Migratory Movements And Home Ranges Of Geographically Distinct Wintering Populations Of A Soaring Bird, Ryo Ogawa, J. Brian Davis, D. Tommy King, L. Wes Burger, Bronson K. Strickland, Marsha A. Sovada, Guiming Wang, Fred L. Cunningham

United States Department of Agriculture Wildlife Services: Staff Publications

Migratory soaring birds exhibit spatiotemporal variation in their circannual movements. Nevertheless, it remains uncertain how different winter environments affect the circannual movement patterns of migratory soaring birds. Here, we investigated annual movement strategies of American white pelicans Pelecanus erythrorhynchos (hereafter, pelican) from two geographically distinct wintering grounds in the Southern and Northern Gulf of Mexico (GOM).We hypothesized that hourly movement distance and home range size of a soaring bird would differ between different geographic regions because of different thermals and wind conditions and resource availability. We calculated average and maximum hourly movement distances and seasonal home ranges of GPS-tracking pelicans. …

Invasive Rodent Responses To Experimental And Natural Hurricanes With Implications For Global Climate Change, Aaron B. Shiels, Gabriela E. Ramírez De Arellano, Laura Shiels

United States Department of Agriculture Wildlife Services: Staff Publications

Hurricanes cause dramatic changes to forests by opening the canopy and depositing debris onto the forest floor. How invasive rodent populations respond to hurricanes is not well understood, but shifts in rodent abundance and foraging may result from scarce fruit and seed resources that follow hurricanes. We conducted studies in a wet tropical forest in Puerto Rico to better understand how experimental (canopy trimming experiment) and natural (Hurricane Maria) hurricane effects alter populations of invasive rodents (Rattus rattus [rats] and Mus musculus [mice]) and their foraging behaviors. To monitor rodent populations, we used tracking tunnels (inked and baited cards …

Improving Efficiency Of Prairie Dog Surveys By Using A Small Copter Drone, Aaron B. Shiels, J. W. Fischer, Danika Spock, Meagan Allira

United States Department of Agriculture Wildlife Services: Staff Publications

Prairie dogs are an accessible and enjoyed wildlife species in Colorado that require occasional surveys because populations can change abruptly due to plague outbreaks or human-induced control. We evaluated the use of small copter drones at four prairie dog colonies on Open Space and Mountain Parks lands, City of Boulder, to determine if this methodology improves efficiency over ground-based survey methods. We counted prairie dogs and burrows using two types of drones (DJI Matric 210 and Autel Evo II) at altitudes 100', 150', and 400' (burrows only). We recorded video and merged still images into orthomosaics prior to having USDA …

Susceptibility Of Wild Canids To Sars-Cov-2, Stephanie M. Porter, Aim E. Hartwig, Helle Bielefeldt-Ohmann, Angela M. Bosco-Lauth, J. Jeffrey Root

United States Department of Agriculture Wildlife Services: Staff Publications

We assessed 2 wild canid species, red foxes (Vulpes vulpes) and coyotes (Canis latrans), for susceptibility to SARS-CoV-2. After experimental inoculation, red foxes became infected and shed infectious virus. Conversely, experimentally challenged coyotes did not become infected; therefore, coyotes are unlikely to be competent hosts for SARS-CoV-2.

Throughout the COVID-19 pandemic, multiple instances of natural infections with SARS-CoV-2 have been reported in pet dogs, likely after exposure to an infected human (1–3). Domestic dogs appear to be minimally susceptible to SARS-CoV-2, as indicated by experimental inoculations resulting in reverse transcription PCR–positive samples and low titer antibody responses but no clinical …

Exploring The Value Of A Global Gene Drive Project Registry, Riley I. Taitingfong, Antoinette J. Piaggio, Cinnamon S. Bloss, Et Al.

United States Department of Agriculture Wildlife Services: Staff Publications

Recent calls to establish a global project registry before releasing any gene-drive-modified organisms (GDOs) have suggested a registry could be valuable to coordinate research, collect data to monitor and evaluate potential ecological impacts, and facilitate transparent communication with community stakeholders and the general public. Here, we report the results of a multidisciplinary expert workshop on GDO registries convened on 8–9 December 2020 involving 70 participants from 14 countries. Participants had expertise in gene drive design, conservation and population modeling, social science, stakeholder engagement, governance and regulation, international policy, and vector control; they represented 45 organizations, spanning national and local governmental …

The Question Is Not “Can Humans Talk?” Or “Can They Suffer?” But “Can They Reason?”, Clive Phillips

Animal Sentience

In their target article, Rowan et al (2022) make a welcome attempt to chart the development of Western progress over the past two hundred years toward formally recognizing that animals feel. They outline the heroic efforts of Compassion in World Farming to gain for animals the status of sentient beings rather than merely human property. A broader view exists, from human prehistory to the present day, in which animals have been (and still are) understood to be sentient by indigenous peoples as well as by some Eastern religions. Growing recognition in the West that animals feel represents a new age …

Why The Recognition Of Sentience Is So Important For Animal Welfare, Mark Jones

Animal Sentience

Rowan et al. (2022) provide a useful summary of the history and development of the philosophical, public, and legal recognition of animal sentience and its importance in improving the welfare of animals. Here I argue for the incorporation of the precautionary principle in sentience recognition, and the wider significance of sentience recognition to the current climate, biodiversity and human health crises.

