Scorpions Of Angola (Arachnida, Scorpiones). Part I. Family Buthidae, With Descriptions Of Two New Species., František Kovařík
Euscorpius
All scorpion species of the family Buthidae known from Angola are listed, with color photographs and maps of their distribution. Diagnosis of Babycurus ansorgei Hirst, 1911 is revised; its male is described for the first time. Babycurus crassicaudatus Roewer, 1952, is revalidated (it was erroneously synonymized with B. ansorgei, since the females of both species are morphologically almost identical). Uroplectes angolensis sp. n. and U. xavieri sp. n. are described from Angola. Validity of Uroplectes ngangelarum Monard, 1930 is confirmed as different from U. planimanus (Karsch, 1879); its lectotype is designated. Lectotype is also designated for Uroplectes planimanus …
Dimensional Welfare Beyond Pain: Extending The Precautionary Principle In Birch’S “The Edge Of Sentience”, Willa M. Lane, Nicola S. Clayton
Dimensional Welfare Beyond Pain: Extending The Precautionary Principle In Birch’S “The Edge Of Sentience”, Willa M. Lane, Nicola S. Clayton
Animal Sentience
Birch's (2024) The Edge of Sentience identifies sentience candidates primarily through the pain-focused LSE Criteria. Yet, as Birch himself notes in Proposal 17, sentience is not pain. We argue that statutory welfare protections must therefore reach beyond pain, and that the right tool for doing so is Birch et al.’s (2020) dimensionality framework, which characterises conscious experience across five domains. Used together, the LSE Criteria establish that welfare is at stake, while the dimensionality framework maps what is at stake beyond pain to provide a taxon-specific profile of where captivity impoverishes experience. We apply this approach to invertebrate welfare and …
History And Distribution Of Great-Tailed Grackles (Quiscalus Mexicanus) In Arkansas, R. Tumlison, V. Andersen
History And Distribution Of Great-Tailed Grackles (Quiscalus Mexicanus) In Arkansas, R. Tumlison, V. Andersen
Journal of the Arkansas Academy of Science
Great-tailed Grackles (Quiscalus mexicanus) were reported first in southwestern Arkansas in 1969, were nesting there in 1977, and established a resident population by 1980. Nesting was reported in far northwestern Arkansas in 1986. Presently, the species is known from 44 of Arkansas’s 75 counties, those mostly in the western and central counties. Most individuals appear to be migratory, with most reports occurring in April and May. However, breeding and now resident populations have been reported in the southwestern, northwestern, and central counties, particularly in urban areas. Birds are very commonly reported to forage at fast-food establishments and truck …

Makara Journal of Science
Anthropogenic impacts within the watershed threaten the survival of sheat catfish. Therefore, species of the genera Ompok and Kryptopterus should be conserved and domesticated to ensure their long-term persistence. Moreover, the accurate documentation of the existence and taxonomic validity of Ompok and Kryptopterus species is crucial. Accordingly, this study aims to assess the species diversity of the genera Ompok and Kryptopterus in the Mahakam River, East Kalimantan, Indonesia. The study was conducted between June and December 2014, with an update in August 2024. Fish samples were collected from the upstream and middle reaches of the Mahakam River. A total of …
Natural Behavior Vs. Subjective Experience In Fish Welfare Assessments, Ronald G. Oldfield
Natural Behavior Vs. Subjective Experience In Fish Welfare Assessments, Ronald G. Oldfield
Animal Sentience
Several commentaries on the Oldfield & Bonano (2024) target article proposed that natural behavior should play a larger role in assessing the welfare of fishes in zoos and aquariums. However, the natural-behavior concept of animal welfare has been widely criticized because natural behaviors do not necessarily improve welfare, and unnatural behaviors do not necessarily reduce it. I review the three major concepts of animal welfare — physical health, natural behavior, and affect/feelings — and argue that behavior patterns, whether natural or otherwise, should be evaluated according to their effects on health and subjective experience. Using the affect/feelings concept and the …
The Helminthic Status Of Selected Tanzanian Subterranean Rodents, The Root-Rats (Spalacidae: Tachyoryctes Splendens) And Emini Silvery Mole-Rats (Bathyergidae: Heliophobius Argenteocinereus Emini), Jestina V. Katandukila
The Helminthic Status Of Selected Tanzanian Subterranean Rodents, The Root-Rats (Spalacidae: Tachyoryctes Splendens) And Emini Silvery Mole-Rats (Bathyergidae: Heliophobius Argenteocinereus Emini), Jestina V. Katandukila
Tanzania Journal of Science
Root-rats (Tachyoryctes splendens) and emini silvery mole-rats (Heliophobius argenteocinereus emini) are common subterranean rodents that are essential component of the ecosystem. They serve as prey for small to medium-sized carnivores and birds of prey but their role as hosts to parasites is limited. The present study, explored the Gastrointestinal Tract (GIT) contents of 40 rodents (20 T. splendens and 20 H. a. emini, respectively) to acquire information on parasites diversity of these mammals. The GIT contents from subterranean rodents in a sex ratio of 1:1 were examined under a compound microscope to isolate helminths. The isolated helminths belonged to the …
Effect Of Temperature On The Defensive And Predatory Behavior Of The Scorpion Hadrurus Obscurus (Scorpiones: Hadruridae), Zia Nisani, Megan Bennett, Audrey Enriquez, Mel Iniquez, Emilia Martinez Rios, Brooklyn Stone
Effect Of Temperature On The Defensive And Predatory Behavior Of The Scorpion Hadrurus Obscurus (Scorpiones: Hadruridae), Zia Nisani, Megan Bennett, Audrey Enriquez, Mel Iniquez, Emilia Martinez Rios, Brooklyn Stone
Euscorpius
Scorpions employ their stinging mechanism both for defense and predation, and being ectothermic, temperature influences their physiology and behavior. As such, we hypothesized that temperature both affects defensive stinging and prey-capture behavior in scorpions. We tested the effects of body temperature on these behaviors in the desert hairy scorpion, Hadrurus obscurus Williams, 1970. In the first experiment, scorpions were placed in temperature-controlled chambers with either high (26-28°C) or low (21- 22°C) temperatures and probed to elicit a defensive sting. We recorded the reaction time and the number of probes needed to elicit a sting. In the second experiment, we observed …

