We used hierarchical random-effects models to examine interspecific and
spatial variation in annual productivity in six migratory ducks (i.e.,
American wigeon [Mareca americana], blue-winged teal [Spatula discors],
gadwall [Mareca strepera], green-winged teal [Anas crecca], mallard [Anas
platyrhynchos] and northern pintail [Anas acuta]) across six distinct
ecostrata in the Prairie Pothole Region of North America (Alberta
parkland, Alberta prairie, Saskatchewan parkland, Saskatchewan prairie,
Manitoba parkland, US prairie). We tested whether breeding habitat
conditions (seasonal pond counts, agricultural intensification, and
grassland acreage) or cross-seasonal effects (indexed by flooded rice
acreage in primary wintering areas) better explained variation in the
proportion of juveniles captured during late summer banding. This
submission comprises model code and data of banded birds by species,
breeding population survey by species, proportion of ecostratum in
conservation tillage (a proxy for agriculutral intensification),
proportion of ecostratum in grassland, mean winter precipitation for
Pacific Coast and Gulf Coast, total hectares of rice planted in the US, as
well as hectares of flooded rice in the Pacific Coast and Gulf Coast.
