First Molecular Evidence for Underestimated Biodiversity of Rhachotropis (Crustacea, Amphipoda), with Description of a New Species

first_imgThe crustacean genus Rhachotropis has a worldwide distribution and amongst the largest bathymetric range known from any amphipod genus. DNA barcoding of new material from around New Zealand and the Ross Sea indicated depth-related biogeographic patterns. New Zealand Rhachotropis do not form a monophyletic clade. Species from bathyal depths on the Chatham Rise, east of New Zealand, show lower sequence divergence to bathyal species from California and the Arctic than to abyssal New Zealand species. Species sampled in the Kermadec Trench, north of New Zealand below 5000 m, seem to be more closely related to Ross Sea abyssal species than to the New Zealand shelf species. The worldwide geographic and bathymetric distribution for all Rhachotropis species is presented here. Depth may have a greater influence on phylogeny than geographic distance. Molecular and morphological investigations of Rhachotropis specimens from the Chatham Rise, New Zealand revealed a species new to science which is described in detail, including scanning electron microscopy. This increases the number of described species of Rhachotropis to 60 worldwide.last_img read more

Dolly Parton: Singer, Songwriter, Pandemic Savior?

first_imgShe wrote “I Will Always Love You” and “Jolene” on the same day and built a theme park around herself. She has given memorable onscreen performances as a wisecracking hairstylist and harassed secretary. She even helped bring about the creation of “Buffy the Vampire Slayer.”Now, Dolly Parton’s fans are crediting her with saving the world from the coronavirus. It’s an exaggerated, tongue-in-cheek claim, to be sure. But for legions of admirers, Ms. Parton’s donation this spring to Vanderbilt University Medical Center, which worked with the drugmaker Moderna to develop a coronavirus vaccine, was another example of how the singer’s generosity and philanthropy have made her one of the world’s most beloved artists.- Advertisement – “Shakespeare may have written King Lear during the plague, but Dolly Parton funded a Covid vaccine, dropped a Christmas album and a Christmas special,” the author Lyz Lenz said on Twitter.In April, Ms. Parton announced that she had donated $1 million to Vanderbilt after her friend Dr. Naji Abumrad, a professor of surgery at the university, in Nashville, told her about the work researchers were doing to come up with a vaccine. Dr. Abumrad’s son, Jad Abumrad, is the creator of “Radiolab” and host of the podcast “Dolly Parton’s America.”last_img read more
