Integrative Zoology, Volume 17, Issue 3, Page 379-395, May 2022., 2022 The composition and functional profiles of gut microbiota in plateau pikas changed among seasons. Environmental factors (especially diet) had significant effect on it. This study provides new evidence of how external factors affect the intestinal environment of small mammals.

Life‐history traits and fitness of plateau pika (Ochotona curzoniae) in alpine meadow ecosystem
Ecology and Evolution, Volume 12, Issue 1, January 2022., 2022 Plateau pika is an endemic mammal living at the alpine meadow ecosystem in Qinghai–Tibet Plateau. We studied plateau pika life history by mark–recapturing plateau pika in the field and by tracking and recording a reproductive population in half‐captivity.

Comparative Karyology of North Palaearctic Pikas (Ochotona, Ochotonidae, Lagomorpha) [PDF]
Caryologia, 1973 SUMMARYThe chromosomes of the following pikas (Ochotona) are described: O. pusilla, 2n = 68; O. rutila and O. macrotis, 2n = 62; O. rufescens, 2n = 60; O. daurica, 2n = 50; O. alpina, 2n=42; O. hyperborea, 2n = 40; O. pricei, 2n = 38. O. alpina and O. hyperborea are proved to be independent species.It is shown that O.

Gene expression is implicated in the ability of pikas to occupy Himalayan elevational gradient.
PLoS ONE, 2018 Species are shifting their ranges due to climate change, many moving to cooler and higher locations. However, with elevation increase comes oxygen decline, potentially limiting a species' ability to track its environment depending on what mechanisms it ...

The Anatomical Record, EarlyView.Analysis of cranial endocast data of 181 extant and 41 fossil species from Euarchontoglires shows that there was a reduction in olfactory bulb size in Crown Primates, but that there were also subsequent reductions in various other primate clades (Anthropoidea, Catarrhini, Platyrrhini, crown Cercopithecoidea, Hominoidea).

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 ...

Revision of the subspecies of the American pika, Ochotona princeps (Lagomorpha: Ochotonidae) [PDF]
Journal of Mammalogy, 2010 Abstract Historically, a large number of taxonomic forms has been recognized within Nearctic pikas (Lagomorpha: Ochotonidae; Ochotona), including up to 13 species and 37 subspecies. After 1965, 2 species and 37 forms have been recognized: the monotypic O. collaris of Alaska, British Columbia, Yukon, and Northwest Territories, and O.
