The results of analysis of soil and tree leaves samples collected from heavy traffic affected area of Agra city show that average concentration of Cu, Fe, Ni, Pb, Mn and Zn ranged from 0.953.42, 3.2811.26, 2.18-4.05, 3.04-8.10, 0.91-1.42 and 2.83-5.94 ppm , respectively in soil samples. The maximum concentration of Ni (2.68ppm) and Co (4.82 ppm) was observed in the leaves of Ficus religiosa and...

Background: Constructed wetlands are systems designed based on the utilization of natural processes, including vegetation, soil, and their associated microbial assemblage to assist in treating different types of wastewater. Methods: Two local Appalachian plants (Louis latifolia and Phragmites australis) were planted into smallscale constructed wetlands to treat domestic wastewater in the North ...

A new subgenus and new species, Nousia (Araucophlebia) latifolia subgen. et sp.n., are described from the Maule and Araucania regions in Chile, based on male and female imagos reared from larvae. This species has unusual shapes of larval tergalii, male imaginal genitalia and flat eggs.

Phytohemical investigation on the heartwood of Dalbergia odorifera resulted in the isolation of nine flavonoids. Their structures were elucidated as sativanone (1), (3R)-vestitone (2), (3R)-2',3',7-trihydroxy-4'-methoxyisoflavanone (3), (3R)-4'-methoxy-2',3,7-trihydroxyisoflavanone (4), carthamidin (5), liquiritigenin (6), isoliquiritigenin (7), (3R)-vestitol (8), and sulfuretin (9) based on th...

Introduction Dalbergia (Fabaceae) has a wide distribution, it is native to the tropical regions of Central and South America, Africa, Madagascar and southern Asia. Dalbergia odorifera T. Chen, a semi-deciduous arbor, is indigenous to Hainan, Guangdong and Guangxi Provinces of China. Its timber is high-grade material for furniture and crafts, and the essential oil of heartwood can be precious pe...

The role of nutrient availability in the decay of Typha latifolia and Cladium jamaicense litter and associated microbial responses were studied under controlled experimental conditions. The experimental setup consisted of three 14 m mesocosms: (i) an experimentally enriched (N&P) mesocosm containing organic soil, (ii) a mesocosm with organic soil but no external enrichment, and (iii) a mesocosm...

The major aim of the present study was to investigate element (Fe, Ni, Pb, V, Zn) concentrations in sediment and different tissues of Phragmities australis and Typha latifolia in Hor al-Azim Wetland Southwest Iran. Sampling of sediments and aquatic plants was carried out during spring and summer 2014. Results showed that the mean  concentrations of elements in Phragmities ...
