Blooms of freshwater toxic cyanobacteria are a growing environmental health problem, enhanced by anthropogenic eutrophication and climate change. A variety techniques were tested for their remediation, from physical methods using artificial mixing or flocculation, to chemical employing synthetic natural compounds, as well constructed wetlands. In this work, we conducted an evaluation at microco...

As exemplified by classic Lotka–Volterra theory, there are several canonical outcomes possible to a two species (interference) competitive interaction: coexistence, initial condition-dependent competitive exclusion of one species, or the global exclusion of one species. Evolutionary versions of Lotka–Volterra dynamics have been investigated in order to see the role that evolutionary adaptation ...

Biological control of aflatoxin contamination by Aspergillus flavus is achieved through competitive exclusion of aflatoxin producers by atoxigenic strains. Factors dictating the extent to which competitive displacement occurs during host infection are unknown. The role of initial host contact in competition between pairs of A. flavus isolates coinfecting maize kernels was examined. Isolate succ...

Reproductive interference is one of the major factors mediating species exclusion among insects. The cryptic species Middle East-Asia Minor 1 (MEAM1) and Mediterranean (MED) of the whitefly Bemisia tabaci complex have invaded many parts of the world and often exhibit niche overlap and reproductive interference. However, contrasting patterns of competitive displacement between the two invaders h...

In biogeography the competitive exclusion principle (CEP) has been confirmed in some cases but not others. This fueled an unresolved debate between those advocating niche theory or neutral biodiversity and biogeography. We suggest that this situation mainly arises from use of crisp logic, where CEP is defined as either completely true false. propose application fuzzy concepts favorability (the ...
