Evolution of the northern rockweed, Fucus distichus, in a regime of glacial cycling: implications for benthic algal phylogenetics [PDF]

, 2015
Northern hemisphere rockweeds (Fucus) are thought to have evolved in the North Pacific and then spread to the North Atlantic following the opening of the Bering Strait. They have dispersed and widely speciated in the North Atlantic and its tributary seas.

Fingerprinting Arctic and North Atlantic Macroalgae with eDNA – Application and perspectives

Environmental DNA, Volume 4, Issue 2, Page 385-401, March 2022., 2022
Macroalgae are key primary producers in Arctic and North Atlantic coastal ecosystems and tracing their fate is important to understand their role in higher trophic levels and carbon sequestration. Here, we study the application and perspectives in applying metabarcoding methods for this purpose.

Exhaustive reanalysis of barcode sequences from public repositories highlights ongoing misidentifications and impacts taxa diversity and distribution

Molecular Ecology Resources, Volume 22, Issue 1, Page 86-101, January 2022., 2022
Abstract Accurate species identification often relies on public repositories to compare the barcode sequences of the investigated individual(s) with taxonomically assigned sequences. However, the accuracy of identifications in public repositories is often questionable, and the names originally given are rarely updated.

Evolution of life cycles and reproductive traits: Insights from the brown algae

Journal of Evolutionary Biology, Volume 34, Issue 7, Page 992-1009, July 2021., 2021
The brown algae are a eukaryotic lineage that evolved complex life cycles independently of plants and animals, with several instances of haploid‐dominant, diploid‐dominant and equally dominant life cycles. We reconstructed the history of life cycle evolution throughout the brown algae alongside other reproductive traits, such as the sex‐determination ...

A trophic cascade facilitates native habitat providers within assemblages of multiple invasive marine species

Ecosphere, Volume 12, Issue 6, June 2021., 2021
Abstract Anthropogenically influenced habitats are becoming increasingly impacted by multiple invasive species that can regionally control main ecological processes and functions. Management requires predictions of invasive species’ effects, but multiple invasions may cause unpredictable outcomes, for example, synergistic impacts or interactions among ...

Analysis of sexual phenotype and prezygotic fertility in natural populations of Fucus spiralis, F. vesiculosus (Fucaceae, Phaeophyceae) and their putative hybrids [PDF]

, 2014
In the genus Fucus, the character dioecy/hermaphroditism has undergone multiple state changes and hybridization is possible between taxa with contrasting mating systems, e.g. between the dioecious Fucus vesiculosus and the hermaphrodite F. spiralis.

Development and characterization of 35 single nucleotide polymorphism markers for the brown alga Fucus vesiculosus [PDF]

, 2011
We characterized 35 single nucleotide polymorphism (SNP) markers for the brown alga Fucus vesiculosus. Based on existing Fucus Expressed Sequence Tag libraries for heat and desiccation-stressed tissue, SNPs were developed and confirmed by re-sequencing

Photopolarization of Fucus zygotes is determined by time sensitive vectorial addition of environmental cues during axis amplification [PDF]

, 2015
Fucoid zygotes have been extensively used to study cell polarization and asymmetrical cell division. Fertilized eggs are responsive to different environmental cues (e.g., light, gravity) for a long period before the polarity is fixed and the cells ...
