Ecological studies on algal communities from Tierra del Fuego peat bogs

Microalgal communities from seven water hollows have been studied in six peat bogs located in the southwest of the Tierra del Fuego Province (Argentina). The evolution of these systems towards terrestrial conditions includes a gradual increase in conductivity and decrease in pH along a gradient from...

description Microalgal communities from seven water hollows have been studied in six peat bogs located in the southwest of the Tierra del Fuego Province (Argentina).
