In Australia, cultured greenlip abalone ( Haliotis laevigata ) are fed formulated diets that lack macroalgae. This has resulted in a pale lip colour in contrast to the vivid green lip colour of wild abalone. We evaluated the effects of supplementing 15% dried macroalgae meal, using either commercially available macroalgae meal (MSM) or harvested Gracilaria cliftonii, on colour change in greenlip abalone . Abalone were fed the...

However, the rates of non‐native spread in new regions and their determinants have not been comprehensively studied. Here, we combined global databases documenting the occurrence of non‐native species and residence of non‐native birds, mammals, and vascular plants at regional and local scales to describe how the likelihood of non‐...
