Research project

Indirect trophic links, migratory connectivity and seasonal interactions in High-Arctic nesting shorebirds.

Understanding migratory species population dynamic and empowering conservation measures requires the study of indirect trophic relationships, of migratory connectivity and of seasonal interactions. These concepts have received little attention in the past in migratory species. This thesis is covering theses themes using shorebirds (waders) as focal species. Shorebirds are a group of migratory bird species presenting high conservation concerns. About 80% of the Canadian populations are considered declining and this decline is still unexplained.

This thesis has for general goal to look at some factors that may have a demographic impact on shorebirds, especially on a focal species: the American Golden-Plover (Pluvialis dominica). The specific goals are:
1- To establish the existence of indirect trophic lings between prey species (lemmings, geese, shorebirds).
2- To describe American Golden-Plover space use throughout the year for several Arctic nesting population to assess their level of migratory connectivity.
3- To relate plovers migration strategy (phenology, speed, distance) with phenology and reproductive success of individuals.

Methodology: We will use data coming from artificial nest experiments measuring predation risk on shorebird nests and from observations made on transects to establish spatial variations in predators and preys on Bylot Island (2010 to 2014). Logistical statistical models will be used to investigate relationships between main prey (lemmings) and alternative prey abundance (goose) with predation risk on shorebird nests. Using data loggers (geolocators), migration data of plovers nesting in several Nordic sites (Alaska, Alberta, Manitoba and Nunavut) will be available. Migratory stopovers and wintering sites will be defined with kernels. They will then be compared to look at the level of segregation of plovers nesting at different locations. Linear and logistic mixed models will be used to investigate the individual relationships between migratory path parameters (phenology, speed, and distance of the migration). In a context of accelerated changes in the Arctic, it is important to shed light on factors explaining distribution and abundance of species, in the hope of assuring the conservation of biodiversity. Studying trophic links in the tundra is essential to better anticipate impacts of environmental changes, including variation in the abundance of species and colonization of new ones. Describing migration paths and their impact on the reproduction will help for population management and validate theories about migratory connectivity and seasonal interactions in migratory birds.
