Spatiotemporal Coupling Relationship Between Plateau Pika Disturbance and Alpine Meadow Degradation

Shuitu baochi tongbao, 2023
[Objective] Plateau pika (Ochotona curzoniae) is a key species in the alpine meadow ecosystem of the Qinghai-Xizang Plateau. The coupling relationship between pika activity and meadow degradation was analyzed in order to further improve the observation ...

Effects of alpine meadow degradation on soil nematode diversity and community composition on the Qinghai-Tibet Plateau

Ecological Indicators
Soil nematodes play a critical role in maintaining ecosystem services; however, their community dynamics in response to alpine meadow degradation remain poorly understood.

High Below-Ground Productivity Allocation of Alpine Grasslands on the Northern Tibet

Plants, 2019
The allocation of net primary production (NPP) between above- and belowground components is a key step of ecosystem material cycling and energy flows, which determines many critical parameters, e.g., the fraction of below ground NPP (BNPP) to NPP (fBNPP)

Variations and Mutual Relations of Vegetation–Soil–Microbes of Alpine Meadow in the Qinghai-Tibet Plateau under Degradation and Cultivation

Land, 2022
Artificial cultivation had been applied to recover the meadow suffering from serious degradation in the Qinghai–Tibet Plateau. Studies focusing only on the changes in vegetation, soil and microbes along the meadow degradation were insufficient, and ...

No Consistent Evidence for Advancing or Delaying Trends in Spring Phenology on the Tibetan Plateau [PDF]

, 2017
Vegetation phenology is a sensitive indicator of climate change and has significant effects on the exchange of carbon, water, and energy between the terrestrial biosphere and the atmosphere.

Nitrogen economy of alpine plants on the north Tibetan Plateau: Nitrogen conservation by resorption rather than open sources through biological symbiotic fixation

Ecology and Evolution, 2020
Nitrogen (N) is one of the most important factors limiting plant productivity, and N fixation by legume species is an important source of N input into ecosystems.

Why do snails have hairs? A Bayesian inference of character evolution [PDF]

, 2005
Background: Costly structures need to represent an adaptive advantage in order to be maintained over evolutionary times. Contrary to many other conspicuous shell ornamentations of gastropods, the haired shells of several Stylommatophoran land snails ...

Influence of alpine meadow deterioration on soil microbial communities in the Yangtze River source region

Frontiers in Environmental Science, 2023
Introduction: Although soil microbial populations are a good predictor of soil texture, little is known about how they react to alpine meadow deterioration.Methods: This study utilized Illumina HiSeq sequencing to investigate the effects of alpine meadow

The genus Hebeloma in the alpine belt of the Carpathians including two new species [PDF]

, 2015
Between 2002 and 2012 regular visits to the Carpathians were made and a number of Hebeloma spp. were collected from the alpine area. In total 44 collections were made that represent 11 species, two of which, Hebeloma grandisporum and H oreophilum, are ...
