New Data on the Ecology of the Fossil Don Hare Lepus tanaiticus Gureev, 1964
Dokl Biol Sci. 2024 Mar 2. doi: 10.1134/S0012496624700923. Online ahead of print.ABSTRACTA spore and pollen research was performed for the first time to study the contents of the gastrointestinal tracts (GITs) and sediments containing frozen mummies of the fossil Don hare from the Upper Pleistocene ice complex of the Verkhoyansk district of Yakutia. Radiocarbon dating (C14) revealed that the hares lived during the Karginian Interstadial of the Late Pleistocene, 32.5 thousand years ago (calibrated date). The results expanded the understanding of the ecology of extinct Lepus tanaiticus. The species was assumed to live in col...

Are Abnormally Large Eastern Bent-Wing Bats, Miniopterus fuliginosus, the Result of a Feature Shift or the Result of Hybridization?
Dokl Biol Sci. 2024 Mar 2. doi: 10.1134/S0012496624700911. Online ahead of print.ABSTRACTDuring a study of morphological variations in bent-wing bats (Miniopterus), we found that specimens originating from the Cao Bang province of Vietnam, identified as M. fuliginosus, were closer in size to the larger species, M. magnater. Mitochondrial gene analysis clearly places these specimens in the former species. At the same time, morphometric analysis of 21 cranial measurements definitely puts these specimens closer to M. magnater and shows their differences from M. fuliginosus samples from different parts of the species range. We...

Seed Treatment with Salicylic Acid Increases Gene Expression and Activity of Antioxidant Enzymes in Wheat Plants in Zinc or Copper Deficiency
Dokl Biol Sci. 2024 Mar 2. doi: 10.1134/S001249662470090X. Online ahead of print.ABSTRACTThe effect of wheat seed treatment with salicylic acid (SA) on expression of the TaCu/ZnSOD, TaFeSOD, and TaCAT2 genes and activities of the antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT) in leaves was studied at optimal contents of zinc (2 µM) and copper (0.3 µM) in the root environment and in zinc and copper deficiencies. Seed treatment with SA was for the first time shown to increase of the amount of transcripts of the above genes as compared with untreated plants, both in optimal conditions and in zinc or coppe...

Functional Activity of the Blood System in Two Migratory Bat Species of the Urals
Dokl Biol Sci. 2024 Mar 2. doi: 10.1134/S0012496623700898. Online ahead of print.ABSTRACTFunctional activity of the blood system was studied in two migratory Ural species, Vespertilio murinus Linnaeus, 1758 and Pipistrellus nathusii Keyserling et Blasius, 1839. A multivariate nonparametric ANOVA of red blood parameters showed significant interspecific differences (p < 0.05) between the migrating bats and the resident species pond bat. A certain genetically determined multidirectionality in the mobilization of emergency regulation mechanisms of the lymphoid blood system was observed in bats.PMID:38430296 | DOI:10.1134/S0...

Identification of Ultrastructural Details of the Astrocyte Process System in Nervous Tissue of the Brain Using Correlative Scanning Probe and Transmission Electron Microscopy
Dokl Biol Sci. 2024 Mar 2. doi: 10.1134/S0012496623600185. Online ahead of print.ABSTRACTNanoscale morphological features of branched processes of glial cells may be of decisive importance for neuron-astrocyte interactions in health and disease. The paper presents the results of a correlation analysis of images of thin processes of astrocytes in nervous tissue of the mouse brain, which were obtained by scanning probe microscopy (SPM) and transmission electron microscopy (TEM) with high spatial resolution. Samples were prepared and imaged using a unique hardware combination of ultramicrotomy and SPM. Astrocyte details with ...
