Multiyear analysis uncovers coordinated seasonality in stocks and composition of the planktonic food web in the Baltic Sea proper

Autor: Emil Fridolfsson, Carina Bunse, Elin Lindehoff, Hanna Farnelid, Benjamin Pontiller, Kristofer Bergström, Jarone Pinhassi, Catherine Legrand, Samuel Hylander

Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-16 (2023)

Abstract The planktonic realm from bacteria to zooplankton provides the baseline for pelagic aquatic food webs. However, multiple trophic levels are seldomly included in time series studies, hampering a holistic understanding of the influence of seas

Coastal upwelling systems as dynamic mosaics of bacterioplankton functional specialization

Autor: Erick Delgadillo-Nuño, Eva Teira, Benjamin Pontiller, Daniel Lundin, Vanessa Joglar, Carlos Pedrós-Alió, Emilio Fernández, Jarone Pinhassi, Sandra Martínez-García

Publikováno v: Frontiers in Marine Science, Vol 10 (2024)

Coastal upwelling areas are extraordinarily productive environments where prokaryotic communities, the principal remineralizers of dissolved organic matter (DOM), rapidly respond to phytoplankton bloom and decay dynamics. Nevertheless, the extent of

Seasonal Dynamics in Carbon Cycling of Marine Bacterioplankton Are Lifestyle Dependent

Autor: Sandra Martínez-García, Carina Bunse, Benjamin Pontiller, Federico Baltar, Stina Israelsson, Emil Fridolfsson, Markus V. Lindh, Daniel Lundin, Catherine Legrand, Jarone Pinhassi

Publikováno v: Frontiers in Microbiology, Vol 13 (2022)

Although free-living (FL) and particle-attached (PA) bacteria are recognized as ecologically distinct compartments of marine microbial food-webs, few, if any, studies have determined their dynamics in abundance, function (production, respiration and

Seasonal and Spatial Variations in Synechococcus Abundance and Diversity Throughout the Gullmar Fjord, Swedish Skagerrak

Autor: Christien P. Laber, Benjamin Pontiller, Carina Bunse, Christofer M. G. Osbeck, Clara Pérez-Martínez, Danilo Di Leo, Daniel Lundin, Catherine Legrand, Jarone Pinhassi, Hanna Farnelid

Publikováno v: Frontiers in Microbiology, Vol 13 (2022)

The picophytoplankton Synechococcus is a globally abundant autotroph that contributes significantly to primary production in the oceans and coastal areas. These cyanobacteria constitute a diverse genus of organisms that have developed independent nic

Taxon-Specific Shifts in Bacterial and Archaeal Transcription of Dissolved Organic Matter Cycling Genes in a Stratified Fjord

Autor: Benjamin Pontiller, Clara Pérez-Martínez, Carina Bunse, Christofer M. G. Osbeck, José M. González, Daniel Lundin, Jarone Pinhassi

Publikováno v: mSystems, Vol 6, Iss 6 (2021)

ABSTRACT A considerable fraction of organic matter derived from photosynthesis in the euphotic zone settles into the ocean’s interior and, as it progresses, is degraded by diverse microbial consortia that utilize a suite of extracellular enzymes an

Labile Dissolved Organic Matter Compound Characteristics Select for Divergence in Marine Bacterial Activity and Transcription

Autor: Benjamin Pontiller, Sandra Martínez-García, Daniel Lundin, Jarone Pinhassi

Publikováno v: Frontiers in Microbiology, Vol 11 (2020)

Bacteria play a key role in the planetary carbon cycle partly because they rapidly assimilate labile dissolved organic matter (DOM) in the ocean. However, knowledge of the molecular mechanisms at work when bacterioplankton metabolize distinct compone

Dynamics of Baltic Sea phages driven by environmental changes

Publikováno v: Hoetzinger, M, Nilsson, E, Arabi, R, Osbeck, C M G, Pontiller, B, Hutinet, G, Bayfield, O W, Traving, S, Kisand, V, Lundin, D, Pinhassi, J, Middelboe, M & Holmfeldt, K 2021, ' Dynamics of Baltic Sea phages driven by environmental changes ', Environmental Microbiology, vol. 23, no. 8, pp. 4576-4594 . https://doi.org/10.1111/1462-2920.15651

Phage predation constitutes a major mortality factor for bacteria in aquatic ecosystems, and thus, directly impacts nutrient cycling and microbial community dynamics. Yet, the population dynamics of specific phages across time scales from days to mon
