Ferreira1*, Jocelyn Champagnon1, Irene Badone1, Arnaud Béchet1 and Oscar S. Macouzet1 1 Tour du Valat, France Environmental influences at early growth stages are increasingly well documented across a variety of taxa and often involve life-lasting developmental effects. Nevertheless, it is still not clear how most of the natural environmental stressors accrue, and how the organisms cope and respond to such environmental pressures in the wild. In animals, body condition indexes provide excellent metrics of how individuals respond to their environment, but their typical use tends to focus on single environmental variables that portrait an unrealistic uni-variate environment. In this study, our aim was to assess the multi-variate effects of a complex coastal environment on the condition attained by chicks of a focal colonial waterbird species: the Glossy Ibis Plegadis falcinellus. Specifically, we studied chicks from a growing breeding colony in the Camargue, in southern France, where the number of breeding pairs has increased from 14 in 2006, to more than 2,000 through to this day. This coastal region hosts one of the largest Mediterranean wetlands of Europe and is an important hotspot for hundreds of breeding and migratory species that profit from its high marine connectivity and coastal water dynamics. We first quantified inter-annual variation on the body condition of chicks over a 12-year long-term study period (from 2006 to 2018), while assessing the potential variation within each year owing to seasonal effects. We then tested for interacting effects of three locally relevant environmental parameters of interest in this coastal environment (the mean temperature, the rainfall and the wind) on the condition attained by the chicks of our focal species. We present and discuss our results in the light of coastal environment complexity and its relevance for coastal wetlands and waterbirds.