Compsobuthus Hadeki Sp. N. From Iraq (Scorpiones: Buthidae), František Kovařík, František Šťáhlavský
Euscorpius
A new species, Compsobuthus hadeki sp. n. from Iraq is described and fully complemented with color photographs and compared with morphologically the most similar species, C. matthiesseni (Birula, 1905). The two species can be unequivocally separated by the following morphological features: in C. hadeki sp. n., movable finger of pedipalp bears 9 rows of granules; telson with aculeus shorter than vesicle, and metasoma III with 10 carinae. Cytogenetic analysis was performed, revealing a diploid chromosome count of 22 in C. hadeki sp. n.

Patterns And Drivers Of Cladocera Community Structure In The Black Sea, Elena Bisinicu, Luminita Lazar
Patterns And Drivers Of Cladocera Community Structure In The Black Sea, Elena Bisinicu, Luminita Lazar
Turkish Journal of Zoology
Cladoceran community dynamics were examined in the Romanian sector of the Black Sea during the warm seasons of 2013– 2020, using Marine Reporting Units (MRUs) to evaluate spatial heterogeneity across transitional, coastal, and marine waters. Analyses of density, biomass, mean individual biomass (MIB), and species composition revealed interannual fluctuations superimposed on strong nearshore–offshore gradients, with higher values in transitional and coastal MRUs. The assemblage was consistently dominated by Pleopis polyphemoides and Penilia avirostris, which together accounted for most of the total abundance and biomass. Multivariate analysis identified significant differences in taxonomic composition across MRUs and years, while correlation analyses highlighted …
Endemism Patterns Of Leaf Beetles (Coleoptera: Chrysomelidae) In Türkiye, İsmai̇l Şen, Ali̇ Gök
Endemism Patterns Of Leaf Beetles (Coleoptera: Chrysomelidae) In Türkiye, İsmai̇l Şen, Ali̇ Gök
Turkish Journal of Zoology
In this study, the distribution of endemic leaf beetles in Türkiye was analyzed holistically at the provincial scale using species richness (ENR), corrected weighted endemism (CWE), and range-restricted endemism (RRE) indices. A total of 95 endemic taxa were found in Türkiye and these taxa exhibited significant spatial heterogeneity in terms of richness and extent of distribution. The Western and Central Taurus Mountains and the Eastern Black Sea Region were found to be the main centers of endemism, with high densities of narrowly distributed and geographically restricted species. These patterns clearly demonstrate that key biogeographic factors, such as steep elevation gradients, …

