Sauropod Vegetation

Dinosaur Food Experiment

Dinosaur food experiment described in ScienceDaily and Palaeontology, doi: 10.1111/pala.12385. Dinosaur experts have long been intrigued by how giant sauropods were able to get enough food to provide energy and maintain their large bodies. One theory is that the levels of carbon dioxide (CO2) in the air were higher in Mesozoic eras and plants therefore […]

Clams Recycle Urea for Algae

Clams recycle urea for algae, according to reports in Inside JEB 19 April 2018, and Journal of Experimental Biology 14 March 2018, doi: 10.1242/jeb.176313. Giant clams live in close symbiotic relationship with marine algae known as zooxanthellae, which produce nutrients for the clam by photosynthesis.  The algae can make sugars from carbon dioxide and water, […]

Rain Spreads Crop Diseases

Rain spreads crop diseases, according to an article in ScienceDaily 20 November 2017. Previous research has shown that raindrops can spread microscopic pathogens, i.e. disease causing bacteria, viruses and fungi. A team of researchers at the Department of Biomedical Engineering and Mechanics at Virginia Tech have now studied how the spread actually happens, using laser […]
