Functional evolution of leptin of Ochotona curzoniae in adaptive thermogenesis driven by cold environmental stress.

PLoS ONE, 2011
BackgroundEnvironmental stress can accelerate the directional selection and evolutionary rate of specific stress-response proteins to bring about new or altered functions, enhancing an organism's fitness to challenging environments.

Moderate plateau pika activity had minor effect on ecosystem C and N in alpine grasslands

Global Ecology and Conservation
Plateau pika (Ochotona curzoniae, hereafter pika) is an ecosystem engineer on the Qinghai-Tibetan Plateau (QTP), whose activity exerts a profound effect on the ecosystem nutrient cycle of alpine grasslands.

Species Monitoring Using Unmanned Aerial Vehicle to Reveal the Ecological Role of Plateau Pika in Maintaining Vegetation Diversity on the Northeastern Qinghai-Tibetan Plateau

Remote Sensing, 2020
Plateau pika (Ochotona curzoniae, hereafter pika) is considered to exert a profound impact on vegetation species diversity of alpine grasslands. Great efforts have been made at mound or quadrat scales; nevertheless, there is still controversy about the ...

Experimental Stomach-ulcer on Pika

Experimental Animals, 1990
Experimental gastric ulcer formation was performed in the pika and compared with that in the rat. Gastric ulcers were formed in pika that were subjected to water restraint for 4-5 days for 2 hours each day. Gastric ulcers were also formed under conditions of 1-4 days for 3 hours each day and 1-2 days for 5 hours each day.

Revisiting paravertebral muscles in European rabbits (Oryctolagus cuniculus) and European brown hares (Lepus europaeus) (Leporidae; Lagomorpha)

The Anatomical Record, EarlyView.
Abstract Domesticated European rabbits (Oryctolagus cuniculus) have long been chosen as laboratory model organisms. Despite this, there has been no definitive study of the vertebral musculature of wild rabbits. Relevant descriptions of well‐studied veterinary model mammals (such as dogs) are generally applicable, but not appropriate for a species ...

Scaling and ecomorphology of lagomorph body shape and appendicular skeleton

The Anatomical Record, EarlyView.
Abstract Body shape is one of the most prominent features of phenotypic variation. Yet, mammalian body shapes are poorly quantified and the underlying components contributing to its diversity and its relationship to other skeletal components are rarely tested.

Integrating Remote Sensing, Archaeological Survey and Geophysical Prospections for the Enhancement of Roman Doclea, Montenegro

Archaeological Prospection, EarlyView.
ABSTRACT The Roman city of Doclea is a key archaeological site of Montenegro, valued for its impressive remains and its role in the nation's cultural identity within European and the Mediterranean history. Doclea was the second‐largest city in the province of Roman Dalmatia, a municipium created in the first century ad and named after the Illyrian ...

Pika burrow and zokor mound density and their relationship with grazing management and sheep production in alpine meadow

Ecosphere, 2020
Plateau pikas (Ochotona curzoniae) and plateau zokors (Myospalax baileyi) occur naturally in the alpine meadow of the Qinghai–Tibet Plateau (QTP). Their feeding and burrowing activities affect plant composition and soil properties (e.g., soil carbon ...

Phylogeography of the Plateau Pika (Ochotona curzoniae) in Response to the Uplift of the Qinghai-Tibet Plateau

Diversity, 2023
The evolution and current distribution of species on the Qinghai-Tibet Plateau have been significantly impacted by historical occurrences, including the uplift of the plateau and the Quaternary climate upheaval.

Animal empathy reconsidered: a multidimensional profile account

Biological Reviews, EarlyView.
ABSTRACT Empathy is the glue that holds societies together and yet several fundamental questions about empathy persist. What is empathy (the definitional question)? Is it uniquely human and, if not, which nonhuman animals possess empathy (the distribution question)? Which type or quality of empathy is realized in different species (the quality question)
