Novel 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 کاملConnectivity 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 کاملPhysiological Responses of Ecklonia Radiata (laminariales) to a Latitudinal Gradient in Ocean Temperature(1).
We tested the ability of sporophytes of a small kelp, Ecklonia radiata (C. Agardh) J. Agardh, to adjust their photosynthesis, respiration, and cellular processes to increasingly warm ocean climates along a latitudinal gradient in ocean temperature (∼4°C). Tissue concentrations of pigment and nutrients decreased with increasing ocean temperature. Concurrently, a number of gradual changes in the ...
متن کاملVirus - like particles associated with dieback symptoms in the brown alga Ecklonia radiata
Since 1991 epidemic dieback of the kelp Ecklonia radiata has been observed at the Leigh h4arine Reserve and other sites in northern New Zealand. As the dominant phaeophycean E. radiata is a very important component of the eastern coastal ecosystem, providing both food and refuge for many species. Examination of the E. radiata sap extracts by electron microscopy detected the presence of both str...
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...
