Effect Of Multispecies Swards On The Fat Composition And Oxidative Stability Of Milk From Dairy Cows In Mid-Late Lactation, Samuel Rapisarda, Kate M. Mccarthy, Tommy M. Boland, Helen Sheridan, Frank J. Monahan, Finbar J. Mulligan, Graham O'Neill, Nissreen Abu-Ghannam

Articles

Multispecies swards have been recognized as more sustainable than traditional ryegrass systems, in addition to providing a range of phytochemicals to the ruminant diet. In this regard, polyphenols may be linked to higher levels of bioactive fatty acids in milk and enhanced nutraceutical properties in dairy products. This study compares the fat composition and oxidative stability of milk produced by cows fed on multispecies swards (MULTI) with milk from two conventional swards [a perennial ryegrass monoculture (PRG) and a mixture of perennial ryegrass and white clover (PRG + WC)] during the Irish summer. Milk from cows fed on MULTI had …

Lake Powell Fish Sampling: Glen Canyon Dam Forebay Area, 2022 And 2023, Phaedra Budy, Casey Pennock

Browse all Datasets

Native fishes face imperilment due to habitat loss and fragmentation, megadrought, invasive species, and synergies amongst threats. These threats coalesce at Glen Canyon Dam (GCD), which impounds the Colorado River to create Lake Powell, a reservoir inhabited by a suite of nonnative fishes. Water level in Lake Powell has declined precipitously due to water overallocation and megadrought, increasing the risk of nonnative fish entrainment through the dam, as the penstocks draw water from the epilimnion. Our goal was to characterize the distribution and abundance of nonnative fishes in the vicinity of GCD and identify environmental conditions that may increase entrainment. …

Sewing With Fur, Cory Farnsworth

All Current Publications

Today, trapping is one of the most regulated activities worldwide and is a useful tool in managing excess populations of furbearers and struggling populations of prey animals. Fur is slowly regaining popularity as people recognize it as more ethical, humane, economical, and renewable, but the ability to use fur is becoming a lost art. It is part of our heritage as a people and connects us with the land. Learning to sew fur projects can be fun and, in some cases, quite profitable, as fur sewn into an article will sell far above the price of the pelt itself. If …

Exploring Single Cell Microbial Protein As A Sustainable Fishmeal Alternative In Yellowtail Kingfish (Seriola Lalandi) Diets: Impacts On Health And Gut Microbiome, Luke Pilmer, Lindsey Woolley, Alan Lymbery, Chinh Dam, Abigail Elizur, Md Javed Foysal, Gavin Partridge

Fisheries Research Articles

Background

With the global expansion of aquaculture and the increasing demand for fish meal, identifying appropriate and sustainable alternative protein sources for aquafeeds has become essential. Single-cell protein (SCP), derived from methanotrophic bacteria, presents a promising alternative by converting methane into protein, potentially addressing both the need for alternative protein sources and reducing industrial greenhouse gas emissions. This study aimed to evaluate the effects of different levels of SCP inclusion (0%, 25%, 50%, and 75% fish meal replacement) on the health, gene expression, and gut microbiome of yellowtail kingfish (YTK, Seriola lalandi) following a 35-day growth trial.

An Approach To Estimate Angling Effort, Catch, And Harvest Of Burbot Lota Lota, Collin J. Mitchell

Biology Graduate Theses

Once commonly thought of as a nuisance, Burbot Lota lota are now being frequently targeted by anglers in Minnesota. However, the amount of angling effort directed at Burbot, the distribution of effort, catch, and harvest are unknown. Historically, creel surveys have been used to estimate angling effort, catch, and harvest. Additionally, digital cameras have been used independently and supplementally to estimate angling effort, catch, and harvest. In this study, we estimate angling effort, catch, and harvest of Burbot using creel survey techniques and motion-activated digital cameras on Bad Medicine Lake, Minnesota, while also investigating and exploring the limitations of these …

