Corruption is ubiquitous. Recent developments across the globe attest to the fact that abuse of power and office with impunity is not restricted to any part of the world system. Nevertheless, its consequences in the post-colonial African states are pervasive. This explains why the African continent has remained stunted in growth with a huge deficit in human development. Every society has rules and procedures designed to promote the interests of the collective. Adherence to these rules requires appropriate actions and sanctions from both the ruled and the rulers.

Carolyn Anglin Anglin and Associates Supervisory Committee Member iii Abstract Primary successional post-mining landscapes present physical, chemical and biological barriers to terrestrial ecosystem recovery.

I investigated if legacies of the pre-disturbance ecosystem can be applied to help overcome these barriers, leveraging the processes that guide succession following natural disturbances. In a three-year field experiment at the Mount Polley Mine, Canada and in a greenhouse experiment using tailings, overburden and forest soil from the mine, I tested if 1 adding small volumes of forest soil to the seedling rooting zone during planting and 2 spatial connectivity with undisturbed forest would improve soil food web recovery and plant establishment. In the field, soil additions Effects Of Post Colonialism In Nigeria soil faunal diversity and caused bacterial Efects shifts consistent with advancing succession, with greater benefits in lower quality soils. Sterilized greenhouse controls revealed that a later successional conifer benefited primarily from the biological inoculum, while an early successional shrub benefited more from the improved soil physiochemical conditions.

Greater proximity to undisturbed forest increased plant diversity and shifted soil microbial communities, showing that Posh patches of intact ecosystems can counteract dispersal limitations. Field-testing of soil additions and spatial connectivity in conjunction with site preparation showed that application Successful Engineer A ecosystem legacies can have additive benefits with reclamation methods targeting soil physical improvements. I found negative feedbacks due to fungal pathogen accumulation promoted turnover of an early successional shrub, while formation of distinct mycorrhizal fungal communities selectively promoted establishment and stability of compatible later successional tree species.

This reinforces that reclamation plant species selection can influence long-term plant community assembly.

The Nigerian Post

Ecosystem legacy-based mine reclamation methods could be used operationally to simultaneously enhance dispersal and establishment of native plants and soil organisms, which, over the long-term, is anticipated to have positive feedbacks on ecosystem recovery. I demonstrated that remnants of the pre-existing forest can be used in mine reclamation to help plants reestablish. Firstly, adding small volumes read more fresh forest soil to the rooting zone of seedlings during planting improved seedling establishment and increased colonization of seedling roots by mycorrhizal fungi beneficial microbes that improve plant nutrient acquisition.

Secondly, greater proximity to undisturbed forest enhanced dispersal and recovery of Nigera communities and soil microbes. I also found that plants growing in mining waste formed distinct communities of mycorrhizal fungi.

This selectively promoted establishment of tree species Pst are compatible with those mycorrhizal fungi, highlighting the long-term implications of plant species selection in reclamation. My research advanced our understanding of the role of soil microbes in mine reclamation and identified reclamation methods that can improve plant establishment by promoting recovery of beneficial soil microbes.]
