Identifying Individual Eurasian Otters (Lutra lutra) Based On Measurements Of Their Footprints Standardization Of The Method And Its Potential For Censusing And Monitoring Wild Otter Populations
(Biology, 2007-08-23)
A method for identifying individual Eurasian otters (Lutra lutra L.) from measurements of their footprints was first tested by performing experiments with captive animals. Digital photographs were taken of imprints in mud ...
A Study Of Factors Affecting Scale Roughness In The Western Diamondback Rattlesnake (Crotalus atrox)
(Biology, 2007-08-23)
Reptilian scales are very complex with patterns across their surface like a human fingerprint. These patterns are species specific, but there has been no way to quantify differences. A new technique using the confocal ...
Use Of Temperature Sensitive Mutants To Map Reovirus Induced Oncolysis
(Biology, 2007-08-23)
Reovirus is known to establish persistent infections in normal cells while selectively destroying transformed cells. Individual viruses from each of the ten groups of Reovirus is known to establish persistent infections ...
Proteasomal Gene Duplications And Recruitment Of Testis Specific Expression In Drosophila
(Biology, 2008-09-17)
Proteasome is a large multisubunit complex that degrades ubiquitinated proteins in a highly regulated manner in all eukaryotes. Two subcompartments of this subunit are the 19Scap and the 20S core particle with 19S acting ...
Study Of The Expression Pattern Of A Possible Pseudogene And A Functional Retrogene In Drosophila
(Biology, 2007-08-23)
Gene duplication occurs when a mutation leads to the copying of a region of DNA that contains a functional gene. After duplication, there will be two copies of the gene in the genome. Gene duplication can have deleterious ...
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 ...
Monte Carlo Analysis Of Refuge Site Selection: Statistical Properties And An Empirical Example
(Biology, 2007-10-08)
The Monte Carlo method can be a useful technique providing information on central tendencies and tolerance for selection data. There are many statistical hypothesis tests that are employed in selection studies, but most ...
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 ...
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 ...
