Biomechanics Of Mantis Prey Capture, Danielle S. Taylor
Biomechanics Of Mantis Prey Capture, Danielle S. Taylor
Honors Theses
Mantis species have a variety of different morphologies, so do the extreme forms of mantis limbs trade prey catching capability for camouflage? We hypothesize that some extreme forms of mantis limbs that are associated with cryptic species may be associated with a tradeoff of the capability of those limbs. Previous research has developed 2D morphologies of several hundred species of mantises. We are creating a 3D morphology by using micro dissection, micro CT imaging to construct our 3D biomechanical model. We found the attachment points of the ligaments and muscles from a Tenodera forearm and have constructed a 2D biomechanical …
Composition And Homology In The Taxonomic Classification Of Escherichia Coli, Tanya Irani
Composition And Homology In The Taxonomic Classification Of Escherichia Coli, Tanya Irani
Theses and Dissertations (Comprehensive)
As new techniques have been introduced, specifically the possibility of complete genome sequencing, better methods of defining bacterial species have also been proposed. One of the most recently proposed methods, using bioinformatic techniques, is to calculate the average nucleotide identity (ANI) between the homologous genome segments of different isolates. Another method for species discrimination that has been tested successfully is the similarity of DNA compositional signatures. However, in a recent update, DNA signatures split the available Escherichia coli complete genomes into three groups. To check if this result was consistent with such genomes belonging to different species, we tested methods …
Crispr Genetic Editing: Paths For Christian Acceptance And Analysis Of In Vivo And In Vitro Efficiency, Mandeep Sandhu
Crispr Genetic Editing: Paths For Christian Acceptance And Analysis Of In Vivo And In Vitro Efficiency, Mandeep Sandhu
Scripps Senior Theses
With advancements in CRISPR-cas9 broadening the potential paths for clinical usage of genetic editing, conversations about genetic editing have grown to outside simply scientific communities and into mainstream conversations. This study focuses specifically on Christian discourse of genetic editing and locates four major tensions for many Christians when they think about genetic editing: beginning of life, Creator-human relationship, imago Dei, and stewardship. With these major concerns in mind, I identify epigenetics, somatic cell genetic editing, and in vivo genetic editing research as important research paths to pursue as they can potentially produce techniques that more Christian individuals would feel comfortable …
Distribution And Stability Of The Lampricide 3-Trifluoromethyl-4-Nitrophenol (Tfm) In Non-Target Rainbow Trout (Oncorhynchus Mykiss) And White Sucker (Catostomus Commersonii), Darren Foubister
Theses and Dissertations (Comprehensive)
The lampricide 3-trifluoromethyl-4-nitrophenol (TFM) is applied to tributaries of the Great Lakes to control invasive sea lampreys (Petromyzon marinus). Although TFM is selectively toxic to larval sea lampreys, non-target mortality can occur during lampricide treatments. It is important to know whether or not TFM played a role in the death of these fishes, and the most direct means to do this is using forensic science principles. The objectives of this study were to: (i) determine the acute toxicity of TFM to the non-target fishes, rainbow trout (Oncorhynchus mykiss) and white sucker (Catostomus commersonii), and how the lampricide is …
"Mining" For A Reference Condition In Southern West Virginia Streams, Matthew Rouch
"Mining" For A Reference Condition In Southern West Virginia Streams, Matthew Rouch
Theses and Dissertations
Quarterly samples were used to estimate assemblage-level (all species combined) fish production within three minimally-impacted, southern West Virginia streams. The total annual fish production estimate was highest in Slaunch Fork (37.52 kg∙ha-1∙y-1), a tributary of the Tug Fork River, and lowest in Cabin Creek (10.59 kg∙ha-1∙y-1), a Guyandotte River tributary. Creek Chub Semotilus atromaculatus, Mottled Sculpin Cottus bairdii and Blacknose Dace Rhinicthys atratulus were the most abundant species among sites, accounting for >90% of all sampled individuals. Reference condition criteria were also selected and metrics calculated for each of the three …
Effects Of The Cle Elum Reservoir On The Ephemeroptera (Mayflies) Of The Cle Elum River, David Bruce Ainsworth
Effects Of The Cle Elum Reservoir On The Ephemeroptera (Mayflies) Of The Cle Elum River, David Bruce Ainsworth
All Master's Theses
The purpose of this study was to determine the physical and chemical effects of the Cle Elum Reservoir on the Cle Elum River and to evaluate these effects in respect to the Ephemeroptera of the Cle Elum River. Specific objectives were: (1) To determine the effects of the reservoir on current velocity, volume of flow, turbidity, and temperature. (2) To determine the effects of the reservoir on alkalinity, hardness, dissolved oxygen, and pH. (3) To evaluate the effects of the reservoir on the Ephemeroptera of the Cle Elum River.
