USING RADIO TELEMETRY TO TRACK SUMMER MOVEMENTS OF COMMON MUDPUPPIES (NECTURUS MACULOSUS) IN A DISTURBED, URBAN LAKE
Common mudpuppies (Necturus maculosus) have a broad distribution across central to eastern North America. Seasonal behaviors of these fully aquatic salamanders are poorly understood, with more frequent encounters by fishermen occurring in winter than summer. The Shedd Aquarium veterinary staff implanted radio-telemetry transmitters in 20 mudpuppies captured in Wolf Lake, near Chicago, IL. Mudpuppies were located, on average, every 17.2±4.2 days from April-November. There was no difference between mean male (16.6m) and female (11.2m) movement distance throughout the tracking period (p=0.30). Seventeen out of twenty mudpuppies moved the greatest distances immediately after release, or during the two periods of highest water temperature increases. The period between late May and early June corresponded with the largest movements for male (398.1m) and female (298.6m) mudpuppies throughout the study. This overlapped with the second highest temperature increase throughout the study period (+6.5oC), an increase to 23.7oC. The underlying mechanisms that prompt summer movements and habitat selection for mudpuppies is essential for conservation efforts. With further analyses, habitat preference throughout the year will be determined to aid in conservation management and planning for this understudied and vulnerable species.