Role Of Host Restriction Factors On Porcine Reproductive And Respiratory Syndrome Virus (Prrsv) Replication, Pratik Katwal

Electronic Theses and Dissertations

In this study, the role of IFITM3 on PRRSV replication was studied in vitro by expressing exogenous IFITM3 in MARC-145 cells. An average of 31% reduction in PRRSV N protein expression and an average of 5.4 fold decrease in virus titer in the supernatant were observed in IFITM3 overexpressing cells as compared to vector control cells at 24 hours post infection (hpi). Moreover, there was a positive correlation between interferon- induced IFITM3 up-regulation and reduced PRRSV replication. To determine the role of endogenous IFITM3 in PRRSV replication, siRNA induced knockdown of IFITM3 was employed. RT-PCR validated the successful silencing of …

Factors Influencing Intestinal Parasite In Black-And-White Ruffed Lemurs (Varecia Variegata), Eliette Noromalala

All Master's Theses

Ecological factors, such as feeding behavior and climatic seasonality, might influence intestinal parasite infection and patterns in non-human primates. Here, we examined if frugivory levels and climate (i.e., temperature and rainfall) were associated with parasite patterns in black-and-white ruffed lemurs (Varecia variegata). Feeding data using 5-min focal sampling, climate data, and fecal samples from V. variegata (n = 23) at the “Mangevo” site were collected from February through May 2019. Microscopic examinations of fecal flotation and sedimentation were done to identify and count parasites. Nematoda (Callistoura vauceli, and Strongyloides sp.) Ciliophora (Balantidium sp.), Coccidia ( …

Exo-Sir: An Epidemiological Model To Analyze The Impact Of Exogenous Spread Of Infection, Nirmal Kumar Sivaraman, Manas Gaur, Shivansh Baijal, Sakthi Balan Muthiah, Amit Sheth

Publications

Epidemics like Covid-19 and Ebola have impacted people's lives significantly. The impact of mobility of people across the countries or states in the spread of epidemics has been significant. The spread of disease due to factors local to the population under consideration is termed the endogenous spread. The spread due to external factors like migration, mobility, etc. is called the exogenous spread. In this paper, we introduce the Exo-SIR model, an extension of the popular SIR model and a few variants of the model. The novelty in our model is that it captures both the exogenous and endogenous spread of …

Determination Of Plant-Specific Retrotransposons In Chicken, Levent Mercan, Ci̇hat Erdem Bülbül, Fati̇h Bi̇lgi̇, Sevgi̇ Marakli

Turkish Journal of Veterinary & Animal Sciences

Mobile genetic elements are also known as transposons, comprising a significant proportion of plant and animal genomes. Retrotransposons, a class of transposons, move copy and paste mechanism and, therefore, cause genome obesity. Moreover, the transferability of retrotransposons within and between different kingdoms has provided valuable information for evolutionary relationships in addition to detailed knowledge about genomes. We identified barley-specific retrotransposons (Nikita and Sukkula) and determined polymorphism ratios of these retrotransposons in a chicken genome for the first time to gain new insights for retrotransposons found in different genomes. Transposon sequences belonging to chicken and barley genomes were also investigated to …

Bayesian Genomic Prediction Of Junctional Epidermolysis Bullosa In Sheep, Burak Karacaören

Turkish Journal of Veterinary & Animal Sciences

Junctional epidermolysis bullosa (JEP) is a heritable skin and mucosa disorder in association with mendelian mutations in sheep. The purpose of this investigation is to explore the relationship between different priors, linkage disequilibrium, and single nucleotide polymorphism (SNP) selection methods and accuracy of Bayesian GP of JEP in sheep. Ninety-two Spanish Churra sheep breed genotyped by 40668 SNP markers. Bayes C? was shown to have slightly higher predicted accuracy [0.724 (0.113)] by unselected data. Prediction performance of the Bayesian GP models was found to be similar after correction for LD. There was a significant difference between predicted accuracies due to …

A Game Theoretic Approach To Design Mating Programs For Livestock, Ebru Ergüneş Berki̇n, Hasan Önder, Özgür Hakan Aydoğmuş

Turkish Journal of Veterinary & Animal Sciences

In this study, we proposed a new game theoretic method to design a mating program. The index and game theoretic methods were applied with calculated breeding values using pedigree on two different data sets whose economic traits consist of negative (milk yield and fat percentage) and positive (birth and weaning weight) genetic correlated data. For the negative genetic correlated data set, even if total expected benefits were equal for two methods, mating programs were changed, and the coefficient of variation obtained using the game theoretic method was smaller than that of the index method. This result showed that the expected …

Effects Of Centrifugation And Washing Of Freeze-Thawed Blood On Isolated Dna Characteristics, Mevlüt Arslan

Turkish Journal of Veterinary & Animal Sciences

DNA isolations from the whole blood are commonly performed to obtain DNA for molecular research and diagnostics. Generally, blood samples are taken into anticoagulant tubes and stored in deep freezers until DNA isolation. In fresh blood, pretreatments or leukocytes preparations can be performed and suggested for advanced DNA isolation. However, similar applications in freeze-thawed blood (FTB) have not been shown yet. In the study, centrifugation and washing of FTB were applied as pretreatment before DNA isolations, and their effects on isolated DNA characteristics including DNA integrity, quality, quantity, mitochondrial (mt), and nuclear (n) DNA levels were investigated. Microscopic and flow …
