Abstract

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change. There are no copyright restrictions on the data, and please cite this data paper when using the data in publications.

Abstract

Introduction Ribosomal genes, which constitute one of the major multigene families, are studied extensively in fish. These genes can characterize groups being located in one chromosome pair as in the [...], The genus Astyanax is widely distributed from the southern United States to northern Patagonia, Argentina. While cytogenetic studies have been performed for this genus, little is known about the histone gene families. The aim of this study was to examine the chromosomal relationships among the different species ofAstyanax. The chromosomal locations of the 5S rRNA and H3 histone genes were determined in A. abramis, A asuncionensis, A altiparanae, A bockmanni, A eigenmanniorum, A mexicanus (all 2n = 50), Afasciatus (2n = 46), and A schubarti (2n = 36). All eight species exhibited H3 histone clusters on two chromosome pairs. In six species (A. abramis, A. asuncionensis, A altiparanae, A bockmanni, A eigenmanniorum, and Afasciatus), syntenic clusters of H3 histone and 5S rDNA were observed on metacentric (m) or submetacentric (sm) chromosomes. In seven species, clusters of 5S rDNA sequences were located on one or two chromosome pairs. In A mexicanus, 5S rDNA clusters were located on four chromosome pairs. This study demonstrates that H3 histone clusters are conserved on two chromosome pairs in the genus Astyanax, and specific chromosomal features may contribute to the genomic organization of the H3 histone and 5S rRNA genes. Keywords: repetitive DNAs, karyotype evolution, FISH, Mexican blind cavefish, Astyanax schubarti. Le genre Astyanax presente une large aire de distribution allant du sud des Etats-Unis au nord de la Patagonie en Argentine. Bien que des etudes cytogenetiques aient ete realisees chez ce genre, peu de choses sont connues au sujet des familles de genes codant pour les histones. Le but de cette etude etait d'examiner les relations chromosomiques au sein des differentes especes d'Astyanax. Les positions chromosomiques des genes codant pour les ARNr 5S et les histones H3 ont ete determinees chez A abramis, A asuncionensis, A altiparanae, A bockmanni, A eigenmanniorum, A mexicanus (toutes a 2n = 50), A fasciatus (2n = 46) et A schubarti (2n = 36). Chez les huit especes, les genes d'histones H3 etaient groupes sur deux paires de chromosomes. Chez six especes (A abramis, A. asuncionensis, A. altiparanae, A. bockmanni, A eigenmanniorum, et A. fasciatus), les amas de genes codant pour les histones H3 et l'ADNr 5S ont ete observes sur des chromosomes metacentriques (m) ou submetacentriques (sm). Chez sept especes, les amas de sequences d'ADNr 5S etaient situes sur une ou deux paires de chromosomes. Chez l'A mexicanus, les ADNr 5S etaient repartis sur quatre paires de chromosomes. Cette etude montre que les amas de genes codant pour les histones H3 sont conserves sur deux paires de chromosomes au sein du genre Astyanax et que des caracteristiques chromosomiques specifiques pourraient contribuer a l'organisation genomique des genes codant pour les histones H3 et les ARNr 5S.

Abstract

Made available in DSpace on 2018-12-11T17:24:12Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-06-08 The W chromosome of Megaleporinus trifasciatus was isolated in order to analyze its behavior in the karyotype of this and other species of the family, including forms with differentiated and undifferentiated sex chromosomes. The chromosome was microdissected, and the WMt probe was prepared for the chromosome painting procedure. M. trifasciatus was also cross-hybridized (cross-FISH) using existing probes available for M. macrocephalus (WMm) and M. elongatus (WMe). Two Leporinus species and Semaprochilodus taeniurus, representing a clade close to the Anostomidae, were also cross-hybridized with the objective to better understand the evolution of the sex chromosomes. In the metaphase of female M. trifasciatus, the WMt probe highlighted the whole long arm of the W chromosome and a small, distal portion of the long arm of the Z chromosome. In males, the probe highlighted the distal portion of the long arm of the Z chromosomes. The hybridization of female M. trifasciatus with the WMe and WMm probes revealed a pattern similar to that encountered using the WMt probe. The WMt, WMm, and WMe probes revealed broad similarities among the species of the genus Megaleporinus, which has a ZZ/ZW system of sex chromosomes, with only minor alterations becoming apparent when analyzed separately. aInstituto Nacional de Pesquisas da Amazônia (INPA), Programa de Pós-graduação em Genetica, Conservação e Biologia Evolutiva, Petrópolis, Manaus, and bInstituto de Biociências, Universidade Estadual Paulista “Júlio de Mesquita Filho” (UNESP), Campus de Rio Claro, Rio Claro, Brazil

