From Story by Danielle Hall from Smithsonian Ocean Under the lens of a microscope—in a shallow, glass well—spindly orbs pulse at regular intervals. They are, in fact, heart cells from a mahi-mahi fish, specially prepared with the precision and care required of a surgeon. A quick succession of shocks administered by fish scientist … Continued
We are extremely proud and happy to introduce you to Dr. Jason Magnuson! It has been an honor to work with him and be a part of his Ph.D journey through RECOVER at the University of North Texas. We are excited to see what the future holds for him as he continues on into his … Continued
Over the course of the past two months, we have released two videos – Mini Mahi Tags Part 1 and Tunnels and Tags: Mini Mahi Tags Part 2. These two videos are part of our three part video series featuring one of the innovative research projects being conducted by RECOVER team member, CJ McGuigan. At … Continued
Dr. Aaron Roberts, a co – principal investigator with the RECOVER consortium and based out of the University of North Texas, brought larval fish and oil spill science into the classroom at Newton Rayzor Elementary. During this 2 – week outreach program, Dr. Roberts went into the first grade classroom of Mrs. McGary and aided … Continued
Story by Maggie Dannreuther Laboratory studies at the University of Miami suggest that exposure to Deepwater Horizon oil may have negatively affected heart function in mahi-mahi, reducing their ability to swim efficiently. Lela Schlenker is expanding that research to investigate if and how oil exposure alters the way mahi-mahi migrate and respond to predators and … Continued
Last month, we released Mini Mahi Tags Part 1. This video featured the different methods being used to assess the metabolic cost and behavioral changes in captive mahi that are carrying pop – up satellite archival tags (PSATs). Wildlife Computers, developer of our PSAT tags, designed a scaled down, non – data collecting “mini” tags … Continued
Story by Maggie Dannreuther Researchers conducted exposure experiments with mahi-mahi embryos using oil, ultraviolet (UV) radiation, and temperature to determine how multiple stressors affect their survival. Compared to controls, exposed embryos floating near the ocean’s surface started to sink sooner and at faster rates, which intensified at higher temperatures. The embryos also exhibited higher oxygen … Continued
This past April, Dr. Rachael Heuer, a postdoctoral researcher with the RECOVER consortium, went back to her teaching roots and visited Easy Bay High School in Gibsonton, Florida. Dr. Heuer taught Biology, Ecology, and Advanced Placement Environmental Science at the school from 2007 – 2010, prior to beginning her graduate degree with the Grosell Lab … Continued
On April 19th, RECOVER collaborated with fellow Gulf of Mexico Research Initiative consortium CARTHE to present a screening of their documentary Dispatches from the Gulf 2. This is the second installment in their documentary series that follows the research, recovery and restorative practices within the Gulf of Mexico in the years after the 2010 Deepwater … Continued
Over the course of the next three months, RECOVER will begin preparing for our 15 day research cruise in the Gulf of Mexico, where we will continue to use PSATs (popup satellite archival tags) on wild mahi – mahi. As in the past, this will allow us to continue recording more data on mahi location, … Continued
