Data from: \"De novo assembled transcriptome of organs involved in reproduction in an endangered endemic Iberian cyprinid fish (Squalius pyrenaicus)\" in Genomic Resources Notes Accepted 1 June 2015 to 31 July 2015

Miguel P. Machado, Joana Pinho, Ana R. Grosso, Manfred Schartl, Maria M. Coelho, C. Vilas, Wolfgang Arthofer, Alexander Rief, Birgit C. Schlick-Steiner, Julia Seeber, Florian M. Steiner, D. Conklin, A. Estonba, J. Langa & I. Montes
Sex determination systems are diverse, especially among fish, and include genetic and/or environmental components. Unexpectedly for such a basic aspect of development, sex determination systems change rapidly during evolution and gonadal fate is not ultimate, being actively maintained lifelong. Here, sequences of expressed genes involved in maintenance of gonad identity and reproduction processes were obtained through transcriptome assembly of the brain-gonadal axis tissues of a freshwater fish inhabiting highly variable environments, the gonochoristic Iberian fish...

Data from: Non-trophic plant-animal interactions mediate positive density dependence among conspecific saplings

Magdalena Żywiec, Jose M. Fedriani, Przemysław Kurek & Jan Holeksa
Trophic plant-animal interactions (e.g. browsing by ungulates, insect attack) are an important and well-studied source of mortality in many tree populations. Non-trophic tree-animal interactions (e.g. deer antler rubbing) also frequently lead to tree death, and thus have significant effects on forest ecosystem functioning, but they are much less well studied than trophic interactions are. As deer populations have increased in recent decades in the Northern Hemisphere, their impact on tree populations via browsing and antler...

Data from: Deep mitochondrial introgression and hybridization among ecologically divergent vole species

Cristiane Bastos-Silveira, Sara M. Santos, Rita Monarca, Maria Da Luz Mathias & Gerald Heckel
The completion of speciation is typically difficult to ascertain in rapidly diverging taxa but the amount of hybridization and gene flow in sympatry or parapatry contains important information about the level of reproductive isolation achieved. Here we examined the progress in speciation between the Mediterranean (Microtus duodecimcostatus) and the Lusitanian pine vole (M. lusitanicus) which are part of the most rapid radiation of species known in mammals. These two Iberian pine voles are classified as...

Data from: From nature to the labratory: the impact of founder effects in adaptation

Josiane Santos, Marta Pascual, Pedro Simões, Inês Fragata, Margarida Lima, Bárbara Kellen, Marta Santos, Ana Marques, Michael R. Rose & Margarida Matos
Most founding events entail a reduction of population size, which in turn leads to genetic drift effects that can deplete alleles. Besides reducing neutral genetic variability, founder effects can in principle shift additive genetic variance for phenotypes that underlie fitness. This could then lead to different rates of adaptation among populations that have undergone a population size bottleneck as well as an environmental change, even when these populations have a common evolutionary history. Thus theory...

Data from: P53 gene discriminates two ecologically divergent sister species of pine voles

Ana S. Quina, Cristiane Bastos-Silveira, Marcos Miñarro, Jacint Ventura, Rafael Jiménez, Octávio S. Paulo & Maria L. Mathias
Genes with relevant roles in the differentiation of closely-related species are likely to have diverged simultaneously with the species and more accurately reproduce the species tree. The Lusitanian (Microtus lusitanicus) and Mediterranean (M. duodecimcostatus) pine voles are two recently separated sister species with fossorial lifestyles whose different ecological, physiological and morphological phenotypes reflect the better adaptation of M. duodecimcostatus to the underground habitat. Here we asked whether the differentiation of M. lusitanicus and M. duodecimcostatus...

Data from: Demographic history of a recent invasion of house mice on the isolated Island of Gough

Melissa M. Gray, Daniel Wegmann, Ryan J. Haasl, Michael A. White, Sofia I. Gabriel, Jeremy B. Searle, Richard J. Cuthbert, Peter G. Ryan & Bret A. Payseur
Island populations provide natural laboratories for studying key contributors to evolutionary change, including natural selection, population size, and the colonization of new environments. The demographic histories of island populations can be reconstructed from patterns of genetic diversity. House mice (Mus musculus) inhabit islands throughout the globe, making them an attractive system for studying island colonization from a genetic perspective. Gough Island, in the central South Atlantic Ocean, is one of the remotest islands in the...

