A Escola Normal de Lisboa e a formação de professores: percursos, identidade e afirmação sob o signo da pedagogia republicana da educação nova

Maria João Mogarro
A Escola Normal de Lisboa representa um símbolo maior da formação de professores, nomeadamente durante o período republicano (1910-1926), em que se registou um investimento significativo na formação de professores, tanto ao nível do discurso político e educativo, como no esforço reformista. O ensino normal conheceu então a sua fase de apogeu, pela importância que foi atribuída à formação de docentes, fundamental na conceção da educação como motor do desenvolvimento e progresso do país, assim...

eDNA in a bottleneck: obstacles to fish metabarcoding studies in megadiverse freshwater systems

Jake Jackman, Chiara Benvenuto, Ilaria Coscia, Cintia Carvalho, Jonathan Ready, Jean Boubli, William Magnusson, Allan McDevitt & Naiara Sales
The current capacity of environmental DNA (eDNA) to provide accurate insights into the biodiversity of megadiverse regions (e.g., the Neotropics) requires further evaluation to ensure its reliability for long-term monitoring. In this study, we first evaluated the taxonomic resolution capabilities of a short fragment from the 12S rRNA gene widely used in fish eDNA metabarcoding studies, and then compared eDNA metabarcoding data from water samples with traditional sampling using nets. For the taxonomic discriminatory power...

Utilizing field collected insects for next generation sequencing: effects of sampling, storage, and DNA extraction methods

Kimberly Ballare, Nathaniel Pope, Antonio Castilla, Sarah Cusser, Richard Metz & Shalene Jha
DNA sequencing technologies continue to advance the biological sciences, expanding opportunities for genomic studies of non-model organisms for basic and applied questions. Despite these opportunities, many next-generation sequencing protocols have been developed assuming a substantial quantity of high molecular weight DNA (>100 ng), which can be difficult to obtain for many study systems. In particular, the ability to sequence field-collected specimens that exhibit varying levels of DNA degradation remains largely unexplored. In this study we...

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...

Social learning by mate-choice copying increases dispersal and reduces local adaptation

Manuel Sapage, Susana A. M. Varela & Hanna Kokko
1. In heterogeneous environments, dispersal may be hampered not only by direct costs, but also because immigrants may be locally maladapted. While maladaptation affects both sexes, this cost may be modulated in females if they express mate preferences that are either adaptive or maladaptive in the new local population. 2. Dispersal costs under local adaptation may be mitigated if it is possible to switch to expressing traits of locally adapted residents. In a sexual selection...

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...

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: Mate choice driven by genome in an allopolyploid fish complex

Miguel Morgado-Santos, Maria Filomena Magalhães, Luís Vicente & Maria João Collares-Pereira
Nonsexual complexes which lack typical reproductive isolation and show multiple conspecific and heterospecific mating options among hybrids and parental species are excellent models to study mate choice based on genetics. The allopolyploid fish complex Squalius alburnoides includes multiple fertile male and female genomotypes reproducing among each other and with the sympatric species of the Squalius genus. We used this hybridogenetic complex to study the relationship between mate preference and mates’ genetic background, focusing on a...

William Douglas De Carvalho, Mayara A. Martins, Carlos Eduardo L. Esbérard & Jorge M. Palmeirim
Aim: This study aims to contribute to the identification of ecological determinants of tropical moist forest montane biodiversity, analyzing changes in the structure of bat assemblages along an elevational gradient and testing the role of species traits shaping those assemblages. Location: Mountain ranges in the Brazilian Atlantic Forest. Methods: We compiled a dataset with the composition of phyllostomid bat assemblages at 32 forested sites, ranging from 60m to 1960m a.s.l. We quantified how abundance and...

The sources of variation for individual prey-to-predator size ratios

Jorge Henriques, Mariángeles Lacava, Celeste Guzman, Maria Pilar Gavín-Centol, Dolores Ruiz-Lupión, Eva De Mas, Sara Magalhães & Jordi Moya-Laraño
The relative body size at which predators are willing to attack prey, a key trait for predator-prey interactions, is usually considered invariant. However, this ratio can vary widely among individuals or populations. Identifying the range and origin of such variation is key to understanding the strength and constraints on selection in both predators and prey. Still, these sources of variation remain largely unknown. We filled this gap by measuring the genetic, maternal and environmental variation...

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,...