Long-Term Agricultural Management Reduces Abundance And Alters Community Structure Of Ground Beetles (Coleoptera: Carabidae), Cynthia M. Fiser, Nathan L. Haan, Douglas A. Landis

Entomology Faculty Publications

Carabid beetles (Coleoptera: Carabidae) are beneficial predators and bioindicators of ground-dwelling arthropod diversity in agricultural landscapes. We studied changes in community composition, activity density, and diversity of carabids in a long-term agroecosystem study spanning 30 years in the US Midwest. We contrasted carabid community metrics measured by pitfall trap sampling in two conservation-oriented treatments in a corn-soybean-wheat rotation. One treatment uses conventional practices but with reduced agrochemical inputs (Reduced Input), while the other has no synthetic inputs (Biologically Based). Since a 1994–95 study on the same site, in 2019 overall carabid activity density had declined a minimum of 58–76 % …

Marine Protected Species Identification Guide 2025, Department Of Primary Industries And Regional Development, Western Australia

Fisheries Occasional Publications

The Western Australian aquatic environment is home to a number of species that are protected under international agreements and national or state legislation. Many of these species occur in areas where fishing takes place, sometimes resulting in interactions between fishers and protected species. An interaction is considered to be any physical contact between a person, fishing vessel or fishing gear and a protected species, including captures, entanglements and collisions.

This guide has been developed to help you identify some common marine protected species in Western Australia that you may encounter while fishing.

It has been divided into 5 sections:

Coverage Matters: Identifying And Mitigating Sampling Frame Issues In Recreational Fishing Surveys, Steve Taylor, Annica De Groote, Kieran Hyder, Jon Volstad, B W. Hartill, J Foster, R Andrews, Karina L. Ryan

Fisheries Research Articles

Surveys play an integral part in monitoring and maintaining sustainable recreational fisheries. For any probabilistic survey, the selection of a sampling frame (e.g., list of individuals or fishers) is an important decision because it influences the ability to provide unbiased estimates of recreational catch and effort. Undercoverage occurs when units of the target population (i.e., the population of interest) are missing from the frame population. This error can undermine the reliability of research advice generated from survey estimates. In this review, we: (i) define six sampling frame configurations that are commonly applied in probabilistic recreational fishing surveys; (ii) synthesise how …

School of Integrative Biological & Chemical Sciences Faculty Publications

1. Understanding migratory connectivity, or the linkage of populations between seasons, is critical for effective conservation and management of migratory wildlife. A growing number of tools are available for understanding where migratory individuals and populations occur throughout the annual cycle. Integration of the diverse measures of migratory movements can help elucidate migratory connectivity patterns with methodology that accounts for differences in sampling design, directionality, effort, precision and bias inherent to each data type.
2. The R package MigConnectivity was developed to estimate population-specific connectivity and the range-wide strength of those connections. New functions allow users to integrate intrinsic markers, tracking and long-distance …

Evaluating The Performance Of Broccoli (Brassica Oleracea Var. Italica) In The Sandponics System Using Brackish Water With Biochar And Compost, Gabriel Oyebode

Theses and Dissertations

Some of the most pronounced effects of climate change on agricultural output include the depletion of freshwater resources and heightened salinization of arable land, especially in arid and semi-arid regions, adversely affecting crop yields. Many economic vegetable crops including members of the brassica family are sensitive to salt-stress. The use of organic soil amendments such as biochar and compost as complimentary nutrient sources in the sandponics system can improve the performance of crops. The study aimed to evaluate the effect of organic amendment on the growth performance and yield of broccoli and Nile tilapia (Oreochromis niloticus) under brackish …

Determining The Physiological And Behavioral Tolerance To Hypoxia In Two Species Of Rockfish (Sebastes Spp.), Makenna Chan

