<p style="text-align: justify;"><strong>Aims</strong>: The present paper is focused on wild and feral grapevines from the Ega River gallery forest (Alder grove), one of the most important tributaries of the Ebro River. Since this area was preliminary prospected in 1995, it was our intention to assess the evolution of the ecosystem during this time.</p><p style="text-align: justify;"><strong>Methods and results</strong>: Ampelographic description of wild grapevines shows that all male plants had flowers with fully developed stamens and no gynoecium. No hermaphrodite individuals were detected. No virus infection and symptoms caused by Phylloxera on roots were detected. The Erineum strain of <em>Colomerus vitis</em> constitutes the main phytophagous arthropod. Damages caused by powdery and downy mildew were not lethal for the vines. Around 73% of the wild grapevine individuals found in 1995 had disappeared due to human impacts. The number of rootstocks and producer hybrids (French hybrids) had increased in this period by about 30%. Microvinification of wild berries yielded a wine with very high color intensity and total polyphenol index with a low pH.</p><p style="text-align: justify;"><strong>Conclusion</strong>: The wild grapevine population described has suffered a dramatic regression in the 20-year period between prospections, together with a significant increase of feral accessions thus endangering the endurance of the ecosystem and remaining wild grapevine.</p><p style="text-align: justify;"><strong>Significance and impact of the study </strong>: Wild grapevines are a valuable genetic resource for the genetic improvement of cultivated vines. However, our study shows that human impacts and increasing pressure of feral accessions are threatening wild grapevine populations.</p>

For decades, human activities have gradually destroyed the natural habitats of wild grapevine, Vitis vinifera L. subsp. sylvestris (Gmelin) Hegi, and nowadays this species is endangered in southern Europe. In this paper, 94 populations of this species have been localized and characterized in the Andalusian region in the Iberian Peninsula between 1989 and 2013. Location, ecological aspects, and sanitary characteristics are described. Must properties and in vitro tolerance to calcareous conditions were also checked. The paper also contains a global description of female and male individuals. Two hundred individuals from six river basin populations have been sampled, and their genetic structure analyzed by using 25 nuclear microsatellites loci to investigate the gene diversity of wild grape populations in Andalusia at two levels: total individuals and at river basin populations. Also, the genetic relationship of wild and cultivated accessions has been tested. Wild grapevine is considered the ancestor of the cultivated varieties and should be preserved as this material could be used to start breeding programs of cultivated varieties and also to restore riverbank forests, which constitute one of the worst preserved ecosystems in the area.

The surface roughness of agricultural soils is mainly related to the type of tillage performed, typically consisting of oriented and random components. Traditionally, soil surface roughness (SSR) characterization has been difficult due to its high spatial variability and the sensitivity of roughness parameters to the characteristics of the instruments, including its measurement scale. Recent advances in surveying have greatly improved the spatial resolution, extent, and availability of surface elevation datasets. However, it is still unknown how new roughness measurements relates with the conventional roughness measurements such as 2D profiles acquired by laser profilometers. The objective of this study was to evaluate the suitability of Terrestrial Laser Scanner (TLS) and Structure from Motion (SfM) photogrammetry techniques for quantifying SSR over different agricultural soils. With this aim, an experiment was carried out in three plots (5 × 5 m) representing different roughness conditions, where TLS and SfM photogrammetry measurements were co‐registered with 2D profiles obtained using a laser profilometer. Differences between new and conventional roughness measurement techniques were evaluated visually and quantitatively using regression analysis and comparing the values of six different roughness parameters. TLS and SfM photogrammetry measurements were further compared by evaluating multi‐directional roughness parameters and analyzing corresponding Digital Elevation Models. The results obtained demonstrate the ability of both TLS and SfM photogrammetry techniques to measure 3D SSR over agricultural soils. However, profiles obtained with both techniques (especially SfM photogrammetry) showed a loss of high‐frequency elevation information that affected the values of some parameters (e.g. initial slope of the autocorrelation function, peak frequency and tortuosity). Nevertheless, both TLS and SfM photogrammetry provide a massive amount of 3D information that enables a detailed analysis of surface roughness, which is relevant for multiple applications, such as those focused in hydrological and soil erosion processes and microwave scattering. © 2019 John Wiley & Sons, Ltd.

The purpose of this study was to establish the mean timing of permanent tooth emergence in a low to middle socioeconomic level schoolchildren population sample from the Southeastern part of the Dominican Republic. A total of 900 children (15.6% of the 5-14-year-old schoolchildren from this city) were studied. Girls were relatively advanced in their emergence times except for the canine and second premolar in the maxilla and the first premolar in the mandible. The mean emergence times were, in general, relatively advanced when compared with those of United States whites and blacks, Danish, Canadian Eskimos, French-Canadians, Greenland Eskimos, Icelandics, Southern Chinese and South Africans.

<p style="text-align: justify;"><strong>Aims</strong>: The aim of this paper was to locate and describe the wild grapevine as a phytogenetic resource in Western Pyrenees, including Navarre, Aragon (Spain) and the department of Pyrénées atlantiques (France).</p><p style="text-align: justify;"><strong>Methods and results</strong>: An ampelographic description of wild grapevine populations was made as well as a study of their oenological potential and an evaluation of their sanitary condition. The ampelographic results confirmed the dioecious nature of all the specimens. The microvinification results of two wine samples showed low alcohol content, high acidity (low pH) and high intensity of colour. The sanitary study revealed that the main parasites of the vines were eriophyids (mites), powdery and downy mildews (fungus), with aerial organs being most susceptible (leaves, bunches). No symptoms of phylloxera, nematodes or root destroying fungi were detected. The paper is complemented by a list of the main accompanying botanical species.</p><p style="text-align: justify;"><strong>Conclusion</strong>: This phytogenetic resource is well represented in the area of study, exhibiting a good sanitary status.</p><p style="text-align: justify;"><strong>Significance and impact of the study</strong>: This paper could provide the basis for future genetic studies addressing the possible links between the wild grapevines and the cultivated varieties of the region. Wild grapevines could also be used in future breeding programs.</p>
