Molecular data for analysing avian diversification across the Australasian archipelago

Projektet skal udnytte den unikke mulighed for helikopter-adgang til uudforskede steder i Indonesien og Melanesien, for indsamling af data til Zoologisk Museums globale analyse af evolution af spurvefuglene. Dette sker i samarbejde med flere andre institutioner og vil indgå i et globalt initiativ for at oparbejde DNA-"barcodes" for alle verdens fugle. ZM har allerede verdens næststørste samling af prøver for DNA-analyse af fugle, men generelt er der stor mangel på sådant materiale fra det Indoaustralske ø-område. Studier af fugle fra denne region var af central betydning for udvikling af det biologiske artsbegreb og vor forståelse af hvordan nye arter opstår. Disse ideer synes imidlertid at bygge på nogle fejltolkninger. Med en molekylærbiologisk tilgang, og et udvidet forskningssamarbejde, forventer vi at opnå en dybere forståelse af en af de mest dynamiske faser i fuglenes evolution.

The project is to take advantage of the unique opportunity for helicopter access to unexplored places in Indonesia and Melanesia to collect data for the Zoological Museum global analysis of the evolution of passerine birdssparrows, wich comprise more than half of the world’s bird species. This is done in cooperation with several other institutions, and will form part of a global initiative to establish records on DNA "barcodes" for all the birds of the World. The ZM has already one of the World’s second-largest collection of samples DNA samples analysis of birds, but there is generally a great shortage of such material from the Indo-PacificAustralian Archipelago. Studies of birds from this region were of key significance for the development of the biological concept of species and our understanding of the way in which new species arise. These ideas seem, however, to be built on a number of flawed interpretations. With the application of a molecular -biological approach and extended scientific research cooperation, we expect to achieve deeper understanding of one of the most dynamic phases in the evolution of birds.
