Scorpiops Reini Sp. N. From Yunnan, China (Scorpiones: Scorpiopidae), Victoria Tang Dec 2024

Scorpiops Reini Sp. N. From Yunnan, China (Scorpiones: Scorpiopidae), Victoria Tang

Euscorpius

Scorpiops reini sp. n. is described from Yingjiang County (Dehong Prefecture, Yunnan Province) based on an adult pair. It can be readily discriminated from all of its congeneric geographic neighbors in Yunnan, namely S. jendeki Kovařík, 1994, S. shidian (Zhu et al., 2005), S. tongtongi Tang, 2022, and S. zhangshuyuani (Ythier, 2019). Within Yunnan, it resembles S. validus (Di et al., 2010) and S. yangi (Zhu et al., 2007) most, but can be identified by its large median ocelli (relative to the width of ocular subislet), pedipalp chelal finger morphology and pectinal tooth count. Beyond Yunnan, it shows the highest …


Star-Studded Stingers: Fluorescent Sensilla On The Scorpion Aculeus (Arachnida: Scorpiones), Graeme Lowe Dec 2024

Star-Studded Stingers: Fluorescent Sensilla On The Scorpion Aculeus (Arachnida: Scorpiones), Graeme Lowe

Euscorpius

The aculeus of the scorpion telson was studied by UV fluorescence microscopy. Numerous brightly fluorescent punctae were observed on the non-fluorescent distal aculeus, including the tip region. The punctae were identified as aculear sensilla coeloconica (ASC), and were connected to fluorescent canals running through the cuticle. ASC were present in both sexes, and in adults and immatures as early as the second juvenile instar, but were absent from the first instar. The distal aculeus was found to be encased in a thick, non-fluorescent dark exocuticle (DX), covering an underlying thin, fluorescent hyaline exocuticle (HX). Fluorescent ASC were recorded from 183 …

Study Of The Brain Anatomy Of Three Extinct Marsupials: Thylacinus Cynocephalus, Thylacoleo Carnifex, And Silvabestius Johnnilandi, Francisco Garcia Dec 2024

Study Of The Brain Anatomy Of Three Extinct Marsupials: Thylacinus Cynocephalus, Thylacoleo Carnifex, And Silvabestius Johnnilandi, Francisco Garcia

Honors Program Theses and Research Projects

Marsupials are pouched mammals that today are mainly found in Australasia and South America. Marsupials have proven to be quite intriguing to evolutionary biologists who note how some marsupials resemble placentals in anatomy due to convergent evolution, with both marsupials and placentals filling similar niches in their respective environments. As of today, studies interested in marsupial brain evolution have published descriptions of cranial endocasts for several species of marsupials, with the number of descriptions seeing a massive boost over the last 20 years with the arrival of CT imaging technology. However, no comprehensive study of brain evolution in marsupials has …


Finding Them Before They Find Us: Solving The Emerging Infectious Disease Crisis, Daniel R. Brooks Nov 2024

Finding Them Before They Find Us: Solving The Emerging Infectious Disease Crisis, Daniel R. Brooks

MANTER: Journal of Parasite Biodiversity

The human population grows daily, it’s on the move, and it’s carving a deep technological footprint on our planet. We alter landscapes and perturb ecosystems, inserting ourselves and other species into novel regions of the world, leading to potentially irreversible changes in the biosphere. This is not news. More than 75 years ago, Charles Elton, one of the founders of modern ecology, wrote, “We must make no mistake; we are seeing one of the greatest historical convulsions in the world’s fauna and flora.” We are also in the midst of a public health and epidemiological crisis. Climate change alters movements …

Georgia Journal of Science

The Hiwassee crayfish Cambarus hiwasseensis (CH) is an endemic species to the Hiwassee River watershed in north Georgia and western North Carolina that is sympatric with the more widespread Appalachian Brook crayfish Cambarus bartonii cavatus (CB). This was the first study to investigate CH habitat use, comparing CH habitat to CB habitat in Corn Creek, a small, second-order stream in the Hiwassee River watershed. From August to November 2016 and January to April 2018, 15 habitat parameters were measured for 154 1-m2 quadrants randomly sampled from an 800-m stream reach. Mann-Whitney U tests compared habitat parameters between present and …


Changes In Morphology, Phenology, Demography Of Several Avian Species Over 18 Years At A Restored Grassland, Ashley Mcmahon, Katie Stumpf, Charlie Muise Oct 2024

