Seasonal radial increment, tree water deficit (ΔW) and maximum daily shrinkage (MDS) were derived from the records obtained using high-resolution digital band dendrometers. The study area was located in Arboretum Borová hora (350 m a. s. l., Zvolen valley, Central Slovakia) characterised by a warmer climate (<i>Picea abies</i>) and warmer and drier climate (<i>Abies alba</i>, <i>Larix decidua</i>, <i>Pinus sylvestris</i>) compared to the sites of tree origins. Monitored species exhibited remarkably distinct growth and water balance patterns over the 2015 growing season characterised with the highly above normal temperature and uneven precipitation distribution. <i>A. alba</i> exhibited smooth continuous growth least affected by varying environmental conditions. Of all analysed species, only <i>A. alba</i> showed significant positive correlations of radial growth and ΔW with temperature and global radiation, despite environmental water limitations. The lowest cumulative growth, lower negative values of ΔW and greater MDS of <i>L. decidua</i> indicate a higher water limitation of this species. The results showed more pronounced sensitivity of <i>P. sylvestris</i> to increased temperature and drought. All monitored variables of environmental conditions, except precipitation, significantly influenced MDS values of all studied tree species. Based on 30 variables describing radial stem growth patterns and water status we identified large inter-species variability and discrete species-specific groups, while the indicators of growth and water status of <i>L. decidua</i> and <i>P. sylvestris</i> were similar and the most different patterns were observed between <i>A. alba</i> and <i>L. decidua</i>. The behaviour of <i>P. abies</i> was closer to <i>A. alba</i> than to the other two species.</p>","PeriodicalId":8978,"journal":{"name":"Biologia","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140882248","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}

Knowledge about mosquito ecology in southern Indiana is limited. Here, we present results from a season long study where we sampled mosquitoes at the Hickory Ridge Fire Tower in Hoosier National Forest, Monroe County, Indiana, USA. Using BG-Pro traps with BG-Lure and LED lights weekly from 23 May to 31 October 2023, we collected 178 mosquitoes over 24 weeks of sampling, encompassing a total of 120 trap-nights, with an average of 1.48 ± 3.41 (SD) mosquitoes per trap-night. The species accumulation curve for all the samples was flat, indicating a comprehensive sampling of species. We collected 10 species with a Chao2 ± SE species richness estimate of 14.46 ± 7.14. The dominant species was <i>Aedes vexans</i> (<i>n</i> = 58, 36%), followed by <i>Culex</i> spp. (composed of morphologically indistinguishable <i>Culex pipiens</i> and <i>Culex restuans</i>) (<i>n</i> = 51, 31%), <i>Culex erraticus</i> (<i>n</i> = 16, 10%), and <i>Aedes triseriatus</i> (<i>n</i> = 15, 9%). Because mosquitoes are ectothermic, they are highly sensitive to microclimatic variables such as temperature, humidity, and rainfall. Our time series analysis showed a significant association of mosquito abundance with the variability (SD and kurtosis) of the environmental variables we studied highlighting the importance of weather fluctuations in mosquito ecology. Our study highlights how weather variability shapes mosquito abundance, thus impacting disease vectors like <i>Culex</i> spp. and <i>Aedes triseriatus</i> with implications for arbovirus transmission in the context of climate change.</p>","PeriodicalId":8978,"journal":{"name":"Biologia","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140882228","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}

Field data were obtained through nightly monitoring during the breeding seasons from 2018 to 2020. Although lunar luminosity and lunar phases did not exhibit a statistically significant effect, the highest number of nesting occurrences was observed during the full moon and new moon, which may be related to the spring tide. The SST was the only variable showing a statistically significant relationship with complete oviposition, incomplete oviposition, and false crawl occurrences, indicating the preference of turtles to come ashore at higher temperatures (around 29.5 °C). Furthermore, while lunar luminosity and lunar phases may have some influence on the nesting pattern of the green turtle, they do not limit it, as turtles come ashore under different observed environmental conditions.\u0000</p>","PeriodicalId":8978,"journal":{"name":"Biologia","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140831034","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}

The present study investigated the physiological and molecular responses of basil seedlings (<i>Ocimum basilicum</i>) subjected to AgNPs or silver nitrate (AgNO₃) for 7 days. The seedlings were treated with 0, 4, 10, or 40 mg/L of AgNO₃ or AgNPs in Hoagland’s solution. Both treatments resulted in significant accumulation of Ag in the roots and shoots, with higher levels in the roots of AgNO₃-treated seedlings. AgNPs increased plant biomass at 4 mg/L, while AgNO₃ decreased it at all concentrations. Both treatments reduced the total chlorophyll, carotenoids, and carbohydrates, with more pronounced effects in AgNO₃-treated seedlings. Both treatments also induced oxidative stress, as indicated by increased levels of H₂O₂, malondialdehyde (MDA), and proline, and enhanced activity of antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX). However, these responses were more evident in AgNO₃-treated seedlings, especially at higher concentrations. Quantitative real-time PCR analysis revealed that both treatments induced the upregulation of genes encoding oxidative stress tolerance-related enzymes, such as FSD1, MSD1, CSD1, CATa, CATb, APXa and APXb, in the basil seedling shoots. These results suggest that AgNPs are less toxic to basil plants than AgNO₃ and that basil plants can activate physiological and molecular mechanisms to cope with Ag-induced oxidative stress.</p>","PeriodicalId":8978,"journal":{"name":"Biologia","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140831071","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}
