M. C ram4 Abstract: We describe and illustrate anew needle nematode, Longidorus americanum n. sp., associated with patches of severely stunted and chlorotic loblolly pine, ( Pinus taeda L.) seedlings in seedbeds at the Flint River Nursery (Byromville, GA). It is characterized by having females with abody length of 5.4–9.0 mm; lip region slightly swollen, anteriorly flattened, giving the anterior end atruncate appearance; long odontostyle (124–165 µm); vulva at 44%–52% of body length; and tail conoid, bluntly rounded to almost hemispherical. Males are rare but present, and in general shorter than females. The new species is morphologically similar to L. biformis, L. paravineacola, L. saginus, and L. tarjani but differs from these species either by the body, odontostyle and total stylet length, or by head and tail shape. Sequence data from the D2–D3 region of the 28S rDNA distinguishes this new species from other Longidorus species. Phylogenetic relationships of Longidorus americanum n. sp. with other longidorids based on analysis of this DNA fragment are presented. Additional information regarding the distribution of this species within the region is required.

The genera isolated were Corynebacterium sp., Lactobacillus sp. and Staphylococcus sp. Result showed a significant difference (p≤0.05) in the efficacy of F. hygrometrica extract and the antibiotics on the test organisms. The zones of inhibition in diameter of the test organisms ranged between 12.50±2.08mm (F. hygrometrica extract) and 33.50±0.71mm (Cefotaxamine); 11.75±2.3608mm (F. hygrometrica extract) and 25.50±0.71mm (Cefotaxamine) and 0.00±0.00mm (Tetracycline) and 29.50±0.71mm (Cefotaxamine) for Lactobacillus sp, Staphylococcus sp. and Corynebacterium sp. respectively while the control showed no zone of inhibition (0.00±0.00mm). The test organisms were sensitive to the antibiotics except Corynebacterium being resistant to Tetracycline. The minimal inhibitory concentration of plant extract and antibiotics showed a significant difference (p≤0.05) on the test organisms and ranged between 0.65±0.21 mg/ml (Cefotaxamine) and 4.25±0.35 mg/ml (Penicillin G); 0.04±0.01 mg/ml (Penicillin G) and 2.50±0.00 mg/ml ((F.

  • Strikes and Rural Unrest During the Second Spanish Republic (1931–1936): a Geographic Approach
    sustainability Article Strikes and Rural Unrest during the Second Spanish Republic (1931–1936): A Geographic Approach Javier Puche 1,* and Carmen González Martínez 2 1 Faculty of Social and Human Sciences, University of Zaragoza, Ciudad Escolar s/n, 44003 Teruel, Spain 2 Faculty of Letters, University of Murcia, Campus de la Merced, 30071 Murcia, Spain; [email protected] * Correspondence: [email protected]; Tel.: +34-978-645-337 Received: 27 October 2018; Accepted: 17 December 2018; Published: 21 December 2018 Abstract: This article analyses the evolution and geographic distribution of the rural unrest that prevailed during the years of the Second Spanish Republic (1931–1936), a period characterised by political instability and social conflict. The number of provincial strikes recorded in the forestry and agricultural industries and complied by the Ministry of Labour and Social Welfare constitute the primary source of the study. Based on this information, maps of the regional and provincial distribution of the agricultural unrest have been created for the republican period. The results reveal that, contrary to the traditional belief which confines the rural unrest of this period to the geographic areas of the latifundios (large estates), Spanish agriculture, in all its diversity, was hit by collective disputes. Although the areas of the latifundios were most affected by the agricultural reform of 1932, the data show that the extension of the unrest in the Spanish countryside was also the result of the refusal of the landowners to accept and apply the new republican collective bargaining agreement. The number of strikes increased during the period 1931–1933, fell between 1934 and 1935, and increased again during the months of the Popular Front (February to July 1936).

  • Mapping Urban Water Governance Models in the Spanish Mediterranean Coastline
    Water and Society IV 75 MAPPING URBAN WATER GOVERNANCE MODELS IN THE SPANISH MEDITERRANEAN COASTLINE RUBÉN VILLAR & ANA ARAHUETES Instituto Interuniversitario de Geografía, Universidad de Alicante, Spain ABSTRACT The heterogeneity of governance and management models of municipal water supply in the Spanish Mediterranean coastline has increased in recent decades. This diversity is explained by the increase of private companies responsible for the management of the local water service and the presence of supramunicipal public entities responsible for water catchment, treatment and distribution to the municipalities. Based on the review of the existing literature, the information available on the websites of the leading corporate groups in the water sector and contacting with councils, the companies and supramunicipal entities involved in the service of municipal water in the Mediterranean coastline have been identified. The objective of this work is to analyse the territorial presence of the main actors in the urban water management through its cartographic representation, as well as analyse its ownership and importance in terms of population supplied. This analysis shows a high presence of companies belonging to the AGBAR group that supply around half of the total population in the Spanish coastline municipalities. Likewise, there is a regional specialization of certain private companies that concentrate the urban water management for the most part of the coastline municipalities. This is the case of FACSA, which manages the water services in 87% of coastline municipalities in Castellón, or Hidraqua in Alicante, that operates in the 65%. Furthermore, the presence of large supramunicipal public entities is widespread along the coastline, especially in Catalonia and the southeast.

