The Taiga Ecosystem Mr. Calderon Biology What is the Taiga ecosystem? • Taiga is Russian for forest…specifically for evergreen forests (e.g., Pine trees, Spruce, etc.) • Also called the Coniferous, or Boreal Forests. • “Boreal” was the Greek goddess of the North Wind! • Taiga is located in the high northern latitudes. • Winters are harsh (-65 to 30° F) and food is limited. • Many animals deal with these winters by either migrating south, hibernating, or having certain traits that help them survive the winter. • Summers are warm (70°F), rainy, and humid in the Taiga. • Spring and Fall seasons are so short, you hardly know they exist. • It is either hot and humid or very cold in the taiga. Example Trophic Pyramid of Taiga Siberian Tiger (Panthera tigris altaica) Eurasian Lynx (Lynx lynx) Snowshoe Hare (Lepus americanus) Douglas Fir (Pseudotsuga menziesii) Wolverine (Gulo gulo) Eurasian Red Squirrel (Sciurus vulgaris) Caribou moss (Cladonia rangifernia) Primary Energy Source Decomposers • Soil Bacteria • The Sun! • Roundworms (Nematodes) • Sow Bug (Armidillidium vulgare) • Honey Fungus (Armillariella mellea) A closer look at two Taiga species! • • • • • • • • • Siberian Tiger Domain: Eukarya Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Carnivora Family: Felidae Genus: Panthera Species: P. tigris Subspecies: P. tigris altaica Wolverine • Domain: Eukarya • Kingdom: Animalia • Phylum: Chordata • Class: Mammalia • Order: Carnivora • Family: Mustelidae • Genus: Gulo • Species: G. gulo Advantageous traits: Siberian Tiger • Wide paws for running through snow* Wolverine • Dense fur for cold temperatures* • Striped for blending in vegetation when sneaking up on prey during summer • Keen sense of smell for finding carrion (decaying flesh)* • Solitary lifestyle in food limited environment means less food to find.* • Cache/store extra food in snow for when food may not be available later. * Applies to both species Interesting Facts: Siberian Tiger • Considered to have a top 15 strongest bite in animal kingdom. • Adult male Siberian tigers can weigh up to 700 lb. while females weigh up to 400 lb. • Siberian tigers are considered endangered by IUCN’s Red List. • Causes of their dwindling population is loss of habitat due to deforestation, and poaching for their fur and for body parts that are used for traditional Chinese medicines. Wolverine • Their territories can range from 40 miles (65 km) to more than 372 miles (600 km). • The wolverine's scientific name comes from the Latin word gulo, which means "glutton." • M56 is a wolverine that was fitted with a tracking device near Grand Teton National Park in Wyoming. During just two months, the wolverine walked more than 500 miles.
