Scientists explore the oceans! They collect dolphin droppings one by one

The lives of bottlenose dolphins living in Cardigan Bay, Wales, are being studied more closely thanks to an interesting method used by scientists . According to SkyNews; The poop left by the dolphins under the waves is being collected and DNA analyses are being conducted, thus providing new information about the mysterious world of these marine mammals. Previously only observable when they surface, the lives of dolphins are now being revealed in much more detail thanks to the genetic traces in their poop.
Identity and Feeding Habits of Dolphins Through DNA AnalysisDNA obtained from collected fecal samples not only determines the sex of the dolphins, but also reveals the relationships between individuals. In addition, these analyses provide important clues about the dolphins’ feeding habits by showing what kind of fish they feed on. In particular, answers are being sought to questions such as how dolphins’ diets change during different seasons of the year and what kind of fish young dolphins need. This data is critical for understanding the dolphins’ life cycle and ecological needs.
Collecting dolphin feces is not easy. The animals leave their feces while swimming in the water, but this waste material quickly sinks to the seabed. In order to catch this cloud of feces, scientists have to be very close with their boats and use special nets with fine mesh. The collected samples are immediately sent to the laboratory for DNA analysis. This meticulous work stands out as a very innovative method for understanding the marine ecosystem.
Dolphins' Response to Climate ChangeThe research also provides important information about how dolphins are adapting to the effects of climate change. In recent years, there has been an increase in the number of certain fish species off the coast of Wales, such as sardines, sprats and anchovies. Marine biologist Dr. Niall McKeown says these species are becoming more common among dolphins’ food sources. This change is an important indicator of how dolphins are adapting to fluctuations in sea temperatures.
Alarming Decline in Dolphin PopulationThe decrease in the number of dolphins in Cardigan Bay has raised questions in the minds of scientists. It is not yet clear whether this decrease is a natural cycle or a problem caused by human influences. It is thought that the noise made by boats and fishing activities on the seabed in particular have a negative impact on the communication and social life of dolphins. It is estimated that these creatures, who communicate through sound, are struggling due to environmental stress factors.
More Information is Needed to Protect NatureDr Sarah Perry says that Cardigan Bay is a great opportunity to host such a significant dolphin population. However, she stresses that there are still many unknowns about this valuable species and that more comprehensive data is needed for conservation efforts. Understanding dolphins’ lives below the waves is seen as one of the critical steps to saving them from extinction. This research is seen as a significant milestone in the sustainability of marine ecosystems and the preservation of biodiversity.
