palsa
http://purl.obolibrary.org/obo/ENVO_00000489
A low oval elevation in areas with permafrost, frequently peat bogs, where a perennial ice lens has developed within the soil. A palsa consists, similarly to a pingo, of an ice core and overlying soil materials, in case of a palsa usually boggy soil. Palsas are characteristically found in areas with discontinuous permafrost and in such areas bay be the only reliable surface evidence of permafrost. A palsa needs large quantities of water for the formation of its ice core (i.e. ice lens), which is why they frequently emerge from and are bound by boggy soils, which can store enormous quantities of water in their pores. Palsas develop particularly in moorlands and are therefore also named palsamoors.

potential evapotranspiration rate in geographic range
http://eol.org/schema/terms/PETinRange
Monthly PET (Potential Evapotranspiration Rate) within the geographic range of a taxon. Evapotranspiration (ET) is the sum of evaporation and plant transpiration from the Earth's land surface to atmosphere. Potential evapotranspiration (PET) is a representation of the environmental demand for evapotranspiration and represents the evapotranspiration rate of a short green crop, completely shading the ground, of uniform height and with adequate water status in the soil profile. It is a reflection of the energy available to evaporate water, and of the wind available to transport the water vapour from the ground up into the lower atmosphere.
