Evidence for Cross-Seasonal Effects: Insights from Long-term Data on Northern Pintail

Creator:: Zarzycki, Megan C.
Abstract:: Cross-seasonal effects, where conditions in one season can have consequences in a following season, can have population-level implications for migratory species. To assess the presence of cross-seasonal effects on a migratory dabbling duck population, we examined the relative importance of habitat conditions in multiple seasons on the subsequent productivity of...
