Prolific Origination of Eyes in Cnidaria with Co-option of Non-visual Opsins.

Current Biology, 2018
Animal eyes vary considerably in morphology and complexity and are thus ideal for understanding the evolution of complex biological traits [1]. While eyes evolved many times in bilaterian animals with elaborate nervous systems, image-forming and simpler ...

Benthic megafauna and the functioning of macroalgal forests and urchin barrens

Oikos, EarlyView.
Two temperate rocky reef food‐web models, representing the trophic diversity of the Mediterranean rocky reef communities, were built for the two stable states: macroalgal forests and barren grounds, which are characterized by opposite amounts of erect macroalgal biomass.

Novel diversity in mitochondrial genomes of deep-sea Pennatulacea (Cnidaria: Anthozoa: Octocorallia)

Mitochondrial DNA. Part A, DNA mapping, sequencing, and analysis, 2019
We present the first documented complete mitogenomes of deep-sea Pennatulacea, representing nine genera and eight families. These include one species each of the deep-sea genera Funiculina, Halipteris, Protoptilum and Distichoptilum, four species each of

Incorporating environmental DNA metabarcoding for improved benthic biodiversity and habitat mapping

Remote Sensing in Ecology and Conservation, EarlyView.
Seafloor imagery is commonly used to collect information about the distribution of benthic organisms in order to generate habitat and biodiversity maps. Recent advances in genomics (e.g., environmental DNA; eDNA) show potential to complement video surveys for habitat mapping, but there have been few examples testing this.

β-Catenin–dependent mechanotransduction dates back to the common ancestor of Cnidaria and Bilateria

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Besides genetic regulation, mechanical forces have been identified as important cues in numerous developmental processes. Mechanical forces can activate biochemical cascades in a process called mechanotransduction.

Cabomba caroliniana and Schoenoplectus californicus as Antifouling Candidates: Anti‐Attachment and Toxicological Effects in Aurelia coerulea (Cnidaria, Scyphozoa)

Environmental Toxicology, EarlyView.
ABSTRACT Biofouling on artificial surfaces in aquatic ecosystems leads to significant economic losses. Current antifouling paints, while effective, often harm the aquatic environment. This study explores ecologically safe antifouling alternatives derived from plants, focusing on the aquatic macrophytes Cabomba caroliniana (CC) and Schoenoplectus ...

Complete mitochondrial genome of Callogorgia cf. gracilis (Octocorallia: Calcaxonia: Primnoidae)

Mitochondrial DNA. Part B. Resources, 2019
We report the first complete mitochondrial genome of Callogorgia. Callogorgia cf. gracilis isolate DFH32_518B was collected by a remotely operated vehicle at 98 m on McGrail Bank (27.9840725°N, 92.604242°W). The complete mitogenome is 18,937 bp (27.8% A,

Additional notes on Clathrozoella drygalskii (Vanhöffen, 1910) (Cnidaria, Hydrozoa)

Scientia Marina, 2000
Study of the material of Clathrozoella drygalskii (Vanhöffen, 1910), a hydroid initially referred to the thecate hydroids but probably better classified in athecate hydroids along with such families as Hydractiniidae and Solanderiidae, has been continued

Deep-sea coral distribution on seamounts, oceanic islands, and continental slopes in the Northeast Atlantic [PDF]

, 2007
A database of deep-water (\u3e 200 m) antipatharians, scleractinians, and gorgonians has been assembled for the NE Atlantic to determine what their distribution and diversity was before coral habitats became heavily impacted by bottom fishing gear ...

Evolution and development of Brain Networks: From Caenorhabditis elegans to Homo sapiens

, 2011
Neural networks show a progressive increase in complexity during the time course of evolution. From diffuse nerve nets in Cnidaria to modular, hierarchical systems in macaque and humans, there is a gradual shift from simple processes involving a limited ...
