Plant survivors of Permian-Triassic mass extinction

Originally posted on Dear Kitty. Some blog: This 26 February 2018 video from the USA says about itself: The Permian-Triassic Boundary – The Rocks of Utah The Great Dying! In this episode we head out to the Permian-Triassic boundary and try to discover what caused Earth’s Largest mass extinction event, 252 million years ago. After 4-months of research, I’m excited to finally release this exciting video! A pre-print of the scientific paper is available here. I’ve submitted this research to the journal “Global and Planetary Change” for peer review. By Laurel Hamers, 2:12pm, December 20, 2018: More plants survived the world’s greatest mass extinction than thought Fossils in a Jordanian desert reveal plant lineages that didn’t perish in the Great Dying Some ancient plants were survivors. A collection of roughly 255-million-year-old fossils suggests that three major plant groups existed earlier than previously thought, and made it through a mass extinction that wiped out more than 90 percent of Earth’s marine species and roughly 70 percent of land vertebrates. The fossils, described in the Dec. 21 Science, push back the earliest records of these plant groups by about 5 million years. “But it’s not just any 5 million years — it’s those 5 million years that span the Permian-Triassic boundary”, says study coauthor Benjamin Bomfleur, a paleobotanist at the University of Münster in Germany. The find adds to the growing list of land plants that survived the catastrophe known as…

Male Borneo frogs take care of tadpoles

Originally posted on Dear Kitty. Some blog: This 16 October 2018 video from the USA says about itself: Johana Goyes-Vallejos (UConn and KU): Do Female Frogs Call? Dr. Johana Goyes-Vallejos discovers that in the smooth guardian frog of Borneo, female frogs call. In frog species, typically male frogs call, while females stay silent. Dr. Johana Goyes-Vallejos shows that in the smooth guardian frog of Borneo (Limnonectes palavanensis) this is not the case and that female frogs call, too, producing spontaneous vocalizations to attract males. Dr. Goyes-Vallejos’ discovery that female frogs call suggests that L. palavanensis exhibits a reversal in calling behavior and possibly a sex-role-reversed mating system, which would be the first ever observed in a frog species. Speaker Biography: Johana Goyes Vallejos received her bachelor’s degree in Biology from Universidad del Valle, in Cali, Colombia. For her Ph.D., she joined the lab of Dr. Kentwood Wells in the Ecology and Evolutionary Biology Department at the University of Connecticut. Johana’s research interests include sexual selection and amphibian mating systems (frogs and toads), with a particular interest in species that exhibit parental care behavior. For her dissertation work, she focused on elucidating the mating system of the smooth guardian frog of Borneo (Limnonectes palavanensis), an unusual species about which very little was known when she began her work. Using a combination of extensive fieldwork, bioacoustics, and methods in behavioral ecology and animal communication, Johana described behaviors of this species that…
