Apium virus Y Apium virus Y "Apium virus Y" (ApVY) is a plant pathogenic virus in the genus "Potyvirus" and the virus family "Potyviridae". Apium virus Y is a recently described member of the potyvirus family. It was first found in Australia in 2002 in poison hemlock ("Conium maculatum": an immigrant weed in Australia). A survey of native and weed species in the family Apiaceae found ApVY to be widespread in Australia. In addition, this survey and others found two other potyviruses. One was a well-known potyvirus infecting the Apiaceae, "Celery mosaic virus" (CeMV). CeMV has been found in celery ("Apium graveolens") crops
Yellow-banded poison dart frog sex. Uniquely, it is also the only poison dart frog to estivate during dry spells. Yellow-banded poison dart frogs reproduce sexually. The mother lays her fertilized eggs (zygotes) in a body of water. When they hatch, they are called tadpoles. Like all Dendrobatidae, "D. leucomelas" frogs secrete toxins from their skin, which they gain from eating certain unspecified arthropod prey. It is uncertain precisely which arthropods lend their toxicity to which genus of Dendrobatidae, but one such arthropod is thought to have been identified as a possible source of the toxin for Dendrobatidae "Phyllobates terribilis" (aka the golden poison frog),
