The significance of silica structures in chromist microorganisms. [PDF]

, 2013
The silica is one of the most common elements in the Earth's crust. During erosion it is released in soluble form to the environment, where some organisms can accumulate the silica and incorporate it to their bodies by biosilicification process.

Biological invasions: a global assessment of geographic distributions, long‐term trends, and data gaps

Biological Reviews, Volume 100, Issue 6, Page 2542-2583, December 2025.
ABSTRACT Biological invasions are one of the major drivers of biodiversity decline and have been shown to have far‐reaching consequences for society and the economy. Preventing the introduction and spread of alien species represents the most effective solution to reducing their impacts on nature and human well‐being.

Metabolic pathway redundancy within the apicomplexan-dinoflagellate radiation argues against an ancient chromalveolate plastid

Communicative & Integrative Biology, 2016
The chromalveolate hypothesis presents an attractively simple explanation for the presence of red algal-derived secondary plastids in 5 major eukaryotic lineages: “chromista” phyla, cryptophytes, haptophytes and ochrophytes; and alveolate phyla ...

Taxonomic, phylogenetic and functional β‐diversity of stream algae is driven by the number of added nutrients and herbivory

Journal of Ecology, Volume 113, Issue 11, Page 3390-3405, November 2025.
Higher numbers of added nutrients (NAN) in treatment (T) relative to control (C) algal communities (1) and grazing (2) elevated taxonomic/phylogenetic nestedness (βNes) and functional gradient (βGra) components of β‐diversity. Herbivory favoured grazer‐resistant inferior competitors (2).