Theses

In the eastern North Pacific, the oxygen minimum zone naturally shoals seasonally and impacts demersal fish habitat along the continental margins and on offshore seamounts. This hypoxic layer has been shoaling in recent decades, likely affecting the habitat and distribution of commercially-important fish species such as rockfishes (genus Sebastes). Respirometry and shuttle box behavioral experiments were used to determine the hypoxia sensitivities of two rockfish species with contrasting movement patterns and habitat use: cowcod (Sebastes levis) and bocaccio (Sebastes paucispinis). Although both species inhabit similar deep-water, rocky-reef habitat, they have different lifestyles, in which cowcod …

Karbala International Journal of Modern Science

The viral disease affects the whiteleg shrimp (Litopenaeus vannamei) and causes losses. Immunostimulants are recognized as a more environmentally friendly approach to disease management and antimicrobial properties of aquatic organisms. Watercress (Nasturtium officinale) is an aquatic plant species that contains antioxidant properties that can protect the organism from disease and boost the immune system. Shrimp rely heavily on innate immunity to combat infectious agents due to their absence of adaptive immunity. Peroxinectin and scavenger receptor class B (SRB) play essential roles in the shrimp defense system. This research employs a bioinformatic to assess the immunostimulatory potential …

The Economics And Productivity Of Us Cow-Calf Production, Richard Nehring, Hannah Shear, Kelvin L. Leibold, Andrew Swanson

Journal of Applied Farm Economics

We explore US beef cow-calf production in 2018 and estimate net returns, returns to scale, and technical efficiency associated with backgrounding versus nonbackgrounding by size and production system. We determine the relative profitability of cow-calf operations by type, region, and size. Results, using both stochastic production frontier analysis and data envelopment analysis, indicate that larger operations tend to be more scale and technically efficient than smaller operations. While larger operations may be more scale and technically efficient and have lower variable costs per cow, off-farm income helps smaller operations become competitive. The availability of detailed cost of production information in …

Halogeton And Greasewood Poisoning In Cattle And Sheep In Utah, E. Jane Kelly, Stephen T. Lee, Ammon Brown, Daniel Cook

Poisonous Plant Research (PPR)

Halogeton (Halogeton glomeratus) is a fast-growing annual plant while greasewood (Sarcobatus vermiculatus) is a perennial shrub of the Western States. Oxalates are the toxic principle in halogeton and greasewood. Most losses occur when hungry animals are allowed to graze in heavy stands of halogeton and greasewood. Halogeton and greasewood are always dangerous and become more toxic as the growing season progresses. Here we report on two clinical cases of halogeton and greasewood poisoning in cattle and sheep. Histologically, oxalate crystals were observed in the kidneys of the cow and sheep consistent with oxalate poisoning. Oxalate was …

ʽAmqa: Faunal Remains From The Late Fatimid–Early Crusader Periods, Nimrod Marom

Qadum: Journal of Excavation Reports from Israel

This report analyzes faunal remains found in a building complex at ‘Amqa, primarily from the late Fatimid–early Crusader periods (eleventh–twelfth centuries CE). The assemblage consists mainly of cattle, sheep and goats, with a smaller number of camel, wild boar, equid, chicken and tortoise remains. Cattle bones, particularly from young individuals, are most prevalent, suggesting a focus on cattle rearing. Butchery marks indicate the use of tools for carcass processing, and bone fragmentation patterns suggest both intentional breakage and natural weathering. Comparisons with other sites from the same period highlight the unique predominance of cattle in ‘Amqa, possibly due to the …

The Eastern Oyster Behavioral Response To Low Salinity And Hypoxia In Controlled And Natural Settings, Siyah Yongue

LSU Master's Theses

Oyster aquaculture is expanding in the northern Gulf of Mexico, but climate change may challenge the sustainability of this industry. Projected increases in the frequency and intensity of low salinity and low dissolved oxygen (DO) periods could impact the behavior, metabolism, growth, and survival of oysters. Characterizing how oyster behavior links to environmental stressors could help better identify thresholds in their tolerance and inform predictive tools for aquaculture professionals. In this research, the effect of separate and concomitant exposures to low salinity and DO on the behavioral response of oysters was examined in the lab. The impact of other environmental …

