Lay_date_summary: Primary data used as the basis for all analysis

In LiamDBailey/baileyetal2021: Bird populations most exposed to climate change are less sensitive to climatic variation

Description

Note, in Vlieland and Sicily there are years where phenological data is available but full temperature data is not. In these cases, Temp is NA.

Format

A data frame with 2,010 rows and 10 columns

Pop_ID

Mean

Mean laying date (April days).

SE

Standard error of mean laying date (April days).

Min

Minimum observed laying date (April days).

Count

Total number of first nests laying date records for this population/species/year combination.

Date

Starting date used sliding window analysis (dd/mm/yyyy).

SE_calc
