In the current study, the spring migration of soaring birds was studied along a narrow corridor “bottleneck site” located within the Red Sea/Rift Valley bird migration flyway, Gulf of Suez, Egypt. Over a period of four weeks from April 19th to 17th of May 2019, 89949 soaring birds of 27 species were counted during an eight-hour daily observation window. In total, 47511 raptors of 24 species were recorded. The most common were the group of Levant sparrowhawk “Accipter brevipes”, European honey buzzard “Pernis apivorus”, and Northern steppe buzzard “Buteo buteo vulpinus” forming 33.16%, 32.08%, and 24.91% of all raptors, respectively; while combined black kite “Milvus migrans”, lesser spotted eagle “Aquila pomarine”, steppe eagle “Aquila nipalensis”, short-toed eagle “Circaetus gallicus”, booted eagle “Aquila pennata”, and Egyptian vulture “Neophron percnopterus” recorded more than 6% of the raptor assemblage. In addition, 15 greater spotted eagle “Aquila clanga”, 6 pallid harrier “Circus macrourus”, and 5 Eurasian griffon vulture “Gyps fulvus” were recorded during the observations. Other soaring birds were recorded during the study-time, the most common were: 36700 white stork “Ciconia Ciconia”, 4230 great white pelican “Pelecanus onocrotalus”, and 1500 black stork “Ciconia nigra”.","PeriodicalId":11659,"journal":{"name":"Egyptian Journal of Zoology","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79220277","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}

These species were Lethrinus lentjan, L. harak, L. microdon, and L. mahsena. DNA was extracted from these samples and subjected to polymerase chain reaction (PCR) amplification for the mitochondrial 12S ribosomal RNA (rRNA) and the nuclear 5S rRNA genes. The 12S rRNA PCR amplicons were sequenced. GenBank comparison and phylogenetic analysis for the 12S rRNA gene sequences resulted in clear identification for the sampled species. Meanwhile, a simple, 2% agarose gel electrophoresis for the 5S rDNA ran in a low voltage for 2 hours resulted in variable intraspecific patterns. These patterns appeared as 3 PCR bands of approximately 500 base pair (bp) in length for L. lentjan; 2 PCR bands at 500 and 400 bp for L. harak; single PCR band at 500 bp for L. microdon; and 3 bands at about 750, 500, and 400 bp for L. mahsena.

Therefore, they have powerful antimicrobial agents. The present study was designed to evaluate the antibacterial efficiency of different extracts of terrestrial gastropods against two pathogenic bacteria: Escherichia coli and Staphylococcus aureus. Phosphate buffer saline (PBS), acetone, and methanol were used to extract viscera, haemolymph, and mucus from the snails, Helix aspersa and Eobania vermiculata, and the slug, Deroceras reticulatum. All extracts from haemolymph and mucus of the three snails did not inhibit the growth of the selected pathogenic bacteria. However, the methanolic extract of E. vermiculata viscera inhibited the growth of S. aureus at 50% concentration; and the inhibition zone reached 12.3 ± 0.6 mm. In addition, the methanolic extract of H. aspersa viscera inhibited the growth of S. aureus at 100 and 50% concentrations up to 19.3 ± 0.6 and 18.0 ± 0.1 mm, respectively, and induced a moderate decrease in the growth of E. coli at 100% concentration. In addition, scanning electron microscopy (SEM) assured damaging impacts of the methanolic and PBS viscera extracts of the two snails “H. aspersa and E. vermiculata” on both E. coli and S. aureus. In conclusion, the antibacterial properties of the methanolic viscera extracts of the terrestrial gastropods may encourage the discovery of new and safe antibiotics from animal origin.","PeriodicalId":11659,"journal":{"name":"Egyptian Journal of Zoology","volume":"120 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76407714","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}

