Description:

Abstract:

In 2001 a mark-recapture study on mangrove terrapins (Malaclemys terrapin) in the Big Sable Creek (BSC) complex within Everglades National Park was initiated. The summary data for terrapins in BSC were collected over 5 sampling trips in a two-year period (November 2001 - October 2003) and from analysis of individual terrapin capture histories.

Purpose:

Study objectives were to estimate adult survival probablility, capture probablilty, and abundance of terrapins at this study site. This allowed the establishment of the first baseline assessment for mangrove terrapins in the coastal Everglades.

Taxonomic_Procedures:

We worked throughout navigable, mangrove-lined tidal creeks within the BSC complex and conducted all sampling trips around new moons to take advantage of spring tides (i.e., highest high and lowest low tides). Dip netting was most successful during a 2-hour window around both day and evening low tides.

Methodology:

Methodology_Type: Field

Methodology_Description:

Mark-recapture techniques were used for Diamondback terrapins. Three weeklong sampling trips were made to the Big Sable Creek system to capture, mark, and recapture terrapins. Captures were concentrated in the upper reaches of creeks in the system. On each sampling trip, named creeks and their navigable branches were surveyed systematically for terrapins at AM and PM low tides. Dip nets were used to capture turtles, with the new moon tides providing the best conditions for capture success.

Methodology:

Methodology_Type: Field

Methodology_Description:

In addition to taking standard morphometric measurements on each turtle and recording a GPS location for each capture and recapture location, we marked each newly captured terrapin in four ways: (1) by notching the marginal scutes in a systematic pattern, (2) by inserting an individually numbered 9-or 10-digit alpha-numeric passively induced transponder (PIT) tag, (3) by taking head-on, dorsal, ventral, and side view photographs for photo-id (with particular emphasis on capturing the unique pattern of each turtle’s plastron), and (4) by taking blood samples to be screened for microsatellite DNA markers which resulted in locus-specific scores for each individual. For consistency, K. Hart performed all the notching, PIT tagging, photographing, and blood sampling throughout the study. We used the redundant marking system to ensure no tag loss or errors in identification. We also used strict, consistent protocols to catalog animals so that the possibility of misidentification would be essentially zero. We re-weighed and re-measured recaptured turtles, and released all new turtles after workup at their original capture site and all recaptured turtles at their recapture location. Additionally, we attached radiotransmitters to a subset of females to conduct short-term tracking in the study site. For analyses, we constructed a unique 5-capture history for each of the 300 terrapins from the capture and recapture data collected on each trip. Each capture history consisted of the seen (1) or not seen (0) record of the individual during each of the five sampling periods.

We marked a total of 300 terrapins. We captured 24 animals in crab pots on the first sampling trip (November 2001), but thereafter captured terrapins only with dip nets.

Methodology:

Methodology_Type: Lab

Methodology_Description:

We used Program MARK and AIC model selection procedures to derive estimates of survival and capture probability. We used JOLLY Model B to estimate population size.

Process_Step:

Process_Description:

Significant progress has been made on quantitatively establishing baseline patterns of the distribution and abundance of diamondback terrapins in the Big Sable Creek complex.

Process_Date: 2001

Process_Step:

Process_Description:

Terrapin sampling using dip nets in the Big Sable Creek complex was initiated in November 2001. Samples were also taken in July 2002 and December 2002. Over 250 animals are marked, 10 females have been radio-tagged and samples have been collected for genetic analysis.

Process_Date: 2003

Process_Step:

Process_Description:

Work completed in FY 2004 included:

We continued to define population structure and genetics of Diamondback terrapins at Big Sable Creek complex immediately south of Shark River. A total of 300 unique individuals with a male: female sex ratio of 1.2:1.0 have been captured, measured, weighed, PIT tagged and had blood drawn for genetic samples. Initial population size estimate is about 1,415 individuals based on the Schnabel method. We estimated downed log cover in 6 headwater creeks to correlate with terrapin capture locations. Final objectives are to refine this population estimate, better characterize habitat use, and finish analysis of blood samples previously collected for DNA characterization.

Process_Date: 2004

Process_Step:

Process_Description:

Ongoing work:

Future analysis of mark-recapture data will allow for determination of effects of hurricanes (i. E., Hurricane Wilma, October 24, 2005) on terrapin survival and capture probabilities.

Genetic analysis is continuing for this population to determine hurricane effects on allele frequencies over time.
