Cutaneous Microbiome Of Red Fox (Vulpes Vulpes) Infected With Sarcoptic Mange (Sarcoptes Scabiei), Jacqueline C. Robidoux Jan 2023

Cutaneous Microbiome Of Red Fox (Vulpes Vulpes) Infected With Sarcoptic Mange (Sarcoptes Scabiei), Jacqueline C. Robidoux

Honors Theses and Capstones

Sarcoptic mange is a parasitic skin disease that affects countless mammals worldwide, including red foxes (Vulpes vulpes). The symptoms, such as hair loss, crusting, and the number of mites, vary between individual foxes. Sarcoptic mange damages the skin barrier, which in turn disrupts the biodiversity of bacteria in the microbiome. It is unknown what the biodiversity of bacteria is at each stage of the disease. This experiment will compare the microbiomes of different samples with and without mange; in hopes to reveal a connection between the different severities of sarcoptic mange and the biodiversity of bacteria and fungi …

The Effects Of Warming Rate On The Thermal Tolerance Of A Southern Population Of Striped Bass (Morone Saxatilis), James Barrett

Honors College Theses

Climate change and global warming is an ever-growing concern for our environment and the survivability of the animals which inhabit it. With water temperatures expected to rise 2-3℃ in the next century, many aquatic organisms may be limited in their habitats based on their thermal tolerance (Lleras 2019). Southern populations of striped bass (Morone saxatilis) in the Southeastern United States could be some of the hardest hit by the effects of climate change due to their unusual life history as compared to the more northern populations of striped bass. These southern striped bass do not engage in coastal …

Research outputs 2022 to 2026

Dispersal patterns can dictate genetic population structure and, ultimately, population resilience, through maintaining gene flow and genetic diversity. However, geographical landforms, such as peninsulas, can impact dispersal patterns and thus be a barrier to gene flow. Here, we use 13 375 genome-wide single-nucleotide polymorphisms (SNPs) to evaluate genetic population structure and infer dispersal patterns of the Western Grasswren Amytornis textilis textilis (WGW, n = 140) in the Shark Bay region of Western Australia. We found high levels of genetic divergence between subpopulations on the mainland (Hamelin) and narrow peninsula (Peron). In addition, we found evidence of further genetic sub-structuring within …

A Review Of Methods For Detecting Rats At Low Densities, With Implications For Surveillance, Robert A. Davis, Philip J. Seddon, Michael D. Craig, James C. Russell

Research outputs 2022 to 2026

Invasive rats are the biggest threat to island biodiversity world-wide. Though the ecological impacts of rats on insular biota are well documented, introduced rats present a difficult problem for detection and management. In recent decades, improved approaches have allowed for island-wide eradications of invasive rats on small-medium sized islands and suppression on large islands, although both these still represent a formidable logistical and financial challenge. A key aspect of eradication or suppression and ongoing management is the ability to detect the presence of rats, especially at low densities. Here we review recent developments in the field of rat surveillance and …

Influence Of Temperature-Humidity Index, Calf Sex, And Parity On Gestation Length In Holstein Cows, Lazoumi Ouarfli, Abdelmadjid Chehma

Turkish Journal of Veterinary & Animal Sciences

The present study aimed to analyse the gestation length (GL) variability in locally born purebred Holstein dams (n = 1047), in a private farm, under Saharan climate. The overall GL mean was 278.73 ± 6.67 days. A general linear model revealed that the GL was significantly affected by calf sex (p = 0.035) with a minor increase of 0.19% in males, dam parity (p = 0.016) and calving season (p < 0.0001) including the shortest lengths recorded in heifers and during heat stress period. Moreover, a negative regression (-1.96%) in recent years was recorded in GL by the influence (p = 0.01) of years of birth, breeding, and calving of cows. Our findings show that cows that were inseminated and gave birth during the cold season (temperature-humidity index, THI < 74) had 11.54 days longer (p = 0.048) gestation period compared to animals that were inseminated and gave birth during the hot season (THI > 84). Similarly, the association (p = 0.003) between dam parity and calf sex revealed that the GL of multiparous cows that gave birth to male calves was higher (3.07 days) …

Does Euphrates Softshell Turtle Nest In Unfavourable Substratum? Description Of Nests From Euphrates River, Türkiye, Yusuf Bayrakci Jan 2023

Does Euphrates Softshell Turtle Nest In Unfavourable Substratum? Description Of Nests From Euphrates River, Türkiye, Yusuf Bayrakci

Turkish Journal of Zoology

Nest site selection differs among species based on a characteristic crucial to the embryo's survival. The identified nest-site characteristics of the Euphrates softshell turtle highlight that these turtles, like their other soft-shelled relatives, highly prefer the sandy substrate, even pure sand, to nest. However, alteration and loss of natural habitats for many decades limited the suitable oviposition sites along the Euphrates River. This study presents the uncharacteristic nest-site choice and the nesting time of Euphrates softshell turtle for the first time. I discovered four nests, as well as six unhatched eggs in a nest on 20 August 2017. This discovery …

A dense mucilage event occurred between November 2020 and August 2021 in the Marmara Sea, Turkey. In this study, the aim was to understand the effect of mucilage on coastal fish biodiversity. For this purpose, juvenile and small-sized adult fish species were sampled with an experimental beach seine at 12 equally-spaced stations around the Marmara Sea between November 2021 and April 2022. In total, 34 species belonging to 19 families were sampled. Approximately 70% of the total fish abundance were Atherina boyeri Risso, 1810, Chelon auratus (Risso, 1810) and Chelon saliens (Risso, 1810). Highest abundance was detected from S5 …
