Abstract Stable isotope analysis provides a powerful tool to identify the energy sources which fuel consumers, understand trophic interactions and infer consumer position (TP), an important concept that describes ecological role of consumers in food webs. However, current methods for estimating TP using stable isotopes are limited do not fulfil complete potential isotopic approach. For instance, researchers typically use point estimates key parameters including discrimination factors...
Pollution and its effects have been of major concern in recent decades. Many strategies markers developed to assess their on biota. Cytochrome P450 (CYP) genes received significant attention this context because relationship with detoxification activation exogenous compounds. While expression has identified as a pollution exposure biomarker, most cases, it tested only after acute exposures for CYP associated To elucidate gene patterns under chronic exposure, we used the silverside...
The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for fishes. Our NEOTROPICAL FRESHWATER FISHES data set is to produce a large-scale inventory, covering entire from Mexico and Caribbean in north southern limits Argentina, Paraguay, Chile, Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, represented by occurrence abundance data. number of species numerous orders are as follows: Characiformes...
Following study of the external morphology and its unmatched variability throughout ontogeny a re-examination selected morphological characters based on many specimens diplomystids from Central South Chile, we revised emended previous specific diagnoses consider Diplomystes chilensis , D. nahuelbutaensis camposensis Olivaichthys viedmensis (Baker River) to be valid species. Another group, previously identified as sp., D . spec., aff. cf. inhabiting rivers between Rapel Itata Basins is given...
Quantifying the tropic position (TP) of an animal species is key to understanding its ecosystem function. While both bulk and compound-specific analyses stable isotopes are widely used for this purpose, few studies have assessed consistency between within such approaches. Champsocephalus gunnari a specialist teleost that predates almost exclusively on Antarctic krill Euphausia superba . This well-known nearly constant trophic relationship makes C. particularly suitable assessing TP methods...
A new genus and species, Pseudorestias lirimensis, is described from the southern part of Chilean Altiplano. While sharing several characters that clearly align species with Orestias, this fish characterized by numerous autapomorphies: Meckel cartilage a continuous broadly expands posteriorly (in large specimens, it keeps its anterior resorbed posteriorly), basibranchials are fused into one long element, second pharyngobranchial not displaced dorsally over tooth plate 3+4, but they aligned,...
ABSTRACT A study including morphological characters and mitogenomics of South American Australian fishes previously assigned to Percichthyidae was conducted. Results generated from these different data sets reveal major disagreements concerning the content interpretation so-called percichthyids. phylogenetic analysis based on 54 suggests existence two clades: (1) Percichthyidae, Percichthys taxa Macquaria australasica, (= Plectroplites), Maccullochella; (2) Perciliidae with genus Percilia at...
AbstractThe killifish Orestias ascotanensis is endemic to the small isolated springs of Ascotán salt pan in Central High Andes, Chile. Due populations, mining activity, and increasing aridity, this species catalogued danger extinction. The complete mitochondrial genome O. ascotanesis was assembled with an Ion Torrent sequencer (chip 318) that produced 2.61 million reads. 16 617 bp entire consisted 22 transfer RNAs, 2 ribosomal 13 protein-coding genes, a control region, showing gene...

Species diagnosis is essential to assess the level of mislabeling or misnamed seafood products such as sushi. In Chile, sushi typically includes salmon main ingredient, but species used are rarely declared on menu. order identify which included in Chilean market, we analyzed 84 individual rolls sold "salmon" from outlets ten cities across Chile. Using a polymerase chain reaction-restriction fragment length polymorphism protocol (PCR-RFLP), identified mislabeled and products. Atlantic was...
The killifish genus Orestias is endemic to freshwater ecosystems in the High Andes of Peru, Bolivia and Chile. Phylogenetic phylogeographic studies with partial mitochondrial genes have failed resolve relationship among species, needing more comprehensive approaches. In this study, we described complete genome sp. from Lirima, northern Chile, aim provide useful data for phylogenetic purposes species delimitation. was assembled 2.6 million reads obtained through an Ion Torrent (chip 318)...

ABSTRACT On the flanks of > 6000 m Andean volcanoes that tower over Atacama Desert, leaf‐eared mice ( Phyllotis vaccarum ) live at extreme elevations surpass known vegetation limits. The diet these in barren, hyperarid environments has been subject much speculation. According to arthropod fallout hypothesis, sustenance is provided by windblown insects accumulate snowdrifts (“aolian deposits”). Mice may also feed on saxicolous lichen or forms cryptic have yet be discovered such high...
Cheilodactylus variegatus is a common benthivorous marine fish inhabiting in rocky subtidal habitats the eastern south Pacific coast of Chile and Peru. However, its biology ecology are relatively understudied taxonomic assignment has been debated recently. The complete mitochondrial genome was assembled de novo mapped to reference using 5.97 million reads obtained through Ion Torrent next generation sequencing, resulting circular sequence 16,652 bp length. Gene composition arrangement...
The complete sequence of the mitochondrial genome for Chilean silverside Basilichthys microlepidotus is reported first time. entire was 16,544 bp in length (GenBank accession no. KM245937); gene composition and arrangement conformed to that most fishes contained typical structure 2 rRNAs, 13 protein-coding genes, 22 tRNAs a non-coding region. assembled mitogenome validated against sequences COI Control Region previously sequenced our lab, functional genes from RNA-Seq data same species two...
The present study combined uniparental mtDNA and biparental SNPs to illuminate the invasion colonization pathways of rainbow trout, Oncorhynchus mykiss, one world's most widespread invasive fishes, that has been intensively propagated in Chile, South America. specific aims were (i) evaluate potential donor populations, which could be either from species' native range North America or introduced populations Europe, by comparing D-loop/control region haplotypes; (ii) assess factors have shaped...
