Update 1. Guanaco population abundance, sheep population abundance, estimated population annual rate of growth, average annual precipitation, and average winter temperature of the Cameron ranch, Tierra del Fuego.

Guanaco population abundance (individuals), lower and upper limits of the 95% confidence intervals (CI), sheep population abundance (individuals), estimated population annual rate of growth (l), average annual precipitation (P; mm/year), and average winter temperature (degrees Celsius). Guanaco population values were not available for years 1986 and 1996, and were linearly interpolated (using the values of the previous and following years); sheep population values were only available for years 1980, 1985, 1990, 1995, 2000, 2005, 2008 and 2011; and the missing years were also linearly interpolated. Data has been updated in following columns: sheep population [ranges of changed values are only for years: 1981-1984; 1986-1989; 1991- 1994; 1996-1999; 2001-2004; 2006-2007, 2009-2010]; data of winter temperature (Av winter temp); annual precipitation (P) [ranges of changed values are only for years: 2003-2011].
