Biology Faculty Publications and Presentations

Dryland ecosystems have complex vegetation communities, including subtle transitions between communities and heterogeneous coverage of key functional groups. This complexity challenges the capacity of remote sensing to represent land cover in a meaningful way. Many remote sensing methods to map vegetation in drylands simplify fractional cover into a small number of functional groups that may overlook key ecological communities. Here, we investigate a remote sensing process that further advances our understanding of the link between remote sensing and ecologic community types in drylands. We propose a method using k-means clustering to establish soft classes of vegetation cover communities from detailed …

Pi3k Signaling And Its Role In Cardiac Morphogenesis, Rabina Shrestha Jan 2024

Pi3k Signaling And Its Role In Cardiac Morphogenesis, Rabina Shrestha

Electronic Theses and Dissertations

The formation of the heart tube in vertebrates involves the coordinated movement of bilateral myocardial precursors to the midline, where they merge in a process known as cardiac fusion to form the primitive heart tube. While external influences from the anterior endoderm and the endocardium are known to be essential for cardiac fusion, intrinsic myocardial mechanisms are less understood. Here, we identify an intrinsic PI3K-dependent mechanism directing myocardial cells toward the midline during cardiac fusion. We found that inhibiting the PI3K pathway throughout the embryo using chemical inhibitors and injection of dnPI3K mRNA results in cardiac fusion defects. PI3K-inhibited embryos …
