Spider diversity (Arachnida: Araneae) in Atlantic Forest areas at Pedra Branca State Park, Rio de Janeiro, Brazil

BACKGROUND: There has never been any published work about the diversity of spiders in the city of Rio de Janeiro using analytical tools to measure diversity. The only available records for spider communities in nearby areas indicate 308 species in the National Park of Tijuca and 159 species in Marapendi Municipal Park. These numbers are based on a rapid survey and on an one-year survey respectively. NEW INFORMATION: This study provides a more thorough understanding of how the spider species are distributed at Pedra Branca State Park. We report a total of 14,626 spider specimens recorded from this park, representing 49 families and 373 species or morphospecies, including at least 73 undescribed species. Also, the distribution range of 45 species was expanded, and species accumulation curves estimate that there is a minimum of 388 (Bootstrap) and a maximum of 468 species (Jackknife2) for the sampled areas. These estimates indicates that the spider diversity may be higher than observed.Fil: Castanheira, Pedro. Universidade Federal do Rio de Janeiro; BrasilFil: Pérez González, Abel.

Crónicas sobre el desastre en Río de Janeiro

La noche del 2 de septiembre de 2018 se inició un trágico incendio que destruyó el histórico edificio que ocupaba el Museo Nacional de Río de Janeiro (MNRJ), nada menos que el palacio São Cristóvão que fuera la antigua morada de la familia imperial brasileña localizada en la Quinta da Boa Vista en pleno corazón de la metrópoli carioca. En lo que fue tal vez la mayor pérdida de patrimonio científico de los últimos 50 años, el fuego se llevó consigo una enorme cantidad de especímenes representativos de la biodiversidad de Brasil y resto de Latinoamérica junto con artefactos culturales calculado en unos 20 millones de piezas. Este incendio consumó la pesadilla que pervive en la intimidad de todas las instituciones que actúan como repositorio, vale decir: la perdida en apenas unas horas de todo el trabajo y la información de muchas décadas fruto del trabajo de varias generaciones de científicos.Fil: Mulieri, Pablo Ricardo.

Análisis terminológico de préstamos en la revista Computer Hoy, Lima 2018

La presente investigación tiene como objetivo principal analizar cómo se manifiesta la formación de préstamos en la revista Computer Hoy, Lima 2018. Esta investigación cualitativa, de naturaleza netamente descriptiva, utilizó como muestra 25 términos de 2 ediciones de julio de 2017 de la revista Computer Hoy; y se analizaron términos de textos informáticos y tecnológicos. El instrumento utilizado fue la ficha de análisis terminológico que se aplicó para realizar el análisis de préstamos puros, préstamos creación hibrida, y préstamos intrusión fonológica. Los resultados mostraron que de los tres tipos de préstamos, los préstamos puros fueron los más comunes, y los préstamos por creación híbrida, y préstamos por intrusión fonológica no tuvieron incidencia. En el conjunto de préstamos encontrados se han observado sustantivos, verbos y adjetivos, provenientes de la lengua origen

Levels of heavy metals composition in atmospheric aerosol samples and the influence of african episodes

Particulate matter pollution is a serious environmental issue mainly due to the presence of toxic substances and trace metals in the atmosphere from a variety of pollution emission sources. Information about aerosol composition and their sources especially during pollution events can be further used to establish strategies for the reduction of particulate matter concentration. The objective in the present study was to analyse variations in total suspended particle (TSP) mass concentration and heavy metal components for evaluating the atmospheric loadings of substances with different sources as well as to further examine the relationship between the occurrence of African dust intrusions and metallic species concentrations at our coastal station located in South Spain. Non-destructive Wavelength-Dispersive X-Ray Fluorescence (WDXRF) analysis has been applied for the determination of multi-element contents of atmospheric particulate matter.Universidad de Málaga.

Fully-Convolutional Denoising Auto-Encoders for NILM in Large Non-Residential Buildings

[EN] Great concern regarding energy efficiency has led the research community to develop approaches which enhance the energy awareness by means of insightful representations. An example of intuitive energy representation is the parts-based representation provided by Non-Intrusive Load Monitoring (NILM) techniques which decompose non-measured individual loads from a single total measurement of the installation, resulting in more detailed information about how the energy is spent along the electrical system. Although there are previous works that have achieved important results on NILM, the majority of the NILM systems were only validated in residential buildings, leaving a niche for the study of energy disaggregation in non-residential buildings, which present a specific behavior. In this paper, we suggest a novel fully-convolutional denoising auto-encoder architecture (FCN-dAE) as a convenient NILM system for large non-residential buildings, and it is compared, in terms of particular aspects of large buildings, to previous denoising auto-encoder approaches (dAE) using real electrical consumption from a hospital facility. Furthermore, by means of three use cases, we show that our approach provides extra helpful funcionalities for energy management tasks in large buildings, such as meter replacement, gap filling or novelty detection.SIThis work was supported by the Principado de Asturias Government through the Predoctoral Grant “Severo Ochoa.” Paper no.

