Complex marine forests collapsing into flat turf seascapes
An international study led by The University of Western Australia has found that temperate marine ecosystems dominated by marine forests are collapsing into flattened seascapes of short turf algae across the globe.
The study, published in Global Change Biology, reveals that in Western Australia alone, thousands of hectares of underwater forests have collapsed into short carpets of seaweed turf.
Some of the other worst affected areas globally include southern Norway, eastern North America, the Mediterranean Sea and southern parts of Japan.
Lead author Albert Pessarrodona, from the UWA Oceans Institute and School of Biological Sciences, said marine forests were formed fromed by large seaweeds that towered up above the ocean floor, forming underwater canopies that house many species of fish, invertebates and algae.

Scientists harness naturally abundant CRISPR-Cas system to edit superbugs
An illustration of the strategies and workflow of the transferrable type I CRISPR Cascade-mediated editing of the superbug P. aeruginosa.
A research team led by Dr Aixin YAN, Associate Professor from the Research Division for Molecular & Cell Biology, Faculty of Science, in collaboration with Honorary Clinical Professor Patrick CY WOO from the Department of Microbiology, Li Ka Shing Faculty of Medicine, the University of Hong Kong (HKU), reported the development of a transferrable and integrative type I CRISPR-based platform that can efficiently edit the diverse clinical isolates of Pseudomonas aeruginosa, a superbug capable of infecting various tissues and organs and a major source of nosocomial infections. The technique can accelerate the identification of resistance determinants of multidrug resistant (MDR) pathogens and the development of novel anti-resistance strategies.
