  • Dataset Abstract
    American alligators (Alligator mississippiensis) are top predators in the Florida Coastal Everglades (FCE), but their movement patterns and role in the ecosystem are largely unknown. Proposed restoration and management efforts in the Everglades are likely to influence both alligator movements and the spatiotemporal patterns of their effects on ecosystem and community dynamics, making studies of the factors influencing alligator movements important at this time. In October 2007, we initiated a study of alligators in the Shark River Slough of Everglades National Park using two tracking techniques that have yet to be used on crocodilians: GPS tracking and passive acoustic telemetry. GPS units attached to two alligators have provided 120 positions over a two month period while acoustic transmitters attached to 12 alligators have been detected 34,000 times on an array of 8 monitoring stations within the river system. GPS positions are more accurate than acoustic monitoring and can provide data over the entire range an alligator might move, but acoustic transmitters provide more temporally detailed information on movements within a monitoring array and over a longer duration (potentially years rather than months). Our preliminary results show that alligators may remain in localized areas for weeks at a time, but make long-distance moves from the mouth of the river system to the marsh-mangrove ecotone and likely into the marsh. In general, most alligators moved upstream as freshwater inputs decreased, but some individuals remained near the river mouth even when salinities were high. Ultimately, by characterizing alligator movements in relation to spatiotemporal variation in environmental factors we will be able to predict how alligator distributions and populations will respond to planned increases in freshwater flow. Furthermore, movement data combined with dietary and stable isotopic studies may shed light on the possible role of alligators in the redistribution of nutrients throughout the Shark River system.

  • Methods
    Sampling Description
    Temperature data was collected by 8 HOBO Water Temp Pro v2 temperature loggers (one at each site) positioned approximately 10cm above the river bottom. Six of the loggers recorded the temperature every 10min and 2 of the loggers recorded the temperature every 15min.

    Method Step

    Description
    Temperature data was collected by 8 HOBO Water Temp Pro v2 temperature loggers (one at each site) positioned approximately 10cm above the river bottom. Six of the loggers recorded the temperature every 10min and 2 of the loggers recorded the temperature every 15min.

    Instrumentation
    HOBO Water Temp Pro v2 (Onset, Bourne, MA)

    Quality Control
    Quality control consisted of checking the temperature readings at each station with a YSI probe at least once every 2-6 weeks and then comparing the YSI readings to the HOBO logger readings.
