No full textSabatieria fidelis sp. n. (Figures 5, 6, 7, 8; Table 1) Material Studied: 2 males, 2 females. Type material: Male holotype, slide MNRJ 320. Female paratype, slide MNRJ 321; 1 male, slide 96 NM LMZOO-UFPE, 1 female, slide 97 NM LMZOO-UFPE. Type locality: Male holotype, station no. 54, 750 m depth, collected in May 2002. Other localities: Female paratype, station no. 41, 1222 m depth, collected in May 2002; male paratype, station no. 35, 916 m depth, collected in May 2002; female paratype, station no. 74, 750 m depth, collected in November 2002 (cf. Appendix 1). Etymology. The species name is the Latin fidelis = faithful, because the specimens have all the characteristics that are common to Sabatieria species, and the new features are not easy to see. Description. holotype: Cylindrical body, medium-sized, attenuated at both ends. Cuticle with transverse rows of dots, and lateral differentiation with larger and more widely spaced dots, irregularly arranged. Head slightly set off by constriction in the cephalic setae region, and with anterior sensilla arranged in three crowns: six minute internal labial papillae, six external labial papillae and four cephalic setae. Buccal cavity cupshaped. Amphidial fovea spiral, with 2 1 / 4 turns. Pharynx slightly clavate, gradually expanding towards the posterior end, but without distinct bulb. Cardia short and round. Nerve ring slender, located very close to middle of pharynx and anterior to secretory-excretory pore. Cellular body of ventral gland at level of posterior end of pharynx and beginning of intestine, with secretory pore in middle of pharynx. Male reproductive system diorchic, with opposed and outstretched testes. Anterior testis situated on the left and posterior testis on the right side of the intestine. Slender short paired spicules, similar in length and width and slightly curved ventrally; proximal half of septum and distal part with ventrally directed dropper-shaped tip. Several glandular cells are arranged around the spicules. Gubernaculum small, cuticularized, v-shaped in distal part, measuring 16 µm, and with narrow cuticularized apophysis of length 22 µm. Minute pore-like pre-cloacal supplements present, easily overlooked; but unfortunately the specimens are more ventrally positioned without a clear view of the number of them. Three pairs of ejaculatory glands anterior to the cloaca. Spermatozoa oval, 21 µm long. Conico-cylindrical tail with three caudal glands, ending in a spinneret. Three setae on the tail tip, measuring 3 µm. Female Paratype: The females are similar to males except for the longer total length, shorter tail and spiral amphidial fovea with 2 ¼– 3 turns. Reproductive system didelphic-amphidelphic; with outstretched ovaries. Anterior ovary to the left and posterior ovary to the right of the intestine, and distal part of the uterus with oocyte. Vulva at mid-body, vagina thin-walled; pars proximalis vaginae (= vagina uterina) surrounded by a well-developed constricting muscle. Granular vaginal glands present at the pars distalis vaginae. Oocytes 44–53 µm long. Diagnosis. Sabatieria fidelis sp. n. can be differentiated by its short outstretched testes, the spicules with dropper-shaped tips and directed ventrally, the gubernaculum with a cuticularized v-shape on the distal part, and the short cephalic and somatic setae. Discussion. In relation to Sabatieria pulchra, the similar characteristics are the number of amphidial fovea turns in females, total length, maximum diameter and spicule length. Sabatieria fidelis sp. n. differs in relation to the number of turns of the amphidial fovea in males (Sabatieria pulchra with 2 ¾– 3), absence of three glands in the pharyngeal region, and the proximal parts of the spicules in S. pulchra are more inflated than in Sabatieria fidelis sp. n. Another characteristic is the sexual dimorphism in Sabatieria fidelis sp. n.: females have a shorter tail and more turns in the amphidial fovea. Sabatieria fidelis sp. n. is similar to Sabatieria falcifera with respect to the short cervical setae, number of turns of the amphidial fovea in the female (2.5 in S. fidelis sp. n. and in S. falcifera) and spicule length (62 µm in S. fidelis sp. n. versus 66.5 µm in S. falcifera). It can be distinguished by the cephalic setae length (3–3.7 in S. fidelis sp. n. versus 7 µm in S. falcifera), length of the gubernaculum apophysis (22 µm in