Metabolic and behavioral adaptations of greater white-toothed shrews to urban conditions

Flávio Oliveira, Maria Mathias, Leszek Rychlik, Joaquim Tapisso & Sophie Von Merten
The global trend of urbanization is creating novel challenges to many animal species. Studies investigating behavioral differences between rural and urban populations often report a general increase in risk-taking behaviors in urban populations. According to the most common energy management model (the performance model), behaviors that increase access to resources, such as aggression and boldness, and behaviors that consume net energy, like locomotion and stress responses, are both positively correlated to resting metabolic rate (RMR)....

Timing uncertainty in collective risk dilemmas encourages group reciprocation and polarization

Elias Fernandez Domingos, Jelena Grujić, Francisco C. Santos, Juan C. Burguillo Rial, Georg Kirchsteiger, Francisco C. Santos & Tom Lenaerts
Social dilemmas are often shaped by actions involving uncertain returns only achievable in the future, such as climate action or voluntary vaccination. In this context, uncertainty may produce non-trivial effects. Here, we assess experimentally — through a collective risk dilemma — the effect of timing uncertainty, i.e. how uncertainty about when a target needs to be reached affects the participants’ behaviours. We show that timing uncertainty prompts not only early generosity but also polarised outcomes,...

Influence of preservation methods, sample medium and sampling time on eDNA recovery in a neotropical river

Naiara Sales, Owen S. Wangensteen, Daniel Carvalho & Stefano Mariani
Environmental DNA (eDNA) has rapidly emerged as a promising biodiversity monitoring technique, proving to be a sensitive and cost‐effective method for species detection. Despite the increasing popularity of eDNA, several questions regarding its limitations remain to be addressed. We investigated the effect of sampling me‐ dium and time, and preservation methods, on fish detection performance based on eDNA metabarcoding of neotropical freshwater samples. Water and sediment sam‐ ples were collected from 11 sites along the...

Ecological, genetic and evolutionary drivers of regional genetic differentiation in Arabidopsis thaliana

Xavier Picó, Antonio Castilla, Belen Mendez-Vigo, Arnald Marcer, Joaquin Martinez-Minaya, David Conesa & Carlos Alonso-Blanco
Background: Disentangling the drivers of genetic differentiation is one of the cornerstones in evolution. This is because genetic diversity, and the way in which it is partitioned within and among populations across space, is an important asset for the ability of populations to adapt and persist in changing environments. We tested three major hypotheses accounting for genetic differentiation—isolation-by-distance (IBD), isolation-by-environment (IBE) and isolation-by-resistance (IBR)—in the annual plant Arabidopsis thaliana across the Iberian Peninsula, the region...

Data from: Population-specific effect of Wolbachia on the cost of fungal infection in spider mites

Flore Zélé, Mustafa Altintas, Inês Santos, Ibrahim Cakmak & Sara Magalhães
Many studies have revealed the ability of the endosymbiotic bacterium Wolbachia to protect its arthropod hosts against diverse pathogens. However, as Wolbachia may also increase the susceptibility of its host to infection, predicting the outcome of a particular Wolbachia-host-pathogen interaction remains elusive. Yet, understanding such interactions and their eco-evolutionary consequences is crucial for disease and pest control strategies. Moreover, how natural Wolbachia infections affectartificially introduced pathogens for biocontrol has never been studied. Tetranychus urticae spider...

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...

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,...

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,...

Data from: Sex-specific telomere length and dynamics in relation to age and reproductive success in Cory’s Shearwaters

Christina Bauch, Marie Claire Gatt, José Pedro Granadeiro, Simon Verhulst & Paulo Catry
Individuals in free-living animal populations generally differ substantially in reproductive success, lifespan and other fitness-related traits and the molecular mechanisms underlying this variation are poorly understood. Telomere length and dynamics are candidate traits explaining this variation, as long telomeres predict a higher survival probability and telomere loss has been shown to reflect experienced “life stress”. However, telomere dynamics among very long-lived species are unresolved. Additionally, it is generally not well understood how telomeres relate with...

Genomics of population differentiation in humpback dolphins, Sousa spp. in the Indo-Pacific Ocean

Ana Rita Amaral, Cátia Chanfana, Brian Smith, Rubaiyat Mansur, Tim Collins, Robert Baldwin, Gianna Minton, Guido Parra, Michael Krutzen, Thomas Jefferson, Leszek Karczmarski, Almeida Guissamulo, & Howard Rosenbaum
Speciation is a fundamental process in evolution and crucial to the formation of biodiversity. It is a continuous and complex process, which can involve multiple interacting barriers leading to heterogeneous genomic landscapes with various peaks of divergence among populations. In this study, we used a population genomics approach to gain insights on the speciation process and to understand the population structure within the genus Sousa across its distribution in the Indo-Pacifc region. We found 5...

Data from: Marine regime shifts impact synchrony of deep‐sea fish growth in the Northeast Atlantic

Susanne E. Tanner, Eva Giacomello, Gui M. Menezes, Alice Mirasole, João Neves, Vera Sequeira, Rita P. Vasconcelos, Ana Rita Vieira & John R. Morrongiello
The complexity and spatio–temporal scale of populations’ dynamics influence how populations respond to large-scale ecological pressures. Detecting and attributing synchrony (i.e. temporally coincident fluctuations in populations’ parameters) is key as synchronous populations can become more vulnerable to stochastic events that can affect the viability of harvest and have profound consequences to community structure. Here, we aimed to estimate the level of synchrony in fish growth within and among species across 1 million km2 and identify...

