Data from: New species of Franchia and Protozigzagiceras (Ammonoidea, Middle Jurassic): the phyletic origin of Zigzagiceratinae

Sixto R. Fernandez-Lopez & Giulio Pavia
Three genera and seven species belonging to the subfamily Zigzagiceratinae (family Perisphinctidae) are described from the Lower Bathonian of France and Saudi Arabia. Intraspecific dimorphism is recognized. A revision of the genus Franchia proposed by Sturani (1967), based on the syntypes and new specimens from south-east France, is presented. Franchia arkelli Sturani, Franchia subalpina sp. nov., Protozigzagiceras torrensi (Sturani), Protozigzagiceras tethycum sp. nov., Protozigzagiceras flexum sp. nov. and Protozigzagiceras densum sp. nov. are described from...

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: Breeding bird species diversity across gradients of land use from forest to agriculture in Europe

Matti J. Koivula, Dan E. Chamberlain, Robert J. Fuller, Stephen C. F. Palmer, Attila Bankovics, Fintan Bracken, Tom Bolger, Eduardo De Juana, Marc Montadert, Renato Neves, Rui Rufino, Angel Sallent, Luís Lopes Da Silva, Pedro J. Leitão, Manfred Steffen & Allan D. Watt
Loss, fragmentation and decreasing quality of habitats have been proposed as major threats to biodiversity world-wide, but relatively little is known about biodiversity responses to multiple pressures, particularly at very large spatial scales. We evaluated the relative contributions of four landscape variables (habitat cover, diversity, fragmentation and productivity) in determining different components of avian diversity across Europe. We sampled breeding birds in multiple 1-km2 landscapes, from high forest cover to intensive agricultural land, in eight...

Data from: Speciation below ground: tempo and mode of diversification in a radiation of endogean ground beetles

Carmelo Andújar, Sergio Pérez-González, Paula Arribas, Juan P. Zaballos, Alfried P. Vogler & Ignacio Ribera
Dispersal is a critical factor determining the spatial scale of speciation, which is constrained by the ecological characteristics and distribution of a species' habitat and the intrinsic traits of species. Endogean taxa are strongly affected by the unique qualities of the below-ground environment and its effect on dispersal, and contrasting reports indicate either high dispersal capabilities favoured by small body size and mediated by passive mechanisms, or low dispersal due to restricted movement and confinement...

Data from: Combining correlative and mechanistic niche models with human activity data to elucidate the invasive potential of a sub-Antarctic insect

Luis Pertierra, Pedro Aragón, Miguel Olalla-Tarraga, Greta Vega, Grant Duffy, Pete Convey, Scott Hayward, Kevin Hughes & Jesamine Bartlett
Aim Correlative Species Distribution Models (SDMs) are subject to substantial spatio-temporal limitations when historical occurrence records of data-poor species provide incomplete and outdated information for niche modelling. Complementary mechanistic modelling techniques can, therefore, offer a valuable contribution to underpin more physiologically-informed predictions of biological invasions, the risk of which is often exacerbated by climate change. In this study we integrate physiological and human pressure data to address the uncertainties and limitations of correlative SDMs and...

Social norms and cultural diversity in the development of third-party punishment

Bailey House, Patricia Kanngiesser, H. Clark Barrett, Süheyla Yilmaz, Andrew Marcus Smith, Carla Sebastian-Enesco, Alejandro Erut & Joan Silk
Human cooperation is likely supported by our tendency to punish selfishness in others. Social norms play an important role in motivating third-party punishment, and also in explaining societal differences in prosocial behavior. However, there has been little work directly linking social norms to the development of third-party punishment across societies. In this study, we explored the impact of normative information on the development of third-party punishment in 603 children aged 4-14 years, across six diverse...

