Genetic Protocols For Dna Extraction From White-Tailed Deer Cast Antlers To Confirm Individuality, Zach Carter, Brian C. Peterson, Casey W. Schoenebeck, Kimberly A. Carlson
Genetic Protocols For Dna Extraction From White-Tailed Deer Cast Antlers To Confirm Individuality, Zach Carter, Brian C. Peterson, Casey W. Schoenebeck, Kimberly A. Carlson
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
White-tailed deer (Odocoileus virginianus) are the most sought-after deer species in America. The antlers of mammals, such as deer, are one of the fastest regenerative tissues in the world and are grown and naturally cast every year. Research on cast antlers have been used for a variety of purposes including population comparisons and impacts of deer health due to climatic stressors. When investigating cast antlers, it is important to confirm individuality of match sets in addition to antlers of the same individual between years. Therefore, individuality must be confirmed genetically, and protocols must be developed and established to …
Can Financialization Save Nature? The Case Of Endangered Species, Diane-Laure Arjalies, Delphine Gibassier
Can Financialization Save Nature? The Case Of Endangered Species, Diane-Laure Arjalies, Delphine Gibassier
Business Publications
The current biodiversity loss is dramatic. Over the past 50 years, more than 68% of the mammals, birds, amphibians, reptiles, and fish on earth have disappeared, putting the planet's survival and its inhabitants – including human beings – at risk (WWF, 2020). Financialization, or the transformation of nature into financial assets, is increasingly proposed as a solution to the biodiversity crisis. Proponents of financialization believe that assigning a monetary value to nature will incentivize human beings to protect habitats and their species. This article offers a four-mechanism model of nature’s financialization, explaining why it is virtually impossible to financialize nature. …
Reconstructing The Ecological Relationships Of Late Cretaceous Antarctic Dinosaurs And How Functional Tooth Morphology Influenced These Relationships, Ian D. Broxson
2022 Symposium
The Sandwich Bluff Formation of the James Ross Basin of Antarctica has recently yielded a group of five late Cretaceous dinosaurs that lived contemporaneously with each other, a first for Antarctica. These five dinosaurs include fragmentary remains of two differently sized elasmarian ornithopods, a possible megaraptor, a hadrosaur, and a nodosaur. In this study we will construct a model of the ecological relationships of late Cretaceous Antarctica. Additionally, we will look at what specific factors allowed this group of four herbivores and a carnivore to coexist in a restricted locality and what niches were filled by each species. Methods to …

Effects Of Cottonseed Meal Containing Gossypol On Testis Physiology In Boars, Kristin Ryan
Animal Science Undergraduate Honors Theses
Feral hogs are an invasive species found in 35 U.S. states without an effective control method to limit their population growth. According to a 2019 survey of 467 landowners in Arkansas, feral hogs caused an estimated $12 million in damages (Cook, 2019). While there are current control methods such as hunting and trapping, 65% of the feral hog population must be eliminated in a specific area to prohibit population growth (Cook, 2019). It is theorized that gossypol, a phenolic compound known to negatively impact reproductive function in other species, could cause sterility in boars. In this preliminary research study, 21 …

Ontogenetic Drivers Of Morphological Evolution In Monitor Lizards And Allies (Squamata: Paleoanguimorpha), A Clade With Extreme Body Size Disparity, Carlos J. Pavón-Vázquez, Damien Esquerré, J. Scott Keogh
Ontogenetic Drivers Of Morphological Evolution In Monitor Lizards And Allies (Squamata: Paleoanguimorpha), A Clade With Extreme Body Size Disparity, Carlos J. Pavón-Vázquez, Damien Esquerré, J. Scott Keogh
Publications and Research
Background
Heterochrony, change in the rate or timing of development, is thought to be one of the main drivers of morphological evolution, and allometry, trait scaling patterns imposed by size, is traditionally thought to represent an evolutionary constraint. However, recent studies suggest that the ontogenetic allometric trajectories describing how organisms change as they grow may be labile and adaptive. Here we investigated the role of postnatal ontogenetic development in the morphological diversification of Paleoanguimorpha, the monitor lizards and allies, a clade with extreme body size disparity. We obtained linear and geometric morphometric data for more than 1,600 specimens belonging to …

Impact Of Covid-19 On Aviation-Wildlife Strikes Across Europe, Isabel C. Metz, Marta Giordano, Dionysios Ntampakis, Marianna Moira, Anneke Hamann, Rosanne Blijleven, Jürgen J. Ebert, Alessandro Montemaggiori
Human–Wildlife Interactions
Collisions between aircraft and wildlife (i.e., wildlife strikes) pose a serious threat toward the safety of aircraft, its crew, and passengers. The effects of COVID-19 related travel restrictions on wildlife strikes are unknown. With this study, we aim to address this information gap by assessing the changes of wildlife hazard management performance across European airports during the lockdown period (e.g., period of reduced operations and borders closure in spring 2020). We also sought to raise awareness of the importance of wildlife strike prevention in times of reduced operations. The objective of our study was to compare wildlife strike data before …

Human–Wildlife Interactions
Mitigation translocation remains a popular conservation tool despite ongoing debate regarding its utility for population conservation. To add to the understanding of the effectiveness of mitigation translocation, in 2017 and 2018 we monitored a population of protected common chuckwallas (Sauromalus ater) following translocation away from the area of construction of a new highway near the South Mountains, Phoenix, Arizona, USA. We removed chuckwallas from the construction right-of-way, paint-marked and pit-tagged them, and then released them in a nearby municipal preserve. We deployed very high frequency radio-telemetry transmitters on a sub-sample of 15 translocated adult chuckwallas. We monitored the …
Understanding Caribou Population Cycles, Jack R. St. John
Understanding Caribou Population Cycles, Jack R. St. John
Undergraduate Theses, Professional Papers, and Capstone Artifacts
The complex population dynamics of caribou (Rangifer tarandus) were studied to determine the patterns of their population cycles and the processes driving them. It is well established, via previous archaeological research and Indigenous knowledge, that large migrating caribou herds found in and around the tundra at northern latitudes experience population boom and busts roughly every several decades. However, the processes driving the dynamics of these cycles are relatively unknown, which makes managing caribou herds for recreational and subsistence harvests difficult. It has been hypothesized that a combination of intrinsic and extrinsic factors shape these cycles, with density-dependence, predation, …
