© 2016 the American Physiological Society. Life cycle delays are beneficial for opportunistic species encountering suboptimal environments. Many animals display a programmed arrest of development (diapause) at some stage(s) of their development, and the diapause state may or may not be associated with some degree of metabolic depression. In this review, we will evaluate current advancements in our understanding of the mechanisms responsible for the remarkable phenotype, as well as environmental cues that signal entry and termination of the state. The developmental stage at which diapause occurs dictates and constrains the mechanisms governing diapause. Considerable progress has been made in …

© The Author 2016. Published by Oxford University Press on behalf of the Annals of Botany Company. Background and Aims Many gymnosperms produce an ovular secretion, the pollination drop, during reproduction. The drops serve as a landing site for pollen, but also contain a suite of ions and organic compounds, including proteins, that suggests diverse roles for the drop during pollination. Proteins in the drops of species of Chamaecyparis, Juniperus, Taxus, Pseudotsuga, Ephedra and Welwitschia are thought to function in the conversion of sugars, defence against pathogens, and pollen growth and development. To better understand gymnosperm pollination biology, the pollination …
Effects Of Premature Birth And/Or Low Birthweight On Developmental Outcomes, Rachel L. Goldin
Effects Of Premature Birth And/Or Low Birthweight On Developmental Outcomes, Rachel L. Goldin
LSU Doctoral Dissertations
Advances in neonatal technology have improved survival rates of children born at lower and lower birthweight and after fewer and fewer weeks of gestation. However, these children are at increased risk of experiencing developmental delays. As weeks of gestation and birthweight decrease, the risk of developmental impairment and severity increases. Yet to be determined is whether premature birth and low birthweight (LBW) effect development differentially, and if the combined, have an additive effect on developmental outcomes. The first part of this study aimed to examine the independent effects of preterm birth and LBW in children at risk for developmental delays. …

Developing Mediators: An Analysis Of The Changing Associations Of Ghanaian Internet Cafe Users Between 2003 And 2014, Matthew Gregory Leblanc
LSU Doctoral Dissertations
This study examines interview data gathered a decade apart, in 2003 and in 2014.The analysis answers the questions: "How were café patrons using the Internet in 2003 and how do the 2003 findings of this study compare to the findings of other studies conducted around the same time?" "How has Internet usage changed between 2003 and 2014?" "How has the Internet café business changed over the last decade?" This study starts by reviewing the theory and literature which informs studies of the Internet and Internet cafés in developing countries. Two years were spent discovering the fate of the 2003 locations. …
