Keeping in mind limited data available on the taxonomic diversity of fishes from this region, we compiled time-series data on fish species from the PRE collected since the 1980s, and analyze diversity at different taxonomic levels using an inclusion index at the taxonomic level, and indexes of taxonomic diversity. Species inventory includes 18 orders, 79 families and 167 genera. Average numbers of (families, genera, species), (genera, species), and (species) per order, family, and genus, (4.39, 9.28, 14.94), (2.11, 3.41), and (1.61) were recorded. An average taxonomic distinctness of 75.0, and variation in taxonomic distinctness 99.8 were calculated. Whereas, an average taxonomic distinctness reveals genetic relationships between PRE fish species to be closer than in the East China Sea continental shelf (65.7) and Daya Bay (62.2), and more distant for the Dongsha Islands (55.2). Based on the overall results of the present study it is concluded that species abundance and taxonomic diversities in the PRE reflects healthy ecosystem of PRE.","PeriodicalId":19975,"journal":{"name":"Pakistan Journal of Zoology","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67573123","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}

A total of 250 chickens were sampled in three regions of the country of Tunisia. A complete description by direct observation, individual weighing, and body parts measurements were determined. The results of the study showed a significant diversity of plumage colors in the studied populations. Birds of the dominant yellow color represent the average proportion of 20 %. Birds with black, gray, and white plumage represent a low proportion (18%, 12%, and 12%, respectively). A great phenotypic diversity was noticed and the ascending hierarchical classification showed the existence of two different groups with differential body weight, body length, back length, comb length and width, ear lobe length and width, wing length, wattle length, neck length, thigh and breast length, shank length and diameter, and central toe length. This phenotypic and descriptive richness can be considered a starting point for categorizing local indigenous Tunisian chickens. Genetic, anatomic, and physiologic large-scale studies are warranted to establish a comprehensive database and improve the conservation and sustainable production of these indigenous chickens.","PeriodicalId":19975,"journal":{"name":"Pakistan Journal of Zoology","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67573428","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 P. stoliczkana mitochondrial genome contained a total of 16,966 base pairs, including 13 protein-coding genes, 22 transport RNA genes, two ribosomal RNA genes, and one control region. The A+T content (59.7%) of the whole mitochondrial genome was greater than the G+C content (40.3%), indicating an obvious A+T preference. The mitochondrial genome of P. stoliczkana is similar to that of most teleost fish, and no gene rearrangements were detected. The phylogenetic relationship tree of Smiliogastrinae fish was constructed based on 13 protein-coding genes using the Bayesian inference and maximum likelihood methods. We found that P. stoliczkana was closely related to Pethia ticto and Pethia padamya . These results enrich the mitochondrial genome database of Smiliogastrinae fish and provide reference materials for systematic classification of this group of fish.","PeriodicalId":19975,"journal":{"name":"Pakistan Journal of Zoology","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67575023","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}

{"title":"Effects of Different Quick-Freezing Methods and Storage Temperatures on the Content of Cryoprecipitated Blood Coagulation Factors in Fresh Plasma","authors":"Haiyan Wen","doi":"10.17582/journal.pjz/20230311210316","DOIUrl":"https://doi.org/10.17582/journal.pjz/20230311210316","url":null,"abstract":"To observe the effect of different quick-freezing methods and different storage temperatures on the content of cryoprecipitated blood coagulation factors in fresh plasma. The convenient sampling method was used to select 200 ml of whole blood from 60 unpaid blood donors who entered the blood station from January 2022 to October 2022. The acquisition time is controlled within 10 min. The plasma samples were divided into six groups (A, B, C, D, E, F) by using a random number table, 10 in each group. Group A (plate freezer for 30 min, - 30 ℃ storage), Group B (plate freezer for 30 min, 4 ℃ storage), Group C (plate freezer for 120 min, - 30 ℃ storage), Group D (plate freezer for 120 min, - 4 ℃ storage), Group E (plate freezer for 30 min, - 4 ℃ storage), Group F (plate freezer for 120 min, 4 ℃ storage). At 0, 3, 5, 7 and 9 h after the completion of the preparation of cryoprecipitate, the changes and differences of the content of coagulation factor VIII (Fv III) and fibrinogen (FIB) in the six groups of samples were observed. The highest level of FvIII occurred in group B at 5 h with a concentration of (2.47±0.56) IU/mL, while the lowest level occurred in group A at 9 h with a concentration of (0.84±0.07) IU/mL. The highest level of FIB occurred in group A at 0 h with a concentration of (245.56±25.92) mg/200ml, while the lowest level occurred in group C at 9 h with a concentration of (195.16±13.98) mg/200ml. It is preferable that both FvIII and FIB levels are at a higher level at 9 h, with group B having more appropriate levels of FvIII and FIB. According to the analysis of variance, the content of FvIII will be affected by the storage temperature, time, quick-freezing method, and the interaction between quick-freezing method and time (P<0.05). The content of FIB will be affected by the effects of quick-freezing method, time, quick-freezing method and storage temperature (P<0.05). Different quick-freezing methods and storage temperatures affect FvIII and FIB in the cryoprecipitated fresh plasma. The optimal quick-freezing method is the plate quick-freezing machine for 30min, and the storage temperature is 4 ℃ . Under this condition, the content of coagulation factor in the cryoprecipitate decreased more slowly.","PeriodicalId":19975,"journal":{"name":"Pakistan Journal of Zoology","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67575144","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}
