A Phenological Analysis Of Páramo Vegetation Along An Altitudinal Gradient: The Influence Of Camelids On Andean Flora In The Páramo Of Chimborazo, Ecuador, Tessa Seifried

Independent Study Project (ISP) Collection

This study hopes to reveal the mechanisms behind camelid-plant interactions in the Chimborazo province of Ecuador, which is known for having a large population of domesticated alpacas (Vicugna pacos), along with wild vicuñas (Vicugna vicugna) that were reintroduced into the area 30 years ago. These camelid species, especially vicuñas, are understudied within Ecuador in regards to their effects on plant composition, diversity, and spatial phenology. To gain a better insight into this topic, three sites were chosen: a site inhabited by only vicuña, a site inhabited by only alpaca, and a site inhabited by both species. The vicuña site sat …

Beach Suitability For Nesting Olive Ridley Sea Turtles (Lepidochelys Olivacea), Playa Malena, Azuero Peninsula, Panama, Soleil Foy

Independent Study Project (ISP) Collection

Sea turtle species all over the world are facing continuous declines in their populations partly due to diminished viable nesting habitat. Understanding sea turtle nesting preferences and the suitability of beaches for reproductive success is necessary in order to sustain their populations and ensure their conservation. Olive ridley sea turtles (Lepidochelys olivacea) are one of the species experiencing this trend, especially in the Eastern Pacific. This study examined the beach suitability of a site known as Playa Malena in the Azuero Peninsula in Panama for Olive ridley nesting. This site was compared to the suitability of 7 other …

Rapid Quantitative Analysis Of Toxic Norditerpenoid Alkaloids In Larkspur (Delphinium Spp.) By Flow Injection - Electrospray Ionization – Mass Spectrometry, Dale R. Gardner, Stephen T. Lee, Daniel Cook

Poisonous Plant Research (PPR)

A rapid flow injection - electrospray ionization – mass spectrometry (FI-ESI-MS) method for the quantitative and qualitative analysis of norditerpenoid alkaloids in larkspur plants was developed. The FI-ESI-MS method was calibrated for alkaloid concentrations with larkspur plant samples against an existing Fourier transform infrared spectroscopy FTIR method. There was a strong correlation (r = 0.9926, r = 0.9891) between the FTIR and FI-ESI-MS methods. The relative standard deviation (RSD) for all measurements were ≤ 6.2 % except for the sample with the lowest concentration which was 19%. The sample throughput of the FI-ESI-MS method is much higher than the FTIR …

Assessing the body condition of wild animals is necessary to monitor the health of the population and is critical to defining a framework for conservation actions. Body condition indices (BCIs) are a non-invasive and relatively simple means to assess the health of individual animals, useful for addressing a wide variety of ecological, behavioral, and management questions. The Antillean manatee (Trichechus manatus manatus) is an endangered subspecies of the West Indian manatee, facing a wide variety of threats from mostly human-related origins. Our objective was to define specific BCIs for the subspecies that, coupled with additional health, genetic and …

Molecular Genetic Analysis Of Stygobiotic Shrimps Of The Genus Xiphocaridinella (Crustacea: Decapoda: Atyidae) Reveals A Connection Between Distant Caves In Central Abkhazia, Southwestern Caucasus, Ivan Marin, Ilya Turbanov

International Journal of Speleology

Based on the morpho-genetic study of stygobiotic shrimps from the genus Xiphocaridinella Sadowsky, 1930 (Crustacea: Decapoda: Atyidae), a hydrogeological connection of a number of distant caves in Central Abkhazia of the southwestern Caucasus is satisfied, which indicates the possibility of using biospeleological studies in some cases to identify karst hydrosystems together with traditional hydrogeological methods. Moreover, a new stygobiotic atyid shrimp from the genus Xiphocaridinella, X. kelasuri sp. n., is described based on morphology and analysis of mitochondrial cytochrome oxidase I DNA sequences from three distant caves. The new species is genetically divergent from relatives and phylogenetically related to …

Autoradiographic Localization Of [3h]-Nisoxetine Binding Sites In The Cns Of Male And Female Japanese Quail, Shannon E. Eaton, James R. Pauly, Deann M. Hopkins, Chana K. Akins

Pharmaceutical Sciences Faculty Publications

Background

In the central nervous system of mammals, transporters localized on the presynaptic nerve terminals regulate the reuptake of neurotransmitters. These transporters are selective for a specific neurotransmitter such as dopamine (DA) and norepinephrine (NE). Specifically in the synapse, the dopamine transporter (DAT) reuptakes DA and the norepinephrine transporter (NET) reuptakes NE. However previous research has found that avian species do not have a gene for DAT, and therefore, birds may be using the NET to clear both NE and DA from the synapse. The current study aimed to extend this finding by localizing NET expression in male and female …

