Prokaryotic and eukaryotic community structure in field and cultured microbialites from the alkaline Lake Alchichica (Mexico). [PDF]
PLoS ONE, 2011 The geomicrobiology of crater lake microbialites remains largely unknown despite their evolutionary interest due to their resemblance to some Archaean analogs in the dominance of in situ carbonate precipitation over accretion.

Effects of El Niño on the dynamics of Lake Alchichica, central Mexico [PDF]
Geofísica Internacional, 2003 Lake Alchichica is a deep, warm-monomictic lake in Puebla State, central Mexico. Water temperature, dissolved oxygen and chlorophyll a annual concentration patterns are compared under ENSO and non-ENSO conditions.

Journal of Limnology, 2022 The consistent warming of tropical lakes at all depths causes rapid development and long persistence of seasonal hypoxia in the hypolimnion, which greatly reduces the biodiversity of hypolimnetic benthic invertebrates. Full mixing of the water column in

Seasonal and Interannual Dynamics of Pelagic Rotifers in a Tropical, Saline, Deep Lake
Diversity, 2022 This is the first long-term study (monthly samples at two 4-year intervals: 1998 to 2001 and 2013 to 2016) on rotifers in a saline, deep lake. The pelagic rotifer assemblage of Lake Alchichica is simple and comprised by two species, both new and most ...

Freshwater Biology, Volume 68, Issue 11, Page 1818-1838, November 2023., 2023 Abstract Rincon de Parangueo (RP) is a Quaternary maar crater located in the Michoacan‐Guanajuato Volcanic Field in central Mexico. Like other volcanic craters in the region, the central part was occupied by an endorheic lacustrine system. As a consequence of extensive groundwater extraction, the perennial lake started a gradual desiccation process and

Short-term climatic change in lake sediments from lake Alchichica, Oriental, Mexico [PDF]
Geofísica Internacional, 2003 Reduced precipitation in central Mexico is related to ENSO events. These short-term climatic fluctuations can modify mixing-stratification patterns of lake systems, reflected in the sediments deposited at the bottom year after year.

Journal of Quaternary Science, Volume 38, Issue 5, Page 750-766, July 2023., 2023 ABSTRACT Lake Chalco, in Central Mexico, has a long diatom record which provides an excellent opportunity to document the biotic and hydrological responses of this ecosystem to orbital‐ and millennial‐scale climatic variability during the last 150 ka. Detrended correspondence analysis was used to evaluate the ecological turnover and to identify diatom ...

Nitrogen is unlikely to consistently limit primary productivity in most tropical lakes
Ecosphere, Volume 14, Issue 3, March 2023., 2023 Abstract Despite mounting evidence that tropical lakes may experience an array of phytoplankton nutrient limitation regimes, references to low‐latitude lakes being predominantly nitrogen limited remain common in the literature. To assess the current understanding of nutrient limitation regimes in tropical lakes, we performed a literature review with ...

Diversity and distribution of lacustrine diatoms along the Trans‐Mexican Volcanic Belt
Freshwater Biology, Volume 68, Issue 3, Page 391-405, March 2023., 2023 Abstract The Trans‐Mexican Volcanic Belt is recognised as a highly biodiverse zone and we present a study of diatom diversity and species distributions in its lakes. We aimed to identify diatom taxa with the highest regional occupancy, explore diversity at a regional level, identify the main variables associated with species distributions, and present ...

Journal of Quaternary Science, Volume 37, Issue 7, Page 1270-1279, October 2022., 2022 Abstract We present a palaeohydrological reconstruction of Lake Texcoco over the last 32.7 cal ka based on ostracod records consisting of two species, Candona patzcuaro and Limnocytherina axalapasco. Overall, the presence of these species suggests that Lake Texcoco was highly saline and experienced occasional desiccation periods.
