Study:Stopover use of an internationally important wetland, the Tagus estuary, by a long-distance migratory shorebird
This new study compares the stopover ecology of Dunlins (Calidris alpina) between spring and autumn migrations at a key wetland of the East Atlantic Flyway, the Tagus estuary (Portugal). Dunlins are long distance migratory shorebirds, using the Tagus estuary both as a non-breeding area and as a stopover area during spring and autumn migrations. During spring, ca. 30,000 dunlins use the Tagus estuary as a stopover site for an average period of 7.5 days. Population size and stopover length of autumn migrants is unknown, but numbers recorded in a long-term monitoring program based on monthly high-tide counts suggest that similar populations may be involved in spring and autumn migration periods. In this study, plasma metabolite levels and haematological parameters were combined to compare refuelling rates and physiological state of dunlins within and between migratory periods. Additionally, as a proxy for site quality, food availability and feeding performance of migrants were assessed and compared in spring and autumn. Refuelling rates and haematological profiles of dunlins were overall similar during spring and autumn, suggesting similar migratory strategies and providing no support for the hypothesis that time constrains are greater during spring. Most dunlins stopping over at the Tagus estuary are likely to follow a skipping migratory strategy, flying short-to-medium distance bouts while fuelling at moderate rates along a network of stopover sites. Early-autumn migrants, however, display higher fuel deposition rates and enhanced blood oxygen-carrying capacity, which suggests they may behave as jumpers rather than skippers. This study was carried out by Teresa Catry (CESAM-UL), José Pedro Granadeiro (CESAM-UL), Jorge Sánchez Gutiérrez (University of Extremadura) and Edna Correia (CESAM-UL), as part of the project MigraWebs (FCT, PTDC/BIA-ECO/28205/2017).

World Wetlands Day 2022
According to the Ramsar Convention, wetlands are “areas of marsh, fen, peatland, or water, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish, or salt including areas of marine water, the depth of which at low tide does not exceed 6 meters”. Wetlands play a vital role for people and the planet, helping combat climate change through carbon sequestration and climate regulation, contributing to the supply and improving the quality of brackish and freshwater, and supporting biodiversity. However, wetlands (including coastal wetlands, such as seagrass meadows and salt marshes) are under threat, mainly due to human activities. Land-use changes, pollution, salinization, urbanization, and invasive species, associated with climate change impacts, have contributed to the degradation of these areas, with negative consequences for biodiversity, ecosystem services and human health. This year an appeal is launched to invest financial, human, and political capital to save the world’s wetlands from disappearing and to restore those we have degraded. To mark World Wetlands Day 2022, we highlight the GLOW - The Global Wetlands Project - A global index to improve coastal wetland health, an international project of which CESAM is a partner. GLOW aims to build a new index of coastal wetland health (including seagrass meadows, mangrove forests and saltmarshes), which can be applied at the global scale, and use it to inform protection and restoration. Ria de Aveiro coastal lagoon is one of the six global partner sites of the GLOW project. Learn more about the GLOW project here and here.
