The objectives of this research were to provide the first baseline survey of epibenthic communities in the Mekong estuaries and to describe more precisely the relationships between epibenthic characteristics and environmental parameters. In total, seven major taxa, including Bivalvia, Decapoda, Gastropoda, Isopoda, Molpadida, Stomatopoda, and Xiphosura were recorded in this estuarine system. The abundances of the epibenthic invertebrates range from 48 to 176 inds/1000 m2. Decapos always occupy the highest numbers with a percentage ranging from 86‒95%. There are 24 decapod species were recorded in this study with the following as dominant families Palaemonidae, Penaeidae, and Paguridae. Our findings highlight that the diversity of epibenthic communities, particularly for decapods, is notably high; however, the epibenthic density is considerably low. Epibenthic density and diversity were significantly correlated with salinity, TDS, depth, and pH but also other factors may play a role. The assessment of epibenthic assemblage diversity and its correlation with environmental factors holds significant importance in the formulation of conservation strategies.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":"24 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141609075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate the efficacy of different strains [Bti ATCC 35646 (wild-type strain), Bti pHT315, and Bti pHTppk (mutant strain)] of Diptera-targeted Bacillus thuringiensis subsp. israelensis (Bti) and toxins (spore/crystal mixtures) obtained from these strains against the 4th larval stage of T. wilkinsoni under laboratory conditions. T. wilkinsoni eggs were collected from pine trees at Ondokuz Mayıs University in Samsun, Turkey, in 2022. Pine needles were contaminated with bacterial strains of different concentrations (1 × 107, 1 × 108, 1 × 109 cfu/mL) in 5 mL and toxins in different concentrations (0.15, 0.3, 0.6, 1.25, 2.5, 5 mg/mL) in 2 mL. Larvae were placed in containers with 30 larvae in each group and were observed for 25 days. As a result of the study, Bti ATCC 35646 with 63.4% mortality and the lowest LC50 value of 1.2 × 109 cfu/mL among the three strains of Bti and Bti pHTppk with 76.7% mortality and the lowest LC50 value of 1.2 mL among the toxins from the Bti strains had found to be virulent for T. wilkinsoni. The results obtained from our study suggest that Diptera-targeted Bti is virulent to T. wilkinsoni and that this strain and spore/crystal mixture can be used in the biological control of this species.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":"70 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141609079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wild olives constitute a priceless reservoir of genetic diversity which has great value for olive breeding and conservation programs. However, global climate changes especially global warming is expected to threaten olive cultivation in future causing large economic loses in the region. Therefore, knowledge about distribution and abundance of wild olive populations is important to maximize their conservation, safeguard, and exploitation. Muğla province, where the wild olives make up an important part of the vegetation, is one of the main olive producing area in Turkey with many towns and villages dependent on the olive. In this study, our aim is to examine the current geographical distribution and density of wild olive populations in this province and the 82 islands around its coast. The results demonstrated that young olives, which show good adaptation to region, just have started to expand to the higher parts of the Kavaklıdere district. In addition, in most of the islands wild olives are preserved in their undisturbed natural habitats where they exist as small groves or scattered plants. The results of this study provides important insights for the conservation of wild olive genetic resources. The data reported here, are based on actual field data thus the geographic coverage tends to be complete and consistent.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":"4 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141609076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we studied the age structure, body size, and mass of an amphibian species (Pelophylax ridibundus) by sampling from two different frog farms in Türkiye. The age ranged from 4 to 13 (mean: 7.1) years in the Adana site while the age varied from 1 to 12 (mean: 5.2) years in the İstanbul site. Body size ranged between 88.21 and 103.72 mm (mean: 94.99 ± 1.15 mm) in the Adana site and 45.96 and 103.25 mm (mean: 75.90 ± 3.01 mm) in the İstanbul site. The t-test confirmed that the average age, SVL, and weight of the Adana site were higher than those of İstanbul. Body size markedly increased with age and weight (SVL-age: r = 0.659, p < 0.01; SVL-weight: r = 0.877, p < 0.001) in the İstanbul site, while in the Adana site, body size correlated only with weight.

We investigated the protective effects of phloretin against the PCOS, induced Bisphenol A (BPA) on prepubertal rat ovaries. This study started on female rats on the postnatal 28th day via subcutaneous injection by dissolving the compounds in corn oil at 30 min intervals, starting with phloretin, and followed by BPA. The dose of BPA was 50 mg/kg/day, and the doses of phloretin were 0.5, 5, and 50 mg/kg/day. Treatments were administered every day for 15 days. Likewise corn oil, BPA and testosterone propionate were given by the same way. BPA exposed groups, it has been observed that there are many cystic follicles in the ovary and their morphology has changed. Similarly, prolonged diestrus phases was observed in the smear cycle. The CYP11A1 and CYP17A enzymes stained intensively on the BPA group whereas these enzymes were stained weakly in the BPA + 5 and 50 mg/kg phloretin groups. In PCOS, induced by BPA, the cystic follicles were recorded on the ovaries whereas it was decreased in the BPA + phloretin groups. Prepubertal exposure to BPA was associated with decreased serum luteinizing hormone (LH), and follicle stimulating hormone (FSH) levels, increased estrogen (ERRα) and dihydrotestosterone (DHT) levels in testosterone propiyonat and BPA + phloretin (0.5 mg/kg/day) groups. In conclusion, in rat model, phloretin has positive effects against BPA induced polycystic ovarian syndrome, also it caused positive effects on ovarian tissue and hormone secretion.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":"2 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141195729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, we examined the antimicrobial potential of Cs-AgNPs and Fc-AgNPs against pathogenic bacterial strains, including Bacillus subtilis, Staphylococcus aureus, Enterococcus faecalis, and Escherichia coli, using the disc diffusion assay and minimum inhibitory concentration. Additionally, we evaluated the cytotoxic effects of Cs-AgNPs and Fc-AgNPs on various cell lines, namely breast adenocarcinoma (MCF-7), colon carcinoma (HT-29), human keratinocytes (HaCaT), and embryonic kidney (HEK-293), employing the Alamar Blue assay.

The presented study was conducted to explore the adverse effects of BPF on the adrenal glands of rats. Toward this aim, twenty-eight male albino Wistar rats were randomly divided into four groups, each containing seven individuals. The animals were administered a vehicle (control) or BPF at 3 different doses comprising 20, 100, and 500 mg/kg of body weight (bw) via oral gavage for 28 days. Next, the effects of BPF on the gland were evaluated in terms of histopathological alterations, serum adrenocorticotropic hormone (ACTH) and cortisol levels, and the contents of reduced glutathione (GSH) and malondialdehyde (MDA). The zona fasciculata of the adrenal cortex showed prominent histopathological lesions such as vacuolar degeneration and necrotic degeneration in the experimental groups. BPF caused noticeable elevations in the serum ACTH and cortisol levels. Moreover, decreases in levels of GSH and increments in the contents of MDA were determined, indicating oxidative stress. In conclusion, BPF showed toxic effects on the adrenal gland that may result in disruptions in its vital functions in the body. The results herein suggest that attention should be paid to the utilization of BPF in manufacturing processes due to its harmful effects and risks to the health of organisms.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":"31 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141255367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
