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

Genomic Insights Into Species Delimitation and the Evolutionary History of Mimetic <i>Aletis</i> Moths (Lepidoptera, Geometridae) in the Afrotropics. [PDF]

Ecol Evol
We investigated the evolutionary history and species boundaries of diurnal Aletis moths in the Afrotropics using mitochondrial DNA and genome‐wide SNP data. Our results support five distinct species, with divergence dating back to 0.9 million years ago, influenced by climate‐driven isolation and habitat variation.

Initial discovery of microplastic pollution in Mnemiopsis leidyi (Ctenophora: Lobata)

Water Biology and Security, 2023
The production of plastics has exponentially increased over time such that the observation of microplastics in the oceans has become a major concern given how frequently these particles and marine biota may interact.

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.

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 ...

Comparative algological and bacteriological examinations on biofilms developed on different substrata in a shallow soda lake [PDF]

, 2008
According to the European Water Framework Directives, benthic diatoms of lakes are a tool for ecological status assessment. In this study, we followed an integrative sample analysis approach, in order to find an appropriate substratum for the water ...

Population genomic structure of the gelatinous zooplankton species Mnemiopsis leidyi in its nonindigenous range in the North Sea [PDF]

, 2019
Nonindigenous species pose a major threat for coastal and estuarine ecosystems. Risk management requires genetic information to establish appropriate management units and infer introduction and dispersal routes. We investigated one of the most successful

The complete mitochondrial genome of the Ctenophore Beroe cucumis, a mitochondrial genome showing rapid evolutionary rates

Mitochondrial DNA. Part B. Resources, 2019
We described the complete mitochondrial genome of the Ctenophore Beroe cucumis, which is a circular molecule of 10,487 bp in length. The new mitochondrial genome comprised only 12 genes, making it one of the smallest animals’ mtDNA.

A sticky thicket of glue cells: A comparative morphometric analysis of colloblasts in 20 species of comb jelly (phylum Ctenophora)

Ciencias Marinas, 2020
Ctenophores in the class Tentaculata are distinct from Cnidarians in that they use sticky, not stinging, tentacles to capture and subdue their prey.