Explaining illness with evil: Pathogen prevalence fosters moral vitalism

Brock Bastian, Christin-Melanie Vauclair, Steve Loughnan, Paul Bain, Ashwini Ashokkumar, Maja Becker, Michal Bilewicz, Emma Collier-Baker, Carla Crespo, Paul W. Eastwick, Ronald Fischer, Malte Friese, Ángel Gómez, Valeschka M. Guerra, Jose Luis Castellanos Guevara, Katja Hanke, Nic Hooper, Li-Li Huang, Shi Junqi, Minoru Karasawa, Peter Kuppens, Siri Leknes, Müjde Peker, Cesar Pelay, Afoditi Pina … & William B. Swann
Pathogens represent a significant threat to human health leading to the emergence of strategies designed to help manage their negative impact. We examined how spiritual beliefs developed to explain and predict the devastating effects of pathogens and spread of infectious disease. Analysis of existing data in Studies 1 and 2 suggests that moral vitalism (beliefs about spiritual forces of evil) is higher in geographical regions characterized by historical higher levels of pathogens. Furthermore, drawing on...

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...

A total of 9,966 high quality transcriptome contigs were assembled, from which 951 putative SNPs were discovered. In all, 479 putative SNPs and 1,624 simple sequence repeats (SSRs) suitable for genotyping were identified. A subset of 96 was selected for genotyping; from these, 80 SNPs were considered polymorphic...

Data from: Drosophila melanogaster larvae make nutritional choices that minimize developmental time

Marisa A. Rodrigues, Nelson E. Martins, Lara F. Balancé, Lara N. Broom, António J. S. Dias, Ana S. D. Fernandes, Fábio Rodrigues, Élio Sucena & Christen K. Mirth
Organisms from slime moulds to humans carefully regulate their macronutrient intake to optimize a wide range of life history characters including survival, stress resistance, and reproductive success. However, life history characters often differ in their response to nutrition, forcing organisms to make foraging decisions while balancing the trade-offs between these effects. To date, we have a limited understanding of how the nutritional environment shapes the relationship between life history characters and foraging decisions. To gain...

Data from: Riparian plant guilds become simpler and most likely fewer following flow regulation

María D. Bejarano, Christer Nilsson & Francisca C. Aguiar
1. River regulation affects riparian systems worldwide and conservation and restoration efforts are essential to retain biodiversity, and the functioning and services of riverine ecosystems. Effects of regulation on plant species richness have been widely addressed, but the filtering effect of regulation on guilds has received less attention. 2. We used a functional trait approach to identify adaptive plant strategies through regulation-tolerant traits and predict shifts of riparian vegetation communities in response to regulation. We...

Data from: Anthropogenic disturbance of tropical forests threatens pollination services to açaí palm in the Amazon river delta

Alistair John Campbell, Luísa Gigante Carvalheiro, Marcia Motta Maués, Rodolfo Jaffé, Tereza Cristina Giannini, Madson Antonio Benjamin Freitas, Beatriz Woiski Texeira Coelho & Cristiano Menezes
The açaí palm Euterpe oleracea Mart. in the Amazon river delta has seen rapid expansion to meet increased demand for its fruit. This has been achieved by transforming lowland forest habitats (floodplains) into simplified agroforests and intensive plantation in upland areas. As açaí palm makes an important contribution to the economy and food security of local communities, identifying management approaches that support biodiversity and ecosystem processes that underpin fruit production on açaí farms is essential....

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...

Data from: Conservation priorities of Iberoamerican pig breeds and their ancestors based on microsatellite information

Criollo pig breeds are descendants from pigs brought to the American continent starting with Columbus second trip in 1493. Pigs currently play a key role in social economy and community cultural identity in Latin America. The aim of this study was to establish conservation priorities among a comprehensive group of Criollo pig breeds based on a set of 24 microsatellite markers and using different criteria. Spain and Portugal pig breeds, wild boar populations of different...

Data from: History, geography, and host use shape genome-wide patterns of genetic variation in the redheaded pine sawfly (Neodiprion lecontei)

Robin K. Bagley, Vitor C. Sousa, Matthew L. Niemiller & Catherine R. Linnen
Divergent host use has long been suspected to drive population differentiation and speciation in plant-feeding insects. Evaluating the contribution of divergent host use to genetic differentiation can be difficult, however, as dispersal limitation and population structure may also influence patterns of genetic variation. In this study, we use double-digest restriction-associated DNA (ddRAD) sequencing to test the hypothesis that divergent host use contributes to genetic differentiation among populations of the redheaded pine sawfly (Neodiprion lecontei), a...

Data from: Using beta diversity to inform agricultural policies and conservation actions on Mediterranean farmland

Joana Santana, Miguel Porto, Luis Reino, Francisco Moreira, Paulo Flores Ribeiro, José Lima Santo, John T. Rotenberry & Pedro Beja
1. Spatial variation in species composition (β-diversity) is an important component of farmland biodiversity, which together with local richness (α-diversity) drives the number of species in a region (γ-diversity). However, β-diversity is seldom used to inform conservation, due to limited understanding of its responses to agricultural management, and lack of clear links between β-diversity changes and conservation outcomes. 2. We explored the value of β-diversity to guide conservation on farmland, by quantifying the contribution of...
