OLDFIELD1,2, ABHINAV KAKUTURU1, WILLIAM I. LUTTERSCHMIDT2, O. TOM LORENZ3, ADAM E. COHEN4, AND DEAN A. HENDRICKSON4 ABSTRACT The Rio Grande Cichlid, Herichthys cyanoguttatus, is native to the drainages of the Gulf Coast of northern Mexico and southern Texas and has been introduced at several sites in the US. Previous observations have suggested that non-native populations in Louisiana that are currently recognized as H. cyanoguttatus resemble another species, the Lowland Cichlid, H. carpintis. Traditional morphological and genetic techniques have been insufficient to differentiate these species, but H. carpintis has been reported to differ fromH. cyanoguttatus in color pattern, so we turned to novel electronic photo archives to determine the identity of the species introduced in Louisiana. First, we used the public databases Nonindigenous Aquatic Species Database and Fishes of Texas to infer the historical distributions of these species in the US. -

A genetic and morphometric study of populations of Zoogoneticus quitzeoensis (Bean, 1898) from the Lerma and Ameca basins and Cuitzeo, Zacapu and Chapala Lakes in Central Mexico was conducted. For the genetic analysis, 7 populations were sampled and 2 monophyletic groups were identifi ed with a genetic difference of DHKY= 3.4% (3-3.8%), one being the populations from the lower Lerma basin, Ameca and Chapala Lake, and the other populations from Zacapu and Cuitzeo Lakes. For the morphometric analysis, 4 populations were sampled and 2 morphotypes identifi ed, 1 from La Luz Spring in the lower Lerma basin and the other from Zacapu and Cuitzeo Lakes drainages. Using these 2 sources of evidence, the population from La Luz is regarded as a new species Zoogoneticus purhepechus sp. nov. _The new species differs from its sister species Zoogoneticus quitzeoensis_ in having a shorter preorbital distance (Prol/SL x = 0.056, SD = 0.01), longer dorsal fi n base length (DFL/SL x = 0.18, SD = 0.03) and 13-14 rays in the dorsal fi n. -
The Evolution of the Placenta Drives a Shift in Sexual Selection in Livebearing Fish
LETTER doi:10.1038/nature13451 The evolution of the placenta drives a shift in sexual selection in livebearing fish B. J. A. Pollux1,2, R. W. Meredith1,3, M. S. Springer1, T. Garland1 & D. N. Reznick1 The evolution of the placenta from a non-placental ancestor causes a species produce large, ‘costly’ (that is, fully provisioned) eggs5,6, gaining shift of maternal investment from pre- to post-fertilization, creating most reproductive benefits by carefully selecting suitable mates based a venue for parent–offspring conflicts during pregnancy1–4.

These females, however, run the risk of mat- predicts that the rise of these conflicts should drive a shift from a ing with genetically inferior (for example, closely related or dishonestly reliance on pre-copulatory female mate choice to polyandry in conjunc- signalling) males, because genetically incompatible males are generally tion with post-zygotic mechanisms of sexual selection2.

Here we apply comparative these risks by producing tiny, inexpensive eggs and creating large mixed- methods to test a key prediction of this hypothesis, which is that the paternity litters by mating with multiple males.

Accepted 31-VII-2008. Abstract: the structural and ultrastructural features of gonads from endemic Mexican fish have received scarce attention. This study describes the histological and ultrastructural characteristics of the oocyte in Chirostoma humboldtianum. The ovary is asynchronic, and as such, most phases of oocyte development are found in the same ovary. The complete process of oogenesis was divided in five stages: oogonium and folliculogenesis, pri- mary growth, cortical alveoli and lipid inclusions, vitellogenesis and maturation. The presence of big filaments, which appear at the end of primary growth, induces some common follicular adaptation. During primary growth, abundant ribosomes, rough endoplasmic reticulum, and mitochondria are grouped in the cytoplasm. At the end of this stage, the Z1 layer of the chorion is developed, while microvilli start to be evident as well. In the corti- cal alveoli and lipid droplets phase, intense PAS positive vesicles, some of them containing nucleoid material, are observed in the peripheral cytoplasm and the lipid droplets take a more central position. In vitellogenesis, the proteic yolk accumulates in a centripetal way while the chorion is completely formed. -

(January 2018). 1 1 Native Range and Status in the United States Native Range From Fuller (2018): “This species is confined to a very small area, the Río Ameca basin, on the Pacific Slope of western Mexico (Miller and Fitzsimons 1971).” From Goodeid Working Group (2018): “This species comes from the Pacific Slope and inhabits the Río Ameca and its tributary, the Río Teuchitlán in Jalisco. More habitats in the ichthyological [sic] closely connected Sayula valley have been detected quite recently.” Status in the United States From Fuller (2018): “Reported from Nevada. Records are more than 25 years old and the current status is not known to us. One individual was taken in November 1981 (museum specimen) and another in August 1983 from Rodgers Spring, Nevada (Courtenay and Deacon 1983, Deacon and Williams 1984). Others were seen and not collected (Courtenay, personal communication).” From Goodeid Working Group (2018): “Miller reported, that on 6 May 1982, this species was collected in Roger's Spring, Clark County, Nevada, (pers. comm. to Miller by P.J. Unmack) where it is now extirpated. It had been exposed there with several other exotic species (Deacon [and Williams] 1984).” From FAO (2018): “Status of the introduced species in the wild: Probably not established.” From Froese and Pauly (2018): “Raised commercially in Florida, U.S.A.” Means of Introductions in the United States From Fuller (2018): “Probably an aquarium release.” Remarks From Fuller (2018): “Synonyms and Other Names: butterfly goodeid.” 2 From Goodeid Working Group (2018): “Some hybridisation attempts have been undertaken with the Butterfly Splitfin to solve its relationship. -

Endangered Species
FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.

Temporal Diversification of Mesoamerican Cichlid Fishes Across

Neara,1 a Center for Population Biology, Department of Evolution and Ecology, University of California-Davis, Davis, CA 95616, USA b Laboratorio de Biologıa Integrativa, Instituto Tecnologico de Cuidad Victoria (ITCV), Mexico c Section of Integrative Biology, University of Texas-Austin, Austin, TX 78712, USA Received 18 June 2003; revised 26 August 2003 Abstract The Mexican Neovolcanic Plateau sharply divides the vertebrate fauna of Mesoamerica where the climate of both the neotropics and temperate North America gradually blend. Only a few vertebrate groups such as the Heroine cichlids, distributed from South America to the Rio Grande in North America, are found both north and south of the Neovolcanic Plateau. To better understand the geography and temporal diversification of cichlids at this geologic boundary, we used mitochondrial DNA sequences of the cy- tochrome b (cyt b) gene to reconstruct the relationships of 52 of the approximately 80 species of Heroine cichlids in Mesoamerica. Our analysis suggests several cichlids in South America should be considered as part of the Mesoamerican Heroine clade because they and the cichlids north of the Isthmus of Panama are clearly supported as monophyletic with respect to all other Neotropical cichlids. We also recovered a group containing species in Paratheraps + Paraneetroplus + Vieja as the sister clade to Herichthys. Herichthys is the only cichlid clade north of the Mexican Plateau and it is monophyletic. -
