Neus Martinez-Abadias, Roger Mateu Estivill, Jaume Sastre Tomas, Susan Motch Perrine, Melissa Yoon, Alex Robert-Moreno, Jim Swoger, Lucia Russo, Kazuhiko Kawasaki, Joan Richtsmeier, James Sharpe & Alexandre Robert-Moreno
The earliest developmental origins of dysmorphologies are poorly understood in many congenital diseases. They often remain elusive because the first signs of genetic misregulation may initiate as subtle changes in gene expression, which are hard to detect and can be obscured later in development by secondary effects. Here, we develop a method to trace the origins of phenotypic abnormalities by accurately quantifying the 3D spatial distribution of gene expression domains in developing organs. By applying...

Data from: Latitudinal variation in seagrass herbivory: global patterns and explanatory mechanisms

Adriana Vergés, Christopher Doropoulos, Rob Czarnik, Kathryn McMahon, Nil Llonch & Alistair G. B. Poore
Aim: The aim was to quantify latitudinal patterns in seagrass–herbivore interactions in the context of a warming climate. Location: We carried out a global meta‐analysis combined with a field experiment across 1,700 km and 12° of latitude in Western Australia. Time period: 1984–2014. Major taxa studied: Seagrasses. Methods: We first synthesized the global literature on herbivore exclusion experiments in seagrasses to test whether differences in herbivore impacts are related to latitude and sea surface temperature....

Data from: Marine protected areas enhance structural complexity but do not buffer the consequences of ocean warming for an overexploited precious coral

Ignasi Montero-Serra, Joaquim Garrabou, Daniel F. Doak, Jean-Baptiste Ledoux & Cristina Linares
1. Global warming and overexploitation both threaten the integrity and resilience of marine ecosystems. Many calls have been made to at least partially offset climate change impacts through local conservation management. However, a mechanistic understanding of the interactions of multiple stressors is generally lacking for habitat-forming species; preventing the development of sound conservation strategies. 2. We examined the effectiveness of no-take marine protected areas (MPAs) at enhancing structural complexity and resilience to climate change on...

Data from: Drivers of spatio-temporal patterns of salinity in Spanish rivers: a nationwide assessment

Edurne Estévez, Tamara Rodríguez-Castillo, Alexia M Aria González-Ferreras, Miguel Cañedo-Argüelles & José Barquín
The salinization of freshwaters is a global water quality problem that leads to the biological degradation of aquatic ecosystems. However, little is known about the spatial extent of freshwater salinization and the relative contribution of each human activity (e.g. agriculture, urbanization, mining or shale-gas extraction). Here, we investigated environmental factors that explain spatio-temporal patterns of water salinity and examined the causes, the extent and the degree of salinization of Spanish rivers. Results showed a strong...

Data from: How do baleen whales stow their filter? A comparative biomechanical analysis of baleen bending

Alexander J. Werth, Diego Rita, Michael V. Rosario, Michael J. Moore & Todd L. Sformo
Bowhead and right whale (balaenid) baleen filtering plates, longer in vertical dimension (3-4+ m) than the closed mouth, presumably bend during gape closure. This has not been observed in live whales, even with scrutiny of videorecorded feeding sequences. To determine what happens to baleen as gape closes, we conducted an integrative, multifactorial study including materials testing, functional (flow tank and kinematic) testing, and histological examination. We measured baleen bending properties along the dorsoventral length of...

Data from: Phylogeography of western Mediterranean Cymbalaria (Plantaginaceae) reveals two independent long-distance dispersals and entails new taxonomic circumscriptions

Pau Carnicero, Peter Schönswetter, Pere Fraga Arguimbau, Núria Garcia-Jacas, Llorenç Sáez & Mercè Galbany-Casals
The Balearic Islands, Corsica and Sardinia (BCS) constitute biodiversity hotspots in the western Mediterranean Basin. Oligocene connections and long distance dispersal events have been suggested to cause presence of BCS shared endemic species. One of them is Cymbalaria aequitriloba, which, together with three additional species, constitute a polyploid clade endemic to BCS. Combining amplified fragment length polymorphism (AFLP) fingerprinting, plastid DNA sequences and morphometrics, we inferred the phylogeography of the group and evaluated the species’...

