Article 1- Investigating the viability of photo-identification as an objective tool to study endangered sea turtle populations
1. The question that the researchers are trying to answer is whether photo-identification is a sensible practice to research endangered sea turtles. Their hypothesis was that people would be able to accurately, reliably, easily be able to distinguish individual sea turtles using natural markings. The researchers’ prediction is that if people use photo-identification then they will be able to determine individual sea turtles by matching the markings in the picture to the sea turtle.
2. For the experiment, first, an expert observer is tested on her matching abilities of the photos to tagged turtles with and

Article 1- Investigating the viability of photo-identification as an objective tool to study endangered sea turtle populations
1. The question that the researchers are trying to answer is whether photo-identification is a sensible practice to research endangered sea turtles. Their hypothesis was that people would be able to accurately, reliably, easily be able to distinguish individual sea turtles using natural markings. The researchers’ prediction is that if people use photo-identification then they will be able to determine individual sea turtles by matching the markings in the picture to the sea turtle.
2. For the experiment, first, an expert observer is tested on her matching abilities of the photos to tagged turtles with and without an identification tree. Then naïve observers were asked to separate the turtles into groups (trial 1) and from the groups, matching the turtles to the photos (trial 2). The responding variable is how accurately and fast the naïve observers can identify the sea turtles using photo-identification. The control variables are that all the turtles are loggerhead sea turtles coming from Laganas Bay, Zakynthos island, Greece, all photo-identification pictures were taking using an Olympus Digital 500 (5.0 megapixel) camera, and the pictures were taking while snorkeling between 2-7 meters from the turtles from April up to August. The manipulated variable is the person photo-identifying the turtles and is either an expert or a naïve observer in
