Development and evaluation of pupal color‐based genetic sexing strains in Anastrepha obliqua (Diptera: Tephritidae)

open access: yesInsect Science, EarlyView.
Two spontaneous mutations in pupae of the West Indian fruit fly Anastrepha obliqua, named bp and sp, were isolated and studied. The bp mutation was selected, and using two types of Y‐autosoma l translocation inducers and an appropriate crossing scheme, two genetically sexed strains based on pupa l color were developed for the first time in this species,

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

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.
