Is Mitigation Translocation An Effective Method For Reducing Laysan Albatross–Military Aircraft Collisions?, Brian E. Washburn, Katherine D. Rubiano, William P. Bukoski
Human–Wildlife Interactions
Wildlife–aircraft collisions (wildlife strikes) pose a serious risk to civil and military aircraft. Each year, Laysan albatrosses (Phoebastria immutabilis) attempt to establish a breeding colony on the airfield at the U.S. Navy’s Pacific Missile Range Facility (PMRF) located on the island of Kaua‘i, Hawai‘i, USA, resulting in a hazard to safe military aircraft operations at this facility. A long-term management program, with an emphasis on mitigation translocation (e.g., live-capture and translocation away from the area) of problematic individuals, has been conducted by the U.S. Department of Agriculture, Wildlife Services. However, the efficacy of mitigation translocation as a nonlethal …

Comparing Alternative Developmental Modes: Structure And Gene Expression In The Olfactory System Of Plethodontid Salamanders, Giuseppina S. Lanzilli
Cal Poly Humboldt theses and projects
The olfactory system of extant amphibians changes as the animal transitions from a fully aquatic to a terrestrial lifestyle at metamorphosis. Cellular morphology of the nose and expression patterns of olfactory genes in the nasal cavity have been examined for a variety of frogs and salamanders, but among plethodontid salamanders, molecular data are available only for Plethodon shermani. Using standard histology and micro-CT reconstruction, I investigated the structure of the olfactory organs of larvae, juveniles, and adults of six plethodontid species, with terrestrial, streamside, semiaquatic, and aquatic adults. The overall structure of the olfactory cavity was generally similar across …

Pond Characteristics That Influence Oviposition Site Selection By Two Pond-Breeding Amphibians, Northern Red-Legged Frog (Rana Aurora) And Northwestern Salamander (Ambystoma Gracile), Jessica Jones
Cal Poly Humboldt theses and projects
Pond-breeding amphibians connect aquatic and terrestrial habitats through their biphasic life cycle, and understanding pond characteristics that support oviposition sites for multiple species is important for amphibian conservation. Two common amphibians in the Pacific Northwest, Northern red-legged frog (Rana aurora) and Northwestern salamander (Ambystoma gracile) often oviposit in the same pond; however, prior studies have focused on pond use by one species or the other, but not both together. I surveyed pond and oviposition site characteristics of 26 ponds in Humboldt County, CA, 10 of which were used only by R. aurora and 16 of which …

Characterizing The Habitat Use Of Pacific Coast Feeding Group Gray Whales (Eschrichtius Robustus) And The Spatial And Temporal Variability Of Their Benthic And Planktonic Invertebrate Prey In Northern California, Robyn E. Norman
Cal Poly Humboldt theses and projects
As opportunistic foragers, the Eastern North Pacific population (~20,000) of gray whales (Eschrichtius robustus) feed on diverse benthic and planktonic invertebrates in northern Alaska foraging grounds before they undertake one of the largest yearly migrations of any mammal to breed in Baja California, Mexico. While most of the population travels to the summer foraging grounds in Alaska, a sub-group of whales (~230) called the Pacific Coast Feeding Group (PCFG) summer between British Columbia, Canada, and northern California. The diet of PCFG whales typically includes high-density and/or high-caloric prey items like mysids and diverse species of amphipods, yet a …

An Updated Outline For Clearing And Staining Of Preserved Specimens, Sadie E. Smith
Honors Theses and Capstones
This protocol outlines a enhanced clearing and staining procedure for persevered specimens, focusing on the visualization of cartilage and bone in small taxa. With origins from O. Shultze's diaphonization methodology in 1897, the process of clearing and staining improves the clarity and contrast of intricate tissues. It is essential for studies in developmental biology, histology and anatomy. This protocol covers the key steps of the process while detailing the materials, solutions and estimated timeline for each step pertaining to specific taxa. The aim of the protocol is to standardize and provide guidance for procedures in the Biological Sciences department at …

Comparative Study On Reproductive Behavior Of Three Thai Indigenous Apple Snails Pila Celebensis (Quoy & Gaimard, 1834), P. Pesmei (Morlet, 1889) และ P. Virescens (Deshayes, 1824), Supunya Annate
Chulalongkorn University Theses and Dissertations (Chula ETD)
Species of the Thai indigenous apple snail genus Pila Röding, 1798 are undergoing population decline. Accordingly, their conservation is needed, but the lack of knowledge of their reproductive biology is a significant obstacle to implementing conservation measures. Therefore, this study analyzed the mating and egg-laying behavior of three of the five Thai indigenous apple snails: P. celebensis, P. pesmei, and P. virescens using continuous video recording under laboratory conditions. In addition, the egg-laying behavior of P. virescens in a seminatural habitat was observed in the rainy season of 2023. Moreover, their egg, egg mass, incubation time, and hatchling characteristics were …

Unsung Heroes In Conservation: Evaluating The Limitations Faced By New England Wildlife Rehabilitation Centers And Proposing Solutions For Their Support And Recognition, Shaylee M. Sarmiento
Honors Theses and Capstones
Wildlife rehabilitation is an often-unacknowledged practice within the overarching field of wildlife protection and conservation. This practice involves the treatment and hopeful release of wild animals affected by various ailments. With the continued expansion of and interest in the field, it could be assumed that wildlife rehabilitation is supported and funded by government bodies, but this is not the case. Because of the lack of funding and resources, many wildlife rehabilitation centers cannot achieve their full rehabilitative potential and expand their reach in the conservation world. Additionally, an absence of support leads critics to question the ethical standards of wildlife …

The migratory locust, scientifically known as Locusta migratoria (Linnaeus, 1758), is a captivating insect species that has drawn the interest of scientists, farmers, and the general public. Recognized for its notorious swarming behavior, this insect has the potential to cause extensive damage to crops, leading to agricultural plagues and food shortages. However, beyond its reputation as a pest, the migratory locust is a subject of scientific fascination due to its intricate life cycle, remarkable ability to undergo rapid and dramatic transformations, and its crucial role within the ecosystems it inhabits. This review delves into various facets of L. migratoria, including …

African lion (Panthera leo) being most attractive but vulnerable exhibit of zoos and safaris; need particular attention to breeding plans. At captive sites, lioness neglects newborns commonly; at that stage, hand rearing is preferred. This study will highlight the best practices for hand-rearing lion cubs, including knowledge of early medical issues along with their treatment during the first 4 months of growth. 34 lions (08Male: 17Females: 9Cubs) were housed on 15 acres during 2019-21 at Safari Zoo Lahore. A total of 04 lionesses were found entirely abandoned to 05 newborns (03 males & 02 females). The hand-rearing period …

Journal of Bioresource Management
In this research, we aimed to explore the insecticidal potential of Alternaria alternata, an endophytic fungus derived from the leaves of castor oil plant. To test its insecticidal efficacy, various doses of A. alternata mycoextract were administered to Locusta migratoria L. through both topical and oral pathways. The findings revealed that the insects displayed the highest susceptibility to a concentration of 2 g/L, leading to an impressive mortality rate of 87.5 % and 93.75 % for topical and oral administrations, in the same order. The extract displayed remarkable insecticidal properties, demonstrating LC50 values of 1.09 g/L for the topical …
