Fig 1. Predicted body condition indices (mass:foot) for black-tailed prairie dogs at South Exclosure and Big Foot Road colonies, South Dakota, USA, 2017.

At each colony, data were collected on paired sites treated with 0.005% fipronil (FIP) grain on 24 Jul or left non-treated. Data were collected during 3 BACI (before-after-control-impact) periods: Before FIP grain treatments (June-24 July), After-1 (25 July-30 August), and After-2 (1 September-October). Here, prairie dog ages/sexes are combined for simplicity. Error bars are ± 1 SE.
