It wasn’t long ago that bed bugs were just an uncomfortable memory from a bygone era. However, the blood-sucking critters have recently staged a remarkable comeback, and with it new industries have emerged with the aim of tracking and eradicating the irritating pests.
The dung beetle dance, performed as the beetle moves away from the dung pile with his precious dung ball, is a mechanism to maintain the desired straight-line departure from the pile, according to a study published in the Jan. 18 issue of the online journal PLoS ONE.
The Freshwater Pearl Mussel, Margaritifera margaritifera, is listed as ‘Endangered’ on the IUCN Red List of Threatened Species™. Its distribution stretches from northern Spain through France, the United Kingdom and central Europe, to Scandinavia and northern Russia. Individuals develop very slowly; in Sweden, recently discovered specimens are up to 280 years old.
