    The taxonomic status of Aphelenchoides besseyi Christie, 1942 (Nematoda: Aphelenchoididae) populations from the southeastern USA, and description of Aphelenchoides pseudobesseyi sp. n.
    (Brill, 2020-09-08) Subbotin, SA; Oliveira, CJ; Álvarez Ortega, Sergio; Desaeger, JA; Crow, W; Overstreet, C; Leahy, R; Vau, S; Inserra, RN
    Populations reviously identified as Aphelenchoides besseyi were studied. Using an integrated approach, the A. besseyi species complex contains several cryptic species: A. besseyi sensu stricto, A. oryzae, A. pseudobesseyi sp. n. and other putative undescribed species. A population from Florida strawberry morphologically fits the A. besseyi of both Christie and Allen and is considered the only representative of this species. A Louisiana rice population fitted the descriptions of A. oryzae of both Yokoo and Fortuner; PUS length was consistently less than one-third of VA. Aphelenchoides oryzae, parasitising rice and other monocots, was re-established based on morphological and molecular datasets. Three populations from Florida ornamental plants (Dryopteris erythrosora, Echinacea sp. and Farfugium japonicum) differed from those of the two above-mentioned species and are described as A. pseudobesseyi sp. n. Populations previously identified as 'A. besseyi' from several countries were considered representatives of this new species, which usually had a large and conspicuous PUS, 8-14 mu m wide and with a length greater than one-third of VA in 40-70% of studied specimens. Morphological variability made separation of A. pseudobesseyi sp. n. from A. oryzae and A. besseyi unreliable without the examination of numerous specimens and molecular analysis.

    Madrid – Lisboa: Dos ciudades proyectadas en la segunda mitad del siglo XX
    (Universidad Complutense de Madrid, 2024-11-27) Zarza-Arribas, Alba; González Cubero, Josefina
    Esta investigación profundiza en la estrecha relación entre arquitectura y cinematografía, mediante una aproximación a la representación de las principales ciudades ibéricas en los noticiarios estatales, promovidos y producidos por los Nuevos Estados de España (1939-1975) y Portugal (1933-1974). La importancia de Madrid y Lisboa en las noticias y reportajes del cine estatal hispano-luso, de su papel como capitales y símbolos de ambas dictaduras y de su elevado crecimiento urbano durante este período justifica su elección como casos de estudio. A través de la mirada construida por el cine oficial los noticiarios documentaron la evolución de ambas metrópolis, de las políticas nacionales de vivienda y las formas de habitar desde la posguerra hasta la sociedad de consumo. Por ello, con un enfoque comparativo, se profundiza en la construcción urbana de las dos ciudades, en la producción cinematográfica estatal ibérica y en la difusión de las ideas y debates arquitectónicos en el cine.

    Morphological and molecular characterization of Xiphinemella esseri Chitwood,1957 (Dorylaimida: Leptonchidae) from Florida, with the first molecular study of the genus
    (Society of Nematologists, 2021-01) Álvarez Ortega, Sergio; Subbotin, SA; Inserra, RN
    A population of Xiphinemella esseri, recently collected under the canopy of associated live oak trees in north Florida, was studied and described with an integrative approach, including the first molecular study of the genus. This Florida population is characterized by its 2.30 to 3.32 mm long body, labial disc well developed, lip region offset by constriction, and 16.5 to 17.5 mu m broad, odontostyle 46 to 49 mu m long with minute aperture, neck 288 to 296 mu m long, pharyngeal expansion occupying 28 to 30% of total neck length, uterus a tripartite tube-like structure, pars refringens vaginae absent, vulva transverse (V = 45.4-49.7%), tail short and rounded (18-28 mu m, c = 94-158, c' = 0.6-0.9), spicules 41 to 45 mu m long, and 8 to 10 irregularly spaced ventromedian supplements bearing hiatus. The phylogenetic analysis inferred from the D2-D3 expansion segments of 28S rRNA gene and 18S rRNA gene sequences showed that X. esseri clustered with other dorylaims from the family Leptonchidae. A brief discussion about the distribution and biological considerations of X. esseri is also provided.
