Radiata

To make this discovery, Blain and her team ventured out into the Hauraki Gulf to study seven kelp forests, which are mostly composed of Ecklonia radiata.

The subspecies called radiata, with flashy, bright-white leaf undersides, is another favorite of Mr. Hinkley and Mr. Wheeler.

In urban areas, where systematic spraying is problematic, University of California scientists began in 2011 to release a natural enemy of the psyllid from Pakistan, a parasitic wasp named Tamarixia radiata, which has significantly reduced but not eliminated psyllid populations.

The Madagascan radiated tortoise, Astrochelys radiata, was one of two reported missing from the zoo in 2011.

The groups complain that the logging industry's introduction of water-hungry radiata pine and eucalyptus trees since the 1980s has damaged the ecosystem.
