Ecological and anthropogenic drivers of waterfowl productivity are synchronous across species, space, and time

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 pro..., , , # Data from: Ecological and anthropogenic drivers of waterfowl productivity are synchronous across species, space, and time

## Description of the data and file structure

model_code.R – Includes all code to read in data files and run models to quantify drivers of productivity in six species of dabbling ducks in North America (American wigeon, blue-winged teal, gadwall, green-winged teal, mallard and northern pintail).
 
band.RData – The annual number of banded juvenile (juv) and adult (ad) American wigeon (amwi), blue-winged teal (bwte), gadwall (gadw), green-winged teal (gwte), mallard (mall) and northern pintail (nopi), according to ecostratum (Alberta parkland [ABK], Alberta prairie [ABP], Saskatchewan parkland [SKK], Saskatchewan prairie [SKP], Manitoba parkland [MBK], US prairie [USP]) for years 1961-2019.
 
bpop.RData – Breeding population survey data for American wigeon (amwi), blue-winged teal (...