Data from: How much can history constrain adaptive evolution? A real time evolutionary approach of inversion polymorphisms in Drosophila subobscura

Inês Fragata, Miguel Lopes-Cunha, Margarida Bárbaro, Bárbara Kellen, Margarida Lima, Marta A. Santos, Gonçalo S. Faria, Mauro Santos, Margarida Matos & Pedro Simões
Chromosomal inversions are present in a wide range of animals and plants, having an important role in adaptation and speciation. Although empirical evidence of their adaptive value is abundant, the role of different processes underlying evolution of chromosomal polymorphisms is not fully understood. History and selection are likely to shape inversion polymorphism variation to an extent yet largely unknown. Here, we perform a real-time evolution study addressing the role of historical constraints and selection in...

Preserving wintering frugivorous birds in agro‐ecosystems under land use change: Lessons from intensive and super-intensive olive orchards

Rui Morgado, Rui Pedroso, Miguel Porto, José Herrera, Francisco Rego, Francisco Moreira & Pedro Beja
Fleshy-fruit production is becoming more intensive worldwide, but how this affects frugivorous birds is poorly known. In the Mediterranean region, intensive and super-intensive olive orchards are fast expanding, potentially affecting millions of wintering songbirds. Here we test the idea that intensification may benefit frugivorous birds, at least locally, due to increased fruit availability, while negatively affecting the wider wintering bird community due to intensive management, structural simplification and landscape homogenisation. We estimated olive abundance and...

Following Darwin’s footsteps: Evaluating the impact of an activity designed for elementary school students to link historically important evolution key concepts on their understanding of natural selection

Xana Sá-Pinto, Alexandre Pinto, Joana Ribeiro, Inês Sarmento, Patrícia Pessoa, Leonor L. Rodrigues, Lucía Vázquez-Ben, Evangelia Mavrikaki & Joaquim Bernardino Lopes
While several researchers have suggested that evolution should be explored from the initial years of schooling, little information is available on effective resources to enhance elementary school students’ level of understanding of evolution by natural selection (LUENS). For the present study, we designed, implemented and evaluated an educational activity planned for fourth graders to explore concepts and conceptual fields that were historically important for the discovery of natural selection. Observation field notes and students’ productions...

Oliveira Santos, Caroline Rinaldi, Renato Rinaldi, Salvatore Siciliano, Vidal Martín, Manuel Carillo, Ana Carolina O. De Meirelles, Valentina Franco-Trecu, Nelson J. R. Fagundes, Ignacio Benites Moreno, L. Lacey Knowles & Ana Rita Amaral
The Atlantic spotted dolphin (Stenella frontalis) is endemic to tropical, subtropical, and warm temperate waters of the Atlantic Ocean. Throughout its distribution, both geographic distance and environmental variation may contribute to population structure of the species. In this study we follow a seascape genetics approach to investigate population differentiation of Atlantic spotted dolphins based on a large worldwide dataset and the relationship with marine environmental variables. The results revealed that the Atlantic spotted dolphin exhibits...

A Escola do Magistério Primário de Lisboa durante o estado novo: atores, currículo, pedagogia

Joaquim Pintassilgo
O presente texto propõe-se analisar o pensamento educativo de alguns dos principais professores de pedagogia e de didática da Escola do Magistério Primário de Lisboa durante o período do Estado Novo. Procuraremos, em particular, refletir sobre a forma como esses professores interpretaram a tradição da “escola ativa”, que procuram corporizar, conjugando-a com as ideias conservadoras e de inspiração católica que, na maior parte dos casos, guia o seu pensamento num contexto muito particular, o do...

Major inconsistencies of inferred population genetic structure estimated in a large set of domestic horse breeds using microsatellites

Stephan Funk, Jose Luis Vega-Pla, Cristina Luis, Gus Cothran & Rytis Juras
STRUCTURE remains the most applied tool aimed at recovering the true, but unknown, population structure from observed microsatellite data or other genetic markers. About 30% of STRUCTURE-based studies could not be reproduced (Gilbert et al., 2012). Here we use a large set of data from 2323 horses from 93 domestic breeds plus the Przewalski horse, typed at 15 microsatellite markers, to evaluate how program settings, in particular the so far insufficiently evaluated number of replicates,...

The genetic ancestry of American Creole cattle inferred from uniparental and autosomal genetic markers

Oscar Cortes Gardyn, Catarina Ginja, Luis Telo De Gama, Amparo Martínez, Inmaculada Martín Burriel & Juan Vicente Delgado
Cattle imported from the Iberian Peninsula spread throughout America in the early years of discovery and colonization to originate Creole breeds, which adapted to a wide diversity of environments and later received infuences from other origins, including zebu cattle in more recent years. We analyzed uniparental genetic markers and autosomal microsatellites in DNA samples from 114 cattle breeds distributed worldwide, including 40 Creole breeds representing the whole American continent, and samples from the Iberian Peninsula,...

