Calcareous benthic foraminifera from the upper central peruvian margin: Control of the assemblage by pore water redox and sedimentary organic matter
(Inter Research, 2015)
We studied 'living' (stained) benthic foraminifera in the upper border of the Peruvian oxygen minimum zone (OMZ) to determine the relationship between species' distribution and pore water and sediment geochemistry under ...
Interaction effects on galaxy pairs with Gemini/GMOS - II: oxygen abundance gradients
(Wiley, 2014-09)
In this paper, we derive oxygen abundance gradients from HII regions located in 11 galaxies in eight systems of close pairs. Long-slit spectra in the range 4400?7300 Å were obtained with the Gemini Multi-Object Spectrograph ...
Physical-chemical factors influencing the vertical distribution of phototrophic pico-nanoplankton in the Oxygen Minimum Zone (OMZ) off Northern Chile: The relative influence of low pH/low O2 conditions
(2022)
The vertical distribution of phytoplankton is of fundamental importance in the structure, dynamic, and biogeochemical pathways in marine ecosystems. Nevertheless, what are the main factors determining this distribution ...
Multidecadal changes in marine subsurface oxygenation off central Peru during the last ca. 170 years
(Frontiers Media, 2019)
Subsurface water masses with permanent oxygen deficiency (oxygen minimum zones, OMZ) are typically associated with upwelling regions and exhibit a high sensitivity to climate variability. Over the last decade, several ...
Diversity patterns along and across the chilean margin:a continental slope encompassing oxygen gradients and methane seep benthic habitats
(WILEY-BLACKWELL PUBLISHING, INC, 2010)
In the present study we review datasets available for the Chilean margin to assess the relationship between environmental (or habitat) heterogeneity and benthic diversity. Several factors, such as the presence of different ...
Macrobenthic communities in a shallow normoxia to hypoxia gradient in the Humboldt upwelling ecosystem
(2018)
Hypoxia is one of the most important stressors affecting the health conditions of coastal eco-systems. In highly productive ecosystems such as the Humboldt Current ecosystem, the oxygen minimum zone is an important abiotic ...
