mnemiopsis การใช้

• Mnemiopsis feeds on fish eggs and the plankton that fish also eat.
• In the genome of " Mnemiopsis leidyi " ten genes encode photoproteins.
• Harbison has been studying the possible introduction of the butterfish to attack the Black Sea mnemiopsis.
• Mnemiopsis, a hermaphrodite that is able to reproduce independently, has declined a bit in the Black Sea.
• Self-fertilization is somewhat rare and is known only to appear in the genus " Mnemiopsis ".
• Tracing the boom back down the food chain, scientists have revealed an undersea battle whose bad guy is a comb jelly called Mnemiopsis leidyi.
• One newcomer _ the jellyfish-like Mnemiopsis leidyi _ is an " eating machine " that devours staggering amounts of the tiny plankton needed by young fish.
• Beroe, a native of the Atlantic, " probably entered the Black Sea through ships'ballast water " like Mnemiopsis a decade earlier, Ozturk said.
• One ctenophore, " Mnemiopsis ", has accidentally been Beroe " helped to mitigate the problem, as " Beroe " preys on other ctenophores.
• Self-fertilization has occasionally been seen in species of the genus " Mnemiopsis ", and it is thought that most of the hermaphroditic species are self-fertile.
• The genome of " Mnemiopsis leidyi " appears to lack recognizable microRNAs, as well as the nuclear proteins Drosha and Pasha, which are critical to canonical microRNA biogenesis.
• The tale of mnemiopsis _ pronounced ne-me-op-sis _ reflects the devastation that a single alien species can cause in an almost closed ecosystem like the Black Sea.
• The decline in macrophytes was further compounded by overfishing during the 1970s, while the invasive ctenophore " Mnemiopsis " reduced the biomass of copepods and other zooplankton in the late 1980s.
• These genes are co-expressed with opsin genes in the developing photocytes of " Mnemiopsis leidyi ", raising the possibility that light production and light detection may be working together in these animals.
• Focusing on the animals, the genome of " Mnemiopsis leidyi " appears to lack recognizable microRNAs, as well as the nuclear proteins Drosha and Pasha, which are critical to canonical microRNA biogenesis.
• "Mnemiopsis " is a carnivore that consumes zooplankton including crustaceans, other comb jellies, and eggs and larvae of fish; it is sometimes known to eat smaller individuals of its own kind.
• The comb jelly " Mnemiopsis leidyi " is an invasive species originally native to the western Atlantic coastal waters that was introduced into the Black Sea in the 1980s, with deleterious results to the ecosystem.
• Scientists believe that the jellyfish, an Atlantic native named Mnemiopsis leidyi, hitched a ride on the bottom of a ship and then rapidly multiplied, feeding on anchovy eggs and the plankton that young fish rely on.
• Anchovy populations in the Mediterranean were severely depleted in the 1980s by the invasive comb jelly " Mnemiopsis leidyi " which eats the eggs and young, they have since stabilized albeit at a much lower level.
• "What is certain, though, is that mnemiopsis altered the Black Sea as perhaps no other alien species ever had anywhere, " said Richard Harbison, a biologist at the Woods Hole Oceanographic Institute in Massachusetts.
