Demographic effects of extreme weather events: snow storms, breeding success, and population growth rate in a long-lived Antarctic seabird
Abstract: Weather extremes are one important element of ongoing climate change, but their impacts ... growth rate. We used detailed data on daily individual nest survival in a year with frequent and heavy ... and overall productivity. Snow storm events explained 30% of the daily nest survival within the 2011/2012 ... season and nearly 30% of the interannual variation in colony productivity in period 1985–2014. Snow ...
