Understanding the ecological stoichiometry in the growth of different stand ages of Eucalyptus plantations is essential to evaluate the effects of management practices on biogeochemical cycling in plantation forest ecosystems. The study examined the relationship between leaf, litter, and soil stoichiometry on 3-, 6, 9-and 12-year-old Eucalyptus grandis x urophylla plantations in subtropical China. Results showed that (1) With increased stand age, the concentrations of TN (total nitrogen) and TP (total phosphorus) in leaf and litter increased gradually. Leaf TC (total carbon) concentration decreased gradually, litter TC concentration initially increased and then decreased, and the concentrations of TC and TN in soil were opposite. Soil TC and TN concentrations decreased with increasing soil depth. (2) The ratios of C:N, C:P, N:P were litter > leaf > soil. With increasing stand age, C:N and C:P of leaf and litter decreased gradually, while the ratios of C:N, C:P, N:P of soil fluctuated greatly. (3) There were significant negative correlations between the C, N of soil and litter P and significant positive correlation was between the leaf C:N and litter C:P. The main limiting element was P. The results of this study can provide a scientific basis for the management of Eucalyptus grandis x urophylla plantations.","PeriodicalId":7975,"journal":{"name":"Applied Ecology and Environmental Research","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67132628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the genetic diversity and structure of the rare and endangered relict plant Cycas shiwandashanica is the basis and prerequisite for formulating effective conservation and management strategies. In this study, the genetic diversity and genetic structure of 103 individuals from five populations of C. shiwandashanica were analyzed based on 6 pairs of SSR primers with good polymorphism and stable amplification. The results showed that at the population level, the Shannon information diversity index (I) was 0.709. The mean value of Ho was 0.453. The results indicated that C. shiwandashanica had high genetic diversity. There were significant differences among all populations. The total mean value of Wright fixed index F of the polymorphic loci of each population was -0.147, indicating that there was an excess of heterozygotes in each population. The analysis of molecular variance showed that 21% of the genetic variation existed in the population level and 79% in the individual level. The individual variation was the main source of the total variation of C. shiwandashanica . The results indicated that C. shiwandashanica had abundant genetic variation and high evolutionary potential. The maximum genetic distance between the five populations was 0.268423 (SY1/ZWS1) and the minimum was 0.049418 (SY1/MZT1). MZT1 and SY1 get together, then PFA1, and finally WWL1; This is consistent with the distribution location and distance of the wild population of C. shiwandashanica . Considering the current situation of the wild population of this species, it is suggested to establish a protection plot, carry out in situ protection, and strengthen the ex-situ protection measures such as introduction and artificial breeding. This study can provide theoretical support for the conservation of plant resources of C. shiwandashanica and has important theoretical and practical significance.","PeriodicalId":7975,"journal":{"name":"Applied Ecology and Environmental Research","volume":"21 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67132779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to recent genetic studies, there are eight subspecies of leopards (Panthera pardus) all over the world. Among these subspecies, the Anatolian leopard (Panthera pardus tulliana) is distributed in the southern and western regions of Turkey . It is a terrestrial mammal subspecies of Anatolia that is important historically, culturally and biologically. To date, there have been no studies about the Anatolian leopard, which is at the top of the food chain and has the characteristics of an umbrella species, key species and flag species in conservation studies. It is known that until 1975, the Anatolian leopard had dispersed along the forests of Central Anatolia, Mediterranean and Aegean regions. Since then, no living records have been taken, with the exception of unconfirmed information from scientists, local people and hunters. With this study, for the first time in history, one living individual(s) of the Anatolian leopard ( P. p. tulliana ) was photographed and video recorded via camera trap method, in the Western Taurus Mountains of the Mediterranean region of Turkey.","PeriodicalId":7975,"journal":{"name":"Applied Ecology and Environmental Research","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67126631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study was carried out in order to reveal the effects of exogen melatonin (50MT: 50 µM - 100 MT: 100 µM) treatment on the growth rate characteristic and