Climate change and maladaptive wing shortening in a long-distance migratory bird

Carolina Remacha Sebastián, César Rodríguez, Javier De La Puente & Javier Pérez-Tris
Contemporary phenotypic trends associated with global change are widely documented, but whether such trends always denote trait optimization under changed conditions remains obscure. Natural selection has shaped the wings of long-distance migratory birds to minimize the costs of transport, and new optimal wing shapes could be promoted by migration patterns altered due to global change. Alternatively, wing shape could vary as a correlated response to selection on other traits favoured in a changing environment, eventually...

The role of plant-pollinator interactions in structuring nectar microbial communities

Clara De Vega, Sergio Álvarez-Pérez, Rafael G. Albaladejo, Sandy-Lynn Steenhuisen, Marc-André Lachance, Steve D. Johnson & Carlos M. Herrera
1. Floral nectar harbours a diverse microbiome of yeasts and bacteria that depend predominantly on animal visitors for their dispersal. Since pollinators visit specific sets of flowers and carry their own unique microbiota, we hypothesize that plant species visited by the same set of pollinators may support non-random nectar microbial communities linked together by the type of pollinator. 2. Here we explore the importance of plant-pollinator interactions in the assembly of nectar microbiome and study...

Data from: A phylogenetic study to assess the link between biome specialisation and diversification in swallowtail butterflies

Sara Gamboa, Fabien L. Condamine, Juan L. Cantalapiedra, Sara Varela, Jonathan Pelegrín, Iris Menéndez, Fernando Blanco & Manuel Hernández Fernández
The resource-use hypothesis, proposed by E.S. Vrba, states that habitat fragmentation caused by climatic oscillations would affect particularly biome specialists (species inhabiting only one biome), which might show higher speciation and extinction rates than biome generalists. If true, lineages would accumulate biome-specialist species. This effect would be particularly exacerbated for biomes located at the periphery of the global climatic conditions, namely, biomes that have high/low precipitation and high/low temperature such as rainforest (warm-humid), desert (warm-dry),...

Data from: Ecological specialization, rather than the island effect, explains morphological diversification in an ancient radiation of geckos

Héctor Tejero-Cicuéndez, Marc Simó-Riudalbas, Iris Menéndez & Salvador Carranza
Island colonists are often assumed to experience higher levels of phenotypic diversification than continental taxa. However, empirical evidence shows that exceptions to this “island effect” do exist. Here, we tested this pattern using a thoroughly sampled continent-island system, the genus Pristurus, a group of sphaerodactylid geckos distributed across continental Arabia and Africa and the Socotra Archipelago. We used a recently published phylogeny and an extensive morphological dataset to explore whether Socotran and continental taxa differ...

Data from: Diverse guilds provide complementary dispersal services in a woodland expansion process after land abandonment

Gema Escribano-Avila, María Calviño-Cancela, Beatriz Pías, Emilio Virgós, Fernando Valladares & Adrián Escudero
1. Land abandonment due to increasing depopulation of rural areas is an ongoing trend in developed countries worldwide. Abandoned lands represent an opportunity for ecosystem recovery, an urgent need for biodiversity conservation. Seed dispersal services provided by animals are a key feature for this process. Different dispersers may differentially contribute to plant recruitment under different ecological conditions, leading to complementary dispersal services. 2. We studied the dispersal services, quantified as the contribution to plant recruitment,...

Data from: The interplay among acorn abundance and rodent behavior drives the spatial pattern of seedling recruitment in mature Mediterranean oak forests

Pau Sunyer, Ester Boixadera, Alberto Muñoz, Raúl Bonal & Josep Maria Espelta
The patterns of seedling recruitment in animal-dispersed plants result from the interactions among environmental and behavioral variables. However, we know little on the contribution and combined effect of both kinds of variables. We designed a field study to assess the interplay between environment (vegetation structure, seed abundance, rodent abundance) and behavior (seed dispersal and predation by rodents, and rooting by wild boars), and their contribution to the spatial patterns of seedling recruitment in a Mediterranean...

