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

description: 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.

The breeding population survey is annually conducted to estimate population size of these species among ecostratum.   crop.RData – Proportion of each ecostratum (Alberta parkland [ABK], Alberta prairie [ABP], Saskatchewan parkland [SKK], Saskatchewan prairie [SKP], Manitoba parkland [MBK], US prairie [USP]) in conservation tillage (a measure of agricultural intensification) for years 1961-2019.   grss.RData – Proportion of each ecostratum (Alberta parkland [ABK], Alberta prairie [ABP], Saskatchewan parkland [SKK], Saskatchewan prairie [SKP], Manitoba parkland [MBK], US prairie [USP]) in grassland for years 1961-2019.   prec.RData – Mean winter (October to February) precipitation for Pacific Coast (PC) and southern US/Lower Mississippi Valley/Gulf Coast (GC).   rice_data.RData – The total hectares of rice planted in the United States annually 1961-2021, and the hectares of flooded rice in Pacific Coast (CV) and southern US/Lower Mississippi Valley/Gulf Coast (GC).
