Data from: Transgenerational effects of sexual interactions and sexual conflict: non-sires boost the fecundity of females in the following generation

Francisco Garcia-Gonzalez & Damian K. Dowling
The consequences of sexual interactions extend beyond the simple production of offspring. These interactions typically entail direct effects on female fitness, but may also impact the life histories of later generations. Evaluating the cross-generational effects of sexual interactions provides insights into the dynamics of sexual selection and conflict. Such studies can elucidate whether offspring fitness optima diverge across sexes upon heightened levels of sexual interaction among parents. Here, we found that, in Drosophila melanogaster, components...

Data from: DNA barcoding and minibarcoding as a powerful tool for feather mite studies

Jorge Doña, Javier Diaz-Real, Sergey Mironov, Pilar Bazaga, David Serrano & Roger Jovani
Feather mites (Astigmata: Analgoidea and Pterolichoidea) are among the most abundant and commonly occurring bird ectosymbionts. Basic questions on the ecology and evolution of feather mites remain unanswered because feather mite species identification is often only possible for adult males, and it is laborious even for specialized taxonomists, thus precluding large-scale identifications. Here, we tested DNA barcoding as a useful molecular tool to identify feather mites from passerine birds. Three hundred and sixty-one specimens of...

Data from: Test of biotic and abiotic correlates of latitudinal variation in defences in the perennial herb Ruellia nudiflora

Luis Abdala-Roberts, Xoaquín Moreira, Sergio Rasmann, Victor Parra-Tabla & Kailen A. Mooney
1. Geographic variation in abiotic factors and species interactions is widespread and is hypothesized to generate concomitant patterns of species trait variation. For example, higher rates of herbivory at lower latitudes are thought to select for increased plant defences, although latitudinal variation in defences may also be influenced directly by abiotic factors and indirectly by predators and parasitoids reducing herbivore pressure. 2. We measured defences of the herb Ruellia nudiflora among 30 populations spanning a...

Data from: Field heritability of a plant adaptation to fire in heterogeneous landscapes

Maria Clara Castellanos, Santiago C. González-Martínez & Juli G. Pausas
The strong association observed between fire regimes and variation in plant adaptations to fire suggests a rapid response to fire as an agent of selection. It also suggests that fire-related traits are heritable, a precondition for evolutionary change. One example is serotiny, the accumulation of seeds in unopened fruits or cones until the next fire, an important strategy for plant population persistence in fire-prone ecosystems. Here, we evaluate the potential of this trait to respond...

Data from: Detection of tephra layers in Antarctic sediment cores with hyperspectral imaging

Ismael F. Aymerich, Marc Oliva, Santiago Giralt & Julio Martín-Herrero
Tephrochronology uses recognizable volcanic ash layers (from airborne pyroclastic deposits, or tephras) in geological strata to set unique time references for paleoenvironmental events across wide geographic areas. This involves the detection of tephra layers which sometimes are not evident to the naked eye, including the so-called cryptotephras. Tests that are expensive, time-consuming, and/or destructive are often required. Destructive testing for tephra layers of cores from difficult regions, such as Antarctica, which are useful sources of...

Data from: Systems biology of tissue-specific response to Anaplasma phagocytophilum reveals differentiated apoptosis in the tick vector Ixodes scapularis

Nieves Ayllón, Margarita Villar, Ruth C. Galindo, Katherine M. Kocan, Radek Sima, Juan A. López, Jesús Vázquez, Pilar Alberdi, Alejandro Cabezas-Cruz, Petr Kopáček & José De La Fuente
Anaplasma phagocytophilum is an emerging pathogen that causes human granulocytic anaplasmosis. Infection with this zoonotic pathogen affects cell function in both vertebrate host and the tick vector, Ixodes scapularis. Global tissue-specific response and apoptosis signaling pathways were characterized in I. scapularis nymphs and adult female midguts and salivary glands infected with A. phagocytophilum using a systems biology approach combining transcriptomics and proteomics. Apoptosis was selected for pathway-focused analysis due to its role in bacterial infection...

Data from: Bypass of genetic constraints during mutator evolution to antibiotic resistance

Alejandro Couce, Alexandro Rodríguez-Rojas, Jesús Blázquez, A. Rodriguez-Rojas & J. Blazquez
Genetic constraints can block many mutational pathways to optimal genotypes in real fitness landscapes, yet the extent to which this can limit evolution remains to be determined. Interestingly, mutator bacteria elevate only specific types of mutations, and therefore could be very sensitive to genetic constraints. Testing this possibility is not only clinically relevant, but can also inform about the general impact of genetic constraints in adaptation. Here, we evolved 576 populations of two mutator and...