Species Differences In The Biotransformation Of Aflatoxin B1: Primary Determinants Of Relative Carcinogenic Potency In Different Animal Species, David L. Eaton, David E. Williams, Roger A. Coulombe

Animal, Dairy, and Veterinary Science Faculty Publications

It has been known since the early days of the discovery of aflatoxin B1 (AFB1) that there were large species differences in susceptibility to AFB1. It was also evident early on that AFB1 itself was not toxic but required bioactivation to a reactive form. Over the past 60 years there have been thousands of studies to delineate the role of ~10 specific biotransformation pathways of AFB1, both phase I (oxidation, reduction) and phase II (hydrolysis, conjugation, secondary oxidations, and reductions of phase I metabolites). This review provides a historical context and substantive analysis of each of these pathways as contributors …

Key Virulence Factors Responsible For Differences In Pathogenicity Between Clinically Proven Live-Attenuated Japanese Encephalitis Vaccine Sa14-14-2 And Its Pre-Attenuated Highly Virulent Parent Sa14, Byung-Hak Song, Sang-Im Yun, Joseph L. Goldhardt, Jiyoun Kim, Young-Min Lee

Animal, Dairy, and Veterinary Science Student Research

Japanese encephalitis virus (JEV), a neuroinvasive and neurovirulent orthoflavivirus, can be prevented in humans with the SA₁₄-14-2 vaccine, a live-attenuated version derived from the wild-type SA₁₄ strain. To determine the viral factors responsible for the differences in pathogenicity between SA₁₄ and SA₁₄-14-2, we initially established a reverse genetics system that includes a pair of full-length infectious cDNAs for both strains. Using this cDNA pair, we then systematically exchanged genomic regions between SA14 and SA₁₄-14-2 to generate 20 chimeric viruses and evaluated their replication capability in cell culture and their pathogenic potential in …

Monitoring And Assessment Of Population, Reproductive, And Health Effects In Colonial Waterbirds Breeding At Contaminated Great Lakes Sites In Michigan, Keith A. Grasman, Mandy Annis, Carly Eakin, Jeremy Moore, Lisa L. Williams

University Faculty Publications and Creative Works

Immunological, reproductive, and population endpoints were assessed in fish-eating birds during 2010–2019 in the Saginaw River and Bay and River Raisin Areas of Concern (AOCs) and Grand Traverse Bay, which are ecosystems historically contaminated with polychlorinated biphenyls, dibenzo-p-dioxins, and dibenzofurans. Reference sites were in the lower St. Marys River (herring gulls and Caspian terns), eastern Lake Superior (terns), and eastern Lake Huron (black-crowned night herons). Relative risk ratios for embryonic nonviability (from both infertility and mortality) in gull embryos were 2–3-fold higher than the reference site in both AOCs and Grand Traverse Bay. Twelve of 13 deformed embryos and chicks …

The Manipulation Of Odor Availability Of Training Aids Used In Detection Canine Training, Katylynn B. Sloan, Michele N. Maughan, Caitlin E. Sharpes, Robin R. Greubel, Shawna F. Gallegos, Aleksandr E. Miklos, Lindsay D. Waldrop

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Detection canines can identify numerous substances for which they have been trained. Historically, and a point of ongoing contention, detection canine threshold (i.e., sensitivity or limit of detection) training has primarily focused on changing the weight of the training aid substance used. There has been minimal focus on other principles, such as surface area, confinement, and temperature, which can be manipulated to affect odor availability. That said, trainers have been manipulating odor availability for years without necessarily understanding the governing scientific principles. The aim of this review is to highlight the principles that control odor availability of a substance and …
