Note that only some of CoralNet's labels have rates provided, and many of those labels only have rates provided in one region.
You can view all the rates CoralNet provides in CSV format here:
Rates are in units of kg CaCO3 m-2 yr-1. A rate above 0 means that the label's presence contributes to positive carbonate production (i.e., calcification). A rate below 0 means that the label's presence contributes to negative carbonate production (i.e., bioerosion).
CoralNet's calcification rates are derived from ReefBudget's data.
Gracilaria coronopifolia has solid, cylindrical branches, 1 - 2 mm in diameter, with short pointed tips. The plant may arise from one to several branches that undergo frequent branching, with each subsequent branching shorter, but not thinner, than the previous. The upper plant becomes more densely branching and forms a small bush, to 15 cm tall, with a rounded profile arising from a discoid holdfast. The plant is often red, but may bleach to pink or white in bright sunlight.
