PhD candidate Anne-Fleur Brand talks about shorebirds

Sammendrag

Shorebirds are famous for their globe-spanning migrations, with some species crossing astonishing distances of over 11,000 km in a single flight. They form an integral part of almost all ecosystems in the world, transporting nutrients, energy, and other organisms between these interconnected systems. The East Asian-Australasian Flyway (EAAF) is one of the nine major migration routes around the world, extending all the way from Arctic Russia and North America (breeding grounds) southwards to East Asia and Australia (wintering, non-breeding grounds). Every year, millions of shorebirds migrate along this flyway. Unfortunately, data shows that populations of shorebirds that migrate along the EAAF are drastically decreasing and there is widespread concern that significant habitat degradation and pollution are driving these declines. The decline of shorebirds along the EAAF is the proverbial canary in the coal mine. Pollutant exposure has been linked to immunosuppression and disease outbreaks in various wildlife species. Yet, it remains unclear how pollutants exactly cause disease. Recently, microRNAs have been identified as important regulators of the immune response and important determinants of disease outcomes. MicroRNAs are a class of small noncoding RNAs that bind specific mRNA transcripts and prevent their translation into proteins. Changes in microRNA expression have been found after exposure to various pollutants and might therefore be a missing link in our understanding of how pollutants promote disease. As part of the COAST IMPACT project, we study the potential of microRNAs in blood as indicators of pollution exposure and disease in migratory shorebirds. The identification of specific microRNA profiles associated with pollution exposure could help us monitor negative impacts of pollution in species of conservation concern.
