dog : a highly variable domestic mammal (Canis familiaris) closely related to the gray wolf — Webster
Domestic dog (Canis lupus familiaris when considered a subspecies of the wolf or Canis familiaris when considered a distinct species) is a member of the genus Canis (canines), which forms part of the wolf-like canids, and is the most widely abundant terrestrial carnivore. The dog and the extant gray wolf are sister taxa as modern wolves are not closely related to the wolves that were first domesticated, which implies that the direct ancestor of the dog is extinct. The dog was the first species to be domesticated and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes. — Wikipedia

- Using snakes to monitor Fukushima radiationon July 20, 2021 at 7:52 pm
Ten years after one of the largest nuclear accidents in history spewed radioactive contamination over the landscape in Fukushima, Japan, a University of Georgia study has shown that radioactive contamination in the Fukushima Exclusion Zone can be measured through its resident snakes.
- DNA assay aids in identifying and protecting...on July 20, 2021 at 6:06 pm
Forensics specialists can use a commercial assay targeting mitochondrial DNA to accurately discriminate between wolf, coyote and dog species, according to a new study from North Carolina State University. The genetic information can be obtained from smaller or more degraded samples, and could aid authorities in prosecuting hunting jurisdiction violations and preserving protected species.
- New method allows unambiguous identification of...on July 19, 2021 at 12:55 pm
Together with a European team, Senckenberg scientists have presented a new method in the scientific journal BMC Genomics that allows the reliable identification of wolf-dog hybrids on the basis of environmental samples such as feces, hair, or saliva residue. The method has a much higher resolution than conventional methods and is expected to serve as a standard procedure in the future, allowing for comparable detection of hybridization rates across Europe.
