Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

open access: yesThe Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.

Assessing the Diversity of New Zealand's Freshwater Copepods (Crustacea:Copepoda) using Mitochondrial DNA (COI) Sequences [PDF]

open access: yes, 2014
The diversity of New Zealand’s freshwater copepods has been largely understudied. In order to enhance our understanding of this taxon, I used the mitochondrial cytochrome c oxidase subunit one (COI) gene sequences to examine the diversity of two orders ...

The complex evolutionary history and phylogeography of Caridina typus (Crustacea: Decapoda): long-distance dispersal and cryptic allopatric species [PDF]

open access: yes, 2017
The evolutionary history of the old, diverse freshwater shrimp genus Caridina is still poorly understood, despite its vast distribution – from Africa to Polynesia.

Characterization and Phylogenetic Analysis of Chloroplast and Mitochondria Genomes from the Antarctic Polytrichaceae Species Polytrichum juniperinum and Polytrichum strictum

open access: yesDiversity, 2018
In this study, the organelle genomes of Polytrichum juniperinum Hedw. and Polytrichum strictum Menzies ex Brid. (Polytrichaceae, Bryophyta) from Antarctica were sequenced and compared with the plastomes of the model moss species Physcomitrella patens ...

Epidemiological Survey and Genomic Insights Into Ostreid Herpesvirus 1 Transmission in the Blood Clam Anadara broughtonii in China (2019–2025)

open access: yesAnimal Research and One Health, EarlyView.
Seven‐year surveillance reveals a cold‐adapted OsHV‐1 lineage in blood clams, with disease onset at 13°C—3–5°C lower than in oysters—and identifies asymptomatic carriers and facility effluent as key transmission routes. ABSTRACT Ostreid herpesvirus 1 (OsHV‐1) poses a major threat to bivalve aquaculture, but its impact on blood clams (Anadara ...

Long-Term Coexistence of Rotifer Cryptic Species

open access: yesPLoS ONE, 2011
Despite their high morphological similarity, cryptic species often coexist in aquatic habitats presenting a challenge in the framework of niche differentiation theory and coexistence mechanisms. Here we use a rotifer species complex inhabiting highly unpredictable and fluctuating salt lakes to gain insights into the mechanisms involved in stable ...

Graphite Co‐Intercalation Chemistry in Sodium‐Ion Batteries

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
Traditional intercalation chemistry in lithium‐ion batteries cannot allow sodium storage in graphite. The co‐intercalation chemistry changes the situation. It enables reversible and ultrafast sodium storage in graphite. Revisiting challenges and summarizing recent advances are of significant importance to exploit the full potential of graphite in ...

Molecular phylogenetic analysis of Peronosclerospora (Oomycetes) reveals cryptic species and genetically distinct species parasitic to maize

open access: yes, 2011
Downy mildews are amongst the most widespread and economically important pathogens of cultivated grasses in the tropics and subtropics. Despite their importance, molecular methods, particularly DNA sequence analysis, have rarely been applied to either ...
