Reproductive Performance And Its Association With Esr, Prlr, Fshb Genes In Indigenous “I” Pigs, Do Duc Luc, Phan Thi Tuoi, Nguyen Thai Anh, Do Thi Hue, Nguyen Hoang Thinh

The Thai Journal of Veterinary Medicine

Improving the reproductive performance of sows plays an important role in the pig industry, and it applies not only to commercial pigs but also to indigenous pigs. In this study, the polymorphisms of three genes, namely estrogen receptor (ESR), prolactin receptor (PRLR), and follicle-stimulating hormone beta subunit (FSHB) in the “I” pig population were investigated, and their associations with reproductive performance were evaluated. Ear tissue samples were collected from 151 fattening pigs and 126 sows across breeding farms in Vietnam for polymorphisms of the ESR, PRLR and FSHB genes. Three genotypes (AA, AB, and BB) were detected at the …

Assessing The Impact Of Lampenflora Growth On Invertebrate Distribution And Food Resource Use In Ryusen-Do Cave, Japan, Kazuhide Nakajima, Kanato Ando, Shuji Watanabe, Masuo Komukai

International Journal of Speleology

Subterranean spaces, such as caves with openings to the surface, represent unique environments characterized by limited resources derived from photosynthetic primary production. Consequently, organic inputs from organisms inhabiting above- and belowground habitats, such as bats, play a crucial role in maintaining cave ecosystems. However, in show caves converted into tourist attractions, environmental changes have progressed without sufficient ecological assessment. One important factor is the impact of photosynthetic organisms colonizing around artificial lights, known as lampenflora, on cave ecosystems. Lampenflora growth may influence invertebrate distribution and resource use; however, its impact on both aspects has been poorly evaluated. In this study, …

Comparison Of Sampling Methods For Estimation Of Aquatic Insect Diversity And Abundance Across Seasonal Gradients In A Southern U.S. River System, Albert Henry Gasperecz

LSU Master's Theses

Determination of benthic macroinvertebrate assemblage composition plays a vital role in assessment and management of lotic systems throughout the U.S. However, the validity of biomonitoring programs depends on accurate and precise measures of macroinvertebrate abundance, which in turn are dependent on sampling gears and protocols. The goal of this project was to assess how gear selection influences estimates of aquatic insect abundance and diversity, and how this selection can affect biological monitoring practices. I used 4 different gears in 3 southern Mississippi streams to aquatically and terrestrially collect aquatic insects seasonally throughout 2024. I identified and recorded all genera present …

Molecular Xenomonitoring For Early Detection Of West Nile Virus Circulation In New Jersey: A Field Validation Study, Viet-Linh Nguyen, Pratap Kafle

Graduate Student and Postdoctoral Fellow Symposium

West Nile virus (WNV) remains a persistent public health concern in New Jersey, yet current pooled-mosquito PCR surveillance often detects viral activity only after significant amplification, narrowing the window for timely intervention. Molecular xenomonitoring (MX), which is the detection of viral RNA in mosquito excreta or saliva deposited on honey-baited FTA cards, offers a non-destructive alternative that preserves nucleic acids at room temperature, passively captures signals from hundreds of mosquitoes per card, and has the potential to detect WNV circulation earlier than conventional surveillance by continuously sampling mosquito activity without the need for lethal collection. This project aims to (1) …

The Thai Journal of Veterinary Medicine

A 5-month-old intact male Pomeranian puppy was presented with a 2-week history of acutely swollen face, eyelids, lips, and muzzle. A physical examination revealed focal alopecia, folliculitis, and erythema on the muzzle, periocular, and perianal areas; crusts were also found around the muzzle. The puppy received monthly oral afoxolaner and milbemycin oxime. No ectoparasite was observed based on a trichogram test. Skin cytology revealed intracellular cocci and neutrophils. A skin biopsy taken from the muzzle revealed pyogranulomatous perifollicular dermatitis with epidermal spongiosis, intraepidermal pustules, and a superficial crust. This condition was diagnosed as juvenile cellulitis on the basis of age, …

Fenced And Feral: Farming And Spread Of Flowerhorn (Amphilophus Spp.) In Lake Sampaloc, Philippines, Janice A. Ragaza, Hannah Nicole Gasmen

Environmental Sustainability

This study examines the spread and ecological impact of invasive Flowerhorn cichlids (Amphilophus spp.) in Lake Sampaloc, Philippines, driven by both accidental release and intentional aquaculture practices. Field observations and literature reveal that these highly adaptable and aggressive fish outcompete native species, contributing to biodiversity decline amid increasing pollution, eutrophication, and microplastic contamination. Their phenotypic plasticity allows them to thrive in degraded environments, further exacerbating ecological imbalance. While local communities have begun utilizing Flowerhorns for ornamental trade and potential aquafeed production, such practices risk reinforcing their proliferation. The study highlights the need for integrated management strategies combining biosecurity, pollution control, …

