Long-Term Regenerative Defects Inhibit Male Spawning (A) Whole-mount images of pectoral fins at 2 months postamputation (mpa). Good indicates that all fin rays between the first to sixth fin rays have completely regenerated. Mild indicates that one to three fin rays between the first to sixth fin rays show defective regeneration. Severe indicates that at least four of six fin rays between the first to sixth fin rays failed to regenerate normally. Arrowheads indicate amputation planes. Scale bars, 500 μm. (B) Cartoon summarizing experiments in which mating tests were performed 1–2 months after amputation. (C) Pie charts with results of mating tests 1–2 months after amputation of caudal or pectoral fins, with each pectoral fin scored after mating as in (B). Males that regenerated more effectively stimulated better laying than those with defective regeneration. n = 13 to 75 animals. The top p value is calculated from Fisher’s exact test between the no-amputation control and the experimental group for the percentage of successful matings, with one embryo or more considered successful (none versus more than one embryo). The bottom p value is calculated from Fisher’s exact test between the no-amputation control and the experimental group for the percentage of successful matings, with ten or more embryos considered successful (zero to ten embryos versus more than ten embryos). |
