Giant phytoplankton revealed by in situ imaging
Abstract Deployment of an autonomous Zooglider in the western Mediterranean Sea revealed the presence of long phytoplankton chains attaining maximum lengths of 6.4–10.4 mm suspended in situ. Elongate chains included the diatoms Guinardia, Proboscia, two other diatom morphologies, and solitary filaments of the cyanobacterium Trichodesmium. Most elongate

Abstract The biotic component of the marine silica cycle strongly influences global biogeochemical cycling. Active uptake of dissolved silicic acid (dSi) occurs via silicon transporters (SITs), first characterized in diatoms but widely distributed in eukaryotes. Studying SITs and SIT‐like (SIT‐L) gene transcripts provides insights into the dynamics and

Grazing rates of Ochromonas CCMP2951 expressed as carbon obtained per mean cell volume (a) and Caut/het‐photosynthetically fixed carbon divided by carbon obtained through grazing (b) in the four experimental treatments. Summary Mixotrophic protists capable of both photosynthesis and phagotrophy are key members of marine plankton communities.

Fitoplancton de una laguna pampásica (San Miguel del Monte, Buenos Aires, Argentina)
Phytoplankton assemblages were analyzed taking into account the functional groups in a shallow lake connected to the lower basin of Salado River. Samples were obtained monthly (9/1997-8/1998), from the affluent (E1), San Miguel del Monte lake (E2) and ...

Abstract Frontal zones are often areas of increased biological productivity and have hydrographic gradients on short spatial scales. The small scale of gradients poses a challenge in identifying differences in zooplankton community structure and trophic transfer efficiency through the pelagic food web.

Abstract Estuarine zooplankton are vital primary consumers and essential for estuarine ecosystem functioning and productivity, but they face strong physico‐biochemical gradients and often anthropogenically altered habitats that impact their succession.

Multitrophic alpha and beta diversity of lake plankton across Canada
Anthropogenic environmental changes impact freshwater biodiversity globally. While biodiversity assessments in freshwater environments have traditionally focused on individual groups of organisms or trophic levels, considering patterns of ‘multitrophic biodiversity' across the food web provides a more comprehensive view of anthropogenic impacts and ...
