Abstract: A system for preserving or establishing an ecosystem comprises an assembly coupled to a guidance component. An assembly comprises an enclosure and a substrate, and is configured to contain one or more organisms within the enclosure. The guidance component causes the assembly to be transported to a destination environment. The assembly is decoupled from the guidance component. The assembly detaches from the substrate, to integrate the one or more organisms into an ecosystem of the destination environment.

Abstract: A storage unit for CD discs comprises a box-like housing in which is mounted a vertical spaced array of horizontally disposed sleds. The sleds slide in and out of the housing on tracks provided in the housing sidewalls. Conventional CD jewel boxes are retained on the sleds and a rod engaging the underside of the lid of each jewel box passes through the jewel box with its ends engaged in a groove formed in the side walls of the unit. The grooves are configured to move the rod vertically away from the sled as the sled is moved out from the housing. The vertical movement of the rod forces the lid of the CD up, giving the user access to the CD stored in the jewel box.
