Leveraging Mammal Mycophagy To Determine Environmental Drivers Of Truffle Diversity, Brittany Hartsock

Electronic Theses and Dissertations

Many mycorrhizal fungi are hypogeous (truffle-forming), producing underground fruiting bodies. Studying truffles is inherently challenging due to their hidden nature. However, mycophagous mammals provide a unique opportunity to study hypogeous fungi because they rely on truffles as a food source. Although several truffle species have recently been described in the southern Appalachian region, their fruiting patterns remain poorly understood. To address this, we quantified truffle richness and spore loads from 670 Peromyscus scat samples collected across 42 sites spanning an environmental gradient during 2024 in the Blue Ridge Mountains of East Tennessee. We found that truffle richness and spore abundance …

New Westernmost Record Of Jansen’S Goatfish, Parupeneus Jansenii (Mulli-Dae) From Indian Coastal Waters, Yosuva Mariasingarayan, Gopalan Mahadevan, Jeyapragash Danaraj, Mohanchander Ponnuvel

Makara Journal of Science

In July 2023, five individuals of Parupeneus jansenii were collected from the Parangipettai landing center, south-eastern India (Bay of Bengal). The standard length ranged from 140 to 150 mm, and two females and three males were recorded. This study confirms the first distributional record and the westernmost valid occurrence of this species in Indian coastal waters. P. jansenii significantly differs from P. heptacanthus in having fewer pectoral fin rays, more gill rakers on the upper limb, and 27 lateral line scales. Compared with P. angulatus, P. jansenii has a shallower body, a shallower caudal peduncle, a shorter snout, a …

Historical Chaos Among Tetrabothriideans (Eucestoda) Of Odontocetes (Artiodactyla)—Revising Generic Taxonomy And Species Diversity For Cestodes Among Oceanic Dolphins, Eric P. Hoberg, Kaylen Marie Soudachanh, Robert L. Rausch

MANTER: Journal of Parasite Biodiversity

Explorations over the past 150 years that have defined the diversity and structure of the tetrabothriidean cestode fauna among Odontocete cetaceans (Artiodactyla) are summarized and reviewed. Persistent errors in interpretation of comparative morphological characters, inconsistent taxonomic decisions, and an understanding of generic-level and species diversity are addressed. We outline a revision of the Tetrabothriidea, which now encompasses 8 genera. Prosthecocotyle is resurrected from synonymy with Tetrabothrius, and Cetaceobothridius n. gen is proposed. A clear basis is outlined for differentiation of generic and species diversity among Cetaceobothridius, Priapocephalus, Prosthecocotyle, Strobilocephalus, Tetrabothrius, and Trigonocotyle that constitute the tetrabothriidean fauna of odontocetes; species …

Pilot findings indicated improvements in resilience, self-efficacy, hopefulness, and connectedness to nature.

Long-Term Monitoring And Response Of Papaipema Sciata Bird (Lepidoptera: Noctuidae) To Prescribed Fire In Michigan (Usa), Gregory J. Norwood, Logan M. Rowe, Brett A. Degregorio, David L. Cuthrell, Aaron D. Meredith, Steven M. Gray

The Great Lakes Entomologist

The Culver’s root borer moth (Papaipema sciata) (Lepidoptera: Noctuidae) is a rare Noctuid that requires Culver’s root (Veronicastrum virginicum) to complete its lifecycle within remnant native grasslands and open woodlands in the midwest and northeast United States. We report on 26 years of monitoring this species’ colonization of Culver’s root stems at Algonac State Park (ASP) in Michigan, where prairies have been maintained by prescribed fire since 1990. P. sciata is considered fire sensitive because eggs spend the dormant season in the combustible prairie litter and duff near host plants. The objectives were to determine the …

Spider Biodiversity And Insecticide Sensitivity Across Active And Restored Cranberry Bogs On Nantucket, Tyler J. Kulak

Graduate Masters Theses

Spiders are one of the most diverse groups of organisms on the planet with over 53,000 species described as of 2026. They provide a suite of ecosystem services including their regulation of problematic pests in agricultural systems, appearing in high biomasses across a breadth of ecological niches. While beneficial as pest regulators, they are also susceptible to the same management techniques as pest organisms and are especially vulnerable to chemical control. Cranberry production in Massachusetts likely benefits from spider ecosystem services, but diversity research on spiders in these systems is limited. This study compares the diversity of spider populations from …

A New Species Of Liocheles Sundevall, 1833 (Scorpiones: Hormuridae) From The Western Himalayas, Virender К. Bhardwaj, Sunil Katal, H. T. Lalremsanga, Zeeshan A. Mirza

Euscorpius

Sampling in the Western Himalayas of India led to the discovery of a population of the genus Liocheles Sundevall, 1833, that differes from all Indian congeners. Molecular and morphological data confirmed the distinctiveness of the population, which is here described as a new species. The new species is morphologically similar to L. longimanus (Werner, 1939), from which it differs in the arrangement of trichobothria on external patella and structure of the hemispermatophore. A preliminary molecular phylogeny of the family Hormuridae based on the mitochondrial cytochrome oxidase I gene is presented.

