Linguistic laws in speech: the case of Catalan and Spanish

Ivan González Torre, Antoni Hernández-Fernández, Juan-María Garrido & Lucas Lacasa
In this work we explore in an oral corpus of Catalan and Spanish (Glissando Corpus) four classical linguistic laws (Zipf's law, Herdan's law, Brevity law, and Menzerath-Altmann's law) in oral communication, both in physical units and in symbolic units measured in speech transcriptions, and we also reviewed two more laws recently reformulated: lognormality law and size-rank law. Our results reinforce with empirical evidence in two more languages the 'physical hypothesis' according to which linguistic laws...

Importance of spatio-temporal connectivity to maintain species experiencing range shifts

Jun-Long Huang, Marco Andrello, Alexandre Martensen, Santiago Saura, Dian-Feng Liu, Jian-Hua He & Marie-Josée Fortin
Climate change can affect the habitat resources available to species by changing habitat quantity, suitability and spatial configuration, which largely determine population persistence in the landscape. In this context, dispersal is a central process for species to track their niche. Assessments of the amount of reachable habitat (ARH) using static snap-shots do not account, however, for the temporal overlap of habitat patches that may enhance stepping-stone effects. Here, we quantified the impacts of climate change...

Data from: Early plant development depends on embryo damage location: the role of seed size in partial seed predation

Ramón Perea García-Calvo, Geraldo Fernandes & Rodolfo Dirzo
Data on 1) Observed weevil-infested acorns in the field; 2) Germination rates and times, and seedling emergence of control and embryo-damaged acorns; 3) Seedling performance and physiology of seedlings

Surface indicators are correlated with soil multifunctionality in global drylands

David Eldridge, Manuel Delgado-Baquerizo, José Luis Quero, Victoria Ochoa, Beatriz Gonzalo, Pablo García-Palacios, Cristina Escolar, Miguel Garcia-Gomez, Laura Beinticinco, Matthew Bowker, Donaldo Bran, Ignacio Castro, Alex Cea, Mchich Derak, Carlos Ivan Espinosa, Adriana Fronertino, Juan Gaitán, Gabriel Gatica, Susana Gómez-González, Wahida Ghiloufi, Julio Gutierrez, Elizabeth Gusmán-M., Rosa Hernandez, Frederic Hughes, Walter Muiño … & Fernando Maestre
1. Multiple ecosystem functions need to be considered simultaneously to manage and protect the many ecosystem services that are essential to people and their environments. Despite this, cost effective, tangible, relatively simple, and globally-relevant methodologies to monitor in situ soil multifunctionality, i.e. the provision of multiple ecosystem functions by soils, have not been tested at the global scale. 2. We combined correlation analysis and structural equation modelling to explore whether we could find easily measured,...

Xenon hydrate as an analogue of methane hydrate in geologic systems out of thermodynamic equilibrium

Xiaojing Fu, William Waite, Luis Cueto-Felgueroso & Ruben Juanes
This data set contains simulation results of hydrate growth on a gas-liquid interface for both methane and xenon hydrate systems. The simulations are performed on a 1D domain of 115 micron in length and for a duration of 40 minutes. The data set contains two MATLAB data files (methane_data.mat and xenon_data.mat) and one file to help users to visualize the data (plot_data.m). In the file plot_data.m, we also use experimental data from Taylor et al....

Building deformation caused by tunnelling: centrifuge modelling

Stefan Ritter, Giorgia Giardina, Andrea Franza & Matthew DeJong
This paper investigates the deformation of buildings due to tunnelling-induced soil displacements. Centrifuge model tests of 3D printed building models subject to a plane-strain tunnel excavation in dense, dry sand are discussed. The small-scale structures replicate important building characteristics including brittle material properties similar to masonry, a realistic building layout, façade openings, strip footings and a rough soil-structure interface. Digital images were captured during the experiments, enabling image-based measurements of the building response. Results demonstrate...

Hydropeaking affects germination and establishment of riverbank vegetation

María D. Bejarano, Álvaro Sordo-Ward, Carlos Alonso, Roland Jansson & Christer Nilsson
Hydropeaking, defined as frequent and rapid variation in flow in regulated rivers with hydropower plants over a short period of time, usually sub-daily to weekly, alters hydraulic parameters such as water levels or flow velocity and exerts strong impacts on fluvial ecosystems. We evaluated the effects of hydropeaking on riverbank vegetation, specifically assessing the germination and establishment of seedlings and cuttings of plant species representing a variation in traits. We used seeds and seedlings and...
