Lowland tundra plant stoichiometry is somewhat resilient decades following fire despite substantial and sustained shifts in community structure

Arctic, Antarctic, and Alpine Research, 2022
The Arctic is experiencing the greatest increase in average surface temperature globally, which is projected to amplify wildfire frequency and severity. Wildfire alters the biogeochemical characteristics of arctic ecosystems. However, the extent of these

Decay processes in Salix psammophila sand barriers increase soil microbial element stoichiomery ratios

Frontiers in Environmental Science, 2022
Salix psammophila sand barriers are a widely used engineering measure to control quicksand in northwest China. Thus, it is important to elucidate the influence of the sand barrier decay process on soil microbial ecological stoichiometric characteristics ...

Astrobiological Stoichiometry [PDF]

Astrobiology, 2014
Chemical composition affects virtually all aspects of astrobiology, from stellar astrophysics to molecular biology. We present a synopsis of the research results presented at the "Stellar Stoichiometry" Workshop Without Walls hosted at Arizona State University April 11-12, 2013, under the auspices of the NASA Astrobiology Institute.

Divergent adaptations of leaf functional traits to light intensity across common urban plant species in Lanzhou, northwestern China

Frontiers in Plant Science, 2023
Leaves are the most important photosynthetic organs in plants. Understanding the growth strategy of leaves in different habitats is crucial for elucidating the mechanisms underlying plant response and adaptation to the environment change.

Stoichiometric homeostasis of N:P ratio drives species-specific symbiotic N fixation inhibition under N addition

Frontiers in Plant Science, 2023
IntroductionSymbiotic N fixation inhibition induced by N supply to legumes is potentially regulated by the relative N and P availability in soil. However, the specific responses of different legume species to changes in N:P availability remain unclear ...

NPK Fertilization of Serianthes Plants Influences Growth and Stoichiometry of Leaf Nutrients

Horticulturae, 2022
The genus Serianthes has not received adequate research attention, leaving large gaps in the knowledge required to inform conservation decisions. For example, nutrient management protocols are not understood due to lack of research.

Topological Features of the Alluaudite-Type Framework and Its Derivatives: Synthesis and Crystal Structure of NaMnNi₂(H_2/3PO₄)₃

Crystals, 2021
A new sodium manganese-nickel phosphate of alluaudite supergroup with the general formula NaMnNi2(H2/3PO4)3 was synthesized by a hydrothermal method. The synthesis was carried out in the temperature range from 540 to 660 K and at the general pressure of ...

Forefront of Na+/Ca2+ Exchanger Studies: Stoichiometry of Cardiac Na+/Ca2+ Exchanger; 3:1 or 4:1?

Journal of Pharmacological Sciences, 2004
The stoichiometry of the Na+/Ca2+ exchanger (NCX) had been generally accepted as 3Na+:1 Ca2+. However, recently a challenging stoichiometry of 4:1 was proposed.
