Sea turtle for seven species are in trouble, they are considered endangered or vulnerable to extinction as these animals have declined due to many threatening factors, and one of the factors is pathogens. The researchers in a study published January 21 in PLOS ONE, say there’s a couple more pathogens to worry about. There’s several report of a fungus, Fusarium solani, that it has infected sea turtle eggs and blamed for mass death rate in the nests of loggerhead sea turtle in Cape Verde in the Atlantic Ocean.
As a result of analysis, there were only two species — F. falciforme and
F. keratoplasticum — were always found in dead turtle eggs. These two fungal grow well for fungi coincide at temperature range as same as temperature for the development of sea turtle embryos, the temperature range is suitable for egg incubation to be ideal for pathogen growth and colonization. Anyway, turtle nests location also have significant relation with risk of becoming infected, since an unsuitable environmental conditions might against gas exchange through the shells of the eggs, leading to greater embryonic stress and possibly death. As a reason, the nests in region that were inundated with water, clay, or slit have higher death rate than other region out of these conditions. Moreover, dead eggs are probably more easily colonized by the fungi, and once the fungi get established, they can produce a lot of spores, colonize the live eggs in the nest and start killing those living eggs.
The inundated nests are more vulnerable is worrisome because climate change and continued habitat destruction will make sea turtles more likely to end up lay eggs in these less suitable spots. But if the programs can identify the locations where the fungal pathogens possibly become a problem, the scientist can efforts by removing eggs from those more vulnerable beaches and raise those eggs into baby turtles.
