Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

open access: yesIntegrative Zoology, EarlyView.
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

Lagomorpha as a Model Morphological System

open access: yesFrontiers in Ecology and Evolution, 2021
Due to their global distribution, invasive history, and unique characteristics, European rabbits are recognizable almost anywhere on our planet. Although they are members of a much larger group of living and extinct mammals [Mammalia, Lagomorpha (rabbits,

Differences in Dietary Composition and Interspecific Competition Among Large Carnivores on the Qinghai–Xizang Plateau

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
This study elucidated the mechanisms underlying regional coexistence among the snow leopard (Panthera uncia), wolf (Canis lupus), and brown bear (Ursus arctos) through the analysis of their trophic niches. The findings provide a scientific foundation for further investigation into the mechanisms that maintain carnivore communities in high‐altitude ...

Effect of chronic traffic noise on behavior and physiology of plateau pikas (Ochotona curzoniae)

open access: yesFrontiers in Ecology and Evolution, 2022
During the last two decades, numerous studies have shown the effects of traffic noise on animal vocal communication. However, studies on the influences of traffic noise on wildlife behavior and physiology are scarce.

Simulated soundscapes and transfer learning boost the performance of acoustic classifiers under data scarcity

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 2, Page 322-338, February 2026.
Abstract The biodiversity crisis necessitates spatially extensive methods to monitor multiple taxonomic groups for evidence of change in response to evolving environmental conditions. Programs that combine passive acoustic monitoring and machine learning are increasingly used to meet this need. These methods require large, annotated datasets, which are

Environmental DNA (eDNA) Technology in Biodiversity and Ecosystem Health Research: Advances and Prospects

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
This review synthesizes over 15 years of advancements in eDNA technology by systematizing standardized guidelines for sampling, extraction, and bioinformatics, thereby enhancing the reproducibility of eDNA‐based research. It highlights eDNA's transformative role in noninvasively detecting rare, endangered, and invasive species, as well as its value in ...

A homotetrameric hemoglobin expressed in alveolar epithelial cells increases blood oxygenation in high-altitude plateau pika (Ochotona curzoniae)

open access: yesCell Reports, 2022
Summary: The plateau pika (Ochotona curzoniae) is native to the Qinghai-Tibet Plateau. In this study, the gene that encodes a heme-binding protein in the pulmonary surfactant (PS) of the pika is identified. The protein is a homotetrameric hemoglobin (δ4)

Sampling a pika's pantry: Temporal shifts in nutritional quality and winter preservation of American pika food caches

open access: yesEcosphere, 2023
Climate change is increasing temperature, decreasing precipitation, and increasing atmospheric CO2 concentrations in many ecosystems. As atmospheric carbon rises, plants may increase carbon‐based defenses, such as phenolics, thereby potentially affecting
