    Soil nematode communities on Surtsey, 50 years after the formation of the volcanic island 
    Ilieva-Makulec, Krassimira; Bjarnadóttir, Brynhildur; Sigurdsson, Bjarni D. (Agricultural University of Iceland, 2015)
    Soil nematodes are a key group that can both influence and reflect changes in the soil ecosystem. We investigated the generic composition, abundance and community structure of soil nematodes in two contrasting vegetation successional seres now found ...

    Temperature effects on fish production across a natural thermal gradient 
    O'Gorman, Eoin J.; Ólafsson, Ólafur P.; Demars, Benoît O. L.; Friberg, Nikolai; Guðbergsson, Guðni; Hannesdóttir, Elísabet R.; Jackson, Michelle C.; Johansson, Liselotte S.; McLaughlin, Órla B.; Ólafsson, Jón S.; Woodward, Guy; Gislason, Gisli Mar (Wiley-Blackwell, 2016-03)
    Global warming is widely predicted to reduce the biomass production of top predators, or even result in species loss.Several exceptions to this expectation have been identified, however, and it is vital that we understand the underlyingmechanisms if we ...

    Understanding how birds rebuild fat stores during migration: insights from an experimental study 
    Araújo, Pedro M.; Viegas, Ivan; Rocha, Afonso D.; Villegas, Auxiliadora; Jones, John G.; Mendonça, Liliana; Ramos, Jaime A.; Masero, José A.; Alves, Jose (Springer Science and Business Media LLC, 2019-07-11)
    Mechanisms underlying fat accumulation for long-distance migration are not fully understood. This is especially relevant in the context of global change, as many migrants are dealing with changes in natural habitats and associated food sources and ...

    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 ...

    Variation in the magnitude of morphological and dietary differences between individuals among populations of small benthic Arctic charr in relation to ecological factors 
    Kristjansson, Bjarni K.; Leblanc, Camille (Wiley-Blackwell, 2018-01-03)
    The early stages of intraspecific diversity are important for the evolution of diversification and speciation. Early stages of diversification can be seen in individual specialization, where individuals consume only a portion of the diet of the population ...

    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 ...

    Weed suppression greatly increased by plant diversity in intensively managed grasslands: A continental-scale experiment 
    Connolly, John; Sebastià, Maria-Teresa; Kirwan, Laura; Finn, John Anthony; Llurba, Rosa; Suter, Matthias; Collins, Rosemary P.; Porqueddu, Claudio; Helgadóttir, Áslaug; Baadshaug, Ole H.; Bélanger, Gilles; Black, Alistair; Brophy, Caroline; Čop, Jure; Dalmannsdottir, Sigridur; Delgado, Ignacio; Elgersma, Anjo; Fothergill, Michael; Frankow-Lindberg, Bodil E.; Ghesquiere, An; Golinski, Piotr; Grieu, Philippe; Gustavsson, Anne-Maj; Höglind, Mats; Huguenin-Elie, Olivier; Jørgensen, Marit; Kadziuliene, Zydre; Lunnan, Tor; Nykanen-Kurki, Paivi; Ribas, Angela; Taube, Friedhelm; Thumm, Ulrich; De Vliegher, Alex; Lüscher, Andreas (Wiley, 2017-09-27)
    Grassland diversity can support sustainable intensification of grassland production through increased yields, reduced inputs and limited weed invasion. We report the effects of diversity on weed suppression from 3 years of a 31-site continental-scale ...