However, the high re-discovery rate of antinematode compounds from terrestrial environments necessitates a new repository for future drug research. Marine epiphytic bacteria are hypothesised to produce nematicidal compounds as a defence against bacterivorous predators, thus representing a promising, yet underexplored source for antinematode drug discovery. The marine epiphytic bacterium Pseudoalteromonas tunicata is known to produce a number of bioactive compounds. Screening genomic libraries of P. tunicata against the nematode Caenorhabditis elegans identified a clone (HG8) showing fast-killing activity. However, the molecular, chemical and biological properties of HG8 remain undetermined. A novel Nematode killing protein-1 (Nkp-1) encoded by an uncharacterised gene of HG8 annotated as hp1 was successfully discovered through this project. The Nkp-1 toxicity appears to be nematode-specific, with the protein being highly toxic to nematode larvae but having no impact on nematode eggs.

    Nematology, 2011, Vol. 13(3), 295-306 Molecular and morphological characterisation of species within the Xiphinema americanum-group (Dorylaimida: Longidoridae) from the central valley of Chile ∗ Pablo MEZA 1,2, ,ErwinABALLAY 1 and Patricio HINRICHSEN 2 1 Faculty of Agronomy, Universidad de Chile, Avenida Santa Rosa 11315, Santiago, Chile 2 Biotechnology Laboratory, INIA La Platina, Avenida Santa Rosa 11610, Santiago, Chile Received: 7 January 2010; revised: 21 June 2010 Accepted for publication: 21 June 2010 Summary – Species of the Xiphinema americanum-group are among the most damaging nematodes for a diverse range of crops. This group includes 51 nominal species throughout the world. They are very difficult to identify by traditional taxonomic methods. Despite its importance in agriculture, the species composition of this group in many countries, including Chile, remains unknown. In order to identify the species in the central valley of Chile, we studied the morphological, morphometric and molecular diversity of 13 populations. Through classical taxonomic methods two species, X. inaequale and X. peruvianum, were identified with clear differences in the shape of the lip region. The DNA sequences of the ITS of ribosomal genes revealed divergences in the nucleotide sequences of the two species from 7.3% in ITS1 to 14.7% in ITS2. These results confirmed the presence of two distinct species, namely X. peruvianum and X. inaequale, in the northern and southern parts of the central valley of Chile, respectively. PCR-RFLP was developed for rapid species identification of these two species. Keywords – molecular, morphology, morphometrics, taxonomy, Xiphinema californicum, Xiphinema inaequale, Xiphinema peruvia- num. The Xiphinema americanum-group comprises 51 nom- nologies has opened a new spectrum of possibilities in ne- inal species found all over the world (Lamberti et al., matode taxonomy.

ZooKeys 574: 43–55. doi: 10.3897/zookeys.574.7222 Abstract The dataset of free-living marine nematodes of San Antonio Bay is based on sediment samples collected in February 2009 during doctoral theses funded by CONICET grants. A total of 36 samples has been taken at three locations in the San Antonio Bay, Santa Cruz Province, Argentina on the coastal littoral at three tidal levels. This presents a unique and important collection for benthic biodiversity assessment of Patagonian nematodes as this area remains one of the least known regions.

  • Dorylaimida: Nordiidae) from California, with the First Molecular Study and an Updated Taxonomy of the Genus
    animals Article Morphological and Molecular Characterization of Kochinema farodai Baqri and Bohra, 2001 (Dorylaimida: Nordiidae) from California, with the First Molecular Study and an Updated Taxonomy of the Genus Sergio Álvarez-Ortega Departamento de Biología y Geología, Física y Química Inorgánica, Universidad Rey Juan Carlos, Campus de Móstoles, 28933 Madrid, Spain; [email protected] Received: 16 November 2020; Accepted: 30 November 2020; Published: 4 December 2020 Simple Summary: In this paper, a population of a free-living nematode collected from Northern California (USA) is identified and studied. The aim of the present work is to characterize a Californian population of the nematode genus Kochinema, with morphological and molecular methods. In addition, a revision of this genus is also provided including an updated diagnosis, a list of species, a key to species identification, and a compendium of their main morphometrics and distribution data. Abstract: This paper deals with the morphological and molecular characterization of Kochinema farodai Baqri and Bohra, 2001, with an integrative approach. The finding of K. faroidai in California is a remarkable biogeographical novelty, as it is the first American record of the species. Molecular data herein obtained represent the first molecular study of the genus Kochinema. Furthermore, scanning electron microscopy (SEM) observations of a member of Kochinema are provided for the first time. Additionally, this contribution provides new insights into the phylogeny and taxonomy of the nematode genus Kochinema. A brief historical outline of the matter is presented. Then, the morphological pattern of the genus is revised and illustrated, the anterior position of amphids, whose opening is located on lateral lip, being its most relevant diagnostic feature.
