Data from: Extreme genetic structure in a social bird species despite high dispersal capacity

Francisco Morinha, José A. Dávila, Bastos Estela, João A. Cabral, Óscar Frías, José L. González, Paulo Travassos, Diogo Carvalho, Borja Milá & Guillermo Blanco
Social barriers have been shown to reduce gene flow and contribute to genetic structure among populations in species with high cognitive capacity and complex societies, such as cetaceans, apes and humans. In birds, high dispersal capacity is thought to prevent population divergence unless major geographic or habitat barriers induce isolation patterns by dispersal, colonization or adaptation limitation. We report that Iberian populations of the red-billed chough, a social, gregarious corvid with high dispersal capacity, show...

Data from: Host nest site choice depends on risk of cuckoo parasitism in magpie hosts

Mónica Expósito-Granados, Deseada Parejo, Juan Gabriel Martínez, Marta Precioso, Mercedes Molina-Morales & Jesús M. Avilés
Avian brood parasites impose large fitness costs on their hosts and, thus, brood parasitism has selected for an array of host defensive mechanisms to avoid them. So far most studies have focused on antiparasite defenses operating at the egg and chick stages and neglected defenses that may work prior to parasite egg deposition. Here, we experimentally explore the possibility that hosts, as part of a front-line defense, might minimize parasitism costs through informed nest site...

Data from: Agriculture shapes the trophic niche of a bat preying on multiple pest arthropods across Europe: evidence from DNA metabarcoding

Ostaizka Aizpurua, Ivana Budinski, Panagiotis Georgiakakis, Shyam Gopalakrishnan, Carlos Ibáñez, Vanessa Mata, Hugo Rebelo, Danilo Russo, Farkas Szodoray-Parádi, Violeta Zhelyazkova, Vida Zrncic, M. Thomas P. Gilbert & Antton Alberdi
The interaction between agricultural production and wildlife can shape, and even condition, the functioning of both systems. In this study we i) explored the degree to which a widespread European bat, namely the common bent-wing bat Miniopterus schreibersii, consumes crop-damaging insects at a continental scale, and ii) tested whether its dietary niche is shaped by the extension and type of agricultural fields. We employed a dual-primer DNA metabarcoding approach to characterise arthropod 16S and COI...

Christopher Stephen Bird, Ana Veríssimo, Sarah Magozzi, Kátya G. Abrantes, Alex Aguilar, Hassan Al-Reasi, Adam Barnett, Dana M. Bethea, Gérard Biais, Asuncion Borrell, Marc Bouchoucha, Mariah Boyle, Edward J. Brooks, Juerg Brunnschweiler, Paco Bustamante, Aaron Carlisle, Diana Catarino, Stéphane Caut, Yves Cherel, Tiphaine Chouvelon, Diana Churchill, Javier Ciancio, Julien Claes, Ana Colaço, Dean L. Courtney … & Clive N. Trueman
Sharks are a diverse group of mobile predators that forage across varied spatial scales and have the potential to influence food web dynamics. The ecological consequences of recent declines in shark biomass may extend across broader geographic ranges if shark taxa display common behavioural traits. By tracking the original site of photosynthetic fixation of carbon atoms that were ultimately assimilated into muscle tissues of 5,394 sharks from 114 species, we identify globally consistent biogeographic traits...

Data from: Immanent conditions determine imminent collapses: nutrient regimes define the resilience of macroalgal communities

Jordi Boada, Rohan Arthur, David Alonso, Jordi F. Pagès, Albert Pessarrodona, Silvia Oliva, Giulia Ceccherelli, Luigi Piazzi, Javier Romero & Teresa Alcoverro
Predicting where state-changing thresholds lie can be inherently complex in ecosystems characterized by nonlinear dynamics. Unpacking the mechanisms underlying these transitions can help considerably reduce this unpredictability. We used empirical observations, field and laboratory experiments, and mathematical models to examine how differences in nutrient regimes mediate the capacity of macrophyte communities to sustain sea urchin grazing. In relatively nutrient-rich conditions, macrophyte systems were more resilient to grazing, shifting to barrens beyond 1 800 g m−2...

