Polar bear

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.

Xanthomonas melonis is a gram-negative plant-pathogenic bacterium in the family Xanthomonadaceae, causing bacterial spot disease on melon (Cucumis melo) and related cucurbit crops. It produces characteristic yellow-pigmented colonies and spreads via contaminated seed and water. Its conservation status is not evaluated.