New Locality Records And Future Habitat Suitability Of Sassanidotus Gracilis (Birula, 1900) (Scorpiones: Buthidae) In The Iran–Afghanistan–Pakistan Arid Belt, Ersen A. Yağmur, Kerim Çiçek, Homa Barati, Mohammad Moradi

Euscorpius

This study reports new locality records from Iran and a climate-based habitat suitability assessment for Sassanidotus gracilis (Birula, 1900) (Scorpiones: Buthidae) in the Iran–Afghanistan–Pakistan arid belt. We document new specimens from Sistan and Baluchestan Province, Iran, with an updated distribution map and illustrations, and we model the species' potential distribution across south-eastern Iran and adjacent parts of Afghanistan and Pakistan.

Habitat suitability was associated mainly with precipitation seasonality, precipitation of the wettest month, precipitation of the driest month, and slope. In an arid setting these rainfall variables are unlikely to indicate a need for moist habitat; they more plausibly track …

Comparing Non-Invasive Survey Methods For Southern Flying Squirrels (Glaucomys Volans) At The Western Edge Of Their Range, Jay E. Winfield, Jeremy A. White

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The southern flying squirrel (Glaucomys volans) is a threatened species in Nebraska that occurs along the Missouri River in the southeastern corner of the state. Recently, a population was discovered in the city of Lincoln, but it is unknown whether this population represents a natural range expansion from the Missouri River population or whether it is isolated and results from a human-assisted movement. A survey of southern flying squirrels in Nebraska is needed, but surveys of this elusive species are challenging. This study investigated and compared two noninvasive survey techniques for rapid detection of flying squirrels: acoustic detectors …

Snails In The Diet Of The Cutlip Minnow, Exoglossum Maxillingua, Tess A. Taloumis, Steven L. Powers

Southeastern Fishes Council Proceedings

The Cutlip Minnow, Exoglossum maxillingua, is an important stream fish native to the eastern United States. It has an unusual lower jaw morphology. Early hypotheses suggested the jaw morphology is an adaptation for feeding on snails. Despite the publication of numerous diet studies on this species, there is no documentation of snails as prey items. During recent snorkel observations in the Roanoke River, E. maxillingua was spotted carrying snails within their mouths, prompting further investigation. An in-depth temporal examination of the diet from 145 specimens of E. maxillingua across multiple sites was conducted to further investigate the diet of …

Re-Examining Endemic Smoky Dace As An Indicator Species In The Upper Little Tennessee River Index Of Biological Integrity, Tayton C. Alvis, William O. Mclarney, Radmila Petric, Jason P. Love

Southeastern Fishes Council Proceedings

Fish communities can be used to evaluate water quality and stream ecosystem health, helping resource managers understand the effects of anthropogenic disturbance. Fish species inform indexes of biological integrity through their ecological traits and tolerance to stressors (e.g. tolerant of disturbance, intolerant of disturbance), but these designations are difficult to determine without localized, species-specific information. The Upper Little Tennessee River watershed is subject to long-term aquatic biomonitoring, applying an index of biological integrity tailored to the region. In this index, the undescribed endemic Smoky Dace (Clinostomus sp.) is classified as intolerant based on a previous designation for the Rosyside Dace …

Exotic Two-Spined Trap-Jaw Ants (Odontomachus Haematodus) In Urban Parks Of Hattiesburg, Mississippi: Recommended Sampling Methods And Notes On Nesting Biology, Caroline M. Marley, Vinny Halsey, Lila Blackburn, Kayla D. Stan, Kaitlin M. Baudier

Midsouth Entomologist

The two-spined trap-jaw ant, Odontomachus haematodus (Linnaeus), is native to South America and was introduced to the United States via Mobile, Alabama in the mid-twentieth century. Misidentification as a native congener for several decades has inhibited the study of the ecology of O. haematodus in its introduced range within the Gulf Coastal Plain. We conducted a multimethod survey to: 1) assess the abundance of O. haematodus across urban parks in Hattiesburg, MS, the northernmost published record in this species’ exotic range, 2) establish which sampling methodologies are most effective for conducting urban surveys of O. haematodus, and 3) study …
