“…The phenological behavior of C. procera in the present study indicated that its vegetative phase continued throughout the year. This is in agreement with Parsons and Cuthbertson (2001) and Lottermoser (2011) who indicated that the growing season of this plant encompasses most of the year, as it is a perennial shrub. The continuous flowering and fruiting observed for C. procera in the present study for about 8 months during spring and summer coincides with that observed for the plant in many countries in the world (e.g., Singh and Yadava 1974;Eisikowitch, 1986;El-Ghani 1997;Sobrinho et al 2013).…”

“…It is native to tropical and subtropical Africa and Asia and common in the Middle East. This plant can tolerate adverse climatic conditions and poor soils (Parsons and Cuthbertson 2001;Lottermoser 2011). Recently, increased urbanization in Cairo, Egypt, has led to decrease in the biodiversity of many native plant species and exponential increase in others such as C. procera (El-Midany 2014).…”

Phenology is a major trait structuring life history strategies and its role in shaping plant invasions that has increasing attention. The present study aimed to examine the role of phenology, reproductive, and morphological attributes of Calotropis procera in colonizing urban areas, besides assessing its biomass and developing allometric regression equation for prediction of its biomass. Sixty-three permanent quadrats were selected to represent the distribution of C. procera in urban habitats at South Cairo Province, Egypt. The present study revealed significant positive correlation between fruiting phase of the species and temperature, as well as the vegetative phase and precipitation. C. procera is characterized by continuous flowering for 8 months, with a peak in April and May, which help in reproductive success of the species. It had its highest biomass in November (439 kg ha -1 ), but the lowest in March (343 kg ha -1 ), with an annual mean of 388 kg ha -1 . The linear regression based on plant volume as an independent variable was found to be the best fit for biomass prediction, with the highest coefficient of determination (R 2 = 0.81). The above-ground biomass of this plant encourages its potential use as a renewable energy source. Our study suggests that C. procera has efficient plastic phenological and functional attributes that may enable it to dominate many ecosystems in the future. Efficient management plans are needed to mitigate the risk of this plant on other ecosystems and conserve other native species.

A review is given regarding the medicinal plant Calotropis procera (Aiton) W.T a member of the family (Asclepiadaceae) commonly known as Giant Milk weed. It demonstrated that Calotropis is a perennial xerophytic woody shrub that has a great capacity to inhabit abandoned lands, it tolerated poor soils with limited nutrition and moisture, known to establish an intensive root system as a drought resistance mechanism. It exhibited allelopathic properties and phytoremediation, considered invasive in many habitats. C. procera is widespread in tropical and subtropical regions of the globe, in Egypt it's distributed through several phytogeographic regions with different edaphic properties, consequently, it showed great polymorphism and wide variety in metabolites in accordance to different environments. The seeds possess a unique silk formation that aided in dispersal through wind, water or any moving substance. Environmental conditions specially precipitation rates, was found to control the invasive behavior of the species since it showed no invasive attribute in arid environments where it's originally found such as Egypt or Saudi Arabia, on the contrary, Australia for instance knew C. procera as an invasive naturalized plant. A great benefit could be taken from Calotropis procera on many levels, as on one hand it is known traditionally, in folk medicine to have purgative and anthelimintic properties and used in treating leprosy, ulcers, tumors and piles as well as purgative, anticoagulant, and anticancer, moreover, the plant's latex has been known for cardiac glycoside content and contains compounds with pesticide properties, while on the other hand, its biomass proved a tendency to be a good source of renewable energy and hydrocarbon. Finally, Calotropis procera populations have an immense ecologic role being habitat for several organisms, displaying phytoremedy properties in contaminated soils and its ability to rehabilitate deserted land bringing back life once again.

“…The biogeochemical fate of uranium in polluted sites has been studied considering several aspects, such as the effect of microbial activity (e.g., Beazley et al, 2011;Hu et al, 2016), the plant-soil interaction (e.g., Tandy et al, 2013), the speciation, retention, mobility and bioavailability phenomena (e.g., Crawford and Liber, 2015;Du et al, 2016;Leermakers et al, 2016), the distribution in plants at the cellular level (e.g., Nie et al, 2015), the toxicity and biochemical responses in plants (e.g., Alves et al, 2009;Hogan et al, 2010;Horemans et al, 2016;Srivastava et al, 2010), the distribution in environmental compartments (e.g., Baumann et al, 2014;Kubrová et al, 2014;Pereira and Neves, 2012;Roivainen et al, 2011), the toxicity risk to biota, including humans (Caetano et al, 2014;Lottermoser, 2011;Pereira et al, 2014;Sheppard et al, 2005), and the prospects for U accumulation potential plant (e.g., Jha et al, 2016;Li et al, 2011;Pratas et al, 2014;Ramaswami et al, 2001).…”