Data from: Bees explain floral variation in a recent radiation of Linaria

José Luis Blanco-Pastor, Concepción Ornosa, Daniel Romero, Isabel Liberal, José M. Gómez & Pablo Vargas
The role of pollinators in floral divergence has long attracted the attention of evolutionary biologists. Although abundant studies have reported the effect of pollinators on flower shape variation and plant speciation, the influence of pollinators on plant species differentiation during rapid radiations and the specific consequences of shifts among similar pollinators are not well understood. Here, we evaluate the association between pollinators and floral morphology in a closely related and recently diversifying clade of Linaria...

Data from: Light accelerates plant responses to warming

Pieter De Frenne, Francisco Rodríguez-Sánchez, An De Schrijver, David A. Coomes, Martin Hermy, Pieter Vangansbeke & Kris Verheyen
Competition for light has profound effects on plant performance in virtually all terrestrial ecosystems. Nowhere is this more evident than in forests, where trees create environmental heterogeneity that shapes the dynamics of forest-floor communities1,​2,​3. Observational evidence suggests that biotic responses to both anthropogenic global warming and nitrogen pollution may be attenuated by the shading effects of trees and shrubs4,​5,​6,​7,​8,​9. Here we show experimentally that tree shade is slowing down changes in below-canopy communities due to...

Data from: MSAP markers and global cytosine methylation in plants: a literature survey and comparative analysis for a wild growing species

Conchita Alonso, Ricardo Pérez, Pilar Bazaga, Mónica Medrano & Carlos M. Herrera
Methylation of DNA cytosines affects whether transposons are silenced and genes are expressed, and is a major epigenetic mechanism whereby plants respond to environmental change. Analyses of methylation-sensitive amplification polymorphism (MS-AFLP or MSAP) have been often used to assess methyl-cytosine changes in response to stress treatments and, more recently, in ecological studies of wild plant populations. MSAP technique does not require a sequenced reference genome and provides many anonymous loci randomly distributed over the genome...

Data from: Long telomeres are associated with clonality in wild populations of the fissiparous starfish Coscinasterias tenuispina

Alex Garcia-Cisneros, Rocío Pérez-Portela, Bethanie C. Almroth, Sofie Degerman, Creu Palacín & Helen Nilsson Sköld
TelTelomeres usually shorten during an organism’s lifespan and have thus been used as an aging and health marker. When telomeres become sufficiently short, senescence is induced. The most common method of restoring telomere length is via telomerase reverse transcriptase activity, highly expressed during embryogenesis. However, although asexual reproduction from adult tissues has an important role in the life cycles of certain species, its effect on the aging and fitness of wild populations, as well as...

Data from: Paleo-islands as refugia and sources of genetic diversity within volcanic archipelagos: The case of the widespread endemic Canarina canariensis (Campanulaceae)

Mario Mairal, Isabel Sanmartín, Juan José Aldasoro, Victoria Culshaw, Ioanna Manolopoulou & Marisa Alarcón
Geographical isolation by oceanic barriers and climatic stability has been postulated as some of the main factors driving diversification within volcanic archipelagos. However, few studies have focused on the effect that catastrophic volcanic events have had on patterns of within-island differentiation in geological time. This study employed data from the chloroplast (cpDNA haplotypes) and the nuclear (AFLPs) genomes to examine the patterns of genetic variation in Canarina canariensis, an iconic plant species associated with the...

Data from: Persistent natural acidification drives major distribution shifts in marine benthic ecosystems

Cristina Linares, Montserrat Vidal, Miquel Canals, Diego Kersting, David Amblas, Eneko Aspillaga, Emma Cebrian, Antonio Delgado-Huertas, David Diaz, Joaquim Garrabou, Bernat Hereu, Laura Navarro, Nuria Teixido & Enric Ballesteros
Ocean acidification is one of the main stressors affecting marine ecosystems. Rare CO2 vents offer a unique opportunity to investigate the response of benthic ecosystems to acidification. However, the benthic habitats that have been investigated so far are mainly very shallow water (≤5 m depth) and, therefore, to habitats that are poorly representative of the broad range of habitats that occur on the continental shelf. Here, we show that a decrease from pH 8.1 to...

