Polar ecosystems are sensitive to climate forcing, and we often lack baselines to evaluate changes. Here we report a nearly 50-year study in which a sudden shift in the population dynamics of an ecologically important, structure-forming hexactinellid sponge, Anoxycalyx joubini was observed. This is the largest Antarctic sponge, with individuals...
Despite knowledge that concerted evolution of high-copy loci is often imperfect,
studies that investigate the extent of intragenomic polymorphisms and comparisons
across a large number of species are rarely made. We present a bioinformatic pipeline
for characterizing polymorphisms within an individual among copies of a high-copy
locus. Results are presented...

Horizontal gene transfer (HGT) of DNA from the plastid to the nuclear and mitochondrial genomes of higher plants is a common
phenomenon; however, plastid genomes (plastomes) are highly conserved and have generally been regarded as impervious to HGT.
We sequenced the 158 kb plastome and the 690 kb mitochondrial genome...

The current study examines the effects of prekindergarten quality and quantity on externalizing
behavior problems for children living in non-parental care, compared to other children from
socioeconomically at-risk backgrounds. Data were obtained from the Head Start Impact Study.
Non-parental care was defined as a primary caregiver other than a biological,...

The current study examines the effects of Head Start on the development of school readiness outcomes for children living in non-parental care. Data were obtained from the Head Start Impact Study, a randomized controlled trial of Head Start conducted with a nationally representative sample of Head Start programs and families....
