In the last few years, interest in keeping city trees healthy has increased order to improve their survival and minimize claims due potential accidents. The pest diseases, pollution, climate change together with little genetic diversity of urban areas are some factors that contribute increase likelihood death and/or failure cities. This work is part a sanitary risk assessment plane street (Plat...

The amount of carbon fixed per plant (CFC per plant) and oxygen released per plant (ORC per plant) for Platanus acerifolia were 1080.72 and 785.98 g/d, respectively. The highest contents in carbon fixation and oxygen release of P. acerifolia may indicate a good photosynthetic capacity compared to S. japonica and Z. serrata. However, the later two species of trees were found efficient related to...

platanus acerifolia, london plane tree, a significant source of airborne allergens, is widely grown in shanghai and other cities in china. in recent decades, little has been known regarding the influence of the allergens on sensitizing the population in the shanghai area. the aims of this study were to purify and characterize the two major allergens and to confirm the immunological activities o...

Empregada na arborização urbana em muitas cidades, a árvore Platanus acerifolia Willd. (Platanaceae) está sujeita à ação de insetos fitófagos, dentre esses, o xilófago Pantophthaulmus pictus (Wiedemann, 1821) (Diptera: Pantophthalmidae), conhecido popularmente como mosca-da-madeira, que pela sua larva broqueia seu fuste. Portanto, este trabalho objetivou registrar e caracterizar os danos P. no ...

BACKGROUND There are no data on atmospheric pollen in Talca. In the present work, our aim is to describe the amount of pollen grain in the atmosphere of the city of Talca likely to cause pollinosis of its inhabitants. METHODS A volumetric Hirst sampler (Burkard seven-day recording device) was used to study pollen levels. It was placed in the centre of Talca from May 2007 to April 2008. RESU...

Throughout the Phanerozoic, estimated CO2 levels from proxies generally correlate well with independent estimates of temperature. However, some proxy atmospheric during Late Cretaceous and early Paleocene are low (<400 ppm), seemingly at odds elevated sea surface Here we evaluate by applying a leaf gas-exchange model to Platanites leaves four localities San Juan Basin, New Mexico (65.66–64.59 M...
