Sex, War And Disease: The Effects Of Infection On Horn Size And Intra-sexual Competition In The Broad-horned Flour Beetle, Gnathocerus cornutus
(Biology, 2010-03-03)
Sexual selection is widely used to explain the evolution of mating systems where most often it is manifest as the competition among males for access to females. This competition takes the form of direct male-male interactions ...
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 ...
Integration Mechanism Of The Site Specific Non-LTR Retrotransposon, R2Bm
(Biology, 2010-07-19)
The focus of this thesis is the mechanistic study of non-LTR retrotransposon replication using the site specific transposon R2Bm. Non-LTR retrotransposons integrate into new chromosomal sites by copying their RNA back ...
Using Shewanella Baltica Ecotypes As A Model For Transcriptional Variation At The Population Level
(Biology, 2011-03-03)
Eukaryotic studies have shown considerable transcriptional variation among individuals of the same population. Owing to the cost of sequencing entire eukaryotic genomes, tested organisms were assumed to be genomically ...
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 ...
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 ...
Arctic Arthropod Communities In Habitats Of Differing Shrub Abundance
(Biology, 2012-07-25)
Recent global warming, which has been severe in the Arctic, has caused advancement in the timing of snowmelt and expansion of shrubs into open tundra. Such an altered climate may directly and indirectly (via effects on ...
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 ...
Addressing Prey Selection And Predator Fitness: Ingestion By, And Growth Of Ochromonas danica On Multiple Bacterial Prey
(Biology, 2012-04-11)
Nanoflagellates provide an important link in aquatic food webs by consuming bacterial biomass and subsequently providing nutrients to higher trophic levels by becoming prey themselves and regenerating nutrients consumed ...
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 ...
