Precious Coral Fisheries of Hawaii and the U.S. Pacific Islands [PDF]

open access: yes, 1993
The precious coral fishery in Hawaii and the Western Pacific consists of one industry but two distinct and separate fisheries. The first is the harvest of black coral by scuba divers from depths of 30-100 m.

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.

Prioritising research on endocrine disruption in the marine environment: a global perspective

open access: yesBiological Reviews, Volume 101, Issue 2, Page 848-868, April 2026.
ABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.

Marine Invertebrate-Associated Bacteria In Coral Reef Ecosystems As A New Source Of Bioactive Compounds [PDF]

open access: yes, 2004
Coral reefs are the most species-rich environments in the oceans. Reefs cover 0.2% of the ocean’s area and yet they provide home to one-third of marine fishes and to tens of thousands of other species.

Morphological diversity of medusan lineages constrained by animal–fluid interactions [PDF]

open access: yes, 2007
Cnidarian medusae, commonly known as jellyfish, represent the earliest known animal taxa to achieve locomotion using muscle power. Propulsion by medusae requires the force of bell contraction to generate forward thrust.

Rapid Decreases and Performance Declines in Northeast Pacific Seamount Foundation Species Detected in an Oxygen Minimum Zone

open access: yesGlobal Change Biology, Volume 32, Issue 4, April 2026.
Across 12 long‐term monitoring sites on three Northeast Pacific seamounts, 163 of 844 cold‐water coral and sponge individuals were lost between surveys 3–5 years apart, with abundance declining at five sites and condition (i.e., health) declining at nine.

Planuloid budding from a cutting plane of polyp stalk of Cassiopea sp.(Cnidaria, Scyphozoa) [PDF]

open access: yes, 2015
Cassiopea polyps that appeared in culture vessels of Turritopsis sp. polyps at the Seto Marine Biological Laboratory, Kyoto University in 2014 were experimentally amputated their stalks from the calyxes.

Evaluating the possible role of bottom currents and internal waves in shaping seafloor morphology in a mesophotic reef

open access: yesSedimentology, Volume 73, Issue 3, Page 593-619, April 2026.
ABSTRACT Mesophotic reefs are located in low light conditions which, depending on the region, are usually found in water depths greater than ~30 m. They are less affected by ocean warming than reefs found in shallower water depths and thus might become increasingly important for the sustainability of marine biodiversity.

Benthic communities associated to Thalassia testudinum (Hydrocharitaceae) at three localities of Morrocoy National Park, Venezuela

open access: yesRevista de Biología Tropical, 1999
The benthic community associated with the turtlegrass Thalassia testudinum beds was analized at three localities of Morrocoy National Park, Venezuela.

Predicting oxygen thresholds of marine taxa to improve ecological forecasts

open access: yesEcography, Volume 2026, Issue 3, March 2026.
Species' ranges are shifting in response to increasing temperature and decreasing oxygen in coastal oceans. Predicting these shifts is limited by information on physiological oxygen thresholds and how they depend on temperature. Here we collate laboratory‐derived measurements of a common oxygen threshold, pcrit, for 148 animal species that span six ...
