Candona alchichica (Podocopida: Candonidae), a new ostracod species from saline, tropical Lake Alchichica, Mexico [PDF]
In North America, most species of the Candonidae family belong to the genus Candona. These species are frequently found in freshwater ecosystems and in sediment sequences, which makes them valuable tools for paleoenvironmental reconstructions.

Habitat expansion of a tropical chironomid by seasonal alternation in use of littoral and profundal zones [PDF]
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

Chironomus alchichica sp. n. (Diptera: Chironomidae) from Lake Alchichica, Mexico
Morphological analysis of all developmental stages (except female), mitochondrial DNA sequences from cytochrome c oxidase subunit I (cox1) and cytological analysis of the polytene chromosomes were used to describe a new species of Chironomus found in the

Deposition, burial and sequestration of carbon in an oligotrophic, tropical lake [PDF]
The amount of biogenic carbon that may be deposited, buried and eventually preserved (sequestered) in the sediments of a tropical, oligotrophic lake, was evaluated based on i) the temporal variation of the particulate organic carbon (POC) concentration ...

Short-term climatic change in lake sediments from lake Alchichica, Oriental, Mexico [PDF]
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.

Seasonal and Interannual Dynamics of Pelagic Rotifers in a Tropical, Saline, Deep Lake
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 ...
