As in the previous situation, beginning in the en garde position, the fencers lunged as swiftly as possible trying to place the sword point inside the circle that appeared within the plastron
The fixed-effect explanatory variables were the individual-specific variables sex and plastron
length, plus the following day-specific variables: solar irradiance, minimum daily temperature, maximum daily temperature, total evaporation, average wind speed, and day (June 7 = Day 1, to account for any consistent trend in detection probability).
Se coloco el individuo en decubito dorsal para obtener acceso a las visceras internas por el corte o aserrado alrededor de los bordes del plastron

3 mm straight plastron

It had a fully developed plastron

Three adult turtles, tagged for identification using colored pipe cleaners wrapped around the carapace and plastron
