Metazoan Diversity and Its Drivers: An eDNA Survey in the Pacific Gateway of a Changing Arctic Ocean

open access: yesEnvironmental DNA, Volume 7, Issue 2, March/April 2025.
In the face of climate change, organisms must adapt or shift their ranges to survive. Our study conducted the first COI marker‐based eDNA survey in the Pacific Gateway of the Arctic Ocean, analyzing seawater samples from the Bering Strait and Chukchi Sea.

ECOLOGICL ASPECTS OF THE MORPHODYNAMICS OF SOME HYDROZOA [PDF]

open access: yesAmerican Zoologist, 1965
The specific architecture of a Hydroid polyp or a colony is, morphologically speaking, not a stable entity, because it is subjected to an incessant turnover and renewal at both cellular and higher levels. A continuous morphogenetic activity is in many cases (e.g., Hydra ) necessary for the maintenance of the shape and size of the individual polyp ...

Marine benthic flora and fauna of Gourdon Bay and the Dampier Peninsula in the Kimberley region of North-Western Australia [PDF]

open access: yes, 2011
Surveys undertaken to characterise the marine benthic habitats along the Dampier Peninsula and further south at Gourdon Bay in the Kimberley region of Western Australia were augmented with epibenthic sled sampling of soft and hard bottom habitats.

Microsatellite abundance across the Anthozoa and Hydrozoa in the phylum Cnidaria [PDF]

open access: yes, 2014
Background: Microsatellite loci have high mutation rates and thus are indicative of mutational processes within the genome. By concentrating on the symbiotic and aposymbiotic cnidarians, we investigated if microsatellite abundances follow a phylogenetic ...

A Morphospace Exploration Using a General Model of Development Reveals a Basic Set of Morphologies for Early Animal Development and Evolution

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 2, Page 45-58, March 2025.
This work used the model EmbryoMaker to explore the most basic set of morphologies that can be produced from spherical initial conditions by activating cell properties and behaviors in simple genetic territories. We found five possible morphogenetic transformations: invagination, evagination, elongation, condensation and anisotropic growth.

Orientiertes Wachstum beiMillepora dichotoma (Hydrozoa) [PDF]

open access: yesHelgoländer Wissenschaftliche Meeresuntersuchungen, 1974
1. An der Westkuste des Golfes von Akaba wurde an 3 verschiedenen Probeorten die Facherorientierung vonMillepora dichotoma untersucht, wobei jede Probenflache aus drei gleichgrosen Teilflachen bestand. Die Tiefenausdehnung des Transekts wurde durch die Tiefenbegrenzung der Milleporiden bestimmt. 2.

In situ predation of Boops boops (Linnaeus, 1758) on the rare hydrozoan, Geryonia proboscidalis (Forsskål, 1775), in the Aegean Sea, Turkey

open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2017
Most data of fish feeding on cnidarians were obtained from the studies on gut contents of the predators rather than in situ observations. The feeding observation of Boops boops on Geryonia proboscidalis was observed in September 2013, in Sığacık Bay, the

Functional Characteristics of Nematocysts Found on the Scyphomedusa Cyanea Capillata [PDF]

open access: yes, 2007
Although prey capture by cnidarians is mediated through nematocysts, their influence on prey selection by cnidarians remains poorly documented. The difficulty in visualizing nematocyst–prey interactions remains the chief obstacle to understanding how the

A Novel Mode of Colony Formation in a Hydrozoan through Fusion of Sexually Generated Individuals [PDF]

open access: yes, 2012
SummaryColoniality, as displayed by most hydrozoans, is thought to confer a size advantage in substrate-limited benthic marine environments and affects nearly every aspect of a species' ecology and evolution [1,2].

Large‐Scale Environmental Drivers of Kelp Biofouling Based on Literature Data

open access: yesReviews in Aquaculture, Volume 17, Issue 2, March 2025.
Our findings from data compiled from a systematic literature review and databases of marine data show that kelp biofouling species are linked to environmental conditions and specifically temperature for bryozoans, salinity for gastropods, and the type of kelp population (wild vs. not wild) for hydrozoans.
