Enzymatic activity is at the core of biological reactions. Understanding them and the chemical and environmental factors that affect reaction rates is critical for biology students. The laboratory experiment proposed here investigated these concepts, while requiring students to document, graph data, analyse results using statistics, and…

More than 90% of vascular plants in terrestrial ecosystems form symbiotic root-fungal associations known as mycorrhiza; in Mediterranean biomes all known mycorrhizal types co-exist. However, the understanding of mycorrhizal diversity and structure and their ecophysiological impact in soil productivity and conservation has been shown to be very…
