altitude, with distinctive geological, climatic and geomorphological characteristics which
play an important role on local surface and groundwater resources. Serra da Estrela was
formed by Alpine tectonic activity along with glacial and periglacial processes. In this
mountain is found the largest set of lakes and ponds of glacial origin of Portugal, specially
above 1300 m ]]> 2019-02-03 11:54:47 UTC https://padlet.com/elsa_salzedas/az8tojimme9b/wish/327045552 Alpine Ponds elsa_salzedas https://padlet.com/elsa_salzedas/az8tojimme9b/wish/327047999 Alpine ponds are small, natural, low-depth bodies of water that form in depressions in the soil , usually of glacial origin, occurring along the landscape, specifically in mountains and at high altitudes, which allows temporary or permanent retention of Water.
Ponds trophic state was variable over months but, in general, these are oligotrophic and mesotrophic for chlorophyll a and phosphorus content, respectively.
