Interactions between carbon and nitrogen dynamics in estimating net primary productivity for potential vegetation in North America [PDF]

open access: yes, 1992
We use the terrestrial ecosystem model (TEM), a process-based model, to investigate how interactions between carbon (C) and nitrogen (N) dynamics affect predictions of net primary productivity (NPP) for potential vegetation in North America. Data on pool

Endodermal apoplastic barriers are linked to osmotic tolerance in meso-xerophytic grass Elymus sibiricus

open access: yesFrontiers in Plant Science, 2022
Drought is the most serious adversity faced by agriculture and animal husbandry industries. One strategy that plants use to adapt to water deficits is modifying the root growth and architecture.

Effects of shrub encroachment on grassland community and soil nutrients among three typical shrubby grasslands in the alpine subhumid region of the Qinghai-Tibet Plateau, China

open access: yesFrontiers in Ecology and Evolution, 2022
IntroductionThe alpine meadows are distributed widely and play a vital role in ecosystem service functions on the Qinghai-Tibet Plateau (QTP). Under the combined effect of climate change and overgrazing, shrubs display an apparent expansion trend ...

Focus on the impact of climate change on wetland ecosystem and carbon dynamics [PDF]

open access: yes, 2016
The renewed growth in atmospheric methane (CH4)since 2007 after a decade of stabilization has drawn much attention to its causes and future trends. Wetlands are the single largest source of atmospheric CH4.

Alpine wetland degradation reduces carbon sequestration in the Zoige Plateau, China

open access: yesFrontiers in Ecology and Evolution, 2022
Alpine wetland plays an important role in the global carbon balance but are experiencing severe degradation under climate change and human activities. With the aim to clarify the effect of alpine wetland degradation on carbon fluxes (including net ecosystem CO2 exchange, NEE; ecosystem respiration, ER; gross ecosystem productivity, GEP, and CH4 flux ...

Changes Detection and Object-Oriented Classification of Major Wetland Cover Types in Response to Driving Forces in Zoige County, Eastern Qinghai–Tibetan Plateau

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The Zoige alpine wetland of eastern Qinghai–Tibetan Plateau is one of the most important wetlands in the world, which suffered stronger human regulations of decades’ drainage and recent restoration.

Tussock microhabitats increase nitrogen uptake by plants in an alpine wetland

open access: yesPlant and Soil, 2021
Tussock microhabitat is a universal phenomenon in wetlands, where soil and plant properties differ from their surrounding lawns. This study aims to investigate the differences of plant nitrogen (N) uptake between tussocks and lawns, which would further affect ecosystem functions.

A new species of Megastigmus (Hymenoptera, Megastigmidae) from China [PDF]

open access: yesBiodiversity Data Journal, 2023
Most species of Megastigmus are considered important economic pests that grow in seeds, especially of conifers. Accurate identification of species is a crucial step for the biological research of parasitic pests and the further application of biological ...

Haplotype-resolved genomes of two buckwheat crops provide insights into their contrasted rutin concentrations and reproductive systems

open access: yesBMC Biology, 2023
Background Two widely cultivated annual buckwheat crops, Fagopyrum esculentum and F. tataricum, differ from each other in both rutin concentration and reproductive system. However, the underlying genetic mechanisms remain poorly elucidated. Results Here,
