Data from: Selection on structural allelic variation biases plasticity estimates

Mauro Santos, Margarida Matos, Sheng Pei Wang & David M Althoff
Wang and Althoff (2019) explored the capacity of Drosophila melanogaster to exhibit adaptive plasticity in a novel environment. In a full-sib, half-sib design, they scored the activity of the enzyme alcohol dehydrogenase (ADH) and plastic responses, measured as changes in ADH activity across ethanol concentrations in the range of 0-10% (natural variation) and 16% (the novel environment). ADH activity increased with alcohol concentration, and there was a positive association between larval viability and ADH activity...

Angelo Monforte’s Letter to Peter of Aragon and the Early Dissemination of Decembrio’s Translation of Curtius Rufus

Montserrat 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.

Data from: Two New Species of Aira (Poaceae) from the Iberian Peninsula and the Balearic Islands

Maria Angeles Ortiz Herrera, Llorenç Sáez, Javier López-Alvarado, Pere Fraga, Regina Berjano & Carlos Romero-Zarco
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 forest

Rossella 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...

Influence of socio-economic, demographic and climate factors on the regional distribution of dengue in the United States and Mexico

Matthew 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...

Data from: Evolutionary potential of thermal preference and heat tolerance in Drosophila subobscura

Luis E. Castañeda, Valèria Romero-Soriano, Andres Mesas, Derek A. Roff & Mauro Santos
Evolutionary change of thermal traits (i.e. heat tolerance and behavioral thermoregulation) is one of the most important mechanisms exhibited by organisms to respond to global warming. However, the evolutionary potential of heat tolerance, estimated as narrow-sense heritability, depends on the methodology employed. An alternative adaptive mechanism to buffer extreme temperatures is behavioral thermoregulation, although the association between heat tolerance and thermal preference is not clearly understood. We suspect that methodological effects associated with the duration...

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 study

Marta 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...

Data from: Spatial variability in a plant-pollinator community across a continuous habitat: high heterogeneity in the face of apparent uniformity

Sara Reverté, Jordi Bosch, Xavier Arnan, Tomas Roslin, Constanti Stefanescu, J. A. Calleja, Roberto Molowny-Horas, Carlos Hernández-Castellano & Anselm Rodrigo
Large-scale spatial variability in plant-pollinator communities (e.g., along geographic gradients, across different landscapes) is relatively well understood. However, we know much less about how these communities vary at small scales within a uniform landscape. Plants are sessile and highly sensitive to microhabitat conditions, whereas pollinators are highly mobile and, for the most part, display generalist feeding habits. Therefore, we expect plants to show greater spatial variability than pollinators. We analysed the spatial heterogeneity of a...

Pere Riu’s Preface to His Commentary on the Miserere

Montserrat Domingo & Lluís Cabré
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.
