spatExtinct-package: Spatial Interpolation of Extinction Dates from Sighting Data

Description Details Author(s) References

Description

The spatExtinct package is a tool for spatially-interpolated extinction estimators. The purpose of the package is twofold: to assign likely extinction dates across a landscape, and to identify potential areas of persistence for species of conservation concern with unknown extinction status.

Details

The sun above me and a concrete floor below

Scratch at the chain links, maybe bare my teeth for show

Fed twice a day, I don't go hungry anymore

Feel in my bones just what the future has in store

I pace in circles so the camera will see

Look hard at my stripes, there'll be no more after me

Laze by the shoreline while the sailors disembark

Scratch out a place to sit and rest down in the dark

Smell something burning downwind just a little ways

They set up camp and sing and sweat and work for days

I have no fear of anyone, I'm dumb and wild and free

I am a flightless bird and there'll be no more after me

In Costa Rica in a burrow underground

Climb to the surface, blink my eyes and look around

I'm all alone here as I try my tiny song

Claim my place beneath the sky but I won't be here for long

I sang all night, the moon shone on me through the trees

No brothers left and there'll be no more after me

–The Mountain Goats, "Deuteronomy 2:10"
