Description
Levin et al. 2002 studied the impacts of brook trout introduced for sport fishing
on native Chinook salmon. Whitlock & Shulter used a subset
of these data as an example in their textbook Analysis of Biological Data.
Usage
1
Format
A data frame, including:
- site
Name of study site or stream
- trout.PRES.ABS
Are brook trout present in the stream or absent from it?
- release
Number of Chinook salmon released
- recap
Number of juvenile chinook salmon "recaptured" by detecting their PIT tag; this was not reported in original paper but was estimated using published survival rate. The survival rate estiamted using mark-recapture methods to account for detection probabilities.
- surv
survival rate
