Latest Cretaceous to Cenozoic Exhumation Patterns in the Northern Andes From the Sedimentary Provenance Record on the Broken Retro‐Foreland Putumayo Basin

open access: yesBasin Research, Volume 37, Issue 3, May/June 2025.
(A) Tectonic model of the Putumayo Basin showing the several collisional events that triggered the inversion of preexistent Jurassic rift sequences during the Upper Cretaceous and their influence in the provenance sources from the synorogenic deposits. Brown arrows suggest Amazonian and Putumayo basement sources, dark green arrows suggest a provenance ...

Morphology, ethology, new records, and ecological niche modeling for Hydromorphus and Tretanorhinus (Squamata, Colubridae) in Panama [PDF]

open access: yesHerpetozoa
The genera Hydromorphus and Tretanorhinus (Colubridae) comprise uncommon, poorly studied aquatic snakes, largely because of their nocturnal and aquatic habits. In Panama, four species have been recorded: Hydromorphus concolor, H.

A Review of the Status of Sharks, Rays and Chimaeras of Panama to Guide Research and Conservation

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 4, April 2025.
ABSTRACT Chondrichthyan fishes (sharks, rays and chimaeras) are a group of high conservation concern globally. Species are impacted by varying threats, although fishing pressure is the primary stressor causing population declines. Panama comprises both Pacific and Caribbean coastlines with a diversity of estuarine and marine habitats supporting small ...

Phytoplankton Dynamics and Environmental Variability in the Eastern Equatorial Pacific Over Glacial‐Interglacial Timescales

open access: yesPaleoceanography and Paleoclimatology, Volume 40, Issue 4, April 2025.
Abstract The Eastern Equatorial Pacific serves as a critical region for understanding the interplay between phytoplankton dynamics and global carbon cycling over glacial‐interglacial timescales. This study investigates the calcareous nannofossils from sediment core MV1014‐02‐17JC (17JC) and previously published diatom assemblage data from core MD02 ...

The Role of Transpressional Tectonics, Volcanism, and Fluvial Processes on the Oligocene to Pliocene Evolution of Intermontane Basins of the Western Colombian Andes

open access: yesTectonics, Volume 44, Issue 3, March 2025.
Abstract We use new and published detrital zircon U‐Pb data (n > 10,000) from Oligocene‐Pliocene strata of intermontane basins of the western Colombian Andes and surrounding regions to study the evolution of sedimentary systems during the transition from arc collision/accretion to subduction.
