Potential pathways of invasion and dispersal of Mnemiopsis leidyi A. Agassiz 1865 in the Baltic Sea [PDF]

, 2010
The rapid spread of Mnemiopsis leidyi across the entire Baltic Sea after its first observation in 2006 gave rise to the question of its invasion pathway and the possible vector of its transport. To investigate pathways of M.

Comparative study of Hippo pathway genes in cellular conveyor belts of a ctenophore and a cnidarian

EvoDevo, 2016
Background The Hippo pathway regulates growth rate and organ size in fly and mouse, notably through control of cell proliferation. Molecular interactions at the heart of this pathway are known to have originated in the unicellular ancestry of metazoans ...

Independent specialisation of myosin II paralogues in muscle vs. non-muscle functions during early animal evolution: a ctenophore perspective

BMC Evolutionary Biology, 2012
Background Myosin II (or Myosin Heavy Chain II, MHCII) is a family of molecular motors involved in the contractile activity of animal muscle cells but also in various other cellular processes in non-muscle cells.

Atlas of Neuromuscular Organization in the Ctenophore, Pleurobrachia bachei (A. Agassiz, 1860) [PDF]

, 2018
Enigmatic ctenophores are descendants of one of the earliest branching metazoan lineage. Their nervous systems are equally elusive. The lack of convenient neurogenic molecules and neurotransmitters suggests an extensive parallel evolution and independent origins of neurons and synapses.

Nuclear receptors from the ctenophore Mnemiopsis leidyi lack a zinc-finger DNA-binding domain: lineage-specific loss or ancestral condition in the emergence of the nuclear receptor superfamily?

EvoDevo, 2011
Background Nuclear receptors (NRs) are an ancient superfamily of metazoan transcription factors that play critical roles in regulation of reproduction, development, and energetic homeostasis.

Seasonal Dynamics and Trophic Impact of Mesozooplankton in the Shannon River Estuary System, Ireland

Journal of Marine Science and Engineering
Mesozooplankton (netplankton > 250 µm) were sampled during nine cruises over one year at three stations in the Shannon estuary system, Ireland. A net with three mesh sizes was used to capture a wider range of plankton sizes than a standard single-mesh ...

The evolution of the dystroglycan complex, a major mediator of muscle integrity [PDF]

, 2015
Basement membrane (BM) extracellular matrices are crucial for the coordination of different tissue layers. A matrix adhesion receptor that is important for BM function and stability in many mammalian tissues is the dystroglycan (DG) complex.

Sound scattering by the gelatinous zooplankters Aequorea victoria and Pleurobrachia bachei

Deep Sea Research Part II: Topical Studies in Oceanography, 1998
Abstract Target strengths were determined for individual Aequorea victoria and Pleurobrachia bachei using separate 200, 420 and 1,000 kHz transducers in an enclosure deployed off the dock of the Friday Harbor Laboratories in northern Puget Sound, Washington, USA.