The Effect Of Spatial Scale Of Habitat On Abundance Of Roe Deer (Capreolus Pygargus) And Water Deer (Hydropotes Inermis Argyropus) During Summer In South Korea, Naeyoung Kim, Hyejin Kim, Hyoun-Gi Cha, Hyun-Su Hwang
Turkish Journal of Zoology
Understanding species-specific habitat preferences provides essential ecological information about interactions among habitat components. In South Korea, roe deer (Capreolus pygargus) and water deer (Hydropotes inermis argyropus) are the dominant large herbivorous mammals of the family Cervidae. The increasing populations of these species have led to ecological and economic challenges. Therefore, we investigated the effects of spatial scale characteristics on the habitat preferences of roe deer and water deer. From June to August each year between 2021 and 2023, we calculated the relative abundance index (RAI) using camera-trap data and analyzed patch characteristics in the study area using remote sensing techniques, …

Turkish Journal of Zoology
Lissachatina fulica mucin can be used as a nutraceutical agent depending on the quality of their feed. Polystyrene (PS) waste harms soil and plants consumed by snails, potentially affecting the quality of mucin production. This study investigated the impact of PS on growth and mucus-producing cell characteristics as well as the network pharmacology of mucin protein components. Fifty 5–6 cm L. fulica snails (20–24 g) were fed organic waste (OW) and organic waste with PS (OWPS). After 28 days of ad libitum access to food, the snails’ mucus, meat, and shells were collected and weighed. Tissue samples from the anterior …

Euscorpius
This study re-examines the holotype of “Tityus” tenuimanus Banks, 1910, previously synonymized with Buthus atlantis Pocock, 1889 by Lourenço & Francke (1984). Our results indicate that the specimen is a misidentified representative of Leiurus Ehrenberg, 1828, as it exhibits the diagnostic characters of this genus: the central lateral and posterior median carinae of the carapace fused into a lyre-shaped configuration, and tergites I–II bearing five granular carinae (a character absent in the genus Buthus Leach, 1815). Moreover, the holotype lacks one of the most distinctive characters of the genus Tityus Koch, 1836, namely the presence of a subaculear tubercle. The …

Scorpions In Brazilian Caves And Other Subterranean Habitats, Jonas E. Gallão, Bruno D, Lenhare, Misael Oliveira-Neto, Maria E. Bichuette
Euscorpius
Arachnids have successfully colonized subterranean environments. Compared to spiders, harvestmen, and pseudoscorpions, scorpions have a moderate number of subterranean species, including troglophiles and troglobites. Among the four families and 184 species and three subspecies of scorpions found in Brazil, three families and at least 33 species and one subspecies have been documented in subterranean habitats. This study presents a faunistic list of scorpion occurrences in caves and other types of subterranean habitats in Brazil, along with distribution maps and an attempt to classify species based on their use of and dependence on subterranean environments.

Paqr7 and paqr8 are genes encoding membrane progestin receptor αand β (mPRα and mPRβ, respectively), which are currently classified as members of the progestin and adipoQ receptor (PAQR) family. For mPRα, the first identified mPR gene, there are two paralogs in zebrafish, paqr7a and paqr7b. In order to elucidate the physiological functions of the mPR subtypes, we created gene knockout (KO) fish by editing seven paqr genes in zebrafish and analyzing their phenotypes. The null-mutant strains of paqr7a, paqr7b, and paqr8 presented no significant abnormalities in reproductive functions. Thus, we generated a triple-gene knockout (TKO) strain of …

The Beat Behind The Bark: Investigating The Effects Of Music Tempo On Canine Physiological And Psychological States, Marley Lanier
Poster Presentations
Music is a universal component of human culture that has been demonstrated influencing emotional, cognitive, and physiological responses, specifically heart rate and hormonal responses (Mehr et al., 2019; Trappe, 2012). Recently, this research has expended to explore how music may affect non-human animals, particularly dogs, due to their roles as therapy animals, service animals, and human companions (Lindig et al., 2020; Gee et al., 2021). Being able to understand how music influences canine stress and relaxation hold important applications in environments such as shelters, veterinary clinics, and at home. One important feature of music is tempo, or beats per minute …

