Understanding Animal Residency

2022-08-24T13:24:18+00:00

What is animal residency and how do we define and measure it? In marine mammal research, residency is often used to describe the place that animals (or groups of animals) occupy in a given geographic space over a long period of time. In fact, the SDRP made the discovery that bottlenose dolphins can form

Fatty Acid Signatures

If they are what they eat, what are dolphins eating? Thanks to our long-term studies — including seasonal fish surveys — we know what the most common prey fish are in Sarasota Bay dolphin diets. But how do their diets change during events like red tides? SDRP’s Theresa Tatom-Naecker is testing a technique called

2021 Baby Boom

2021-12-09T12:55:22+00:00

The Chicago Zoological Society’s Sarasota Dolphin Research Program has documented 22 dolphin births in 2021 to the long-term resident bottlenose dolphin community of Sarasota Bay, Florida, exceeding the record of 21 set in 2017. The newest calf was first observed with its mother, known as Squarenotch, on Dec. 2. Forty-four-year-old Squarenotch

When the Prey is Gone

2021-11-10T15:19:38+00:00

When the Prey is Gone Gaining a fuller understanding of dolphins also means studying how they interact with their environment, including learning about one of the main ecological drivers for their behavior: prey availability. A new study published in the journal Frontiers in Marine Science has taken the first step in identifying how

When Dolphins and Freshwater Mix

2021-11-09T18:35:46+00:00

What Happens When Dolphins and Freshwater Mix? Prolonged exposure to freshwater is linked to adverse health conditions, immune deficiencies, and even dolphin deaths, but there’s still a lot we don’t understand. SDRP Post-doctoral Scientist Dr. Christina Toms was conducting photo identification surveys in Pensacola Bay, Florida, as part of an

Seagrass Matters

2021-10-05T15:23:08+00:00

Seagrass Matters This summer (2021), we've continued our purse-seine catch-and-release fish surveys in Sarasota Bay. These surveys, conducted seasonally since 2004, allow us to gain an indication of the relative abundance of fish in Sarasota Bay — important information for understanding one of dolphins’ main ecological drivers: their prey. Our

Taking Lessons From Sarasota Abroad

2022-01-25T16:04:55+00:00

This 2008 photo shows researchers preparing to release a tagged franciscana dolphin in Argentina. Dolphins were held for a brief period while satellite-linked tags were applied and then the dolphins were released on site. Lessons Learned in Sarasota Are Applying to Dolphin Conservation in Argentina and Brazil With research

Dolphins & Hurricane Season

2021-06-09T11:54:18+00:00

Dolphins & Hurricanes One question we’re frequently asked is what dolphins do during hurricanes. The short answer is that we just don’t know. Since it’s not safe for humans on boats to be out during storms, we have to rely on opportunistic reports for insights. A few years ago, we

What is Happening to the Dolphins Near Piney Point? We're monitoring the dolphin community near Port Manatee for impacts from the Piney Point discharges of polluted water If you’ve been following the news lately, you’ve probably heard about the discharges of phosphorous and nitrogen polluted waters from Piney Point,

Crunch! Understanding Eagle Ray Diets

2021-03-18T13:29:16+00:00

Crunch! Understanding Eagle Ray Diets For the first time, a team of researchers has demonstrated that passive acoustic recorders can be used to help identify the prey that whitespotted eagle rays (Aetobatus narinari) eat, based merely on the crunching sounds the rays make when they crush a mollusk shell. From
