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

Comparing morphological integration patterns across groups using angular distances between PLS covariation axes

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Morphological integration describes coordinated covariation among traits arising from shared developmental, functional, or genetic interactions and plays an important role in shaping evolutionary trajectories. In geometric morphometrics, two‐block partial least squares (PLS) analysis is widely used to identify dominant axes of covariation ...