The Hitchhiker's Guide To The Host: Fleas And The History Of Pikas In North America, Josh Pletcher
The Hitchhiker's Guide To The Host: Fleas And The History Of Pikas In North America, Josh Pletcher
All NMU Master's Theses
Parasite phylogenetics can offer windows into the cryptic evolutionary history of hosts, often highlighting events that are not recorded by the phylogenetics of the host. Pikas (small lagomorphs) host a diverse parasite community comprising endoparasites (e.g., coccidians, nematodes, and cestodes) and ectoparasites (e.g., fleas and mites). Phylogenetic analysis of pika endoparasites has revealed pikas evolved in Asia and colonized North America in two waves, and that contact between these two pika lineages allowed parasites to be transferred from one lineage to another and to survive the extinction of their original host. To uncover these cryptic histories, understanding the biogeography of …
Ontogeny And The Effects Of Perinatal Stress In The First Immature Skeleton Of Teleoceras Aepysoma (Perissodactyla, Rhinocerotidae), Joe Gajewski
Electronic Theses and Dissertations
Recovery of an immature fossil rhinoceros (Teleoceras aepysoma) skeleton (ETMNH 32999) from the Gray Fossil Site in Tennessee offers the first insights into the ontogeny of the species. ETMNH 32999 is interpreted to be a subadult male in an age class equivalent to ~17-20% of potential lifespan. Comparative analyses support the hypothesis that subadults of related taxa are typically ~91% of average adult size in most dimensions. However, certain cranial dimensions are substantially lower than expected in ETMNH 32999, averaging only ~74% of the average conspecific adult. Such departure from typical growth rates is suggested to be attributable …

2nd Place Research Paper: Shaping The Ape: Storytelling, Cultural Reflection, And Boundary Negotiation In Human-Ape Zoo Encounters, Abigail Bond Halling
Kevin and Tam Ross Undergraduate Research Prize
The typical Western zoo functions as a unique environment in which animals are frequently positioned as subjects of education and entertainment through the medium of storytelling. In this sense, the zoological institution can also be read as an extension of popular Western constructions surrounding nonhuman animals, particularly those who are symbolically charged characters in our collective imaginary– the great apes. Given the morphological, behavioral, and psychological similarities between humans and other great apes (chimpanzees, gorillas, and orangutans), nonhuman great ape enclosures at the Western zoo become spaces where humans are most radically confronted with navigating the boundaries of the “human-animal …

Feeding Ecology In Coastal Systems, Randi L. Cannon
Graduate Theses and Dissertations (2019 - present)
Oysters (Crassostrea virginica) are critical foundation species in estuaries, providing numerous ecological and economic benefits. However, oyster populations have diminished worldwide. Effective oyster restoration and aquaculture require a mechanistic understanding of the physiological and environmental factors that govern oyster feeding, growth, and resilience under changing coastal conditions. We investigated how oyster ploidy and environmental conditions influenced oyster feeding and investigated how changes in abiotic conditions affected behavioral performance of oyster drills (Stramonita spp.), a key oyster predator. To better understand feeding responses and behaviors of both predator and prey we 1) used in-situ filter feeding assays to determine if feeding …

Aggression And Fish Welfare: Challenges And Opportunities, Christine M. Soper, Peter D. Dijkstra
Animal Sentience
Oldfield & Bonano’s (2024) [O&B] target article discusses the wellbeing and sociality of bony fishes. Many fish species, such as cichlids, are not only social but territorial. Aggression is normal, but territorial aggression in a captive environment can have a negative impact on welfare. Aggression-related injuries and deaths are prevalent in pet stores as well as research settings. We discuss the need to develop effective methods to minimize the negative consequences of aggression.

Exploring Decision-Making In Caenorhabditis Elegans: Navigating Dichotomous Envrionmental Cues, Hunarmeet K. Gill
Caroliniana Undergraduate Research Journal
All living organisms thrive off the survival choices they make and the factors they prioritize, but the mechanisms guiding these choices remain unclear. This study investigates decision-making in Caenorhabditis elegans, aiming to understand how they navigate dichotomous environments that contain both attractive and aversive cues. Despite possessing a simple nervous system, C. elegans express behaviors indicating a level of advanced sensory-processing abilities, making them ideal models for studying decision-making processes. The experiment consisted of five separate petri-dish tests, each with three sections: side A and side B (containing natural or UV light and/or E.coli or ethanol), and a neutral …

Hot Cities, Cool Lizards: Do College Campuses Create Urban Oases For Wildlife?, Ethan Heck, Javier Monzon Phd
Seaver College Research And Scholarly Achievement Symposium
Urban wildlife may experience stress due to the Urban Heat Island Effect. On the other hand, urban wildlife may experience relief, especially in arid ecosystems, due to the Urban Oasis Effect. The objective of this study was to test whether college campuses in southern California act as heat islands or oases for wildlife. We analyzed how temperature and water availability of microhabitats relate to the physiology of a widespread and common cold-blooded animal, the Western Fence Lizard (Sceloporus occidentalis). We logged environmental conditions in lizard hotspots at 11 university campuses across southern California and measured the hydration of lizards at …
