A Review of River Herring Science in Support of Species Conservation and Ecosystem Restoration

River herring—a collective name for the Alewife Alosa pseudoharengus and Blueback Herring A. aestivalis—play a crucial role in freshwater and marine ecosystems along the Eastern Seaboard of North America. River herring are anadromous and return to freshwater habitats in the tens to hundreds of millions to spawn, supplying food to many species and providing nutrients to freshwater ecosystems. After two and a half centuries of habitat loss, habitat degradation, and overfishing, river herring are at historic lows. In 2013, National Oceanic and Atmospheric Administration Fisheries established the Technical Expert Working Group (TEWG) to synthesize information about river herring and to provide recommendations to advance the science related to their restoration. This paper was composed largely by the chairs of the TEWG subgroups and represents a review of the current state of knowledge of river herring, with an emphasis on identification of threats and discussion of recent research and management actions related to understanding and reducing these threats. Important research needs are then identified and discussed. Finally, current knowledge is synthesized, considering the relative importance of different threats. This synthesis identifies dam removal and increased stream connectivity as critical to river herring restoration. Better understanding and accounting for predation, climate change, and fisheries are also important for restoration. Finally, there is recent evidence that the effects of human development and contamination on habitat quality may be more important threats than previously recognized. Given the range of threats, an ecosystem approach is needed to be successful with river herring restoration. To facilitate this ecosystem approach, collaborative forums such as the TEWG (renamed the Atlantic Coast River Herring Collaborative Forum in 2020) are needed to share and synthesize information among river herring managers, researchers, and community groups from across the species’ range.

“…Hybridization is in C. viridis is unsurprising as closely related Pomacentrids often have overlapping geographic distributions, co-occur in the same microhabitats (e.g., colonies of branching corals) (Randall & Allen, 1977). Hybridization has been observed in several sibling species of damselfish, including Abudefduf abdominalis × Abudefduf vaigiensis (Coleman et al, 2014), Amphiprion chrysopterus × Amphiprion sandaracinos (Gainsford, Van Herwerden & Jones, 2015), Amphiprion mccullochi × Amphiprion akindynos (Van Der Meer et al, 2012), Dascyllus carneus × D. marginatus (DiBattista et al, 2015), and D. reticulatus × D. aruanus (He et al, 2017). As such, both hybridization and incomplete lineage sorting are likely responsible for the discordant patterns in the two markers.…”

Species delimitation is challenging in sibling species/cryptic lineages because of the absence of clear diagnostic traits. However, integration of different approaches such as phylogeography and ecological niche comparison offers one potential approach to tease apart recently diverged lineages. In this study, we estimate the ecological niche divergence among lineages in Chromis viridis in a broad-scale phylogeographic framework to test whether the combination of these two approaches can effectively distinguish recently diverged lineages. Results from Cytb and Rag2 analyses identified two cryptic lineages (C. viridis A and C. viridis B) that diverged ∼3 Myr ago. Estimates of ecological niche divergence with 11 environmental parameters across the broad geographic range of these lineages showed overlapping ecological niches and niche conservatism. However, regardless of the incongruence between genetic and ecological niche divergence, the substantial genetic divergence between the two clades of C. viridis in both mtDNA and nuclear loci strong suggest that they are cryptic taxa.

“…The nuclear gene RAG1 was chosen because it is widely used in fish systematics, including several studies of pomacentrids (e.g., Quenouille et al, 2004;Cooper et al, 2009;Frédérich et al, 2013;Lobato et al, 2014;Souza et al, 2016;Bertrand et al, 2017;Delrieu-Trottin et al, 2019). Tmo-4C4 has been used sparingly to investigate damselfishes (Allen et al, 2012a;DiBattista et al, 2015;He et al, 2018He et al, , 2019a, but it has proven to be phylogenetically informative for putative close relatives of Pomacentridae (e.g., Streelman and Karl, 1997;Streelman et al, 1998;Farias et al, 2000;Sparks and Smith, 2004;Chakrabarty, 2006;Smith et al, 2008;McMahan et al, 2013;Xia et al, 2016).…”

The family Pomacentridae is a species-rich group of primarily marine fishes. The phylogenetic relationships of the damselfishes are examined herein using sequence data from five mitochondrial (12S, 16S, ATP synthase subunits 8/6, cytochrome b, and cytochrome c oxidase I) and three nuclear (histone H3, recombination activating gene 1 exon 3, and Tmo-4C4) loci. A combined data matrix of 6,865 base pairs was compiled for 462 taxa, representing 322 damselfish species, and used to reconstruct the phylogeny of pomacentrids via maximum likelihood. The resulting topology supports the monophyly of the family and some groups within it, corroborating some conclusions drawn by recent studies but contradicting others. We find that the family is composed of four major lineages, recognized herein as the subfamilies Chrominae, Glyphisodontinae, Microspathodontinae, and Pomacentrinae. The subfamily Microspathodontinae is sister to a clade of the other three subfamilies, and the subfamily Glyphisodontinae is sister to a clade of Chrominae and Pomacentrinae. The monotypic subfamily Lepidozyginae is recovered within Microspathodontinae and placed in the synonymy of Microspathodontinae. Species of Plectroglyphidodon and Stegastes are reassigned to maintain the monophyly of both genera. In Chrominae, the generic limits of Azurina and Chromis are revised to reflect monophyletic groups. The genus-group name Pycnochromis is resurrected to accommodate a group of former Chromis sister to Dascyllus. In Pomacentrinae, the genus Premnas is recovered within Amphiprion and placed in the synonymy of Amphiprion. The genus Chrysiptera is broadly polyphyletic within Pomacentrinae. The genus Amblypomacentrus is revised to accommodate some species formerly classified as Chrysiptera.
