Given the strong relationships between rodents and ecosystems, it is important to investigate rodents’ spatial ecology. Their home range carateristics in the eastern Italian Alps still lacking compared to other alpine areas in Europe Spring Capture-Mark-Recapture using live traps + colored ear tagsWHAT ARE THE DRIVERS THAT AFFECT THE HOME RANGE SIZE? Explanatory variables were addedNDVI35METHODS WHAT IS THE INDIVIDUAL HOME RANGE SIZE? RESULTSACKNOWLEDGEMENTSA total of 4028 fixes were collected during 46 scan sessions. Individual home range varied from 0.88 to 4.74 ha for males and from 0.44 to 4.59 ha for females (median 1.97 and 1.04, respectively). The mean home range area of an average individual is 1.88 ha (CI: 1.36-2.51) (panel A). As the number of individuals per family group increased, the estimated home range size also increased (panel B).FUTURE DIRECTION: Disentangle the contribution of both environmental variables (i.e., forage quality) and human activity, which are able to shape the alpine marmot home range size.2The study was carried out in the Paneveggio-Pale di San Martino Natural Park (Italy)By drone flights, we got a raster map with a pixel size of 2.5 cm 41Each family group was scanned every 5 minutes with spotting scopes Individual home ranges were calculated by pHREML [1] of continuous-time movement (package ctmm [2]) at 95% coverage level HabitatBACKGROUNDDo you want to take a look at the maps?
