We manipulated social group size (i.e., monogamous and promiscuous regimes) and density (i.e., 4 levels) using a full-factorial design, to identify the underlying factor affecting female allocation (in terms of egg production) and body growth. …”

Intact nuclei were extracted by treatment with acidified NH(4)F solution combined to low intensity sonication pulses and separated from cell debris via FAC-sorting upon incubation with SYBR Green. …”

These groups span a gradient of anthropogenic habitat disturbance, including groups in continuous forest (‘CONT’) and disturbed fragments (‘FRAG’), and indicators of health suggest that FRAG groups are negatively impacted by habitat disturbance. …”
