Mechanics of Righting Behavior in the Tarantula (Theraphosidae)
… taxa, and is largely based on body morphology. Tarantula righting behavior is not only needed in critical situations (falling and landing upside down), but is necessary after molting, when the tarantula must intentionally turn itself upside down in order to shed the old cuticle. In order to …

Hv1 novel peptide inhibitor extracted from tarantula venom
… between GsAF-I, a peptide from the venom of the tarantula Grammostola rosea, and human voltage-gated proton (Hv1) channels, critical in pH regulation and cellular signaling. Utilizing patch clamp techniques on genetically modified Chinese Hamster Ovary cells expressing human Hv1, the study …

Looking for love on a chilly night: The Colorado brown tarantula mating season
… hentzi is the most widespread and abundant tarantula species in the United States. While a distinct mating season is observed, it has not been well studied and the environmental drivers for the mating season are unknown. By conducting daily surveys on a peripheral population within Southeast …

Behavioral ecology of the Colorado brown tarantula (Aphonopelma hentzi): Activities displayed around the burrow through juvenile group dispersal
… life history strategy of the Colorado brown tarantula (Aphonopelma hentzi) typically includes males spatially scattering in search for a female mate in the fall, followed by female attendance of fertilized eggs the following summer. Here, I highlighted aspects associated with this female …

The effect of prey availability on metabolism and activity in the tarantula <i>phormictopus cancerides</i> (araneae: theraphosidae)
… metabolic rates (RMR) and foraging activities in tarantulas (<em>Phormictopus cancerides</em>). Juvenile tarantulas were separated into two feeding groups and fed once either every 5 or 30 days. Monthly feeding trials were preceded by RMR measurements. During feeding trials I compared differences …

Assessing pace-of-life: Comparing metabolism and behavior in tarantulas
… invertebrate groups. In this study I used five tarantula species to assess if they follow the predictions of PoLS. I compared individual species as well as Old- and New-World lineages and solitary and sub-social species. I predicted that Old- World and sub-social species would have higher …

A Bayesian network framework for fusing spectrum-based fault localization and forward slicing
… on spectrum analysis (SBFL), such as Ochiai, Tarantula, D*, and Barinel, have achieved state-of-the-art performance in many benchmarks, yet their effectiveness can degrade in complex, multi-fault programs where coverage information alone is insufficient. Program slicing, in contrast, provides …

Vocational curriculums and best practices for emotionally disturbed students
<p>Traditional education routes are not always an appropriate fit for students, particularly those with Emotional/Behavioral Disabilities (EBD). With limited academic, social, and self-determination skills, often times upon leaving high school these individuals do not attend or are not successful …

Improving the Sustainability of Performance-Based Concrete Overlay Mix Design made with Rounded Aggregate
… void ratio method, combining the Power 45 and Tarantula curves to improve particle packing and concrete cohesiveness. Concrete mixtures were designed with three types of cement, Type I/II, Type IL, and calcium sulfoaluminate cement with polymer (CSAP), and evaluated at two water-to-cement …

Studying the impact of early test termination due to assertion failure on code coverage and spectrum-based fault localization
… in terms of Mean First Rank (MFR) for Ochiai and Tarantula, respectively. We also provide actionable suggestions to prevent early test termination, and approaches to mitigate early test termination if it already exists in their project.

The Structural and Functional Analysis of a Voltage-Dependent Potassium Channel
… as demonstrated by KvAP's sensitivity to tarantula toxins that bind a receptor on its voltage sensor—toxins that evolved to inhibit the voltage-dependent channels of the eukaryotic prey of these spiders. I present low-resolution crystal structure of the KvAP channel and compare it with a …

TRP channels and a dextran sulfate activated rise in intracellular Ca2+ and Na+ in a subpopulation of double positive thymocytes
… disruption of F-actin polymerization and the tarantula toxin GsMTx4 abolished the rises, suggestive that mechanosensitive stimulation is involved. All these observations indicate that a non-specific cation channel of the TRP family could be involved. In Chapter 4, commencing with a list of 14 …

Interactions of insecticidal spider peptide neurotoxins with insect voltage- and neurotransmitter-gated ion channels
… homologous peptides isolated from the African tarantula, Eucratoscelus longiceps and ƙ-HXTX-Hv1c is the prototypic member of a family of insect-selective neurotoxins isolated from the venom of the Blue Mountains funnel-web spider, Hadronyche versuta. This thesis describes the characterisation …
