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,...

Data from: Hybridization patterns between two marine snails, Littorina fabalis and L. obtusata

Diana Costa, Graciela Sotelo, Antigoni Kaliontzopoulou, João Carvalho, Roger Butlin, Johan Hollander & Rui Faria
Characterizing the patterns of hybridization between closely related species is crucial to understand the role of gene flow in speciation. In particular, systems comprising multiple contacts between sister species offer an outstanding opportunity to investigate how reproductive isolation varies with environmental conditions, demography and geographic contexts of divergence. The flat periwinkles, Littorina obtusata and L. fabalis (Gastropoda), are two intertidal sister species with marked ecological differences compatible with late stages of speciation. Although hybridization between...

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...

Data from: Unraveling conflicting density- and distance-dependent effects on plant reproduction using a spatially-explicit approach

José M. Fedriani, Thorsten Wiegand, Gemma Calvo, Alberto Suárez-Esteban, Miguel Jácome, Magdalena Żywiec & Miguel Delibes
1. Density- and distance-dependent (DDD) mechanisms are important determinants of plant reproductive success (PRS). Different components of sequential PRS can operate either in the same or in different directions and thus reinforce or neutralize each other, and they may also operate at different spatial scales. Thus, spatially-explicit approaches are needed to detect such complex DDD effects across multiple PRS components and spatial scales. 2. To reveal DDD effects of different components of early PRS of...

Data from: Tropical specialist versus climate generalist: diversification and demographic history of sister species of Carlia skinks from northwestern Australia

Ana Catarina Afonso Silva, Jason G. Bragg, Sally Potter, Carlos Fernandes, Maria Manuela Coelho & Craig Moritz
Species endemic to the tropical regions are expected to be vulnerable to future climate change due in part to their relatively narrow climatic niches. In addition, these species are more likely to have responded strongly to past climatic change, and this can be explored through phylogeographic analyses. To test the hypothesis that tropical specialists are more sensitive to climate change than climate generalists, we generated and analyze sequence data from mtDNA and ~2500 exons to...

Data from: Evidence for low-level hybridization between two allochronic populations of the pine processionary moth, Thaumetopoea pityocampa (Lepidoptera: Notodontidae)

Christian Burban, Mathieu Gautier, Raphael Leblois, Julie Landes, Helena Santos, Maria-Rosa Païva, Manuela Branco & Carole Kerdelhué
Divergence between populations sharing the same habitat can be initiated by different reproductive times, leading to allochronic differentiation. A spatially localized allochronic summer population (SP) of the pine processionary moth Thaumetopoea pityocampa, recently discovered in Portugal, occurs in sympatry with the local winter population (WP). We examined the level of genetic differentiation between the two populations and estimated the current gene flow within the spatial framework of their co-occurrence. Mitochondrial data indicated that the two...

Data from: The population genomics of archaeological transition in west Iberia: investigation of ancient substructure using imputation and haplotype-based methods

Rui Martiniano, Lara M. Cassidy, Ros Ó'Maoldúin, Russell McLaughlin, Nuno M. Silva, Licinio Manco, Daniel Fidalgo, Tania Pereira, Maria J. Coelho, Miguel Serra, Joachim Burger, Rui Parreira, Elena Moran, Antonio C. Valera, Eduardo Porfirio, Rui Boaventura, Ana M. Silva & Daniel G. Bradley
We analyse new genomic data (0.05–2.95x) from 14 ancient individuals from Portugal distributed from the Middle Neolithic (4200–3500 BC) to the Middle Bronze Age (1740–1430 BC) and impute genomewide diploid genotypes in these together with published ancient Eurasians. While discontinuity is evident in the transition to agriculture across the region, sensitive haplotype-based analyses suggest a significant degree of local hunter-gatherer contribution to later Iberian Neolithic populations. A more subtle genetic influx is also apparent in...

Data from: Climate and anthropogenic factors determine site occupancy in Scotland's Northern-range badger population: implications of context-dependent responses under environmental change

André P. Silva, Gonçalo Curveira-Santos, Kerry Kilshaw, Chris Newman, David W. Macdonald, Luciana G. Simões & Luís M. Rosalino
Aim In the light of human-induced rapid environmental change (HIREC), populations are exposed to ever-greater bioclimatic stress at the edge of a species’ historic range. The distribution dynamics of European badgers (Meles meles) at their southern edge are linked tightly to climatic variability. We contribute critical data on how climatic context and local factors determine site occupancy in a northern-range population. Location Eleven study areas (averaging ~21.3 km2) spread over ~50,000 km2 in Northern Scotland....

