No full textThis article investigates tinned bronze ornaments found in two graves of the Lazdininkai-Kalnalaukis cemetery dated to the end of the 2nd century to the first quarter of the 3rd century AD from the perspective of archaeological materials, intercultural contacts, 14C AMS dating, and chemical-physical and biological research. These ornaments — a wheel-shaped pendant and a bead — were originally parts of fashionable necklaces. However, these ornaments went into the graves as spinning tools. The wheel-shaped pendant from grave 8(1992) contains the first ever found, or at least officially recorded, use in Lithuania of an aquatic plant for a spinning tool bobbin. The piece of possible linden tree wood was used to compose the spinning tool bobbin found in grave 68(2001). These spinning tools are the first to have appeared in Lithuanian archaeological material from as early as the end of the 2nd century to the first quarter of the 3rd century. In addition, both spinning tools are unique in the Lithuanian archaeological record so far in that the copper alloy spindle whorls were used to compose both working tools. The closest analogues for the wheel-shaped pendant are known from the Wielbark culture and this example should be considered as an import from that cultural area. Copper alloy beads and various local derivatives, however, are numerous in the range of the Baltic cultures area. The copper alloy wheel-shaped spindle whorls from the Migration period cemeteries are the spinning tools created for the specific purpose of spinning which were produced locally, even possibly in the same workshops
Veronica peregrina (Plantaginaceae), an alien species rediscovered in Lithuania /
No full textVeronica peregrina L. (Plantaginaceae) is a native species to North and South America and an alien to Europe. This species was first found in Lithuania in 1829, and no later records were made for almost two centuries. In May 2023, Veronica peregrina was rediscovered in Vilnius, Lithuania. Groups of plants and solitary individuals were scattered over ca. 1500 m². A total of about 700 individuals were found. Observed plants belong to the type subspecies Veronica peregrina L. subsp. peregrina. It is presumed that seeds of Veronica peregrina could have been introduced with plants from nurseries. The spread of this species in anthropogenic habitats in Lithuania is quite likely. Veronica peregrina is currently considered a casual alien in Lithuania
Novel insights into the genetics, morphology, distribution and hosts of the global fish parasitic digenean Proctoeces maculatus (Looss, 1901) (Digenea: Fellodistomidae) /
No full textLarval stages of the widely distributed digenean species Proctoeces maculatus (Looss, 1901) were reported 40 years ago from South Africa in the common octopus, Octopus vulgaris Cuvier (Octopodidae). However, the absence of adult specimens and molecular data from this region has hindered a comprehensive understanding of its distribution. In this study, we collected three species of intertidal and near-shore marine fishes [Clinus superciliosus (L.) (Clinidae), Diplodus capensis (Smith) (Sparidae), and Sparodon durbanensis (Castelnau) (Sparidae)] along the South African coast and discovered adult specimens of P. maculatus at five localities. By employing a combination of morphological and molecular techniques, including 28S rDNA, 18S rDNA, and COI mtDNA analysis, the first report of adult P. maculatus from South Africa is presented. The findings encompass a comprehensive morphological description and molecular data, illuminating the true distribution of this species in the region
Three new species of the genus Dolgoma Moore from Vietnam and China (Lepidoptera: Erebidae: Arctiinae: Lithosiini) /
No full textThree new species of the genus Dolgoma Moore, 1878 are described: Dolgoma nujianga sp. n. (China: Yunnan Province), Dolgoma lata sp. n. (Northern Vietnam), and Dolgoma brevivalva sp. n. (Northern Vietnam). A new combination is introduced: Dolgoma rubrescens (Hampson, 1909) comb. n. (endemic to Taiwan Island). Adults as well as male and female genitalia of the new and the similar species are illustrated
Environmental concentrations of Roundup in combination with chlorpromazine or heating causes biochemical disturbances in the bivalve mollusc Unio tumidus /
No full textBivalve molluscs represent the most recognized bioindicators of freshwater pollution. However, their ability to indicate specific xenobiotics in complex exposures is unclear. In this study, we aimed to track the particular effects of the pesticide Roundup (Rnd) and the antipsychotic drug chlorpromazine (Cpz) on the mussel Unio tumidus at the simpler environmentally relevant models. We treated the mussels by Rnd (17 μg L−1), Cpz (18 μg L−1), the mixture of Rnd and Cpz at 18 °C (RndCpz), and Rnd at 25 °C (RndT) and examined their digestive glands after 14 days of exposure. We analyzed total antioxidant capacity, glutathione (GSH&GSSG) and protein carbonyls levels, total and Zn-related concentrations of metallothioneins (MT and Zn-MT, respectively), the activities of CYP450-related EROD, glutathione S-transferase, cholinesterase, caspase-3, citrate synthase (CS), lysosomal membrane integrity (NRR), and Zn level in the tissue. Shared responses were indicated as the increase of the antioxidant, Zn-MT, and EROD levels, whereas the changes of Zn concentration, NRR, and caspase-3 activity were most diverse compared to control. According to discriminant analysis, complex exposures abolished the individual response traits and intensified the harmful effects that caused a decrease in the Zn level in the RndCpz- and RndT-groups and the loss of lysosomal integrity in the RndT-group. We concluded that multi-marker expertise with the application of integrated indices had benefits when evaluating the effects of complex exposures.
