Trophic relationships of exotic anadromous salmonids in the southern Patagonian Shelf as inferred from stable isotopes
(American Society of Limnology and Oceanography, 2008-12)
On the basis of their thermal preferences, salmon introduced in South America can distribute over the whole Southern Patagonian Shelf Ecosystem (SPSE). Stable isotope (δ13C and δ15N) data show that the SPSE is dominated ...
Perceiving the algae: How feeding-current feeding copepods detect their nonmotile prey
(American Society of Limnology and Oceanography, 2015-03)
Feeding-current feeding copepods detect and capture prey individually, but the mechanism by which nonmotile prey is detected has been unclear. Early reports that copepods detect phytoplankton prey at distances of one body ...
Calculation of spectral weighting functions for the solar photobleaching of chromophoric dissolved organic matter in temperate lakes
(American Society of Limnology and Oceanography, 2001-12)
The effect of solar radiation on the dissolved absorption coefficient (aCDOM[λ]), which reflects the concentration of chromophoric dissolved organic matter (CDOM), was investigated in several lakes near Bariloche, Argentina ...
Ocean acidification exacerbates the effect of UV radiation on the calcifying phytoplankter Emiliania huxleyi
(American Society of Limnology and Oceanography, 2009-12)
Increasing atmospheric CO2 concentration affects calcification in most planktonic calcifiers. Both reduced or stimulated calcification under high CO2 have been reported in the widespread coccolithophore Emiliania huxleyi. ...
