The search for new insecticides to control dengue fever, chikungunya, and Zika vectors has gained relevance in the past decades. The aim of the present study was to evaluate the larvicidal action of essential oils (EOs) from Thymus vulgaris, Salvia officinalis, Lippia origanoides, Eucalyptus globulus, Cymbopogon nardus, Cymbopogon martinii, Lippia alba, Pelargonium graveolens, Turnera diffusa, ...

The purpose of this investigation was to elucidate the anti-nociceptive and anti-inflammatory properties of aqueous acetone extracts from Cienfuegosia digitata Cav; and Sida Alba L. in Swiss mice, with an aim to provide a scientific basis for the traditional use of these plants in the treatment of inflammation disorders. In antiinflammatory activity, the carrageenan-induced paw edema and oil cr...

The composition and temporal variation in species recruitment were examined in relation to annual dendrochronological data to determine the historical development and successional history of an old-growth mixed-oak (Quercus) forest in northern Virginia, USA. A ridge site in the upland Piedmont, along the Potomac River, was used to survey the old-growth forest, which is dominated by Quercus alba...

The renewed interest in the use of hybrid zones for studying speciation calls for the identification and study of hybrid zones across a wide range of organisms, especially in long-lived taxa for which it is often difficult to generate interpopulation variation through controlled crosses. Here, we report on the extent and direction of introgression between two members of the "model tree" genus P...

Stem photosynthesis has been suggested to play relevant roles cope with different biotic and abiotic stress factors, including drought. In the present study, we performed measurements of stem hydraulic conductance non-structural carbohydrate content in evergreen Laurus nobilis L. deciduous Populusalba L., subjected inhibition successive exposure a drought-recovery cycle order check if may be in...

The aqueous and ethanol extracts of the leaves of Basella alba L. var. alba Wight, Basellaceae, were investigated for antiulcer activity on rats employing the pylorus ligation and ethanol induced ulcer models. The various gastric secretion parameters such as total acidity, free acidity, gastric acid volume, pH and histopathological parameters such as ulcer index and percent protection were comp...
