A Silurian armoured aplacophoran and implications for molluscan phylogeny
TLDR
Phylogenetic analysis indicates that the Kulindroplax perissokomos gen. et sp. Expand

TLDR
The results imply that crown-group molluscan synapomorphies include serial repetition, the presence of a foot, a mineralized scleritome and a creeping rather than worm-like mode of life. Expand
The Continuing Debate on Deep Molluscan Phylogeny: Evidence for Serialia (Mollusca, Monoplacophora + Polyplacophora)
TLDR
A new molecular clock indicates that molluscs had a terminal Precambrian origin with rapid divergence of all eight extant classes in the Cambrian, and the recovery of Serialia as a derived, Late Cambrian clade is potentially in line with the stratigraphic chronology of morphologically heterogeneous early mollusc fossils. Expand
A tale of two chitons: is habitat specialisation linked to distinct associated bacterial communities?
TLDR
Investigation of the feeding strategies of two species, Leptochiton boucheti and Nierstraszella lineata, recovered on sunken wood sampled in the western Pacific suggests that the distinct associations with bacterial partners are linked to niche specialisations of the two species. Expand
Molecular phylogenies support homoplasy of multiple morphological characters used in the taxonomy of Heteroscleromorpha (Porifera: Demospongiae).
TLDR
The results show that axially condensed skeletons, asters, acanthostyles, and sigmata are all homoplasious characters, which explains much of the incongruence between molecular-based and morphology-based phylogenies. Expand
Effects of conventional and biodegradable microplastics on a marine ecosystem engineer (Arenicola marina) and sediment nutrient cycling.
TLDR
Overall, both conventional and biodegradable microplastics in sandy sediments can affect the health and behaviour of lugworms and directly or indirectly reduce primary productivity of these habitats. Expand
A chiton without a foot
TLDR
Phthipodochiton thraivensis presents an apparent mosaic of aplacophoran and polyplacphoran features and as such will inform the understanding of the relationship between these groups of extant molluscs. Expand
Evolution in the deep sea: a combined analysis of the earliest diverging living chitons (Mollusca : Polyplacophora : Lepidopleurida)
TLDR
The results show that Lepidopleurida is unambiguously monophyletic, and the nine genera fall into five distinct clades, which partly support the current view of polyplacophoran taxonomy and suggest two separate clades independently inhabiting sunken wood substrates in the south-west Pacific. Expand
Chiton phylogeny (Mollusca : Polyplacophora) and the placement of the enigmatic species Choriplax grayi (H. Adams & Angas)
TLDR
Multigene analysis of standard nuclear and mitochondrial markers demonstrates that the topology of the order Chitonida is divided into four clades, which have also been recovered in previous studies: Mopalioidea is sister to Cryptoplacoidea, forming a clade Acanthochitonina. Expand
Anthropogenic Noise Affects Behavior across Sensory Modalities
TLDR
The results provide experimental evidence that anthropogenic noise has a marked effect on the behavior of species that are not reliant on acoustic communication, and interference in one sensory channel, in this case the acoustic one, affects signaling in other sensory channels. Expand
