Benthic species assemblages change through a freshwater cavern-type cenote in the Yucatán Peninsula, Mexico [PDF]

open access: yesSubterranean Biology, 2022
We studied benthic assemblages through X-Batún, a continental freshwater cenote and its associated submerged cave located in San Antonio Mulix (Yucatán, Mexico). Using cave diving techniques, we collected sediment samples at four zones of the system.

Cenote-Taker 2 democratizes virus discovery and sequence annotation [PDF]

open access: yesVirus Evolution, 2021
Abstract Viruses, despite their great abundance and significance in biological systems, remain largely mysterious. Indeed, the vast majority of the perhaps hundreds of millions of viral species on the planet remain undiscovered. Additionally, many viruses deposited in central databases like GenBank and RefSeq are littered with genes ...

Distinctive prokaryotic microbiomes in sympatric plant roots from a Yucatan cenote [PDF]

open access: yesBMC Research Notes, 2021
Objective Cenotes are flooded caves in Mexico’s Yucatan peninsula. Many cenotes are interconnected in an underground network of pools and streams forming a vast belowground aquifer across most of the peninsula.

Trophic ecology in an anchialine cave: A stable isotope study. [PDF]

open access: yesPLoS ONE
The analysis of carbon and nitrogen stable isotopes (δ13C and δ15N) has been widely used in ecology since it allows to identify the circulation of energy in a trophic network. The anchialine ecosystem is one of the less explored aquatic ecosystems in the
