Cascade speciation and reinforcement can evolve rapidly when traits are pleiotropic and act as both signal/cue in non-random mating. Reproductive isolation due to these traits can be rapid, facilitating cascade speciation ...
Many tree species have seedling recruitment patterns suggesting that they are affected by non-competitive distance-dependent sources of mortality. We conducted an experiment, with landscape-level replication, to identify ...
We analyzed the usage and consequences of alternative cleavage and polyadenylation (APA) in $\textit{Drosophila melanogaster}$ by using >1 billion reads of stranded mRNA-seq across a variety of dissected tissues. Beyond ...
In humans, chronic inflammation, severe injury, infection and disease can result in changes in steroid hormone titers and delayed onset of puberty; however the pathway by which this occurs remains largely unknown. Similarly, ...
The ecdysone receptor is a heterodimer of two nuclear receptors, the Ecdysone receptor (EcR) and Ultraspiracle (USP). In $\textit{Drosophila melanogaster}$, three EcR isoforms share common DNA and ligand-binding domains, ...

Epigenetic regulation exerts a major influence on origins of DNA replication during development. The mechanisms for this regulation, however, are poorly defined. We showed previously that acetylation of nucleosomes regulates ...
Transcription activator-like (TAL) effectors are repeat-containing proteins used by plant pathogenic bacteria to manipulate host gene expression. Repeats are polymorphic and individually specify single nucleotides in the ...
Standage, D.S.; Brendel, V.P.(BioMed Central Ltd., 2012)
Background: Accurate gene structure annotation is a fundamental but somewhat elusive goal of genome projects, as witnessed by the fact that (model) genomes typically undergo several cycles of re-annotation. In many cases, ...
In plants, RNA silencing-based antiviral defense is mediated by Dicer-like (DCL) proteins producing short interfering (si)RNAs. In $\textit{Arabidopsis}$ infected with the bipartite circular DNA geminivirus $\textit{Cabbage ...
Multisubunit RNA polymerases IV and V (Pol IV and Pol V) evolved as specialized forms of Pol II that mediate RNA-directed DNA methylation (RdDM) and transcriptional silencing of transposons, viruses, and endogenous repeats ...
Therese, M.O.; Bashey, F.(American Society of Parasitologists, 2012)
Trans-host effects can alter the ecological and evolutionary dynamics of parasite and host populations. Here, we examine whether resource limitation within a parasite's natal host affects propagule size and influences ...

We approach conceptual issues in evolutionary biology from an endocrinological perspective, noting that single hormones typically act on several target tissues and thereby mediate suites of correlated phenotypic traits. ...
Ketterson, Ellen D.; Nolan, Val Jr; Wolf, Licia; Ziegenfus, Charles(American Society of Naturalists, 1992-12)
Hormones influence many aspects of organismal behavior, physiology, and morphol- ogy, and thus hormones may lie at the root of many life-history trade-offs. By manipulating hormones we can create novel phenotypes (i.e., ...
Ketterson, Ellen D.; Nolan, Val Jr(American Society of Naturalists, 1992-11)
Because of their role in mediating life‐history trade‐offs, hormones are expected to be strongly associated with components of fitness; however, few studies have examined how natural selection acts on hormonal variation ...

The Ordinary Extraordinary Junco is a documentary film project designed to engage, entertain, and inspire student and adult audiences of all backgrounds. The feature-length film (88 min.) is comprised of eight shorter video ...
