Upwelling
The major upwellings in the ocean are associated with the divergence of currents that bring deeper, colder, nutrient rich waters to the surface. There are at least five types of upwelling: coastal upwelling, large-scale wind-driven upwelling in the ocean interior, upwelling associated with eddies, topographically-associated upwelling, and broad-diffusive upwelling in the ocean interior.
Geocrinia rosea
The frog is restricted to the higher rainfall region in around the Karri forest at the southwest tip of the continent. Streams flow into and by the Warren river, and the permanent moisture found there is the haven and restraint. The high rate of endemism in the result of the lack of motility in the species. But spring and summer bring drive to form amplexus, and the poorly travelled males will cry for a mate with four beats of the generic 'tk'. Here the frog remains amongst the depressions and recesses, the female leaving its eggs amidst the fallen timber and dense vegetation of the lush Warren region. The young will emerge from the degrading gelatinous spawn as complete froglets, never swimming in more than the damp floor of their abode.