This paper presents the reviews on the current state of research both domestically and internationally, systematically presenting the advancements of the economic impacts of animal diseases. The findings reveal that, (1) the economic impacts of animal diseases can be categorized into direct and indirect effects; however, a unified analytical framework has yet to be established. The “Epidemiology-Economics” approach is the primary analytical method for assessing the economic impacts of animal diseases. (2) …

Fire Scarring Does Not Significantly Impact Conifer Growth Response To Forest Fires In Utah, Connor B. Biser, Russell Torgersen, Otto Degroff, Steve Petersen

Student Works

BYU Wildfire Symposium 2026 - First Place Research Application, People's Choice Award

Wildfires are an increasingly prevalent disturbance in forests in the western United States, and play an essential role in ecosystem function. Micro-variations in fire dynamics and intensity can leave individual trees with varying levels of damage. We hypothesized that trees with fire-scars would suffer a growth depression directly following the disturbance. Core samples were taken for dendrochronological analysis from 185 conifers at 29 points, representing 11 fires from 6 years. Our findings showed a growth depression in the first year following the fire, with no significant difference between …

Nonnative Crayfish In Türkiye: Presence Records, Invasion Pathways, And Ecological Risks, Muzaffer Mustafa Harlioğlu

Turkish Journal of Zoology

The globalization of trade, aquaculture, and the ornamental pet industry has accelerated the transboundary movement of nonnative crayfish species, with significant ecological consequences. Türkiye, a biodiversity-rich country bridging Europe and Asia, has increasingly become a point of concern due to the rising presence of alien crayfish taxa introduced primarily via the aquarium trade and scientific research. This study investigates the presence records of nonnative crayfish species in Türkiye, identifies their likely introduction pathways, and outlines potential future outspread routes across the major freshwater basins of the country. Species such as Procambarus clarkii, Cherax quadricarinatus, C. albertisii, and Cambarellus patzcuarensis have …

Stage-Specific Growth Characteristics Of The Calanoid Copepod Invader Sinodiaptomus Sarsi​, Leonid Svetlichny, Kami̇l Mert Eryalçin, Melek İşi̇ni̇bi̇li̇r Okyar

Turkish Journal of Zoology

The population dynamics of the Asian invasive copepod Sinodiaptomus sarsi were  studied for four years after its introduction into an artificial pond in Kyiv (Ukraine) in  2020. The growth and development parameters of this species were measured under  laboratory conditions. From its first appearance in spring 2020, the abundance  of copepodite stages and adults increased from 3.5–5.2 individuals (ind.)  m–3 to 1057.8 ind. m–3 in June 2024, suggesting the successful establishment  of S. sarsi populations in this region. A characteristic feature of S.  sarsi development in ponds is a male-biased sex ratio in the later copepodite stages.  The sex ratio …

Morphometric And Reproductive Divergence Of Deep-Water Shrimps Plesionika Martia (A. Milne-Edwards, 1883) And P. Heterocarpus (A. Costa, 1871) Along A Depth Gradient In The Eastern Aegean Sea, Murat Özbek, Cengi̇z Koçak, Zafer Tosunoğlu

Turkish Journal of Zoology

This study provides a comparative analysis of two deep-water pandalid shrimp  species, Plesionika martia and P. heterocarpus, based on monthly samples collected  over one year in the Eastern Aegean Sea. Specimens were obtained from species-specific depth zones (550 m for P. martia and 350 m for P. heterocarpus) to examine  morphometric traits, sexual dimorphism, and reproductive patterns. A total of 4419  individuals were analyzed. Females were significantly larger and more abundant than  males (K–S test, p < 0.05), indicating pronounced sexual dimorphism. Length–weight relationships revealed negative allometric growth in both species, confirmed  by t-tests (p < 0.05). Reproductive activity differed markedly: P. martia showed a short  and distinct spawning period peaking in late autumn, whereas P. heterocarpus  displayed a prolonged, bimodal cycle with peaks in spring and summer. The gonadosomatic index (GSI) and the proportion of ovigerous females varied  significantly by season and species. A strong positive correlation between carapace  length and gonad weight was found, with a more linear relationship in P. martia and  greater variability in P. heterocarpus. Size at first maturity (L₅₀) was estimated at 22.3  mm CL for P. heterocarpus but could not be reliably determined for P. martia  due to limited small size data, likely reflecting ontogenetic depth segregation. The  consistent bathymetric separation between these species—also reported in the  Western Mediterranean—suggests ecological niche differentiation. Species-specific  management measures, including depth-based fishing restrictions and temporal  closures during reproductive peaks, are recommended to support the sustainable  exploitation of deep sea shrimp stocks in the region.

