Coccolithophore life-cycle dynamics in a coastal Mediterranean ecosystem : seasonality and species-specific patterns
Coccolithophores (calcifying haptophyte algae) commonly exhibit a heteromorphic life cycle, alternating between morphologically distinct heterococcolith (diploid) and holococcolith (haploid) phases
High temperature decreases the PIC / POC ratio and increases phosphorus requirements in Coccolithus pelagicus (Haptophyta)
TLDR
It is suggested that a temperature increase may intensify P-limitation due to a higher P-requirement to maintain growth and POC production rates, possibly reducing abundances in a warmer ocean.
Eco-physiological adaptation shapes the response of calcifying algae to nutrient limitation
TLDR
The physiology of Helicosphaera carteri, a representative of the abundant but under-investigated flagellated functional group of coccolithophores, is investigated to suggest that local physiological adaptation can define the performance of this species under nutrient limitation.
Observations on the life cycle and ecology of Acanthoica quattrospina Lohmann from a Mediterranean estuary
TLDR
Observations on the life cycle and ecology of Acanthoica quattrospina Lohmann from a Mediterranean estuary show clear trends in the distribution and habits of these filter feeders across the Mediterranean.
Haptophyte Diversity and Vertical Distribution Explored by 18S and 28S Ribosomal RNA Gene Metabarcoding and Scanning Electron Microscopy
TLDR
The results contribute to link morphological and molecular data and 28S to 18S rRNA gene sequences of haptophytes without cultured representatives, and to improve metabarcoding methodology.
Cryptophyte bloom in a Mediterranean estuary: High abundance of Plagioselmis cf. prolonga in the Krka River estuary (eastern Adriatic Sea)
During the June 2010 survey of phytoplankton and physicochemical parameters in the Krka River estuary (eastern Adriatic Sea), a cryptophyte bloom was observed. High abundance of cryptophytes (maximum
Chytrid fungi distribution and co-occurrence with diatoms correlate with sea ice melt in the Arctic Ocean
TLDR
Investigation of the diversity and distribution patterns of fungi in relation to abiotic variables during one record sea ice minimum in 2012 and co-occurrence of chytrids with diatoms, key primary producers in these changing environments shows that chyTrid fungi are primarily encountered at sites influenced by sea ice melt.
Bacterial diversity across a highly stratified ecosystem: A salt-wedge Mediterranean estuary.
A 15-million-year-long record of phenotypic evolution in the heavily calcified coccolithophore Helicosphaera and its biogeochemical implications
TLDR
The phenotypic evolution in Helicosphaera is interpreted as a global, resource-limitation-driven selection for smaller cells, which appears to be a common adaptive trait among different coccolithophore lineages, from the warm and high-CO2 world of the middle Miocene to the cooler and low- CO2 conditions of the Pleistocene.
