  • Analysis of the Diet Between an Invasive and Native Fishes in the Peruvian Amazon. Anthony Mazeroll [email protected] Introduct
    Analysis of the diet between an invasive and native fishes in the Peruvian Amazon. Anthony Mazeroll [email protected] Introduction Non-native species are the second greatest threat to global species biodiversity after land development (Vitousek, D'Antonio, Loope, Rejmanek, & Westbrooks, 1997). Due to the magnitude of this threat, it is vital that the impacts of exotic species are understood. Fish biodiversity is especially threatened by the ecological changes caused by non-native species (Gozlan, Britton, Cowx, & Copp, 2010). Having higher species diversity allows more ecological processes to take place, protecting the resources of that system, and making it more resilient to change (Folke, 2006). Adding outside inputs, such as additional non-native species, into an ecosystem can have beneficial or compromising effects depending on the amount and type. Invasive species have been shown to reduce native species richness and diversity of native organisms. Some have argued that the transportation of species from one ecosystem to another is actually beneficial for diversity, and non-native species are not really an environmental “problem”. Introductions of non-native species increase diversity at a local level because in the short term there will be a lag time where both non-native and natives can coexist (Lodge, Stein, Brown, Covich, Bronmark, Garvey and Klosiewski, 1998). Species entering a new ecosystem have to pass through a gauntlet of barriers before they can become established. The usual progression of invasion is: transportation to the new ecosystem, initial establishment, spread to a larger region, and then naturalization into the new community (Marchetti, Light, Moyle, and Viers, 2004).

  • Highlights Contrasting Karyotype Evolution Among Congeneric Species
    de Oliveira et al. Molecular Cytogenetics (2015) 8:56 DOI 10.1186/s13039-015-0161-4 RESEARCH Open Access Comparative cytogenetics in the genus Hoplias (Characiformes, Erythrinidae) highlights contrasting karyotype evolution among congeneric species Ezequiel Aguiar de Oliveira1,2, Luiz Antônio Carlos Bertollo1, Cassia Fernanda Yano1, Thomas Liehr3 and Marcelo de Bello Cioffi1* Abstract Background: The Erythrinidae fish family contains three genera, Hoplias, Erythrinus and Hoplerythrinus widely distributed in Neotropical region. Remarkably, species from this family are characterized by an extensive karyotype diversity, with 2n ranging from 39 to 54 chromosomes and the occurrence of single and/or multiple sex chromosome systems in some species. However, inside the Hoplias genus, while H. malabaricus was subject of many studies, the cytogenetics of other congeneric species remains poorly explored. In this study, we have investigated chromosomal characteristics of four Hoplias species, namely H. lacerdae, H. brasiliensis, H. intermedius and H. aimara. We used conventional staining techniques (C-banding, Ag-impregnation and CMA3 -fluorescence) as well as fluorescence in situ hybridization (FISH) with minor and major rDNA and microsatellite DNAs as probes in order to analyze the karyotype evolution within the genus. Results: All species showed invariably 2n = 50 chromosomes and practically identical karyotypes dominated only by meta- and submetacentric chromosomes, the absence of heteromorphic sex chromosomes, similar pattern of C-positive heterochromatin blocks and homologous Ag-NOR-bearing pairs. The cytogenetic mapping of five repetitive DNA sequences revealed some particular interspecific differences between them. However, the examined chromosomal characteristics indicate that their speciation was not associated with major changes in their karyotypes.

  • Chromosomes As Tools for Discovering Biodiversity – the Case of Erythrinidae Fish Family
    8 Chromosomes as Tools for Discovering Biodiversity – The Case of Erythrinidae Fish Family Marcelo de Bello Cioffi1, Wagner Franco Molina2, Roberto Ferreira Artoni3 and Luiz Antonio Carlos Bertollo1 1Universidade Federal de São Carlos 2Universidade Federal do Rio Grande do Norte 3Universidade Estadual de Ponta Grossa Brazil 1. Introduction Biodiversity or biological diversity is the diversity of life, extant or extinct. All of the biodiversity found on Earth today consists of many millions of distinct biological species and is the product of more than 4 billion years of evolution. Although the origin of life has not been correctly determined by science, some evidence suggests that life may already have been well-established only a few hundred million years after the formation of the Earth. Estimates of the number of extant global macroscopic species vary from 2 million to 100 million, with a best estimate of approximately 13–14 million, and the vast majority is represented by insects. However, biodiversity is not evenly distributed; rather, it varies greatly across the globe as well as within regions. A “biodiversity hotspot” can be defined as a region with a high level of endemic species, and while they can be found all over the world, the majority of them are forest areas, and most are located in the tropics (Myers, 1988). In fact, it is not a coincidence that the world’s biodiversity hotspots are also the centers of evolutionary change for numerous species. Evolution produces biodiversity, and in turn, a more diverse biological environment creates more selective pressures, which drive evolution. The biodiversity of a specific region is often measured by determining the number of species found there.

  • Fishes from the Upper Yuruá River, Amazon Basin, Peru
    Check List 5(3): 673–691, 2009. ISSN: 1809-127X LISTS OF SPECIES Fishes from the upper Yuruá river, Amazon basin, Peru Tiago P. Carvalho 1 S. June Tang 1 Julia I. Fredieu 1 Roberto Quispe 2 Isabel Corahua 2 Hernan Ortega 2 1 James S. Albert 1 University of Louisiana at Lafayette, Department of Biology. Lafayette, LA 70504, USA. E-mail: [email protected] 2 Museo de Historia Natural de la Universidad Nacional Mayor de San Marcos. Av. Arenales 1256, Lima 11, Peru. Abstract We report results of an ichthyological survey of the upper Rio Yuruá in southeastern Peru. Collections were made at low water (July-August, 2008) near the headwaters of the Brazilian Rio Juruá. This is the first of four expeditions to the Fitzcarrald Arch - an upland associated with the Miocene-Pliocene rise of the Peruvian Andes - with the goal of comparing the ichthyofauna across the headwaters of the largest tributary basins in the western Amazon (Ucayali, Juruá, Purús and Madeira). We recorded a total of 117 species in 28 families and 10 orders, with all species accompanied by tissue samples preserved in 100% ethanol for subsequent DNA analysis, and high-resolution digital images of voucher specimens with live color to facilitate accurate identification. From interviews with local fishers and comparisons with other ichthyological surveys of the region we estimate the actual diversity of fishes in the upper Juruá to exceed 200 species. Introduction The Yuruá river rises in the department of Ucayali The freshwater fish fauna of tropical South in Peru and runs into Brazilian territory, where it America is among the richest vertebrate faunas is known as Juruá river.
