A Subspecies-Level Database Of Amazonian Bird Distributions, With Inferences On Suture Zones And Conservation, Marco Antonio Rego
A Subspecies-Level Database Of Amazonian Bird Distributions, With Inferences On Suture Zones And Conservation, Marco Antonio Rego
LSU Doctoral Dissertations
Amazonia has the largest and most biodiverse tropical forest on the planet. However, the distributions of its species are still poorly understood, even for well-studied vertebrates such as birds. Available distribution maps for Amazonian birds often lack accuracy in delimiting the area where species occur. Existing distributional information for Amazonian birds is often limited to species-level level taxonomy, even though many Amazonian bird subspecies represent biological species. Here, I investigate the geographic distributions of 4,148 bird taxa (species and subspecies) using museum scientific specimens as the primary source of data. To build the data base I use more than 600,000 …

Worldwide Distribution Of Cave-Dwelling Chelodesmidae (Diplopoda, Polydesmida), Rodrigo Salvador Bouzan, Jackson C. Means, Kaloyan Ivanov, Rodrigo L. Ferreira, Antonio Domingos Brescovit, Luiz Felipe Moretti Iniesta
International Journal of Speleology
Chelodesmidae is one of the most species rich families within the Myriapoda. However, little is known regarding their association with caves. We provide a list of all Chelodesmidae taxa reported from caves, map their worldwide distribution, and discuss the troglomorphic features of the group. A total of 25 species and subspecies from 20 genera and 2 subfamilies have been recorded from 59 caves and cave systems in 11 countries. These numbers represent a surprisingly modest proportion (~3%) of the approximately 800 described species in the family. Records of cave-dwelling chelodesmids appear to be geographically biased with most taxa reported from …
Insect Availability And Parental Care Behavior In A Common Bird, Cole Bourque
Insect Availability And Parental Care Behavior In A Common Bird, Cole Bourque
Symposium of Student Scholars
Populations of aerially insectivorous birds are declining throughout North America. Urbanization may indirectly contribute to this decline through its negative effects on populations of insects, an important food source in insectivores' diets, where low insect availability may be especially challenging for birds during breeding. How fluctuations in insect populations impact various species at higher trophic levels is an important area of current study for future conservation biology. Here, we examine whether nestling provisioning, brooding and guarding behaviors in a breeding bird—the European starling (Sturnus vulgaris)—may be altered depending on the relative insect availability in the environment. We found …
Preliminary Analysis Of The Effects Of Non-Target Supplemental Feeding On Camera Trap Captures Of Small Mammals In Central Georgia, Raena Mccown, Travis Cunningham, Alfred J. Mead
Preliminary Analysis Of The Effects Of Non-Target Supplemental Feeding On Camera Trap Captures Of Small Mammals In Central Georgia, Raena Mccown, Travis Cunningham, Alfred J. Mead
Georgia Journal of Science
Supplemental bird feeding is a widespread hobby throughout western culture. Although it brings joy to many people, bird feeding has been shown to have potentially negative effects on local bird populations and small mammalian species. To study the differences in local occurrence of native small mammalian species around bird feeders and in more distant settings, six camera traps were placed in a rural residential area in Putnam County, Georgia. Three cameras were placed facing bird feeders and three placed a minimum of 60 m away from the feeders. Species presence was recorded three days a week from 12:00 am Monday …

The reservoir for zoonotic o’nyong-nyong virus (ONNV) has remained unknown since this virus was first recognized in Uganda in 1959. Building on existing evidence for mosquito bloodfeeding on various frugivorous bat species in Uganda, and seroprevalence for arboviruses among bats in Uganda, we sought to assess if serum samples collected from bats in Uganda demonstrated evidence of exposure to ONNV or the closely related zoonotic chikungunya virus (CHIKV). In total, 652 serum samples collected from six bat species were tested by plaque reduction neutralization test (PRNT) for neutralizing antibodies against ONNV and CHIKV. Forty out of 303 (13.2%) Egyptian rousettes …