bioactive compound content variations of three spinach cultivars (Acosta-ACO; Anlani-ANL, and Matador-MTR, respectively) grown under cold conditions. While MTR was the richest variety in terms of chlorophyll a, chlorophyll b, total chlorophyll, and carotenoid content, ANL was the richest variety in terms of Chl a to Chl b ratio, and xanthophyll content. Ascorbic acid and protein concentration were stimulated by MT in all three variants, but ANL had the highest value. While the proline content of cultivars decreased with only 50 MT in ACO when compared to the control, GB content decreased in MT doses. RWC increased with MT in ANL, whereas it caused to a decrease in RWC of 100 MT in ACO and 50 MT in MTR. MDA concentration was at a lower level and decreased only in ACO with 50 MT when compared to the control, while the H 2 O 2 concentration was higher at MT doses in all three species. MT treatment stimulated SOD activity in ACO and ANL and increased POD activity in all three variants. Considering the growth characteristics such as root/stem length, leaf characteristics, and biomass, exogenous MT doses had positive effects on all three cultivars. These findings suggest that foliar MT treatment can attenuate cold damage by enhancing the enzymatic and non-enzymatic antioxidant capacity of spinach seedlings, as well as the growth rate.","PeriodicalId":7975,"journal":{"name":"Applied Ecology and Environmental Research","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67126948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study we investigated the concentration of organochlorine pesticides (OCPs) in the gills and muscles as well as the levels of Thiobarbituric acid-reactive substances (TBARS), Catalase, GlutathioneS-Transferase (GST) and Acetylcholinesterase (AChE) activity in the liver and muscles of the bogue Boops boops (Linneaus,1758) fish that were caught in the bay of Oran (Algeria). For the purpose of evaluating the toxicological risk in the abovementioned area. The concentrations of total Dichlorodiphényltrichloroéthane (∑DDT) was present at highly significant levels (P˃0.001) compared to other OCPs, thus displayed in the following descending order: ∑DDTs > Lindane > Heptachlor. These OCPs had largely bioaccumulated in the gills compared to muscles. The PCA projection reported significant positive correlations between the concentrations of Lindane, DichloroDiphenyldichloroEthylene (DDE), DDD, DDT, and Heptachlor in gills and muscles. Seasonal variations of (OCPs) showed the highest average concentrations in the muscle and gills of fish collected mainly in Winter and Autumn (p < 0.001). The lowest concentrations were noted during the Spring and Summer periods. Significant negative correlations existed between the CAT, TBARS, GST and Lindane, ∑DDTs, and Heptachlor. The AChE (in liver and muscles) showed significant negative correlations with total DDT, with Correlation coefficient values R = - 0.67, R = - 0.64, respectively (significant R > 0.5). This study underlines that the bay of Oran suffers from chemical defilement.","PeriodicalId":7975,"journal":{"name":"Applied Ecology and Environmental Research","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67127694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the present work is the scientific evaluation of an Algerian endemic taxa ( Hypochaeris laevigata var . hipponensis Maire) widely used in folk medicine. For this objective, the active compounds, mineral element composition and antioxidant effects of three different extracts prepared from leaves were determined. Essays were started by a phytochemical screening, followed by mineral elements determination and leaf extract preparation using three organic solvents. The concentration of polyphenols, flavonoids, tannins, flavanols and orthodiphenols was determined in each extract as well as the radical scavenging activities and the total antioxidant properties. Correlation between bioactive compounds and antioxidant activities was also evaluated. Ethyl acetate extract showed the highest levels of polyphenols while the lowest one was found in raw extract, which contains the most important tannins. However, the lowest rate in anthocyanin was noted in butanol extract. Our data indicated that antioxidant properties varied according to extract type and radical scavenging used assay, indeed the half-maximal inhibitory concentration (IC 50 ) value ranged between 0.71 ± 0.02 and 7.00 ± 0.62 mg/g extract. Several positive correlations between secondary metabolite contents and antioxidant activities were registered. The obtained results support the influence of solvent extracts on bioactive compounds. These phytochemical constituents as well as mineral elements provide substantial antioxidant activities and explain the effectiveness of the studied species as traditional remedy.","PeriodicalId":7975,"journal":{"name":"Applied Ecology and Environmental Research","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67127901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
