Patterns and Drivers of Tree Species Accumulation in Three Biodiversity Hotspots of Northwestern South America

Journal of Biogeography, Volume 52, Issue 12, December 2025.
ABSTRACT Aim This study aims to understand the relative importance of climatic anomalies since the Last Glacial Maximum (LGM) and regional biogeographic (evolutionary) features as drivers of local and regional tree species accumulation across three neotropical biodiversity hotspots in northwestern South America (Northwestern Amazon, Northern Andes and ...

The Link Between Range Size, Niche Specialisation and Diversification in One of the Most Successful Avian Radiations, the New World Flycatchers (Tyrannoidea)

Journal of Biogeography, Volume 52, Issue 11, November 2025.
ABSTRACT Aim Range size constitutes a fundamental characteristic of every species and is commonly believed to influence diversification rates. This relationship is potentially dependent on the mode of speciation and other intrinsic factors, including geographic setting and species attributes. Yet, not only the size of the geographic range, but also the

Nuevas localidades fosilíferas en la cordillera central de colombia

, 1962
Si descrivono nuove località fossilifere della Cordigliera Centrale.  I fossili raccolti appartengono all' Aptiano ed all' Albiano medio. Tra i due piani é stata riconosciuta per la prima volta nella Cordigliera Centrale una importante discordanza (già nota nella Orientale), indizio di una importante fase tettonica con la quale é connessa la messa in ...

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