Crustacean Assemblage Structure Over The Charlie-Gibbs Fracture Zone Of The Mid-Atlantic Ridge Collected During The 2009 Henry B. Bigelow Expedition, Kathryn Medina
All HCAS Student Capstones, Theses, and Dissertations
The Charlie Gibbs Fracture Zone (CGFZ) consists of two nearly parallel fracture transform faults that intersect the Mid-Atlantic Ridge (MAR) axis. This area has high primary productivity and biomass levels due to the topography and water. A predominant hydrographic feature of the MAR is the Sub-Polar Front (SPF) which runs along the southern edge of the CGFZ and is known as a biogeographical boundary for multiple species. As part of The Census of Marine Life project Patterns and Processes of the Ecosystem of the northern Mid-Atlantic (MAR-ECO), this study analyzed the abundance and distribution patterns of the CGFZ crustacean community …
Aquaculture In Africa: Aquatic Animal Welfare, Impact On The Environment And The Sustainability Of The Sector, Mwenda M. Mbaka, Janice H. Cox, Stephen Ronan
Aquaculture In Africa: Aquatic Animal Welfare, Impact On The Environment And The Sustainability Of The Sector, Mwenda M. Mbaka, Janice H. Cox, Stephen Ronan
Aquaculture
The African aquaculture sector recorded the fastest growth in the world between 2006-2018, averaging 10% or more, and is expected to partially fill the growing fish supply-demand gap up to 2063. In 2018, there were about 1.2 million aquafarmers across the continent, an increase from 920 thousand in 2014. According to the African Development Bank, expansion of aquaculture in Africa is hampered by "the overwhelming predominance of tilapia farming, which relies heavily on the production of fingerlings from a limited number of genetically improved strains that are resistant to the many diseases affecting this species, and on the production of …
Developing Novel Remote Camera Approaches To Assess And Monitor The Population Status Of Australian Sea Lions, Mathew Hourston, Daniela Waltrick, Stuart Blight, Ainslie Denham, Alex Hesp, Steve Taylor
Developing Novel Remote Camera Approaches To Assess And Monitor The Population Status Of Australian Sea Lions, Mathew Hourston, Daniela Waltrick, Stuart Blight, Ainslie Denham, Alex Hesp, Steve Taylor
Fisheries Research Reports
This project trialled the use of remote cameras to monitor the relative abundance of Australian sea lions (ASLs, Neophoca cinerea) at three Western Australian (WA) breeding colonies. The research was undertaken by the Department of Primary Industries and Regional Development (DPIRD) to assess whether the analysis of camera footage could be used to estimate ASL relative abundance, providing an alternative to the traditional “boots on the ground” approach (hereon in “BoG”) of visiting colonies to count animals. This report outlines the strengths and limitations of this novel approach rather than providing an update on the population status of ASLs. …

Occurrence Of Bat Species At Water Sources In Two Urban Parks In Nashville, Tennessee, Maya Kiev, Austin Farris, Evan Mason
Science University Research Symposium (SURS)
Animal behavioral patterns can shift due to anthropogenic factors related to pollution, human impact on flora/fauna, and changes in local water sources. While sound pollution can impact the occurrence of bats in urban areas, other factors could also influence bat behavior. This study examines bat occurrence near a water source at two urban parks in Nashville, Tennessee: one is in a highly trafficked area while the other is secluded and bordered by a suburban neighborhood. Both parks have small ponds, numerous trees, and open green spaces. Echo Meter Touch 2 devices were used to capture bat echolocation data at each …
Environmental Influences On The Growth Of Inland Cisco Populations In Three Minnesota Sentinel Lakes, Edward Carlson
Environmental Influences On The Growth Of Inland Cisco Populations In Three Minnesota Sentinel Lakes, Edward Carlson
Biology Graduate Theses
Cisco Coregonus artedi are a pelagic cold-water fish that are widely distributed throughout many inland lakes across the northern Midwest and play an important role as forage for large piscivores. Inland Cisco populations have been observed to vary in their overall size and recruitment potential based on the system in which they are found. Cisco are sensitive to oxythermal stress and with climate change, land use, and invasive species effects becoming more prevalent in Minnesota, aspects of lake ecosystems are changing, ultimately making Cisco more susceptible to these stressors. To investigate how different factors were affecting the population dynamics of …

Remembering Clem Klaphake, Don Paseka
Nebraska Bird Review
Clement (Clem) Klaphake passed away on December 30, 2022, from complications of Parkinson’s disease, which he struggled with for several years. He was born in Melrose, Minnesota, in 1943 and grew up working on his parents’ dairy farm, which included the usual menagerie of other farm animals typical of that time. Perhaps it was the routine of milking twice a day, seven days a week, or the impressive scar on his leg from a boar tusk, but Clem was destined to leave the farm and become a life-long educator. ... After getting his degree in 1971, Clem was hired to …
Comparison Of Kanamycin-Resistant Bacteria In Earthworm Digestive Tracts And Soil From Compost Bins, Samantha Dooyema, Martin Dolan, Abigal Morse
Comparison Of Kanamycin-Resistant Bacteria In Earthworm Digestive Tracts And Soil From Compost Bins, Samantha Dooyema, Martin Dolan, Abigal Morse
Science University Research Symposium (SURS)
Antibiotic-resistant bacteria are becoming more prevalent in soil as humans have increased impacts on the environment. Previous research proposed that earthworms could affect bacteria distribution as soil is ingested and filtered through their bodies. This research aims to see if kanamycin-resistance bacteria is the same in earthworm digestive tracts as in the soil the earthworms inhabit. We expect that the gut contents and soil will vary in the occurrence of kanamycin-resistant bacteria. Earthworms and composted soil samples were collected from compost bins at a residential home in Nashville, Tennessee. Digestive tracts were dissected from the earthworms and homogenized. Kanamycin-resistant bacteria …

