Data from: Widespread hybridization and bidirectional introgression in sympatric species of coral reef fish

Hugo B. Harrison, Michael L. Berumen, Pablo Saenz-Agudelo, Eva Salas, David H. Williamson & Geoffrey P. Jones
Coral reefs are highly diverse ecosystems, where numerous closely related species often coexist. How new species arise and are maintained in these high geneflow environments have been long-standing conundrums. Hybridization and patterns of introgression between sympatric species provide a unique insight into the mechanisms of speciation and the maintenance of species boundaries. In this study, we investigate the extent of hybridization between two closely related species of coral reef fish: the common coral trout (Plectropomus...

Data from: Using a butterflyfish genome as a general tool for RAD-Seq studies in specialized reef fish

Joseph D. DiBattista, Pablo Saenz-Agudelo, Marek J. Piatek, Xin Wang, Manuel Aranda & Michael L. Berumen
Data from a large-scale restriction site associated DNA (RAD-Seq) study of nine butterflyfish species in the Red Sea and Arabian Sea provided a means to test the utility of a recently published draft genome (Chaetodon austriacus) and assess apparent bias in this method of isolating nuclear loci. We here processed double-digest restriction-site (ddRAD) associated DNA sequencing data to identify single nucleotide polymorphism (SNP) markers and their associated function with and without our reference genome to...

Data from: ClonEstiMate, a Bayesian method for quantifying rates of clonality of populations genotyped at two-time steps

Ronan Becheler, Jean-Pierre Masson, Sophie Arnaud-Haond, Fabien Halkett, Stéphanie Mariette, Marie-Laure Guillemin, Myriam Valero, Christophe Destombe & Solenn Stoeckel
Partial clonality is commonly used in Eukaryotes and has large consequences for their evolution and ecology. Assessing accurately the relative importance of clonal versus sexual reproduction matters for studying and managing such species. Here, we proposed a Bayesian approach, ClonEstiMate, to infer rates of clonality c from populations sampled twice over a short time interval, ideally one generation time. The method relies on the likelihood of the transitions between genotype frequencies of ancestral and descendent...

Data from: Phylogenomic analysis of the Chilean clade of Liolaemus lizards (Squamata: Liolaemidae) based on sequence capture data

Alejandra Panzera, Adam D. Leaché, Guillermo D'Elía & Pedro F. Victoriano
The genus Liolaemus is one of the most ecologically diverse and species-rich genera of lizards worldwide. It currently includes more than 250 recognized species, which have been subject to many ecological and evolutionary studies. Nevertheless, Liolaemus lizards have a complex taxonomic history, mainly due to the incongruence between morphological and genetic data, incomplete taxon sampling, incomplete lineage sorting and hybridization. In addition, as many species have restricted and remote distributions, this has hampered their examination...

Data from: The phenotypic correlates and quantitative genetics of masculinization in the rodent, Octodon degus

Derek A. Roff, Matthew E. Wolak, Loreto A. Correa & Mauricio Soto-Gamboa
In some mammals female characteristics have been shown to depend in part on the intrauterine position during development of female fetuses relative to male fetuses. Females developing in close proximity to males show behavioural, physiological and life history characteristics that are masculinized. With the exception of one inconclusive study, nothing is known of the genetic basis of this phenomenon. In this paper we reported an analysis of the quantitative genetic basis of masculinization, as indicated...

Data from: A genetic signature of the evolution of loss of flight in the Galapagos cormorant

Alejandro Burga, Wang Weiguang, Eyal Ben-David, Paul C. Wolf, Andrew M. Ramey, Claudio Verdugo, Karen Lyons, Patricia G. Parker & Leonid Kruglyak
We have a limited understanding of the genetic and molecular basis of evolutionary changes in the size and proportion of limbs. We studied wing and pectoral skeleton reduction leading to flightlessness in the Galapagos cormorant (Phalacrocorax harrisi). We sequenced and de novo assembled the genomes of four cormorant species and applied a predictive and comparative genomics approach to find candidate variants that may have contributed to the evolution of flightlessness. These analyses and cross-species experiments...

