It is important to note that these changes were synchronous between each BDDL and its respective live limpet measurement. Gradual longer lasting changes in the recorded humidity of live limpets and BDDL were indicative of precipitation Figs. 8 and the presence of solar radiation Fig. 9 both of which could be dually verified by changes in the body temperature. In fact during the field deployment at Le Croisic sw France changes in RH were inversely correlated with changes in body temperature Fig. 8 . 2 2 a CL E Time hours Fig. 9. Comparison between water loss measured in a live limpet P 97 0 t ibl line and water loss as recorded by two biomimetic desiccation loggers blue and orange lines on a supralitoral rocky surface at Lavra NW Portugal on June 23rd-24th 2010. The temperature trajectory of the limpet is shown in red. Period c corresponds to strong afternoon sun which was followed by sunset at D. Temperatures decreased gradually during the night but rose at sunrise E causing evaporative water loss in the live animal and in the biomimetic loggers. On the most basic level BDDL can measure the frequency and relative magnitude of desiccation stress associated with wind and larger meteorological events as experienced by the study organism in any possible microclimate. Wind in combination with low humidity has been suggested as a dominant physical stressor on some rocky shores Bertness et al. 2006 Bazterrica et al. 2007 . The scope of quantifiable parameters is limited in this data logger allowing several options for interpretation. A catalogue of the data loggers behaviors referenced against real meteorological events specific to any study site can easily be compiled allowing for a more accurate interpretation of data. The electronic basis of BDDL also presents an obstacle for long term and widespread field monitoring. The .