Migrants and residents of a long-lived seabird differ in their behavioural response to a stressor

Marie Claire Gatt, José Pedro Granadeiro & Paulo Catry
Inter-individual variation in behaviour has been recognised as a major driver of population ecology, but its relationship to migratory strategy has been ill-explored. Here, we investigated whether male migrant and resident Cory’s Shearwaters (Calonectris borealis), a long-lived partially migratory seabird, are distinguishable by their temperament at the colony. We tracked a large number of individuals over two winters using GLS devices and assessed whether exploratory behaviour and reaction to extraction from the nest corresponded to...

Um símbolo da vontade republicana de reformar o ensino normal: o edifício da Escola Normal Primária de Lisboa

Carlos Manique da Silva
Durante o período da I República o esforço reformador na área da educação procurou situar-se numa dinâmica de rutura face aos últimos anos de Monarquia. Mas, como notou António Nóvoa (1989), trata-se de uma reação / oposição que não se funda, essencialmente, numa questão pedagógica. De facto, o olhar niilista para o passado monárquico – o “espírito de presente” orientado para um “horizonte de expetativa”, para adotarmos as expressões de Justino Magalhães (2012, p. 11)...

Estudo comparativo das representações maternas em díades com bebés de termo, pré-termo e extremo pré-termo

Ana Rita Almeida, Rute Casimiro, Sandra Antunes, Maria João Alves, Joana Lopes, Camila Ribeiro, Margarida Custódio dos Santos, João Moreira & Marina Fuertes
As representações das mães acerca dos seus bebés e da maternidade têm sido associadas à vinculação e ao desenvolvimento subsequente do bebé (e.g., Benoit, Parker, & Zeanah, 1997; Fuertes, Faria, Fink & Barbosa, 2011, Kochanska, 1998; Zeanah, Benoit, Hirshberg, Barton, & Regan, 1994). Deste modo, o estudo das representações maternas ganhou importância tanto no campo da investigação na área da relação mãe-filho(a) como na intervenção na maternidade de risco. No caso das mães dos bebés...

Bird communities in the Swiss Alps, 1999-2018, abundance data

Vicente García-Navas, Thomas Sattler, Hans Schmid & Arpat Ozgul
Aim: Mountains are biodiversity hotspots and are among the most sensitive eco- systems to ongoing global change being thus of conservation concern. Under this scenario, assessing how biological communities vary over time along elevational gra- dients and the relative effects of niche-based deterministic processes and stochastic events in structuring assemblages is essential. Here, we examined how the temporal trends of bird communities vary with elevation over a 20 year-period (1999–2018). We also tested for differences...

Heta Nääs, Noémie Ross, Frédéric Bouchard, Michelle Paquette, Audrey Veillette, Michael Fritz, Stefanie Weege, Julie Malenfant-Lepage, Bethany Deshpande, Alexander Nieuwendam, Ashley Rudy, Matthias Siewert, Ylva Sjöberg, Jonathan Harbor, J. Otto Habeck, Kerstin Krøier Rasmussen & Kirstey Langley
This project started in October 2015 with a crazy idea : prepare and submit a funding application for an international, multidisciplinary and non-traditional scientific outreach project… within the next 48 hours. Well, it worked out. A group of highly motivated young researchers from Canada and Europe united to combine arts and science and produce a series of outreach comic strips about permafrost (frozen ground). The aim of the project is to present and explain scientific...

Data from: Endosymbiont diversity in natural populations of Tetranychus mites is rapidly lost under laboratory conditions

Flore Zélé, Inês Santos, Margarida Matos, Mylène Weill, Fabrice Vavre & Sara Magalhães
Although the diversity of bacterial endosymbionts in arthropods is well documented, whether and how such diversity is maintained remains an open question. We investigated the temporal changes occurring in the prevalence and composition of endosymbionts after transferring natural populations of Tetranychus spider-mites from the field to the laboratory. These populations, belonging to three different Tetranychus species (T. urticae, T. ludeni and T. evansi) carried variable infection frequencies of Wolbachia, Cardinium, and Rickettsia. We report a...

Mobilisation of data to stakeholder communities: Bridging the research-practice gap using a commercial shellfish species model

Kate Mahony, Sarah Culloty, Alice Fitch, Sara Cabral, Mélanie Rocroy, Xavier De Montaudouin, Sharon Lynch, Sian Egerton & Luísa Magalhães
Knowledge mobilisation is required to “bridge the gap” between research, policy and practice. This activity is dependent on the amount, richness and quality of the data published. To understand the impact of a changing climate on commercial species, stakeholder communities require better knowledge of their past and current situations. The common cockle (Cerastoderma edule) is an excellent model species for this type of analysis, as it is well-studied due to its cultural, commercial and ecological...

Dominant native and non-native graminoids differ in key leaf traits irrespective of nutrient availability

Arthur Broadbent, Jennifer Firn, James McGree, Elizabeth Borer, Yvonne Buckley, W. Stanley Harpole, Kimberly Komatsu, Andrew MacDougall, Kate Orwin, Nicholas Ostle, Eric Seabloom, Jonathan Bakker, Lori Biedermann, Maria Caldeira, Nico Eisenhauer, Nicole Hagenah, Yann Hautier, Joslin Moore, Carla Nogueira, Pablo Peri, Anita Risch, Christiane Roscher, Martin Schuetz & Carly Stevens
Aim Nutrient enrichment is associated with plant invasions and biodiversity loss. Functional trait advantages may predict the ascendancy of invasive plants following nutrient enrichment but this is rarely tested. Here, we investigate 1) whether dominant native and non-native plants differ in important morphological and physiological leaf traits, 2) how their traits respond to nutrient addition, and 3) whether responses are consistent across functional groups. Location Australia, Europe, North America and South Africa Time period 2007...
