Abstract: In recent times, the academic ecosystem has seen a tremendous growth in number of authors and publications. While most temporal studies in this area focus on evolution of coauthor and citation network structure, this systemic inflation has received very little attention.

However, there are still a very large number of indicators, perhaps the majority, most specifically th...

The need to have an improved knowledge on the bioecology of Culex quinquefasciatus, a prerequisite in the development of cost-effective control strategies, has informed the present preliminary investigation to put in better perspective variations that exist in the egg rafts of the species. Freshly laid egg rafts were collected and incubated at ambient temperature in well-labeled plastic trays. ...

In the recent past there has been concern to address the declining trends and deteriorating ecological elements and their functions in productive agricultural landscapes.
