Microbial methane production in oxygenated water column of an oligotrophic lake
TLDR
Temporal and spatial uncoupling between methanogenesis and methanotrophy was supported by field and laboratory measurements, which also helped explain the oversaturation of methane in the upper water column.

Linkage between crustacean zooplankton and aquatic bacteria
TLDR
By transcending disciplinary boundaries, microbial ecologists and zooplankton ecologists can work together to integrate the two disciplines and advance the understanding in aquatic microbial ecology.

Paradox reconsidered: Methane oversaturation in well‐oxygenated lake waters
The widely reported paradox of methane oversaturation in oxygenated water challenges the prevailing paradigm that microbial methanogenesis only occurs under anoxic conditions. Using a combination of…

Effects of protozoan grazing on colony formation in Phaeocystis globosa (Prymnesiophyceae) and the potential costs and benefits
TLDR
Colony formation by Phaeocystis globosa was enhanced in terms of colony size when solitary P. globosa cells were grazed by the heterotrophic dinoflagellates Noctiluca scintillans and Gyrodinium dominans and the costs of colony formation must be sought elsewhere.

TLDR
Experiments showed that physical contact with grazers was not required to initiate the defensive response; instead, P. globosa colony size increase was found to be stimulated by dissolved chemicals generated by ambient grazing activities.

Role of diatoms in copepod production: good, harmless or toxic?
TLDR
The evidence for the toxicity hypothesis is examined, it is argued that it has not been rigorously tested in an ecologically meaningful way, and a possible avenue to follow is proposed.

Trophic modification of essential fatty acids by heterotrophic protists and its effects on the fatty acid composition of the copepod Acartia tonsa
TLDR
Results suggest that O. marina was able to trophically upgrade the nutritional quality of the poor-quality alga, and efficiently supplied DHA to the next trophic level, suggesting that protists have the ability to elongate and desaturate 18:3, a precursor of LCn−3PUFAs, to EPA and/or DHA.

Simple staining method for differentiating live and dead marine zooplankton in field samples
TLDR
The method produced accurate results under conditions tested, and artifact mortality was negligible using the recommended protocol, which will allow for more systematic study of in situ zooplankton mortality and related processes.