Data from: Biological invasion modifies the co-occurrence patterns of insects along a stress gradient

José Antonio Carbonell, Josefa Velasco, Andres Millan, Andy J. Green, Cristina Coccia, Simone Guareschi & Cayetano Gutiérrez-Cánovas
Biological invasions have become one of the most important drivers of biodiversity loss and ecosystem change world-wide. However, it is still unclear how invasions may interact with local abiotic stressors, which are expected to increase as global change intensifies. Furthermore, we know little about the response to biological invasions of insects, despite their disproportionate contribution to global animal biodiversity. The aim of the present work is to investigate the impact of an invasive aquatic insect...

Data from: A father effect explains sex-ratio bias

Aurelio F. Malo, Felipe Martinez-Pastor, Francisco Garcia-Gonzalez, Julian Garde, Jonathan D. Ballou & Robert C. Lacy
Sex ratio allocation has important fitness consequences, and theory predicts that parents should adjust offspring sex ratio in cases where the fitness returns of producing male and female offspring vary. The ability of fathers to bias offspring sex ratios has traditionally been dismissed given the expectation of an equal proportion of X- and Y-chromosome-bearing sperm (CBS) in ejaculates due to segregation of sex chromosomes at meiosis. This expectation has been recently refuted. Here we used...

Data from: The shift from plant–plant facilitation to competition under severe water deficit is spatially explicit

Michael J. O'Brien, Francisco I. Pugnaire, Cristina Armas, Susana Rodríguez-Echeverría & Christian Schöb
The stress-gradient hypothesis predicts a higher frequency of facilitative interactions as resource limitation increases. Under severe resource limitation, it has been suggested that facilitation may revert to competition, and identifying the presence as well as determining the magnitude of this shift is important for predicting the effect of climate change on biodiversity and plant community dynamics. In this study, we perform a meta-analysis to compare temporal differences of species diversity and productivity under a nurse...

Data from: Contrasts in the marine ecosystem of two Macaronesian islands: a comparison between the remote Selvagens Reserve and Madeira Island

Alan M. Friedlander, Enric Ballesteros, Sabrina Clemente, Emanuel J. Gonçalves, Andrew Estep, Paul Rose & Enric Sala
The islands of Madeira and Selvagens are less than 300 km apart but offer a clear contrast between a densely populated and highly developed island (Madeira), and a largely uninhabited and remote archipelago (Selvagens) within Macaronesia in the eastern Atlantic. The Madeira Archipelago has ~260,000 inhabitants and receives over six million visitor days annually. The Selvagens Islands Reserve is one of the oldest nature reserves in Portugal and comprises two islands and several islets, including...

Data from: Trait-based selection of nurse plants to restore ecosystem functions in mine tailings

Jose A. Navarro Cano, Miguel Verdú & Marta Goberna
1.Metal mining in drylands generates waste tailings with high toxicity, physical instability, as well as water and thermal stresses, that hamper their biological colonisation. This limits the restoration of ecosystem functions that are essential to re-integrate these artificial micro-deserts within the landscape matrix. 2.We assessed the functional role of local nurse plant species and their traits to restore ecosystem functions related to soil fertility, soil microbial productivity and the reduction of abiotic stress. We sampled...

Data from: Correlated evolution between colouration and ambush site in predators with visual prey lures

Felipe Malheiros Gawryszewski, Miguel A. Calero-Torralbo, Rosemary G. Gillespie, Miguel Rodriguez-Girones & Marie E. Herberstein
The evolution of a visual signal will be affected by signaller and receiver behaviour, and by the physical properties of the environment where the signal is displayed. Crab spiders are typical sit-and-wait predators found in diverse ambush sites, such as tree bark, foliage and flowers. Some of the flower-dweller species present a UV+-white visual lure that makes them conspicuous and attractive to their prey. We hypothesised that UV+-white colouration was associated with the evolution of...

Data from: Intraspecific genetic structure, divergence and high rates of clonality in an amphi-Atlantic starfish

Alex Garcia-Cisneros, Crue Palacín, Carlos Renato R. Ventura, Barbara Feital, Paulo C. Paiva & Rocio Perez Portela
Intraspecific genetic diversity and divergence have a large influence on the adaption and evolutionary potential of species. The widely distributed starfish, Coscinasterias tenuispina, combines sexual reproduction with asexual reproduction via fission. Here we analyse the phylogeography of this starfish to reveal historical and contemporary processes driving its intraspecific genetic divergence. We further consider whether asexual reproduction is the most important method of propagation throughout the distribution range of this species. Our study included 326 individuals...