S. fidelis sp. n. versus 29 µm S. falcifera), number of turns of amphidial fovea in the male (2.5 in S. fidelis sp. n. versus 2.7–3 in S. falcifera). Sabatieria fidelis sp. n. also resembles Sabatieria praedatrix in maximum diameter (64.5 in S. fidelis sp. n. versus 67 µm in S. praedatrix) and the length of somatic setae. It can be differentiated by the de Man indexes a and c (a = 26.3–34.8; c = 13.8–20.9 in S. fidelis versus a = 50–55; c = 13.5–14 in S. praedatrix). In relation to Sabatieria vasicola, this new species has the same values of de Man indexes a, b and c (a = 26.3–34.8; b = 7.4–10.9; c = 13.8–20.9 in S. fidelis versus a = 26.6–32.2; b = 7.5–9.3; c = 9.1–14.7 in S. vasicola), but can be distinguished by the length of the cephalic setae (3–3.7 µm in S. fidelis sp. n. versus 6–8 µm in S. vasicola), spicule length (62–68 µm in S. fidelis sp. n. versus 72–82 µm in S. vasicola), apophysis length (22 µm in S. fidelis sp. n. versus 33–34 µm in S. vasicola) and tail length (90–150 µm in S. fidelis sp. n. versus 173–220 µm in S. vasicola).Published as part of Botelho, Alessandra Prates, Silva, Maria Cristina Da, Sobral, Luciana Davina Tosta & Fonsêca-Genevois, Verônica Gomes, 2009, Two new species of Sabatieria Rouville (Nematoda: Comesomatidae) with conical-cylindrical tails, from Campos Basin, Rio de Janeiro, Brazil *, pp. 82-98 in Zootaxa 2096 on pages 91-96, DOI: 10.5281/zenodo.18771

Selected letters of Alessandra Strozzi
No full textThe letters of Alessandra Strozzi provide a vivid and spirited portrayal of life in fifteenth-century Florence. Among the richest autobiographical materials to survive from the Italian Renaissance, the letters reveal a woman who fought stubbornly to preserve her family's property and position in adverse circumstances, and who was an acute observer of Medicean society. Her letters speak of political and social status, of the concept of honor, and of the harshness of life, including the plague and the loss of children. They are also a guide to Alessandra's inner life over a period of twenty-three years, revealing the pain and sorrow, and, more rarely, the joy and triumph, with which she responded to the events unfolding around her.This edition includes translations, in full or in part, of 35 of the 73 extant letters. The selections carry forward the story of Alessandra's life and illustrate the range of attitudes, concerns, and activities which were characteristic of their author
Challenging the author: Gavin Douglas's Eneados
No full textGavin Douglas’s Eneados, a translation into the “Scottis” tongue of Virgil’s Aeneid, completed in 1513 and first published in London in 1553, presents, as well as the translation of the additional thirteenth book by Maphaeus Vegius, original prologues and marginal notes to the text, rubrics and articulate conclusive material. The present paper analyses this complex paratext as evidence of Douglas’s almost philological attention to the original and his preoccupation with a faithful reproduction; it is also suggested that the models for his organization of the commentary might be both medieval (i.e., manuscripts such as Petrarch’s Virgilius Ambrosianus) and early modern, as in the case of editions of classical works: the most apt example being Jodocus Badius Ascensius’ edition of the Aeneid, printed in 1501. The Eneados thus stands on the threshold between manuscript and print, and might have indicated new possibilities of use of the printing medium in Scotland, and of the value of the translation of a classical text, had history not intervened with the Scottish defeat at Flodden Fields in 1513, which put a temporary stop both to the circulation of the Eneados and to the development of Scottish printing

Dynamics of soil seed bank and germination of native and invasive grasses of Cerrado
