This publication describes some of the ways to measure ecosystem services and explains how the different approaches to assess ecosystems might be selected, depending on what is most important to the user.

Soils have the capacity to function as a sink of atmospheric carbon dioxide and are crucial for climate regulation. Soil have the potential to store around 1.5 to 2.4 trillion metric tons of C in the soil globally. They contain large C pools that can store three times more C than the atmosphere and four times more than plants. These massive C sinks have the potential to reverse soil degradation, mitigate climate change, and enhance food security. It is therefore essential to monitor the C cycle by accurately measuring the amount of soil C in agricultural fields. This can help in developing sustainable management practices that can minimize C emissions and sequester C into the soil from the atmosphere. This publication describes the various current and emerging protocols that can be used to measure soil C.

The goal of this study was to develop a rapid assessment of microalgal concentration using a turbidity meter to serve commercial shellfish hatcheries for feeding shellfish larvae and broodstock. We used four commonly used algal species, Tetraselmis suecica, Isochrysis galbana, Chaetoceros calcitrans, and Chaetoceros gracilis, generating serial dilutions of each and measuring cell concentrations and turbidity of each sample. We identified linear correlations between cell concentration and turbidity and established standard equations between cell concentration and turbidity for each species. We sampled and quantified algae from a shellfish hatchery using these equations and compared hemocytometer counts. No differences were found (P = 0.174), indicating the accuracy of the equations. We expect that this method can provide a quick, accurate, easy method for shellfish hatcheries to quantify algal concentration and avoid either over- or underfeeding larvae and broodstock.
