The responses of different insect guilds to grassland degradation in northeastern China

Ecological Indicators, 2021
Grassland insect diversity in many parts of the world is severely threatened by recent deterioration caused by global change and human activities. Insect species richness and abundance are likely sensitive to grassland degradation because of changes in ...

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

The Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Stages of grassland degradation in subalpine ecosystems of the Central Caucasus, Russia

Chilean Journal of Agricultural Research, 2021
Overgrazing and grassland degradation are significant environmental problems in the mountain ecosystems of the Central Caucasus. The aim was to define the criteria for the stages of grassland degradation to provide land managers with useful guidelines on

Beyond grassland degradation: Pathways to resilience for pastoralist households in alpine grassland ecosystems

Journal of Environmental Management
Sustaining the development of rural and pastoral communities' hinges on livelihood resilience. Pastoralist household resilience relies on resource availability and decision-making abilities. Despite extensive studies on pastoralist livelihoods, a significant knowledge gap remains in understanding the nuanced adaptive capacities of diverse households ...

Grassland Degradation Decrease the Diversity of Arbuscular Mycorrhizal Fungi Species in Tibet Plateau

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2014
Arbuscular mycorrhizal (AM) fungi play a vital role in restoration of an ecosystem. Grassland degradation in alpine steppe is severe, but the influence of grassland degradation on AM fungi composition in Tibetan Plateau is still not well understood. This

Predicting parameters of degradation succession processes of Tibetan Kobresia grasslands [PDF]

Solid Earth, 2015
Abstract. In the past two decades, increasing human activity (i.e., overgrazing) in the Tibetan Plateau has strongly influenced plant succession processes, resulting in the degradation of alpine grasslands. Therefore, it is necessary to diagnose the degree of degradation to enable implementation of appropriate management for sustainable exploitation ...

Subterranean environments contribute to three‐quarters of classified ecosystem services

Biological Reviews, EarlyView.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Epigeic arthropod community changes in response to livestock-caused alpine grassland degradation on the eastern Qinghai-Tibetan Plateau

Global Ecology and Conservation, 2022
As one of the most important ecosystems, grassland ecosystems maintain an abundance of flora and fauna, and provide humans with rich resources. The structure and function of most grassland ecosystems around the world have been significantly affected by ...
