Assessing Tropical Mammal Diversity And Distribution Using Noninvasive Methods, Tiff L. Degroot
Assessing Tropical Mammal Diversity And Distribution Using Noninvasive Methods, Tiff L. Degroot
Dissertations, Master's Theses and Master's Reports
Central African tropical forests are rich in biodiversity and home to some of Earth’s most threatened mammals. However, mammals in the region are under increasing threat from habitat loss and degradation, coupled with an increased demand for wild meat. To conserve mammals, wildlife managers and community-led conservation efforts must understand the distribution and diversity of mammal communities. However, funding and logistical challenges make contemporary survey methods, e.g. ground surveys, difficult and expensive. Noninvasive methods allow efficient mammal diversity surveys with minimal field effort. Here, we use camera trapping and invertebrate-derived environmental DNA (“iDNA”) to assess mammal diversity and distribution in …
Characterizing Drought Adaptations, Phenotypic Plasticity, And Fixed Gene Expression Patterns Within Quercus, James K. Rauschendorfer
Characterizing Drought Adaptations, Phenotypic Plasticity, And Fixed Gene Expression Patterns Within Quercus, James K. Rauschendorfer
Dissertations, Master's Theses and Master's Reports
This dissertation was written on topics related to the genus Quercus with a primary focus on Quercus ellipsoidalis (northern pin oak) and Quercus rubra (northern red oak). Within this dissertation are chapters related to the setup of experimental common gardens within the Ford and Kellogg experimental forest, a literature review describing drought adaptations of Quercus sect. Lobatae (red oak group), identification of transcription factors within the Q. robur (English oak) and Q. rubra genomes, a study comparing leaf trait phenotypic plasticity of Q. ellipsoidalis and Q. rubra, and an RNA-seq experiment studying ecological speciation between Q. ellipsoidalis and Q. …
Application Of Short Tandem Target Mimic (Sttm) Technique For Functional Analysis Of Micro-Rna396 In Transgenic Poplar Trees, Surattana Boonsai
Application Of Short Tandem Target Mimic (Sttm) Technique For Functional Analysis Of Micro-Rna396 In Transgenic Poplar Trees, Surattana Boonsai
Dissertations, Master's Theses and Master's Reports
Short Tandem Target Mimic (STTM) is a commonly technique used for functional studies of a number of genes in several plant model systems. However, very little is known about application of STTM technique in tree species. In this study, STTM was applied to knock down microRNA396 (miR396) in transgenic poplar trees for the first time. STTM396 expression resulted in dramatic decrease in miR396 expression levels leading to taller plants with larger leaves and larger leaf cell size. Additionally, an expression analysis of growth regulating factor genes (GRFs) that are members of miR396 target gene family showed up-regulation of GRF07 gene …
Neutral And Adaptive Genetic Variation In North American Hardwood Tree Species, Sudhir Khodwekar
Neutral And Adaptive Genetic Variation In North American Hardwood Tree Species, Sudhir Khodwekar
Dissertations, Master's Theses and Master's Reports
'Northern Hardwoods,’ are a characteristic composition of multiple tree species and a part of the rich and diverse northeastern forests. Hardwoods e.g. oaks (Quercus: Fagaceae and Sugar maple), serve as foundation species and offer ecological and economical gains to wildlife and humans. Most of the forest trees go through many biotic and abiotic stresses, for example climate change in their long life span. To overcome these threats and to adapt to changing conditions, tree species need to maintain variation especially in adaptive genes. Therefore, it is necessary to analyze genetic diversity within forest tree populations and take appropriate …
