A new species of the genus Spiroxys (Nematoda: Gnathostomatidae) from Madagascan pleurodiran turtles (Pelomedusidae)
2008
AbstractSpiroxys ankarafantsika, sp. nov. is described from Madagascar in two species of freshwater turtles, Pelusios castanoides and Pelomedusa subrufa. Spiroxys ankarafantsika differs from other species of the genus in having pseudolabial teeth only on the median lobes and no other cuticular prominences, a smooth cuticular collar, deirides as cervical minute spine-like projections, and a gubernaculum without tubes. This is the first record of a nominal species of the genus Spiroxys from the Ethiopian region.
Gastrointestinal helminths found in the three freshwater turtles (Erymnochelys madagascariensis, Pelomedusa subrufa and Pelusios castanoides) from An…
2007
Abstract We conducted a survey of the presence, prevalence and diversity of gastrointestinal helminths in faecal samples and stomach contents of three turtle species, — Erymnochelys madagascariensis (Chelonia: Podocnemididae), Pelomedusa subrufa and Pelusios castanoides (Chelonia: Pelomedusidae), — from several localities in Madagascar. Four nematode species were detected: Atractis chabaudi, Camallanus chelonius, Falcaustra pelusios, and Spiroxys sp. E. madagascariensis, with all four species, had the greatest helminth diversity. A. chabaudi was the community’s core species, whereas Spiroxys sp. was a satellite species. Only two species (A. chabaudi and Spiroxys sp.) were found in P. subruf…
Mediterranean species of Eudendrium Ehrenberg, 1834 (Hydrozoa, Anthomedusae, Eudendriidae) with the description of a new species
2000
A new species of Eudendrium from the Chafarinas Islands (south-western Mediterranean) is described. The distinctive character of this species is its association with symbiotic zooxanthellae, a feature in common with Myrionema, the only other genus of the family Eudendriidae. The evolutionary implications of this similarity are discussed. A review of the Mediterranean species of Eudendriidae is presented, including data on the cnidome when available, biological data from the material studied, and a key to identify the Mediterranean species.
Saxifica Medusa (Luc. 9,670). Il ritratto della Gorgone
2016
Il contributo verte sul ritratto lucaneo di Medusa esaminato in rapporto al precedente ovidiano delle Metamorfosi e al profilo virgiliano di Alletto. La sinossi fra queste raffigurazioni è peraltro arricchita da un confronto ulteriore, la descrizione ovidiana di Tisifone contenuta nel IV libro delle Metamorfosi.In particolar modo vengono analizzati la descrizione del paesaggio dominato dalla Gorgone, speculare rispetto alla sua fisionomia orrida, e il volto del mostro, costruito con sagace Mosaiktechnik.
Rietumu medusbites (Apis mellifera L.) būtiskāko parazītisko mikrosporīdiju (Nosema spp.) un ērču (Varroa destructor) izplatību un sastopamību ietekm…
2019
Medusbišu, tāpat kā citu apputeksnētāju, skaita samazināšanās Eiropā un pasaulē kopumā saistāma t.sk. ar parazitārām slimībām. Šī pētījuma mērķis ir izpētīt Rietumu medusbišu (Apis mellifera L.) būtiskāko parazītu (Nosema spp., Varroa destructor) izplatību un sastopamību ietekmējošos faktorus Latvijā. Laikā no 2012.-2013. gadam ievākti bišu paraugi no 274 dravām, lai noteiktu to invāzijas slimību sastopamību Latvijas teritorijā. Pētījumā konstatēta Nosema spp. prevalence 49,5% un vidējā intensitāte 8,5x105 sporas uz vienu biti. Savukārt V. destructor prevalence bija 52,3% un vidējā intensitāte 3,0 ērces uz 100 bitēm. Būtiskākie parazītu sastopamību ietekmējošie faktori bitēs Latvijā bijā se…
Medus izcelsmes novērtēšana, izmantojot ķīmisko elementu un ogļhidrātu saturu
2022
Medus izcelsmes novērtēšana, izmantojot ķīmisko elementu un ogļhidrātu saturu. Bavrins K., zinātniskais vadītājs prof. Bartkevičs V. Maģistra darbs, 37 lappuses, 5 attēli, 15 tabulas, 44 literatūras avoti. Latviešu valodā. Medus ir uzskatīt par bioindikatoru vides piesārņojuma novērtēšanai. Nosakot tikai elementu un ogļhidrātu saturu medus paraugos, iespējams identificēt to izcelsmi un autentiskumu. Maģistra darba ietvaros apkopota informācija par medus elementu sastāvu un tā noteikšanas metodēm. Eksperimentālajā daļā noteikts elementu saturs medus paraugiem ar dažādu izcelsmi, kā arī ir veikta iegūto rezultātu statistiskā analīze, kas atklāja likumsakarības starp medus veidu un elementu un…

Forests as dispersal barriers for Erebia medusa (Nymphalidae, Lepidoptera)
2000
Summary The nymphalid butterfly Erebia medusa is a typical species of meadows that are poor in nitrogen and fallow land. In forests, it is only found on clearings with meadow-like structures. However, it is missing on wind exposed places, too. 239 imagoes of E. medusa were sampled in the Aggtelek Karst region (north-eastern Hungary) at six different localities at the end of May 1997. The sample sizes varied between 33 and 46. The studied karst area has a typical forest steppe vegetation and is characterised by a mosaic-like distribution of meadows and forests. The sampled butterflies were analysed by allozyme electrophoresis. The level of polymorphism was significantly higher in the samples…
Phylogenetic analysis of the Antarctic genus Oswaldella Stechow, 1919 (Hydrozoa, Leptomedusae, Kirchenpaueriidae)
1999
A cladistic study was carried out on known species of the characteristically Antarctic genus Oswaldella, adopting as out-groups some other genera included in the family Kirchenpaueriidae. The analysis resulted in a cladogram with low CI in which no relationship between genera can be depicted. However, the hypothesis of monophyly of the genus Oswaldella is corroborated, being supported in our cladogram by five synapomorphies (although all are homoplastic with other taxa or reversed within the species of the genus). The basal relationships of the genus are uncertain, but three species groups are distinguishable within Oswaldella: 1) the O. incognita group, 2) the O. Antarctica group, and 3) a…
