Karenia brevis blooms impair human health, marine ecosystems, and coastal economies in the Gulf of Mexico via their production of carbon-based neurotoxins (brevetoxins), which contain no nitrogen (N)...
Recently, how to quantitatively estimate the growth rate of continental crust is an enigmatic issue. With the development of ICP-MS technology, the U–Pb dating and Lu–Hf isotopic compositions of detr...
Oxygen isotope values of low-growth coral (<5 mm/yr) skeletons may reflect kinetic effects, which is problematic for sea surface temperature (SST) reconstruction. Here, we report a Sr/Ca-based SST re...
We constrain the evolution of Newton's constant using the growth rate of large-scale structure measured by the WiggleZ Dark Energy Survey in the redshift range $0.1 < z < 0.9$. We use this data in two...
The present work investigates environmental effects on the growth of fungal colonies of P. vitreus by using a lattice-free discrete modelling approach called FGM (Fuhr & Schubert,2010, arXiv:1101.1747...
We have investigated the effect of melatonin (MLT) on specific growth rate (SGR% day−1), condition factor (k), gonado-somatic-index (GSI), histological structures of gonads, serum as well as gon...
Comment: Unimodal relationship between phytoplankton-mass–specific growth rate and size: A reply to the comment by Sal and Lo′ pez-Urrutia (2011)。
We will show that the cotangent bundle of an integrally hyperbolic manifold is not symplectomorphic to any smooth affine variety. We will also show that the unit cotangent bundle of such a manifold is...
Thick, high quality 4H-SiC epilayers have been grown in a vertical hot-wall chemical vapor deposition system at a high growth rate on (0001) 80 off-axis substrates. We discuss the use of dichlorosil...
Ice crystals were grown in the laboratory at −15°C, at different growth rates and in the presence of a partial pressure of HCl of 1.63×10-3 Pa, to test whether the ice growth rate influences the...
A kinematic wave breaking criterion is applied in the calculation of the short-wave dissipation. It is found that this short-wave dissipation, due to wave-drift interactions, has the effect of suppres...
We quantify the relative roles of natural and anthropogenic influences on the growth rate of atmospheric CO2 and the CO2 airborne fraction, considering both interdecadal trends and interannual variabi...
Organic matter represents an important fraction of the fine particle aerosol, yet our knowledge of the roles of organics in the activation of aerosol particles into cloud droplets is poor.
Ecological stoichiometry is emerging as a central organizing framework upon which our perceptions of aquatic trophic dynamics are being reshaped. The microbial component of aquatic systems is crucial ...
