| summary | In the 1940’s, Pers Scholander had the idea of attaching acapillary depth gauge on a freshly-harpooned whale to examine thediving ability of the cetacean. This is often regarded as the onset ofwhat was going to be termed bio-logging 6 decades later. Indeed, fromthe simple tube filled up with a sugary solution of Scholander to the14-channels, high frequency sampling unit designed by Rory Wilson,bio-logging has grown up to be a must-have tool for scientists willingto track and monitor their subject models moving freely in theirenvironment. Although a handful of companies share the majority of themarket, several manufacturers are now available. This contributed todecrease the cost of bio-loggers while stimulating the technicaldevelopments. Thanks to this, the number of species investigated hasincreased tremendously as miniaturization progresses and allowedresearchers to instrument increasingly smaller species. Followingadvances in miniaturization, devices have also grown in complexity,accommodating diversified sensors that have expanded the range ofscientific disciplines concerned with bio-logging approach. Thedifficulty to retrieve the logger to access the data has recentlypushed bio-logging developers to explore the duality of storing datain the memory of the devices before sending them at appropriate times,either via radio or via satellite, to fixed stations where they can beretrieved, hence combining telemetry and bio-logging into a singleapproach. During this talk I will present an historical account of theuse of bio-logging in ecological, ethological, physiological andecosystemic studies. |
