eDNA Source Tracking Toolkit Workshop - April 25, 2025
|
|
The eDNA Source Tracking Toolkit is a resource for utilizing eDNA metagenomics as a fecal source tracking tool. The Toolkit workshop was hosted on April 25, 2025 at the University of South Alabama to guide stakeholders and community partners in implementing next generation source tracking techniques. For more information on the toolkit, please visit the eDNA source tracking toolkit website via the "eDNA Toolkit" tab. This toolkit and workshop are funded by Environmental Protection Agency Gulf of Mexico Division grant MX-02D17922. More information on this research project can be found under the "Research" tab. |

|
Come aboard the R/V Pelican (virtually) for a peek into the scientific sampling of the northern Gulf of Mexico for the September 2024 QUALIFIED research cruise. More information on the QUALIFIED project can be found on the "Research" page under Microbial Sediment Diagenesis. |
DISL Seminar: Penny Demetriades and Lydia Hayes-Guastella research presentations
|
|
Kiel Reese PhD students Penny and Lydia present for Dauphin Island Sea Lab (DISL) seminar on September 6, 2024. Penny Demetriades presents her research "Molecular-based Investigations of Microbial Source Tracking within Mobile Bay" and Lydia Hayes-Guastella presents her research "Microbial Carbon Cycling in Energy-Limited Subsurface Environments." |
Boardwalk Talk: Marine Deep Subsurface Fungi and How We Find Them
|
|
Little is known about fungi in sediments deep below the seafloor because accessing the marine deep subsurface is expensive and difficult. Fungi have the unique ability to break down carbon sources that other organisms cannot, making them an important part of the carbon cycle and in interactions with other microorganisms. Lydia Hayes-Guastella talks about how deep sea fungi can survive in the deep subsurface, how they are sampled, and what scientists are learning about their ecological roles. |

Podcast: Absolute Gene-ius S1, E6: PCR on 'zombie' organisms in extreme environments
|
|
Absolute Gene-ius Podcast welcomes Dr. Brandi Kiel Reese and Lydia Hayes-Guastella from the Dauphin Island Sea Lab at the University of South Alabama to talk about using digital PCR and other methods to study microbial life and survivability in extreme environments. They tell us all about their work collecting and analyzing samples from places as remote as Antarctica and the Mariana Trench. They share what working in such unique locations is like, how samples are collected and analyzed, and what they hope to glean from their studies. |

Boardwalk Talk: International Ocean Discovery Program
|
|
Little is known about deep-sea microbes and the life strategies that enable them to survive in extreme environments. Geomicrobiologist Dr. Brandi Kiel Reese discusses how scientists sample these extreme organisms (through drilling vessels and programs such as the International Ocean Discovery Program), what has been discovered about deep sea microbes, and all that is still left to learn. |
