“…The thermocline set-up with slight temperature differences-tenths of degrees Celsius-relative to depth. In the case of Lake Zempoala, the maximum depth of 5 m still allows the thermocline formation in the upper meters (García-Rodríguez & Tavera, 2002); while in Zirahuén fluctuates between 10 and 15 m and in Alchichica between 20 and 30 m. The study case of Lake Pátzcuaro shows annual temperature differences of some 10°C, a significant seasonal variation in contrast to African waters (Melack, 1979), which register day-to-day and dial variations in water temperatures slightly less than seasonal variations (2.2-3.2°C).…”

The document herewith deals with the geography, geology, and climate of the Mexican territory as the basis to further explain the development of Limnology as a science in this country. An early knowledge started with the Aztecs, with evidence of practical solutions for a life within a lake. After the conquest of the American territories by the Spaniards, the exploration of the new territories provided the main source of information relative to natural resources. In 1938, the Mexican government established the Estación Limnológica de Pátzcuaro and the pioneer studies appeared under the name of Spanish scientists not only here but also at the Universidad Nacional Autónoma de México and the Instituto Politécnico Nacional. During the 1970s, the participation of Mexican limnologists began and the attempt to build-up a conceptual framework in its own for lakes, reservoirs, and rivers. This article outlines the main limnological characteristics of Mexican water bodies, highlights the peculiarities of a transitional zone between the tropics and subtropics, and describes the government structure for management and administration. A fast development in this area of knowledge got underway with the creation of the Asociación Mexicana de Limnología in 1997 and the collaboration with international counterparts.

“…Most of the terrain in this region is mountainous (>2 000masl, average temperature is 15°C), as a primarily product of Quaternary volcanism. Abundant aquatic ecosystems of tectonic and volcanic origin are found within the TMVB (Davies et al, 2002;García-Rodríguez, & Tavera, 2002), and lakes dammed by lava flows, or by large scale rock avalanches. Numerous dams (man-made and natural) are found in the region as well (Conserva, & Byrne, 2002;Suter, 2004; de la Lanza-Espino, Gómez-Rodríguez, Islas Islas, Escalante Richards, & Hernández Pulido, 2011).…”

Abstract:The ostracode fauna of the neartic-neotropical transitional zone has remained poorly known until this study. Ten ostracode species inhabit ten highland lakes (five maar lakes (phreatic/phreato-magmatic explosion origin), one volcanic-tectonic lake, three natural dams and one man-made dam) in East-central Mexico. Surface sediments from the deepest part and the littoral zone from all studied lakes were collected. Environmental variables (pH, temperature, dissolved oxygen, conductivity, TDS) were measured in situ and parallel water samples for chemical analysis were collected for habitat description. Widely distributed species in the study area (≥5 lakes) include Cypridopsis vidua, Darwinula stevensoni and Eucandona cf. patzcuaro. Limnocytherina axalapasco is an endemic species and was collected in three maar lakes and in one man-made dam. Rare species included: Chlamydotheca arcuata?, Fabaeformiscandona acuminata?, Ilyocypris gibba?, Limnocythere friabilis?, Potamocypris smaragdina? and Potamocypris unicaudata?. Highest species richness (6 spp.) was found in the large and shallow Lake Metztitlán (2.6km 2 , 5.5m deep), with the lake water type HCO 3 ->>SO 4 2->Cl ---Ca 2+ >Na + >Mg 2+ . The rest of studied lakes (<63m, <27km 2 ) had not more than three species. For instance, only two ostracode species were collected in Lake Alchichica, which is the largest, deepest and most saline studied maar lake. Rev. Biol. Trop. 63 (2): 401-425. Epub 2015 June 01.

The present work reviews our current understanding of the limnology of Lake Zirahue´n and extends this knowledge through an analysis of the phytoplankton, illustrating phenomena that typify monomictic tropical lakes. The analysis reinforces the postulate that atelomixis determines the variation in phytoplankton composition of deep tropical lakes with a monomictic mixing regime. Similarly, it is proposed that an incomplete or partial atelomixis, generating a highly dynamic mixing layer, is a force that possibly drives the selection of algal groups, like the Desmidiaceae, with a high surface area to volume ratio. These organisms, characteristic of tropical lakes, though found in the deep epilimnetic layer, receive sufficient irradiance to support their high photosynthetic rate; their high population density survive thanks to a constant supply of nutrients. Lake Zirahue´n is a particularly relevant case for Mexico, since the low calcium concentration and the trophic level of the lake provide an explanation for the otherwise uncommon presence of desmids in other Mexican lakes, even in lakes that exhibit atelomictic phenomena.