Whole-Genome Sequencing To Investigate A Possible Genetic Basis Of Perosomus Elumbis In A Calf Resulting From A Consanguineous Mating, Alexa M. Barber, Alyssa Helms, Riley Thompson, Brian K. Whitlock, David J. Steffen, Jessica Lynn Petersen

Department of Animal Science: Faculty Publications

Perosomus elumbis (PE) is a lethal, congenital defect marked by aplasia of the lumbar and sacral spine and spinal cord. Contracture of the hind limbs is also commonly observed in affected individuals. PE has been reported in many domestic species, with numerous case reports in Holstein cattle in the past two decades (Jones, 1999; Karakaya et al., 2013; Agerholm et al., 2014). The etiology of PE remains unknown. In one instance, a stillborn Holstein calf with PE was found to be infected with Bovine Viral Diarrhea Virus (BVDV) (Karakaya et al., 2013), and thus, it is possible that PE may …

Novel Pilot Development Of A Closed-Loop Sustainable System Between Biogas Renewable Energy, Distilling, And Aquaculture By Vermiculture Of Stillage Wastes, Samuel C. Kessler

The Cardinal Edge

This study provides a mixed-methods approach in analyzing a potential closed-loop system between renewable biogas production from anaerobic digestion, vermiculture production, aquaculture production, and organic wastes with a particular focus on stillage wastes. Such system may hold significant promise for significantly reducing organic carbon and methane emissions from its components, and should be assessed for such. The 2021 IPCC report essentially identified methane reduction as the single fastest way to slow global warming (IPCC, 2021), making the study and implementation of methane-reducing systems and supportive policy for them critical. Knowledge gaps to implementing this system were qualitatively identified as disconnect …

Judgement Bias In Miniature Donkeys: Conditioning Factors And Personality Links, Maria Pinto, Francisco Javier Navas González, Camie Heleski, Amy Mclean

Animal and Food Sciences Faculty Publications

Expectation-related bias may configure individuals’ perception of their surrounding environment and of the elements present in it. This study aimed to determine the repercussions of environmental (weather elements) or subject-inherent factors (sex, age, or personality features) on judgment bias. A cognitive bias test was performed in eight Miniature jennies and four jacks. Test comprised habituation, training and testing phases during which subjects were trained on how to complete the test and scored based on their latency to approach an ambiguous stimulus. A questionnaire evaluating eleven personality features was parallelly completed by three caretakers, five operators and two care assistants to …

Harness Organoid Models For Virological Studies In Animals: A Cross-Species Perspective, Yongming Sang, Laura C. Miller, Rahul K. Nelli, Luis Gabriel Giménez-Lirola

Agricultural and Environmental Sciences Faculty Research

Animal models and cell culture in vitro are primarily used in virus and antiviral immune research. Whereas the limitation of these models to recapitulate the viral pathogenesis in humans has been made well aware, it is imperative to introduce more efficient systems to validate emerging viruses in both domestic and wild animals. Organoids ascribe to representative miniatures of organs (i.e., mini-organs), which are derived from three-dimensional culture of stem cells under respective differential conditions mimicking endogenous organogenetic niches. Organoids have broadened virological studies in the human context, particularly in recent uses for COVID19 research. This review examines the status and …

Kentucky Equestrians: Defining Socioeconomic Contexts For Extension Programming, Kimberly I. Tumlin, Karin Pekarchik, Steven Claas

Journal of Extension

Understanding relationships between demographic and economic factors and equestrian participation could improve horse program design. We implemented an online survey that characterized associations of participation in equine activities, socioeconomic factors, and economic factors with age. Seventy-five percent of respondents ride, and 34% are recreational, non-competitive participants. Respondents were mostly female, and many participate in the sport throughout life. Many respondents indicated they overspent on equestrian activities. Horse programs should incorporate information and activities that address issues unique to females, should develop skills required by amateur or recreational riders, and should incorporate information on financial wellness.

A Modular Open-Technology Device To Measure And Adjust Concentration Of Sperm Samples For Cryopreservation, Nikolas C. Zuchowicz

LSU Master's Theses

Repositories for aquatic germplasm can safeguard the genetic diversity of species of interest to aquaculture, research, and conservation. The development of such repositories is impeded by a lack of standardization both within laboratories and across the research community. Protocols for cryopreservation are often developed ad hoc and without close attention to variables, such as sperm concentration, that strongly affect the success and consistency of cryopreservation. The wide dissemination and use of specialized tools and devices can improve processing reliability, provide data logging, produce custom hardware to address unique problems, and save costs, time, and labor. The goal of the present …

Heat Stress And Reproduction In Beef Cattle, Reganne K. Briggs, Kerry A. Rood

All Current Publications

Reproduction could be considered the most important production trait on a cow-calf operation. Economic outputs are sustained when cattle rebreed and calve every year in a timely manner. However, when cattle are unable to rebreed efficiently, profits may decrease for producers. It is well known that heat stress can negatively impact reproduction in cattle (Jordan, 2003). The Intermountain West has been impacted by drought and increasing temperatures, both of which can impact reproduction rates in cattle. This fact sheet helps producers understand the consequences of heat stress on cattle reproduction and how they can manage reproduction during increasing temperatures.

