Heteromorphic Ammonoids of the Matanuska Formation, Turonian, Alaska
Julia and Eugene Porotov
Element: Siberian taiga (flora and fauna)
The taiga, or boreal forest, constitutes the majority of forest mass in the planet and is formed by immense coniferous forests resistant to the cold. This type of environment is found in Russia, Europe and Siberia, the North of Europe, North of Canada and Alaska. The animals that live in these zones are able to survive in long and hard winters. the Siberian taiga cover, only, one large area of the United States. In the illustration, the author represents the plants and animals typical of this region. Between the animals we find herbivores such as elks and wild boar and carnivores such as lync, brown bears, wolves and foxes.

Especie: Lucanus cervus
The Stag beetle, Lucanus cervus, is the biggest beetle in Europe well known for the enlarged mandibles of the males (II). The species is sexually dimorphic, that is, males and female are different in morphology. The male has enlarged mandibles and is also larger than female. Females lay their eggs in a piece of decaying wood, deep in the soil. Stag beetle larvae feed on rotting wood for several years. The larvae go through several instar stages, taking 4 to 6 years to become pupae (I). Adults emerge in summer to mate and only live for a few weeks. In the Iberian Peninsula Lucanus cervus has been associated with a range of deciduous trees like Quercus and Castanea sativa (III). The loss of its natural habitat caused by human activities and bad forestry management (for example, removing decaying wood from forests) makes this species vulnerable and protected by several international laws, subsscribed by Portugal and Spain.
