Restoring steppe landscapes: patterns, drivers and implications in Russia’s steppes [PDF]

open access: yesLandscape Ecology, 2020
AbstractContextAgricultural land abandonment across the steppe belt of Eurasia has provided an opportunity for the restoration of steppe landscapes in recent decades. However, global food demands are about to revert this trajectory and put restored steppe landscapes at risk.ObjectivesWe analysed steppe development in southern Russia in the last 40 ...

Changes in plant species richness distribution in Tibetan alpine grasslands under different precipitation scenarios [PDF]

open access: yes, 2020
Species richness is the core of biodiversity-ecosystem functioning (BEF) research. Nevertheless, it is difficult to accurately predict changes in plant species richness under different climate scenarios, especially in alpine biomes.

Competing Vegetation Structure Indices for Estimating Spatial Constrains in Carabid Abundance Patterns in Chinese Grasslands Reveal Complex Scale and Habitat Patterns

open access: yesInsects, 2020
Carabid communities are influenced by landscape features. Chinese steppes are subject to increasing desertification processes that are changing land-cover characteristics with negative impacts on insect communities. Despite those warnings, how land-cover

The Andes mountain range uplift as a vicariant event in the Pimeliinae (Coleoptera: Tenebrionidae) in southern South America [PDF]

open access: yes, 2006
The Andes mountain range extends over 8500 km along the Pacific coast of South America. Its medium altitude is 3500 m, reaching more than 6000 m at different latitudes. The uplift of the Andes  split arid habitats creating very diverse ecosystems on both

Assessing Simulations of Imperial Dynamics and Conflict in the Ancient World [PDF]

open access: yes, 2019
The development of models to capture large-scale dynamics in human history is one of the core contributions of cliodynamics. Most often, these models are assessed by their predictive capability on some macro-scale and aggregated measure and compared to ...

Grazing effects on intraspecific trait variability vary with changing precipitation patterns in Mongolian rangelands

open access: yesEcology and Evolution, 2020
Functional traits are proxies for plant physiology and performance, which do not only differ between species but also within species. In this work, we hypothesized that (a) with increasing precipitation, the percentage of focal species which ...

Plant Community Traits Respond to Grazing Exclusion Duration in Alpine Meadow and Alpine Steppe on the Tibetan Plateau

open access: yesFrontiers in Plant Science, 2022
Grazing exclusion has been a primary ecological restoration practice since the implement of “Returning Grazing Land to Grassland” program in China. However, the debates on the effectiveness of grazing exclusion have kept for decades.
