Abstract:
... Inland saline waters in Central Asia constitute an important part of steppe ecosystems, providing considerable ecological functions and ecosystem services. Here we aim to present a multi-spatial scale analysis of nutrient cycling and transport waterbird guilds, and the environmental attributes of saline-soda aquatic ecosystems in Kazakhstan. The density, biomass, and diversity of waterbird guilds ...

Abstract:
... From micro to planetary scales, spatial heterogeneity—patchiness—is ubiquitous in ecosystems, defining the environments in which organisms move and interact. However, most large‐scale models still use spatially averaged ‘mean fields’ to represent natural populations, while fine‐scale spatially explicit models are mostly restricted to particular organisms or systems. In a conceptual paper, Grünbaum ...

Abstract:
... The Avars settled the Carpathian Basin in 567/68 CE, establishing an empire lasting over 200 years. Who they were and where they came from is highly debated. Contemporaries have disagreed about whether they were, as they claimed, the direct successors of the Mongolian Steppe Rouran empire that was destroyed by the Turks in ∼550 CE. Here, we analyze new genome-wide data from 66 pre-Avar and Avar-pe ...

Abstract:
... Addressing serious grassland degradation without exacerbating already low herder incomes is a major challenge for the Chinese government. In response, the Grassland Ecosystem Subsidy and Award Scheme (GESAS) was introduced in 2011 where herders receive payments if they comply with specified stocking rates set at more sustainable levels. However, compliance with GESAS, as well as low herder incomes ...

It remains unclear how soil microbes respond to labile organic carbon (LOC) inputs and how temperature sensitivity (Q₁₀) of soil organic matter (SOM) decomposition is affected by LOC inputs in a short-term. In this study, ¹³C-labeled glucose was added to a pristine grassland soil at four temperatures (10, 15, 20, and 25 °C), and the immediate utilization of LOC and native SOM by microbes was measu ...
