The interactive effects of Cu and light on a coastal California picophytoplankton community were assessed during four incubation experiments using a 7x7 matrix of overlapping Cu and light gradients. Consistent with prior knowledge, sensitivity to Cu was greatest in Prochlorococcus, followed by Synechococcus, and then picoeukaryotes. In September, Prochlorococcus abundance declined with Cu additions >6 nM, whereas Synechococcus showed a toxicity threshold at >10 nM added Cu. An unexpected environmental increase in ambient seawater Cu prior to the October experiments brought Prochlorococcus and Synechococcus close to their toxicity thresholds, potentiating their sensitivity to light during October experiments. Synergistic effects between Cu and light exacerbated toxicity in both taxa, suggesting saturation of shared physiological stress response pathways. Addition of 10 mM nitrate at the start of one experiment did not rescue populations from this synergistic toxicity, eg, by allowing de novo stress response enzyme synthesis. Across all experiments, picoeukaryotes were more resilient to high light and Cu, allowing them to persist or increase under conditions that limited Prochlorococcus and Synechococcus. This robustness combined with relief from resource competition upon decline of the other two taxa, ultimately led picoeukaryotes to dominate the communities despite having very low baseline relative abundances. Selection for different Synechococcus clades and picoeukaryote species likely permitted each of these populations to thrive over a broader range of Cu and light combinations than would be possible for populations with lower diversity.', }, + { + title: + 'The dynamic mesoscale sink and source niches for eukaryotic phytoplankton in a subtropical gyre', + published_info: 'Proceedings of the National Academy of Sciences, 123, 25', + authors: + 'Jones-Kellett, AE, JC McNichol, Y Raut, JA Fuhrman, MJ Follows (2026)', + doi: 'https://doi.org/10.1073/pnas.2608700123', + abstract: + 'By tracking the water mass histories of genetic samples, we investigated the biophysical dynamics shaping eukaryotic phytoplankton populations in a nutrient-deplete subtropical gyre, where cyanobacteria have a competitive advantage. Triplicate seawater samples were filtered every 46 km along a 2,382 km North Pacific transect, spiked with genomic internal standards, and amplified with a three-domain primer set to obtain absolute 16S and 18S rRNA volumetric gene abundances. The transport histories of each sample were simulated by advecting mesoscale Lagrangian particle clouds in satellite remote sensing velocity fields. Consistent with previous field studies, eukaryotic phytoplankton were anomalously abundant within eddies and along eddy-edges, where vertical circulations redistribute nutrients. Outside of eddies, we found a statistically significant decline in eukaryotes as a function of lateral coherence: Waters that recently mixed from multiple origins supported eukaryote anomalies resembling those of eddies, whereas eukaryotic populations were depressed from isolation in waters that were coherent for three or more months. In these coherent outside-eddy water masses, we estimate taxon-dependent eukaryote population half-lives range from 8 to 17 mo. Such physical conditions are relatively rare, given that 90% of the entire gyre during the sampling campaign was composed of eddies and recently mixed waters. These results derived from empirical observations substantiate the theory that eukaryotic phytoplankton would face exclusion in the subtropics on timescales of years due to competitive pressure from cyanobacteria, yet are sustained in small numbers by regular disturbances promoting opportunistic growth and dispersal.', + }, + { + title: + 'Warming transforms the western Arctic Ocean into a hub of drifting matter', + published_info: 'Nature Communications, 17, 5317', + authors: 'Wang, K, C Liu, Q Shu, C Wekerle, C Wang, Q Wang (2026)', + doi: 'https://doi.org/10.1038/s41467-026-74439-5', + abstract: + 'The Arctic Ocean is increasingly stressed by anthropogenic pollution and rapid environmental change. River discharge plays a crucial role in this transition by delivering freshwater, nutrients, carbon, and contaminants to the ocean. Yet how river-borne materials will spread through the Arctic under future climate warming remains unclear. Here we show that climate warming accelerates and expands the dispersal of Arctic river waters and drifting materials through multi-scale changes in ocean circulation linked to sea-ice decline and reduced upper-ocean density. Stronger ocean eddy activity and altered wind-driven circulation transform the Beaufort Gyre from a predominantly regional reservoir into a pan-Arctic convergence zone that efficiently accumulates river-derived materials from Siberia. Meanwhile, intensified boundary currents and Transpolar Drift accelerate the export of Siberian discharge toward the North Atlantic. Together, these circulation changes greatly increase cross-basin connectivity, with broad implications for marine ecosystems in the northern high-latitude oceans and for Arctic coastal communities.', + }, ]
