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?

open access: yesEvoDevo, 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

open access: yesJournal 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 ...

Sound scattering by the gelatinous zooplankters Aequorea victoria and Pleurobrachia bachei

open access: yesDeep 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.

Role of advection in the distribution and abundance of Pleurobrachia pileus in Kiel Bight

open access: yesMarine Ecology Progress Series, 1987
Abundance of the ctenophore Pleurobrachia pileus and s h t y were studied at a station in the western Kiel Bight from January to July 1981. Results suggest that variations of the ctenophore stock were primarily caused by advection and did not reflect the biological population cycle of this species.
