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…

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.
Notes on Shore Flies (Diptera: Ephydridae) from Finland and north-western Russia
2015
The recent checklist of the Ephydridae of Finland by Zatwarnicki and Kahanpää (2014) mentioned 13 ephydrid species as new for Finland without further details. This paper presents detailed records for those species and a few other species of interest. Four species are recorded for the first time from Russia. Trimerina indistincta Krivosheina, 2004 is herein considered as a new junior synonym of Trimerina microchaeta Hendel, 1932, syn. nov.
Notes on Selected Genera of Shore Flies (Diptera: Ephydridae), with Removals to Drosophilidae, Heleomyzidae and Milichiidae
2022
The following new taxonomic changes in nine tribes of Ephydridae are proposed: status at species level: Ditrichophora amoena (Duda, 1942); 2 resurrections from synonymy: Ptilomyia madeirensis Stuke, 2012, bona species, and P. orsovana (Enderlein, 1922), bona species; 10 new combinations: Allotrichoma communis (Malloch, 1934), comb. nov., Athyroglossa bettelai (Canzoneri, 1995), comb. nov., Ceropsilopa africana (Canzoneri & Meneghini, 1969), comb. nov., Ceropsilopa flavescens (Frey, 1958), comb. nov., Diclasiopa affinis (Tonnoir & Malloch, 1926), comb. nov., Diclasiopa flavitarsis (Tonnoir & Malloch, 1926), comb. nov., Diclasiopa senegalensis (Canzoneri, 1981), comb. nov., Ditrichophora amoe…
isotracer: An R package for the analysis of tracer addition experiments
2022
Tracer addition experiments, particularly using isotopic tracers, are becoming increasingly important in a variety of studies aiming at characterizing the flows of molecules or nutrients at different levels of biological organization, from the cellular and tissue levels, to the organismal and ecosystem levels. However, performing rigorous statistical analyses to gain reliable quantitative insights from these experiments often remains challenging. We present an approach based on Hidden Markov Models (HMM) to estimate nutrient flow parameters across a network, and its implementation in the R package isotracer. The isotracer package is capable of handling a variety of tracer study designs, inc…
Cultivated mushrooms: importance of a multipurpose crop, with special focus on Italian fungiculture
2020
Fungi, organisms of high nutritional value with significant bioactive compound content, are considered to be nutraceuticals, mycotherapeutics, cosmeceuticals and useful for the production of functional foods. Their cultivation allows the sustainable management of agro-industrial wastes and generates good income with low inputs, constituting a good opportunity for the development of economically depressed rural areas. There are also many possible uses for the spent substrate in various sectors. provide an overview of the nutritional value of mushrooms and the cultivation of edible and medicinal mushrooms cultivation and uses in Italy.
Honeybees affect floral microbiome composition in a central food source for wild pollinators in boreal ecosystems
2021
AbstractBasic knowledge on dispersal of microbes in pollinator networks is essential for plant, insect, and microbial ecology. Thorough understanding of the ecological consequences of honeybee farming on these complex plant–pollinator–microbe interactions is a prerequisite for sustainable honeybee keeping. Most research on plant–pollinator–microbe interactions have focused on temperate agricultural systems. Therefore, information on a wild plant that is a seasonal bottleneck for pollinators in cold climate such as Salix phylicifolia is of specific importance. We investigated how floral visitation by insects influences the community structure of bacteria and fungi in Salix phylicifolia inflo…
Reliability of Frail and Barthel Tests for Detecting Frailty in Palliative Oncological Patients in a Home Hospitalization Unit: A Comparative Study.
2022
Cancer is a condition that can increase the risk of frailty. In addition, palliative oncological patients in home hospitalization can find their activities of daily living affected. The main objective was to measure the degree of frailty in the oncological population in home hospitalization comparing Barthel and Frail-VIG Indexes. This is a descriptive cross-sectional study. A sample of oncological patients in home hospitalization (n = 50) that included 27 men and 23 women were recruited, and disability due to frailty was measured using the VIG frailty index and the Barthel scale for Activities of Daily Living (ADLs). Spearman’s correlation coefficients were categorized as weak (rs &l…
