University of Â鶹´«Ã½<\/span> at Hilo<\/a> conservation geneticist Jolene Sutton<\/strong><\/a> received a grant that will help discover why eggs have failed to hatch for two iconic endangered bird species\u2014the ʻalalā<\/span> (Hawaiian crow) and the kākāpō of New Zealand. Sutton, along with her colleagues at the University of Otago in New Zealand, the University of Sydney in Australia and San Diego Zoo Global, were awarded the three-year grant for $630,000 from the Marsden Fund for their research utilizing genome sequencing data. <\/p>\n

“In addition to sequencing every living individual and some of the birds that are no longer alive today, we\u2019re going to sequence embryos as well,” said Sutton. “Genetic material has been saved from eggs that didn\u2019t hatch, and we\u2019re interested in establishing whole genome resources for those. By comparing genomes of eggs that didn\u2019t hatch to genomes of individuals that did successfully hatch, we hope to identify genes associated with hatching failure.”<\/p>\n

In addition to positive ecological and cultural impacts, the research in recovering the two bird species will also have an educational benefit both at UH<\/abbr> Hilo and the University of Otago.<\/p>\n

“A lot of our research is being done with students,” said Sutton. “With the Marsden Funds, we\u2019ll continue to involve graduate as well as undergraduate students in this research–there\u2019s going to be a lot of data generated, so we\u2019re going to involve a lot of students in that research. Students and staff will get hands-on experience doing cutting-edge research with the latest bioinformatics tools, the latest genomics tools, and two species that are very iconic worldwide.”<\/p>\n

In discovering why eggs fail to hatch, conservation scientists will be able to overcome one of the most challenging barriers in conserving the species.<\/p>\n

“Their hatching failure is about 60 percent in ʻalalā<\/span> and about 50 percent in kākāpō, and if you compare that to most wild species, hatching failure is only around 10 to 20 percent,” said Sutton. “This inability to make it from an egg to a chick is one of the biggest barriers to their recovery, at least from a genetic basis.”<\/p>\n
