Inundación y manejo de suelos en la Argentina
No full textLa ocurrencia de inundaciones es un tema que regresa recurrentemente al debate colectivo, en consonancia con la llegada de períodos con lluvias excesivas. Puede afirmarse, en principio, que el tema no es novedoso y fue ya tratado en detalle en una publicación relativamente reciente (Taboada et al., 2009). Lo mismo puede decirse de la ocurrencia de sequías periódicas, esta vez en consonancia con períodos con déficits hídricos. Es que como se afirmó más de una vez, inundaciones y sequías forman parte de un mismo cuadro o proceso, donde actúa ni sólo la obviedad del clima, sino también las características concurrentes de una red de drenaje deficiente para conducir excesos hídricos periódicos y de suelos con limitantes importantes en su perfil para almacenar esos excedentes, pero también para amortiguar las secas periódicas. Mucho de esto ya había sido alertado a fin del siglo XIX por el sabio argentino Florentino Ameghino en sucélebre opúsculo Las secas y las inundaciones en la Provincia de Buenos Aires.Fil: Taboada, Miguel Angel.

A New Record of Scaphytopius Magdalensis: Another Plant Disease Vector in Michigan (Homoptera: Cicadellidae)
No full textExcerpt: Several specimens of Scaphytopius magdalensis (Provancher) were collected by Burger (1966), and brought to the attention of the senior author for verification. This leafhopper, a vector of Blueberry Stunt, is widely distributed in the eastern United States, and southern Ontario and Quebec. This, the first record of a leafhopper virus vector for blueberries in Michigan, increases the list of leafhopper vectors of plant diseases in the state , given in Taboada and Hoffman (1965). to 14
Nuestra América y el islam. La mirada en el tercer milenio
No full text"Eastern history, having barely begun to be written in a critical key, has already given rise to theory and bloody polemic", says the Argentinean historian Hernán G. H. Taboada, who explores in this essay some dimensions of a contemporary, alternative vision of Islam that has been constructed in Our America, outside the influence of the Euronorthamerican model. The most original valuation of this culture has been born, according to the author, from popular re-elaborations of Latin Americans of Arab origin, from some of their literary developments, and from their own propaganda."La historia del orientalismo apenas ha comenzado a ser escrita en clave crítica y ya ha suscitado teoría y polémica encarnizada", dice el historiador argentino Hernán G. H. Taboada, quien pretende en este ensayo explorar algunas dimensiones de la visión contemporánea y alternativa del Islam que se ha ido construyendo en Nuestra América, más allá de la influencia del modelo euronorteamericano. La valoración más original de esta cultura ha ido naciendo, según el autor, a partir de las reelaboraciones populares, algunos desarrollos literarios y de la propia propaganda de latinoamericanos de origen árabe

Body covered by long and erect dense yellowish setae. Head (Fig. 1D): Frons transverse, smooth and glabrous centrally, laterally finely punctate with short, sub-erect, sparse, whitish setae. Vertex concave between antennal tubercles, with microrugosities and with abundant fine punctures close to margins. Coronal suture indistinct. Antennal tubercles glabrous on base, acute apically. Upper eye lobes with five rows of ommatidia. Distance between upper eye lobes about 2.5 times length of scape; in frontal view, distance between lower eye lobes ⅔ the length of scape. Genae moderately short, distinctly acute at apex. Frontoclypeal sulcus indistinct. Clypeus truncate, yellowish laterally. Labrum rounded at distal margin, yellowish laterally, with yellowish setae. Mandibles with long whitish setae, glabrous at apex. Antennae 11-segmented; antennomeres III-VIII armed, with dense and decumbent yellowish setae at outer face and long and erect setae at inner face. Apical spines of antennomere III and IV longer than the apex diameter of respective antennomeres (broken apically); apical spine of antennomere V about ¼ of length of its antennomere; apical spine of antennomere VI about 0.2 times length of its antennomere; apical spine of antennomere VII with 0.075 times length of antennomere; antennomere VIII with spicule at outer apex. Scape gradually dilated toward apex.

Type material: Holotype, COLOMBIA, Bolívar: Archipiélago de San Bernardo, Isla Tintipán (09°47′40.39″N, 75°50′43.35″W, 0 m.s.n.m) (Fig. 2), 1 ♀, 24.III.2005, colecta manual, P. Duque col. (MEPB). Etymology: The species epithet is in honor of Ruth Verona Anaya, mother of the first author, for your love, understanding and constant support. Remarks: Stizocera ruthveronae sp. nov., is similar to S. asyka Galileo & Martins 2004, S. nigroflava Zajciw 1965 and S. tristis (Guérin-Méneville, 1844) by the body covered of long and dense setae; integument color and meso and metafemora pedunculate and bispinose. Stizocera ruthveronae sp. nov., differs by antennomeres III-VIII armed (antennomeres III-V armed in those species, in S. nigroflava the antennomere VI can be also armed) and pronotum with four gibbosities poorly elevated. Other characteristics used to differentiate S. ruthveronae sp. nov. can be observed in the following key.Published as part of Taboada-Verona, Carlos & Botero, Juan Pablo, 2020, A new species of Stizocera Audinet-Serville, 1834 (Coleoptera: Cerambycidae) from Colombia with an updated key to species of the genus and new geographical records in Cerambycinae, pp. 1-8 in Papéis Avulsos de Zoologia 60 on pages 1-3, DOI: 10.11606/1807-0205/2020.60.46, http://zenodo.org/record/461389