Here, the chromosomal organizations of (CA)15, (GA)15, (CG)15, (GACA)4, and (GATA)8 microsatellites were examined in several Astyanax species with different diploid numbers: Astyanax mexicanus (2n = 50 + 1 B chromosome), A. altiparanae (2n = 50), A. marionae (2n = 48), A. fasciatus (2n = 46), and A. schubarti (2n = 36). The (CA)15 and (GA)15 microsatellites were dispersed across the chromosomes of A. altiparanae and A. fasciatus but were also observed as clusters (CA and GA for A. altiparanae, and CA for A. fasciatus). In A. marionae and A. schubarti, the (CA)15 and (GA)15 microsatellites were dispersed but were also observed as clustered signals and coincident with heterochromatic regions. In all 4 of these species, the (CG)15 and (GACA)4 microsatellites were dispersed across chromosomes, and the (GATA)8 microsatellite was co-localized with 5S rDNA. In A. mexicanus, the (CA)15, (GA)15, (CG)15, (GATA)8, and (GACA)4 microsatellites were weakly detected and dispersed across the chromosomes of the A complement. On the B chromosome, signals for the different microsatellites were weak, strong, absent, weak, and absent, respectively. The distribution of microsatellites and the locational relationship between microsatellites and 5S rDNA are discussed, and a possible evolutionary pathway is proposed for microsatellites in Astyanax.

Atualmente, são descritas aproximadamente 150 espécies no gênero, e este se distribui sobre a região Neotropical com ocorrências desde o sul dos Estados Unidos até a região da Patagônica na Argentina. Dentro da região de ocorrência o gênero apresenta espécies com 2n = 36 cromossomos apenas para Astyanax schubarti e Astyanax correntinus, 2n = 46 para, por exemplo, Astyanax fasciatus, 2n = 48 para Astyanax marionae, 2n = 50 para Astyanax altiparanae, e 2n = 52 para Astyanax sp. Visto que o grupo apresenta variações significantes no número diploide, este trabalho teve como principal objetivo estudar o mapeamento cromossômico de DNAs repetitivos numa abordagem evolutiva. Nove espécies de Astyanax foram analisadas: A. altiparanae e A. schubarti provenientes da bacia do rio Piracicaba (SP), A. abramis, A. asuncionensis e A. marionae provenientes da bacia do rio Paraguai (MT), A. bockmanni proveniente da bacia do rio Iguatemi (MS), A. eigenmanniorum e A. mexicanus provenientes de loja de aquário, e diferentes populações de A. fasciatus provenientes da bacia do rio Corumbataí (SP). Para tanto, foram mapeados os genes de RNAr (18S e 5S), histona H3, RNAsn U2, microssatélites e DNA telomérico. Ainda, foram realizados estudos envolvendo técnicas clássicas de citogenética (Ag-NOR, banda-C e coloração com CMA3/DAPI) e estudos do relógio molecular utilizando o gene mitocondrial citocromo c oxidase subunidade I (COI). São discutidos, ainda, parâmetros da evolução cromossômica e hipóteses sobre eventos particulares (cromossômicos e evolutivos) no grupo Astyanax. The genus Astyanax is currently seen as a group with phylogenetic confusion, setting up to date as polyphyletic within the family Characidae. Currently, there are about 150 described species in the genus, and this is distributed on the Neotropical region from the southern United States to the region of Patagonia in Argentina. Within the region of occurrence of the genus shows species with 2n = 36 chromosomes only Astyanax schubarti and Astyanax correntinus, 2n = 46, for example, to Astyanax fasciatus, 2n = 48 to Astyanax marionae, 2n = 50 to Astyanax altiparanae, and 2n = 52 to Astyanax sp. Since the group presents significant variations in the diploid number, this work focused primarily on the study of chromosomal mapping of repetitive DNAs with an evolutionary approach. Nine species of Astyanax were examined: A. altiparanae and A. schubarti from the Piracicaba River basin (SP), A. abramis, A. asuncionensis and A. marionae from the Paraguay River basin (MT), A. bockmanni from the Iguatemi River basin (MS), A. eigenmanniorum and A. mexicanus from the aquarium store, and A. fasciatus from the Corumbataí River basin (SP). Therefore, the genes mapped were rRNA (18S and 5S), histone H3, U2 snRNA, microsatellites and telomeric DNA. Further, studies were conducted involving classical cytogenetic techniques (Ag-NOR, C-band and staining with CMA3/DAPI) and the molecular clock using the mitochondrial gene cytochrome c oxidase subunit I (COI). Are also discussed, parameters of chromosomal evolution and hypothesis about particular events (chromosomal and evolutionary) in the group Astyanax.

