Fish community structure dynamics in cenotes of the Biosphere Reserve of Sian Ka’an, Yucatán Peninsula, Mexico

Revista Mexicana de Biodiversidad, 2013
Cenotes are permanent aquatic systems formed by geomorphologic processes (karst), located in the Yucatán Peninsula. Many of these oligotrophic systems are connected superficially to wetlands during the wet season. We describe the fish community structure

La capacidad de carga psicosocial del turista: instrumento de medición para el desarrollo sostenible en la turistificación de los cenotes

Cuadernos de Turismo, 2019
La capacidad de carga psicosocial ha demostrado ser un instrumento efectivo para establecer números máximos de personas que un turista está dispuesto a ver simultáneamente en espacios naturales. Aunque, ha sido muy aplicado en parques nacionales de EEUU,

Late Pleistocene to Holocene sedimentation in the Great Blue Hole (Lighthouse Reef, Belize): Results from a 30 m long core

The Depositional Record, Volume 11, Issue 5, Page 1376-1398, November 2025.
A 30 m long sedimentary succession at the bottom of the Belize Blue Hole represents terrestrial cenote (12.5–7.2 ka BP), restricted marine swamp (7.2–5.7 ka BP) and fully marine lagoonal phases (5.7–0 ka BP) on Lighthouse Reef carbonate platform. Post‐glacial and Holocene sea‐level rise largely controlled the sedimentological, faunal and floral changes

Cenotes – Lakes of the Yucatan Peninsula (Mexico)

Studia Quaternaria, 2015
Abstract Cenote lakes are natural sinkholes or depressions resulting from the collapse of limestone bedrock exposing the groundwater underneath. Thousands of such lakes are particularly encountered on the Yucatan Peninsula (Mexico). These lakes were of great significance for the Maya culture as important religious places and primary source of ...

Evolutionary history of Middle American Rhamdia (Siluriformes: Heptapteridae) inferred from comparative mitogenomic data: Insights on historical biogeography and cave colonization in the group

Journal of Systematics and Evolution, Volume 63, Issue 6, Page 1501-1518, November 2025.
Investigating the systematics and biogeography of Neotropical catfishes of the genus Rhamdia refined phylogenetic hypotheses, including deep paraphyly of Rhamdia laticauda, supported northward dispersal catalyzed by emergence of the Panamanian Isthmus and imply that cave colonization is widespread, convergent, and recent, with established cave‐dwelling

Analyzing Land Use and Hydrological Influences on Metals and Nutrients Recorded in an Unconfined Coastal Karstic Aquifer, Yucatán Peninsula, México

Journal of Marine Science and Engineering
Unconfined coastal karst aquifers are highly susceptible to contamination from anthropogenic activities, particularly in regions lacking adequate wastewater treatment. Their open hydrological structure facilitates the input and dispersion of contaminants

Standardizing Visualization in Ancient Maya Lidar Research: Techniques, Challenges and Recommendations

Archaeological Prospection, Volume 32, Issue 4, Page 967-988, October/December 2025.
ABSTRACT Airborne laser scanning (ALS, lidar) has become a key method for studying ancient Maya landscapes, offering unprecedented visibility of anthropogenic terrain modifications in densely forested environments. Despite this progress, the visualization of elevation data remains understandardized, with many researchers relying on ad hoc or ...

The trophic role of cave shrimps of the genus Typhlatya seen through stable isotope eyes [PDF]

Subterranean Biology
With the aim of describing the isotopic niche of the anchialine shrimps of the genus Typhlatya from the Yucatan Peninsula (YP) we analyze a dataset that includes three of the four species present in the region using published and new δ13C and δ15N values.

Yucatan Hurricane Activity Highlights Common Era Tropical Cyclone Dipole

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract Tropical cyclone (TC) impacts along the western Atlantic and Caribbean margin are not spatially uniform. Proxy based reconstructions of Common Era TC activity highlight this non‐uniform distribution at centennial‐millennial timescales. However, the sparse geographic scope of these reconstructions impedes our assessment of TC landfalls across ...
