Data from figures 3 and 4 of Nicholson, 1954.

`bf1` |
the dataset name |

`bf1`

is Nisbet and Gurney's run 1, and Nicholson's (1954) figure 3 (adult food limitation). The
data are actually from the global population dynamics database at Silwood. They are daily: Nicholson's figure 3
plots data every other day, but the text says that measurements were taken daily. However elsewhere they are
reported every other day. Probably best to assume that they have been interpolated to daily.

`bf2`

and `bf3`

are digitized from Nicholson's (1954) figure 4. `bf2`

is the upper series:
larval food limitation, with 50g per day of larval food provided. `bf3`

is the lower series: same set up, half as much food.
These are Nisbet and Gurney's runs 2 and 3, respectively.