A subfamília Tetragonopterinae, antes considerada como a subfamília com o maior número de espécies foi considerada como um grupo polifilético. A partir de então, somente o gênero Tetragonopterus foi mantido na subfamília e todos os demais gêneros de Tetragonopterinae foram alocados em incertae sedis dentro de Characidae. Muitos exemplares pertencentes a este grupo, já tiveram seus cromossomos estudados, demonstrando que o número diploide mais frequente é 2n=50/2n=52 cromossomos. Outra característica marcante compartilhada por muitas espécies da família é o primeiro par metacêntrico maior do que os demais cromossomos do complemento A. Diante das problemáticas taxonômicas apresentadas na literatura para o grupo incertae sedis e considerando que ainda há muito que ser estudado sobre a citogenética dos mesmos, o presente trabalho constituiu em realizar análises dos cromossomos de espécies dos gêneros Bryconamericus, Piabina, Hyphessobrycon e Astyanax, visando detectar possíveis variações que permitam um melhor entendimento das relações evolutivas entre as populações desses gêneros em incertae sedis. Para tanto, os cromossomos das espécies Bryconamericus stramineus da bacia do rio Iguatemi - MS; Bryconamericus turiuba, Bryconamericus cf. iheringii, Piabina argentea, Hyphessobrycon eques e três populações de Astyanax fasciatus provenientes da bacia do rio Corumbataí - SP; Astyanax abramis do córrego Bento Gomes (MT); Astyanax mexicanus e Astyanax eigenmanniorum provenientes de loja de aquário e duas populações de Astyanax altiparanae provenientes do ICMBio- CEPTA - Pirassununga (SP) e córrego Guaçu... Among the Characiformes, the Characidae family is the largest group of the order involving large and small fish. The subfamily Tetragonopterinae, previoulsy considered as the subfamily with the greatest number of species was considered as a polyphyletic group. Since then, only the genus Tetragonopterus was kept in the subfamily and all other Tetragonopterinae species were considered as incertae sedis within Characidae. Many specimens belonging this group had been their chromosomes studied, demonstrating that the most frequent diploid number is 2n=50/52 chromosomes. Another striking feature shared by many species of the family is the first metacentric pair larger than the other chromosomes of the complement A. Given the taxonomic problems presented in the literature for the group incertae sedis and considering that much remains to be studied about the cytogenetics of these group, the present work was to perform analysis of chromosomes of the genus Bryconamericus, Piabina, Astyanax and Hyphessobrycon, to detect possible variations that allow a better understanding of evolutionary relationships among populations in these genus in incertae sedis. The chromosomes of Bryconamericus stramineus Iguatemi River basin - MS; Bryconamericus turiuba, Bryconamericus cf. iheringii, Piabina argentea, Hyphessobrycon eques and tree populations of Astyanax fasciatus from Corumbataí River basin – SP; Astyanax abramis from stream Bento Gomes (MT); Astyanax mexicanus and Astyanax eigenmanniorum from aquarium store and two populations of Astyanax altiparanae from the ICMBio-CEPTA - Pirassununga (SP ) and stream Guaçu (MS) were analyzed using classical techniques such as Giemsa staining, Ag-RON, Cband and CMA3 addition to applying the technique of fluorescence in situ hybridization (FISH) with 18S and...

Abstract

AbstractAstyanaxis a genus with a wide distribution ranging from the south United States to north of Patagonia (Argentina). The available cytogenetic data on Astyanaxindicate a high karyotypic diversity, with diploid number of 36–52 chromosomes, presence of B chromosomes, heterochromatin polymorphism, and variations with respect to the number and localization of nucleolar organizer regions (NORs) and 18S and 5S ribosomal DNA sites. In the present study, we estimated the evolutionary history and times of divergence for 10 nominal Astyanaxspecies from the South and Central/North American (Cna) continents, which present distinct chromosomal characteristics, based on molecular clocks inferred from mitochondrial DNA sequence. The molecular clock results indicate the origin of three distinct clades (Humeral dark spot [Hds]; Diffuse humeral spot [Dhs]; Cna group) during the late Miocene about 11.2 million years ago (Mya). Thus, Astyanax mexicanus(Cna) represent a species that diverged a long time ago (∼8.6 Mya) from the Hds group, and Astyanax schubartiis the oldest species (∼6.5 Mya) among the Dhs species.

