for use for several hours that day while the upgrade is in progress. Deposits to DukeSpace
will be disabled on Monday December 11, so no new items are to be added to the repository
while the upgrade is in progress. Everything should be back to normal by the end of
day, December 12.

Dynamic evolution of base composition: causes and consequences in avian phylogenomics.
(Mol Biol Evol, 2011-08)Resolving the phylogenetic relationships among birds is a classical problem in systematics, and this is particularly so when it comes to understanding the relationships among Neoaves. Previous phylogenetic inference of birds ... -
Evidence for GC-biased gene conversion as a driver of between-lineage differences in avian base composition.
(Genome Biol, 2014)BACKGROUND: While effective population size (Ne) and life history traits such as generation time are known to impact substitution rates, their potential effects on base composition evolution are less well understood. GC ... -
Genes Translocated into the Plastid Inverted Repeat Show Decelerated Substitution Rates and Elevated GC Content.
(Genome biology and evolution, 2016-08-25)Plant chloroplast genomes (plastomes) are characterized by an inverted repeat (IR) region and two larger single copy (SC) regions. Patterns of molecular evolution in the IR and SC regions differ, most notably by a reduced ... -
Retrotransposons Are the Major Contributors to the Expansion of the Drosophila ananassae Muller F Element.
(G3 (Bethesda, Md.), 2017-08-07)The discordance between genome size and the complexity of eukaryotes can partly be attributed to differences in repeat density. The Muller F element (∼5.2 Mb) is the smallest chromosome in Drosophila melanogaster, but it ... -
Unprecedented loss of ammonia assimilation capability in a urease-encoding bacterial mutualist.
(BMC Genomics, 2010-12-02)BACKGROUND: Blochmannia are obligately intracellular bacterial mutualists of ants of the tribe Camponotini. Blochmannia perform key nutritional functions for the host, including synthesis of several essential amino acids. ...
