Extra-pair paternity is a common reproductive strategy in many bird species. However, it remains unclear why extra-pair paternity occurs and why it varies among species and populations. Plovers (Charadrius spp.) exhibit considerable variation in reproductive behaviour and ecology, making them excellent models to investigate the evolution of social and genetic mating systems. We investigated inter- and intra-specific patterns of extra-pair parentage and evaluated three major hypotheses explaining extra-pair paternity using a comparative approach based on...
Data from: A new subfamily classification of the Leguminosae based on a taxonomically comprehensive phylogeny, Anne Bruneau, Nasim Azani, Marielle Babineau, Edeline Gagnon, Carole Sinou, Royce Steeves, Erin Zimmerman, C. Donovan Bailey, Lynsey Kovar, Madhugiri Nageswara-Rao, Hannah Banks, RuthP. Clark, Manuel De La Estrella, Peter Gasson, GeoffreyC. Kite, BenteB. Klitgaard, GwilymP. Lewis, Danilo Neves, Gerhard Prenner, María De Lourdes Rico-Arce, ArianeR. Barbosa, Maria Cristina López-Roberts, Luciano Paganucci De Queiroz, PétalaG. Ribeiro … & Tingshuang Yi
The classification of the legume family proposed here addresses the long-known non-monophyly of the traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supported monophyletic subfamilies. This new classification uses as its framework the most comprehensive phylogenetic analyses of legumes to date, based on plastid matK gene sequences, and including near-complete sampling of genera (698 of the currently recognised 765 genera) and ca. 20% (3696) of known species. The matK gene region has been the most...
Data from: Long-term in situ persistence of biodiversity in tropical sky-islands revealed by landscape genomicsAlicia Mastretta-Yanes, Alexander T. Xue, Alejandra Moreno-Letelier, Tove H. Jørgensen, Nadir Alvarez, Daniel Piñero, Brent C. Emerson & Tove H. Jorgensen
Tropical mountains are areas of high species richness and endemism. Two historical phenomena may have contributed to this: (1) fragmentation and isolation of habitats may have promoted the genetic differentiation of populations and increased the possibility of allopatric divergence and speciation, and; (2) the mountain areas may have allowed long-term population persistence during global climate fluctuations. These two phenomena have been studied using either species occurrence data or estimating species divergence times. However, only few...
Data from: Habitat fragmentation and the prevalence of parasites (Diptera, Streblidae) on three Phyllostomid bat speciesBeatriz Bolívar-Cimé, Alan Cuxim-Koyoc, Enrique Reyes-Novelo, Juan B. Morales-Malacara, Javier Laborde & Rafael Flores-Peredo
Ectoparasitism in bats seems to be influenced strongly by the type of roost preferred by the hosts, and group size; however, the effect of habitat loss and fragmentation on the prevalence of ectoparasites in bats has scarcely been studied. In northeastern Yucatan, Mexico, we estimated the prevalence of infestation by Streblidae flies in three phyllostomid bat species with different roost preferences (caves, trees, or both) in two types of landscape matrices (tropical semi-deciduous forest and...
Data from: Taxonomic and functional ant diversity along a secondary successional gradient in a tropical forestMaya Rocha-Ortega, Xavier Arnan, José Domingos Ribeiro-Neto, Inara R. Leal, Mario E. Favila & Miguel Martínez-Ramos
The taxonomic diversity (TD) of tropical flora and fauna tends to increase during secondary succession. This increase may be accompanied by changes in functional diversity (FD), although the relationship between TD and FD is not well understood. To explore this relationship, we examined the correlations between the TD and FD of ants and forest age in secondary forests at the α- and β-diversity levels using single- and multi-trait-based approaches. Our objectives were to understand ant...
The central-abundance hypothesis predicts that local adaptation is a function of the distance to the center of a species’ geographic range. To test this hypothesis, we gathered genomic diversity data from 49 populations, 646 individuals and 33,464 SNPs of two wild relatives of maize, the teosintes Zea mays ssp. parviglumis and Zea. mays. ssp. mexicana. We examined the association between the distance to their climatic and geographic centroids and the enrichment of SNPs bearing signals...