No full textEspécies invasoras são aquelas capazes de se estabelecer em áreas além de sua ocorrência natural, ultrapassando barreiras geográficas e constituindo novas populações viáveis. A introdução de gramíneas africanas no Cerrado, como Melinis minutiflora P. Beauv e Urochloa brizantha (Stapf) R.D. Webster, pode levar a uma baixa heterogeneidade do sistema, deixando-o mais suscetível a distúrbios ambientais, alterando o equilíbrio da comunidade e os serviços ecossistêmicos. Em sistemas frequentemente perturbados, clareiras são criadas na paisagem e novas espécies são recrutadas para colonizar o espaço aberto, processo esse regido pelo nicho da regeneração. Espera-se que estes nichos se sobressaiam nas espécies invasoras em relação às espécies nativas, conferindo-lhes vantagens adaptativas na colonização desses espaços. Dessa maneira, o objetivo do estudo foi avaliar a dinâmica do banco de sementes de gramíneas em áreas com e sem invasão biológica, além de avaliar diferentes fatores que influenciam a germinação de gramíneas nativas. A área de estudo está inserida na Estação Ecológica de Itirapina, onde até 1998 havia uma plantação de Pinus caribaea, a qual foi removida e desde então a área está sob regeneração natural, sem interferência, com alto grau de invasão por gramíneas africanas. No primeiro capítulo, as amostras de solo foram coletadas nas parcelas experimentais controle do projeto da Profa. Dra. Alessandra Fidelis (FAPESP 2015/06743-0), delineado então parcelas com três tratamentos: dominada por uma das duas espécies invasoras, Melinis minutiflora e Urochloa brizantha, e parcelas com domínio de vegetação nativa (4parcelas/tratamento= 12 unidades amostrais). No segundo capítulo, as sementes de gramíneas nativas foram coletadas na Estação Ecológica de Itirapina e na Reserva Natural Serra do Tombador, triadas em laboratório e submetidas a tratamentos de flutuação de temperatura, simulando a oscilação de temperatura diária sobre a superfície do solo, e choques de temperatura simulando a passagem do fogo. O conhecimento mais detalhado sobre o banco de sementes em áreas invadidas é fundamental para elaboração de práticas de controle e manejo dessas espécies. Além disso, a germinação e viabilidade das sementes de gramíneas nativas são fatores importantes tanto para elucidar a regeneração natural via semente, compreendendo processos ecológicos relacionados à quebra da dormência fisiológica, quanto para aplicação de métodos físicos de restauração do Cerrado, como a semeadura direta.Invasive species are those capable of establishing themselves in areas beyond its natural occurrence, surpassing geographical barriers and constituting new populations. The introduction of African grasses in Cerrado, Melinis minutiflora P. Beauv and Urochloa brizantha (Stapf) R.D. Webster, may low heterogeneity of the system, making it more susceptible to altering the balance of the community and ecosystems. In frequently disturbed systems, clearings are created in the landscape and new species are recruited to colonize the open space, which is governed by the regeneration niche. These niches are expected to be better in invasive species in relation to native species, giving them adaptive advantages in the colonization of these spaces. In this way, the objective of the study was to evaluate the dynamics of grasslands in areas with and without biological invasion, in addition to evaluating different factors that influence the germination of native grasses. The study area is located in the Estação Ecológica de Itirapina, where until 1998 there was a plantation of Pinus caribaea, which has been removed and since then the area is under natural regeneration, without interference, with a high invasion of Urochloa brizantha and Melinis minutiflora. In the first chapter, the soil samples were collected in the control plots of the project of Profa. Dr. Alessandra Fidelis (FAPESP 2015 / 06743-0), outlined then plots with three treatments: dominated by one of the two invasive species, Urochloa brizantha and Melinis minutiflora, and plots with dominance of native vegetation (4plots / treatment = 12 sample units). In the second chapter, grass seeds were collected at Estação Ecológica de Itirapina and in Reserva Natural Serra do Tombador, triads in the laboratory and submitted to treatments of temperature fluctuation, simulating the daily temperature oscillation on the soil surface, and heat shock simulating the passage of fire. More detailed knowledge about the soil seed bank in invaded areas is fundamental for the elaboration of practices of control and management of these species. In addition, the germination and viability of native grass seeds are important factors both to elucidate the natural regeneration through seed, comprising ecological processes related to break physiological dormancy of seed, and for application of physical methods of restoration of Cerrado, such as direct sowing.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES
