Species and landscape metrics.

Values for simulated species around rural property locations in Amapá, Brazil.

Abundances and presence absence of 11 species simulated using package virtualspecies . The species have contrasting responses to forest cover. The response patterns follow those known for primate and carnivore species (Michalski & Peres 2005; Michalski & Peres 2007).

Values for one metric cpland calculated using package landscapemetrics. cpland is the percentage of core area of class in relation to the total landscape area. Landscape metric from MapBiomas forest cover class. Metrics are calculated around each property in buffers with radius of: 0.125, 0.25, 0.5, 1, 2, 4, 8 and 16 km. To reduce influence of satellite image quality, the metric values are median values from three years: study year, year before and year after.
