Coypu rats (Nutria)
Native to South America, it has been introduced to North America, Europe, Asia, and Africa, primarily by fur harvesters. However, populations have exploded and the species's feeding habits damage river plant biodiversity which harms native species which rely on the river plants for food
The largest true bird of prey, the Cinereous Vulture, has a specialized blood chemical that allows for it to take in sufficient oxygen at extreme heights. This allows it to see prey from a great distance over the relatively flat biome.
This species possesses many adaptations. Variations in coloration camouflages the Siberian Ibex in its environment. Its hooves are also specialized for climbing rocky surfaces and remaining balanced. The horns are used to attract mates.
The Saiga Antelope's large nasal cavity allows for frigid air to be warmed as it is inhaled. This is useful in winter when it must eat sparse vegetation that is covered in snow.
Russian Thistle (Tumbleweed)
When the plant is mature enough to reproduce, rather than relying on wind, animals, etc to scatter seeds, it breaks off at the base and as the wind causes it to tumble, the seeds fall off the plant.
This plant has a very long root system that allows it to draw water from depths most plants cannot reach. Milk Vetch is also a perennial plant. This means the portion above the ground dies off during winter so that it requires fewer nutrients. In the spring the root system gives way to a new flowering plant.
This plant has a highly adaptable root system. If the water level is low, it will grow deep taproots and if the level is high, it grows lots of surface roots. This allows for the plant to survive droughts that commonly occur in the Steppe.