Data from: Functional anatomy of the cervical region in the late Miocene amphicyonid Magericyon anceps (Carnivora, Amphicyonidae): implications for its feeding behaviour

Gema Siliceo, Manuel J. Salesa, Mauricio Antón, Stéphane Peigné & Jorge Morales
We describe the skull and neck morphology of the late Miocene amphicyonid Magericyon anceps, focusing on aspects related to functional anatomy. This species, recorded only from the Vallesian sites of Batallones-1 and Batallones-3 (Madrid, Spain), is the last known amphicyonid in the fossil record of Western Europe, with the Batallones populations being one of the best-known of the family. The morphology of its skull and cervical vertebrae allows us to infer aspects of its associated...

Data from: Carcharodontosaurian remains (Dinosauria, Theropoda) from the Upper Jurassic of Portugal

Elisabete Malafaia, Pedro Mocho, Fernando Escaso, Pedro Dantas & Francisco Ortega
A new specimen of a theropod dinosaur found in the Upper Jurassic (Freixial Formation, late Tithonian) of the Lusitanian Basin is described. It corresponds to a single individual and includes a sequence of articulated caudal vertebrae, an almost complete right pes, and other fragments of the appendicular skeleton. The specimen includes the most complete pes of a theropod dinosaur currently known in the Lusitanian Basin and represents one of the youngest skeletal records of theropod...

Data from: Quantifying in situ phenotypic variability in the hydraulic properties of four tree species across their distribution range in Europe

Sylvain Delzon, N. González-Muñoz, J. M. Torres-Ruiz, G. Capdeville, F. Sterck, P. Copini, G. Petit, G. Von Arx, A. Lintunen, L. Grönlund, T. Hölttä, M. C. Caldeira, R. Lobo-Do-Vale & M. Peltoniemi
Many studies have reported that hydraulic properties vary considerably between tree species, but little is known about their intraspecific variation and, therefore, their capacity to adapt to a warmer and drier climate. Here, we quantify phenotypic divergence and clinal variation for embolism resistance, hydraulic conductivity and branch growth, in four tree species, two angiosperms (Betula pendula, Populus tremula) and two conifers (Picea abies, Pinus sylvestris), across their latitudinal distribution in Europe. Growth and hydraulic efficiency...

Data from: Population divergence with or without admixture: selecting models using an ABC approach

Vitor C. Sousa, Mark A. Beaumont, Pedro Fernandes, Maria M. Coelho & Lounès Chikhi
Genetic data have been widely used to reconstruct the demographic history of populations, including the estimation of migration rates, divergence times and relative admixture contribution from different populations. Recently, increasing interest has been given to the ability of genetic data to distinguish alternative models. One of the issues that has plagued this kind of inference is that ancestral shared polymorphism is often difficult to separate from admixture or gene flow. Here, we applied an Approximate...

Data from: Host-jump drives rapid and recent ecological speciation of the emergent fungal pathogen Colletotrichum kahawae

Diogo N. Silva, Pedro Talhinhas, Cai Lei, Luzolo Manuel, Elijah K. Gichuru, Andreia Loureiro, Vítor Várzea, Octavio S. Paulo & Dora Batista
Ecological speciation through host-shift has been proposed as a major route for the appearance of novel fungal pathogens. The growing awareness of their negative impact on global economies and public health created an enormous interest in identifying the factors that are most likely to promote their emergence in nature. In this work, a combination of pathological, molecular and geographic data was used to investigate the recent emergence of the fungus Colletotrichum kahawae (Ck). Ck emerged...

Data from: Origin of the chromosomal radiation of Madeiran house mice: a microsatellite analysis of metacentric chromosomes

Maria Da Luz Mathias, Janice Britton-Davidian, Jeremy B. Searle & Daniel W. Förster
Chromosome races of Mus musculus domesticus are characterised by particular sets of metacentric chromosomes formed by Robertsonian fusions and whole-arm reciprocal translocations. The Atlantic island of Madeira is inhabited by six chromosome races of house mice with 6–9 pairs of metacentric chromosomes. Three of these races are characterised by the metacentric 3.8 also found elsewhere in the distribution of M. m. domesticus, including Denmark and Spain. We investigated the possibility that metacentric 3.8 was introduced...

