The federally threatened eastern indigo snake (EIS; Drymarchon couperi ) is an active ophiophagous snake once found throughout the southeastern US that is now restricted to southeastern Georgia and peninsular Florida. There are concerns regarding the potential impact of overconditioning or nutrient…
- Development of an assay for the detection of the federally threatened Florida eastern indigo snake ( Drymarchon couperi ) using soil eDNA
Carlos A. Santamaria, Emily Galbraith, Alison Melissa Gainsbury · Conservation Science and Practice · 2024-10 · open access
Abstract Accurate information on species range contraction is the cornerstone of effective biodiversity conservation. The eastern indigo snake ( Drymarchon couperi ) is an apex predator in Florida and, similar to many species native to Florida, is threatened by widespread habitat destruction.…
- Evaluating the Effects of Viruses on Eastern Indigo Snakes ( Drymarchon couperi ) with Gastric Cryptosporidiosis.
Bogan JE Jr, Ossiboff RJ, Childress AL et al. · Viruses · 2024-09 · open access
A breeding colony of wild-origin eastern indigo snakes (EISs, Drymarchon couperi ) that is part of a reintroduction program has been impacted by gastric cryptosporidiosis. Gastric cryptosporidiosis is an insidious disease of squamates caused by an apicomplexan protozoan, Cryptosporidium serpentis .…