Abstract

AbstractThe cytogenetic studies of retrotranposons Rexhave been characterized in several fish groups, including species of the Astyanaxgenus. This group presents an extensive variability in their karyotype, with diploid numbers of 2n =52, 50, 48, 46 and 36 chromosomes. Thus, the aim of this study was to evaluate the distribution of the retrotransposable element Rex1, in six Astyanaxspecies, with different diploid numbers. The species analyzed were Astyanax altiparanae(2n =50), Astyanax asuncionensis(2n =50), Astyanax eigenmanniorum(2n =50), Astyanax marionae(2n =48), Astyanax fasciatus(2n =46) and Astyanax schubarti(2n =36). Rex1 was dispersed in the Astyanaxspecies, suggesting that these retrotransposons play important role in genome evolution.

Abstract

AbstractRepetitive sequences and their chromosomal locations have been widely studied in species of the Astyanaxgenus. However, the chromosomal organization of U2 snDNA remains largely unknown. The aims of this study were to examine the chromosomal contexts of U2 snRNA and 5S rRNA genes in Astyanaxspecies and determine the degree of chromosome morphological similarity between species with different diploid numbers. Clusters of U2 snDNA and 5S rDNA were determined in nine species of Astyanax, including two karyomorphs of Astyanax fasciatusCuvier, 1819. All species exhibited U2 snDNA clusters on two chromosome pairs, except Astyanax mexicanusDe Filippi, 1853 (one pair). The 5S rDNA clusters were located on one chromosome pair in Astyanax altiparanaeGarutti and Britski, 2000, and Astyanax marionaeEigenmann, 1911, two pairs in Astyanax abramisJenyns, 1842, Astyanax asuncionensisGéry, 1972, Astyanax bockmanniVari and Castro, 2007, Astyanax eigenmanniorumCope, 1894, A. fasciatus(karyomorphs I and II), and Astyanax schubartiBritski, 1964, and four pairs in A. mexicanus. The relationships between the repetitive sequences in different species suggest that A. schubartiand A. mexicanusexhibit an unusual U2 snDNA chromosomal format as a result of events occurring in the evolutionary history of the Astyanaxgroup.

Abstract

AbstractThe species of genus Astyanaxis widely distributed in freshwater neotropical zones. Astyanaxis considered to be taxonomically confused, similar to other genera placed incertae sedisin Characidae. The cytogenetics of this genus is well characterized; species vary widely in diploid number, from 2n=36 chromosomes in Astyanax schubartito 2n=50 for most species studied. The size, number, and position of different cytological markers vary among species and populations of Astyanax. We analyzed the karyotypes of individuals from three Astyanaxspecies (Astyanax abramis, Astyanax altiparanae, and Astyanax eigenmanniorum) from populations not previously analyzed. We describe variations in several cytogenetic markers and the karyotypic relationships between them, specifically focusing on the characteristics of the conserved and divergent locations of the ribosomal genes. Our data are useful for establishing relationships between species and for investigating the karyotype evolution within the genus.

Abstract

Farlowellais the second richest genus in Loricariinae, broadly distributed in freshwater streams and rivers of South America. In this article, we aimed to expand on the cytogenetic and molecular data available for two allopatric populations of Farlowella hahni. Both populations had diploid chromosome number 58, but with karyotype differences, indicative of chromosomal rearrangements. C-banding showed large heterochromatic blocks at telomeric regions in acrocentric chromosomes in both populations. Fluorescence in situhybridization (FISH) revealed a single 18S rDNA site in both populations and a single 5S rDNA site for individuals from lower Paraná River basin (native region) and multiple 5S rDNA sites for individuals from upper Paraná River basin (non-native region). Mitochondrial sequence analyses did not separate the two F. hahnipopulations. The cytogenetic and molecular data obtained are relevant in a preliminary study and suggested the existence of cryptic diversity and the hypothesis that at least two Farlowellalineages may coexist in the Paraná basin.

Abstract

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change. There are no copyright restrictions on the data, and please cite this data paper when using the data in publications., (© 2022 The Ecological Society of America.)

Abstract

The Hyphessobrycon are allocated in the incertae sedis group of the Characidae family, one of the genera with more species of the group. The chromosomes of some species of Hyphessobrycon are known, and the diploid number most common for genus is 2n = 50 chromosomes. The aims of this study were to examine the karyotype macrostructure in the Hyphessobryconeques Steindachner, 1882, and show a new origin hypothesis for B chromosomes. The diploid number observed for Hyphessobryconeques was 2n = 52 chromosomes, and a karyotype formulae of 12m + 18sm + 8st + 14a, with FN (fundamental number) = 90 for both sexes. Only two females showed one B chromosome. The heterochromatin was observed mainly on centromeric regions, and in the long arm of the B chromosome. In this paper, the relationship of the B chromosome of Hyphessobryconeques with an occasional chromosome rearrangement was discussed.
