Chromosome numbers in Hieracium and Pilosella species (Asteraceae) from the Iberian Peninsula and the Balearic Islands
2007
Mitotic chromosome numbers are reported from 16 Hieracium and two Pilosella species from the Iberian Peninsula and the Balearic Islands that are little known cytogenetically. The chromosome numbers of Hieracium aragonense Scheele (2 n = 27, 36), H. compositum Lapeyr. (2 n = 27), H. murcandidum G. Mateo (2 n = 27), H. spathulatum Scheele (2 n = 27), H. segurae Mateo (2 n = 27), H. teruelanum Mateo (2 n = 27), H. valentinum Pau (2 n = 27), Pilosella pseudovahlii (De Retz) Mateo (2 n = 18), and P. tardans (Peter) Sojak (2 n = 36) were determined for the first time. New cytotypes were detected in H. cordifolium Lapeyr. (2 n = 27) and H. loscosianum Scheele (2 n = 36). The karyo- type of the stu…
Karyology of Limonium (Plumbaginaceae) species from the Balearic Islands and the western Iberian Peninsula
2007
Somatic chromosome numbers, conventional karyotype features and idiograms are reported for 27 Limonium species inhabiting the Western Mediterranean basin (Iberian Peninsula and the Balearic Islands). The chromosome numbers of Limonium barceloi (2n = 36), L. ejulabilis (2n = 24), L. inexpectans (2n = 26), L. interjectum (2n = 24), and L. scopulorum (2n = 25) were determined for the first time. In addition, new aneuploid and/or polyploid cytotypes are reported in L. alcudianum (2n = 26), L. bonafei (2n = 26), L. camposanum (2n = 26), L. companyonis (2n = 26), L. dufourii (2n = 26), L. geronense (2n = 36), L. marisolii (2n = 54), L. migjornense (2n = 50), and L. pseudodictyocladon (2n = 16).

<i>Limonium carvalhoi (Plumbaginaceae)</i>, a new endemic species from the Balearic Islands
1998
ROSSELLO, J.A., L. SAEZ & A.C. CARVALHO (1998). Limonium carvalhoi (Plumbaginaceae), a new endemic species from the Balearic Islands. Anales Jard. Bot. Madrid 56(1): 23-31. Limonium carvalhoi Rossello & L. Saez is described from a single salt marsh locality in southwest Majorca. Morphologically, L. carvalhoi is ciose to L. inexpectans, L. migjornense and L. magallufianum , all Balearic endemics. The new species has an apomictic breeding system and shows a single pollen/stigma combination (B/papillate type). Chromosome number ranges from 2n = 24 to 2n = 26. Based on the occurrence of a long metacentric chromosome in all cells examined, it is suggested that the original chromosome complement …
<p><strong>Type designation of the Lamarck’s name <em>Buxus balearica</em> (<em>Buxaceae</em>)</strong><…
2019
The Lamarck’s name Buxus balearica is discussed and neotypified from a specimen preserved at MA collected in Mallorca (Balearic Islands, Spain). In addition, the lectotypes of B. longifolia and B. balearica f. granatensis, currently treated as two heterotypic synonyms of B. balearica, are designated from original material preserved at G-BOIS and MA, respectively
Boulevard Barbès: conflitto urbano e conflitto mediatico
2020
Questo studio esplora alcune modalità attraverso le quali il conflitto urbano può essere "preparato" e "percepito" attraverso la costruzione mediatica (strategie discorsive e retoriche), seppure non apertamente. A partire da una ricerca sul campo effettuata a Parigi, nel quartiere Barbès (una delle Zone di Sicurezza Prioritarie francesi), in occasione della vittoria della nazionale di calcio algerina durante i mondiali del 2014, lo studio si concentra sul modo in cui tifosi e residenti da un lato e polizia dall'altro costruiscono multistratificate retoriche del conflitto. Abbinando anche l'analisi di testi online (testate giornalistiche e blog) viene studiata la discrasia tra mediatizzazion…
Barbès, Parigi: conflitto urbano e conflitto mediatico
2020
Il capitolo propone una riflessione sul conflitto urbano da una prospettiva geografica, a partire da un caso studio rilevato nel 2014 nel quartiere Barbès a Parigi, dove, in occasione della qualificazione agli ottavi di finale della nazionale algerina ai Mondiali di calcio disputati in Brasile, molti tifosi si ritrovarono per festeggiare il risultato nel corso di un’intera notte. L’evento, giudicato a rischio dalle autorità, fece scattare un grande spiegamento delle forze dell’ordine. Si trovarono così contrapposte due dialettiche, potenzialmente conflittuali. Non si arrivò allo scontro e, per usare i termini di Barthes, i due “discorsi cittadini” si collocarono su due piani non collidenti.…
Predicting soil loss in central and south Italy with a single USLE-MM model
2018
Purpose: The USLE-MM estimates event normalized plot soil loss, Ae,N, by an erosivity term given by the runoff coefficient, QR, times the single-storm erosion index, EI30, raised to an exponent b1> 1. This modeling scheme is based on an expected power relationship, with an exponent greater than one, between event sediment concentration, Ce, and the EI30/Pe(Pe= rainfall depth) term. In this investigation, carried out at the three experimental sites of Bagnara, Masse, and Sparacia, in Italy; the soundness of the USLE-MM scheme was tested. Materials and methods: A total of 1192 (Ae,N, QREI30) data pairs were used to parameterize the model both locally and considering all sites simultaneously. …
Los Urrea y la Revuelta de L'Alcalaten de diciembre de 1440
1995
A fines de 1440, se produjo en la Tinença d'Alcalatén, señorío perteneciente a los Urrea (familia de poderosos magnates de origen aragonés) una sublevación en contra de la autoridad real. Culminaba así un largo enfrentamiento entre los señores de la baronía y sus acreedores censalistas, durante el cual se discutió tanto la validez de la aplicación de los Fueros de Aragón en el reino de Valencia como la supremacía de la autoridad real sobre la baronal.
Usefulness of omp1 restriction mapping for avian Chlamydia psittaci isolate differentiation
1995
Abstract Sixty-five avian Chlamydia psittaci isolates collected worldwide, including 27 previously characterized reference strains, were analysed by restriction mapping of the major outer membrane protein gene ( omp1 ) obtained after DMA amplification by PCR. They were compared to 2 ruminant isolates, a feline pneumonitis and a guinea pig inclusion conjunctivitis (GPIC) isolate. According to their omp1 restriction patterns, avian strains were heterogeneous in that they exhibited 6 and 4 distinct patterns using Alu I and Mbo II restriction enzymes, respectively, thus defining 7 groups. However, 84% of the studied strains belonged to groups 1 to 4, which share a specific fragment triplet of 4…
The development of fundamental motor skills of four‐ to five‐year‐old preschool children and the effects of a preschool physical education curriculum
2011
Altogether 38 girls and 46 boys aged four to five years were studied to analyse the linear and non‐linear development of fundamental motor skills. The children were grouped into one experimental and one control group to study the effects of an eight‐month preschool physical education curriculum. In the course of one year, the balance skills of the girls, the running speed of the boys and the standing broad‐jump and manipulative skills of both genders progressed linearly according to the children's age. Two weekly 45‐minute physical education lessons instructed by preschool teachers promoted the linear development of the girls' standing broad‐jump and non‐linear development of the boys' runn…
