Reproduction within taxon-pairs.

<p>Mean litter or clutch size (± SE) for taxon-pairs with a minimum of three independent observations per taxon. For each taxon-pair, bars with different letters are significantly different (shaded bars = threatened and endangered subspecies; white bars = non-listed subspecies; p<0.05). Taxon-pairs are labeled according to the federally listed subspecies: <i>Pcc</i> = <i>Puma concolor coryi</i>, <i>Ppp</i> = <i>Peromyscus polionotus phasma</i>, <i>Asf</i> = <i>Ammodramus savannarum floridanus</i>, <i>Amm</i> = <i>Ammodramus maritimus mirabilis</i>, <i>Ppa</i> = <i>Polyborus plancus audubonii</i>, <i>Rsp</i> = <i>Rostrhamus sociabilis plumbeus</i>.