Changes In Morphology, Phenology, Demography Of Several Avian Species Over 18 Years At A Restored Grassland, Ashley Mcmahon, Katie Stumpf, Charlie Muise

Biology Theses

In response to a changing climate and habitat loss, avian species are displaying changes in body size, migration phenology, and demography. Species have often adhered to Allen’s and Bergmann’s rules, displaying increased wing length and decreased body mass, respectively, over time in response to higher temperatures. Additionally, climate change has resulted in earlier spring migration and depending on species, either earlier or later fall migration. Finally, species affected by habitat loss often display male-skewed sex ratios and juvenile skewed age ratios. Our goal was to determine how 1) body size, 2) migration phenology, and 3) demography have changed for grassland …

Cyprinella leptocheilus sp. nov., Siouan Thinlip Chub, is described as a new species that is endemic to Sand Hills and upper Coastal Plain streams in North Carolina and South Carolina. Recognized as an undescribed species since the early 1970s, this fish was known in the literature and in museum electronic databases as Hybopsis n. sp., H. sp. cf. zanema, Cyprinella n. sp., and C. sp. cf. zanema. Unofficially, it had gone by the common name Thinlip Chub. It was thought to be closely related to the two other barbeled Cyprinella species: Thicklip Chub, …


Clustered Setation On The Pedipalps Of Buthid Scorpions (Scorpiones: Buthidae), Graeme Lowe, Victoria Tang Oct 2024

Clustered Setation On The Pedipalps Of Buthid Scorpions (Scorpiones: Buthidae), Graeme Lowe, Victoria Tang

Euscorpius

Chaetotaxy of the external pedipalp femur and distal ventral pedipalp movable finger was studied in 120 species, 69 genera and 17 families of scorpions. Setation was generally denser in the ‘Buthus’ group, a major arid-adapted buthid lineage distributed across Palearctic deserts. On the external femur, macrosetae formed a prominent cluster, the ‘distal external macrosetal cluster’ (DEMC); on the distal ventral movable finger they formed a dense patch, the ‘distal ventral macrosetal cluster’ (DVMC). In other buthids and non-buthids, the DEMC and DVMC were mostly absent, except in a few arid-adapted genera. Relative setation densities of DEMC and DVMC in different …

In addition to morphology and hemispermatophore, we also present the information about the karyotype of Uroplectes ebogo sp. n. (2n=24).


Albinism In Olivierus Martensii (Karsch, 1879) (Scorpiones: Buthidae), Victoria Tang, Zhenbang Liu Oct 2024

Albinism In Olivierus Martensii (Karsch, 1879) (Scorpiones: Buthidae), Victoria Tang, Zhenbang Liu

Euscorpius

This is a formal case report for the albinism in Olivierus martensii (Karsch, 1879). Albino phenotype is compared with its normal counterpart in terms of their morphology and behavior by cursory experiments. The examined 7 albino individuals (5 of which were adults) were smaller and more slender than their normal counterparts. However, these quantitative differences were not statistically significant and should be treated with caution due to the low sample size. Their abilities to detect both white light and UV light or UV-excited fluorescence were not significantly undermined, although their tendency to ensure a clear vision through self-cleaning behavior appeared …


Effects Of Land-Use Types On Avian Functional Diversity In Kilimanjaro Region, Tanzania, Ava Joan Boettiger Oct 2024

Effects Of Land-Use Types On Avian Functional Diversity In Kilimanjaro Region, Tanzania, Ava Joan Boettiger

Tanzania: Wildlife Conservation and Political Ecology

This research examined avian abundance and functional diversity across four human land uses— monoculture, mixed farming, rural, and urban areas—in the Kilimanjaro Region of Northern Tanzania. Conducted in November 2024, the study aimed to assess how different land-use types influence avian composition and functional diversity. A quasi-experimental design was employed, using purposive sampling to select study sites and systematic random sampling point counts to observe bird species present in each land-use type. A literature review was also conducted to classify species into families and categorize them into functional feeding guilds: predators, insectivores, frugivores, granivores, and nectarivores. Statistical analyses, including ANOVA, …


Psychological And Social Well-Being Of Bony Fishes In Zoos And Aquariums, Ronald G. Oldfield, Patrick Bonano Oct 2024

