Dynamics of Suitable Habitats for Typical Predators and Prey on the Qinghai‐Tibet Plateau Driven by Climate Change: A Case Study of Tibetan Fox, Red Fox, and Plateau Pika [PDF]

Ecology and Evolution
The Qinghai‐Tibet Plateau (QTP) is a biodiversity hotspot highly sensitive to global climate change. The Tibetan fox (Vulpes ferrilata), red fox (V.

Metagenomic Comparisons between Soft and Hard Feces of Plateau Pikas (Ochotona curzoniae) [PDF]

Animals, 2022
The division of hard and soft feces is an effective digestion strategy in the order Lagomorpha. Although previous studies have reported that hard and soft feces differ in morphology and component, the discrepancy in the microbiome remains unclear. This study explored the microbiomes of hard and soft feces in plateau pikas by sequencing the V3 and V4 ...

Risk assessment in the plateau pika (Ochotona curzoniae): intensity of behavioral response differs with predator species. [PDF]

BMC Ecol, 2020
AbstractBackgroundThe ability of a prey species to assess the risk that a predator poses can have important fitness advantages for the prey species. To better understand predator–prey interactions, more species need to be observed to determine how prey behavioral responses differ in intensity when approached by different types of predators. The plateau

Species-Level Taxonomic Characterization of Uncultured Core Gut Microbiota of Plateau Pika

Microbiology Spectrum, 2023
Rarely has the vast diversity of bacteria on Earth been profiled, particularly on inaccessible plateaus. These uncultured microbes, which are also known as “microbial dark matter,” may play crucial roles in maintaining the ecosystem and are linked to ...

Seasonal Variations in the Foraging Strategies of Plateau Pikas (<i>Ochotona curzoniae</i>). [PDF]

Animals (Basel)
This study investigates the foraging habits and dietary niche characteristics of plateau pikas (Ochotona curzoniae) by analyzing differences between the cold and warm seasons using stable isotope analysis of carbon and nitrogen in liver, muscle, and fur organs. The results indicated that in the cold season, the plant species incorporated into different

Can pikas hold the umbrella? Understanding the current and future umbrella potential of keystone species Pika (Ochotona spp.)

Global Ecology and Conservation, 2022
The umbrella species concept is a frequently used concept in conservation since the conservation of an umbrella species may benefit other species. Keystone species are often suggested as potential umbrella species, but the validity of this approach ...

Transcriptome analysis of pika heart tissue reveals mechanisms underlying the adaptation of a keystone species on the roof of the world

Frontiers in Genetics, 2022
High-altitude environments impose intense stresses on living organisms and drive striking phenotypic and genetic adaptations, such as hypoxia resistance, cold tolerance, and increases in metabolic capacity and body mass. As one of the most successful and

Enzymatic Kinetic Properties of the Lactate Dehydrogenase Isoenzyme C₄ of the Plateau Pika (Ochotona curzoniae). [PDF]

Int J Mol Sci, 2016
Testis-specific lactate dehydrogenase (LDH-C4) is one of the lactate dehydrogenase (LDH) isozymes that catalyze the terminal reaction of pyruvate to lactate in the glycolytic pathway. LDH-C4 in mammals was previously thought to be expressed only in spermatozoa and testis and not in other tissues.

Neisseria chenwenguii sp. nov. isolated from the rectal contents of a plateau pika (Ochotona curzoniae). [PDF]

Antonie Van Leeuwenhoek, 2019
Two Gram-stain negative, catalase positive, coccus shaped bacteria, designated 10023T and 10010, were isolated from the rectal contents of a plateau pika (Ochotona curzoniae) in Qinghai-Tibet Plateau, China. Based on 16S rRNA gene sequence analysis, phylogenetic trees showed that these two isolates (10023T, 10010) group with members of the genus ...

Group-living decrease predation risk of individual: Evidence from behavior, hormones and reproduction of plateau pika

Frontiers in Ecology and Evolution, 2023
Extensive research confirms that abiotic stressors like predation risk can profoundly affect animal condition. However, there is a lack of experimental research assessing the suite of physiological responses to risk.
