Abstract:Wildlife crossing structures are commonly used to mitigate the barrier and mortality impacts of roads onwildlife. For arboreal mammals, canopy bridges, glider poles and vegetated medians are used to providesafe passage across roads. However, the effectiveness of these measures is unknown. We investigate theeffect of canopy bridges, glider poles and vegetated medians on squirrel glider movement across a freewayin south-east Australia. We monitored structures directly using motion-triggered cameras and passiveintegrated transponder (PIT) scanners. Further, post-mitigation radio-tracking was compared to apre-mitigation study. Squirrel gliders used all structure types to cross the freeway, while the unmitigated freeway remained a barrier to movement. However, movement was not restored to the levels observed atnon-freeway sites. Nevertheless, based on the number and frequency of individuals crossing, mitigationis likely to provide some level of functional connectivity. The rate of crossing increased over several yearsas animals habituated to the structure. We also found that crossing rate can be a misleading indicator of effectiveness if the number of individuals crossing is not identified. Therefore, studies should employlong-term monitoring and identify individuals crossing if inferences about population connectivity areto be made from movement data alone.

  • An RFID-based Tracking System for Laboratory Mice in a Semi Natural Environment. Mareike Kritzler, Lars Lewejohann, Antonio Krüger,Martin Raubal, Norbert Sachser.

Abstract: Knowing the locations and paths of individual mice is important forbehavioural analysis of large groups of laboratory mice. Traditionalobservations are carried out by trained humans who are able to distinguish morethan 50 behavioural patterns. A tedious labour limited with respect to observation length. In this paper an RFID (Radio Frequency Identification)-based tracking solution is presented collecting 24h/7days of movement data. Appropriate cage design and   antenna placement are discussed and a softwaresolution is presented to facilitate the recording and analysis of mice movements.