Data from: Evolution of Drosophila resistance against different pathogens and infection routes entails no detectable maintenance costs

Vitor G. Faria, Nelson E. Martins, Tânia Paulo, Luís Teixeira, Élio Sucena & Sara Magalhães
Pathogens exert a strong selective pressure on hosts, entailing host adaptation to infection. This adaptation often affects negatively other fitness-related traits. Such trade-offs may underlie the maintenance of genetic diversity for pathogen resistance. Trade-offs can be tested with experimental evolution of host populations adapting to parasites, using two approaches: (1) measuring changes in immunocompetence in relaxed-selection lines and (2) comparing life-history traits of evolved and control lines in pathogen-free environments. Here, we used both approaches...

Data from: Temperature niche shift observed in a Lepidoptera population under allochronic divergence

Helena Santos, Maria Rosa Paiva, Catarina Tavares, Carole Kerdelhué & Manuela Branco
A process of adaptive divergence for tolerance to high temperatures was identified by using a rare model-system, consisting of two sympatric populations of a Lepidoptera (Thaumetopoea pityocampa) with different life-cycle timings, a "mutant" population with summer larval development, Leiria SP, and the founder natural population, having winter larval development, Leiria WP. A third, allopatric population (Bordeaux WP) was also studied. First and second instar larvae were experimentally exposed to daily-cycles of heat treatment reaching maximum...

Data from: Genetic footprints of Iberian cattle in America 500 years after the arrival of Columbus

Amparo M. Martínez, Luis T. Gama, Javier Cañón, Catarina Ginja, Juan V. Delgado, Susana Dunner, Vincenzo Landi, Inmaculada Martín-Burriel, M. Cecilia T. Penedo, Clementina Rodellar, Jose Luis Vega-Pla, Atzel Acosta, Luz Ángela Álvarez, Esperanza Camacho, Óscar Cortés, José Ribamar Marques, Óscar Roberto Martínez, Rubén Darío Martínez, Lilia Melucci, Guillermo Martínez-Velázquez, Jose Ernesto Muñoz, Alicia Postiglioni, Jorge Quiroz, Philip Sponenberg, Odalys Uffo … & Ruben D. Martínez
BACKGROUND: American Creole cattle presumably descend from animals imported from the Iberian Peninsula during the period of colonization and settlement, through different migration routes, and may have also suffered the influence of cattle directly imported from Africa. The introduction of European cattle, which began in the 18th century, and later of Zebu from India, has threatened the survival of Creole populations, some of which have nearly disappeared or were admixed with exotic breeds. Assessment of...

Data from: Revisiting the measurement of anomie

Ali Teymoori, Jolanda Jetten, Brock Bastian, Amarina Ariyanto, Frédérique Autin, Nadia Ayub, Constantina Badea, Tomasz Besta, Fabrizio Butera, Rui Costa-Lopes, Lijuan Cui, Carole Fantini, Gillian Finchilesc, Lowell Gaertner, Mario Gollwitzer, Ángel Gómez, Roberto González, Ying Yi Hong, Dorthe Høj Jensen, Minoru Karasawa, Thomas Kessler, Olivier Klein, Marcus Lima, Tuuli Anna Mähönen, Laura Megevand … & Gillian Finchilescu
Sociologists coined the term "anomie" to describe societies that are characterized by disintegration and deregulation. Extending beyond conceptualizations of anomie that conflate the measurements of anomie as 'a state of society' and as a 'state of mind', we disentangle these conceptualizations and develop an analysis and measure of this phenomenon focusing on anomie as a perception of the 'state of society'. We propose that anomie encompasses two dimensions: a perceived breakdown in social fabric (i.e.,...

Data from: Keeping your options open: maintenance of thermal plasticity during adaptation to a stable environment

Inês Fragata, Miguel Lopes-Cunha, Margarida Bárbaro, Bárbara Kellen, Margarida Lima, Gonçalo Faria, Sofia G. Seabra, Mauro Santos, Pedro Simões & Margarida Maria Matos
Phenotypic plasticity may allow species to cope with environmental variation. The study of thermal plasticity and its evolution helps understanding how populations respond to variation in temperature. In the context of climate change, it is essential to realize the impact of historical differences in the ability of populations to exhibit a plastic response to thermal variation and how it evolves during colonization of new environments. We have analyzed the real-time evolution of thermal reaction norms...
