Contrasting microbial biogeographical patterns between anthropogenic subalpine grasslands and natural alpine grasslands

Contrasting microbial biogeographical patterns between anthropogenic subalpine grasslands and natural alpine grasslands.

The effect of plant species composition on soil microbial communities was studied at the multiregional level. We compared the soil microbial communities of alpine natural grasslands dominated by Carex curvula and anthropogenic subalpine pastures dominated by Nardus stricta. We conducted paired sampling across the Carpathians and the Alps and used Illumina sequencing to reveal the molecular dive...

6170 Alpine and subalpine calcareous grasslands

Madagascar's grasses and grasslands: anthropogenic or natural?

Grasses, by their high productivity even under very low pCO2, their ability to survive repeated burning and to tolerate long dry seasons, have transformed the terrestrial biomes in the Neogene and Quaternary. The expansion of grasslands at the cost of biodiverse forest biomes in Madagascar is often postulated as a consequence of the Holocene settlement of the island by humans. However, we show ...

Overview: Anthropogenic Changes of Canadian Grasslands

Canada’s grasslands are located primarily in western Canada within the prairie provinces, but also with significant portions in the interior of British Columbia. Before European contact, their character and distribution were significantly influenced by disturbances from fire and large herbivores, which killed woody plants and produced a more arid environment where grasses were competitive. Abor...

Climate and ecosystem N natural abundance along a transect of Inner Mongolian grasslands: Contrasting regional patterns and global patterns

[1] Nitrogen isotopes provide integrated information about nitrogen cycling in terrestrial ecosystems. This study explores the regional patterns of ecosystem N abundance along a 1200 km transect in Inner Mongolian grasslands and their relationships with climate. Results indicate that climatic variables control approximately 50% of the variation in ecosystem N abundance along the transect. Ecosy...
