title: Data from: Interannual variation in effective number of breeders and estimation of effective population size in long-lived iteroparous lake sturgeon (Acipenser fulvescens)

description: Quantifying interannual variation in effective adult breeding number (Nb)
 and relationships between Nb, effective population size (Ne), adult census
 size (N) and population demographic characteristics are important to
 predict genetic changes in populations of conservation concern. Such
 relationships are rarely available for long-lived iteroparous species like
 lake sturgeon (Acipenser fulvescens). We estimated annual Nb and
 generational Ne using genotypes from 12 microsatellite loci for lake
 sturgeon adults (n = 796) captured during ten spawning seasons and
 offspring (n = 3925) collected during larval dispersal in a closed
 population over 8 years. Inbreeding and variance Nb estimated using mean
 and variance in individual reproductive success derived from genetically
 identified parentage and using linkage disequilibrium (LD) were similar
 within and among years (interannual range of Nb across estimators:
 41–205). Variance in reproductive success and unequal sex ratios reduced
 Nb relative to N on average 36.8% and 16.3%, respectively. Interannual
 variation in Nb/N ratios (0.27–0.86) resulted from stable N and low
 standardized variance in reproductive success due to high proportions of
 adults breeding and the species' polygamous mating system, despite a
 40-fold difference in annual larval production across years (437–16 417).
 Results indicated environmental conditions and features of the
 species' reproductive ecology interact to affect demographic
 parameters and Nb/N. Estimates of Ne based on three single-sample
 estimators, including LD, approximate Bayesian computation and sibship
 assignment, were similar to annual estimates of Nb. Findings have
 important implications concerning applications of genetic monitoring in
 conservation planning for lake sturgeon and other species with similar
 life histories and mating systems.

 year01-10Adult data captured in
 10 years (2001-2010). Each year data include passive integrated
 transponder (PIT) tags, annual adult ID, sampling date, and genotypes
 based on 12 microsatelitte loci.2001offspringgenotypesData include ID and 12 microsatelitte loci genotypes of juveniles collected in 2001. BLJ1-, BLJ2-, and BLJ3- represent juveniles collected at Black Lake in the first, second and third runs, repsectively.2002offspringgenotypesData include ID (BLJ) and 12 microsatelitte loci genotypes of juveniles collected in 2002.2003offspringgenotypesData include ID and 12 microsatelitte loci genotypes of juveniles collected in 2003. IDs were marked as BLJ-, DF-, and DM-. BLJs represent juveniles that were collected during their drifting downstream at Upper Black Lake river, DF- and DM- live and dead juveniles that were collected and reared in a streamside hatchery for three months before being released to the river.2004offspringgenotypesData include ID and 12 microsatelitte loci genotypes of juveniles collected in 2004. IDs were marked as DF-, and DM- which represent live and dead juveniles, respecitively, which were collected and reared in a streamside hatchery for three months before being released to the river.2005offspringgenotypesData include ID and 12 microsatelitte loci genotypes of juveniles collected in 2005. IDs were marked as BDF-, BDM-, WDF-, and WDM-. DF and DM represent live and dead juveniles, respecitively, which were collected and reared in streamside hatcheries (B: Black Lake hatchery; W: Wolf Lake hatchery) for three months before being released to the river.2006offspringgenotypesData include ID and 12 microsatelitte loci genotypes of juveniles collected in 2006. IDs were marked as BDF-, BDM-, WDF-, WDM-, DF-, and DM-. DF and DM represent live and dead juveniles, respecitively. B and W represent streamside Black Lake and Wolf Lake hatcheries where juveniles were reared for three months before being released to the river. DF-, and DM- without B or D are live and dead juveniles that were collected during their drifting downstream at Upper Black Lake river.2007offspringgenotypesData include ID and 12 microsatelitte loci genotypes of juveniles collected in 2007. IDs were marked as DF-, and DM- which represent live and dead juveniles, respecitively, which were collected and reared in a streamside hatchery (Black Lake hatchery) for three months before being released to the river.
