in this research the effects of crude oil on morphological and physiological characterization ofthe cyanobacterium microchaete tenera isc13 were investigated. isolated cyanobacterium treated with different oil concentrations (control, 1, 2.5, 5 and 7%) in carbonless bg110 medium. morphological characteristics such as morphology of filament, cellular shapes and sizes, relative position of hetero...

There have been acclaimed medicinal benefits of palm oil and kernel by rural dwellers in the southeastern part Nigeria. The study investigated phytochemical constituents antioxidant properties different varieties using standard methods. samples include: DPO (dura oil), TPO (tenera NDPKO native NTPKO (native tenera HDPKO hexane extract) HTPKO extract). Results obtained revealed presence steroids...

Invariant petal number is a characteristic of most flowers and is generally robust to genetic and environmental variation. We took advantage of the natural variation found in Cardamine hirsuta petal number to investigate the genetic basis of this trait in a case where robustness was lost during evolution. We used quantitative trait locus (QTL) analysis to characterize the genetic architecture o...

Understanding the factors that influence the distribution of understory vegetation is important for biological conservation and forest management. We compared understory species composition by multi-response permutation procedure and indicator species analysis between plots dominated by Qinghai spruce (Picea crassifolia Kom.) and Qilian juniper (Sabina przewalskii Kom.) in coniferous forests of...
