TL;DR: It is indicated that there may have been at least four independent losses of the flagellum in the kingdom Fungi, and the enigmatic microsporidia seem to be derived from an endoparasitic chytrid ancestor similar to Rozella allomycis, on the earliest diverging branch of the fungal phylogenetic tree.

TL;DR: In this article, the authors describe the two interwoven paths by which citizen science can improve conservation efforts, natural resource management, and environmental protection, and describe the investments needed to create a citizen science program.

TL;DR: A 6-gene, 420-species maximum-likelihood phylogeny of Ascomycota, the largest phylum of Fungi, and a phylogenetic informativeness analysis of all 6 genes and a series of ancestral character state reconstructions support a terrestrial, saprobic ecology as ancestral are presented.
Journal ArticleDOI
Eukaryotic organisms in Proterozoic oceans
TL;DR: Focus on character evolution permits inferences about the innovations in cell biology and development that underpin the taxonomic and morphological diversification of eukaryotic organisms.
Journal ArticleDOI
Reactive oxygen species and development in microbial eukaryotes.
TL;DR: This work shows that manipulation of reactive species, as strategy to regulate cell differentiation, is ubiquitous in eukaryotes and suggests that such strategy was selected early in evolution.
