Connectivity of the Habitat-Forming Kelp, Ecklonia radiata within and among Estuaries and Open Coast
With marine protected areas being established worldwide there is a pressing need to understand how the physical setting in which these areas are placed influences patterns of dispersal and connectivity of important marine organisms. This is particularly critical for dynamic and complex nearshore marine environments where patterns of genetic structure of organisms are often chaotic and uncoupled...
متن کاملNovel ssDNA Viruses Detected in the Virome of Bleached, Habitat-Forming Kelp Ecklonia radiata
Kelp forests provide essential habitats for organisms in temperate rocky shores. Loss of kelp forests has occurred over large areas in a number of temperate regions, including in Australia, where the dominant kelp Ecklonia radiata has been lost from substantial areas of the shoreline. Loss of E. radiata has been associated with environmental stressors, including increased temperature and anthro...
متن کاملThe extent of die-back of the kelp Ecklonia radiata in the Cape Rodney to Okakari Point Marine Reserve
The extent of die-back of the kelp Ecklonia radiata in the Cape Rodney to Okakari Point Marine Reserve. Summary The kelp Ecklonia radiata has undergone high rates of mortality in a region of northeastern New Zealand stretching from Whangarei Heads south to Cape Rodney and east to Great Barrier Island. Die-back of this kelp began in late 1991 and continued up to May 1993, with mortathy of over 9...
متن کاملAnalysis of coelom development in the sea urchin Holopneustes purpurescens yielding a deuterostome body plan.
An analysis of early coelom development in the echinoid Holopneustes purpurescens yields a deuterostome body plan that explains the disparity between the pentameral plan of echinoderms and the bilateral plans of chordates and hemichordates, the three major phyla of the monophyletic deuterostomes. The analysis shows an early separation into a medial hydrocoele and lateral coelomic mesoderm with ...
متن کاملOcean acidification reverses the positive effects of seawater pH fluctuations on growth and photosynthesis of the habitat-forming kelp, Ecklonia radiata
Ocean acidification (OA) is the reduction in seawater pH due to the absorption of human-released CO2 by the world's oceans. The average surface oceanic pH is predicted to decline by 0.4 units by 2100. However, kelp metabolically modifies seawater pH via photosynthesis and respiration in some temperate coastal systems, resulting in daily pH fluctuations of up to ±0.45 units. It is unknown how th...
