    Description: The Kemp's ridley turtle (Lepidochelys kempii) is an endangered species whose recovery depends in part onthe identification and protection of required habitats. We used radio and sonic telemetry on subadult Kemp's ridleyturtles to investigate home-range size and habitat use in the coastal waters of west-central Florida from 1994 to1996. We tracked 9 turtles during May-August up to 70 days after release and fou.ld they occupied 5-30 km2 foragingranges. Compositional analyses indicated that turtles used rock outcroppings in their foraging ranges at asignificantly higher proportion than expected. based on availability within the study area. Additionally. turtles usedlive bottom (e.g .• sessile invertebrates) and green macroalgae habitats significantly more than seagrass habitat. Similarstudies are needed through'mt the Kemp's ridley turtles' range to investigate regional and stage-specific differencesin habitat use. which can then be used to conserve important foraging areas.

    Description: Radio and sonic telemetry were used to investigatethe tidal orientation, rate of movement(ROM), and surfacing behavior of nine Kemp's ridleyturtles, Lepidochelys kempii, tracked east of the CedarKeys, Florida. The mean of mean turtle bearings onincoming (48 ± 49 0) and falling (232 ± 41 0) tides wassignificantly oriented to the mean directions of tidal flow(37±9°, P〈0.0025, and 234±9 0, P〈0.005, respectively).Turtles had a mean ROM of 0.44±0.33 km/h(range: 0.004-1.758 km/h), a mean surface duration of18± 15 s (range: 1-88 s), and a mean submergence durationof 8.4± 6.4 min (range: 0.2-60.0 min). ROM wasnegatively correlated with surface and submergencedurations and positively correlated with the number ofsurfacings. Furthermore, ROMs were higher and surface and submergence durations were shorter during the day.Daily activities of turtles were attributed to food acquisitionand bioenergetics.
