Накратко на български
Седиментите в езерата разкриват как минали суша или по-кратко ледено покритие са повлияли на популациите от водни птици. Анализът помага да се разберат настоящите промени в екосистемите и да се предвидят бъдещи тенденции за тези видове.

Paleoenvironmental Assessment of climate and other STressors on long-term dynamics of waterbird populations.
This project is mainly focused on the study of how past droughts and other climatic stressors have affected long-term dynamics of bird populations using paleolimnological approaches. Due to climate change, different areas and biomes of the world are being affected in such different manners. As an example, areas from the south of Spain are currently suffering the impact of longer periods of drought while lakes situated in the Arctic are strongly affected by shorter ice-cover periods. On the other hand, human activities have affected aquatic ecosystems in both direct and indirect ways, being them much more noticeable after the Industrial Revolution. Since inland waters of these regions are important habitats for waterbirds, their good conditions are essential for the survival of these animals. Lakes’ sediments act as archives of information of past conditions, so by studying them we may be able to reconstruct the past environmental conditions as well as the long-term changes in bird populations. On this way, we can link both variables and identifying how different stressors affected to waterbirds in the past and, therefore, to speculate possible future trends for these and other species according with the expected climatic conditions. In addition, inland waters are of great importance for societies since they provide water resources and are essential for many recreation activities such as swimming, boating, or fishing. In addition, it is well-known that waterbirds had been and are of great importance for human communities around the world for their eggs, down and meat. For all that, knowing the past conditions of these ecosystems and bird populations are essential for being able to understand the present and future changes and for the implementation of measures for their mitigation. The objectives of this project are: (i)Trace the long-term environmental changes occurring before and after the Industrial Revolution by using climatic records; (ii) Track long-term changes in bird populations in different aquatic ecosystems by using paleolimnological techniques, with a focus on assessing the causes of the changes in the populations; (iii) identify which bird groups were more affected by droughts and (iv) provide long-term scenarios of changes in bird populations and use these data to better inform predictions about future changes linked to ongoing climate warming.

Цел на проекта
Anthropogenic climate change affects all countries and so societies need to begin adapting to the ongoing impacts of these changes. In addition, different biomes respond in distinctive ways to climatic warming. For instance, like oceans, Arctic lakes are strongly affected by shorter ice-cover periods, further decreasing albedo which further increases warming. On the other hand, lakes located in Mediterranean regions are experiencing a decrease in the inundation area and water storage due to the magnitude of the droughts. It is important to say that inland waters are recognised as important sentinels of climatic change and their sediments accumulate records of past environmental conditions. For this reason, we can use these sediment records to study the trends in environmental changes such as warming or wet periods that occurred in the past. Through paleolimnological analyses, past climate history information can be inferred to determine the timing and degree of change in lake ecosystems. Whilst monitoring data may be short, the paleolimnological approach allows for the study of many years of a lake’s history in a very cost and labour effective manner. Furthermore, inland waters are frequently nesting areas for migratory birds, and these water bodies are especially sensitive to droughts. For this reason, waterbirds may suffer major losses by limited food supplies and habitat, as well as increased disease due to overcrowding. By using paleolimnological approaches, new methodologies allow us to assess past drought periods along with the long-term changes in bird population.This is why the main objective of this proposal is to study how past droughts and other climatic extremes have affected long-term dynamics of bird populations using paleolimnological approaches in two areas that are being affected by environment change in such different manners: ponds on nesting islands in the Great Lakes region of Canada and the Mediterranean Region of Spain.