Data from: Persisting in defaunated landscapes: reduced plant population connectivity after seed dispersal collapse

Néstor Pérez-Méndez, Pedro Jordano & Alfredo Valido
1. Defaunation of large-bodied frugivores could be causing severe losses of crucial ecosystem functions such as seed dispersal. The immediate ecological consequences may include alteration or even collapse of seed-mediated gene flow affecting plant population connectivity, with impacts on the regional scale distribution of genetic variation. Yet these far-reaching consequences of defaunation remain understudied. 2. Here we tested whether human-induced defaunation of the Canarian frugivorous lizards (Gallotia, Lacertidae) altered within-island population connectivity and the amount...

Data from: Prioritizing sites for ecological restoration based on ecosystem services

Francisco A. Comín, Beatriz Miranda, Ricardo Sorando, María R. Felipe-Lucia, Juan J. Jiménez & Enrique Navarro
1. Restoration ecology is moving towards designing restoration actions to maximize ecosystem services (ES). Such restoration actions require planning at large spatial scales, as these are often more meaningful for ecosystem functioning and ES supply. As economic resources to undertake ecological restoration at large scales are scarce, prioritizing sites to enhance multiple ES supply is critical. 2. Our study presents an index, the Relative Aggregated Value of ES (RAVES), to prioritize sites for ecological restoration...

Data from: Resolving recent plant radiations: power and robustness of genotyping-by-sequencing

Mario Fernández-Mazuecos, Greg Mellers, Beatriz Vigalondo, Llorenç Sáez, Pablo Vargas & Beverley J. Glover
Disentangling species boundaries and phylogenetic relationships within recent evolutionary radiations is a challenge due to the poor morphological differentiation and low genetic divergence between species, frequently accompanied by phenotypic convergence, inter-specific gene flow and incomplete lineage sorting. Here we employed a genotyping-by-sequencing (GBS) approach, in combination with morphometric analyses, to investigate a small western Mediterranean clade in the flowering plant genus Linaria that radiated in the Quaternary. After confirming the morphological and genetic distinctness of...

Data from: Poor plant performance under simulated climate change is linked to mycorrhizal responses in a semiarid shrubland

Lupe León-Sánchez, Emilio Nicolás, Marta Goberna, Iván Prieto, Fernando T. Maestre & José Ignacio Querejeta
1.Warmer and drier conditions associated with ongoing climate change will increase abiotic stress for plants and mycorrhizal fungi in drylands worldwide, thereby potentially reducing vegetation cover and productivity and increasing the risk of land degradation and desertification. Rhizosphere microbial interactions and feedbacks are critical processes that could either mitigate or aggravate the vulnerability of dryland vegetation to forecasted climate change. 2.We conducted a four-year manipulative study in a semiarid shrubland in the Iberian Peninsula to...

Data from: Great spotted cuckoo nestlings have no antipredatory effect on magpie or carrion crow host nests in southern Spain

Manuel Soler, Liesbeth De Neve, María Roldán, Tomás Pérez-Contreras & Juan J. Soler
Host defences against cuckoo parasitism and cuckoo trickeries to overcome them are a classic example of antagonistic coevolution. Recently it has been reported that this relationship may turn to be mutualistic in the case of the carrion crow (Corvus corone) and its brood parasite, the great spotted cuckoo (Clamator glandarius), given that experimentally and naturally parasitized nests were depredated at a lower rate than non-parasitized nests. This result was interpreted as a consequence of the...

Data from: Size, age, and habitat determine effectiveness of Palau's Marine Protected Areas

Alan M. Friedlander, Yimnang Golbuu, Enric Ballesteros, Jennifer E. Caselle, Marine Gouezo, Dawnette Olsudong & Enric Sala
Palau has a rich heritage of conservation that has evolved from the traditional moratoria on fishing, or "bul", to more western Marine Protected Areas (MPAs), while still retaining elements of customary management and tenure. In 2003, the Palau Protected Areas Network (PAN) was created to conserve Palau's unique biodiversity and culture, and is the country's mechanism for achieving the goals of the Micronesia Challenge (MC), an initiative to conserve ?30% of near-shore marine resources within...

Data from: Abrupt changes in the composition and function of fungal communities along an environmental gradient in the High Arctic

Grau Oriol, Jozsef Geml, Aaron Pérez-Haase, Josep M. Ninot, Tatiana A. Semenova-Nelsen, Josep Peñuelas & Oriol Grau
Fungi play a key role in soil-plant interactions, nutrient cycling, and carbon flow and are essential for the functioning of arctic terrestrial ecosystems. Some studies have shown that the composition of fungal communities is highly sensitive to variations in environmental conditions, but little is known about how the conditions control the role of fungal communities (i.e. their ecosystem function). We used DNA metabarcoding to compare taxonomic and functional composition of fungal communities along a gradient...