Pilot Testing A Survey To Evaluate Horse Owner And Trainer Perceptions Of The Importance And Ideality Of Equine Hoof Balance, Katherine Gilmore
Animal Science Undergraduate Honors Theses
Balance plays an integral role in the healthy equine hoof, yet there is a significant deficiency of research investigating horse owner and trainer knowledge of hoof balance. This study aimed to pilot test an online survey instrument evaluating horse owner and trainer perceptions of proper hoof care and balance. The survey instrument sought to collect demographic information of horse owners and trainers, determine horse owners’ and trainers’ abilities to identify ideally balanced equine forehooves, and assess horse owner and trainer knowledge of best hoof trimming and shoeing practices. Ninety-one horse owners and trainers with facilities that were within a 150-mile …
An Evaluation Of Bovine Reproductive Function From The Microrna Expression In The Female To Performance Testing In The Male, Erin Amiss
All Theses
Reproductive function is crucial to the success of a beef or dairy herd. Both the female and male play significant roles in the outcome of bovine reproduction. The bull contributes to reproductive success in many ways, such as genetics. The initial role that the bull has in reproductive success is fertilization, whether natural or by artificial insemination. One method of assessing bull performance are central bull test stations, which are traditionally administered by a university, extension center, or are privately owned. Central bull tests assess the performance of bulls from various management systems, breeds, and ages. Some measurements taken during …

Impact Of Housing And Management On Production, Behavior, And Welfare Of Dairy Cows In Automatic Milking Systems, Lindsey Eve Davis
All Theses
The overall objective of this research was to determine the impact of Automatic Milking System (AMS) housing and management practices on cow production, behavior, and welfare of Holstein dairy cows. The first objective was to identify factors at the farm and cow level associated with lameness on AMS farms through decision tree analysis to allocate probabilities to each input. Results indicated this novel multifactorial approach of data analysis enabled us to highlight critical points that can be focused on to lessen cow-level complications or enhance farm-level housing and management practices to reduce the incidence and severity of lameness in AMS …
Patterns Of Occurrence Of The Black Basses In The Upper Savannah River Tributaries Of Georgia And South Carolina With Emphasis On Bartram’S Bass Micropterus Sp. Cf. Coosae, Caroline Cox
All Theses
Aquatic ecosystems are among the most threatened in the world due to anthropogenic alterations to the natural landscape and native biotas. Identifying the local and landscape-level environmental factors that influence the occurrence of endemic species can help protect aquatic ecosystems by facilitating predictions of where hybridization or replacement with generalist species may occur across the landscape. The need for such predictions is pronounced for black bass species in the southeastern United States. Bartram’s Bass (Micropterus sp. cf. coosae) is a provisional species of conservation concern. Allelic frequencies of Bartram’s Bass in Savannah River reservoirs and tributaries have been …

The human digestive tract is colonized by trillions of bacterial cells that play important roles in human health and diseases. It is well known that dietary habits are associated with human microbiota enterotypes. However, the factors that determine the enterotype still remain elusive. In this study, it was first examined, via in vitro batch fermentation, how different carbohydrates affect the Bacteroides and Prevotella enterotypes. Among the 11 substrates (fructo-, galacto-, xylo-, manno-, and isomalto-oligosaccharides [IMO] and lactulose, raffinose, starch, inulin [INU], mannitol, and xylitol) tested, IMO, INU, and starch were found to sustain the growth of Prevotella through batch fermentation. …

Identification Of Possible Vectors For Histomoniasis In Turkeys On Commercial Farms In Arkansas And Oklahoma, Treva Dillon
Graduate Theses and Dissertations
Histomonas meleagridis, is a parasitic protozoan, commonly found in the gallinaceous species of birds and is the causative agent of Blackhead disease. The cecal worm, known as Heteraskis gallinarum, acts as a vector in the spread of H. meleagridis in gallinaceous birds. H. meleagridis develops inside the cecal worm and in its eggs which allows H. meleagridis a method to survive in the environment. Blackhead disease causes high mortality rates in both chickens and turkeys; however, turkeys are noted to have a higher mortality rate compared to chickens. Molecular diagnostic testing such as PCR has been developed by creating primers …
