AntarcticBirds: Antarctic birds and climate change

In romunov/AED: Package Accompanying 'Mixed Effects Models and Extensions in Ecology with R'

Description

Antartic birds (Aptenodytes forsteri, Pygoscelis adeliae, Daption capense) and their phenological data along with some environmental data.

Usage

data("AntarcticBirds")

Details

Dataset contains information on three bird species frequenting Antartic, the Emperor penguin (Aptenodytes forsteri), Adelie penguin (Pygoscelis adeliae) and Cape petrel (Daption capense). Variables in the dataset include below variables. Arrival and laying times are days in the year.

• ArrivalAP: Arrival time of Adelie penguin to the breeding area

• LayingAP: Laying time of Adelie penguin

• ArrivalCP: Arrival time of Cape petrel to the breeding ground

• LayingCP: Laying time of Cape petrel

• ArrivalEP: Arrival time of Emperor penguin

• LayingEP: Laying time of Emperor penguin

• MSA: Methanesulfonic acid, a proxy for sea ice extent since satellite images are available only from 1970 onwards

• SOI: Southern oscillation index, also known as El Niño souther oscillation conditions. High positve values indicate La Niña and low negative values indicate El Niño, which have been shown to have impact on demographic rates and food resources of many animals, including seabirds.
