Environmental Microbiology, Volume 25, Issue 11, Page 2321-2337, November 2023., 2023 This study reports for the first‐time the application of a digital PCR (dPCR) assay to target an alien species of a free‐living unicellular non‐pathogenic Eukaryote belonging to Foraminifera (Rhizaria). The number of DNA copies from our species‐specific dPCR assay highly correlates with morphospecies counts thus picking up the DNA signal from organisms

Limnology and Oceanography, Volume 68, Issue 9, Page 1982-1994, September 2023., 2023 Abstract Diatoms are among the most abundant phytoplankton that inhabit coastal ecosystems, forming large blooms that fuel coastal food webs. Although diatoms are often large and morphologically distinct, many are small or morphologically cryptic making it difficult to understand the temporal dynamics of whole diatom communities and the environmental ...

The sex lives of ctenophores: the influence of light, body size, and self-fertilization on the reproductive output of the sea walnut, Mnemiopsis leidyi [PDF]
PeerJ, 2016 Ctenophores (comb jellies) are emerging as important animals for investigating fundamental questions across numerous branches of biology (e.g., evodevo, neuroscience and biogeography).

Regulation and Regeneration in the Ctenophore Mnemiopsis leidyi
Developmental Biology, 2000 Lobate ctenophores (tentaculates) generally exhibit a remarkable ability to regenerate missing structures as adults. On the other hand, their embryos exhibit a highly mosaic behavior when cut into halves or when specific cells are ablated. These deficient embryos do not exhibit embryonic regulation, and generate incomplete adult body plans.

EvoDevo, 2016 Background An essential developmental pathway in sexually reproducing animals is the specification of germ cells and the differentiation of mature gametes, sperm and oocytes. The “germline” genes vasa, nanos and piwi are commonly identified in primordial

Stable Laboratory Culture System for the Ctenophore Mnemiopsis leidyi. [PDF]
Methods Mol BiolCtenophores are marine organisms attracting significant attention from evolutionary biology, molecular biology, and ecological research. Here, we describe an easy and affordable setup to maintain a stable culture of the ctenophore Mnemiopsis leidyi. The challenging delicacy of the lobate ctenophores can be met by monitoring the water quality, providing

LUMINESCENCE IN MNEMIOPSIS [PDF]
Journal of General Physiology, 1924 1. In the dark adapted Mnemiopsis, mechanical stimulation causes luminescence along the eight rows of paddle plates. The tactile receptors for this reaction lie only in the paddle plate rows, and are connected only longitudinally along these rows. 2.

A historical data on the seasonal density variation of phytoplankton, zooplankton and Mnemiopsis leidyi in the South Caspian Sea [PDF]
Caspian Journal of Environmental Sciences, 2022 The seasonal variation of phytoplankton, zooplankton (holoplankton) and ctenophore (Mnemiopsis leidyi) were investigated at eight transects from east to west in the South Caspian Sea. In spring (May), the most abundance of zooplankton was observed in the
