Substrate-Controlled Succession of Marine Bacterioplankton Populations Induced by a Phytoplankton Bloom
Blooming Succession Algal blooms in the ocean will trigger a succession of microbial predators and scavengers. Teeling et al. (p. 608) used a combination of microscopy, metagenomics, andExpand

A fluorometric method for the differentiation of algal populations in vivo and in situ
Fingerprints of excitation spectra of chlorophyll (Chl) fluorescence can be used to differentiate `spectral groups' of microalgae in vivo and in situ in, for example, vertical profiles within a fewExpand

Resilience of North Sea phytoplankton spring bloom dynamics: An analysis of long‐term data at Helgoland Roads
Analyzing one of the most extensive long-term data series in the North Sea, the Helgoland Roads time series, we investigated the changes in the factors that potentially drive phytoplankton bloomExpand

The warming trend at Helgoland Roads, North Sea: phytoplankton response
We combine the temperature and phytoplankton data from one of the longest aquatic data sets in history, the Helgoland Roads (North Sea, 54°11.3’N, 7°54.0’E) timeseries to evaluate the effects ofExpand

Bacterial community dynamics during the winter-spring transition in the North Sea.
Bacterioplankton dynamics at Helgoland Roads (54 degrees 11.3'N, 7 degrees 54.0'E) in the North Sea over the winter-spring transition were investigated. The bacterial community was analyzed andExpand

Picoeukaryotic Plankton Diversity at the Helgoland Time Series Site as Assessed by Three Molecular Methods
We analyzed picoeukaryote assemblages in the German Bight at the Helgoland time series site by sequencing cloned eukaryotic 18S rRNA genes in six genetic libraries plus one library from the OrkneyExpand

Global impacts of the 1980s regime shift
Abstract Despite evidence from a number of Earth systems that abrupt temporal changes known as regime shifts are important, their nature, scale and mechanisms remain poorly documented and understood.Expand

Recurring patterns in bacterioplankton dynamics during coastal spring algae blooms
A process of global importance in carbon cycling is the remineralization of algae biomass by heterotrophic bacteria, most notably during massive marine algae blooms. Such blooms can trigger secondaryExpand

Extraction of pigments and fatty acids from the green alga Scenedesmus obliquus (Chlorophyceae)
In this paper, the efficiency of pigment and fatty acid extraction from resistant algae using Scenedesmus obliquus as an example was examined. We found that adding quartz sand and solvent toExpand

Thalassiosira species (Bacillariophyceae, Thalassiosirales) in the North Sea at Helgoland (German Bight) and Sylt (North Frisian Wadden Sea) – a first approach to assessing diversity
Thalassiosira species are an important component of phytoplankton populations in pelagic waters around the islands of Helgoland and Sylt in the German North Sea. This taxonomic study revealed theExpand
