• Borealodon osedax, a new stem mysticete (Mammalia, Cetacea) from the Oligocene of Washington State and its implications for fossil whale-fall communities 

  Shipps, B. K.; Peredo, Carlos Mauricio; Pyenson, Nicholas D. (2019)

  Baleen whales (mysticetes) lack teeth as adults and instead filter feed using keratinous baleen plates. They do not echolocate with ultrasonic frequencies like toothed whales but are instead known for infrasonic acoustics. ...

  It has long been appreciated that analyses of genomic data (e.g., whole genome sequencing or sequence capture) have the potential to reveal the tree of life, but it remains challenging to move from sequence data to a clear ...
• A key to the North American genera of Stipeae (Poaceae, Pooideae) with descriptions and taxonomic names for species of <I>Eriocoma</I>, <I>Neotrinia</I>, <I>Oloptum</I>, and five new genera: <I>Barkworthia</I>, ×<I>Eriosella</I>, <I>Pseudoeriocoma</I>, <I>Ptilagrostiella</I>, and <I>Thorneochloa</I> 

  Peterson, Paul M.; Romaschenko, Konstantin; Soreng, Robert J.; Valdés Reyna, Jesus (2019)

  Based on earlier molecular DNA studies we recognize 14 native Stipeae genera and one intergeneric hybrid in North America. We provide descriptions, new combinations, and 10 illustrations for species of Barkworthia gen. ...
