Coral Disease and Health Workshop: Coral Histopathology II [PDF]

, 2007
The health and continued existence of coral reef ecosystems are threatened by an increasing array of environmental and anthropogenic impacts. Coral disease is one of the prominent causes of increased mortality among reefs globally, particularly in the ...

Ancient Venom Systems: A Review on Cnidaria Toxins

Toxins, 2015
Cnidarians are the oldest extant lineage of venomous animals. Despite their simple anatomy, they are capable of subduing or repelling prey and predator species that are far more complex and recently evolved. Utilizing specialized penetrating nematocysts,

Environmental DNA Documents Ecosystem‐Wide Biodiversity Within the Marine Protected Area Stellwagen Bank National Marine Sanctuary

Environmental DNA, Volume 7, Issue 3, May–June 2025.
Three marker genes targeting prokaryotic, eukaryotic, and vertebrate diversity were used to assess biodiversity within Stellwagen Bank National Marine Sanctuary. High levels of biodiversity were seen across the sampled area, with distinct communities across surface water, bottom water, and sediment.

Distinct mechanisms underlie oral vs aboral regeneration in the cnidarian Hydractinia echinata

eLife, 2015
Cnidarians possess remarkable powers of regeneration, but the cellular and molecular mechanisms underlying this capability are unclear. Studying the hydrozoan Hydractinia echinata we show that a burst of stem cell proliferation occurs following ...

Mechanisms and Drivers for the Establishment of Life Cycle Complexity in Myxozoan Parasites

Biology, 2020
It is assumed that complex life cycles in cnidarian parasites belonging to the Myxozoa result from incorporation of vertebrates into simple life cycles exploiting aquatic invertebrates.

Medusan Morphospace: Phylogenetic Constraints, Biomechanical Solutions, and Ecological Consequences [PDF]

, 2008
Medusae were the earliest animals to evolve muscle-powered swimming in the seas. Although medusae have achieved diverse and prominent ecological roles throughout the world\u27s oceans, we argue that the primitive organization of cnidarian muscle tissue ...

A Long‐Term Ecological Research Data Set From the Marine Genetic Monitoring Program ARMS‐MBON 2018–2020

Molecular Ecology Resources, Volume 25, Issue 4, May 2025.
ABSTRACT Molecular methods such as DNA/eDNA metabarcoding have emerged as useful tools to document the biodiversity of complex communities over large spatio‐temporal scales. We established an international Marine Biodiversity Observation Network (ARMS‐MBON) combining standardised sampling using autonomous reef monitoring structures (ARMS) with ...
