Three new species of the subgenus Neoribates (Neoribates) (Acari, Oribatida, Parakalummidae) from Nepal
2014
Three new parakalummid mites of the subgenus Neoribates (Neoribates), N. (N.) parabulanovae sp. n., N. (N.) paramacrosacculatus sp. n. and N. (N.) pararotundus sp. n., are described from Nepalese soils. Neoribates (Neoribates) parabulanovae sp. n. is morphologically most similar to N. (N.) bulanovae Grishina, 2009, N. (N.) rotundus Aoki, 1982 and N. (N.) setiger Balogh & Mahunka, 1978, however, it differs from N. (N.) bulanovae by the body length, body and leg integument, morphology of bothridial setae, absence of aggenital setae, length of interlamellar setae and location of adanal setae ad3; from N. (N.) rotundus by the body size, body integument, morphology of bothridial setae and le…
Revision of New World Species of the Shore-fly Subgenus Allotrichoma Becker of the Genus Allotrichoma with Description of the Subgenus Neotrichoma (D…
2012
The New World species of the subgenera Allotrichoma Becker and Neotrichoma (new subgenus) are revised, including a phylogenetic analysis of the species groups and subgenera within the genus Allotrichoma. For phylogenetic perspective and to document the monophyly of the genus Allotrichoma and its included subgenera and species groups, we also provide a cladistic analysis of genera within the tribe Hecamedini. The ingroup included seven exemplar congeners from within Allotrichoma. Outgroup sampling included exemplars of other genera within Hecamedini and from the putative sister group, Lipochaetini, and to root the analysis, we used an exemplar of the tribe Discocerinini. Analyses with succes…
Diversity, ecology and biogeography of Antarctic benthic hydrozoans: the Weddell Sea and the Scotia Arc as study cases
2017
Introducció: Les comunitats bentòniques que es desenvolupen a les aigües antàrtiques són altament singulars com a resultat d’un ambient relativament estable i aïllat. Tal aïllament és degut, entre altres factors, a la presència de la convergència Antàrtica, una forta barrera (o filtre) de temperatura i salinitat, que circumscriu de forma efectiva un dels ecosistemes marins més discrets i isolats geogràficament. Els factors abans esmentats han jugat un paper important en el desenvolupament d'un dels ecosistemes més rics del món pel que respecta a diversitat de fauna marina sèssil. Així doncs, la plataforma Antàrtica, més profunda que qualsevol altra plataforma continental, està constituïda p…
New western Palaearctic Dinotrema species with mesoscutal pit and only medially sculptured propodeum (Hymenoptera, Braconidae, Alysiinae)
2013
Descriptions of four new species of the genus Dinotrema Foerster with a mesoscutal pit and only medially sculptured propodeum are given. Dinotrema alysiae sp. n. (Denmark, England, Netherlands, Spain), D. paramicum sp. n. (Denmark, Finland), D. tirolense sp. n. (Italy) and D. valvulatum sp. n. (Denmark, Italy).
Notes on the genus Rasilinus Mazur, 2016 (Curculionidae: Curculioninae, Eugnomini), with the description of a new species from New Caledonia
2017
New data on the genus Rasilinus (Curculioninae, Eugnomini) are provided, including the description of a new species—Rasilinus bifasciatus sp. n., from New Caledonia. Illustrations and SEM photographs of male external morphology, terminalia, and a colour habitus of the adult of the new species are provided.
The first record of the genus Fulvius Stål, 1862 (Heteroptera: Miridae: Cylapinae) from continental China with description of a new species
2020
A new species of the genus Fulvius Stål, 1862 (Heteroptera: Miridae: Cylapinae: Fulviini) is described based on a couple of specimens collected in Yunnan Province in SW China. The genus is also reported from continental China for the first time. Detailed illustrations of the tarsi, the distribution of trichobothria on the metafemur and male genitalia are given, and an image of the dorsal habitus is presented.
New data on Siciliaria septemplicata (R.A. Philippi, 1836) complex (Gastropoda Clausiliidae) from the surroundings of Palermo (NW-Sicily, Italy)
2023
Siciliaria septemplicata (R.A. Philippi, 1836) (Gastropoda Clausiliidae) endemic from northwestern Sicily (Italy) is revised, using shell and genital characters. The diversity of the species complex, the taxonomic history, faunal data and distributional relationships are examined. Siciliaria septemplicata vincentii n. ssp. and S. septemplicata mariastellae n. ssp. from the surroundings of Palermo are here described
Umani e animali nell’antropologia socioculturale contemporanea
2022
In the chapter, I show the connection between the ways in which the nineteenth-twentieth century sociocultural anthropologists became interested in the study of human-animal relationships and the dominant conceptions about the relationship between humanity and animality in philosophical and scientific thought of these two centuries. Till the last part of the twentieth century non-human animals were considered by anthropologists mainly as material and/or symbolic resources for the reproduction of humans and their social orders. This view paralleled the dominant vision in Western modern philosophical and scientific thought in which non-human animals were assimilated to mindless machines belon…
CHEMICAL INVESTIGATION OF THE INVASIVE ALGA CAULERPA TAXIFOLIA VAR. DISTICHOPHYLLA FROM SICILIAN COASTS
2018
Biological invasions by non-indigenous species have been widely recognized among the most important threats to the integrity of Mediterranean ecosystems, often resulting in huge economic and societal impacts. The success of non-indigenous macrophytes in the new range may be due to a variety of factors such as their vegetative reproductive strategy and synthesis of toxic compounds. These toxic compounds may influence native consumers by reducing their performance with negative implications for their overall grazing activity and, ultimately, for their ability to control the spread of the invasive algae in the new area. In particular, the invasive algae Caulerpa taxifolia (Vahl) C. Agardh (Ct)…
Diseño y optimización de liposomas para un uso como sistema de suministro de nutrientes a larvas de peces marinos.
2006
Las deficiencias nutricionales de las presas vivas usadas como primer alimento exógeno en el cultivo de larvas de peces marinos hacen necesaria la suplementación de las dietas con nutrientes que satisfagan los requerimientos de las larvas. Los liposomas constituyen una herramienta con gran potencial ya que pueden formularse con nutrientes hidrosolubles disueltos en su fase acuosa y liposolubles inmersos en el ambiente lipofílico entre las cadenas de ácidos grasos de los fosfolípidos. Este estudio valora el empleo de liposomas para suministrar nutrientes a larvas de peces marinos a través de dos vías. La primera plantea la vehiculación de nutrientes a larvas de peces a través de la bioencaps…