Using Beet Pulp To Adapt Cattle To Finishing Diets Compared To Traditional Grain Adaptation With Alfalfa Hay, C. J. Schneider, Matt K. Luebbe, K. H. Jenkins, Stephanie A. Furman Furman, Galen E. Erickson, Terry J. Klopfenstein

Department of Animal Science: Faculty Publications

A study was conducted to compare grain adaptation programs using beet pulp (BP) to traditional grain adaptation with alfalfa hay (AH). Yearling crossbred steers (n = 232; BW = 326 ± 14.5 kg) were separated into 3 weight blocks, stratified by BW, and assigned randomly, within strata, to 18 feedlot pens, with 12 or 13 steers per pen. Treatments were imposed during grain adaptation (21 d) using 3 grain adaptation programs. Within each grain adaptation program, 4 step rations were fed for 3, 4, 7, and 7 d. Each program increased dry-rolled corn inclusion while roughage inclusion decreased. In the …

The naked mole‐rat (Heterocephalus glaber) has fascinated zoologists for at least half a century. It has also generated considerable biomedical interest not only because of its extraordinary longevity, but also because of unusual protective features (e.g. its tolerance of variable oxygen availability), which may be pertinent to several human disease states, including ischemia/reperfusion injury and neurodegeneration. A recent article entitled ‘Surprisingly long survival of premature conclusions about naked mole‐rat biology’ described 28 ‘myths’ which, those authors claimed, are a ‘perpetuation of beautiful, but falsified, hypotheses’ and impede our understanding of this enigmatic mammal. Here, we re‐examine each of …

Characterisation Of Early Positive Mcr‐1 Resistance Gene And Plasmidome In Escherichia Coli Pathogenic Strains Associated With Variable Phylogroups Under Colistin Selection, Guerrino Macori, Scott V. Nguyen, Ankita Naithani, Daniel Hurley, Li Bai, Farid El Garch, Frédérique Woehrlé, Christine Miossec, Benjamin Roques, Peadar O’Gaora, James L. Bono, Séamus Fanning

Roman L. Hruska U.S. Meat Animal Research Center: Reports

An antibiotic susceptibility monitoring programme was conducted from 2004 to 2010, re-sulting in a collection of 143 Escherichia coli cultured from bovine faecal samples (diarrhoea) and milk‐aliquots (mastitis). The isolates were subjected to whole‐genome sequencing and were distrib-uted in phylogroups A, B1, B2, C, D, E, and G with no correlation for particular genotypes with pathotypes. In fact, the population structure showed that the strains belonging to the different phy-logroups matched broadly to ST complexes; however, the isolates are randomly associated with the diseases, highlighting the necessity to investigate the virulence factors more accurately in order to identify the mechanisms …

Otoliths Of South-Western Australian Fish: A Photographic Catalogue, Chris Dowling, Kim Smith, Elaine Lek, Joshua Brown

Fisheries Research Reports

Due to the species-specific nature of otoliths and given they are often the only part of the fish preserved when fish die, otolith catalogues can be used in numerous applications, such as diet studies in fish eating animals, including pinnipeds, fish and sea birds; archaeological purposes such as reconstructing indigenous people’s diets from otoliths found in middens or evolutionary history of fish species by comparing fossilized otoliths. Given the unique mixture of subtropical and temperate fish, including many endemic species that occur off the southwest corner of WA having a catalogue for this area is extremely important for people working …

Scaup Depredation On Arkansas Baitfish And Sportfish Aquaculture, Stephen A. Clements, Brian S. Dorr, J. Brian Davis, Luke A. Roy, Carole R. Engle, Katie Hanson-Dorr, Anita M. Kelly

United States Department of Agriculture Wildlife Services: Staff Publications

Lesser scaup (Aythya affinis) and greater scaup (A. marila), hereafter scaup, consume a variety of aquatic invertebrates, plants, and occasionally small fish. Scaup have foraged on commercial aquaculture farms in the southern United States for decades. However, the types, abundance, and rate of fish exploitation by scaup on baitfish and sportfish farms are not well documented. Thus, information is needed to understand how fish and other foods influence scaup use of aquatic resources, and any potential economic effects of depredation of fish. From November–March in winters 2016–2017 and 2017–2018, we conducted 1,458 pond surveys to …

