A race against time

River Redhorse
• Suckerfish of the Catostomidae family
• Late spawner that spawns in the middle of April
• facilitates the transfer of matter and energy from the benthic food web to the pelagic food web
• Species of greatest conservation need in the state of Florida
• Found only in the Escambia River in Florida
• Collected from the Escambia River only 3 times in the past 60 years
• Inflexible in habitat requirements and intolerant of pollution and heavy siltation
• The Escambia River has long been polluted by industrial plants. landfills, and septic tanks 
Environmental DNA
• Alternate approach to conventional methods of sampling
• Cost and time effective
• Less destructive to habitats
• Detects presence of aquatic species
• consists of sloughed-off skin cells, intestinal cells, scales, and/or mucus extracted from collected water samples
• Rapid degradation time of eDNA makes the tool useful for conservation purposes
