Status and trends of circumpolar peregrine falcon and gyrfalcon populations.

The peregrine falcon (Falco peregrinus) and the gyrfalcon (Falco rusticolus) are top avian predators of Arctic ecosystems. Although existing monitoring efforts are well established for both species, collaboration of activities among Arctic scientists actively involved in research of large falcons in the Nearctic and Palearctic has been poorly coordinated. Here we provide the first overview of Arctic falcon monitoring sites, present trends for long-term occupancy and productivity, and summarize information describing abundance, distribution, phenology, and health of the two species.

RNA-Seq Analysis of Differential Splice Junction Usage and Intron Retentions by DEXSeq.

Alternative splicing is an important biological process in the generation of multiple functional transcripts from the same genomic sequences. Differential analysis of splice junctions (SJs) and intron retentions (IRs) is helpful in the detection of alternative splicing events. In this study, we conducted differential analysis of SJs and IRs by use of DEXSeq, a Bioconductor package originally designed for differential exon usage analysis in RNA-seq data analysis.

Half pint/Puf68 is required for negative regulation of splicing by the SR splicing factor Transformer2.

The SR family of proteins plays important regulatory roles in the control of alternative splicing in a wide range of organisms. These factors affect splicing through both positive and negative controls of splice site recognition by pre-spliceosomal factors. Recent studies indicate that the Drosophila SR factor Transformer 2 (Tra2) activates and represses splicing through distinct and separable effector regions of the protein.
