Morphological and physical chemical characterization of main agricultural plastics articles used for protected cultivation systems during ageing in fields, and collection practices
<p>This dataset includes data generated upon the implementation of the ST 1.2.1 "Analysis of degradation and fragmentation of AP and transfer of MNP to soil". The activities dealt with the study of degradation and fragmentation from weathering and agricultural practices of conventional and biodegradable AP relevant for transfer of MNP to soil (during both use and end of life). In particular, the experimental data refer to characterization of biodegradable mulch films, pristine (coded M-BIO0) or subjected to photo-oxidative weathering (M-BIO192), as well as the same samples buried in soil for varying time periods, up to 353 days. The folders included contain gel permeation chromatography (GPC) and Matrix-assisted Laser Desorption Ionization (MALDI-TOF) data, which account for the change in film molecular weight upon soil burial. Furthermore, Differential Scanning Calorimetry (DSC) data and Scanning Electron Microscopy (SEM) and Water Contact Angle (WCA) images of some selected samples are also provided. The folder named MS RAW FILES.zip includes all the mass spectrometry raw data.</p>
Measurements from CalCOFI cruises in the California Current System, including log of station information, weather, sea conditions as well as physical, chemical and biological measurements including including temperature, salinity, oxygen, density, sigma theta, phosphate, silicate, nitrite, nitrate, ammonia, chlorophyll a, integrated chlorophyll a, primary productivity, and integrated primary production. 1949 - January 2020
Since 1949, hydrographic and biological data of the California Current System have been collected on quarterly CalCOFI cruises. The 59+ year hydrographic time-series includes weather, temperature, salinity, oxygen and phosphate observations. In 1961, nutrient analysis expanded to include silicate, nitrate and nitrite; in 1973, chlorophyll was added; in 1984, C14 primary productivity incubations were added. These data are being provided here in collaboration with CalCOFI-SIO in order to provide an additional queriable interface to the data. The data are updated on a regular basis from the CalCOFI hydrographic database.

Data from: Highlighting potential physical and chemical cues involved in conspecific recognition system in a predator nematode, Seinura caverna
<p class="MsoNormal"><span>Conspecific recognition is the ability to distinguish and respond to individuals of the same species. In nematodes, this behavior can mediate aggregation, feeding behavior, or mating. Here, we investigated whether and how the predatory nematode <em>Seinura caverna</em> recognizes and avoids conspecifics to prey on. In predation assays, <em>S. caverna</em> did not kill conspecifics, but killed nematodes of three heterospecific species. Interestingly, <em>S. caverna</em> did not kill <em>Ektaphelenchoides</em> <em>spondylis</em> nematodes. <em>S. caverna</em> did not eject its stylet when encountering conspecifics or <em>E. spondylis</em>. The characterization of the internal cuticle structure of 13 nematode species suggested that the cuticle may play a role in the preying decision, as <em>E. spondylis</em> and <em>S. caverna</em> exhibited similar, type III, cuticle layers. Chemical extracts from <em>S.</em> <em>caverna</em> further repelled conspecifics. We discuss the potential hierarchical use of physical and chemical cues in <em>S. caverna</em> predation behavior and provide insights into the evolutionary adaptations and behavior of this organism. </span></p>
