Data from: Effective number of breeders, effective population size and their relationship with census size in an iteroparous species, Salvelinus fontinalis
Effective number of breeders, Nb, effective population size, Ne, iteroparity, small population size, brook trout, age at maturation Abstract: The relationship between the effective number of breeders (Nb) and the generational effective size (Ne) has rarely been examined empirically in species with overlapping generations and iteroparity. Based on a suite of 11 microsatellite markers we examine the relationship between Nb, Ne, and census population size (Nc) in 14 brook trout (Salvelinus fontanels) populations inhabiting 12 small streams in Nova Scotia and sampled at least twice between 2009 and 2015. Unbiased estimates of Nb obtained with individuals of a single cohort, adjusted on the basis of age at first maturation (α) and adult life span (AL) were from 1.66 to 0.24 times the average estimates of Ne obtained with random samples of individuals of mixed ages [i.e., N ̂(b(adj2))/〖mean(N ̂ (e(mixed ages)))]. In turn, these differences led to adjusted Ne estimates that were from nearly 5 to 0.7 times the estimates derived from mixed aged individuals. These differences translate into the same range of variation in the ratio of effective to census population size (N ̂_(e(adj2))N ̂_c) within populations. Adopting N ̂(e(adj2)) as the more precise and unbiased estimates, we found that these brook trout populations differ markedly in their effective to census population sizes (range ~0.3 to ~0.001). Using AgeNe we then show that the variance in reproductive success or reproductive skew varied among populations by a factor of 40 from a Vk/k≈5 to 200. These results suggest wide differences in population dynamics likely resulting from differences in productivity affecting the intensity of competition for access to mates or redds and thus, reproductive skew. Understanding the relationship between Ne, Nb and Nc and how these relate to population dynamics and fluctuations in population size are important for the design of robust conservation strategies in small populations with overlapping generations and iteroparity.

FIG. 5 in Phenotypic Variation in Brook Trout Salvelinus fontinalis (Mitchill) at Broad Spatial Scales Makes Morphology an Insufficient Basis for Taxonomic Reclassification of the Species
FIG. 5. Representative examples of diverse morphology, particularly in mouth shape and position, observed within a single stream-dwelling Brook Trout population. Fish on the first row display more inferior mouth positions, whereas fish on the last row show more isognathous and prognathic jaws with a terminal/superior mouth position. All fish were captured from Crabtree Creek in the Savage River Watershed of western Maryland (39827047.2500 N, 79812036.0800W). Fish total length is noted in the upper right corner of each photograph. A full description of collection and photography protocols is provided in Kazyak et al. (2015).
FIG. 3 in Phenotypic Variation in Brook Trout Salvelinus fontinalis (Mitchill) at Broad Spatial Scales Makes Morphology an Insufficient Basis for Taxonomic Reclassification of the Species
FIG. 3. Comparison of pored lateral-line scale counts for specimens collected from (A) 38 streams in the Great Smoky Mountains National Park (GSMNP) by Weathers et al. (2019) and (B) three streams surveyed by Stauffer (2020) and three populations described by Stauffer and King (2014) in Long Island, NY. Individual-level data collected by Weathers et al. (2019) are displayed with violin plots, with the width of the violin plot for each stream demonstrating the density of the distribution for a given value and the minimum and maximum values indicated by the tails of the distribution. Due to discrepancies between published and raw data, values from Stauffer (2020) and Stauffer and King (2014) are shown using two methods. Data from the publication appear as the mode(s) (circle) and range (lines), and the raw, individual-level data appear as violin plots. Streams appear on the x-axis by ascending average trait value, and streams included in both Weathers et al. (2019) and Stauffer (2020) are plotted with the same color (Cosby Creek [CS]: yellow; Greenbrier Creek [GB]: green; Indian Camp Creek [ICC]: blue). Data from populations in NY are shown in red and all other sites from GSMNP, TN in gray.
