    • Annual adult survival drives trends in Arctic-breeding shorebirds but knowledge gaps in other vital rates remain 

      Weiser, Emily L.; Lanctot, Richard B.; Brown, Stephen C.; Gates, H. River; Bêty, Joël; Boldenow, Megan L.; Brook, Rodney W.; Brown, Glen S.; English, Willow B.; Flemming, Scott A.; Franks, Samantha E.; Gilchrist, H. Grant; Giroux, Marie-Andrée; Johnson, Andrew; Koloski, Laura; Kwon, Eunbi; Lamarre, Jean-François; Lank, David B.; Latty, Christopher J.; Lecomte, Nicolas; Liebezeit, Joseph R.; McGuire, Rebecca L.; McKinnon, Laura; Nol, Erica; Payer, David; Perz, Johanna; Rausch, Jennie; Robards, Martin; Saalfeld, Sarah T.; Senner, Nathan R.; Smith, Paul A.; Soloviev, Mikhail; Solovyeva, Diana; Ward, David H.; Woodard, Paul F.; Sandercock, Brett; Kendall, Steve (Peer reviewed; Journal article, 2020)
      Conservation status and management priorities are often informed by population trends. Trend estimates can be derived from population surveys or models, but both methods are associated with sources of uncertainty. Many ...

    • Breeding populations of Marbled Godwits and Willets have high annual survival and strong site fidelity to managed wetlands 

      Sandercock, Brett; Gratto-Trevor, Cheri L. (Peer reviewed; Journal article, 2023)
      The Prairie Pothole Region of central Canada supports a diverse community of breeding waterbirds, but many species have declining populations and the demographic mechanisms driving the declines remain unknown. We conducted ...

    • Context-dependent demographic and genetic effects of translocation from a captive breeding project 

      Wallen, Johan; Norén, Karin; Angerbjörn, Anders; Eide, Nina Elisabeth; Landa, Arild; Flagstad, Øystein (Peer reviewed; Journal article, 2022)
      Translocations are a widespread approach to conserve threatened populations. Given the rapid decline and genetic deterioration of many natural populations, translocations are expected to become even more common in the ...

    • Exceptionally high apparent adult survival in three tropical species of plovers in Madagascar 

      Jones, William; Eberhart-Hertel, Luke J.; Freckleton, Robert P.; Hoffman, Joseph I.; Krüger, Oliver; Sandercock, Brett; Vincze, Orsolya; Zefania, Sama; Székely, Tamás (Peer reviewed; Journal article, 2021)
      Adult survival is a key component of population dynamics, and understanding variation in and the drivers of adult survival rates and longevity is critical for ecological and evolutionary studies, as well as for conservation ...

    • Population fitness has a concave relationship with migration distance in Sanderlings 

      Sandercock, Brett (Peer reviewed; Journal article, 2020)
      n Focus: Reneerkens, J., Versluijs, T. S. L., Piersma, T., Alves, J. A., Boorman, M., Corse, C., ... Lok, T. (2020). Low fitness at low latitudes: wintering in the tropics in-creases migratory delays and ...

    • Predation, parasitism, and drought counteract the benefits of patch-burn grazing for the reproductive success of grassland songbirds 

      Verheijen, Bram H. F.; Erickson, Amy N.; Boyle, W. Alice; Leveritte, Kiana S.; Sojka, Jennifer L.; Spahr, Lauren A.; Williams, Emily J.; Winnicki, Sarah K.; Sandercock, Brett (Journal article, 2022)
      Intensification of livestock production has reduced heterogeneity in vegetative structure in managed grasslands, which has been linked to widespread declines in grassland songbird populations throughout North America. ...

    • The role of seasonal migration in spatial population synchrony 

      Martin, Ellen Claire; Hansen, Brage Bremset; Herfindal, Ivar; Lee, Aline Magdalena (Peer reviewed; Journal article, 2023)
      Spatially synchronized population dynamics are common in nature, and understanding their causes is key for predicting species persistence. A main driver of synchrony between populations of the same species is shared ...

    • Survival estimates strongly depend on capture–recapture designs in a disturbed environment inducing dispersal 

      Ponchon, Aurore; Choquet, Rémi; Tornos, Jéremy; McCoy, Karen D.; Tveraa, Torkild; Boulinier, Thierry (Journal article; Peer reviewed, 2018)
      Capture-Recapture (CR) approaches are extensively used to estimate demographic parameters. Their robustness relies on the selection of suitable statistical models, but also on the sampling design and effort deployed in the ...
