Hace 5 días · A new study explores DNA samples from nearly 1,000 Daphnia, revealing new subtleties in the evolutionary processes of natural selection. Graphic by Jason Drees. In new research, Arizona State University scientists and their colleagues investigated genetic changes occurring in a naturally isolated population of the water flea, Daphnia pulex.

Unit 731 ( Japanese: 731部隊, Hepburn: Nana-san-ichi Butai), [note 1] short for Manchu Detachment 731 and also known as the Kamo Detachment [3] : 198 and the Ishii Unit, [5] was a covert biological and chemical warfare research and development unit of the Imperial Japanese Army that ...
Hace 1 día · Amphipods range in size from a millimetre in length to the supergiant amphipod Alicella gigantea at 340 mm. Amphipods can be found in all marine habitats (even the deepest ocean trenches e.g. Hirondellea dubia ), and have also colonised freshwaters and terrestrial habitats; even ectoparasitic groups are also known among them.
Hace 2 días · In new research, Arizona State University scientists and their colleagues investigated genetic changes occurring in a naturally isolated population of the water flea, Daphnia pulex. This tiny crustacean, barely visible to the naked eye, plays a crucial role in freshwater ecosystems and offers a unique window into natural selection and evolution.
