Adult sex ratio variation of Svalbard reindeer in relation to animal density and climate, RIS ID: 6169.

In this study I will estimate adult sex ratio in Svalbard reindeer and examine to what degree the variation can be explained by environmental conditions, i.e. weather and food availability. To obtain this, I will analyze spatiotemporal variation in sex ra tios from long-term monitoring data of multiple Svalbard reindeer populations covering gradients in environmental conditions and historical grazing pressure. I will also estimate and account for the uncertainties in sex ratios that are due to observer eff ects.
