United States Department of Agriculture Wildlife Services: Staff Publications
We investigated the landscape epidemiology of a globally distributed mammal, the wild pig (Sus scrofa), in Florida (U.S.), where it is considered an invasive species and reservoir to pathogens that impact the health of people, domestic animals, and wildlife. Specifically, we tested the hypothesis that two commonly cited factors in disease transmission, connectivity among populations and abundant resources, would increase the likelihood of exposure to both pseudorabies virus (PrV) and Brucella spp. (bacterial agent of brucellosis) in wild pigs across the Kissimmee Valley of Florida. Using DNA from 348 wild pigs and sera from 320 individuals at 24 sites, we …

A New Vine Snake (Reptilia, Colubridae, Oxybelis) From Peru And Redescription Of O. Acuminatus, Robert C. Jadin, Michael J. Jowers, Sarah A. Orlofske, William E. Duellman, Christopher Blair, John C. Murphy
Publications and Research
The Brown Vine Snake, Oxybelis aeneus, was until recently considered a single species, distributed from southern Arizona through the Neotropics into southeastern Brazil. However, newly conducted research restructured the species with a substantial taxonomic revision, recognizing five additional taxa (i.e. O. koehleri, O. microphthalmus, O. potosiensis, O. rutherfordi, O. vittatus) in this species complex. This revision focused on populations in North America, Central America, and northern South America while neglecting the southern portion of its distribution. Here, we examine the taxonomic history of the complex and use it along with specimen data to resurrect O. acuminatus from southeastern Brazil. Finally, …
Prenatal And Postnatal Nutrition Influence Pancreatic And Intestinal Carbohydrase Activities Of Ruminants, Ronald J. Trotta, Kendall C. Swanson
Prenatal And Postnatal Nutrition Influence Pancreatic And Intestinal Carbohydrase Activities Of Ruminants, Ronald J. Trotta, Kendall C. Swanson
Animal and Food Sciences Graduate Research
In ruminant livestock species, nutrition can play an important role in the long-term programming of gastrointestinal function. Pancreatic and small intestinal digestive enzymes are important for postruminal digestion of carbohydrates and protein. Carbohydrases have been shown to respond to changes in the level of feed intake and the dietary inclusion of specific nutrients, including arginine, butyrate, folic acid, fructose, and leucine. Understanding how diet influences enzyme development and activity during prenatal and postnatal life could lead to the development of dietary strategies to optimize offspring growth and development to increase digestive efficiency of ruminant livestock species. More research is needed …

Single-Locus Species Delimitation And Ecological Niche Modeling Provide Insights Into The Evolution, Historical Distribution, And Taxonomy Of The Pacific Chorus Frogs, Robert C. Jadin, Sarah A. Orlofske, Tereza Jezkova, Christopher Blair
Publications and Research
The Pacific chorus frogs are a complex of three wide-ranging species (i.e. Hyliola hypochondriaca, Hyliola regilla, Hyliola sierra) whose current taxonomy remains unresolved. We conducted species delimitation analyses of these taxa using fragments of the cytochrome b and 12S–16S mtDNA genes to assess the species diversity. Importantly, we included samples from new locations throughout the range to better understand species distributions and identify potential contact zones among clades. Our analyses revealed three slightly parapatric but distinct species-level clades. Molecular dating revealed that these species began diverging in the Pleistocene c. 1.4 Mya with H. hypochondriaca and …

Johne’s disease is a chronic, contagious, zoonotic disease that affects numerous species including livestock and sometimes humans. The disease is globally distributed in sheep populations and caused by Mycobacterium avium Subsp. paratuberculosis (MAP). A previous genome-wide association study identified single nucleotide polymorphism (SNP) markers associated with OJD serostatus in CD109, PCP4, and SEMA3D genes. Our aim was to evaluate the same markers for association with OJD seroprevalence in Turkish sheep in a retrospective matched case-control study. The serological status for OJD in 1801 sheep was determined for four native and four composite breeds from three research flocks. One hundred eleven …

