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 …

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 …
The Effects Of Active Substances Of Clinically Important Drugs On The Survival, Development, And Some Adult Traits Of Drosophila Melanogaster Meigen (Diptera: Drosophilidae), Gökçe Üstündağ, Kemal Büyükgüzel, Ender Büyükgüzel
Turkish Journal of Zoology
Drosophila melanogaster Meigen (Diptera: Drosophilidae) was used as a model organism and fed on an artificial diet with different clinically important drugs under laboratory conditions. The effects of fluconazole, acyclovir, and piperazine on the survivorship, development, adult longevity, fecundity, and hatching rate of the insect were investigated. The results showed that the highest concentration of fluconazole (1250 mg/L) significantly decreased both the rate of larvae reaching the 3rd instar and the rate of pupation from 93.00 ± 2.95% to 11.00 ± 2.59% (χ2 = 134.696; df = 1; p = 0.0001). The highest concentration of acyclovir (200 mg/L) significantly reduced …

Gulf and Caribbean Research
Once vibrant ecosystems, coral reefs are degrading at unprecedented rates due to natural and human—induced disturbances, necessitating immediate restoration and conservation efforts. Evaluating the success of these projects often involves assessing changes in reef biodiversity. Bioacoustics has emerged as a promising, non—invasive method for such evaluations, though its efficacy remains debated. This study aimed to determine whether the diurnal soundscapes of restored coral reefs are consistent across different time frames (months) and spatial scales (reefs), which is crucial for developing reliable monitoring tools for reef health. To achieve this, 2 commonly used acoustic indices, the Acoustic Complexity Index (ACI) and …

If You Give A Tadpole A Chemosensory Stimulus: Detection Of Invasive Predatory Cues And Signs Of Conspecific Communication In Pseudacris Sierra Tadpoles, Faben Tesfazion
Scripps Senior Theses
Amphibians are at disproportionately higher risks of extinction than all other vertebrate classes, and a major causing factor is invasive predation. The American bullfrog (Lithobates catesbeianus), native to Eastern North America, is a notorious invasive species which preys on native Sierran treefrogs (Pseudacris sierra) in Northern and Central California. These treefrogs have yet to be placed on any Special Animals List, suggesting the presence of adopted behaviors against predation. Past studies have documented the importance of chemical sensing in anuran tadpoles as predator detection tools. This study tests if Sierran treefrog tadpoles can recognize invasive chemical …

Undergraduate Scholarship and Creative Works
In the early 1980s Diadema antillarum, or the long-spined urchin, was hit by a catastrophic mass mortality event across the western Atlantic and Gulf of Mexico, inclusive of the Florida Keys. The cause of this die-off event was likely triggered by a pathogen or environmental stressor that decimated native populations by up to 98%. The species has not yet fully recovered and is struggling with recruitment success which is why it may benefit from an ex-situ recovery program. In this study, I used single nucleotide polymorphisms (SNPs) to identify genetic variation and analyze parentage in a captive population of …

Behavioral Observations And Analysis Of Twix: The Cape Porcupine At The Lake Superior Zoo, Erin Davidson
Scripps Senior Theses
The three main goals of zoos are outlined as: education, conservation, and research. In our modern world, the focus of zoos has shifted away from simply housing animals, and towards how we can best promote proper animal welfare for individuals in human care. Animal welfare can be defined as the “mental health” of non-human species of fauna, and is greatly influenced by the stressors within the environment, as well as the option of choosing how to interact with and respond to the environment. Animals housed in zoos are presented with unique stressors that they often do not choose to experience, …

UNF Graduate Theses and Dissertations
As conservation and education institutions, modern zoos balance the needs of animals with the interests of visitors through several strategies which can increase animal wellbeing and improve visitor experience. Environmental enrichment is frequently employed to increase the suitability of anthropogenic environments for zoo-housed animals, such as through walkthrough habitats and free-flight aviaries. While habitats such as these are important for visitor experience and can be enriching to animals, there are also wellbeing considerations for these spaces. Walkthrough habitats can be a potential source of fear and stress for animals, as shown by increased frequencies of vigilance, undesirable behavior, and aggression. …

Bovine Serum Albumin (Bsa) Impacts Morphology Of Fowler’S Toad (Anaxyrus Fowleri) Sperm During Short-Term Cold Storage, Jane A. Dill, Michelle K. Roy, Renato E. Naranjo, Andrew J. Kouba, Carrie K. Vance
Endeavors: Mississippi State Undergraduate Research Journal
Short-term cold storage of amphibian sperm is a valuable technique for overcoming challenges associated with asynchronous gamete release during breeding events or for transferring sperm between institutions for genetic management. Unfortunately, sperm longevity declines over time even when kept cool. Maintaining sperm form and function is critical to achieving the highest possible fertilization rates. Thus, cold storage of amphibian sperm would benefit from the addition of compounds that could extend their quality, improve fertilization and result in more offspring. One such compound is bovine serum albumin (BSA), which provides membrane stabilization, prevents lipid peroxidation of cells, protects against free radical …

Investigating The Presence Of Individuality And Behavioral Syndromes In Northern Cottonmouths (Agkistrodon Piscivorus), Joshua Lowy
Graduate Theses/Dissertations
Within the last 15 ̶20 years, research on behavioral syndromes has seen a surge in prominence and popularity in behavioral ecology, revealing that many animals exhibit individually consistent behavioral tendencies. Behavioral syndromes occur when behavioral traits are correlated with one another within the same context or across different contexts. Despite new appreciation for the ecological, evolutionary, and conservation implications of behavioral syndrome data, the taxonomic breadth of studies is uneven. Snakes are underrepresented within squamate reptiles and, among venomous species, only two rattlesnakes (Crotalus) have been investigated for evidence of behavioral syndromes. My study investigates individuality and the presence of …

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–
Populations of zoo-managed African elephant (Loxodonta Africana) exhibit substantial individual- and population-level variation in reproductive success, yet research has largely focused on females, leaving male fertility poorly understood. Subfertility in bulls, characterized by low libido and inconsistent semen quality, poses significant challenges to genetic management and long-term population sustainability. This study a) systematically evaluates semen quality, b) identifies physiological, behavioral, social, and environmental determinants of fertility, and c) advances ex situ conservation through the expansion of the African elephant sperm bank. Between January 2023 and July 2025, 209 semen collection events were conducted from 13 sexually mature bulls …

Assessing Intra-Seasonal Changes In Summer Elk Diet Composition, Ava E. Window
Undergraduate Theses, Professional Papers, and Capstone Artifacts
Elk (Cervus canadensis) require adequate forage to fulfill their seasonal nutritional requirements. Elk undergo their highest nutritional demands during summer to support critical life functions such as late gestation, lactation, and juvenile growth. However, variations in plant phenology significantly influence the quality and quantity of forage available to elk during the summer season. As summer advances and plant communities mature, forage quality often declines, leading to a landscape that imposes greater nutritional constraints on elk. As a result, prior research on elk foraging habits has primarily focused on late summer. This has led to limited knowledge surrounding the …
