ABSTRACT The Winam Gulf in the Kenyan region of Lake Victoria experiences prolific, year-round cyanobacterial harmful algal blooms (cyanoHABs) which pose threats to human, livestock, and ecosystem health. To our knowledge, there is limited molecular research on gulf’s cyanoHABs, thus, strategies employed for survival proliferation by toxigenic cyanobacteria this remain largely unexplored. Here, we used metagenomics analyze Gulf’s composition, function, biosynthetic potential. Dolichospermum...

Forced evictions are widespread in Kenyan cities and are, on the surface, caused by conflicts land rights, non–payment of excessive house rents, urban redevelopment. But, more fundamentally, due to factors embedded country’s political economy, particular, grossly inequitable ownership structure which makes it difficult for poor access decent shelter. Evictions cause significant socioeconomic hardship individuals, affecting whole nations. To avoid evictions, I argue that Kenya must make its...

Despite the global expansion of cyanobacterial harmful algal blooms (cHABs), research is biased to temperate systems within north, such as Laurentian Great Lakes. This lack diversity represents a significant gap in field and jeopardizes health those who reside along at-risk watersheds south. The African Lake, Lake Victoria, understudied despite serving second largest lake by surface area demonstrating year-round cHABs. Here, we address this knowledge performing molecular survey cHAB...
