Soil Organic Carbon Content and Density in Response to Pika Outbreaks Along the Altitudinal Gradient in Alpine Meadows of the Qinghai–Tibet Plateau, West China

open access: yesLand
This study investigated the effects of plateau pika (Ochotona curzoniae) disturbances and altitude on soil organic carbon (SOC) storage characteristics, including SOC content and SOC density (SOCD).

Re-evaluating climate as the best predictor of pika (Ochotona princeps) surface activity [PDF]

open access: yes, 2016
Alpine and subalpine ecosystems are expected to experience a disproportionate amount of warming in the coming decades. Rising temperatures in these ecosystems threatens biodiversity and water resources globally. The American pika (Ochotona princeps) is a

How do plateau pikas use burrows during population reestablishment?

open access: yesGlobal Ecology and Conservation
The construction of burrow systems is one of the most important challenges for burrowing animals, especially during population reestablishment. Efficient use of the existing resources could help improve the survival chances. To explore the strategies burrowing animals take in using the burrow resources, we conducted monthly field monitoring of the four

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

open access: yesEcosphere, 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 ...

Rangeland Degradation: Causes, Consequences, Monitoring Techniques and Remedies [PDF]

open access: yes, 2019
Rangelands occupy 25% of the total land surface globally. In Africa, rangelands are estimated to cover 66% of the land surface, although there are variations from country to country.

Identifying the Relative Contributions of Climate and Grazing to Both Direction and Magnitude of Alpine Grassland Productivity Dynamics from 1993 to 2011 on the Northern Tibetan Plateau [PDF]

open access: yes, 2017
Alpine grasslands on the Tibetan Plateau are claimed to be sensitive and vulnerable to climate change and human disturbance. The mechanism, direction and magnitude of climatic and anthropogenic influences on net primary productivity (NPP) of various ...

Genetic survey of alveolar and cystic echinococcoses in Romania: first molecular evidence of Echinococcus multilocularis in humans in the country [PDF]

open access: yes, 2017
Cystic echinococcosis (CE) and alveolar echinococcosis (AE) are considered as one of the most important zoonotic diseases in Romania, where they are subject to mandatory reporting.

The accelerating influence of humans on mammalian macroecological patterns over the late Quaternary [PDF]

open access: yes, 2019
The transition of hominins to a largely meat-based diet ~1.8 million years ago led to the exploitation of other mammals for food and resources. As hominins, particularly archaic and modern humans, became increasingly abundant and dispersed across the ...

Preference for ground cover when selecting burrow entrances in plateau pikas

open access: yesEcology and Evolution
AbstractBurrow‐dwelling animals such as the plateau pika (Ochotona curzoniae) often seek sturdy entrances for their burrows, which can reduce the need for frequent maintenance. The toughness of the ground surface is often reinforced by the interweaving of plant roots and often varies with the root characteristics.
