Tectonic changes that produced a deep Tasmanian Gateway between Australia and Antarctica are widely invoked as the major mechanism for Antarctic cryosphere growth and Antarctic Circumpolar Current (ACC) development during the Eocene/Oligocene (E/O) transition (∼34–33 Ma). Ocean Drilling Program (ODP) Leg 189 recovered near-continuous marine sedimentary records across the E/O transition interval at four sites around Tasmania. These records are largely barren of calcareous microfossils but contain a rich record of siliceous- and organic-walled marine microfossils. In this study we integrate micropaleontological, sedimentological, geochemical, and paleomagnetic data from Site 1172 (East Tasman Plateau) to identify four distinct phases (A–D) in …


Eocene Circulation Of The Southern Ocean: Was Antarctica Kept Warm By Subtropical Waters?, Matthew Huber, Henk Brinkhuis, Catherine E. Stickley, Kristofer Döös, Appy Sluijs Dec 2004

Eocene Circulation Of The Southern Ocean: Was Antarctica Kept Warm By Subtropical Waters?, Matthew Huber, Henk Brinkhuis, Catherine E. Stickley, Kristofer Döös, Appy Sluijs

Department of Earth, Atmospheric, and Planetary Sciences Faculty Publications

Near the Eocene's close (∼34 million years ago), the climate system underwent one of the largest shifts in Earth's history: Antarctic terrestrial ice sheets suddenly grew and ocean productivity patterns changed. Previous studies conjectured that poleward penetration of warm, subtropical currents, the East Australian Current (EAC) in particular, caused Eocene Antarctic warmth. Late Eocene opening of an ocean gateway between Australia and Antarctica was conjectured to have disrupted the EAC, cooled Antarctica, and allowed ice sheets to develop. Here we reconstruct Eocene paleoceanographic circulation in the Tasmanian region, using (1) biogeographical distributions of phytoplankton, including data from recently drilled Ocean …

Bicistronic And Fused Monocistronic Transcripts Are Derived From Adjacent Loci In The Arabidopsis Genome, Jyothi Thimmapuram, Hui Duan, Lei Liu, Mary A. Schuler Nov 2004

Bicistronic And Fused Monocistronic Transcripts Are Derived From Adjacent Loci In The Arabidopsis Genome, Jyothi Thimmapuram, Hui Duan, Lei Liu, Mary A. Schuler

Cyber Center Publications

Comparisons of full-length cDNAs and genomic DNAs available for Arabidopsis thaliana described here indicate that some adjacent loci are transcribed into extremely long RNAs spanning two annotated genes. Once expressed, some of these transcripts are post-transcriptionally spliced within their coding and intergenic sequences to generate bicistronic transcripts containing two complete open reading frames. Others are spliced to generate monocistronic transcripts coding for fusion proteins with sequences derived from both loci. RT-PCR of several P450 transcripts in this collection indicates that these extended transcripts exist side by side with shorter monocistronic transcripts derived from the individual loci in each pair. The …