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: Sexual dimorphism and retinal mosaic diversification following the evolution of a violet receptor in butterfliesKyle J. McCulloch, Furong Yuan, Ying Zhen, Matthew L. Aardema, Gilbert Smith, Jorge Llorente-Bousquets, Peter Andolfatto & Adriana D. Briscoe
Numerous animal lineages have expanded and diversified the opsin-based photoreceptors in their eyes underlying color vision behavior. However, the selective pressures giving rise to new photoreceptors and their spectral tuning remain mostly obscure. Previously, we identified a violet receptor (UV2) that is the result of a UV opsin gene duplication specific to Heliconius butterflies. At the same time the violet receptor evolved, Heliconius evolved UV-yellow coloration on their wings, due to the pigment 3-hydroxykynurenine (3-OHK)...
Data from: Experiencing El Niño conditions during early life reduces recruiting probabilities but not adult survivalSergio Ancona, J. Jaime Zúñiga-Vega, Cristina Rodríguez & Hugh Drummond
In wild long-lived animals, analysis of impacts of stressful natal conditions on adult performance has rarely embraced the entire age-span, and the possibility that costs are expressed late in life has seldom been examined. Using 26 years of data from 8,541 fledglings and 1,310 adults of the blue-footed booby (Sula nebouxii), a marine bird that can live up to 23 years, we tested whether experiencing the warm waters and food scarcity associated with El Niño...
Data from: Do male fish prefer them big and colourful? Non-random male courtship effort in a viviparous fish with negligible paternal investmentMarcela Méndez-Janovitz & Constantino Macías Garcia
In the majority of sexual species, there are asymmetries in reproductive effort, with males typically investing more in securing matings and females investing more in producing offspring. This causes males to mate less discriminately than females. Yet males may also become choosy if the following conditions are met: (a) that females vary in their reproductive value, (b) that males can perceive this variation, and (c) that mating with one female reduces the possibility of mating...
Data from: Epigenomic study identifies a novel mesenchyme homeobox2-GLI1 transcription axis involved in cancer drug resistance, overall survival and therapy prognosis in lung cancer patientsLeonel Armas-López, Patricia Piña-Sanchez, Oscar Arrieta, Enrique Guzman De Alba, Blanca Ortiz-Quintero, Patricio Santillán-Doherty, David C. Christiani, Joaquín Zúñiga & Federico Ávila-Moreno
Several homeobox-related gene (HOX) transcription factors such as mesenchyme HOX-2 (MEOX2) have previously been associated with cancer drug resistance, malignant progression and/or clinical prognostic responses in lung cancer patients; however, the mechanisms involved in these responses have yet to be elucidated. Here, an epigenomic strategy was implemented to identify novel MEOX2 gene promoter transcription targets and propose a new molecular mechanism underlying lung cancer drug resistance and poor clinical prognosis. Chromatin immunoprecipitation (ChIP) assays derived...
We present a statistical analysis of music scores from different composers using detrended fluctuation analysis. We find different fluctuation profiles that correspond to distinct auto-correlation structures of the musical pieces. Further, we reveal evidence for the presence of nonlinear auto-correlations by estimating the detrended fluctuation analysis of the magnitude series, a result validated by a corresponding study of appropriate surrogate data. The amount and the character of nonlinear correlations vary from one composer to another....
Data from: A phylogenetic, biogeographic, and taxonomic study of all extant species of Anolis (Squamata; Iguanidae)Steven Poe, Adrian Nieto-Montes De Oca, Omar Torres-Carvajal, Kevin De Queiroz, Julian A. Velasco, Brad Truett, Levi N. Gray, Mason J. Ryan, Gunther Kohler, Fernando Ayala-Varela & Ian Latella
Anolis lizards (anoles) are textbook study organisms in evolution and ecology. Although several topics in evolutionary biology have been elucidated by the study of anoles, progress in some areas has been hampered by limited phylogenetic information on this group. Here we present a phylogenetic analysis of all 379 extant species of Anolis, with new phylogenetic data for 139 species including new DNA data for 101 species. We use the resulting estimates as a basis for...
