R. SH. responds differently than NPP to fertilization and drought treatments, leading to the divergent responses of NPP and NEP. Moderate responses of NPP (+11%) and R. SH. (−7%) to fertilization combined such that NEP increased nearly threefold in ambient control and 43% under drought treatment. also known as antibodies, are glycoprotein molecules produced by plasma cells (white blood cells). They act as a critical part of the immune response by specifically recognizing and binding to particular antigens, such as bacteria or viruses, and aiding in their destruction..
