The monogynous hawthorn or Crataegus monogyna Jacq (Rosaceae) is a medicinal plant used since antiquity in traditional medicine, recognized by its therapeutic virtues. This study aims to estimate the total phenols and flavonoids contents and to evaluate the antioxidant and antibacterial activity in vitro from the methanolic extract of the C. monogyna leaves. Antioxidant activity was investigated with six methods, DPPH, ABTS, galvinoxyl scavenging activities. FRAP, CUPRAC and phenanthroline assays , Total phenols and flavonoids contents were studied by Folin–Ciocalteau and aluminum colorimetric methods. The antibacterial activity of the methanolic extract was evaluated against Staphylococcus aureus , Proteus mirabilis , Pseudomonas aeruginosa , Escherichia coli and Streptococcus Sp in the base of inhibition zone diameter using agar diffusion method . The findings showed a significant antioxidant activity by the methods of DPPH (IC 50 =28.00±0.97 μ g/ml), CUPRAC (A 0.5 =28.79± 2.10µg/ml), ABTS (IC 50 =10.12±0.60µg/ml), phenanthroline (A 0.5 =36.84±1.85µg/ml), GOR (IC 50 = 20.76±0.40 μ g/ml) but this activity is absent with FRAP assay. The amount of TPC was very high in this extract (201.47±0.55 µg EAG/mg), while the value of flavonoids was moderate (75.48 ±5.77µg EQ/mg). The methanolic extract of C. monogyna leaves showed a significant antibacterial potency. The present study has demonstrated that C. monogyna extract possess potent antioxidant capacity and a good antibacterial activity, which could be include in medicinal use.

The finding of two further non indigenous species for the Eastern Sicilian rocky coast is here reported. The neo-gastropods Aplus assimilis (Reeve, 1846) and Mitrella psilla (Duclos, 1846) were found living inside the arbor of Catania. Specimens regularly collected during these last five years demonstrate the stability of the populations of both the species inside the harbor, while no other materials emerged from the exam of samples collected around the finding lo-cality. The presence of both the species along Italian coasts was previously ascertained in few scattered localities, while the current represents the first report for Sicily. A human-mediated diffusion is here supposed as for other species found in the island. This last finding brings back to the top the problem of the numerous alien species arrivals during these latest years in Sicily and, more generally, in the Mediterranean Sea.

Through the present study, new data on the biology and ecology of dorids along the central-eastern coast of Sicily (Italy), whose knowledge was previously scant and fragmentary, have been here provided. After a brief description of this group of nudibranchs, for each species data on morphology, abundance, location and depth, substrates and habitats, seasonality and remarks are here given. Moreover, through this study, two species, Crimora papillata Alder et Hancock, 1862 and Geitodoris portmanni (Schmekel, 1972) are reported for the first time for the central-eastern coast of Sicily. This study highlighted that along this area there is almost the 28% of the total Mediterranean dorid fauna. Consequently, only through a continuous monitoring, it is possible to achieve a good knowledge of any group of marine heterobranchs in a given area.

Mercury toxicity is believed to be a widespread environmental dilemma that has been creating tremendous damages not only to humans, but also to wildlife. Owing to its sensitivity to mercury toxicity, F. cancrivora was subjected for the determination of total mercury (THg). The food intake of frogs is claimed to influence mercury concentration on its body, thus its stomach content was also subjected for analysis. The analysis on the gut contents of F. cancrivora revealed ten (10) food items in which the insect parts got the highest percentage of occurrence (74.19%). In addition, the total mercury concentration found on the gut of F. cancrivora is below the detection limit of <0.02 ug/g which passed USEPA standard of 0.50 ug/g implying that the detected mercury level is still acceptable. This study would like to recommend control and prevention of mercury contamination in the mining area. ABSTRACT
