(2020) Environmental factors affect the response of microbial extracellular enzyme activity in soils when determined as a funciton of water availability and temperature. Ecology and Evolution (Artícle in press), RDA plot showing the correspondence of water activity giving the optimum enzyme activity and environmental parameters. Capital letters (in black) represent the sampled soils (G, Galicia, P, Aragón; S, Salamanca; C, Sevilla; T, Cádiz). Arrows represent the environmental variables (soil texture, sand and silt content) contributing significantly to explain the variability of water activity resulting in optimum enzyme activity. The distribution of enzyme activities are presented in red: Glu_20, glucosidase activity at 20ºC; Glu_60, glucosidase activity at 60ºC; Pho_20, phosphatase activity at 20ºC; Pho_60, phosphatase activity at 60ºC; Pro_20, protease activity at 20ºC; Pro_60, protease activity at 60ºC.

Dataset and code of the article., Reliable crop monitoring systems provide critical information to detect and track anomalies in the status of crops. These systems are fundamental for the development of integrated methodologies that inform agricultural policy, market analysis, or producer decision-making. They are also used in the development of early warning systems that permit to anticipate drought conditions and trigger action to mitigate short term food shortages or to stabilize the structure and pricing of agricultural markets. Current efforts to develop crop monitoring systems exploit meteorological and crop growth models, and satellite imagery. However, legacy sources of information such as operational crop rating surveys that have long and uninterrupted records receive less attention. We argue that crop rating data, despite its subjective and non-quantitative nature, captures the complexities of assessing the 'status' of a crop better than any model or remote sensing retrieval. This is because crop rating data naturally represents the broad expert knowledge of many individual surveyors spread throughout the country. Crop rating surveys in effect constitute a sophisticated network of "humans as sensors" that provide consistent and accurate information on crop progress. We analyze data from the USDA Crop Progress and Condition (CPC) survey between 1987 and 2019 for four major crops across the US (corn, soybeans, winter wheat, and upland cotton). We show how the original qualitative data can be transformed into a continuous, probabilistic variable better suited to quantitative analysis, and demonstrate it can be used to monitor crop status and provide early predictions of crop yields., Peer reviewed

Images of dental surfaces obtained from confocal microscope Plu Neos Sensofar, Dental Microwear Analysis (DMA) is currently used for obtaining information on diet of different animal species. Low-magnification Microwear Dental Analysis (LMDA) is a DMA technique based on the identification of microfeatures (pits and scratches) on the tooth enamel surface. During the last decade, Dental Microwear Texture Analysis (DMTA) has gained momentum as an alternative quantitative methodology thus offering more reliable and replicable results and allowing highlighting subtle dietary differences. In this paper we explore the capacities of LMDA and DMTA for discriminating flock managing strategies. Two groups of sheep that were fed differently during the last month of life, one roaming on rangeland, combining Mediterranean forest and meadows and the other on grassland were analysed. While LMDA did not allow discriminating both groups, DMTA showed significant differences between them. DMTA revealed good predictive capacity for the correct classification of the individuals grazing on grasslands, and a poor one for the ones grazing on rangeland, as some of them overlapped with the grassland group. The limitation for correctly classifying roaming individuals is probably explained by the variable composition of plants on rangeland. We used the classificatory rule obtained from the experimental program to classify two archaeological collections of caprines (sheep and goats), from two Iron Age sites from the north-east of the Iberian Peninsula: The Iberian site of El Turó de la Font de la Canya and the Greek colony of Empúries. Finally, we compared the results with those obtained in previous studies using low-magnification microwear techniques (LMDA). In this way, we show the potential of DMTA for discriminating between animal feeding strategies in the past., Peer reviewed

Snapshots of spin structures at selected fields, where the largest deviations from the uniform magnetization state are observed., [EN] We report the results of an unpolarized small-angle neutron-scattering (SANS) study on Mn-Zn ferrite (MZFO) magnetic nanoparticles with the aim to elucidate the interplay between their particle size and the magnetization configuration. We study different samples of single-crystalline MZFO nanoparticles with average diameters ranging between 8 to 80 nm, and demonstrate that the smallest particles are homogeneously magnetized. However, with increasing nanoparticle size, we observe the transition from a uniform to a nonuniform magnetization state. Field-dependent results for the correlation function confirm that the internal spin disorder is suppressed with increasing field strength. The experimental SANS data are supported by the results of micromagnetic simulations, which confirm an increasing inhomogeneity of the magnetization profile of the nanoparticle with increasing size. The results presented demonstrate the unique ability of SANS to detect even very small deviations of the magnetization state from the homogeneous one., UE, programa H2020, Proyecto AMPHIBIAN n º 720853., Dataset description: >>> EXPERIMENTAL DATA folder "XRD data" containes the XRD patterns of all the samples presented in the manuscript folder "Magnetic data" containes the M(H) curves of all the samples presented in the manuscript measured at room temperature in a field range of � 5 T folder "TEM data" containes the TEM images of all the samples presented in the manuscript >>> SIMULATED DATA prb_mzfo_fig10.png Microstructures used in the micromagnetic simulations.
