“…The Yellowtail jack ( Seriola lalandi, Carangidae) has recently been recognized as three distinct species: one in the Northwest Pacific ( S. aureovittata ), another in the Northeast Pacific ( S. dorsalis ) and a third S. lalandi in the Southern Hemisphere (Martinez‐Takeshita et al . ). Molecular tools have prompted the recognition of distinct lineages even among large, well‐studied predators such as the Scalloped hammerhead shark ( Sphyrna lewini , Sphyrnidae) (Table ; Quattro et al .…”

Fishes that rule the world: circumtropical distributions revisited

et al. 2015

Briggs (1960) published the first checklist of circumtropical fishes with 107 species. This work served for a half century as the most comprehensive checklist of globally distributed fishes, but the intervening years witnessed many discoveries, and molecular data have changed the way we evaluate species. Here, we update the list guided by taxonomic revisions, phylogenies, phylogeographic data and DNA barcodes. The resulting list now includes 284 species. The dramatic increase is primarily due to two trends: (i) continued oceanic exploration leading to range revisions and species discoveries and (ii) public databases such as FishBase and the Catalogue of Fishes make range data more accessible. Five species were removed from the list as closer scrutiny revealed multiple taxa, 14 were removed due to updated range information, and 35 more are suspected to be species complexes. The species listed here are mostly pelagic and bathypelagic fishes. Euryhaline, anadromous, catadromous, freshwater, and with few exceptions, reef fishes do not achieve global distributions. The most species-rich family of marine fishes (Gobiidae) is absent. The fishes with the longest pelagic larval stage (Anguillidae) are absent. In contrast, requiem sharks (Carcharhinidae), tunas (Scombridae), jacks (Carangidae), remoras (Echeneidae) and especially lanternfishes (Myctophidae) have multiple representatives. The combined evidence indicates that high mobility as an adult is a key requirement to achieve a global distribution. Many others are members of monotypic genera or families, indicating old lineages that did not diversify. We conclude that global ranges may promote persistence over evolutionary timescales, but also reduce opportunities for speciation.

“…They are believed to be evenly distributed among major metazoan taxa and biogeographical regions (Pfenninger & Schwenk, 2007). The inability of researchers to distinguish between cryptic species poses serious problems with the estimation, protection, and management of biodiversity (Besansky, 1999;Liu, Möller, Gao, Zhang, & Li, 2011;Martinez-Takeshita et al, 2015) and may also lead to incorrect inferences in studies of species coexistence, speciation and biogeography (Chen, Zhong, Dai, Fan, & He, 2017;Hebert, Penton, Burns, Janzen, & Hallwachs, 2004;Razgour et al, 2011). In the last 2 decades, the increase of molecular phylogenetic studies has resulted in the discovery of unexpectedly high numbers of cryptic species complexes (Crespo & Lumbsch, 2010;Haine, Martin, & Cook, 2006;Janzen et al, 2017).…”

Patterns of differentiation in the life history and demography of four recently described species of the Brachionus calyciflorus cryptic species complex

et al. 2019

Brachionus calyciflorus is arguably the most studied freshwater monogonont rotifer. Although it has been recognised as a cryptic species complex for more than a decade, a formal (re‐)description of the four species known so far (B. calyciflorus, Brachionus dorcas, Brachionus elevatus, and Brachionus fernandoi) has only recently been made. Information on the ecology of these species is very scant and fragmented. The aim of this study was to test for ecological divergence between these four species, specifically their life history strategy and population demography. We conducted a life history experiment using 12–16 genotypes per species. For each species, genotypes were extracted from at least three different natural populations. In addition, we performed population‐level culture experiments with the aim to compare population growth rates and demographic structure of experimental populations among species. Finally, we searched the literature for life history studies with molecular data allowing retrospective species identification. We found pronounced differences in life history traits between B. fernandoi and the other three species. B. fernandoi had higher egg and juvenile development times and a lower egg production rate and mictic ratio. We detected no significant life history differences among B. calyciflorus, B. elevatus, and B. dorcas. Population growth rates of B. fernandoi and B. calyciflorus were higher than those of B. elevatus and B. dorcas. Life history divergence resulted in marked differences in the demographic structure of populations. Populations of B. fernandoi contained larger fractions of pre‐reproductive females and lower fractions of adult females with sexual eggs than populations of B. calyciflorus, B. elevatus, and B. dorcas. Mortality was found to be highest in B. elevatus and lowest in B. calyciflorus populations. Our results show that a reverse taxonomy approach is powerful in revealing sources of variation in ecologically relevant traits of cryptic species, such as life history and demographic structure. Explicit consideration of this variation is crucial for future studies of their dynamics in natural communities.

“…Our overall objectives were to 1) identify the range of taurine concentrations that influence the growth and survival rates of California yellowtail (CYT; S. dorsalis) during transition from live feeds to microparticulate diets and 2) determine the extent to which nutrient leaching from microparticulate diets affects these ranges. Based on results from Martinez-Takeshita et al (2015), CYT species name has changed from S. lalandi to S. dorsalis, and we will now refer to CYT as S. dorsalis.…”

Taurine is an important amino acid derivative for marine and freshwater fish, especially during early development. We investigated the range of taurine concentrations that influence the growth and survival rates of California yellowtail (CYT; Seriola dorsalis) during transition from live feeds to microparticulate diets, as well as the extent to which nutrient leaching from the microparticulate diets affects these ranges. We tested particle‐assisted rotationally agglomerated (PARA) particles with four levels of taurine: 4 (low taurine; LT), 45 (medium taurine; MT), 93 (high taurine; HT) and 122 g/kg (very high taurine; VHT). Our results showed that CYT postlarvae had no significant differences in growth, survival and feed consumption rates between the MT, HT and VHT treatments. However, it should be noted that the PARA particles containing 122 g/kg (VHT) taurine were especially prone to leaching and may have had taurine concentrations as low as 34.9 g/kg before they settled on the bottom of the tank. Therefore, the actual dietary taurine concentrations experienced by the larvae were likely lower than the initial dietary concentrations. More research is needed to evaluate the potential nutrient toxicity of elevated dietary taurine concentrations for marine fish larvae and juveniles.