Data from: Telomere dynamics in parasitic great spotted cuckoos and their magpie hosts

Juan J. Soler, Cristina Ruiz Castellano, Josué Martínez De La Puente, Gustavo Tomás, Magdalena Ruiz-Rodríguez & Jordi Figuerola
Although little is known on the impact of environment on telomere length dynamics, it has been suggested to be affected by stress, lifestyle and/or life-history strategies of animals. We here compared telomere dynamics in erythrocytes of hatchlings and fledglings of the brood parasite great spotted cuckoos (Clamator glandarius) and of magpies (Pica pica), their main host in Europe. In magpie chicks, telomere length decreased from hatching to fledging while no significant change in telomere length...

Data from: Marine biodiversity in Juan Fernández and Desventuradas Islands, Chile: global endemism hotspots

Alan M. Friedlander, Enric Ballesteros, Jennifer E. Caselle, Carlos F. Gaymer, Alvaro T. Palma, Ignacio Petit, Eduardo Varas, Alex Muñoz Wilson & Enric Sala
The Juan Fernández and Desventuradas islands are among the few oceanic islands belonging to Chile. They possess a unique mix of tropical, subtropical, and temperate marine species, and although close to continental South America, elements of the biota have greater affinities with the central and south Pacific owing to the Humboldt Current, which creates a strong biogeographic barrier between these islands and the continent. The Juan Fernández Archipelago has ~ 700 people, with the major...

Data from: Ancient vicariance and climate-driven extinction explain continental-wide disjunctions in Africa: the case of the Rand Flora genus Canarina (Campanulaceae)

Mario Mairal, Lisa Pokorny, Marisa Alarcón, Juan J. Aldasoro & Isabel Sanmartín
Transoceanic distributions have attracted the interest of scientists for centuries. Less attention has been paid to the evolutionary origins of ‘continent-wide’ disjunctions, in which related taxa are distributed across isolated regions within the same continent. A prime example is the ‘Rand Flora’ pattern, which shows sister taxa disjunctly distributed in the continental margins of Africa. Here, we explore the evolutionary origins of this pattern using the genus Canarina, with three species: C. canariensis, associated with...

Data from: Range-wide population genetics and variation in morph ratio in style-dimorphic Narcissus papyraceus (Amaryllidaceae)

Violeta I. Simón-Porcar, F. Xavier Picó & Juan Arroyo
Premise of the study: Theoretical models state that natural selection and mating patterns account for floral morph ratio in style- polymorphic plants. However, the demographic history of populations can also influence variation in morph ratios. If so, we hypothesize an association between the morph ratios and the genetic structure across populations. Methods: We used nuclear microsatellites to assess genetic variation and structure in populations of Narcissus papyraceus, a style-dimorphic plant whose floral morph ratios (L-morph...

Data from: Deep-sea, deep-sequencing: metabarcoding extracellular DNA from sediments of marine canyons

Magdalena Guardiola, María Jesús Uriz, Pierre Taberlet, Eric Coissac, Owen Simon Wangensteen & Xavier Turon
Marine sediments are home to one of the richest species pools on Earth, but logistics and a dearth of taxonomic work-force hinders the knowledge of their biodiversity. We characterized α- and β-diversity of deep-sea assemblages from submarine canyons in the western Mediterranean using an environmental DNA metabarcoding. We used a new primer set targeting a short eukaryotic 18S sequence (ca. 110 bp). We applied a protocol designed to obtain extractions enriched in extracellular DNA from...

Data from: Sexual selection protects against extinction

Alyson J. Lumley, Łukasz Michalczyk, James J. N. Kitson, Lewis G. Spurgin, Catriona A. Morrison, Joanne L. Godwin, Matthew E. Dickenson, Oliver Y. Martin, Brent C. Emerson, Tracey Chapman & Mattew J. G. Gage
Reproduction through sex carries substantial costs, mainly because only half of sexual adults produce offspring. It has been theorized that these costs could be countered if sex allows sexual selection to clear the universal fitness constraint of mutation load. Under sexual selection, competition between (usually) males and mate choice by (usually) females create important intraspecific filters for reproductive success, so that only a subset of males gains paternity. If reproductive success under sexual selection is...