Cuban spider genus Ciboneya

23 p. : ill., 1 map ; 26 cm.Includes bibliographical references (p. 23).Four species of Ciboneya Pérez, n. gen. are described from western Cuba: C. nuriae, n. sp. from La Habana and Pinar del Rio provinces, C. odilere, n. sp., C. parva, n. sp., and C. antraia, n. sp. from Pinar del Rio Province. The species share apophyses on the male cheliceral fangs, corresponding pockets or modified areas on the female epigynum, and several details of the male pedipalps. Vertical hairs on the tibiae and metatarsi of the male legs and a retrolateral coxa apophysis on the male palp place the genus closer to other Central or South American genera of the New World clade of pholcids, but the exact sister group is obscure. The spiders live in the leaf litter and under rocks in humid forests, or near the floor in caves. The females of C. antraia show a remarkable dimorphism in their genitalia, with rare intermediate forms. The possibly more frequent occurrence of such a dimorphism and the probable bias toward reporting it as two different species are discussed

Who is going to describe our biodiversity?: The taxonomic impediment faced to the Nagoya Protocol and the current regulations

La vigencia del Protocolo de Nagoya sobre acceso a los recursos genéticos y participación en los beneficios ha impulsado, desde 2014, normativas nacionales y provinciales en Argentina, que regulan diversas actividades, entre ellas la colecta y el traslado de especímenes con fines científicos. En esta nota analizamos las consecuencias negativas sobre la tarea taxonómica que derivan de una aplicación de las normativas sin la necesaria distinción entre actividades con fines comerciales e investigación sin fines de lucro, y de agobiantes exigencias burocráticas. Esto genera serios obstáculos a la descripción de la biodiversidad y agrava el impedimento taxonómico, en franca contradicción con el espíritu del Convenio sobre Diversidad Biológica (CBD). Se sugiere la efectiva simplificación de las medidas que garanticen el acceso a material biológico para trabajos taxonómicos, en especial en sus aspectos de colecta en campo y los procedimientos aduaneros para la colaboración internacional.The entry in force of the Nagoya Protocol on access on genetic resources and benefit sharing has triggered, since 2014, national and provincial regulations in Argentina, which rule different activities, among them the collecting and transport of specimens with scientific purposes. In this contribution we analyze the negative consequences on the taxonomic work, derived from applying the rules without distinguishing activities with commercial use and non-profit research, and from overwhelming bureaucratic requirements. All this generates serious obstacles to the description of the biodiversity and worsens the taxonomic impediment, in contradiction to the spirit of the Convention on Biological Diversity (CBD). It is suggested that measures should be effective to guarantee the simplified access on biological materials for taxonomists, especially relative to the stages of collecting in field and customs procedures for international collaboration.Fil: Acosta, Luis Eduardo.

Harvestmen in the first twenty years: A scientometric analysis of Zootaxa’s contribution to opilionology (Arthropoda, Arachnida, Opiliones)

In its first twenty years of existence Zootaxa has been widely utilized among researchers of Opiliones, mainly those coming from Latin American countries, principally Brazil. During 2003–2020, a total of 141 papers on Opiliones were published in Zootaxa (no papers were published on Opiliones in the first two years, 2001–2002). The journal has greatly facilitated the dissemination of knowledge on Opiliones, especially with respect to the taxonomy and systematics of harvestmen from the Neotropical Realm. Those 141 papers in Zootaxa include almost a quarter (191) of the new species of Opiliones described between 2001 and 2020, as well as 112 new synonymies. Additionally, 27 of those papers proposed 182 new or restored combinations. A total of 108 authors working in 25 countries have contributed papers to Zootaxa focusing on Opiliones. There is clearly a predominance for collaborative contributions with more than twice as many papers authored by two or more authors compared to single-author publications. In general, the majority of papers deal within the local biogeographic realm (where the lead author resides). Studies of harvestmen from seven of the eight biogeographic realms were published in Zootaxa during 2003–2020. The largest portion of these contributions were by far focused on the Neotropical opiliofauna, but Australasian, Nearctic, Indomalayan, Palearctic, Afrotropical and Antarctic opiliofauna are covered as well. No papers on Opiliones have been published in Zootaxa by authors representing countries in Africa. We also recognize a strong gender bias in authorship and the current composition of Opiliones subject editors. We will strive to create an inclusive environment and aim to promote diversity of scientists who study Opiliones.Fil: Pérez González, Abel. Consejo Nacional de Investigaciones Científicas y Técnicas.
