‘The Science Of Cats’ course finds popularity among college students (Links to an external site)

Jonathan Losos, a distinguished Professor of Biology at Washington University in St. Louis and the Director of the Living Earth Collaborative, teaches a unique course titled “The Science of Cats” at Washington University. The course has captured the interest of students and cat enthusiasts alike. Listen in as Jonathan discusses this course on Wake Up Call, a program on KFI AM 640.

Missouri native is flowering earlier due to climate change (Links to an external site)

Matthew Austin, an ecologist and biodiversity postdoctoral fellow with the Living Earth Collaborative at Washington University in St. Louis, published a study in the American Journal of Botany that describes changes to the flowering time and other important life cycle events in Leavenworthia species, a group of small flowering plants found in glades in Missouri.

No, autumn leaves are not changing color later because of climate change (Links to an external site)

Many people believe that climate change is pushing back the start of fall leaf color to later in the year. The general thinking is that the warmer conditions anticipated under climate change will mean that trees can “hang on” to their green, energy-producing leaves longer. But scientists do not actually see this happening across North American forests, according to LEC Biodiversity Fellow, Susanne S. Renner, an expert at Washington University in St. Louis.

Watermelon cut into triangles

The oldest known seeds from a watermelon relative, dating back 6,000 years to the Neolithic period, were found during an archaeological dig in Libya. An investigation of these seeds led by LEC Biodiversity Fellow, biologist Susanne S. Renner at Washington University in St. Louis, reveals some surprises about how our ancestors used a predecessor of today’s watermelon.

With funding support from LEC, researchers look at whether Ozark oases at Tyson Research Center — climate change refugia — could help species persist in spite of rising temperatures.

St. Louis, MO – Sustainable Cities (Links to an external site)

Looking at the STL Arch from Illinois

Low-income communities and communities of color are disproportionately harmed by air pollution from burning fossil fuels and by the health risks of climate change. Transitioning away from fossil fuels takes economic and political support, a difficult ask for St. Louis, a city located in a state with one of the highest rates of coal consumption in the country. New technical and scientific funding support from foundations, combined with a recent push by city leaders, religious communities, and clean energy advocates, is putting in place sustainability programs and policies that are moving the Midwest city in a new direction.

Jane Melville, senior curator of terrestrial vertebrates at Museums Victoria and associate professor in the School of Biological Sciences at Monash University, led the collaborative research effort to emphasize the importance of prioritizing taxonomic research in conservation as part of a Fulbright Fellowship at Washington University in St. Louis.

A seedy slice of history: Watermelons actually came from northeast Africa (Links to an external site)

A new study published in the Proceedings of the National Academy of Sciences rewrites the origins of domesticated watermelons. The study corrects a 90-year-old mistake that lumped watermelons into the same category as the South African citron melon. Instead, researchers, including Susanne S. Renner, a first author now at Washington University in St. Louis, found that a Sudanese form with non-bitter whitish pulp, known as the Kordofan melon (C. lanatus), is the closest relative of domesticated watermelons.

Andean forests have high potential to store carbon under climate change. The study — which draws upon two decades of data from 119 forest-monitoring plots in Colombia, Ecuador, Peru, Bolivia and Argentina — was produced by an international team of scientists including researchers supported by the Living Earth Collaborative at Washington University in St. Louis. The lead author was Alvaro Duque from the Universidad Nacional de Colombia Sede Medellín.

Plant leaves showing powdery mildew

New research from an international team including Rachel Penczykowski, an assistant professor of biology at Washington University in St. Louis shows that infection actually makes a plant more susceptible to secondary infection — in experiments and in the wild. The findings are published Aug. 31 in Nature Ecology & Evolution.

A study published July 8 in the journal Nature Plants presents a novel model for how small-seeded plants came to the table — and it relies on help from large, grazing animals, including bison. The new work is a collaboration between Natalie Mueller, assistant professor of anthropology in Arts & Sciences at Washington University in St. Louis, and Robert Spengler, director of the Paleoethnobotany Laboratories at the Max Planck Institute for the Science of Human History.
