Nutrient distributions over the Southwestern South Atlantic continental shelf from Mar del Plata (Argentina) to Itajai (Brazil): Winter-summer aspects
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Nutrient distributions observed at some depths along the continental shelf from 27 degrees 05`S (Brazil) to 39 degrees 31`S (Argentina) in winter, 2003 and summer, 2004 related to salinity and dissolved oxygen (mL L-1) and ...
Sedimentation rates of nutrients and particulate material in pond mariculture of shrimp (Litopenaeus vannamei) carried out with different management strategies
(2021-03-15)
Marine shrimp farming is an important economic activity in tropical and subtropical regions, but its expansion has contributed to the increase of nutrients and organic matter in coastal ecosystems. Thus, this work evaluated ...
Excessive nutrient input induces an ecological cost for aphids by modifying their attractiveness towards mutualist ants
1. Enhanced soil nutrient availability often favors herbivore performance by bringing the carbon:nutrient ratio of plants closer to herbivore requirements. However, a surplus of nutrients can promote a too low carbon:nutrient ...
Differential impacts of global change variables on coastal South Atlantic phytoplankton: Role of seasonal variations
(Elsevier, 2017-01-24)
Global change is associated to the increase in temperature (T), nutrient inputs (Nut) and solar radiation in the water column. To address their joint impact on the net community production [NCP], respiration [CR] and PSII ...
Extreme and gradual rainfall effects on winter and summer estuarine phytoplankton communities from Patagonia (Argentina)
(Elsevier, 2021-01)
Rainfall events bring both, terrigenous materials (including DOM) and nutrients to the aquatic system (e.g., via riverine runoff) having potential effects on the structure and metabolism of the phytoplankton communities. ...
Nitrogen availability facilitates phosphorus acquisition by bloom-forming cyanobacteria
(Oxford University Press, 2019)
Cyanobacterial blooms are threatening freshwater ecosystems. The physiological basis involved in the onset of cyanobacterial bloom is fundamental to advance in bloom predictions. Generally, cyanobacteria grow until the ...
