A Case Of Milkweed Poisoning In Cattle In Colorado, Raye Walck, Brett Webb, Steve Ensley, Daniel Cook

Poisonous Plant Research (PPR)

Milkweeds, Asclepias spp., are herbaceous perennials of the Apocyanaceae family. Milkweeds contain several cardiac glycosides, cardenolides, that are toxic. Clinical signs associated with milkweed toxicity are generalized weakness, difficulty in breathing, rapid weak pulse, bloating, violent spasms, paralysis, and death. Here we report a clinical case of milkweed toxicity in cattle due to contaminated hay. Clinical signs observed in the poisoned animals were consistent with cardenolide toxicity. Milkweed was detected in the rumen contents of the poisoned cow using DNA metabarcoding. In summary, multiple lines of corroborative evidence were used to make the diagnoses of milkweed poisoning in this case.

New Drainage Records And Revised Ranges For Sympatric Pirate Perch Species In Alabama, Florida, And Georgia, Tyler Muller, Bryson Hilburn, Lily Hughes

Southeastern Fishes Council Proceedings

We report updated ranges for four sympatric species of Pirate Perches following a recent taxonomic revision of Aphredoderus. Using observations from recent sampling by the North Carolina State Museum of Natural Sciences and reidentifying cataloged specimens from the Georgia Museum of Natural History and Auburn University Museum collections, we were able to refine the distributions of four species throughout a complicated sympatric zone spanning coastal plain drainages in Alabama, Florida, and Georgia. We find that A. gibbosus is present in low numbers in the Flint, Escambia, Choctawhatchee, and Chattahoochee basins. These additional records nearly link the previously reported disjunct …

Background The Syrian hamster (Mesocricetus auratus) has shown promise as a human diseases model, recapitulating features of different human diseases including COVID-19. However, the landscape of its genome and transcriptome has not been systematically dissected, restricting its potential applications.

Results Here we provide a complete analysis of the genome and transcriptome of the Syrian hamster and found that its lineage diverged from that of the Chinese hamster (Cricetulus griseus) around 29.4 million years ago. 21,387 protein-coding genes were identified, with 90.03% of the 2.56G base pair sequence being anchored to 22 chromosomes. Further comparison of the …

The Design, Construction, And Testing Of Mrna Vaccine Against Equine Herpes Virus, Bhawana Devkota

LSU Master's Theses

Equine Herpesvirus-1 (EHV 1) is a worldwide significant pathogen that causes respiratory illness, abortion, and neurological disorders in equine. Current vaccines, including live attenuated, inactivated, and subunit platforms, do not prevent viral latency, mucosal shedding, or cross-strain immunity, requiring alternative approaches. To address these gaps, this project explores the design, synthesis, and in vitro testing of an mRNA vaccine targeting immunogenic EHV 1 glycoprotein (gB, gC, gD, gG, and gM). Epitopes were computationally predicted using the Immune Epitope Database (IEDB), codon-optimized for Bos taurus, and cloned into pUCIDT vectors using SP6/T7 promoters. In vitro transcription (IVT) used nucleotide modifications …

Two Unique Cases Of Ponderosa Pine Needle-Induced Abortions, Kevin D. Welch, Megan A. Dietz, Steven E. Edmonds, Dale R. Gardener, Daniel Cook

Poisonous Plant Research (PPR)

Ponderosa pine (Pinus ponderosa) needles can induce abortions in cows when consumed during the last trimester of pregnancy. Traditionally pine needle-induced abortions occur in areas where cattle are forced into a stand of ponderosa pine trees to seek shelter and feed during a winter storm that is either very cold, has heavy snow or high winds. However, here we report two incidences of pine needle-induced abortions in cattle that were unique. In one case, there was no weather-related event that forced the cattle into the stand of pine trees, rather the cattle went into the pine trees seeking …

Nebraska Beef Cow Breeding Herd As Capital Stock, Richard Perrin, Margarida Noelia De Aguiar Cunha Souza, Lilyan E. Fulginiti

Cornhusker Economics

Throughout her lifetime, the capital stock value of a cow first rises as the size/quality of calves increase, then declines because there are fewer calves expected over her remaining lifetime. The value later in life begins to rise in anticipation of culling value.

We estimate the age distribution of the Nebraska cow herd every year, then we estimate the capital value of each cohort. Adding these values across ages and adjusting to 2015 prices, we obtain the series of capital values, measured in terms of 2015 dollars.

