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

Integrative 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

Contrastive ecoacoustic indices: Large‐scale global soundscape characterization with contrastive inference

Methods in Ecology and Evolution, EarlyView.
Abstract Ecoacoustics mainly aims at monitoring soundscapes by means of non‐invasive protocols. Despite the widespread adoption of machine and deep learning techniques, existing ecoacoustic models predominantly rely on supervised learning and, consequently, face two primary limitations: (1) the necessity of annotated data; and (2) the restriction to ...

16S/18S metabarcoding versus culture for aetiological assessment in infectious keratitis: A prospective paired‐sample study

Acta Ophthalmologica, EarlyView.
Abstract Purpose Infectious keratitis (IK) is a vision‐threatening condition with diverse microbial aetiologies, yet conventional culture‐based diagnostics often have limited sensitivity. We investigated whether 16S/18S rRNA amplicon‐based next‐generation sequencing (NGS) can enhance aetiological assessment when used alongside standard microbiological ...

Behavioral interventions to reduce demand for threatened freshwater turtles as pets

Conservation Biology, EarlyView.
Abstract Growing demand for freshwater turtles as pets has fueled illegal trade and accelerated wild population declines, underscoring the need for theory‐based demand‐reduction interventions. We conducted a three‐part randomized controlled trial with active turtle keepers (n = 1800) in China to test conservation‐ and legality‐framed messages by ...
