Evolving Strain Partitioning Driven by Multiple Plate Interaction—Paleotectonic Reconstruction of Northwestern South America During the Cenozoic

Tectonics, Volume 44, Issue 12, December 2025.
Abstract In Northwestern South America (NWSA) geodetic observations point to a consistent northeastward displacement of blocks, while the geological record shows a predominant shortening in NW‐SE direction. Such clear evidence of strain partitioning has been extensively studied in the context of two convergent plates, but not in complex tectonic area ...

Novel Insights Into the Genetic Population Connectivity of Transient Whale Sharks (Rhincodon typus) in Pacific Panama Provide Crucial Data for Conservation Efforts

Frontiers in Marine Science, 2021
The whale shark (Rhincodon typus) is an endangered and highly migratory species, of which solitary individuals or aggregations are observed in oceans worldwide and for which conservation efforts are hindered by a lack of comprehensive data on genetic ...

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

Basin 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 ...

Una lista anotada de las aves de la isla Malpelo

Ornitología Colombiana, 2021
La avifauna de Malpelo ha sido poco estudiada porque la Isla es remota, de difícil acceso y estuvo deshabitada hasta 1986. Pese a que existen registros de aves publicados desde finales del siglo XIX, casi todos los estudios han consistido en anotaciones esporádicas sobre la fauna terrestre.

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

Aquatic 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 ...

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

Tectonics, 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.

Toward Sustainable Biocultural Ecotourism: An Integrated Spatial Analysis of Cultural and Biodiversity Richness in Colombia

People and Nature, Volume 7, Issue 1, Page 194-214, January 2025.
Abstract Ecotourism plays a vital role in both economic development and depending on the scale, it can also aid environmental conservation. Ecotourism planning often considers culture‐based and nature‐based tourism separately, failing to recognize the synergies between them, with the potential to market locations as biocultural destinations.

New photographic records of eight marine fishes from the Galápagos Islands, including three first records for the Eastern Tropical Pacific [PDF]

Check List
We provide photographic evidence for eight fish species from five families, not previously seen within the Galápagos Marine Reserve. Four species are native to the Central Tropical Pacific and likely arrived during recent El Niño ...

Zircon Xenocrysts From Easter Island (Rapa Nui) Reveal Hotspot Activity Since the Middle Jurassic

AGU Advances, Volume 5, Issue 5, October 2024.
Abstract We report the finding of mantle‐derived zircon grains retrieved from red soils, regoliths, and beach sands from Easter Island, that are much older than the island volcanism (0–2.5 Ma) and its underlying lithosphere (Pliocene, 3–4.8 Ma). A large population of 0–165 Ma old zircons have coherent oxygen (δ18O 3.8–5.9‰) and hafnium (εHf(t)+3.5–+12 ...