Frequencies And Roles Of Plants In The Diet Of Three Mesocarnivores (Canis Lupaster, Genetta Genetta, And Herpestes Ichneumon): Implications For Forest Regeneration In A North African Hot Spot (Algeria), Messaoud Bensidhoum, Abdelkrim Limane, Larbi Khifer, Ania Ben Ammar, Lylia Amrouche

Turkish Journal of Zoology

The Djurdjura National Park (PND, Algeria) is part of one of the world’s 36 biodiversity hot spots, recognised by the United Nations as a national biosphere  reserve. It contains the Darna primary forest, a key habitat for several mesocarnivore  mammals, including the golden wolf (Canis lupaster), the common genet (Genetta  genetta) and the ichneumon mongoose (Herpestes ichneumon). Although their diets  are primarily based on animal prey, these carnivores exhibit both qualitative and  quantitative reliance on plants, a pattern that merits thorough documentation. We  analysed 30 scats per species per month over four years (1440 scats per species).  More than 35% …

Urban Areas Are Associated With Earlier Breeding Timing In American Robins, Lola Hackle, Jennifer Wickes, Elise Mittlestat, Ashley Stine, Keegan Abeson, Carolina Villalona, Mikus Abolins-Abols

The Cardinal Edge

Climate change and urban environment have been shown to affect bird reproductive timing. In particular, urban development can create the so-called “heat islands” – urban areas that are hotter than the surrounding environment. While the primary cue birds use to time their reproduction is daylength, birds also use temperature as a supplementary cue to fine-tune their reproductive timing. Change in the timing of breeding may impact the survivability of nestlings due to temperature fluctuations and food availability. The American Robin (Turdus migratorius) is a widespread songbird in North American cities and rural areas. We sought to see if urban heating …

Characterisation Of Pouch Secretions From Breeding Tasmanian Devils, Manujaya W. Jayamanna Mohottige, Emma Peel, Angéla Juhász, Mitchell G. Nye-Wood, Katherine Belov, Michelle L. Colgrave, Carolyn J. Hogg

Research outputs 2022 to 2026

Tasmanian devils (Sarcophilus harrisii), like all marsupials, give birth to altricial young. Here we employ proteomic analysis to identify components of devil pouch secretions that may contribute to offspring survival and development. Proteins were extracted from five samples and analysed by liquid chromatography-tandem mass spectrometry. Peptide-level evidence revealed proteins involved in a diverse set of immune pathways, including those mediating iron-ion transport, defence responses to bacteria, innate immune responses, and antigen processing. A core set of 200 proteins was identified across at least three samples, 63 of which were associated with antimicrobial or immunoregulatory functions. These included immunoglobulins, components of …

Spatiotemporal Patterns Of Occupancy By Pygmy Rabbits (Sylvilagus Idahoensis), Kevin A. Royal, Brock R. Mcmillan, Kimberly A. Hersey, Steven L. Petersen, Randy T. Larsen

Student Works

The pygmy rabbit (Sylvilagus idahoensis) is a species of conservation concern that has declined due to fragmentation and loss of essential habitat, primarily sagebrush-steppe. Pygmy rabbits are currently under review for listing under the U.S. Endangered Species Act (ESA) and consequently require a clearer understanding of current distribution and patterns of occurrence in big sagebrush (Artemisia tridentata) habitats. From 2024 to 2025, we surveyed for pygmy rabbits using remote cameras at several historically occupied sites in Utah, USA, to understand patterns of activity and occupancy. We also compared current estimates of occupancy to historical data collected approximately 20 years ago. …

The aim of this paper is to present information to help reduce the risk of poisoning. The paper emphasizes the particular plant communities in which these plants grow. Some of these plants are endemic, growing on specific soils or specific ecological sites. Others are distributed more broadly throughout a vegetation type. A few of the plants are widespread, ranging over several broad ecosystems. In diagnosing poisoning, it is important to know what plants are expected to grow in the communities …

Species Sorting And Spatial Effects In Hyporheic Invertebrate Functional Groups, Benjamin T. Hutchins, Zoey B. Chanin, Kathryn E. Perez, Peter H. Diaz, Benjamin F. Schwartz

School of Integrative Biological & Chemical Sciences Faculty Publications

Invertebrate communities in the hyporheic zone are structured by metacommunity processes including environmental filtering and spatial effects (e.g., dispersal). We investigated how these processes differentially influence two functional groups: groundwater-obligate invertebrates (stygobionts) and benthic insects. We predicted that environmental filtering would dominate for insects, while spatial effects would prevail for stygobionts. We collected 76 samples from 28 hyporheic sites along 109 km of the Rio Grande, Texas, USA, enumerating 54,508 individuals across 80 taxa. Concordance analysis and RDA revealed two communities: one dominated by insects, and another by crustaceans and soft-bodied organisms, including all stygobionts. In linear models, insect richness …
