How do biotic and abiotic factors combine to affect the weathering of wood surfaces

The paper presents the aim and objectives of a research project concerned with the weathering processes of oak (Quercus robur.) and Douglas fir (Pseudotsuga menziesii). The project deals with the identification of any synergistic effects between biotic factors such as aerobic bacteria, Basidiomycota, Ascomycota and abiotic factors such as light, temperature and moisture on the weathering of wood surfaces in durability class 3.
