New Actinophage Species

open access: yesIntervirology, 1985
All actinophages of known morphology are tailed. From 305 phages surveyed, 4 belong to the Myoviridae family, 283 to the Siphoviridae, and 18 to the Podoviridae (two morphotypes each). 58 of 139 actinophages described since 1976 are classified in this report, and the earlier phage descriptions are updated. Nine new species and type viruses are proposed,

Plastome phylogenomic analysis reveals evolutionary divergences of Polypodiales suborder Dennstaedtiineae

open access: yesBMC Plant Biology, 2022
Background Polypodiales suborder Dennstaedtiineae contain a single family Dennstaedtiaceae, eleven genera, and about 270 species, and include some groups that were previously placed in Dennstaedtiaceae, Hypolepidaceae, Monachosoraceae, and Pteridaceae ...

Taxonomy and Phylogeny of Cystolepiota (Agaricaceae, Agaricales): New Species, New Combinations and Notes on the C. seminuda Complex

open access: yesJournal of Fungi, 2023
Species of Cystolepiota are known as diminutive lepiotaceous fungi with a worldwide distribution. Previous studies revealed that Cystolepiota is not monophyletic and preliminary DNA sequence data from recent collections suggested that several new species

A new species in the major malaria vector complex sheds light on reticulated species evolution

open access: yesScientific Reports, 2019
Complexes of closely related species provide key insights into the rapid and independent evolution of adaptive traits. Here, we described and studied Anopheles fontenillei sp.n., a new species in the Anopheles gambiae complex that we recently discovered ...

A pneumonia outbreak associated with a new coronavirus of probable bat origin

open access: yesNature, 2020
Since the outbreak of severe acute respiratory syndrome (SARS) 18 years ago, a large number of SARS-related coronaviruses (SARSr-CoVs) have been discovered in their natural reservoir host, bats1–4.

New Species of Agaricales [PDF]

open access: yesMycobiology, 2009
Clitocybe alboinfundibulliforme sp. nov. is widely distributed in Korea. Volvariella koreana sp. nov. is rarely distributed in Korea. These taxa were occasionally found together at the same place. Both of these species seem to be associated with each other. These two species are fully described and illustrated in this paper.

Biofilms associated with ship submerged surfaces: implications for ship biofouling management and the environment

open access: yesFrontiers in Marine Science, 2023
Biofouling (including initial microbial biofilms) of submerged ship surfaces can directly impact vessel operations, leading to increases in fuel usage, greenhouse gas emissions, and the likelihood of non-indigenous species (NIS) transfer and impacts ...

High throughput ANI analysis of 90K prokaryotic genomes reveals clear species boundaries

open access: yesNature Communications, 2017
A fundamental question in microbiology is whether there is continuum of genetic diversity among genomes, or clear species boundaries prevail instead. Whole-genome similarity metrics such as Average Nucleotide Identity (ANI) help address this question by ...
