Environmental non-governmental organisations are opposed to this idea, therefore social tensions in the society are rising. The patterns of damage done to livestock were investigated by using data registered in the Biological Diversity Database (BDD) of the State Service for Protected Areas under the Ministry of Environment in the period from 1 January 2019 to 1 December 2021. Wolf diet was analysed by examining the stomach content of hunted wolves and the content of collected scats (n = 132). During the analysed period, 1139 cases of wolves attacking livestock were submitted to the BDD. Twenty-eight cases of wolves attacking dogs were submitted to BDD from 1 January 2019 to 1 December 2021. A total of 1167 animals were killed in 2019; 1279 animals were killed in 2020, and 875 animals were killed in 2021 (before 1 December). During the three years analysed, wolves most frequently attacked sheep (60.1–67.4% of cases annually). In accordance with the data gathered from analyses of the contents of wolves’ stomach and scats, remains of domestic animal were found in 6.82% of all samples.","PeriodicalId":8858,"journal":{"name":"Biologija","volume":"15 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91401665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Caused by differential precipitation, this seasonality induces seasonal variation in primary and secondary production. Birds are also affected. An avian community was studied in dry and wet seasons in an urbanised habitat of Tsumeb, a town situated in northern Namibia. Although both the species richness and the general dominance structure were similar in the dry and wet seasons, the avian community differed significantly in terms of population density of more common species in this town. Sörensen similarity index between the dry and wet seasons was low (I = 0.68). As expected, among granivorous species, the Laughing Dove (Streptopelia senegalensis), the Rosy-faced Parrot (Agapornis roseicollis), the House Sparrow (Passer domesticus), and the Southern Masked Weaver (Ploceus velatus) were much more numerous in the dry than in the wet season. However, contrary to expectation, the Blue Waxbill (Uraeginthus angolensis) was much more numerous in the wet than in the dry season. The Red-eyed Bulbul (Pycnonotus nigricans) was more common in the wet season, but other frugivorous species, the Red-faced Mousebird (Urocolius indicus), was more numerous in the dry than in the wet season.","PeriodicalId":8858,"journal":{"name":"Biologija","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73714662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main purpose of this study was to perform an analysis of genetic variability of Lithuanian cattle breeds. Three subpopulation groups were studied: Lithuanian Black and White (95 individuals), Lithuanian Red (49), and Lithuanian White and Red (48). Bovine genetic material was genotyped using a total of 11 fluorescent microsatellite primers to estimate genetic variability. All loci presented a high degree of polymorphism and a total of 292 different alleles (Na) were detected. Thirty-two private alleles were detected in all evaluated subpopulations. After completing pairwise population assignment, which is based on the distribution of allelic frequencies, three populations showed the tendency to group into three separate clusters. However, the performed Principal Coordinates Analysis (PCoA), which is based on genetic distances, showed no anticipated clear grouping. Bayesian structure analysis revealed three genetic clusters. Analysis of FST (0.001–0.027) and Nei genetic distance (0.029–0.084) revealed that the genetic diversity of inter subpopulation in cattle groups was estimated to be lower than the genetic diversity of intra subpopulation.","PeriodicalId":8858,"journal":{"name":"Biologija","volume":"67 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89842431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Very few morphometric measurements of European pond turtles are carried out in Lithuania. The purpose of this study was to perform morphometric measurements, assess migration, spread, and morphometric size variation. Morphometric measurements of juvenile European pond turtles showed that the morphometric indicators depended on the place of habitation: males from Juodabalė Zoological Reserve (Meteliai Regional Park) are smaller than females. Also, female turtles from Meteliai Regional Park are larger than both males and females from Kučiuliškė Herpetological Reserve. When comparing the morphometric indicators of males and females at ten months of age, sexual dimorphism is already observed: the shell height, the width of the head, carapace, and plastron of a females are already bigger than those of males.","PeriodicalId":8858,"journal":{"name":"Biologija","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87814988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

JAK2 small-molecule inhibitors have been proven to be clinically efficacious; however, they are not mutation-specific and competent enough to suppress neoplastic clonal haematopoiesis. There is a need for exploring new therapeutic strategies for MPN. Additional signaling systems, such as PI3K/Akt/mTOR and Hedgehog, are a potential treatment target. The aim of this study was to characterise and compare the effects of specific JAK/STAT, PI3K/Akt/mTOR, and Hedgehog signaling inhibitors in haematological cell cultures. JAK2 p.V617F mutated SET-2 and JAK2 wild-type UT-7 human cell lines were employed in our study. The effect of specific signaling pathway inhibitors was studied as time- and dose-response experiments. Viability was measured by trypan blue exclusion and alamarBlue assays. IC50 values were used to compare the effectiveness of inhibitors in decreasing cell viability. Independent sample t-test was used for statistical comparisons between experimental groups. p < 0.05 was considered significant. Our results indicate that all specific inhibitors progressively reduced the number of viable cells as the concentration and exposure duration increased. Inhibitors impaired the proliferation of JAK2 mutated cells at significantly lower doses compared to wild-type JAK2 cell line. These in vitro data indicate that JAK/STAT and alternative PI3K/Akt/mTOR and Hedgehog inhibitors have a potential anti-proliferative efficacy. Future studies, involving direct screening of PI3K/Akt/ mTOR, JAK/STAT, and Hedgehog signaling molecules activity, at gene and protein level in cell-based MPN model, are required.","PeriodicalId":8858,"journal":{"name":"Biologija","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78483338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