In addition, we calculate the value of the annual flow of services provided …

Predicting The Suitable Habitats Of Alosimus Marginicollis (Haag-Rutenberg, 1880) (Coleoptera: Meloidae) And Evaluating Its Potential Distribution In Relation To Geographical And Climatic Barriers, Muhammed Ari̇f Demi̇r, Mahmut Kabalak

Turkish Journal of Zoology

The main objective of this study was to predict the ecological requirements of Alosimus marginicollis (Haag-Rutenberg, 1880), for which limited ecological information is available, and to predict possible suitable habitats under current conditions and different future scenarios. An ensemble model-based approach, combining multiple algorithms (GAM, GLM, MARS, MaxEnt), was used to predict suitable habitats for this species using bioclimatic, topographic and land cover variables. The models indicated that the elevation variable among the topography variables, BIO15 (precipitation seasonality) and BIO4 (temperature seasonality) among the bioclimatic variables, and the cropland variable (cultivated and managed vegetation cover) among the land cover variables …

Did Raja Asterias Ever Occur In The Sea Of Marmara Or Were Previous Records Just Cases Of Misidentified Raja Clavata?, Hakan Kabasakal, Uğur Uzer, Fi̇rdes Saadet Karakulak

Turkish Journal of Zoology

The current inventories of elasmobranchs in the Sea of Marmara have some taxonomic problems that need to be solved. One problematic species in the elasmobranch fauna of the region is Raja clavata Linnaeus, 1758, and atypically coloured specimens of this skate species may have been misidentified in the past as congeners or closely related species. The present results show that R. asterias may be a misidentified species of the family Rajidae due to confusion with the atypically coloured R. clavata. As taxonomy is central to the integration of data sources in the context of biodiversity research and management of any …

Integrative Taxonomy Reveals The Existence Of A New Species Of Fat-Tailed Scorpions, Androctonus (Buthidae), In Iran, Hossein Barahoei, Omid Mirshamsi, Masoumeh Amiri, Asma Moeinadini, Ehsan Rakhshani

Turkish Journal of Zoology

Two species of Androctonus have been reported to date from Iran: Androctonus crassicauda (Olivier, 1807) and A. sistanus Barahoei and Mirshamsi, 2022, which is distributed only in the southeast of Iran. Investigating and identifying the distribution range of dangerous species is critically important for scorpion management. A total of 105 specimens of Androctonus were collected from representative locations in Esfahan, Yazd, Kerman, Hormozgan, Hamadan, and Khuzestan provinces. These samples were studied morphologically, morphometrically, molecularly (COI gene sequencing), and through species distribution modeling (SDM) using the MaxEnt model. Four Androctonus species were identified through the morphological and molecular studies: A. crassicauda, …

Morphological, Linear, And Geometric Morphometric Differences (Skull, Mandible, And Pelvis) Among Subspecies Of Talpa Levantis (Eulipotyphla: Talpidae) With Molecular Divergence (Mtdna And Nuclear Dna), Ahmet Yesari̇ Selçuk, Alaetti̇n Kaya, Haluk Kefeli̇oğlu

Turkish Journal of Zoology

In this study, we conducted comprehensive analysis to determine the morphological, linear morphometric, and geometric morphometric differences between three subspecies of Talpa levantis: T. levantis levantis, T. levantis dogramacii, and T. levantis transcaucasica. Molecular analyses including mitochondrial DNA (complete cyt b gene) and nuclear DNA (BRCA-2) were also used. The subspecies of T. levantis showed similarities in the parastyle of the first upper molar and the mesostyle of the second and third upper molars, as well as in the morphology of the pelvis and linear measurements of the ventral skull, mandible, and pelvis. T. levantis dogramacii and T. levantis levantis …

Using Thermal Camera Drones In Beef Cattle Roundup, Justin Wyatt Clawson, Eric Galloway, Shalyn Drake, Shawn Barstow, Ross Israelsen, Michael Pate

All Current Publications

Using drones with thermal sensors can be an effective tool in finding and collecting livestock from summer mountain ranges in the West. Drones can complete searches in much less time than required on horseback in demonstrated areas. Using drones reduces the workload of the rider and horse, saving time and energy and reducing the risk of injury. With proper training and certification, livestock producers can use drones to locate cattle and perform many other cost-cutting operations.

The Thai Journal of Veterinary Medicine

Taiping Island is an important sea turtle nesting site in Taiwan. However, information on the nesting ecology on Taiping Island is still limited. The present study was conducted between 26 April and 3 June 2023 with the objective of collecting primary data on the sea turtle species that nest on the island. A total of 20 individual nesting green turtles were identified. No other sea turtle species were recorded nesting during this period. Five percent of nesting sea turtles had external tumors. The mean curved carapace length of all nesting female turtles was 98.2 cm. A total of 28 clutches …

Empowering Young Innovators Through School-Based Agricultural Education: Insights From A Nigerian Secondary School Teacher, Mary O. Olumide-Oyaniyi

National Collaborative for Research on Food, Energy, and Water Education (NC-FEW)

Nigeria faces challenges like food insecurity and economic instability, worsened by a growing youth population. School-Based Agricultural Education (SBAE) engages youth in agricultural innovations. This study implemented SBAE principles in a Nigerian school, combining poultry farming and aquaculture. Students managed a poultry farm, using chicken droppings to breed maggots as feed for catfish in rainwater-filled tanks. The project enhanced students' skills, improved local food production, and engaged the community. Despite funding and management challenges, the initiative demonstrated SBAE's potential to empower youth and advance agricultural practices, offering a model for similar projects in other regions.

