Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Animal‐Mediated Dispersal and Clonal Growth Drive Prunus cerasus Invasion in Andean Temperate Forest

open access: yesIntegrative Zoology, EarlyView.
Prunus cerasus reproduces by clonality and by seed dispersal and germination. P. cerasus is invading Patagonian protected areas. The relative relevance of germination and clonal reproduction changes along the time of P. cerasus arrival at a site. Seed dispersal by foxes is primarily responsible for the spread of P. cerasus to new areas.

AlpIce‐1: a database of geochronological and geomorphological constraints on Alps‐wide palaeoglacier fluctuations between the Last Glacial Maximum and the Holocene

open access: yesBoreas, EarlyView.
The AlpIce‐1 database is the first compilation of published geomorphological and geochronological markers constraining build‐up, culmination and decay of glaciers from the Last Glacial Maximum through the Holocene across the entire European Alps. AlpIce‐1 integrates more than 4200 surface‐exposure and radiocarbon ages, homogenized, quality controlled ...
