TL;DR: This study provides the first evidence on the occurrence of several pharmaceuticals in marine environment including amoxicillin, lidocaine, citalopram or tramadol, among others, as well as suggesting that currents play an important role in the dilution of the target compounds.

Impact of suboxia on sinking particulate organic carbon: Enhanced carbon flux and preferential degradation of amino acids via denitrification
TL;DR: In this paper, the authors examined the attenuation of particulate organic carbon (POC) through the oxygen deficient waters in the eastern tropical North Pacific and found that degradation proceeded at similar rates under oxic and suboxic conditions, but a greater fraction of bulk POC was resistant to degradation in the suboxic experiments.

Benthic community metabolism in four temperate stream systems: An inter-biome comparison and evaluation of the river continuum concept

TL;DR: Benthic community metabolism was studied on four stream systems located in different biomes in the United States to test the hypothesis that a transition in community metabolism will occur from a predominance of heterotrophy in headwaters to a predominances of autotro Murphy in mid-sized reaches, with a return to heterotrophic further downstream.

Chlorophyll a fluorescence in marine centric diatoms: Responses of chloroplasts to light and nutrient stress
TL;DR: An investigation of continuous cultures of Cyclotella nana showed that in vivo chlorophyll a fluoresced more strongly in nitrogen-starved cells than in enriched ones, and photoinhibition of cellular fluorescence also increased with the cell's state of nitrogen deficiency.
Journal ArticleDOI
Grazing Effects of Four Marine Intertidal Herbivores on the Microflora
TL;DR: Differences in grazer zonation and use of macroalgae, coupled with increased food availability during reproductive seasons (winter and spring), allow continued coexistence of these very similar herbivores.
