Regulation and regeneration in the ctenophore Mnemiopsis leidyi.
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. Under certain conditions, however, these deficient ani...
متن کاملSpecific immune priming in the invasive ctenophore Mnemiopsis leidyi.
Specific immune priming enables an induced immune response upon repeated pathogen encounter. As a functional analogue to vertebrate immune memory, such adaptive plasticity has been described, for instance, in insects and crustaceans. However, towards the base of the metazoan tree our knowledge about the existence of specific immune priming becomes scattered. Here, we exposed the invasive ctenop...
متن کاملSHORT COMMUNICATION Carbon content of Mnemiopsis leidyi eggs and specific egg production rates in northern Europe
The comb jelly Mnemiopsis leidyi is considered to be a successful invasive species, partly due to its high reproduction potential. However, due to the absence of direct carbon measurements of eggs, specific reproduction rates remain uncertain. We show that egg carbon is 0.22+ 0.02 mg C and up to 21 times higher than previously extrapolated. With maximum rates of 11 232 eggs ind day, largest ani...
متن کاملEvolution of the TGF-β Signaling Pathway and Its Potential Role in the Ctenophore, Mnemiopsis leidyi
The TGF-β signaling pathway is a metazoan-specific intercellular signaling pathway known to be important in many developmental and cellular processes in a wide variety of animals. We investigated the complexity and possible functions of this pathway in a member of one of the earliest branching metazoan phyla, the ctenophore Mnemiopsis leidyi. A search of the recently sequenced Mnemiopsis genome...
متن کاملEffects of low dissolved oxygen on zooplankton predation by the ctenophore Mnemiopsis leidyi
The occurrence of low dissolved oxygen (DO), caused by vertical stratification and excess nutrient inputs, is an important and widely occurring physical feature in aquatic systems. Because some gelatinous species, such as the lobate ctenophore Mnemiopsis leidyi are more tolerant of low DO concentrations than their prey and competitors, hypoxia may have profound effects on trophic interactions. ...