Psychological And Social Well-Being Of Bony Fishes In Zoos And Aquariums, Ronald G. Oldfield, Patrick Bonano

Animal Sentience

Research on the behaviour of animals in zoos has been conducted for decades, and observations have provided information that has improved the psychological and social well-being of animals. However, research on fishes in zoos and aquariums seems to be lacking. Here, we assess the current state of research on fishes in zoos and aquariums by surveying the peer-reviewed literature. Our assessment differs from previous surveys in that we examine the taxonomic classes Chondrichthyes (sharks and rays) and Osteichthyes (bony fishes) separately. Our survey finds that bony fishes have been drastically underrepresented in zoo journals, more drastically than chondrichthyans, revealing an …

Herein, we report on the first record of the Diamond-backed Watersnake in Nebraska. On May 21, 2011, Daniel D. Fogell collected a juvenile Diamond-backed Watersnake in southeastern Richardson County representing the first occurrence of the species in the state, which is adjacent to Holt County, Missouri. In extreme southeastern Nebraska, the distribution of this …


Methodologies For Dry Fixation And Taxidermy Of Education-Oriented Scorpion Specimens, Victoria Tang Aug 2024

Methodologies For Dry Fixation And Taxidermy Of Education-Oriented Scorpion Specimens, Victoria Tang

Euscorpius

Scorpions hold a renowned status as iconic creatures across numerous cultures in the world. Traditionally preserved as desiccated specimens for educational purposes, they have been exhibited in museums and pedagogic collections, serving as concrete epistemological conduits for public education on biodiversity. However, these specimens frequently lack meticulous organization, potentially misrepresenting the animals’ ethological characteristics. This brief article aims to offer paradigmatic guidance for taxidermy of scorpions, ensuring a more accurate depiction of their in vivo habitus, achievable through the use of readily obtainable tools and undemanding techniques.

Impacts Of Invasive Carp And Their Population Dynamics On Fish Communities In The Missouri River, Joshua F. Kocik Aug 2024

Impacts Of Invasive Carp And Their Population Dynamics On Fish Communities In The Missouri River, Joshua F. Kocik

School of Natural Resources: Dissertations, Theses, and Student Research

Invasive Carp species: Silver Carp Hypophthalmichthys molitrix, Bighead Carp Hypophthalmichthys nobilis, Grass Carp Ctenopharyngodon idella, and Black Carp Mylopharyngodon piceus have both potential and realized abilities to negatively impact native species. Specifically, Bighead Carp and Silver Carp as filter feeders have been theorized to be detrimental not only to adult filter-feeding species, but to many fish which rely on plankton and algae in their early-life stages. The impact of Invasive Carp on the overall fish community remains underexplored. The fish communities below Gavins Point Dam (Invasive Carp present) and Fort Randall Dam (Invasive Carp absent) afford the …


Spatiotemporal Plasticity In Reproductive Readiness And Recruitment Of Ichthyoplankton Of Invasive Silver Carp Along A Western Invasion Front, Jessi L. Urichich Aug 2024

Spatiotemporal Plasticity In Reproductive Readiness And Recruitment Of Ichthyoplankton Of Invasive Silver Carp Along A Western Invasion Front, Jessi L. Urichich

School of Natural Resources: Dissertations, Theses, and Student Research

Individuals of invasive species at the edge of their invasion distribution may exhibit enhanced reproductive capacity and phenotypic plasticity leading to accelerated range expansion. Environmental conditions in highly fluctuating environments at distribution edges may either promote or hinder such reproductive readiness and phenotypic plasticity. Dynamic habitat conditions and periodic disturbances experienced in prairie streams, such as drought (e.g., low-flow, high water temperatures), may potentially reduce suitable spawning environments and ichthyoplankton recruitment of invasive Silver Carp, potentially slowing range expansion or enabling management strategies that reduce abundance in the absence of a reproducing population. Female Silver Carp batch fecundity, Gonadosomatic Index …


Avian Communities Monitored Along A Successional Chronosequence In Bottomland Hardwood Forests In The Lower Mississippi Alluvial Valley, Eamonn Alasdair Thurmond Aug 2024

Avian Communities Monitored Along A Successional Chronosequence In Bottomland Hardwood Forests In The Lower Mississippi Alluvial Valley, Eamonn Alasdair Thurmond

