Abstract Isotope hydrological studies to understand groundwater‐surface water interactions in tropical, high‐elevation catchments are limited. These interactions are important in controlling lake water residence time, aqueous biogeochemistry, and water availability for downstream communities and ecosystems. To better comprehend the complexity of spatio‐

ABSTRACT Lake Van, the world's largest alkaline lake, hosts some of the largest microbialite towers worldwide, which are considered as modern analogues of ancient stromatolites. This study investigates the links between microbialite evolution, geology, climate and hydrology, and the role of biotic and abiotic processes in microbialite growth and ...

Ciliate food vacuole content and bacterial community composition in the warm-monomictic crater Lake Alchichica, México [PDF]
To evaluate trophic relationships between ciliates and bacterioplankton during the stratification period in a lake, samples from three different layers [the upper part of the metalimnion (UM), the base of the metalimnion (BM) and the hypolimnion] were studied. The autotrophic picoplankton numbers, phylogenetic composition of heterotrophic picoplankton (

Planktonic bloom-forming Nodularia in the saline Lake Alchichica, Mexico [PDF]
Lake Alchichica displays a characteristic cyanobacterial bloom associated with the onset of the stratification period. It mostly consists of the nitrogen-fixing cyanobacterium Nodularia spumigena.

Pollen determination from sediment core of Lake Alchichica in Mexico
The pollen samples were collected from a 57-cm-long sediment core retrieved from Lake Alchichica (19° 24' 38 N, 97° 24' 14 W, 2322 masl) at a water depth of ~ 60 m using a Uwitec® coring device equipped with a 9-cm coring tube. A total of 39 wet sediment
