    Abstract: 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 ≥ 1ºC/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.

    Notes: Most Mexicans live in the arid and semiarid regions that represent two-thirds of the Mexican territory, where water is scarce. Natural, as well as human, causes are favouring the degradation of Mexican lakes. There is a clear need to develop and implement sustainable water-use programmes at a catchment scale. However, the accelerated degradation rate of the Mexican lakes means that there will not be enough time to perform whole-basin evaluations to establish sustainable water-use programmes before the lakes dry up. The case of the Valle de Santiago crater-lakes clearly illustrates the declining trend that Mexican inland aquatic resources follow. Vegetation clearance, overgrazing, abatement of phreatic waters and salinization have induced severe erosion and overall desertification (land degradation) in the basin for what, it seems, a long time (i.e. prehispanic times). In this way, human activities could be provoking at least the following negative consequences: a hotter and drier local climate, water scarcity, dust storms and soil salinization. The aquatic (surface and groundwater) resources of the Valle de Santiago basin have been seriously threatened. Two of the four crater-lakes have already dried up and phreatic mantle abatement reaches up to 2.5 m per year. In spite of these facts, no sustainable water-use programme has been established yet. The future scenery of this Mexican basin looks alarmingly like many other basins in the central and northern Mexican territories.

    Notes: Mexico, with its unique northwest-southeast horn-like shape, attains its largest continental area toward the northwest. It spans more than 15° of latitude and longitude. Two-thirds of its territory lie 800 m or more above sea-level. The relief, dominated by mountains, is rugged. Climate is varied and includes arid, steppe-like, temperate and tropical lands, with a general trend of increasing aridity north of the Trans-Mexican Volcanic Belt. Such a heterogeneous physiographic-climatic scenario leads to a wide diversity of epicontinental aquatic resources, with a general trend of increasing water availability south of the Trans-Mexican Volcanic Belt. Nonetheless, Mexico scarcely holds 0.1% of the worlds’inland aquatic resources. In order to characterize, plan, and manage aquatic resources of so extensive an area, it is important to undertake a limnological regionalization. Considering the hydraulic, climatic, geographical and geological attributes of Mexico, a lake inventory and regionalization is provided to improve knowledge of the extent of Mexican limnological resources.

    Notes: Abstract Two saline crater lakes in the basin of Oriental, Puebla-Tlaxcala-Veracruz, were investigated for littoral benthic macroinvertebrates. Fifty taxa were identified with the oligochaetes, amphipods, chironomids and leeches the dominant organisms. These four taxa made up to 99 per cent in both number and biomass. Limnodrilus hoffmeisteri, Hyalella azteca, Tanypus (Apelopia) sp. and Stictochironomus sp. were the most abundant organisms. Unlike other saline lakes which have a littoral benthos dominated by chironomids, Alchichica and Atexcac were dominated by oligochaetes (70–73 per cent). The gastropod, Physa sp., was found up to a salinity of 8 g L-1; in other studies, it has been found in lower salinities. L. hoffmeisteri is also a typical inhabitant of freshwater lakes, particularly of deep waters. It was dominant in the shallow, saline waters of the two lakes studied. Salinity did not affect species richness. Alchichica, the most saline of the six crater lakes of Puebla (salinity, 7.4 g L-1), had 30 per cent more species than the freshwater lakes, and double the species number of Atexcac. It seems the main factor controlling species richness and the density and biomass of organisms in Alchichica and Atexcac is the presence of aquatic vegetation. It does this by increasing habitat heterogeneity and providing food and protection against predators.

    Notes: Abstract Carbon stable isotope ratios were determined in dominant biotic components of pelagic and littoral systems in Alchichica crater-lake. Results showed that carbon signatures were significantly different between both systems. The pelagic environment was more depleted (−26.15 to −15.14 per mille) than the littoral zone (−21.03 to −17.91 per mille). The potential source end-point in the simplified pelagic community was established to be diatomaceous phytoplankton; its predicted value was −21.7 per mille. There is a clear evidence that Nodularia does not sustain the pelagic food chain. In contrast, the highly diverse littoral community was sustained by epiphytes. No allochthonous sources seemed to influence this food web. 13C enrichment was observed along the components of both systems with fractionations of 0.8 to 1.4 per mille. The contribution of the seagrass Ruppia maritima is probably associated with the detritus pathway. Carbon source partitioning between both systems was not recorded. The δ13C in Alchichica crater-lake was more enriched than in other saline lakes and could be attributed to different salinity and CO2 concentrations among lakes.

    Notes: Abstract The effects of multiple stressors on the benthic macroinvertebrate community were monitored in Tecuitlapa Norte, a shallow, perennially-astatic, warm, mesosaline, soda-alkaline lake in Mexico. Physico-chemical and biological variables were determined monthly for one year. Tecuitlapa Norte displayed a clear seasonal environmental pattern (dry and rainy seasons). The benthic macroinvertebrate community consisted of five species: Culicoides occidentalis sonorensis Jorgensen, Ephydra hians Say, Stratiomys sp., Eristalis sp., and Limnophora sp. of which the first two were dominant and the rest scarce. C. occidentalis was the most important species numerically (76 percent of the total), while E. hians dominated the biomass (73 percent of the total). Primarily salinity and secondarily pH appear to be the most important environmental factors controlling dominance of benthic organisms in Tecuitlapa Norte. Seasonal abundance dynamics of the dominant organisms was associated with phases in their reproductive cycles: environmentally-triggered (i.e., temperature rise, water-level descent) pupation and emergence periods. We concluded that whereas physical and chemical factors (i.e., salinity, pH) exerted the primary control on benthic macroinvertebrate community composition in Tecuitlapa Norte, another assembly of variables (e.g., water-level, temperature) influenced species distribution and abundance.

    Notes: Abstract Totolcingo (El Carmen), a large and now episodically filled playa lake in the east-ernmost portion of the Mexican Plateau, filled with water in 1993. Water persisted for just one month (May). Alkaline (pH ≈ 10), saline (K25 up to 30,000μS/cm) waters, dominated by NaHCO3 and Na2CO3, characterized the lake. The fauna was depauperate. The components of the fauna wereEphydra (Hydropyrus)hians Say (ephydrid),Limnodrilus hoffmeisteri Claparède (tubificid), andBerosus sp. (Coleoptera). The species in the lake were widely dispersed and typical inhabitants of saline lakes. Possible reasons for the depauperate fauna include (a) overall physical and chemical conditions, (b) unpredictable hydrology, and (c) the short (one month) inundation period prevented colonization.
