Knee function through finite element analysis and the role of Miocene hominoids in our understanding of the origin of antipronograde behaviours: the Pierolapithecus catalaunicus patella as a case studyMarta Pina, Daniel DeMiguel, Francesc Puigvert, Jordi Marcé‐Nogué & Salvador Moyà‐Solà
Although extensive research has been carried out in recent years on human bipedalism origin and evolution, a full understanding of this question is far to be achieved. In this regard, the role of Miocene hominoids emerges as key to better comprehend the locomotor types observed in living apes and humans. Pierolapithecus catalaunicus, an extinct stem great ape from the middle Miocene (c. 12.0 Ma) of the Vallès-Penedès Basin (NE Iberian Peninsula), is the first undoubted...
Estimation of the relative abundance of species in artificial mixtures of insects using low-coverage shotgun metagenomicsLidia Garrido-Sanz, Miquel Àngel Senar & Josep Piñol
Amplicon metabarcoding is an established technique to analyse the taxonomic composition of communities of organisms using high-throughput DNA sequencing, but there are doubts about its ability to quantify the relative proportions of the species, as opposed to the species list. Here, we bypass the enrichment step and avoid the PCR-bias, by directly sequencing the extracted DNA using shotgun metagenomics. This approach is common practice in prokaryotes, but not in eukaryotes, because of the low number...
Influence of socio-economic, demographic and climate factors on the regional distribution of dengue in the United States and MexicoMatthew Watts
Climate change, urbanization, and global trade have contributed to the recent spread of dengue viruses. In this study, we investigate the relationship between dengue occurrence in humans, climate factors (temperature and minimum quarterly rainfall), socio-economic factors (such as household income, regional rates of education, regional unemployment, housing overcrowding, life expectancy, and medical resources), and demographic factors (such as migration flows, age structure of the population, and population density). From a geographical perspective, this study focuses...
Two new diploid species, Aira minoricensis and Aira hercynica are described and illustrated, along with chromosome counts, risk assessment, distribution and habitat, phenology, and comparisons with morphologically similar species. A comparative table and a key for the species of Aira for the Iberian Peninsula and the Balearic Islands are provided to assist in the identification of these overlooked species, and their relationships to other taxa are discussed.
Data from: Partitioning between atmospheric deposition and canopy microbial nitrification into throughfall nitrate fluxes in a Mediterranean forestRossella Guerrieri, Lucas Lecha, Stefania Mattana, Joan Cáliz, Emilio Casamayor, Anna Barceló, Greg Michalski, Josep Penuelas, Anna Àvila & Maurizio Mencuccini
1. Microbial activity plays a central role in nitrogen (N) cycling, with effects on forest productivity. Though N bio-transformations, such as nitrification, are known to occur in the soil, here we investigate whether nitrifiers are present in tree canopies and actively process atmospheric N. 2. This study was conducted in a Mediterranean holm oak (Quercus ilex L.) forest in Spain during the transition from hot dry summer to cool wet winter. We quantified NH4+—N and...
Data from: The role of morbidly obesity in the promotion of metabolic disruptions and non-alcoholic steatohepatitis by Helicobacter PyloriAlbert Lecube, Silvia Valladares, Carolina Lopez-Cano, Liliana Gutiérrez, Andreea Ciudin, José Manuel Fort, Josep Maria Reñé, Xavier Matias-Guiu, Ines De Torres, Marta Bueno, Judit Pallarés & Juan Antonio Baena
Helicobacter pylori (HP) infection has been associated to an increased rate of type 2 diabetes (T2D) and liver disease through its effect on insulin resistance and systemic inflammation. However, results are inconstant and no studies exist in morbidly obese patients, in which both insulin resistance and inflammation coexist. Material and Methods: Cross-sectional study to evaluate the relationship between HP infection and alterations in carbohydrate metabolism, lipid profile, inflammation markers, and liver disease in patients awaiting...
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 dynamicsJofre 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...
Historical species records offer an excellent opportunity to test the predictive ability of range forecasts under climate change, but researchers often consider that historical records are scarce and unreliable, besides the datasets collected by renowned naturalists. Here, we demonstrate the relevance of biodiversity records developed through citizen-science initiatives generated outside the natural sciences academia. We used a Spanish geographical dictionary from the mid-nineteenth century to compile over 10 000 freshwater fish records, including almost 4...
Data from: Wide variation in spatial genetic structure between natural populations of the European beech (Fagus sylvatica) and its implications for SGS comparabilityAlistair S. Jump, Laura Rico, Marta Coll & Josep Peñuelas
Identification and quantification of spatial genetic structure (SGS) within populations remains a central element of understanding population structure at the local scale. Understanding such structure can inform on aspects of the species' biology, such as establishment patterns and gene dispersal distance, in addition to sampling design for genetic resource management and conservation. However, recent work has identified that variation in factors such as sampling methodology, population characteristics, and marker system can all lead to significant...
Angelo Monforte’s Letter to Peter of Aragon and the Early Dissemination of Decembrio’s Translation of Curtius RufusMontserrat Ferrer
This note establishes that in 1438 Angelo Monforte, count of Campobasso, sent to Prince Peter of Aragon a copy of Pier Candido Decembrio’s Italian version of Curtius Rufus, thus documenting the transmission of Decembrio’s work from Milan to Naples. This copy could have been the source of Alfonso de Liñán’s translation into Spanish of Decembrio’s translation.
This note studies and edits a hitherto unknown preface (Barcelona, Biblioteca de Catalunya, MS 1031, fol. 9r-10r) that friar Pere Riu (O. Carm.) addressed to his “lord the Duke,” in all likelihood Crown Prince John of Aragon, possibly in the 1370s. The theological contents of this preface to Riu’s short commentary on Psalm 50 may shed new light on the education of John of Aragon.
