- <em>I</em><u><em>t was important that Mendel examined not just the F1 generation in his breeding experiments, but the F2 generation as well, because parental traits that were not observed in the F1 reappeared in the F2.</em></u>
<h2>ecosystem services provided by biodiversity, such as nutrient cycling, carbon sequestration, pest regulation and pollination, sustain agricultural productivity. Climate change and other stresses have the potential to make major impacts on key functions, such as pollination and pest regulation services.</h2><h2 />
