Habitat
And
Conservation Part #1 Pyrenean Desman

Galemys Pyrenaicus Also Threatened lives up to 3.5 years live in pairs Lives in/near mountain streams Shrew-Mole

Neurotrichus Gibbsii not a threatend species often found above ground has thirty-six teeth Part #2 Habitat Russia Ukraine Kazakhstan Ular River Volga River Don River Recently disapeared from Belarus Periodically disappears from its habitat Part #3 Why its Endangered Fixed fishing nets electric landing nets electric rods kill fish remove the desmans food pollution habitat loss Part #4 What would happen if othe species in the habitat went extinct loss of food for the desman faster extinction Natural unbalance Part #5 Possible Zoo Habitat Medium sized stream/river Some shore or land fish in the stream small lake water/marsh plants 1-2 meter depth Project #3

Natural
and
Artificial Selection The Russian Desmans Long and sensitive snout Avoid radiation high reproduction rate Avoiding predators Lives in groups Noctornal lives in a narrow niche http://www.iucnredlist.org/apps/redlist/details/6506/0 References http://en.wikipedia.org/wiki/Russian_desman reproduce with same species Part 1 use to find food often I have chosen this trait because I belive that the Russian Desmans long snout is a usefull part of its anatomy because... -it helps find food -it makes the Desman more aware of predators Part 2 -helps find a mate hunting poaching Part 3 It will take approximately 200 years for 100 generations to be completed the Desman reaches sexual maturity after two years of life usually has 3-5 offspring Part 4
