Predator-Induced Vertical Behavior of a Ctenophore [PDF]

, 2012
Although many studies have focused on Mnemiopsis leidyi predation, little is known about the role of this ctenophore as prey when abundant in native and invaded pelagic systems. We examined the response of the ctenophore M.

A Screen for Gene Paralogies Delineating Evolutionary Branching Order of Early Metazoa

G3: Genes, Genomes, Genetics, 2020
The evolutionary diversification of animals is one of Earth’s greatest marvels, yet its earliest steps are shrouded in mystery. Animals, the monophyletic clade known as Metazoa, evolved wildly divergent multicellular life strategies featuring ciliated ...

Simonsenia aveniformis sp nov (Bacillariophyceae), molecular phylogeny and systematics of the genus, and a new type of canal raphe system [PDF]

, 2015
The genus Simonsenia is reviewed and S. aveniformis described as new for science by light and electron microscopy. The new species originated from estuarine environments in southern Iberia (Atlantic coast) and was isolated into culture. In LM, Simonsenia

Topology-dependent asymmetry in systematic errors affects phylogenetic placement of Ctenophora and Xenacoelomorpha

Science Advances, 2020
A data simulation approach shows that the contested origins of Ctenophora and Xenacoelomorpha are obscured by systematic errors. The evolutionary relationships of two animal phyla, Ctenophora and Xenacoelomorpha, have proved highly contentious ...

Environmental patterns and biomass distribution of gelatinous macrozooplankton. Three study cases in the South-western Atlantic Ocean

Scientia Marina, 2000
Periodic swarms or blooms of gelatinous macrozooplankton have a negative effect on many human activities such as tourism, fisheries, and industry, but for several reasons (sampling procedures, underestimation of their real abundance, etc.), they have ...

Questioning the rise of gelatinous zooplankton in the World's oceans [PDF]

, 2012
During the past several decades, high numbers of gelatinous zooplankton species have been reported in many estuarine and coastal ecosystems. Coupled with media-driven public perception, a paradigm has evolved in which the global ocean ecosystems are ...

Genomic data do not support comb jellies as the sister group to all other animals [PDF]

, 2015
Understanding how complex traits, such as epithelia, nervous systems, muscles, or guts, originated depends on a well-supported hypothesis about the phylogenetic relationships among major animal lineages.

Aggregations of a Sessile Ctenophore, Coeloplana sp., on Indo-West Pacific Gorgonians

Diversity, 2023
We document the benthic ctenophores Coeloplana sp. and Vallicula multiformis from Oman, extending their geographic range. A new Coeloplana species was found forming aggregations on gorgonians of two octocoral host genera, Melithaea and Euplexaura ...
