Vocalizations Reveal Species Differences in Endangered Lion Tamarins (Primates, Callitrichidae)

open access: yesAmerican Journal of Primatology, Volume 88, Issue 1, January 2026.
Spectral parameters of vocalizations distinguish lion tamarin species. Peak frequency, center frequency, and frequency at 5% and 95% were the most informative measures for separating species, with the trill being the vocalization that showed the most differences, and Leontopithecus caissara being the most distinct species of all.

Solution‐Processed Magnesium Oxide Buffer Layer for Improved Stability of CsPbI2Br Perovskite Solar Cells

open access: yesSolar RRL, Volume 10, Issue 1, January 2026.
An interfacial engineering strategy incorporating magnesium oxide (MgO) between the ZnO electron transport layer and CsPbI2Br is demonstrated. This approach yields perovskite solar cells with improved film morphology, charge mobility, and stability. Proton‐irradiated MgO‐incorporated devices retain their performance after 11 weeks, whereas the control ...

Multidimensional Fingerprinting Strategy for the Quality Evaluation of Sporoderm‐Broken Ganoderma lucidum Spores

open access: yesJournal of Food Quality, Volume 2026, Issue 1, 2026.
It remains challenging to improve the quality standard system of Traditional Chinese Medicine (TCM) for TCM development. Currently, it is urgently needed to develop an integrated, effective, and scientific approach to improve the efficacy, safety, and quality consistency of sporoderm‐broken spores of Ganoderma lucidum (SSGL).

Ecological Exposure History Shapes Giraffe Vigilance Responses to Anthropogenic Noise: A Multisite Playback Experiment

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Understanding how animals respond to anthropogenic disturbance is essential for predicting the impacts of human activity on wildlife behavior and persistence. As noise increasingly alters sensory landscapes across ecosystems, it can influence how animals detect threats and assess risk.
