The Phylum Cnidaria: A Review of Phylogenetic Patterns and Diversity 300 Years After Linnaeus [PDF]

open access: yes, 2007
Systema Naturae includes representatives of every major lineage of the animal phylum Cnidaria. However, Linnaeus did not classify the members of the phylum as is now done, and the diversity of the group is not well represented.

Density regulation inSarsia tubulosa (Hydrozoa) [PDF]

open access: yesHelgoländer Meeresuntersuchungen, 1980
The majority of wild-caughtSarsia tubulosa M. Sars medusae are less dense than the surrounding water. The bell ofS. tubulosa is the buoyant structure; the tentacles and manubrium sink if cut off from the bell.S. tubulosa individuals placed in dilute seawater sink initially but recover positive or neutral buoyancy and normal activity within a couple of ...

Testing the core–periphery hypothesis: a standardised multi‐phylum assessment of genetic diversity of marine coastal species

open access: yesEcography, Volume 2025, Issue 10, October 2025.
The core–periphery hypothesis (CPH) predicts that genetic diversity is greatest at the centre and lowest at the edges of a species' distribution because genetic diversity is a function of a species' abundance, which is also expected to be greatest at the centre and lowest at the edges of the distribution. Variants of the CPH include the ‘Ramped North' (

The Hydrozoa: a new classification in the light of old knowledge [PDF]

open access: yes, 2000
The Hydrozoa, on the basis of embryological, developmental and morphological features, are considered as a superclass of the phylum Cnidaria comprising three classes: the Automedusa (with the subclasses: Actinulidae, Narcomedusae and Trachymedusae ...

Mapping the Azores Marine Park Vulnerability to Temperature Changes

open access: yesDiversity and Distributions, Volume 31, Issue 10, October 2025.
ABSTRACT Aim Identifying highly vulnerable regions to climate change is increasingly incorporated in marine management planning given the expected redistribution of species with latitude, longitude, and depth following temperature changes. Here, we developed a spatially explicit vulnerability framework incorporating sensitivity, exposure, and adaptive ...

Prey Resource Utilization by Coexistent Hydromedusae from Friday Harbor, Washington, USA [PDF]

open access: yes, 2002
Prey selection patterns were quantified for a sympatric group of hydromedusae from Friday Harbor, WA. Selection patterns varied between species, but were largely replicable between sample dates and resembled dietary patterns found in similar studies from

Global Cold‐Water Coral Biodiversity Redistribution Under Projected Climate Change

open access: yesGlobal Change Biology, Volume 31, Issue 10, October 2025.
Cold‐water corals are key habitat providers in the world's oceans, yet their global distribution, diversity patterns, and vulnerability to climate change remain poorly understood. Our study mapped the global distribution of 741 cold‐water coral species and showed that while the overall coral biome may persist in the future, many species will shift ...

Biomass‐to‐volume ratio as a central continuous functional trait for marine zooplankton

open access: yesLimnology and Oceanography, Volume 70, Issue 9, Page 2673-2687, September 2025.
Abstract Gelatinous zooplankton are an important component of many ecosystems and important for ecosystem structure and carbon cycling. However, this group is generally not considered in biogeochemical models. Here we investigate the biomass‐to‐volume ratio as an underappreciated “master trait” that allows for the incorporation of a large diversity of ...