Data from: Hybridization between two cryptic filamentous brown seaweeds along the shore: analysing pre- and post-zygotic barriers in populations of individuals with varying ploidy levels

Alejandro E. Montecinos, Marie L. Guillemin, Lucia Couceiro, Akira F. Peters, Solenn Stoeckel, Myriam Valero & Marie-Laure Guillemin
We aimed to study the importance of hybridization between two cryptic species of the genus Ectocarpus, a group of filamentous algae with haploid-diploid life cycles that include the principal genetic model organism for the brown algae. In haploid-diploid species, the genetic structure of the two phases of the life cycle can be analysed separately in natural populations. Such life cycles provide a unique opportunity to estimate the frequency of hybrid genotypes in diploid sporophytes and...

Data from: Aerobic power and flight capacity in birds: a phylogenetic test of the heart-size hypothesis

Roberto F. Nespolo, Cesar González-Lagos, Jaiber J. Solano-Iguaran, Magnus Elfwing, Alvaro Garitano-Zavala, Santiago Mañosa, Juan Carlos Alonso & Jordi Altamiras
Flight capacity is one of the most important innovations in animal evolution; it only evolved in insects, birds, mammals and the extinct pterodactyls. Given that powered flight represents a demanding aerobic activity, an efficient cardiovascular system is essential for the continuous delivery of oxygen to the pectoral muscles during flight. It is well known that the limiting step in the circulation is stroke volume (the volume of blood pumped from the ventricle to the body...

Data from: Genomic patterns of diversity and divergence of two introduced salmonid species in Patagonia, South America

Shawn R. Narum, Pablo Gallardo, Cristian Correa, Amanda Matala, Daniel Hasselman, Ben J.G. Sutherland, Louis Bernatchez & Ben J. G. Sutherland
Invasive species have become widespread in aquatic environments throughout the world, yet there are few studies that have examined genomic variation of multiple introduced species in newly colonized environments. In this study, we contrast genomic variation in two salmonid species (anadromous Chinook Salmon, Oncorhynchus tshawytscha, 11,579 SNPs and resident Brook Charr Salvelinus fontinalis, 13,522 SNPs) with differing invasion success after introduction to new environments in South America relative to populations from their native range in...

Data from: Conformational dynamics in TRPV1 channels reported by an encoded coumarin amino acid

Ximena Steinberg, Marina A. Kasimova, Deny Cabezas-Bratesco, Jason D. Galpin, Ernesto Ladron-De-Guevara, Federica Villa, Vincenzo Carnevale, Leon Islas, Christopher A. Ahern & Sebastian E Brauchi
TRPV1 channels support the detection of noxious and nociceptive input. Currently available functional and structural data suggest that TRPV1 channels have two gates within their permeation pathway: one formed by a ′bundle-crossing′ at the intracellular entrance and a second constriction at the selectivity filter. To describe conformational changes associated with channel gating, the fluorescent non-canonical amino acid coumarin-tyrosine was genetically encoded at Y671, a residue proximal to the selectivity filter. Total internal reflection fluorescence microscopy...

Data from: High temporal variability in the occurrence of consumer–resource interactions in ecological networks

Daniela N. Lopez, Patricio A. Camus, Nelson Valdivia & Sergio A. Estay
Ecological networks have been used to represent interactions between species as fixed linkages despite that populations naturally oscillate over time and space. As such, the influence of the persistence of linkages between species in communities has been overlooked. Unfortunately, empirical analysis of the temporal variation of trophic networks is constrained by the lack of data with high spatial, temporal and taxonomic resolution. Here, we evaluate the spatiotemporal variability of multiple consumer-resource interactions to quantify the...

Data from: Kelp and dolphin gulls cause perineal wounds in South American fur seal pups (Arctocephalus australis) at Guafo Island, Chilean Patagonia

Mauricio Seguel, Francisco Muñoz, Felipe Montalva, Diego Perez-Venegas, Héctor Paves & Nicole Gottdenker
During five reproductive seasons, we documented the presence, extent and origin of perineal wounds in South American fur seal pups (Arctocephalus australis) on Guafo Island, Northern Chilean Patagonia. The seasonal prevalence of perineal wounds ranged from 5 to 9%, and new cases were more common at the end of the breeding season (February), when pups were on average two months old and were actively expelling hookworms (Uncinaria sp). Histologically, wounds corresponded to marked ulcerative lymphoplasmacytic...
