Insect Developmental Plasticity: The Role In A Changing Environment, Lindsey A. Barnes
Insect Developmental Plasticity: The Role In A Changing Environment, Lindsey A. Barnes
The Cardinal Edge
Climate change has been recognized as a severe threat to biodiversity. In the rapidly growing collection of literature on the consequences of global change, researchers have recently noticed a dramatic decrease in insect populations in a wide range of habitats. Insects are extremely susceptible to climatic change, especially with regard to fluctuations in moisture and temperature. However, insects often exhibit phenotypic plasticity, where organisms will express different phenotypes when presented with a specific environmental stimulus. In developmental plasticity, environmental stimuli at the larval stage can determine adult phenotypes. This review focuses on case studies of developmental plasticity in insects, with …
The Effects Of Alcohol On The Developing Drosophila Nervous System, Erica E. Hassoun
The Effects Of Alcohol On The Developing Drosophila Nervous System, Erica E. Hassoun
The Cardinal Edge
Ethanol is the most common human teratogen, contributing to fetal alcohol syndrome (FAS) when effects are the most severe. Key effects of fetal alcohol syndrome are observed in the nervous system. The high prevalence of prenatal alcohol exposure necessitates novel treatment and prevention methods. However, ethical issues prevent researching humans in utero. For this reason, the fruit fly Drosophila melanogaster has emerged as a model organism for studying FAS. Because Drosophila is a small and non-placental organism, its environment can be easily controlled, allowing for specific doses and time periods of ethanol exposure to be studied. This review discusses findings …
Regulation Of Genome Architecture By Chromatin Remodeling In The Brain, Jared Vega Goodman
Regulation Of Genome Architecture By Chromatin Remodeling In The Brain, Jared Vega Goodman
Arts & Sciences Electronic Theses and Dissertations
Brain development requires exquisite control of gene expression to establish and refine the proper circuitry of the nervous system. Gene expression control is under the purview of several cellular processes, including chromatin regulation in the form of DNA modification, histone modification, and nucleosome remodeling. Chromatin remodeling enzymes are the major effectors of nucleosome remodeling. These enzymes are clearly involved in brain development – mutations in chromatin remodeling enzymes are likely causative for neurodevelopmental disorders of cognition. Chromatin remodeling enzymes have discrete molecular functions and binding profiles and similarly control distinct phases of nervous system maturation. Chd4 is a Chd family …
The Phoenix, Fernanda Perez-Alvarez
The Phoenix, Fernanda Perez-Alvarez
Montserrat Annual Writing Prize
This article uses a mythical creature, the phoenix, to examine and illustrate the biological principles for generation of an adult body plan from a single cell. Using the study of developmental biology, it explores the cellular and molecular biology that underpins the massive complexity of creating an adult body plan. It also explores the similarities and differences between different embryos, and how nature and evolution have shaped the biology of those embryos to create different body plans.
