Congruent Phylogenetic Relationships Of Melaphidina Aphids (Aphididae: Eriosomatinae: Fordini) According To Nuclear And Mitochondrial Dna Data With Taxonomic Implications On Generic Limits, Zhumei Ren, Carol D. Von Dohlen, A. J. Harris, Rebecca B. Dikow, Xu Su, Jun Wen

Biology Faculty Publications

Melaphidina aphids (Rhus-gall aphids; Eriosomatinae: Fordini) comprise five genera from eastern Asia and one monotypic genus from eastern North America. Melaphidina are unique in feeding on plant species of Rhus subgenus Rhus (Anacardiaceae), on which they form galls during the summer. The phylogenetic relationships among some species of Melaphidina aphids remain controversial. In this study, we sought to resolve the backbone phylogeny of Melaphidina aphids by sampling 15 accessions representing all six genera, all species, and all subspecies except Meitanaphis microgallis using 20 gene regions: five nuclear genes as well as 13 protein-coding genes and two rRNA genes …

Peninsula Medical School

Parkinson's disease (PD) and Alzheimer's disease (AD) are the most common neurodegenerative diseases and have been suggested to share common pathological and physiological links. Understanding the cross-talk between them could reveal potentials for the development of new strategies for early diagnosis and therapeutic intervention thus improving the quality of life of those affected. Here we have conducted a novel meta-analysis to identify differentially expressed genes (DEGs) in PD microarray datasets comprising 69 PD and 57 control brain samples which is the biggest cohort for such studies to date. Using identified DEGs, we performed pathway, upstream and protein-protein interaction analysis. We …

On The Shoulders Of Giants: Continuing The Legacy Of Large-Scale Ecosystem Manipulation Experiments In Puerto Rico, Tana E. Wood, Grizelle González, Whendee L. Silver, Sasha C. Reed, Molly A. Cavaleri

College of Forest Resources and Environmental Science Publications

There is a long history of experimental research in the Luquillo Experimental Forest in Puerto Rico. These experiments have addressed questions about biotic thresholds, assessed why communities vary along natural gradients, and have explored forest responses to a range of both anthropogenic and non-anthropogenic disturbances. Combined, these studies cover many of the major disturbances that affect tropical forests around the world and span a wide range of topics, including the effects of forest thinning, ionizing radiation, hurricane disturbance, nitrogen deposition, drought, and global warming. These invaluable studies have greatly enhanced our understanding of tropical forest function under different disturbance regimes …

Online Learning, Offline Outcomes: Online Course Taking And High School Student Performance, Cassandra M.D. Hart, Dan Berger, Brian Jacob, Susanna Loeb, Michael Hill

Benerd College Faculty Articles

This article uses fixed effects models to estimate differences in contemporaneous and downstream academic outcomes for students who take courses virtually and face-to-face—both for initial attempts and for credit recovery. We find that while contemporaneous outcomes are positive for virtual students in both settings, downstream outcomes vary by attempt type. For first-time course takers, virtual course taking is associated with decreases in the likelihood of taking and passing follow-on courses and in graduation readiness (based on a proxy measure). For credit recovery students, virtual course taking is associated with an increased likelihood of taking and passing follow-on courses and being …
