Rotifers Paralyzing Schistosomes

GwynneL.

A rotifer-derived paralytic compound prevents transmission of schistosomiasis to a mammalian host SUMMARY: Researchers discovered that a new molecule produced by the rotifer, Rotaria rotatoria, paralyzes cercariae. Cercariae are the free-living/infectious stage of the flatworm Schistosoma, the cause of schistosomiasis. R. rotatoria live on the shell of freshwater snails and secrete a compound scientists have… Continue reading Rotifers Paralyzing Schistosomes

Crops and Climate Change

GwynneL.

Impact of Climate Change on Crops Adaptation and Strategies to Tackle Its Outcome: A Review (NOT OPEN ACCESS) SUMMARY: This is a review on how climate change can affect agriculture. The first six sections talk about changes in crop production, plants adapting to heat and drought, metabolic changes in plants due to increases in CO2,… Continue reading Crops and Climate Change

Rotifers Eating Bacteria to Clean Water

GwynneL.

Foam-forming bacteria in activated sludge effectively reduced by rotifers in laboratory- and real-scale wastewater treatment plant experiments SUMMARY: This article looks at using rotifers as a way to control a specific type of filamentous bacteria in wastewater treatment plants. Overgrowth of this bacteria leads to foam and inefficient break down of waste by other microorganisms.… Continue reading Rotifers Eating Bacteria to Clean Water
