Email: Wolverines are rare even in the places they're known to live but in Calgary city limits, they're unheard-of. A place that seems like its locally extinct can be repopulated very quickly, because if the babies are coming from somewhere else, not locally, then repopulation can occur really quickly, Raimondi said.

The Canada Revenue Agency says grocery rebate scams are circulating by text and email, urging recipients to claim payments or fill out forms. We analyzed sea star counts, biomass, size distributions, and recruitment from long-term intertidal monitoring sites from San Diego to Alaska to assess regional trends in sea star recovery following the outbreak. In this era of rapidly changing ocean conditions, we need to develop better, more nimble strategies to respond to future sudden marine die-off events and ecosystem declines.. Mobile Terms & Conditions In general, sea star wasting appears to be stubbornly persisting at a low level in most areas. These animals can be important predators of sea urchins and the loss of sunflower sea stars along with other predators has been associated with explosions of purple urchin populations in some parts of the West Coast.