Data from: Positive epistasis drives the acquisition of multidrug resistance.

Sandra Trindade, Ana Sousa, Karina Bivar Xavier, Francisco Dionisio, Miguel Godinho Ferreira & Isabel Gordo
The evolution of multiple antibiotic resistance is an increasing global problem. Resistance mutations are known to impair fitness, and the evolution of resistance to multiple drugs depends both on their costs individually and on how they interact—epistasis. Information on the level of epistasis between antibiotic resistance mutations is of key importance to understanding epistasis amongst deleterious alleles, a key theoretical question, and to improving public health measures. Here we show that in an antibiotic-free environment...

Data from: Influences of past climatic changes on historical population structure and demography of a cosmopolitan marine predator, the common dolphin (genus Delphinus)

Ana Amaral, Luciano Beheregaray, Kerstin Bilgmann, Luís Freitas, Kelly Robertson, Marina Sequeira, Karen Stockin, M. M. Coelho & Luciana Möller
Climatic oscillations during the Pleistocene have greatly influenced the distribution and connectivity of many organisms, leading to extinctions but also generating biodiversity. While the effects of such changes have been extensively studied in the terrestrial environment, studies focusing on the marine realm are still scarce. Here we used sequence data from one mitochondrial and five nuclear loci to assess the potential influence of Pleistocene climatic changes on the phylogeography and demographic history of a cosmopolitan...

Data from: Introgressive hybridization as a promoter of genome reshuffling in natural homoploid fish hybrids (Cyprinidae, Leuciscinae)

Carla S. A. Pereira, Maria Ana Aboim, Petr Ráb & Maria João Collares-Pereira
Understanding the mechanisms underlying diversification and speciation by introgressive hybridization is currently one of the major challenges in evolutionary biology. Here, the analysis of hybridization between two pairs of Iberian Leuciscinae provided new data on independent hybrid zones involving Achondrostoma oligolepis (AOL) and Pseudochondrostoma duriense (PDU), and confirmed the occurrence of hybrids between AOL and Pseudochondrostoma polylepis (PPO). A multilevel survey combining morphological, genetic and cytogenomic markers on a vast population screening successfully sorted 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: Large birds travel farther in homogeneous environments

Marlee A. Tucker, Olga Alexandrou, , Keith L. Bildstein, Katrin Böhning-Gaese, Chloe Bracis, John N. Brzorad, Evan R. Buechley, David Cabot, Justin M. Calabrese, Carlos Carrapato, André Chiaradia, Lisa C. Davenport, Sarah C. Davidson, Mark Desholm, Christopher R. DeSorbo, Robert Domenech, Peter Enggist, William F. Fagan, Nina Farwig, Wolfgang Fiedler, Christen H. Fleming, Alastair Franke, John M. Fryxell, Clara García-Ripollés … & João Paulo Silva
Aim: Animal movement is an important determinant of individual survival, population dynamics, and ecosystem structure and function. Yet it is still unclear how local movements are related to resource availability and the spatial arrangement of resources. Using resident bird species and migratory bird species outside of the migratory period, we examined how the distribution of resources affect the movement patterns of both large terrestrial birds (e.g., raptors, bustards, hornbills) and waterbirds (e.g., cranes, storks, ducks,...

Data from: Effect of cadmium accumulation on the performance of plants and of herbivores that cope differently with organic defenses

Diogo Prino Godinho, Helena Cristina Serrano, Anabela B. Da Silva, Cristina Branquinho & Sara Magalhães
Some plants are able to accumulate in their shoots metals at levels that are toxic to most other organisms. This ability may serve as a defence against herbivores. Therefore, both metal-based and organic defences may affect herbivores. However, how metal accumulation affects the interaction between herbivores and organic plant defences remains overlooked. To fill this gap, we studied the interactions between tomato (Solanum lycopersicum), a model plant that accumulates cadmium, and two spidermite species, Tetranychus...
