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

open access: yesThe 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

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

open access: yesJournal 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

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

open access: yesJournal 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

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

open access: yesArchaeological 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]

open access: yesSubterranean 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

open access: yesGeophysical 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 ...
