The Herpetofauna Of The Virunga Mountains With Emphasis On Two Species of Albertine Rift Endemic Treefrogs Of The Genus Leptopelis.
(Biology, 2010-07-19)I present a short description of the biodiversity crisis, the Albertine Rift as a biodiversity hotspot, and a literature review of the taxonomy of the genus Leptopelis. I then present a list of the reptiles and anurans ... -
How Herbivores Affect Plant Growth, Community Structure And Litter Decomposition In Alaskan Tundra: Implications For Responses To Climate Change
(Biology, 2008-09-17)Increasing atmospheric carbon dioxide (CO2) concentrations have caused higher air temperatures in the Arctic. Because arctic organisms are temperature limited, warmer conditions lead to higher decomposition and nutrient ... -
How Soil Nutrient Availability Affects Plant Sexual Reproduction And Seedling Recruitment In Alaskan Dry Heath Tundra: Implications For Response To Climate Change
(Biology, 2009-09-16)The harsh growing conditions of the arctic biome, in particular low temperatures and soil nutrient availability, restrict the growth and reproduction of arctic plant species. Recent and ongoing changes in climate are ... -
Human Anatomy Lab Manual
(Mavs Open Press, 2018)This is a lab manual for a college-level human anatomy course. Mastery of anatomy requires a fair amount of memorization and recall skills. The activities in this manual encourage students to engage with new vocabulary in ... -
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 ... -
Identifying the Distinct Adaptive and Plastic Gene Expression Patterns and Microbial Indicators that Mediate Coral Disease Resistance
(2022-05-18)Infectious diseases are an increasing threat to coral reefs, resulting in altered community structure and hindering the functional contributions of disease susceptible species. While forecasting disease outbreaks based on ... -
Impacts Of Anthropogenic Disturbances And Drought On Breeding Bird Abundance And Diversity In The Rolling Plains Ecoregion Of Texas
(Biology, 2013-10-22)Bird species, especially grassland species have undergone widespread decline in arid grasslands due to anthropogenic disturbance such as different land use including cattle grazing and agriculture and addition of physical ... -
IMPACTS OF DAM REMOVAL ON CYANOBACTERIA BLOOMS AND ZOOPLANKTON COMMUNITY IN HYPEREUTROPHIC UPPER KLAMATH LAKE
(2023-08-14)The Chiloquin Dam was removed from the Sprague River in 2008 to restore the natural hydrology of Upper Klamath Lake (UKL), allow fish access to historical spawning grounds, and alleviate the effects of long-term eutrophication. ... -
Impacts of landscape and past climate on patterns of hybridization and genetic diversity in Plestiodon tetragrammus and P. multivirgatus
(2021-03-26)Past hybridization plays an important role in evolution of taxa. We use multiple phylogenetic approaches including single gene sequencing and high-through put sequencing to address the effects of past hybridization in the ... -
Insertion Mechanism of Long Interspersed Elements (LINEs) and the role of the Linker Domain
(2018-08-27)Long Interspersed Elements (LINEs), also known as non-Long Terminal Repeat (non-LTR) retrotransposons are major group of transposable elements ubiquitous in eukaryotic genomes and are known to altogether influence the ... -
Insights into the genomic and metabolic adaptations of Termite Associated Verrucomicrobia strains using functional and comparative genomics
(2016-12-16)The symbiotic gut organisms of termites play an important role in lignocellulose digestion and other related metabolic processes. Previous studies on Diplosphaera colitermitum TAV2, a Verrucomicrobium isolated from the ... -
Insights into the role and regulation of the mitochondrial unfolded protein response during pathogen infection
(2021-11-08)Mitochondria are essential cellular organelles known for their role in energy production, apoptosis, aging, calcium signaling and others. Due to their essential nature, mitochondria are often under attack by numerous ... -
Insights Into The Transmission Of Helitrons And Their Impact On The Genome Architecture Of Myotis Lucifugus, The Little Brown Bat
(Biology, 2011-03-03)Probably the most dynamic proportion of multicellular eukaryotic genomes is composed of teeming populations of parasitic mobile DNA, called transposable elements (TEs). Helitrons are rolling circle TEs that have a limited ... -
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 ... -
The Interplay Of Environmental Stressors On The Life History Traits In Daphnia lumholtzi
(Biology, 2014-12)In natural environments, organisms face multiple stressors that threaten their persistence. Aquatic organisms respond to a change in environmental conditions by adaptively modifying the expression of traits (i.e., ... -
Intra-specific Variation Across A Small Temperature Difference In The Spider Rabidosa rabida (Araneae: Lycosidae) From The Mountains In Arkansas
(Biology, 2011-07-14)Temperature affects all levels of biological organization and ultimately affects multiple aspects of ecological performance and fitness. Generalist arthropod predators are ectothermic and are strongly affected by temperature ... -
