Assessment of phytoremediation potential of Telfaira occidentalis in the removal of Cu, Cd, and Pb in contaminated soil along River Salanta

A Field study was carried out to examine the phytoremediation potential of some plants metals (Cd, Cu and Pb) in contaminated soils along Sallanta river, Kano. A total of one hundred and eighty (100) samples comprising of 40 (soils), 20 (effluents), and 40 (plant parts) of T. 0ccidentalis were analyzed. 0.50g of the plant tissue and 1.0g of soil sample and 50mL of the effluent sample were digested using triacid digestion method and the levels of the metals were determined by the use of atomic absorption spectrophotometry. The mean levels of the metals in plants and soils from contaminated and control sites were found to be in the sequence of Cu (27.08±3.15)> Cd (24.57±8.25)>Pb (3.00±0.52) and Cu (10.10±2.50)> Cd (2.80±0.05)>Pb (2.00±0.63) respectively. The contamination factor (CF) of all the metals in the plants were found to be in the sequence of Cd (8.35±1.53)> Cu (2.52±1.20)>Pb (1.50±0.21). The results showed that these plants can be used for the phytoextraction of the metals from contaminated soils. The values of bioaccumulation and translocation factors were also found to be more than one in almost all cases. From these results it could be recommended that the three plants investigated would be ideal for phytoremediation in multi-metal contaminated soils

Amphibian Fauna of Manipur, North East India

Manipur is one of the eight states of North-Eastern India, situated at the confluence and conjunction of two biodiversity hotspots- the Himalayan and Indo- Burma hot spots. It lies between 23°80′ N to 25°70′ N latitudes and 93°50′ E to 94°80′ E longitude, bounded by Nagaland in the North, Assam in the East, Mizoram in the south, and Myanmar in the east and southeast. Manipur has a rich diversity of culture and tradition also. The state has varied physiographic zones harboring rich and diversified amphibian fauna. We discuss the twenty-seven species of amphibian fauna reported from the region and conservation strategies and their importance in the chapter

Nematology - Concepts, Diagnosis and Control

Nematology being an established discipline covers a wide range of area ranging from basic aspect to the advanced and applied aspects involving recent advances in molecular techniques. This book discusses the following topics: the role of nematodes in our life (in agriculture, ecosystem functioning, experimental biology, ecological studies, pest management programs, or biocontrol), identification of GRSPs in nematode genomes, novel way for the diagnosis of pathogenic nematodes involving various recent molecular techniques, other methodologies for successful control of termites, evolution of plant-parasitic nematodes, viability of adult filarial nematode parasites, the impact of plant-parasitic nematodes on crops, and harnessing useful rhizosphere microorganisms for nematode control. The book also encompasses on classical study, molecular study, bioinformatics in nematology, biodiversity analysis, and culturing of nematodes in laboratory condition

Insect Science-Diversity, Conservation and Nutrition

The book discusses the recent advances in basic and applied approaches including research on the genetics of insects, its application in resolving the consequences of world population growth, its impact on agriculture, and control strategies and their implications on the fast-depleting insect resources. The application of insects as a probable nutrient substitute along with the role of sex hormones among insects has been thoroughly discussed. The entire book basically contains five chapters spread over two sections: Section I mainly focuses on diversity, conservation and nutrition, while Section II is concerned with economic importance and up-to-date information on the role of peptides. The book is well illustrated with diagrams, graphical representations and flow charts for easy understanding the important information discussed in the book

Trichoderma - The Most Widely Used Fungicide

Trichoderma is a genus of fungi that are present in all soils, where they are the most prevalent culturable fungi. They are also the most successful biofungicides used in today's agriculture. These green-colored fungi are well known for their antifungal and plant-growth-stimulating effects. This book provides comprehensive information on Trichoderma and its use in medical, agricultural and industrial applications. Section I focuses mainly on identification of Trichoderma species, and Section II is concerned with Trichoderma as a biological control agent. Chapters in these sections cover topics ranging from taxonomic status and biodiversity to biochemical analysis and bio-control application

Survey of Snakes Bites among Snake Endemic Communities in North Eastern Nigeria

Snake envenomation is increasingly recognized as a serious, worldwide public health concern and a neglected tropical disease of global importance especially in the North Eastern Nigeria. The scarcity of data regarding such snake fauna couple with its ability to inflict immense misery to the poorest of the population justifies the need to identify such snakes and some of the clinical features of snakebite victims in these endemic areas. Both primary and secondary data were collected during the study. Result revealed that 10 venomous snake species were reported in Gombe, Taraba and Bauchi state. The most abundant snake species is the Echis ocellantus (Carpet or saw scaled viper) having the highest frequency of encounter followed by the Bitis arientans (Puff Adder) and Naja nigricolis (Black Spiting Cobra). The Kaltungo General Hospital in Gombe is one of the major treatment centers in the North-Eastern Nigeria. About 2945 Human snakebite cases were reported in the Hospital in the year 2018, the highest snake envenoming were observed in October with 16.1% frequency while January has the least snakebite cases of 1.7%. The burden of snakebite envenoming in the North-Eastern Nigeria is a serious public health challenge which desperately need to be addressed