Data from: Ecomorphological adaptation in three mudskippers (Teleostei: Gobioidei: Gobiidae) from the Persian Gulf and the Gulf of Oman

Gianluca Polgar, Mehdi Ghanbarifardi, Salvatore Milli, Ainhoa Agorreta, Mansour Aliabadian, Hamid Reza Esmaeili & Tsung Fei Khang
We hypothesise that the body shapes of three mudskipper species (Boleophthalmus dussumieri, Periophthalmus waltoni, and Scartelaos tenuis) are ecomorphological adaptations to different epi- and infaunal habitats. We investigated: (i) the association between burrow density and selected ecological variables; (ii) the phylogenetic relationships among these species, based on two mtDNA and one nDNA markers; (iii) their geometric morphometrics and ancestral shape reconstructions, based on two-dimensional landmark configurations; and (iv) their body surface-to-volume ratios (SAV), based on...

Data from: A temporal banding approach for consistent taxonomic ranking above the species level

Ekaphan Kraichak, Ana Crespo, Pradeep K. Divakar, Steven D. Leavitt & H. Thorsten Lumbsch
Comparable taxonomic ranks within clades can facilitate more consistent classifications and objective comparisons among taxa. Here we use a temporal approach to identify taxonomic ranks. This is an extension of the temporal banding approach including a Temporal Error Score that finds an objective cut-off for each taxonomic rank using information for the current classification. We illustrate this method using a data set of the lichenized fungal family Parmeliaceae. To assess its performance, we simulated the...

The interplay of wind and uplift facilitates over-water flight in facultative soaring birds

Elham Nourani, Gil Bohrer, Paolo Becciu, Richard O Bierregaard, Olivier Duriez, Jordi Figuerola, Laura Gangoso, Sinos Giokas, Hiroyoshi Higuchi, Christina Kassara, Olga Kulikova, Nicolas Lecomte, Flavio Monti, Ivan Pokrovsky, Andrea Sforzi, Jean-François Therrien, Nikos Tsiopelas, Wouter MG Vansteelant, Duarte S Viana, Noriyuki M Yamaguchi, Martin Wikelski & Kamran Safi
Flying over the open sea is energetically costly for terrestrial birds. Despite this, over-water journeys of many birds, sometimes hundreds of kilometers long, are uncovered by bio-logging technology. To understand how these birds afford their flights over the open sea, we investigated the role of atmospheric conditions, specifically wind and uplift, in subsidizing over-water flight at the global scale. We first established that ∆T, the temperature difference between sea surface and air, is a meaningful...

Deep vicariance and frequent transoceanic dispersal shape the evolutionary history of a globally distributed fern family

Weston Testo, Andre Gasper, Sonia Molino, José María Gabriel Y Galán, Alexandre Salino, Vinícius Dittrich & Emily Sessa
Premise Historical biogeography of ferns is typically expected to be dominated by long-distance dispersal, due to their minuscule spores. However, few studies have inferred the historical biogeography of a large and widely distributed group of ferns to test this hypothesis. Our aims are to determine the extent to which long-distance dispersal vs. vicariance have shaped the history of the fern family Blechnaceae, to explore ecological correlates of dispersal and diversification, and to determine whether these...

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: Congruent phylogenetic and fossil signatures of mammalian diversification dynamics driven by tertiary abiotic change

Juan López Cantalapiedra, Manuel Hernández Fernández, Beatriz Azanza & Jorge Morales
Computational methods for estimating diversification rates from extant species phylogenetic trees have become abundant in evolutionary research. However, little evidence exists about how their outcome compares to a complementary and direct source of information: the fossil record. Furthermore, there is virtually no direct test for the congruence of evolutionary rates based on these two sources. This task is only achievable in clades with both a well-known fossil record and a complete phylogenetic tree. Here, we...

