The Great Southern Reef is named after its world-famous neighbour to the north, the Great Barrier Reef, but has received a fraction of the attention and protection given to the latter. The Great Southern Reef is an important biodiversity hotspot and annually contributes more than AU$10 billion to the Australian economy. [2]
[3] [4] In Australia, E. radiata forms the backbone of the Great Southern Reef, a system of interconnected kelp reefs that spans the coastline of southern Australia, underpinning biodiverse and productive ecosystems, and supporting valuable ecosystem services. [5] Ecklonia radiata grows in kelp beds on reefs and where sheltered can form dense ...
The rest of New Zealand's subantarctic islands are part of the Southern Ocean realm. [ 1 ] In large parts of the realm along the southern coast of continental Australia, a network of rocky reefs and kelp forests has created a unique biodiversity hotspot known popularly as the Great Southern Reef .
More recent research suggests that the weedy seadragon may be far more endangered than initially assumed as a result of climate change-induced marine heatwaves on the Great Southern Reef. Edgar et al (2023) documented a population decline of 59% between 2011 and 2021, a period of frequent and extensive marine heatwaves.
The kelp floats as a raft and can travel vast distances at sea, driven by ocean currents. Kelp-associated invertebrates can be transported inside of drifting holdfasts, potentially leading to long-distance dispersal and a significant impact upon the population genetic structure of those species. [26] [27] [28] [29]
Kelp forests are a variation of rocky reefs, as the kelp requires a fairly strong and stable substrate which can withstand the loads of repeated waves dragging on the kelp plants. The sea bamboo Ecklonia maxima grows in water which is shallow enough to allow it to reach to the surface with its gas-filled stipes, so that the fronds form a dense ...
The Troubled-Teen Industry Has Been A Disaster For Decades. It's Still Not Fixed.
The Blue Hole is popular with divers and swimmers. The Blue Hole of Santa Rosa, or simply the Blue Hole, is a circular, bell-shaped pool or small lake located along Route 66 east of Santa Rosa, New Mexico that is a tourist attraction and swimming venue, and one of the most popular dive destinations in the US [1] for scuba diving and training.
