Aspergillus is a member of the Deuteromycetes fungi, which is a group with no known sexual state. With DNA evidence forthcoming, all members of the genus Aspergillus likely are closely related and should be considered members of the Ascomycota.Members of the genus possess the ability to grow where a high osmotic concentration (high sugar, salt, etc.) exists.spergillosis is the group of diseases caused by Aspergillus. The most common subtype among paranasal sinus infections associated with aspergillosis is A. fumigatus. The symptoms include fever, cough, chest pain, or breathlessness, which also occur in many other illnesses, so diagnosis can be difficult.
Polar Bear. Common Names: Sea Bear. Genus: Ursus. Species: maritimus. Polar bears can be found all through the polar regions of the Northern hemisphere. They are the largest carnivore on land. They have a black nose and eyes. They have two layers of fur which is so warm that adult bears can easily overheat when they run.
Although most polar bears are born on land, they spend most of their time at sea. Their scientific name means  maritime bear, and derives from this fact. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present.The polar bear is classified as a vulnerable species, with eight of the nineteen polar bear subpopulations in decline.For decades, large scale hunting raised international concern for the future of the species but populations rebounded after controls and quotas began to take effect.t is a large bear, approximately the same size as the omnivorous Kodiak bear (Ursus arctos middendorffi). A boar (adult male) weighs around 350â700 kg (772â1,543 lb), while a sow (adult female) is about half that size.