Electronic Theses and Dissertations

Bottomland hardwood forests in the Lower Mississippi Alluvial Valley have been extensively reduced due to agriculture conversion and altered hydrology. Remnant forests have undergone further degradation from sources such as a lack of forest management, invasive species, and reduced regeneration of oaks (Quercus spp.). Recent restoration efforts of bottomland hardwood forests have focused on implementing wildlife forestry practices that prioritize restoring wildlife habitat while retaining profitable timber harvests. In this study I surveyed bird communities in bottomland hardwood forests in the Lower Mississippi Alluvial Valley along a successional chronosequence. Birds were sampled using automated recording units over 10 days …


Phylogenetic And Biogeographic Patterns Of Devonian Proetid Trilobites, Katherine Jane Jordan Aug 2024

Phylogenetic And Biogeographic Patterns Of Devonian Proetid Trilobites, Katherine Jane Jordan

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Ecological disruption events such as mass extinctions can result in the permanent alteration in clades and ecosystems. A pivotal time of change during the history of life on Earth can be seen in the Devonian Period. During this time, major transitions in marine and terrestrial system resulted in a different world at the end of the period in comparison to the beginning. One such group most heavily impacted were trilobites. Trilobites were reduced to one order by the end of the Devonian: Proetida. My dissertation focuses on phylogenetic, biogeographic, and paleocommunity patterns of this group, known as the last of …


Postweaning Skull Growth In Living Didelphid Marsupials: The Case Of Gracilinanus Agilis And Cryptonanus Chacoensis, Iveth A. Villalobos Guerrero, Noé U. De La Sancha Jul 2024

Postweaning Skull Growth In Living Didelphid Marsupials: The Case Of Gracilinanus Agilis And Cryptonanus Chacoensis, Iveth A. Villalobos Guerrero, Noé U. De La Sancha

DePaul Discoveries

Ontogeny is described as the history of an organism through its lifetime including development, growth, and allometry. The ontogenetic approach in cranial dimensions has proved useful in interpreting evolutionary patterns. Among the largest Didelphidae family of Neotropical marsupials, the species of Gracilinanus agilis and Cryptonanus chacoensis are poorly known. In this study, we address three questions; Is there sexual dimorphism in these species? What is the pattern of allometry? Which allometric patterns best describe the patterns in the skull and mandible? We applied geometric morphometrics to describe and test these differences using MorphoJ. A discriminant function analysis was performed to …


Hybridization Between The Rare Gray-Headed Chickadee And The Abundant Boreal Chickadee In The Midst Of Shifting Climate, Matthew R. Armstrong Jul 2024

Hybridization Between The Rare Gray-Headed Chickadee And The Abundant Boreal Chickadee In The Midst Of Shifting Climate, Matthew R. Armstrong

School of Natural Resources: Dissertations, Theses, and Student Research

As species respond to changing climate, distributions and abundances may shift and alter species interactions. Hybridization, a relatively widespread phenomenon becoming more common with climate change, can have beneficial and detrimental effects on population growth rates and genetic integrity. Beneficial effects due to the introduction of advantageous alleles and increased genetic diversity may result from hybridization. Species may also accrue fitness costs associated with changing climates if mismatches occur between environmental variables and phenotypes. The gray-headed chickadee, Poecile cinctus lathami, is an extremely rare songbird that has experienced marked declines in recent decades within its restricted distribution in Alaska …

Reassignment Of Some Caryospora Species (Apicomplexa: Eimeriidae) To Eumonospora (Apicomplexa: Sarcocystidae) And A Summary, Donald W. Duszynski May 2024

Reassignment Of Some Caryospora Species (Apicomplexa: Eimeriidae) To Eumonospora (Apicomplexa: Sarcocystidae) And A Summary, Donald W. Duszynski

MANTER: Journal of Parasite Biodiversity

This review was crafted to clear up some of the current confusion regarding the correct taxonomic placement of those apicomplexan coccidians that produce unique monosporocystic octosporozoic (1 sporocyst with 8 sporozoites) oocysts during the sexual phase of their life history in vertebrate hosts. Currently, such oocysts have been placed in 1 of 4 genera, Avispora, Caryospora, Karyospora, or Eumonospora, 2 of which are no longer accepted or useful (Avispora and Karyospora). My review suggests that to present (2023) there are 62 valid Caryospora and 26 valid Eumonospora species. Caryospora species are recorded from a bird …
