A Biochemical Approach To Determine The Target Site Recognition Mechanism Of The R2 Retrotransposable Elements
(Biology, 2011-07-14)Non-LTR Retrotransposons (NLRs) are selfish mobile genetic elements which parasitize the genomes of many organisms including humans. These elements transpose through an RNA intermediate and integrate directly into their ... -
Carbon, Nitrogen And Phosphorus Stoichiometry Of A Mixotrophic Protist
(Biology, 2008-08-08)The microbial loop is one of two major pathways in aquatic systems in which nutrient and energy flow from dissolved nutrients to higher trophic levels. Protozoan-bacteria predator-prey relationships lie at the base of ... -
The CCHC Motif In Non-LTR Retrotransposons Modulates RNA Associated Protein Conformational Changes
(Biology, 2014-03-10)Non-LTR retrotransposons encode a conserved cysteine histidine motif of undetermined function. The spacing of the cysteines and histidine residues in the motif is CX₃CX₇HX4C. The site specific non-LTR retrotransposon R2Bm ... -
Cellular Targets Involved In Reovirus-induced Oncolysis Of RAs-transformed Cells
(Biology, 2008-04-22)Reovirus is a ubiquitous virus with demonstrated oncolytic properties. In this study, we investigate the pathways which reovirus produces a lytic infection in SV-40 transformed WI-38 cells and the noncytocidal infection ... -
Characterization Of mocR, A GntR Transcriptional Regulator In Bradyrhizobium japonicum
(Biology, 2012-07-25)The GntR family is one of the most widely distributed and prolific groups of the helix-turn-helix (HTH) transcription factors. In particular, microorganisms that live in complex, fast-changing environments such as soil ... -
Comparing The Genome Expression Profiles Of Verrucomicrobium Sp. Strain Tav2 Cells Grown Under Two Different Oxygen Concentrations
(Biology, 2010-11-01)Termites are significantly different in their lifestyles and organization but most are linked by the common trait in degrading plant material, whether it is leaf litter, wood, soil or animal waste. They consume the ... -
Comparing The Melanin-concentrating Hormone -1 Receptor Expression In The Brains Of Mice And Rats
(Biology, 2007-09-17)The melanin-concentrating hormone (MCH) family of neuropeptides is believed to be important in controlling certain feeding behaviors. Recently, the distribution of melanin-concentrating-1 receptor (MCH-1R) in rat brains ... -
Determining the phylogeographic dynamics of the edge relationships between Aphonopelma hentzi (Girard) and its neighbors along the Colorado River Basin (Araneae, Mygalomorphae, Theraphosidae)
(Biology, 2009-09-16)Theraphosids, commonly known as “tarantulas”, are a group of large, hirsute spiders that have drawn relatively little interest in ecological, behavioral, or evolutionary research from biologists. The lack of research on ... -
Differentiation Of Gene Expression In Behaviorally Isolated Black And Brown Morphs Of Drosophila elegans
(Biology, 2007-09-17)Pre-zygotic isolation has been recognized as the primary form of incipient speciation, with behavioral isolation as one of its most significant manifestations. In spite of intensive research on behavioral isolation, its ... -
Does An Exotic Invasive Grass Facilitate The Invasion Of A Woody Species Into Remnant Prairies?: A Study of The Native, Prosopis glandulosa And the Alien, Sorghum halapense
(Biology, 2007-08-23)The native tree, Prosopis glandulosa, and the exotic grass, Sorghum halepense, have been invading native prairies in the Southwest U.S. since the 1800s. My objectives were to determine if S. halepense was driving shifts ... -
Ecomorphology Of The Mexican Fence Lizards Of The Sceloporus Formosus Group (Squamata: Phrynosomatidae)
(Biology, 2009-09-16)A central belief of ecomorphological studies is the link between morphology and performance, but, surprisingly few analyses demonstrate this relationship. Fence lizards of the genus Sceloporus offer a useful system for ... -
The Effects Of An Artifically Elevated Thermal Environment And Seasonal Acclimatization On The Thermal Tolerance Of The Western Mosquitofish, Gambusia affinis
(Biology, 2008-09-17)Gambusia affinis, the western mosquitofish, is a very hardy, live-bearing fish that has invaded freshwater habitats worldwide. The success of the western mosquitofishs' invasion is due to its reproductive capabilities and ... -
The Effects Of Mine Land Reclamation Of Herpetofaunal Communities
(Biology, 2012-07-25)Succession describes the process of community change over time after a disturbance. Understanding these processes allows ecological restoration projects to take advantage of natural community trajectories. Reclamation ... -
Effects Of Nutrient Limitation, Competitors And Grazers On The Abundance And Toxicity Of Laboratory Cultures Of P. parvum, a Harmful Alga
(Biology, 2008-08-08)P. parvum Carter is a haptophyte that occurs world wide in both fresh and brackish waters. Though P. parvum blooms occur world wide under a variety of environmental conditions, it occurs during the cooler months of the ... -
The Eggshell Structures Of Ringed Turtle - Doves (Streptopelia risoria)
(Biology, 2007-08-23)The avian egg provides nutrients and protects the growing embryo from physical and microbial harm. Structures fundamental to the protection are the membrane layers, which are tightly meshed networks of collagen fibers, ... -
Element Stoichiometry Of Ochromonas danica As A Function Of Growth Rate And Temperature
(Biology, 2010-03-03)The microbial loop stresses the importance of flagellated protozoa as predators of bacteria and regenerators of nutrients, the outcome of which affects higher trophic levels. The element stoichiometry of flagellates has ... -
Environmental Regulation Of Stomate-based Defense Against Bacterial Infection in Arabidopsis
(Biology, 2011-03-03)Stomata are natural openings in the plant epidermis responsible for gas (O2 and CO2) exchange between plant interior and environment. They are formed by a pair of guard cells, which are able to close the stomatal pore in ... -
Environmental, Genetic, And Maternal Effects On Life-history Traits Of The Striped Ground Cricket, Allonemobius socius
