ABSTRACT The physiological and behavioral ecology of the terrestrial amphipod Arcitalitrus sylvaticus (Haswell, 1880) was investigated. Four main aspects were examined: thermal tolerance and thermal acclimation, water loss, resistance to desiccation (as survival), and orientation along a humidity gradient. Thermal tolerance was not affected by the body weight of the amphipod but could be altered through acclimation to higher temperatures. Transpiration rates were affected by body weight, i.e., small amphipods lost water faster than larger amphipods. In dry air (20% relative humidity) and moist air (100% relative humidity) transpiration rates were directly affected by temperature. The survival of A. sylvaticus was tested at various temperature-humidity combinations; survival for periods longer than 48 h was achieved only at relative humidities of 100% at temperatures less than 30°C. In an experimental chamber designed to maintain an internal gradient of 50-100% relative humidity, a higher frequency of position records was recorded on the more humid side. In contrast, amphipods placed inside a chamber with a uniform relative humidity of 100% showed no preference to chamber side. The results provide evidence that A. sylvaticus adapts to the terrestrial habitat through behavioral rather than physiological mechanisms.
