Maqui (Aristotelia chilensis [Mol.] Stuntz) morphological and phenolic traits associated with forests type and latitudinal gradient in natural populations of Patagonia Argentina
(Elsevier, 2021-12)
Maqui (Aristotelia chilensis [Mol.] Stuntz) is a native berry of the Patagonia Andean forests, which has one of the highest antioxidant levels currently known. This biochemical characteristic strongly depends on the phenolic ...
Modelling key variables for understanding the effects of grazing and nutrient recycling by zooplankton on the freshwater microbial loop
1. Pelagic microbial food webs are structured by zooplankton through grazing and nutrient recycling. Cladocerans and copepods are assumed to display different effects on the microbial loop by grazing on different prey sizes ...
Light intensity regulates stoichiometry of benthic grazers through changes in the quality of stream periphyton
(University of Chicago Press, 2019-06)
In mountain streams, light is a key factor for primary production and primary producer nutrient stoichiometry, or the relative composition of carbon (C) compared to phosphorous (P) and nitrogen (N) in primary producers. ...
