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

Diploicia christinae sp. nov. ( Ascomycota : Caliciales : Caliciaceae ), an overlooked lichen species from Bermuda

open access: yesPlant and Fungal Systematics
A crustose lichen species new to science – overlooked by previous workers – is formally described. This new species, Diploicia christinae , differs from all other species in the genus by its narrow lobes (< 1 mm) and its effuse soralia that contain ...

High‐Altitude Adaptation of Frogs (Case Study: Nanorana parkeri): From Physiological Phenotypes to AltitudeOmics

open access: yesIntegrative Zoology, EarlyView.
High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.

Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

open access: yesIntegrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

Cenozoic Tectonics Ignite Mitochondrial Codon Innovations Propelling Canid Body Size Evolution and Transcontinental Radiations

open access: yesIntegrative Zoology, EarlyView.
We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.

Introducing TropiCam‐AI: A taxonomically flexible automated classifier of Neotropical arboreal mammals and birds from camera‐trap data

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Rapid, accurate assessment of arboreal vertebrates in tropical forests remains a bottleneck for large‐scale biodiversity monitoring, due to the challenges and effort associated with traditional survey methods. To bridge this gap, arboreal camera‐trapping is emerging as a promising way to observe otherwise elusive species, opening new avenues ...
