Distribution, Habitat, And Fish Assemblages Associated With The Rocky Shriner In Arkansas, Savannah L. Wise
ATU Theses and Dissertations 2021 - Present
The Rocky Shiner (Notropis suttkusi) is a minnow species endemic to the Red River and its tributaries in southern Arkansas and Oklahoma. This species is petitioned for listing under the Endangered Species Act and is a species of greatest conservation need (SGCN) in Arkansas. However, there is little information for the species’ distribution, habitat use, and ecological niche, especially within the Arkansas portion of its range. Because of this data gap, my study provides an updated description of its distribution and habitat associations using conditional occupancy modeling and explores patterns of species co-occurrence within the community. I sampled …
Clethra Alnifolia: A Fact Sheet For Seed Transfer Considerations, Taylor Houggy
Clethra Alnifolia: A Fact Sheet For Seed Transfer Considerations, Taylor Houggy
Plant Science Articles
Clethra alnifolia is a highly prized fragrant deciduous shrub, often found in many home gardens across Eastern North America. Despite its popularity in the landscape industry, there is little research comparing C. alnifolia's natural habits in the wild to its habits as a landscaped cultivar. Information such as flowering phenology, genetic diversity, and growth habits have the potential to change considerably depending on C. alnifolia's location. Because of this, it is important that landscape growers as well as forest conservationists have access to ecological fact sheets in order to make informed decisions when transferring seed to different areas. In this …

Assessing the spatial distribution of invasive species is a critical component for establishing baselines to examine the rate of spread, documenting key areas where negative impacts on ecosystems can be mitigated, and developing sustainable management strategies. Callery pear (Pyrus calleryana Decne.; PC) is a rapidly spreading invasive woody plant species in the eastern United States (U.S.). The incursion of these wild-type trees into urban, peri-urban, and rural landscapes, which have escaped from transplanted clonal cultivars, poses complex management challenges for land managers and hampers ecosystem function by competing with native plant species and altering the forest environment. We integrated …

Monitoring The Seasonal Presence Of The Blue Shiner, Cyprinella Caerulea, In Little River Canyon National Preserve Using Environmental Dna, Deanna Meadows
Theses
The study of environmental DNA (eDNA) has provided researchers with a more accessible and sensitive way to identify the presence of specific species compared to traditional monitoring methods. eDNA enables species detection by analyzing environmental samples such as water or soil, which contain genetic material shed by organisms in a given area. Research indicates that eDNA techniques have become a valuable method for monitoring threatened and invasive species, proving particularly reliable for detecting aquatic species compared to traditional techniques. Quantitative PCR (qPCR) has been used in numerous eDNA studies, as it provides for greater accuracy than conventional PCR. Cyprinella …

Exploring Long-Term Patterns: Black Bass Tournament Fishery And Population Trends In West Virginia's Navigable Rivers, Alex J. Benecke
Graduate Theses, Dissertations, and Problem Reports (ETD)
Black bass Micropterus spp. are popular sport fish in West Virginia’s navigable rivers. In recent years, anglers have expressed concerns about a potential decline in fishery quality. To investigate these claims, we evaluated whether fishery quality has declined compared to earlier periods and whether population trends correspond to angler catch rates. Specifically, we aimed to (1) examine changes in species catch over time and during key periods, such as tournament and spawning seasons; (2) describe the distribution of black bass species across pools and habitat types; and (3) assess the outcomes of previous stocking efforts. To address these objectives, we …

Green spaces represent the only natural areas in several cities around the world, providing good shelters for the local fauna. Based on this premise, many ecological studies have been conducted focused on these areas. Most of these works are about insects, particularly butterflies and beetles. Our study is centered on a different group: green lacewings (Neuroptera: Chrysopidae). These insects exhibit a similar feeding behavior to some other groups, such as beetles. We estimated diversity, richness, distribution, abundance and similarity employing two methods: sweep netting and suction trapping. Also, oviposition hosts were identified in 20 different green spaces. Approximately 740 specimens …

The Status Of Invasive Dusky Slug (Arion) Species In The Upper Great Lakes: A Molecular Approach, Olivia W. Hall
The Status Of Invasive Dusky Slug (Arion) Species In The Upper Great Lakes: A Molecular Approach, Olivia W. Hall
All NMU Master's Theses
I update the distribution of two cryptic slug species, Arion fuscus and Arion subfuscus, in the Upper Great Lakes of the United States using molecular identification methods. Arion fuscus has not previously been reported in the literature in this region, and Arion subfuscus has previously been reported as abundant. However, all previous distribution studies were determined using visual identification tools, which can result in misidentification between cryptic species. To molecularly re-examine these distribution maps, I used a mitochondrial ribosomal subunit 16S PCR amplification and subsequent SSpI and MfeI restriction enzyme digest to identify slug specimens. I collected slugs in …

Weddell seals (Leptonychotes weddellii) are important predators in the Southern Ocean and are among the best-studied pinnipeds on Earth, yet much still needs to be learned about their year-round movements and foraging behaviour. Using biologgers, we tagged 62 post-moult Weddell seals in McMurdo Sound and vicinity between 2010 and 2012. Generalized additive mixed models were used to (i) explain and predict the probability of seal presence and foraging behaviour from eight environmental variables, and (ii) examine foraging behaviour in relation to dive metrics. Foraging probability was highest in winter and lowest in summer, and foraging occurred mostly in …
