Invertebrate herbivory accelerates shift towards forbs caused by warming in a sedge‐dominated alpine meadow

چکیده

Invertebrate herbivory is suggested to modulate community shifts caused by climate warming in grasslands. However, experimental evidence lacking, especially high elevation areas. We examined the interactive effect of and grassland caterpillar Gynaephora alpherakjj, a typical invertebrate herbivorous insect with sedge preference, on structure plant sedge-dominated alpine meadow Tibetan Plateau. manipulated both herbivore temperature full factorial field experiment using passive chambers over one plant-growing season. Results show that simulated significantly increased aboveground biomass (APB) forbs total APB, while presence caterpillars decreased APB APB. The increase consumption sedges under warmed conditions can largely be ascribed feeding time caterpillars. Importantly, ratio but not unwarmed chambers. These results suggest climate, could accelerate from dominance forb only season meadow. This shift would reduce high-quality forage further threaten animal husbandry this area. Considering harm G. alpherakjj grasslands, its population should controlled more strictly global scenario.

Experimental warming increases herbivory by leaf‐chewing insects in an alpine plant community

Climate warming is predicted to affect species and trophic interactions worldwide, and alpine ecosystems are expected to be especially sensitive to changes. In this study, we used two ongoing climate warming (open-top chambers) experiments at Finse, southern Norway, to examine whether warming had an effect on herbivory by leaf-chewing insects in an alpine Dryas heath community. We recorded feed...

Soil bacterial community responses to warming and grazing in a Tibetan alpine meadow.

Warming and grazing significantly affect the structure and function of an alpine meadow ecosystem. Yet, the responses of soil microbes to these disturbances are not well understood. Controlled asymmetrical warming (+1.2/1.7°C during daytime/nighttime) with grazing experiments were conducted to study microbial response to warming, grazing and their interactions. Significant interactive effects o...

Insects Overshoot the Expected Upslope Shift Caused by Climate Warming

Along elevational gradients, climate warming may lead to an upslope shift of the lower and upper range margin of organisms. A recent meta-analysis concluded that these shifts are species specific and considerably differ among taxonomic lineages. We used the opportunity to compare upper range margins of five lineages (plants, beetles, flies, hymenoptera, and birds) between 1902-1904 and 2006-200...

Experimental warming induces degradation of a Tibetan alpine meadow through trophic interactions

1. It is well known that climate change alters abiotic factors (temperature and water availability) that directly affect ecosystem properties. However, less is known about the indirect impacts of climate change on ecosystem structure and function. Here, we show that experimental warming may deteriorate ecosystems via trophic interactions. 2. In a Tibetan alpine meadow, plant species composition...

Warming decreased and grazing increased plant uptake of amino acids in an alpine meadow

Organic nitrogen (N) uptake by plants has been recognized as a significant component of terrestrial N cycle. Several studies indicated that plants have the ability to switch their preference between inorganic and organic forms of N in diverse environments; however, research on plant community response in organic nitrogen uptake to warming and grazing is scarce. Here, we demonstrated that organi...
