Diterpenoid Diversity across Land Plants

open access: yesHelvetica Chimica Acta, EarlyView.
Here we bridge the knowledge of diterpene chemical diversity, biosynthesis, and evolution from nonvascular mosses and liverworts to that known from vascular plants. ABSTRACT The diverse array of diterpenoid natural products stems from the ease of manipulating the promiscuity of diterpene cyclases.

Morphology of the First Zoeal Stage of the Shrimp Typton distinctus Chace, 1972: The Second for the Genus Typton O.G. Costa, 1844 After 100 Years

open access: yesActa Zoologica, EarlyView.
ABSTRACT The marine shrimp of the genus Typton are widely distributed, known to be associated with sessile organisms such as sponges. Information about this genus is limited, highlighting the scarcity of important features in its biology, including larval forms.

Marine Bifunctional Sphingolipids from the Sponge Oceanapia ramsayi

open access: yesMolecules, 2008
During the course of our continuing studies on marine natural lipid products,two known sphingolipids have been isolated for the first time from a specimen of themarine sponge Oceanapia ramsayi collected at Itampolo on the west coast of Madagascarin the ...

Comparative Multi‐Marker Environmental DNA Metabarcoding of Marine Metazoan Communities: Water vs. Sediment

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT This study investigates the metazoan biodiversity in the Southern Adriatic Sea using environmental DNA (eDNA) metabarcoding. Sediment and adjacent water samples were collected from three sites (one pristine, two impacted by human activities) at three distances from the coast across two seasons.

Barcoding‐Inferred Biodiversity of Shallow‐Water Indo‐Pacific Demosponges

open access: yesJournal of Biogeography, Volume 53, Issue 3, March 2026.
ABSTRACT Aim The Indo‐Pacific is the world's largest marine biogeographic region. It is characterised by different degrees of connectivity among its subregions and harbours the majority of demosponge species currently known to science. Comparisons between regional sponge faunas have been undertaken in the past, mostly based on morphological species ...

New species from the deep Pacific suggest that carnivorous sponges date back to the Early Jurassic [PDF]

open access: yes, 2008
Some deep-sea poecilosclerid sponges (Porifera) have developed a carnivorous feeding habit that is very surprising in sponges^1^. As shown by the typical morphology of their spicules, they most probably evolved from "normal sponges" under the ...

Examining Marine Assemblages Across an Inverse Salinity Gradient

open access: yesMolecular Ecology, Volume 35, Issue 6, March 2026.
ABSTRACT Salinity gradients and fluctuations can create a natural ecological filter, with few species tolerating salinity above 50 practical salinity units (PSUs). We investigated how an inverse salinity gradient affected marine community diversity and composition in Shark Bay, a remote hypersaline coastal embayment in Western Australia.

Similarity measures over refinement graphs [PDF]

open access: yes, 2016
Similarity also plays a crucial role in support vector machines. Similarity assessment plays a key role in lazy learning methods such as k-nearest neighbor or case-based reasoning.

Environmental DNA as a Tool for the Assessment of Coral (Anthozoa) Composition in the Chagos Archipelago

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
Environmental DNA (eDNA) metabarcoding using ITS2 markers reliably recovered 18 coral genera, with strong overlap but also complementary detections compared to benthic transect surveys. eDNA uniquely identified several cryptic genera, while some common genera were only recovered by traditional surveys, highlighting method‐specific biases.

Recovery at Morvin: SERPENT final report [PDF]

open access: yes, 2010
Recovery from disturbance is poorly understood in deep water, but the extent of anthropogenic impacts is becoming increasingly well documented. We used Remotely Operated Vehicles (ROV) to visually assess the change in benthic habitat after exploratory ...
