Abiotic Conditions in a Habitat Beneath a Rock using Light and Temperature Sensors

Figure 1

Introduction Turning over a rock reveals a world teeming with life, consisting of organisms from different classes and families such as worms, arthropods, etc. The rock isolates the area it covers from the surroundings, thus creating relatively stable abiotic conditions. Three main abiotic parameters affect all living organisms: temperature, humidity and light. The intensity of light radiation varies daily and annually with solar radiation. Radiation striking the rock and winds blowing in the area are the main sources for temperature and humidity fluctuations in the rock and its surroundings. In this experiment we use sensors to perform field measurements comparing temperature and light conditions found below and on the surface of a rock.
