas where humans allow them, and are difficult to control when populations become established.Because wolves originally lived nearly everywhere throughout North America and Eurasia, and food in the form of wild and domestic prey is abundant there, many conservation-minded people favor wolves inhabiting even more areas.On the other hand, wolves conflict in several ways with rural residents who prefer fewer wolves. This article discusses …

Distribution, Densities, And Ecology Of Siberian Cranes In The Khroma River Region Of Northern Yakutia In Northeastern Russia, Inga P. Bysykatova, Gary L. Krapu, Nicolai I. Germogenov, Deborah A. Buhl
Proceedings of the North American Crane Workshop
The Siberian crane (Grus leucogeranus) is the third rarest crane species in the world with a breeding range now centered on 3 core areas and a buffer zone in the arctic of northern Yakutia in northeastern Russia. During 16 July-2 August 2009, we undertook ground surveys within the Khroma River core breeding area, surrounding buffer zone, and lands lying to the west of the known breeding range to estimate densities and determine habitat use and social status of Siberian cranes. A total of 142 Siberian cranes were sighted (including 55 pairs) at 54 locations with 32 cranes (including 13 pairs) …
The Utility Of Census Or Survey For Monitoring Whooping Cranes In Winter, Bruce H. Pugesek, Thomas V. Stehn
The Utility Of Census Or Survey For Monitoring Whooping Cranes In Winter, Bruce H. Pugesek, Thomas V. Stehn
Proceedings of the North American Crane Workshop
We discuss recent changes in the monitoring program for endangered whooping cranes (Grus americana) on their winter habitat in Texas. A 61-year annual census was replaced in the winter of 2011-2012 with a distance sampling procedure. Justification for the change was, in part, based on criticism of the previous methods of counting cranes and the assessment of crane mortality on the wintering grounds. We argue here that the arguments, methods, and analyses employed to discount the census procedure and mortality estimates were applied incorrectly or with flawed logic and assertions. We provide analysis and logical arguments to show …

Freshwater Mussels Of Virginia (Bivalvia: Unionidae): An Introduction To Their Life History, Status And Conservation, Jess W. Jones
Virginia Journal of Science
With 77 species, the mussel fauna of Virginia is one of the most diverse in the United States. Fifty-four species or ~70% of the state’s mussel fauna occurs in the rivers of the upper Tennessee River basin, especially in the Clinch and Powell rivers of southwestern Virginia. An additional 23 species reside in rivers of the Atlantic Slope, including the Potomac, Rappahannock, York, James and Chowan basins, and in the New River, a major tributary to the Ohio River. A total of 39 species or 51% of Virginia’s mussel fauna is listed as federally endangered, state endangered or state threatened. …
Carnivore Diet Identification Through Scat And Genetic Analysis In Namibia, Africa, Alicia J. Walsh
Carnivore Diet Identification Through Scat And Genetic Analysis In Namibia, Africa, Alicia J. Walsh
Honors Theses and Capstones
Worldwide the cheetah population is declining making them Africa’s most endangered large cat. Namibia, Africa currently has the largest population of cheetahs in the world. During the summer of 2014, I did scat analysis of carnivores on the property of the Cheetah Conservation Fund (CCF) in Namibia in order to better understand the predators that compete with the cheetah and how the ecosystem works as a whole. I worked at CCF for nine weeks to analyze the diets of carnivores in the area through genetic and scat analysis. Analyzing carnivore feces would ultimately identify the diet of various carnivores in …

Marine molluscs represent an estimated 23% of all extant marine taxa, but research into their conservation status has so far failed to reflect this importance, with minimal inclusion on the authoritative Red List of the International Union for the Conservation of Nature (IUCN). We assessed the status of all 632 valid species of the tropical marine gastropod mollusc, Conus (cone snails), using Red List standards and procedures to lay the groundwork for future decadal monitoring, one of the first fully comprehensive global assessments of a marine taxon. Three-quarters (75.6%) of species were not currently considered at risk of extinction owing …

From Energy Gradient And Natural Selection To Biodiversity And Stability Of Ecosystems, Bo Deng
Department of Mathematics: Faculty Publications
The purpose of this paper is to incorporate well-established ecological principles into a foodweb model consisting of four trophic levels --- abiotic resources, plants, herbivores, and carnivores. The underlining principles include Kimura's neutral theory of genetic evolution, Liebig's Law of the Minimum for plant growth, Holling's functionals for herbivore foraging and carnivore predation, the One-Life Rule for all organisms, and Lotka-Volterra's model for intraand interspecific competitions. Numerical simulations of the model led to the following statistical findings: (a) particular foodwebs can give contradicting observations on biodiversity and productivity, in particular, all known functional forms -- - positive, negative, sigmoidal, and …

Mississippi Sandhill Crane Conservation Update, 2003-2005, Scott G. Hereford, Tracy E. Grazia
Proceedings of the North American Crane Workshop
The Mississippi sandhill crane (Grus canadensis pulla) is an endangered non-migratory subspecies found on and near the Mississippi Sandhill Crane National Wildlife Refuge in southeastern Mississippi. From 2003 to 2005, conservation efforts for the recovery of this population included management activities such as protection and law enforcement, restocking, predator management, farming, prescribed burning, mechanical vegetation removal, hydrological restoration, pest plant management, and education. To maintain open savanna, 1842 hectares were burned annually, with 38% during the growing season. To restore open savanna, 506 hectares of woody vegetation were removed using mechanical methods. To bolster the population, we released 17-25 captive-reared …

Past, Present, And Hypothetical Methods For Crane Reintroduction And Migration, David H. Ellis
Past, Present, And Hypothetical Methods For Crane Reintroduction And Migration, David H. Ellis
Proceedings of the North American Crane Workshop
In the early 1980’s the technique of releasing yearling parent-reared cranes was perfected with the Mississippi sandhill crane (Grus canadensis pulla). In the late 1980’s, we discovered that hand-reared yearlings could also be released with good expectation of survival in both migratory and nonmigratory situations. In the mid-1990’s, efforts expanded in many directions including (1) the use of various types of motorized vehicles to lead migrations, (2) the release of juveniles one by one into wild flocks in autumn or winter, and (3) the release of adult pairs. Here I outline new and proven techniques and those likely …