Data from: Herbivore control in connected seascapes: habitat determines when population regulation occurs in the life history of a key herbivore

Jordi Boada, Simone Farina, Rohan Arthur, Javier Romero, Patricia Prado & Teresa Alcoverro
Herbivore outbreaks often trigger catastrophic overgrazing events in marine macrophyte ecosystems. The sea urchin Paracentrotus lividus, the dominant herbivore of shallow Mediterranean seascapes, is capable of precipitating shifts to barrens when its populations explode. P. lividus is found ubiquitously in rocky macroalgal communities and in sandy seagrass meadows of Posidonia oceanica, two of the most important subtidal habitats in the Mediterranean. We explored if habitat-specific regulation across the principal stages of the urchin life cycle...

Data from: Intrinsically regulated learning is modulated by synaptic dopamine signaling

Pablo Ripollés, Laura Ferreri, Ernest Mas-Herrero, Helena Alicart, Alba Gómez-Andrés, Josep Marco-Pallares, Rosa Maria Antonijoan, Toemme Noesselt, Marta Valle, Jordi Riba & Antoni Rodriguez-Fornells
We recently provided evidence that an intrinsic reward-related signal-triggered by successful learning in absence of any external feedback-modulated the entrance of new information into long-term memory via the activation of the dopaminergic midbrain, hippocampus, and ventral striatum (the SN/VTA-Hippocampal loop; Ripollés et al., 2016). Here, we used a double-blind, within-subject randomized pharmacological intervention to test whether this learning process is indeed dopamine-dependent. A group of healthy individuals completed three behavioral sessions of a language-learning task...

Data from: Warming impacts on early life stages increase the vulnerability and delay the population recovery of a long-lived habitat-forming macroalga

Pol Capdevila, Bernat Hereu, Roberto Salguero-Gómez, Graciel·La Rovira, Alba Medrano, Emma Cebrian, Joaquim Garrabou, Diego K. Kersting & Cristina Linares
1. Understanding the combined effects of global and local stressors is crucial for conservation and management, yet challenging due to the different scales at which these stressors operate. Here we examine the effects of one of the most pervasive threats to marine biodiversity, ocean warming, on the early life stages of the habitat-forming macroalga Cystoseira zosteroides, its long-term consequences for population resilience and its combined effect with physical stressors. 2. First, we performed a controlled...

Data from: The grass was greener: repeated evolution of specialized morphologies and habitat shifts in ghost spiders following grassland expansion in South America

Fadia Sara Ceccarelli, Nicolas Mongiardino Koch, Eduardo M. Soto, Mariana L. Barone, Miquel A. Arnedo & Martin J. Ramirez
While grasslands, one of Earth’s major biomes, are known for their close evolutionary ties with ungulate grazers, these habitats are also paramount to the origins and diversification of other animals. Within the primarily South American spider subfamily Amaurobioidinae (Anyphaenidae), several species are found living in the continent’s grasslands, with some displaying putative morphological adaptations to dwelling unnoticed in the grass blades. Here, a dated molecular phylogeny provides the backbone for analyses revealing the ecological and...

Data from: Postglacial range expansion shaped the spatial genetic structure in a marine habitat-forming species: implications for conservation plans in the Eastern Adriatic Sea

Jean-Baptiste Ledoux, Maša Frleta-Valić, Silvija Kipson, Agostinho Antunes, Emma Cebrian, Cristina Linares, Pablo Sánchez, Raphael Leblois & Joaquim Garrabou
Aim: Understanding how historical and contemporary processes shaped and maintain spatial patterns of genetic diversity is a major goal for conservation biologists. Here, we characterized the pattern of neutral genetic diversity and we inferred underlying processes in the habitat-forming octocoral Paramuricea clavata in the Adriatic Sea, a peculiar phylogeographic region of the Mediterranean Sea. Location: Eastern coast of the Adriatic Sea. Methods: We genotyped seven microsatellites in 454 individuals of P. clavata from 13 populations...

