The Marine Conservation Organization of Namibia (OCN) warned before the sudden death of more than 7,000 sea lions: “We are on the cusp of disaster (Anopheles small) On the beach in Namibia, Africa. Currently, researchers are collecting evidence and tracking the coast with drones to try to figure out the cause of the ecological disaster at Pelicant Point. PelicantPoint is a tourist attraction known for its abundant presence of sea lions and dolphins.
After considering these assumptions, the cause may be found in hunger, because the fish on which these animals depend have migrated to other waters due to climate change. The levels of toxins present in the water or other diseases related to global warming and ocean acidification are also possible.
The affected species are marine mammals endemic to the coasts of South Africa and Namibia. During the breeding season (mid-November to early December), thousands of females are born in coastal colonies. The Namibian Dolphin Project said in a press release: “However, this year, females have reached the coast of Namibia so sparsely that hundreds, even thousands, have aborted.”
Therefore, the impact on seal cubs is of particular concern to experts.Organize by analyzing drone tracking photos alarm Estimates of the number of hatcheries “In our colony alone, the number of hatcheries has increased to more than 5,000”.
Mass deaths of premature babies
After a few days of studying the extraordinary mortality rates in Namibia and South Africa, concerns about this incident have become more serious. “Literally, thousands of seal pups were born prematurely and died almost immediately. This is a natural phenomenon, which means that when a pregnant woman feels that her reserves are insufficient, she can abort.” The organization said Explained in its network statement. “This situation will happen with a small number of specimens every year, but it will never be on this scale.”
Naudé Dreyer, an environmentalist from OCN, warned of the existence of dead seals off the coast of Namibia in September last year. He said: “I started to see some small incubators in late August, and in mid-September, I saw some incubators.” “Last week, I returned to Pelican Point and saw hundreds of fetuses in one day. . That was when the alarm went off.
Dreyer collaborated with Tess Gridley and Simon Elwen of the Namibian Dolphin Organization, and with the Department of Botany and Zoology at Stellenbosch University and Brett Gardner, a veterinarian in South Africa. Experts work around the clock, collecting samples and conducting field research using drones to measure the scope of what is happening and try to predict what might happen.
At the same time, scientists are still investigating another environmental disaster that occurred hundreds of kilometers away on the Kamchatka Peninsula in Russia last week, where highly toxic microalgae killed up to 95% of marine invertebrates.
A similar situation occurred in Cape Cross in 1994, when 10,000 sea lions and 15,000 fetuses died of starvation due to lack of fish and bacterial infections.
A certain number of deaths in a colony are a normal part of the life cycle. What is worrying here is that the number of simultaneous miscarriages is high. The impact of these deaths in the Pelican Point Colony and possibly beyond can last for years.