Data from: Generation and maintenance of predation hotspots of a functionally important herbivore in a patchy habitat mosaic

Simone Farina, Aitana Oltra, Jordi Boada, Frederic Bartumeus, Javier Romero & Teresa Alcoverro
1. By modifying how critical ecosystem functions are distributed across the landscape, the spatial configuration and characteristics of patches can play a strong role in structuring communities. In strongly predator-controlled ecosystems, this patchy distribution of function can have complex downstream consequences, subjecting some areas to disproportionately high rates of predation, leaving other areas susceptible to herbivore outbreaks. 2. In this study we assess how spatial attributes at patch and landscape scales potentially influence the spatial...

Data from: The chicken or the egg? Adaptation to desiccation and salinity tolerance in a lineage of water beetles

Susana Pallarés, Paula Arribas, David T. Bilton, Andrés Millán, Josefa Velasco & Ignacio Ribera
Transitions from fresh to saline habitats are restricted to a handful of insect lineages, as the colonization of saline waters requires specialized mechanisms to deal with osmotic stress. Previous studies have suggested that tolerance to salinity and desiccation could be mechanistically and evolutionarily linked, but the temporal sequence of these adaptations is not well established for individual lineages. We combined molecular, physiological and ecological data to explore the evolution of desiccation resistance, hyporegulation ability (i.e.,...

Data from: Climate variability and community stability in Mediterranean shrublands: the role of functional diversity and soil environment

Ignacio M. Pérez-Ramos, Ricardo Díaz-Delgado, Enrique G. De La Riva, Rafael Villar, Francisco Lloret & Teodoro Marañón
1.Understanding how different factors mediate the resistance of communities to climatic variability is a question of considerable ecological interest that remains mostly unresolved. This is particularly remarkable to improve predictions about the impact of climate change on vegetation. 2.Here we used a trait-based approach to analyse the sensitivity to climatic variability over nine years of 19 Mediterranean shrubland communities located in southwest Spain. We evaluated the role of functional diversity and soil environment as drivers...

Data from: The curious case of Bradypus variegatus sloths: populations in threatened habitats are biodiversity components needing protection

Sofia Marques Silva, José A. Dávila, Bryson Voirin, Susana Lopes, Nuno Ferrand & Nadia Moraes-Barros
Studying Neotropical wild populations is of particular interest. While this region is facing an escalating habitat degradation, it also has remarkable biodiversity levels, whose origin we are only beginning to understand. A myriad of processes might have had idiosyncratic effects on its numerous species. Within the hottest Neotropical biodiversity hotspot, the Atlantic Forest (AF), species and genetic diversities are organized latitudinally, with decreasing diversity levels southwards. Bradypus variegatus, the brown-throated three-toed sloth, was one of...

Data from: Neandertal and Denisovan DNA from Pleistocene sediments

Viviane Slon, Charlotte Hopfe, Clemens L. Weiss, Fabrizio Mafessoni, Marco De La Rasilla & Carles Lalueza-Fox
Although a rich record of Pleistocene human-associated archaeological assemblages exists, the scarcity of hominin fossils often impedes the understanding of which hominins occupied a site. Using targeted enrichment of mitochondrial DNA we show that cave sediments represent a rich source of ancient mammalian DNA that often includes traces of hominin DNA, even at sites and in layers where no hominin remains have been discovered. By automation-assisted screening of numerous sediment samples we detect Neandertal DNA...

Data from: A new promising phylogenetic marker to study the diversity of fungal communities: the Glycoside Hydrolase 63 gene

Leticia Pérez-Izquierdo, Emmanuelle Morin, Jean Paul Maurice, Francis Martin, Ana Rincón & Marc Buée
In molecular ecology, the development of efficient molecular markers for fungi remains an important research domain. Nuclear ribosomal internal transcribed spacer (ITS) region was proposed as universal DNA barcode marker for fungi, but this marker was criticized for Indel-induced alignment problems and its potential lack of phylogenetic resolution. Our main aim was to develop a new phylogenetic gene and a putative functional marker, from single-copy gene, to describe fungal diversity. Thus, we developed a series...