Most freshwater bodies support different mosquito species breeding. The physicochemical characteristics of mosquito breeding sites may influence culicine species distribution and their abundance. This study aimed to determine culicine species communities and their abundance in two rural sites and one urban breeding site in Egypt considering physicochemical characteristics of breeding places. These areas were Al-Beshlawy drainage canal (Giza), El-Khartoum irrigation ditch (Beheira), and Tanta man-made ground hole (Gharbia), respectively. The measured physicochemical parameters were temperature, pH, salinity, turbidity, dissolved oxygen, and nitrite. Diversity indices (recorded number of species, diversity, equitability, and concentration of dominance) of mosquitoes were also calculated. The results showed that six culicine species were identified in the tested three breeding sites. These were Culex pipiens, Cx. univittatus, Cx. antennatus, Cx. quinqueifasciatus, Cx. perexiguus, and Culiseta longiareolata. All species are native to the Egyptian fauna. In all tested urban and rural breeding sites, Cx. pipiens was considered eudominant. Bray-Curtis dissimilarity in the culicine community between the tested sites ranged between 0.03 and 0.12. This dissimilarity may be attributed to the absence of certain species in some sites, as well as the significant difference in the abundance of Cx. pipiens and Cs. longiareolata among the sites. Water salinity and dissolved nitrite content differed significantly among the breeding sites. The multiple regression analysis between the identified culicine species and the physicochemical parameters showed that salinity, nitrite content, turbidity, and pH are considered key factors to predict some culicine species in water bodies.","PeriodicalId":11659,"journal":{"name":"Egyptian Journal of Zoology","volume":"99 1","pages":"30-42"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80569783","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 current study investigated the potential hepatoprotective benefits of propolis in CCl4-treated mice. Three groups of male BALB/c mice (n=15/group) were used in the current study: group I comprised the control mice, groups II was intraperitoneally injected with CCl4 (1.0 mL of 10% CCl4dissolved in olive oil/kg body weight, twice/week for six weeks) for inducing liver fibrosis, group III was treated with CCl4 as in group II and then supplemented orally with the ethanol-soluble derivative of propolis (100 mg/kg body weight/day) for additional four weeks. The antifibrotic effects of propolis were assessed by histological analysis, Western blotting, flow cytometry, and ELISA. The results indicated that the CCl4-treated mice exhibited histopathological alterations in the liver architecture with an increase in the numbers of Kupffer cells, a significant increase in the lymphocytes apoptosis and in the plasma nitric oxide, reactive oxygen species, C-reactive protein, and platelet derived growth factor levels, and a significant decrease in the plasma total glutathione level, as compared with the control group. The liver of CCl4-treated mice also exhibited a significant increase in the expression of collagen and survivin, upregulation of signal transducer and activator of transcription 3 (STAT3) phosphorylation, and downregulation of STAT5 phosphorylation. Interestingly, propolis abrogated significantly the hepatic collagen deposition, inflammatory signals, and oxidative stress, and improved the hepatic architecture in CCl4-treated mice nearly to the normal architecture observed in the control mice. In conclusion, our findings demonstrate the potential hepatoprotective effects of propolis in alleviating the liver fibrosis.","PeriodicalId":11659,"journal":{"name":"Egyptian Journal of Zoology","volume":"70 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83751937","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}

Plant essential oils play a promising role in integrated pest-management programs. In the present study, the insecticidal activities of six essential oils from clove (Syzygium aromaticum), crane’s-bills (Geranium sp.), citronella (Cymbopogon sp.), dill (Anethum graveolens), cinnamon (Cinnamomum camphora) and basil (Ocimum basilicum) were investigated against the cotton leafworm, Spodoptera littoralis “Boisduval” (Lepidoptera: Noctuidae). The toxicity test revealed that all the tested essential oils have noticeable insecticidal activity. The basil oil was the most efficient against the 3rd instar larvae, with the lethal concentration (LC)50=0.42%; while the dill oil showed higher toxicity than the other oils against the 5th instar larvae (LC50=0.49%) after 48 hours of treatment. The impact of the tested essential oils on the acetylcholinesterase (AChE), carboxylesterase (CE), and glutathione S-transferase (GST) activities was also assessed. The basil oil induced the activity of AChE in both the 3rd and the 5th instar larvae. All tested oils elevated GST activity in the 5th instar larvae, except citronella oil. The dill oil decreased CE activity in both instars. Genotoxicity analysis using comet assay revealed that all assay parameters differed significantly, compared to the control. The maximum percentage of damaged DNA was detected in larvae treated with basil followed by dill, cinnamon, clove, citronella and crane's-bills, respectively. It was concluded that these essential oils could play a promising role in controlling S. littoralis and providing a biological alternative to synthetic insecticides in the control programs.","PeriodicalId":11659,"journal":{"name":"Egyptian Journal of Zoology","volume":"61 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90727847","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}
