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

open access: yesFront Microbiol, 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 ...

Reappraising the eruptive history of the Alchichica Maar Volcano (Mexico) based on Sr–Nd isotopes: Understanding the role of the magma source region on the growth of small-volume volcanoes

open access: yesSolid Earth Sciences
Alchichica Maar is in the eastern sector of the Trans-Mexican Volcanic Belt, where volcanics range from basalts to rhyolites, with 87Sr/86Sr and 143Nd/144Nd values between 0.70293 to 0.70447 (εSr = −21.1 to −4.5) and 0.512733 to 0.512949 (εNd = +3.4 to ...

Planktonic bloom-forming Nodularia in the saline Lake Alchichica, Mexico [PDF]

open access: yes, 2009
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.

Rapid formation of mature microbialites in Lake Alchichica, Mexico [PDF]

open access: yesEnvironmental Microbiology Reports, 2021
Summary Microbialites are emblematic sedimentary rocks formed by phylogenetically and metabolically complex microbial communities thriving under specific physicochemical conditions. Most microbialites are photosynthesis‐based ecosystems frequently formed by carbonates, thereby capturing inorganic carbon in the ...

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

open access: yesDiversity, 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 ...

Geomicrobiology of the Rincon de Parangueo maar crater: Exploring the link between an evolving extreme environment and its potential metabolic diversity

open access: yesFreshwater 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

Response of diatom assemblages to orbital‐ and millennial‐scale climatic variability since the penultimate glacial maximum in the northern limit of the Neotropics

open access: yesJournal 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

open access: yesEcosphere, 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 ...

A subjective global checklist of the extant non-marine Ostracoda (Crustacea) [PDF]

open access: yes, 2019
We present an updated, subjective list of the extant, non-marine ostracod genera and species of the world, with their distributions in the major zoogeographical regions, as well as a list of the genera in their present hierarchical taxonomic positions ...
