Long term picoplankton dynamics in a warm-monomictic, tropical high altitude lake

open access: yesJournal of Limnology, 2009
Long term analyses of the microbial loop, centred on the picoplankton dynamics, were carried out over a five-year (1998 to 2002) period in Lake Alchichica (Puebla, Mexico), a high altitude tropical athalassohaline lake.

Spirostomum teres: A Long Term Study of an Anoxic-Hypolimnion Population Feeding upon Photosynthesizing Microorganisms

open access: yesActa Protozoologica, 2020
The pelagic / anoxic hypolimnion population of Spirostomum teres was investigated as a part of the long-term ciliates’ monitoring (2003–2016) in an oligo- to mesotrophic monomictic hyposaline crater ...

Exploring Biogeochemistry and Microbial Diversity of Extant Microbialites in Mexico and Cuba [PDF]

open access: yes, 2018
Microbialites are modern analogs of ancient microbial consortia that date as far back as the Archaean Eon. Microbialites have contributed to the geochemical history of our planet through their diverse metabolic capacities that mediate mineral ...

Late Pleistocene–Holocene environmental fluctuations of southern Chihuahua Desert, Mexico

open access: yesJournal of Quaternary Science, Volume 40, Issue 4, Page 634-644, May 2025.
ABSTRACT Paleoenvironmental reconstructions from the Mexican Chihuahua Desert based on biological proxies are scarce, creating a gap in our understanding of the ecological responses to climate change in this water‐scarce region. Here, we present a paleoenvironmental reconstruction based on geochemical data and biological proxies such as ostracods and ...

Calcium carbonate and phosphorus interactions in inland waters

open access: yesLimnology and Oceanography Letters, Volume 10, Issue 2, Page 158-178, April 2025.
Abstract Phosphorus, an element essential to all life, is impacted by calcium carbonate (CaCO3) co‐precipitation and dissolution dynamics across aquatic ecosystems. Changes to climate, hydrology, and eutrophication, coupled with differences in terminology related to naming CaCO3‐producing ecosystems (i.e., chalk, carbonate, karst, travertine), point to

Untangling the Primary Biotic and Abiotic Controls on Oxygen, Inorganic and Organic Carbon Isotope Signals in Modern Microbialites

open access: yesGeobiology, Volume 23, Issue 1, January/February 2025.
ABSTRACT Microbialites are organo‐sedimentary structures formed throughout most of the Earth history, over a wide range of geological contexts, and under a multitude of environmental conditions affecting their composition. The carbon and oxygen isotope records of carbonates, which are most often their main constituents, have been used as a widespread ...

Tracing Groundwater‐Surface Water Interactions in a Volcanic Maar Lake Using Stable Isotopes and 222Rn

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 129, Issue 12, December 2024.
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‐