Data from: Differentially expressed mRNA targets of differentially expressed miRNAs predict changes in the TP53 axis and carcinogenesis related pathways in human keratinocytes chronically exposed to arsenic

Laila Al-Eryani, Sabine Waigel, Ashish Tyagi, Jana Peremarti, Samantha F. Jenkins, Chendil Damodaran & J. Christopher States
Background: Arsenic is a widely distributed toxic natural element. Chronic arsenic ingestion causes several cancers, especially skin cancer. Arsenic-induced cancer mechanisms are not well defined, but several studies indicate that mutation is not the driving force and that microRNA expression changes play a role. Chronic low arsenite exposure malignantly transforms immortalized human keratinocytes (HaCaT), serving as a model for arsenic-induced skin carcinogenesis. Hypothesis: Early changes in miRNA expression in HaCaT cells chronically exposed to arsenite...

Data from: Phenotypic biomarkers of climatic impacts on declining insect populations: a key role for decadal drought, thermal buffering and amplification effects and host plant dynamics

Jofre Carnicer, Constantí Stefanescu, Maria Vives-Ingla, Carlos López, Sofia Cortizas, Christopher Wheat, Roger Vila, Joan Llusià & Josep Penuelas
1. Widespread population declines have been reported for diverse Mediterranean butterflies over the last three decades, and have been significantly associated to increased global change impacts. The specific landscape and climatic drivers of these declines remain uncertain for most declining species. 2. Here we analyse whether plastic phenotypic traits of a model butterfly species (Pieris napi) perform as reliable biomarkers of vulnerability to extreme temperature impacts in natural populations, showing contrasting trends in thermally exposed...

Data from: Estimation of inhalation flow profile using audio-based methods to assess inhaler medication adherence

Terence E. Taylor, Helena Lacalle Muls, Richard W. Costello & Richard B. Reilly
Asthma and chronic obstructive pulmonary disease (COPD) patients are required to inhale forcefully and deeply to receive medication when using a dry powder inhaler (DPI). There is a clinical need to objectively monitor the inhalation flow profile of DPIs in order to remotely monitor patient inhalation technique. Audio-based methods have been previously employed to accurately estimate flow parameters such as the peak inspiratory flow rate of inhalations, however, these methods required multiple calibration inhalation audio...

Data from: Strong linkages between depth, longevity and demographic stability across marine sessile species

Ignasi Montero-Serra, Cristina Linares, Daniel F. Doak, Jean-Baptiste Ledoux & Joaquim Garrabou
Understanding the role of the environment in shaping the evolution of life histories remains a major challenge in ecology and evolution. We synthesize longevity patterns of marine sessile species and find strong positive relationships between depth and maximum lifespan across multiple sessile marine taxa, including corals, bivalves, sponges and macroalgae. Using long-term demographic data on marine sessile and terrestrial plant species, we show that extreme longevity leads to strongly dampened population dynamics. We also used...

Data from: Biogeographical scenarios modulate seagrass resistance to small-scale perturbations

Fernando Tuya, Yolanda Fernández‐Torquemada, Jesús Zarcero, Yoana Del Pilar-Ruso, Ina Csenteri, Fernando Espino, Pablo Manent, Leticia Curbelo, Adriá Antich, José A. De La Ossa, Laura Royo, Inés Castejon-Silvo, Gabriele Procaccini, Jorge Terrados & Fiona Tomas
1. Seagrasses constitute a key coastal habitat worldwide, but are are exposed to multiple perturbations. Understanding elements affecting seagrass resistance to disturbances is critical for conservation. Distinct biogeographical scenarios are intrinsically linked with varying ecological and evolution backgrounds shaped across millennia. 2. We addressed whether the resistance (change in shoot abundances) and performance (change in leaf morphology and growth) of the seagrass Cymodocea nodosa to a local stressor, light reduction, varied across three regions (Southeast...
