In this study efficacy of essential and fixed oil Laurus nobilis L., on controlling Aphis fabae Scopoli that grows Vicia faba L. (Fabaceae) has been studied by experiments set up in the laboratories Çukurova University Biology Plant Protection Departments 2016-2017. Fixed oils had previously found to be effective aphids according death rate Abbott test values, but they also phytotoxic effects p...

BACKGROUND Quorum sensing is the key regulator of virulence factors of Pseudomonas aeruginosa such as biofilm formation, motility, productions of proteases, hemolysin, pyocyanin, and toxins. The aim of this study was to explore the effect of the extracts from some medicinal plants on quorum sensing and related virulence factors of P. aeruginosa. MATERIAL AND METHODS Quorum sensing inhibitory ...

Correct identification of the true bay leaf (Laurus nobilis) and its substitutes is important not only for the quality control of the products, but also for the safety of the consumers. L. nobilis is often substituted or confused with other species, such as Cinnamomum tamala, Pimenta racemosa, Syzygium polyanthum, and Umbellularia californica. In the present study, the potential of gas chromato...

Vegetated marine habitats are globally important carbon sinks, making a significant contribution towards mitigating climate change, and they provide a wide range of other ecosystem services. However, large gaps in knowledge remain, particularly for seagrass meadows in Africa. The present study estimated biomass and sediment organic carbon (Corg) stocks of four dominant seagrass species in Gazi ...

We assessed the effects of hypoxia on macrobenthic communities in the York and Rappahannock Rivers, Chesapeake Bay, in box-core samples before and after hypoxic episodes in 2003 and 2004. Hypoxia occurred in both years and was associated with a decrease in biomass and a shift in community structure toward opportunistic species in both rivers. Long-term data indicate that the frequency of hypoxi...

An attack of Lauritrioza alacris (Flor, 1861) (Hemiptera: Triozidae) was recorded in a commercial plantation bay laurel (Laurus nobilis L., Lauraceae) the municipality Dois Lajeados, Rio Grande do Sul state (RS), Brazil. The immature triozids induced galls on attacked leaves consisting thickened margins that became folded downward, forming an elongated tube-shaped roll sheltered immatures. All ...

From mid-May to August 2011, extreme runoff in the Columbia River ranged from 14,000 to over 17,000 m(3)/s, more than two standard deviations above the mean for this period. The extreme runoff was the direct result of both melting of anomalously high snowpack and rainfall associated with the 2010-2011 La Niña. The effects of this increased freshwater discharge were observed off Newport, Oregon,...

The vertical distribution and abundance of conspicuous gastropod and bivalve species were studied at five rocky beaches in Cuastecomate Bay, Jalisco. Sampling was done from September, 1993 through March, 1994 with 0.75 m2 quadrants placed along replicate transect lines (10 m long) in the supralittoral and mesolittoral (upper, middle and lower intertidal) zones. A total of 6,643 mollusks were co...
