Kelp forests are also some of the world's largest carbon sinks, and the Great Southern Reef therefore acts as a buffer against climate change. [7] Unfortunately, an estimated 95% of the giant kelp forests off the coast of Tasmania have died off over the past few decades due higher water temperatures and the long-spined sea urchin .
[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 ...
In Alaskan kelp forest ecosystems, sea otters are the keystone species that mediates this trophic cascade. In Southern California, kelp forests persist without sea otters and the control of herbivorous urchins is instead mediated by a suite of predators including lobsters and large fishes, such as the California sheephead.
Third Eye Blind’s singer, Stephan Jenkins, spoke to SPIN about environmental conservation, reducing plastic waste, and, most particularly, about the importance of reforesting California’s ...
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.
Kelp have had to adapt dispersal methods that can make successful use of ocean currents. Buoyancy of certain kelp structures allows for species to disperse with the flow of water. [21] Certain kelp form kelp rafts, which can travel great distances away from the source population and colonize other areas.
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 groom disagreed with his wife, countering that his friend was "just joking." "But I don’t find anything funny about that," the bride insisted.
