Conservation of Black Bass Diversity: An Emerging Management Paradigm

Black bass Micropterus spp. are quintessential North American sportfishes that support economically valuable fisheries and act as keystone predators within aquatic ecosystems. Despite their prominence among North American fish fauna, a number of taxonomic designations are unresolved and novel forms continue to be identified within drainages of the southeastern USA. We review the current understanding of black bass diversity, including distributions, evolutionary histories, and phylogenetic relationships. We also provide a brief overview of the major paradigms that have been applied to black bass management and highlight an emerging focus on the conservation of black bass diversity. Black bass diversity is threatened by anthropogenic land and water use, fragmentation of fluvial habitats, historic and contemporary stocking of non‐native congeners, and climate change. Successful conservation of black bass diversity requires that management agencies prioritize the protection of native species, forms, and lineages within and across jurisdictional boundaries. Collaboration among scientists and resource managers is needed to develop practical ways to ameliorate current problems created by past and present anthropogenic alterations, while also preparing for future challenges like global climate change.

“…Most tips were assigned a value of one, although our tree contained 32 of the 38 currently known centrarchid species. We collapsed Micropterus coosae into a total of five species (Baker et al 2013), and both Micropterus punctulatus and Lepomis megalotis into two species (Baker et al 2008;Warren 2009). MEDUSA starts by fitting a birth-death, two-parameter model to the tree.…”

Body Shape Evolution in Sunfishes: Divergent Paths to Accelerated Rates of Speciation in the Centrarchidae

et al. 2015

Vertebrate evolutionary radiations are the result of divergence along a variety of ecological and behavioural axes. In addition, the potential for clades to evolve along any one axis can be strongly influenced by the types and levels of phenotypic variation that are exposed to natural selection. Understanding the factors that promote and constrain morphological diversification is a central goal of evolutionary biology. Here we use the sunfishes (Centrarchidae), a perciform family containing three main clades (Lepomis, Micropterus, and a basal clade), to explore this question with respect to variation in body shape. We gathered morphological data from 26 of the 38 centrarchid species using geometric morphometrics and analyzed the resultant shape data over a time-calibrated phylogenetic tree. We find that centrarchids partitioned body shape early in their evolutionary history, a pattern that is largely associated with expansion into divergent foraging niches and elaboration of sexual ornamentation. The morphological disparity of each clade was tightly linked to integration: those clades with high disparity (Lepomis, basal clade) were the least integrated, while the opposite trend was observed in Micropterus. We also find evidence for an increase in speciation rate at the node leading to Lepomis and Micropterus, and a decline in speciation for the basal clade. Our data lead us to suggest different hypotheses for explaining accelerated speciation in Micropterus and Lepomis: invasion of a novel pursuitpredator niche that reduced resource competition (Micropterus), and the elaboration of opercular morphology (Lepomis), a trait that is linked to reproductive behaviour and facilitates mate recognition in communities with many sunfish species.

Genetic diversity and divergence patterns of smallmouth bass Micropterus dolomieu spawning groups are analysed across its northern native range with mtDNA cytochrome b gene sequences and eight unlinked nuclear DNA microsatellite loci. Results reveal high levels of genetic variability and significant differences in allelic representation among populations (mtDNA: mean ± s.e., H = 0·50 ± 0·06, mean ± s.e., θ = 0·41 ± 0·02 and microsatellites: mean ± s.e. H = 0·46 ± 0·03, mean ± s.e. θ = 0·25 ± 0·01). The distributions of 28 variant mtDNA haplotypes, which differ by an average of 3·94 nucleotides (range = 1-8), denote divergent representation among geographic areas. Microsatellite data support nine primary population groups, whose high self-assignment probabilities likewise display marked divergence. Genetic patterns demonstrate: (1) high genetic diversity in both genomes, (2) significant divergence among populations, probably resulting from natal site homing and low lifetime migration, (3) support for three post-glacial refugia that variously contributed to the current northern populations, which remain evident today despite waterway connectivity and (4) a weak yet significant genetic isolation by geographic distance pattern, indicating that other processes affect the differences among populations, such as territoriality and site fidelity.