Accuracy Of Gebv Of Sires Based On Pooled Allele Frequency Of Their Progeny, Napoleón Vargas Jurado, Larry A. Kuehn, John W. Keele, Ronald M. Lewis
Roman L. Hruska U.S. Meat Animal Research Center: Reports
Despite decreasing genotyping costs, in some cases individually genotyping animals is not economically feasible (e.g., in small ruminants). An alternative is to pool DNA, using the pooled allele frequency (PAF) to garner information on performance. Still, the use of PAF for prediction (estimation of genomic breeding values; GEBVs) has been limited. Two potential sources of error on accuracy of GEBV of sires, obtained from PAF of their progeny themselves lacking pedigree information, were tested: (i) pool construction error (unequal contribution of DNA from animals in pools), and (ii) technical error (variability when reading the array). Pooling design (random, extremes, K-means), …

Roman L. Hruska U.S. Meat Animal Research Center: Reports
When the number of horn flies that blood feed on cattle exceeds the economic threshold, they can adversely affect the health and wellbeing of their hosts. Excessive horn fly burdens also lead to reduced weight gain and, consequently, diminished profits for livestock producers. Effective management and treatment require reliable surveillance methods for estimating the degree of horn fly burden (i.e., counting the number of flies on cattle). Traditionally, these estimates are obtained through human visual estimation, either in-person or by counting images on a photo; however, these methods are costly both in terms of time and labor and are prone …

Anurans are the most suitable vertebrate group to see the development and also evolution in the skull, compared to other terrestrial vertebrates as they show highly derived morphology. For this reason, the cranium of anurans has been widely used for analyzing e.g., development and integration, evolutionary history, phylogenetic relationships, sexual dimorphism; and for taxon determination. We applied geometric morphometric techniques and then multivariate statistical analyses to see the skull size and shape variations in closely related Bufo species (B. bufo and B. verrucosissimus) inhabiting Turkey. Females have larger skull than males for both species. Ventral skull size of males differed …

Antimicrobial resistance (AMR) is a significant threat to human health globally. Diseases caused by AMR are getting more challenging to cure due to the increasing rate of resistance of microbial pathogens. Drugs formulated with antimicrobial peptide (AMP) can be applied to treat these diseases. AMPs are found naturally within organisms, especially amphibians, and is related to the high adaptability of defence mechanisms against various pathogens and predators in the environment. This review focuses on the current status of research works and the different approaches applied to stimulate and collect amphibian secretions, extract and identify peptides, and conduct antimicrobial assays.

This study evaluates the Black Sea anchovy population infected by parasitic Ascaridoid Nematode larva in the Southern Black Sea. It assesses the larva?s effect on fish body condition, energy stored in the body, and anchovy growth. For this, anchovies sampled on July 10-31, 2018, from 30 different stations were examined, and 11.8% of the 825 anchovies were found infected. The observed infection rate was higher on the western side of the study area, suggesting that this rate may be used as a biomarker for the western stock. Age and size of the anchovies play a significant role in the prevalence. …

The common vole Microtus arvalis (Pallas, 1778) is the most widespread Microtus species. It has two forms - the European arvalis form (2n: 46, NF: 84) and the Asian obscurus form (2n: 46, NF: 72). The present study aimed to clarify the taxonomic status of M. arvalis populations distributed in Eastern Turkey, Europe and Asia by analysing two mitochondrial (CYTB and COX1) and one nuclear (IRBP) markers. Phylogenetic dendrograms (median-joining networks and Bayesian trees) constructed using the mitochondrial markers clearly separated the Anatolian population from the European and Asian populations. Contrarily, any explicit differentiation was not shown in IRBP analyses. …

The Striped Hyaena, Hyaena hyaena, extends its distribution in the north into Turkey, where it has always been rare. In a status assessment conducted by Kasparek et al. in 2004, it was shown that the species is at the brink of extinction. We compiled information from different sources including a press survey and camera trapping in different parts of the country. The situation has even deteriorated since then. The population has strongly decreased, in particular, in the Marmara and Mediterranean regions, and presently the species survives in Western Anatolia only in some small relict populations in Manisa, İzmir, Muğla, and …
