The relationship between survivorship, net reproductive rate, and matriline size by site. The relationships are described by significant second order polynomials. For survivorship, Y = −0.553 + 1.248X − 0.311X2; P = 0.006, R2 = 0.67; for Ro, Y = −2.388 + 3.281X − 0.865X2; P = 0.018, R2 = 0.59. The names of the 12 sites where matrilines were observed are abbreviated on the figure: CC, Copper Creek; BR, Beaver Talus; NP, North Picnic; RA, River Annex; BD, Bend; MM, Marmot Meadow; UP, Upper Picnic; CL, Cliff; GO, Gothic Townsite; LP, Lower Picnic; BO, Boulder; RI, River.
