Phylogeny as a proxy for ecology in seagrass amphipods: which traits are most conserved? [PDF]

open access: yes, 2013
Increasingly, studies of community assembly and ecosystem function combine trait data and phylogenetic relationships to gain novel insight into the ecological and evolutionary constraints on community dynamics.

18S-NemaBase: Curated 18S rRNA Database of Nematode Sequences

open access: yesJournal of Nematology, 2023
Nematodes are the most abundant and diverse animals on the planet but lack representation in biodiversity research. This presents a problem for studying nematode diversity, particularly when molecular tools (i.e., barcoding and metabarcoding) rely on ...

Crinoid phylogeny: a preliminary analysis (Echinodermata: Crinoidea) [PDF]

open access: yes, 2004
We describe the first molecular and morphological analysis of extant crinoid high-level inter-relationships. Nuclear and mitochondrial gene sequences and a cladistically coded matrix of 30 morphological characters are presented, and analysed by ...

Vibration analysis of a permanent magnet synchronous motor by a pole/slot combination

open access: yesAIP Advances, 2023
A sixteen-pole eighteen-slot (16p/18s) permanent magnet synchronous motor (PMSM) developed in Korea Electrotechnology Research Institute (KERI) for a vertical articulated robot is chosen as a reference model, and other two pole/slot combinations (20p/18s,

Two Species of Canine Babesia in Australia: Detection and Characterization by PCR [PDF]

open access: yes, 2003
The haemoprotozoan Babesia canis has been recognized in Australia for many years, and a second, smaller species has recently been discovered. Amplification and sequencing of a partial region of the 18S small subunit ribosomal RNA (rRNA) gene enabled ...

Microbial Eukaryotes in Oil Sands Environments: Heterotrophs in the Spotlight

open access: yesMicroorganisms, 2019
Hydrocarbon extraction and exploitation is a global, trillion-dollar industry. However, for decades it has also been known that fossil fuel usage is environmentally detrimental; the burning of hydrocarbons results in climate change, and environmental ...

Free-living protozoa in two unchlorinated drinking water supplies identified by phylogenic analysis of 18S rRNA gene sequences [PDF]

open access: yes, 2009
Free-living protozoan communities in water supplies may include hosts for Legionella pneumophila and other undesired bacteria and also pathogens. This study aimed at identifying free-living protozoa in two unchlorinated groundwater supplies using ...

The nucleolar RNA methyltransferase Misu (NSun2) is required for mitotic spindle stability [PDF]

open access: yes, 2009
Myc-induced SUN domain–containing protein (Misu or NSun2) is a nucleolar RNA methyltransferase important for c-Myc–induced proliferation in skin, but the mechanisms by which Misu contributes to cell cycle progression are unknown.

Analysis of small and large subunit rDNA introns from several ectomycorrhizal fungi species.

open access: yesPLoS ONE, 2021
The small (18S) and large (28S) nuclear ribosomal DNA (rDNA) introns have been researched and sequenced in a variety of ectomycorrhizal fungal taxa in this study, it is found that both 18S and 28S rDNA would contain introns and display some degree ...
