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 ...

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

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

Journal 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).
