Design & Layout by: Tasamim Design - www.tasamim.net Printed by: The Colchester Print Group, United Kingdom Picture credits on cover page: The European Mudminnow (Umbra krameri) is a European endemic found in the Danube and Dniestr basin. Its population has declined by more than 30% in the past 10 years due to river regulation and drainage of wetlands for agriculture which resulted in a reduced number of backwaters. This species is therefore classed as Vulnerable. Photograph © Andreas Hartl.

  • Mito-Nuclear Sequencing Is Paramount to Correctly Identify Sympatric Hybridizing Fishes
    ACTA ICHTHYOLOGICA ET PISCATORIA (2018) 48 (2): 123–141 DOI: 10.3750/AIEP/02348 MITO-NUCLEAR SEQUENCING IS PARAMOUNT TO CORRECTLY IDENTIFY SYMPATRIC HYBRIDIZING FISHES Carla SOUSA-SANTOS1*, Ana M.

Mito-nuclear sequencing is paramount to correctly identify sympatric hybridizing fishes. Acta Ichthyol. Piscat. 48 (2): 123–141. Background. Hybridization may drive speciation and erode species, especially when intrageneric sympatric species are involved. Five sympatric Luciobarbus species—Luciobarbus sclateri (Günther, 1868), Luciobarbus comizo (Steindachner, 1864), Luciobarbus microcephalus (Almaça, 1967), Luciobarbus guiraonis (Steindachner, 1866), and Luciobarbus steindachneri (Almaça, 1967)—are commonly identified in field surveys by diagnostic morphological characters. Assuming that i) in loco identification is subjective and observer-dependent, ii) there is previous evidence of interspecific hybridization, and iii) the technical reports usually do not include molecular analyses, our main goal was to assess the concordance between in loco species identification based on phenotypic characters with identifications based on morphometric indices, mtDNA only, and a combination of mito-nuclear markers.

  • Phylogenetic Relationships of Freshwater Fishes of the Genus Capoeta (Actinopterygii, Cyprinidae) in Iran
    Received: 3 May 2016 | Revised: 8 August 2016 | Accepted: 9 August 2016 DOI: 10.1002/ece3.2411 ORIGINAL RESEARCH Phylogenetic relationships of freshwater fishes of the genus Capoeta (Actinopterygii, Cyprinidae) in Iran Hamid Reza Ghanavi | Elena G. Gonzalez | Ignacio Doadrio Museo Nacional de Ciencias Naturales, Biodiversity and Evolutionary Abstract Biology Department, CSIC, Madrid, Spain The Middle East contains a great diversity of Capoeta species, but their taxonomy re- Correspondence mains poorly described. We used mitochondrial history to examine diversity of the Hamid Reza Ghanavi, Department of algae- scraping cyprinid Capoeta in Iran, applying the species- delimiting approaches Biology, Lund University, Lund, Sweden. Email: [email protected] General Mixed Yule- Coalescent (GMYC) and Poisson Tree Process (PTP) as well as haplotype network analyses. Using the BEAST program, we also examined temporal divergence patterns of Capoeta. The monophyly of the genus and the existence of three previously described main clades (Mesopotamian, Anatolian- Iranian, and Aralo- Caspian) were confirmed. However, the phylogeny proposed novel taxonomic findings within Capoeta. Results of GMYC, bPTP, and phylogenetic analyses were similar and suggested that species diversity in Iran is currently underestimated. At least four can- didate species, Capoeta sp4, Capoeta sp5, Capoeta sp6, and Capoeta sp7, are awaiting description. Capoeta capoeta comprises a species complex with distinct genetic line- ages. The divergence times of the three main Capoeta clades are estimated to have occurred around 15.6–12.4 Mya, consistent with a Mio- Pleistocene origin of the di- versity of Capoeta in Iran. The changes in Caspian Sea levels associated with climate fluctuations and geomorphological events such as the uplift of the Zagros and Alborz Mountains may account for the complex speciation patterns in Capoeta in Iran.

In Croatian watercourses, three members of the genus Barbus are found, B. balcanicus, B. barbus and B. plebejus, each occupying a specific ecological niche. This study examined cytochrome b (cyt b), a common genetic marker used to describe the structure and origin of fish populations to perform a phylogenetic reconstruction of the Danube barbel. Two methods of phylogenetic inference were used: maximum parsimony (MP) and maximum likelihood (ML), which yielded well supported trees of similar topology. The Median joining network (MJ) was generated and corroborated to show the divergence of three lineages of Barbus balcanicus on the Balkan Peninsula: Croatian, Serbian and Macedonian lineages that separated at the beginning of the Pleistocene.

  • Descripción De Nuevas Especies Animales De La Península Ibérica E Islas Baleares (1978-1994): Tendencias Taxonómicas Y Listado Sistemático
    Graellsia, 53: 111-175 (1997) DESCRIPCIÓN DE NUEVAS ESPECIES ANIMALES DE LA PENÍNSULA IBÉRICA E ISLAS BALEARES (1978-1994): TENDENCIAS TAXONÓMICAS Y LISTADO SISTEMÁTICO M. Esteban (*) y B. Sanchiz (*) RESUMEN Durante el periodo 1978-1994 se han descrito cerca de 2.000 especies animales nue- vas para la ciencia en territorio ibérico-balear. Se presenta como apéndice un listado completo de las especies (1978-1993), ordenadas taxonómicamente, así como de sus referencias bibliográficas. Como tendencias generales en este proceso de inventario de la biodiversidad se aprecia un incremento moderado y sostenido en el número de taxones descritos, junto a una cada vez mayor contribución de los autores españoles. Es cada vez mayor el número de especies publicadas en revistas que aparecen en el Science Citation Index, así como el uso del idioma inglés. La mayoría de los phyla, clases u órdenes mues- tran gran variación en la cantidad de especies descritas cada año, dado el pequeño núme- ro absoluto de publicaciones. Los insectos son claramente el colectivo más estudiado, pero se aprecia una disminución en su importancia relativa, asociada al incremento de estudios en grupos poco conocidos como los nematodos. Palabras clave: Biodiversidad; Taxonomía; Península Ibérica; España; Portugal; Baleares. ABSTRACT Description of new animal species from the Iberian Peninsula and Balearic Islands (1978-1994): Taxonomic trends and systematic list During the period 1978-1994 about 2.000 new animal species have been described in the Iberian Peninsula and the Balearic Islands. A complete list of these new species for 1978-1993, taxonomically arranged, and their bibliographic references is given in an appendix.
