Deoxymanoalides from the Nudibranch Chromodoris willani

Chemical and Pharmaceutical Bulletin, 2009
Two sesterterpenes, deoxymanoalide (1) and deoxysecomanoalide (2), were isolated from the nudibranch Chromodoris willani collected in Okinawa and their structures determined on the basis of spectroscopic data and chemical conversions. The mollusk feeds on a sponge containing manoalide (3) and secomanoalide (4) and is likely to biotransform them into 1 ...

Thermal tolerance plasticity under stress: the impact of a marine heatwave and bleaching in the various life stages of Berghia stephanieae

Frontiers in Marine Science
With the increasing intensity and duration of marine heatwaves (MHW), there has been a corresponding rise in bleaching events. These events cause severe ecological impacts, yet most studies have focused on directly impacted or economically important ...

Oxygenated Sesquiterpenes From the Indo-Pacific Nudibranch : Structure Revision of Pu’ulenal

Natural Product Communications, 2021
Seven oxygenated sesquiterpenes 1 to 7 each with a drimane framework were isolated from an organic extract of the nudibranch Ardeadoris rubroannulata collected from Eastern Australia.

Genetic Evidence Confirms That the Porostomate Nudibranch Dendrodoris gunnamatta Allan, 1932 Is a Morphotype of Dendrodoris krusensternii (Gray, 1850) (Gastropoda: Nudibranchia)

Taxonomy, 2021
Conspecificity of the morphologically-similar, sympatric nudibranch species Dendrodoris gunnamatta (Allen, 1932) and Dendrodoris krusensternii (Gray, 1850) was tested using sequences of the mitochondrial COI gene.

Green Sea Turtle Recruitment in the Eastern North Pacific: Patterns Identified Using Geochemical Signatures in Bones

Ecology and Evolution, Volume 16, Issue 1, January 2026.
We present vital life‐history and demographic data including the oceanic stage duration, timing of ontogenetic habitat shifts, and multi‐year foraging patterns of eastern North Pacific green sea turtles found in Southern California. The findings were obtained by analyzing sea turtle bones (age and growth via skeletochronology; and habitat and diet via ...

Cold Seep Communities in the Sea of Japan Are Species‐Poor and Dominated by a New Species of Provannid Snail

Journal of Zoological Systematics and Evolutionary Research, Volume 2026, Issue 1, 2026.
The Sea of Japan is a semi‐enclosed marginal sea in the northwestern Pacific whose bathyal communities exhibit a depauperate species diversity due to anoxic events during the last glacial maximum. Cold seeps associated with chemosynthetic ecosystems were discovered in this region over three decades ago, yet their fauna have not been characterised. Here,

First true brackish-water nudibranch mollusc provides new insights for phylogeny and biogeography and reveals paedomorphosis-driven evolution.

PLoS ONE, 2018
A unique example of brackish water fjord-related diversification of a new nudibranch genus and species Bohuslania matsmichaeli gen. n., sp. n. is presented. There are only few previously known brackish-water opisthobranchs and B. matsmichaeli gen. n., sp.

Changing bryozoan fauna in Otago Harbour reflects growing urbanisation and globalisation

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 957-978, December 2025.
ABSTRACT A comparison between historic reports dating from 1884 (78 records of 35 species) to the bryozoan fauna present today (98 colonies of 14 species) reveals considerable faunal change in Otago Harbour / Te Wai Ōtākou (45° 50'S 170° 38'E) in Dunedin, east coast of South Island, Aotearoa New Zealand.

Near‐seabed sediment dynamics and fluxes on Chatham Rise, the effects of seabed disturbance, and implications for deep‐sea bottom trawling and seabed mining

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1460-1495, December 2025.
ABSTRACT Anthropogenic impacts are increasingly affecting deep‐sea environments, including seafloor sediment disturbances by bottom trawling and seafloor mining. Fieldwork in the ‘Resilience Of Benthic Ecosystems to Sedimentation’ (ROBES) project were conducted in 2018–2020 on the 400 m‐deep Chatham Rise crest, eastern Aotearoa New Zealand.
