Influence of environmental and biological factors on mercury accumulation in fish from the Atrato River Basin, Colombia

open access: yesEnvironmental Pollution
Understanding variations in total mercury (T-Hg) levels in fish is crucial for protecting aquatic biota and human health. This article evaluates the influence of environmental factors (temperature, pH) and biological variables (feeding habits, trophic level, total length, total weight), on T-Hg concentrations in fish from the Atrato River basin ...

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

Aquatic insects associated with macrophytes in wetlands of the middle basin of Atrato River, Chocó - Colombia

open access: yesRevista U.D.C.A Actualidad & Divulgación Científica
Aquatic macrophytes play an important role in lentic systems, since they constitute the particular habitat of several groups of aquatic insects and play a fundamental role in structuring their communities. The objective of this study was to contribute to the knowledge of the aquatic entomofauna associated with macrophytes in wetlands of the middle ...

Hemibrycon rafaelense sp. n. (Characiformes, Characidae), una nueva especie del alto Cauca, con claves de identificación para las especies colombianas [PDF]

open access: yes, 2008
A new fish species of Hemibrycon is described from the San Rafael River, upper Cauca River, Colombia. H. rafaelense canbe distinguished from other species of the genus by the number of cusps on the teeth in the internal premaxilla row (3-5 vs. 5-7 except

What is (the) matter with climate litigation? Law, nature, and the limits of legal technique

open access: yesJournal of Law and Society, Volume 52, Issue 2, Page 159-180, June 2025.
Abstract This article examines how nature is mediated by law in climate cases. In the Federal Court of Australia decision in Minister for the Environment v. Sharma (2022), the court applied a narrow definition of ‘matter of law’ (justiciability), and thereby negated ‘matter in law’ (such as carbon dioxide and ecological destruction).

Detection of Linkage Between Solar and Lunar Cycles and Runoff of the World's Large Rivers

open access: yesEarth and Space Science, Volume 6, Issue 6, Page 914-930, June 2019., 2019
Abstract It is an ongoing concern that global hydrological cycle can be likely intensified under context of climate change and anthropogenic actions. Here, our results show that the solar and lunar periodic motions (SLPMs) have substantial impact on the runoff of the world's large rivers. We estimate that SLPMs can produce a change of the world's large

Implementing Nature\u27s Rights in Colombia: The Arato and Amazon Experiences [PDF]

open access: yes, 2023
Nature\u27s rights approaches are being developed as an alternative legal means to enable justice for nature and, oftentimes, humans, too. This study examines Colombia\u27s two seminal court-ordered nature\u27s rights approaches which recognize ...

Streamflow Variability in Colombian Pacific Basins and Their Teleconnections with Climate Indices [PDF]

open access: yes, 2020
[EN] Oceanic-atmospheric phenomena of different time scales concurrently might affect the streamflow in several basins around the world. The Atrato River Basin (ARB) and Pa-Ha River Basin (PRB) of the Colombian Pacific region are examples of such basins.

Linking Landslide Patterns to Transient Landscapes in the Northern Colombian Andes

open access: yesJournal of Geophysical Research: Earth Surface, Volume 130, Issue 3, March 2025.
Abstract Landslides are among the most recognizable evidence of hillslope erosion in tectonically active mountains. Yet, how much of the distribution of landslides of different ages relates to, or is inherited from, the pattern of topographic metrics of landscape evolution remains partially unresolved, and especially so in tropical areas.

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.
