Questions (4)
We are launching a Ph.D. research looking at the effect of salinity and temperate increase on the bioerosion rates in coral reefs in the northern Persian Gulf. In doing so, artificial and natural blocks will be submerged along a gradient of salinity and temperature where hypersaline water from the desalination plant discharges into the sea. We are planning to use two types of natural and artificial blocks including (1) natural blocks by segmenting dead massive corals (e.g., Platygyra sp.); and (2) artificial blocks made of carbonate calcium.
But wonder how to make artificial blocks that need to be identical to natural blocks in terms of porosity and texture. Can we use crushed dead corals that have been blocked by a glue? If yes? What type of glue?
Wondering if anyone has experience in making such artificial blocks.
Best regards
Mohammad
I am trying to identify the subset of non-gelatinous zooplankton species that show correlation with jellyfish species. I have abundance data for
non-gelatinous zooplankton species. While the jellyfish data are presence-absence data.
I am wondering how I can run a forward selection process in Canoco 5 to do so?
Any help would be highly appreciated.
I am wondering if anyone can send me the PDF of of Primer v6: User Manual/Tutorial.
I am wondering if it is possible to perform a PERMANOVA analysis with a matrix of presences-absences using Jaccard as measured distance in Primer.
