Owner behavior affects effort and accuracy in dogs’ communications

Researchers have found that dogs adapt their communicative strategies to their environment and that owner behavior influences communicative effort and success. Experimental results found no evidence that dogs rely on communication history or follow the principle of least effort and suggest that owner behavior has a bigger impact on canine communication than previously thought.

Global e-waste surging: Up 21% in 5 years

(Terry Collins Assoc) The UN’s 3rd Global eWaste Monitor reports 53.6 million metric tonnes (Mt) of e-waste was produced last year — substantially more than the weight of all adults in Europe. Global e-waste has risen 21% by weight in just five years, fueled by higher consumption rates of electric and electronic equipment, short life cycles, and few repair options. In 2030 the world is projected to produce about 50% more e-waste per capita compared with 2014.

Social information encoded in their echolocation calls may facilitate this foraging strategy that allows them to find food faster.
