Nucleosynthesis in ONeMg Novae: Models versus Observations to Constrain the Masses of ONeMg White Dwarfs and Their Envelopes [PDF]

, 1999
Nucleosynthesis in ONeMg novae has been investigated with the wide ranges of three parameters, i.e., the white dwarf mass, the envelope mass at ignition, and the initial composition.

Combined stable isotope and gut contents analysis of food webs in plant-dominated, shallow lakes [PDF]

, 2003
1. To determine feeding links between primary producers, invertebrates and fish, stable isotope analyses and gut content analyses of fish were conducted on the components of four shallow, eutrophic to hypertrophic, plant-dominated lakes. 2.

Phosphorus Dynamics and Availability in the Nearshore of Eastern Lake Erie: Insights From Oxygen Isotope Ratios of Phosphate

Frontiers in Marine Science, 2018
Blooms of filamentous benthic algae that plagued Lake Erie in the 1950s through 1970s were largely reduced through reductions of phosphorus (P) loading from point sources.

Do trophic subsidies affect the outcome of introductions of a non-native freshwater fish? [PDF]

, 2013
Understanding how environmental variables and human disturbances influence the outcomes of introductions of non-native freshwater fish is integral to their risk management. This can be complex in freshwater ecosystems that receive subsidies that increase

Effect of groundwater on the ecological water environment of typical inland lakes in the Inner Mongolian Plateau

Journal of Groundwater Science and Engineering, 2022
To explore the causes of the ecological environment deterioration of lakes in the Inner Mongolia Plateau, this study took a typical inland lake Daihai as an example, and investigated the groundwater recharge in the process of lake shrinkage and ...

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

Non-ideality of quantum operations with the electron spin of a 31P donor in a Si crystal due to interaction with a nuclear spin system [PDF]

, 2003
We examine a 31P donor electron spin in a Si crystal to be used for the purposes of quantum computation. The interaction with an uncontrolled system of 29Si nuclear spins influences the electron spin dynamics appreciably.

Phosphorus in the coarse soil fraction is related to soil organic phosphorus mineralization measured by isotopic dilution [PDF]

Soil Biology and Biochemistry, 2016
A sound prediction of soil organic phosphorus (Po) mineralization would be helpful to improve fertilizer recommendations. However, in most mineral soils expensive and time consuming isotopic dilution experiments are required to assess Po mineralization.

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 ...
