    Characterization of MHC class I in a long distance migratory wader, the Icelandic black-tailed godwit 
    Pardal, Sara; Drews, Anna; Alves, Jose; Ramos, Jaime A.; Westerdahl, Helena (Springer Nature, 2017-05-23)
    The major histocompatibility complex (MHC) encodes proteins that are central for antigen presentation and pathogen elimination. MHC class I (MHC-I) genes have attracted a great deal of interest among researchers in ecology and evolution and have been ...

    Consequences of population change for local abundance and site occupancy of wintering waterbirds 
    Méndez, Verónica; Gill, Jennifer A.; Alves, Jose; Burton, Niall H. K.; Davies, Richard G. (Wiley-Blackwell, 2017-09-20)
    Aim Population size changes can lead to changes in local abundance and/or site occupancy, depending on the processes influencing site use by individuals. Here, we quantify such changes for wintering waterbirds and assess their implications for widely ...

    Linking warming effects on phenology, demography, and range expansion in a migratory bird population 
    Alves, Jose; Gunnarsson, Tomas Gretar; Sutherland, William J.; Potts, Peter M.; Gill, J. A. (Wiley, 2019-02-14)
    Phenological changes in response to climate change have been recorded in many taxa, but the population-level consequences of these changes are largely unknown. If phenological change influences demography, it may underpin the changes in range size and ...

    Linking Weather and Phenology to Stopover Dynamics of a Long-Distance Migrant 
    Carneiro, Camilo; Gunnarsson, Tomas Gretar; Alves, Jose (Frontiers Media SA, 2020-06-04)
    For many migratory species, migration can represent a significant part of the annual cycle and the strategies used to move between the breeding and non-breeding areas vary considerably. Weather conditions are important during migration, particularly ...

    Low fitness at low latitudes: Wintering in the tropics increases migratory delays and mortality rates in an Arctic breeding shorebird 
    Reneerkens, Jeroen; Versluijs, Tom S. L.; Piersma, Theunis; Alves, Jose; Boorman, Mark; Corse, Colin; Gilg, Olivier; Hallgrimsson, Gunnar Thor; Lang, Johannes; Loos, Bob; Ntiamoa‐Baidu, Yaa; Nuoh, Alfred A.; Potts, Peter M.; Horn, Job; Lok, Tamar (Wiley, 2019-10-04)
    Evolutionary theories of seasonal migration generally assume that the costs of longer migrations are balanced by benefits at the non-breeding destinations. We tested, and rejected, the null hypothesis of equal survival and timing of spring migration ...

    Population structure of Purple Sandpipers (Calidris maritima) as revealed by mitochondrial DNA and microsatellites 
    LeBlanc, Nathalie M.; Stewart, Donald T.; Pálsson, Snæbjörn; Elderkin, Mark F.; Mittelhauser, Glen; Mockford, Stephen; Paquet, Julie; Robertson, Gregory J.; Summers, Ron W.; Tudor, Lindsay; Mallory, Mark L. (Wiley-Blackwell, 2017-03-31)
    The Purple Sandpiper (Calidris maritima) is a medium-sized shorebird that breeds in the Arctic and winters along northern Atlantic coastlines. Migration routes and affiliations between breeding grounds and wintering grounds are incompletely understood. ...

    Reconciling biodiversity conservation and agricultural expansion in the subarctic environment of Iceland 
    Johannesdottir, Lilja; Alves, Jose; Gill, Jennifer A.; Gunnarsson, Tomas Gretar (Resilience Alliance, Inc., 2017)
    Intensified agricultural practices have driven biodiversity loss throughout the world, and although many actions aimed at halting and reversing these declines have been developed, their effectiveness depends greatly on the willingness of stakeholders ...

    Use of agricultural land by breeding waders in low-intensity farming landscapes 
    Johannesdottir, Lilja; Alves, Jose; Gill, J. A.; Gunnarsson, Tomas Gretar (Wiley, 2017-12-21)
    Agriculture is one of the primary threats to biodiversity but agricultural land can also provide key resources for many species and, in some parts of the world, agricultural land supports important populations of species of conservation concern. In ...

    Vegetation structure influences predation rates of early nests in subarctic breeding waders 
    Laidlaw, Rebecca; Gunnarsson, Tomas Gretar; Méndez Aragón, Verónica; Carneiro, Camilo; Þórisson, Böðvar; Wentworth, Adam; Gill, Jennifer A.; Alves, Jose (Wiley, 2020-03-13)
    Ground-nesting species are vulnerable to a wide range of predators and often experience very high levels of nest predation. Strategies to reduce nest vulnerability can include concealing nests in vegetation and/or nesting in locations in which nests ...

    Very rapid long-distance sea crossing by a migratory bird 
    Alves, Jose; Dias, Maria P.; Méndez, Verónica; Katrínardóttir, Borgný; Gunnarsson, Tomas Gretar (Springer Nature, 2016-11-30)
    Landbirds undertaking within-continent migrations have the possibility to stop en route, but most long-distance migrants must also undertake large non-stop sea crossings, the length of which can vary greatly. For shorebirds migrating from Iceland to ...
