Temperate forests 

Temperate forests are largely found between 40° and 60° N of the equator. 

Temperate rain forest (Evergreen): Temperatures are a little cooler, 5–25°C on average, and winters are mild, but there is abundant rainfall, usually exceeding 200 cm a year

Temperate Deciduous Forest (lose their leaves in winter):  Temperatures fall below freezing each winter but not usually below –12°C, and annual rainfall is generally between 75 and 200 cm. Soils are rich in organic and inorganic nutrients, and quite fertile.

Second possible mechanisms for neoblast specification during regeneration:

Multipotent progenitor cells are positioned throughout the planarian with their lineages specified based on their position. These divide and produce postmitotic blastema cells that differentiate into their specified fates.
