Thus, as described in other cross-sectional, but also longitudinal studies, living in families with non-biological children, with or without additional biological children, does not seem to be particularly burdensome, aside from a generally lower SES in these types of family constellations (18, 20, 50), while living without a partner seems to be specifically burdensome in custodial fatherhood (8).

Sample text:```By clustering with lowly aggressive close kin (King 1989a,b; Viblanc et al. 2010; Arnaud, Dobson & Murie 2012), breeding females may decrease the time/energy cost of maintaining territorial boundaries (Festa-Bianchet & Boag 1982; Murie & Harris 1988), which could ultimately lead to increases in net energy income (TA) or higher allocations in somatic or reproductive functions.```