Data from: Carnivoran resource and habitat use in the context of a Late Miocene faunal turnover episode

Laura Domingo, M. Soledad Domingo, Paul L. Koch, Jorge Morales & M. Teresa Alberdi
We investigate resource and habitat use by apex predators through stable isotope analysis at two Spanish Late Miocene localities: Los Valles de Fuentidueña (~9.6 Ma, LVF) and Cerro de los Batallones (~9.1 Ma, BAT). The temporal window represented by LVF and BAT was crucial in the shaping of the current Iberian mammalian structure because it corresponds to the initial stages of a faunal turnover episode and regional environmental change at ~9.5–8.5 Ma (Vallesian–Turolian transition), associated...

Data from: Distribution and functionality of copy number variation across European cattle populations

Maulik Upadhyay, Vinicius H. Da Silva, Hendrik-Jan Megens, Marleen H. P. W. Visker, Paolo Ajmone-Marsan, Valentin A. Bâlteanu, Susana Dunner, Jose Fernando Garcia, Catarina Ginja, Juha Kantanen, Martien A.M. Groenen, Richard P.M.A. Crooijmans, Vinicus H. Da Silva, Martien A. M. Groenen & Richard P. M. A. Crooijmans
Copy number variation (CNV), which is characterized by large-scale losses or gains of DNA fragments, contributes significantly to genetic and phenotypic variation. Assessing CNV across different European cattle populations might reveal genetic changes responsible for phenotypic differences, which have accumulated throughout the domestication history of cattle as consequences of evolutionary forces that act upon them. To explore pattern of CNVs across European cattle, we genotyped 149 individuals, that represent different European regions, using the Illumina...

Data from: Genome-wide signals of drift and local adaptation during rapid lineage divergence in a songbird

Guillermo Friis, Guillermo Fandos, Amanda J. Zellmer, John E. McCormack, Brant C. Faircloth & Borja Milá
The formation of independent evolutionary lineages involves neutral and selective factors, and understanding their relative roles in population divergence is a fundamental goal of speciation research. Correlations between allele frequencies and environmental variability can reveal the role of selection, yet the relative contribution of drift can be difficult to establish. Recently diversified taxa like the Oregon junco (Aves, Passerellidae, Junco hyemalis oreganus) of western North America provide ideal scenarios to apply genetic-environment association analyses (GEA)...

Data from: Mechanical and structural adaptations to migration in the flight feathers of a Palaearctic passerine

Iván De La Hera, Irene Hernández-Téllez, José Pérez-Rigueiro, Javier Pérez-Tris, Francisco Rojo & José Luis Tellería
Current avian migration patterns in temperate regions have been developed during the glacial retreat and subsequent colonization of the ice-free areas during the Holocene. This process resulted in a geographic gradient of greater seasonality as latitude increased that favoured migration-related morphological and physiological (co)adaptations. Most evidence of avian morphological adaptations to migration comes from the analysis of variation in the length and shape of the wings, but the existence of intra-feather structural adjustments has been...

Endocannabinoid signalling in stem cells and cerebral organoids drives differentiation to deep layer projection neurons via CB1 receptors

Juan Paraiso-Luna, Jose Aguareles, Ricardo Martin, Ane C. Ayo-Martin, Daniel Garcia-Rincon, Samuel Simon-Sanchez, Adan De Salas-Quiroga, Javier Diaz-Alonso, Elena Garcia-Taboada, Isabel Liste, Jose Sanchez-Prieto, Silvia Cappello, Manuel Guzman, Ismael Galve-Roperh & Carlos Costas-Insua
The endocannabinoid (eCB) system, via cannabinoid CB1 receptor, regulates neurodevelopment by controlling neural progenitor proliferation and neurogenesis. CB1 receptor signalling in vivo drives corticofugal deep layer projection neuron development through the regulation of BCL11B and Satb2 transcription factors. Here, we investigated the role of eCB signalling in mouse pluripotent embryonic stem cell-derived neuronal differentiation. Characterization of the eCB system revealed increased expression of eCB-metabolizing enzymes, eCB ligands and CB1 receptors along neuronal differentiation. CB1 receptor...