Salmon As An Ecological Pathway Of Contaminants Into Alaskan Food Webs, Miranda Brohman, Gretchen Roffler, Dimitri G. Giarikos, David Kerstetter, Amy C. Hirons

SECLER Data

Salmon are important fish taxa for humans and animals in hemiboreal and subarctic ecosystems. Trace elements and their marine food web bioaccumulation raises biomagnification and potential human health risk concerns. Sixteen trace element concentrations and their health risk assessments were determined in seven different tissues of two Southeast Alaska salmon species (chum, Oncorhynchus keta and pink, Oncorhynchus gorbuscha). Chum tissues had overall higher trace element concentrations compared to pink, which may be attributed to a difference of diets, generally longer-lived and spending more time in the open ocean. All kidney and liver samples exceeded the tolerable daily intake for …

Continuous Exposure To An Aversive Mixture: A Means Of Maintaining Aversion In Sheep Averted To Geigeria Ornativa O. Hoffm. (Vermeerbos) - An Assessment, Leendert D. Snyman

Poisonous Plant Research (PPR)

Establishing aversion to Geigeria ornativa only lasts for some time, after which the induced aversion disappears and sheep start eating G. ornativa again. This behavior is aggravated by the social influence of non-averted sheep in mixed grazing situations. Exposing sheep continuously to a so-called “aversive mixture”, containing an aversive substance (lithium chloride) and the sensory characteristics of the plant (hexane extract of G. ornativa) mixed with a tasty meal (maize meal), following an initial aversion treatment, resulted in sustained aversion to G. ornativa in the field. This method proved to be applicable to mixed grazing situations with averted and …

Influence Of Inselbergs On Bat Diversity In Afrotropical Ecosystems, Amanda Lee Grunwald

Dissertations and Theses

Humans are altering biological communities on local to global scales, driving profound changes in biodiversity and ecosystem functioning. However, significant gaps and biases in biodiversity data hinder our understanding of ecosystem interactions, making it challenging to develop effective, data-driven policies to protect remaining biodiversity. Bats, the second most species-rich groups of mammals, have a global distribution, and perform a broad array of vital ecosystem functions. Their diversity peaks in the tropics, where they often constitute more than 50% of mammal species diversity. The Afrotropics host substantial bat diversity, yet have historically been perceived as having lower species richness compared to …

Transcriptional Profiles Reveal Physiological Mechanisms For Compensation During A Simulated Marine Heatwave In Yellowtail Kingfish (Seriola Lalandi), Sharon E. Hook, Ryan J. Farr, Jenny Su, Alistair J. Hobday, Catherine Wingate, Lindsey Woolley, Luke Pilmer

Fisheries Research Articles

Background

Changing ocean temperatures are already causing declines in populations of marine organisms. Predicting the capacity of organisms to adjust to the pressures posed by climate change is a topic of much current research effort, particularly for species we farm or harvest. To explore one measure of phenotypic plasticity, the physiological compensations in response to heat stress as might be experienced in a marine heatwave, we exposed Yellowtail Kingfish (Seriola lalandi) to sublethal heat stress, and used the transcriptome in gill and muscle, benchmarked against heat shock proteins and oxidative stress indicators, to characterise the acute heat stress …

Restricted Feeding Of Goats During The Last Third Of Gestation And Trans-Generational Effects On Plasma Progesterone In Their Female Offspring, Andrew A. Ponter, Bérengère Laporte, Sabine Roussel, Winai Kaewlamun, Pascale Chavatte-Palmer, Christine Duvaux-Ponter

The Thai Journal of Veterinary Medicine

Feeding levels can vary in goat farms for several reasons. Underfeeding of gestating dairy goats can occur and may influence fetal follicle development and future reproductive performance in their offspring. The objective of this experiment was to study the effect of restricted feeding during the last third of gestation on some reproductive parameters in female offspring (F1). Two feeding groups were formed using 60 Alpine and Saanen dairy goats to produce the F1 female offspring. The control group (C, n = 30) was fed to requirements. The restricted group (R, n = 30) was given the same diet, but the …
