A New foodweb based on microbes in calcitic caves: The Cansiliella (Beetles) case in Northern Italy [PDF]

International Journal of Speleology, 2011
The troglobitic beetle, Cansiliella servadeii (Leptodirini), has specialized mouthparts modified for browsing and feeding under percolating water on moonmilk, a speleothem formation in Grotta della Foos, Italy. Results from analyses of stable isotopes of

Ecosystem engineers in the extreme: The modest impact of marmots on vegetation cover and plant nitrogen and phosphorus content in a cold, extremely arid mountain environment

Ecology and Evolution, 2023
Burrowing mammals strongly impact plant communities. One of the main effects is accelerating nutrient cycling and thus promoting plant growth. This mechanism is well‐studied in grasslands and alpine habitats, but less is known about this phenomenon in ...

ISOTOPICALLY EXCHANGEABLE PHOSPHORUS IN SOILS

Journal of Soil Science, 1958
Summary Phosphate residues in the soil were subdivided into three fractions on the basis of isotopic exchange of orthophosphate ions between the soil and the soil solution. It was observed that the total labile phosphorus was a smaller fraction of the total phosphorus in the heavier soils ( c

Mycorrhiza governs plant-plant interactions through preferential allocation of shared nutritional resources: A triple (13C, 15N and 33P) labeling study

Frontiers in Plant Science, 2022
Plant-plant interactions and coexistence can be directly mediated by symbiotic arbuscular mycorrhizal (AM) fungi through asymmetric resource exchange between the plant and fungal partners.

ISOTOPICALLY EXCHANGEABLE PHOSPHORUS IN SOILS

Journal of Soil Science, 1957
Summary Methods used to determine isotopically exchangeabIe phosphorus in soils are described and briefly analysed. The influence of soil: solution ratio, orthophosphate ions added with radio‐phosphorus, the equilibrium pH, and the removal of increasing amounts of phosphate from the soil are investigated. A scheme

Quantitative Resolution of Phosphorus Sources in an Agricultural Watershed of Southern China: Application of Phosphate Oxygen Isotopes and Multiple Models

Agronomy
Phosphorus is the primary contributor to eutrophication in water bodies, and identifying phosphorus sources in rivers is crucial for controlling phosphorus pollution and subsequent eutrophication.

Estimating submarine groundwater discharge and associated nutrient inputs into Daya Bay during spring using radium isotopes

Water Science and Engineering, 2018
Daya Bay, a semi-enclosed bay in the South China Sea, is well known for its aquaculture, agriculture, and tourism. In recent years, many environmental problems have emerged, such as the frequent (almost yearly) occurrence of harmful algal blooms and red ...