Black-Throated Gray Warbler In Knox County, Nebraska, Mark A. Brogie

Nebraska Bird Review

The Nebraska Ornithologists’ Union Records Committee (NOURC) considers Black-throated Gray Warbler (Setophaga nigrescens) to be Accidental in Nebraska (NOURC 2017). Silcock and Jorgensen (2020) list a total of seven accepted records with only two occurring in fall: an adult male at the Hyannis Cemetery, Grant Co., 01 Sep 2002 (Brogie 2003) and a female at Oliver Reservoir, Kimball Co., 07 Sep 2001 (Silcock 2001). The following documents the third Nebraska fall record for Black-throated Gray Warbler, the third record east of the Nebraska Panhandle, the first for northeast Nebraska, and the only NOURC accepted record (#2338) in the last decade.

A Brown-Capped Black-Capped Chickadee (Poecile Atricapillus) In Sarpy County, Nebraska, W. Ross Silcock, Phil Swanson

Nebraska Bird Review

Beginning 31 May 2021, Phil Swanson captured a series of videos and photos of an apparent family group of Black-capped Chickadees (BCCH). Five birds were seen together through 2 June, 2-4 through 6 June, and 2-3 through 9 June, during which all sightings included begging. Thereafter 1-2 birds per day were seen but without interactions between them. One of the family group had a brown cap (Figures 1, 2), and was presumably a juvenile based on its propensity for begging for food and partial replacement of its greater coverts (Pyle 1997). This condition has been described as “rare” (Sibley 2011), …

Summer Field Report, June-July 2021, W. Ross Silcock

Nebraska Bird Review

Last summer my opening sentences were: “Overall, this was a fairly routine summer although birders in Nebraska know that ‘routine’ still holds promise of a few happenings out of the ordinary. The summer season primarily examines new breeding records, range expansions, and changes in numbers, up or down.” This summer was also rather routine but had its share of startling events. Foremost among these were only the second colony breeding of American White Pelicans, involving 1200 on nests; two, possibly the same, male Evening Grosbeaks in the southeast; record late by about a month Townsend’s Solitaire; two Lincoln’s Sparrows together …

Diminishing Returns: Results Of Black Rail Surveys In Nebraska, Joel G. Jorgensen, Lauren Greenwalt, Nancy E. Drilling, Caleb Strand, Stephen J. Brenner

Nebraska Bird Review

The uncertain status of the Black Rail in Nebraska is problematic. Different authors have interpreted existing reports differently resulting in varying conclusions about the species’ status. The exercise of deciphering the limited details of existing reports and litigating their credibility is of little value. The Black Rail is now a threatened species and there is almost no published information on whether it occurs regularly in Nebraska. Furthermore, the species has not been searched for in any consistent form or systematic manner. Without information and understanding about the species’ occurrence, taking actions to benefit and protect this species will undoubtedly be …

Green Economics: Assessing The Feasibility Of A New England Green Crab (Carcinus Maenas) Fishery Through Fishermen Perspectives, William L. Walter

All Theses And Dissertations

The European green crab (Carcinus maenas) is a well-adapted invasive species that has flourished throughout coastal New England. Its arrival has caused numerous negative environmental and socioeconomic impacts, including the decline of the Maine soft shell clam (Mya arenaria) fishery. Increases in north Atlantic sea surface temperatures have simultaneously propelled the proliferation of C. maenas and caused northward shifts in the geographic ranges of commercially relevant species, including the American lobster (Homarus americanus). C. maenas represents an underutilized species that H. americanus and M. arenaria fishers can target to supplement any lost income if …

Evaluating Livestock Farmers Knowledge, Beliefs, And Management Of Arboviral Diseases In Kenya: A Multivariate Fractional Probit Approach, Paul Nyamweya Nyangau, Jonathan Makau Nzuma, Patrick Irungu, Menale Kassie

All Peer-Reviewed Publications

Globally, arthropod-borne virus (arbovirus) infections continue to pose substantial threats to public health and economic development, especially in developing countries. In Kenya, although arboviral diseases (ADs) are largely endemic, little is known about the factors influencing livestock farmers’ knowledge, beliefs, and management (KBM) of the three major ADs: Rift Valley fever (RVF), dengue fever and chikungunya fever. This study evaluates the drivers of livestock farmers’ KBM of ADs from a sample of 629 respondents selected using a three-stage sampling procedure in Kenya’s three hotspot counties of Baringo, Kwale, and Kilifi. A multivariate fractional probit model was used to assess the …
