Abstract:

ABSTRACT Micromonospora species live in diverse environments and exhibit a broad range of functions, including antibiotic production, biocontrol, and degradation of complex polysaccharides. To learn more about these versatile actinomycetes, we sequenced the genome of strain L5, originally isolated from root nodules of an actinorhizal plant growing in Mexico.

Nutrient Requirements of Some Casuarina equisetifolia Plantations in Maharashtra and Gujarat

Indian Forester (1967)

The study formed a part of similar work undertaken on the species in other coastal areas where Casuarina is grown. Since in some areas mortality of Cosuarina equisetifolia was reported, it was considered necessary to know the nutrient requirements of the species coupled with soil studies, in order to find out whether the sites where the species is grown meet the requirements. Nutrient requirements of Casuarina equisetifnlia were studied by means of foliar analysis. The results indicate that there is rise in the uptake of N, K and Mg in 4 snd 5 year old crops after which there is not much variation. While Ca uptake does not show any regular trends P uptake is lower in higher age group crops. Since most of the areas where Casuarina is grown have sandy soil, it is suggested that the fertilizer application of all the minerals Except P, to 3-4 years old plantations in the form of a balanced dose may probably result in better growth in area.Where growth is found to be not up to the mark.

Soil Property Differences Between Invaded Casuarina (Casuarina equisetifolia L.) Sites and Non-Casuarina Sites in the Bahamas

Physical Geography (2012)

Charlotte Buehler John Rodgers

Casuarina (Casuarina equisetifolia) is a problematic invasive species within the Bahamas, associated with numerous environmental problems. Previous studies suggest casuarinas establish ecologically sterile monocultures, yet there is limited research on whether soils from casuarina-dominated sites differ physically or chemically from comparable soils under native vegetation. Because of the lack of knowledge and because this invader has the potential to be detrimental to native ecosystems, we conducted a study to examine differences in soil properties between sites where casuarinas dominated versus sites where casuarinas were absent. Soils at casuarina-dominated sites had lower potassium, phosphorus, and organic matter concentrations and had lower pH levels. But, casuarina-dominated sites had significantly higher leaf-litter abundances. No significant differences between soils were detected for calcium concentrations, magnesium concentrations, cation exchange capacity, nitrate-nitrogen concentrations, or soil moisture levels. A multivariate ordination showed that casuarina-dominated soils were more similar to one another than to non-casuarina soils. Thus, soil characteristics from casuarina-dominated areas appear to differ from comparable habitats devoid of casuarinas. There are at least two possible explanations: certain soil properties may have been more conducive to casuarina invasions, or casuarinas may have modified their soils once they became established. The results of this study provide insights into the invasion process and add to our understanding of how these invaders affect native Bahamian ecosystems.
