The book provides a comprehensive account of a tropical lake, Alchichica, considering that tropical limnology is by far less well-understood than temperate. Many of the well-known temperate limnology paradigms do not apply in tropical limnology, such as the ≥ 1�C/m thermocline concept, or the role of phosphorous as limiting nutrient. Lake Alchichica is - most likely - the best limnologically known Mexican lake up to date. Twenty years of continuous monitoring has led us to understand this deep, warm monomictic lake. The peculiar chemical composition of this saline lake - sodium-alkaline with high concentration in magnesium waters, and groundwater-fed - led to the formation of its unique stromatolite ring that has become world-famous, studied by scientists from various countries. From a biological point of view, this relatively small maar lake displays a low species richness, but surprisingly is plentiful in microendemic species for a recently-formed lake (12,000 years old, at the onset of Holocene Epoch), eleven of which already described, with more to come. Researchers and students interested in tropical limnology, extreme ecosystems, evolutionary biology, and microbiology will find this book a must-read.
