Using state-of-the-art robotics, a research team from the University of Konstanz, Science of Intelligence, and the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) shows that animals’ speed is fundamental for collective behavioral patterns, and that ultimately it is the faster individuals that have the strongest influence on group-level […]

ANIMATION Sharks’ non-bony skeletons were thought to be the template before bony internal skeletons evolved, but a new fossil discovery suggests otherwise. The discovery of a 410-million-year-old fish fossil with a bony skull suggests the lighter skeletons of sharks may have evolved from bony ancestors, rather than the other way […]

Researchers “counted” Japanese jack mackerel (Trachurus japonicus) in Maizuru Bay, Japan, through quantitative measurements of environmental DNA concentration. Credit: Reiji Masuda, Kyoto University River water, lake water, and seawater contain DNA belonging to organisms such as animals and plants. Ecologists have begun to actively analyze such DNA molecules, called environmental DNA, to […]

The 75-station pattern is typical for summer and fall cruises by CalCOFI, which has collected data on marine life and ocean conditions off the California coast. The original 1950s sampling plan was similar but covered a larger area, from the northern tip of California to the southern tip of the […]
