Using ciliates as indicators

sciencewithevie

Protozoa ciliates community structure in urban streams and their environmental use as indicators SUMMARY: Three urban stream samples were collected during both dry and rainy seasons in Brazil. Ciliates were classified and identified in each stream. The relationships between the ciliates, abiotic factors, and biotic factors are discussed in the last section of the paper.… Continue reading Using ciliates as indicators

Conservation of biodiversity to improve human well-being

sciencewithevie

Conservation of biodiversity as a strategy for improving human health and well-being SUMMARY: This article looks at the concept that increasing biodiversity in an ecosystem can decrease the prevalence of diseases. While the idea seems simple (more hosts for the disease, less incidences of the disease spreading to people), the issue is much more complicated.… Continue reading Conservation of biodiversity to improve human well-being

Protozoa in Wastewater Treatment Processes

sciencewithevie

Protozoa in wastewater treatment processes: A minireview SUMMARY: This is a short review of the role protozoa play in wastewater treatment plants. Most of the protozoa are ciliates and they graze on bacteria, excrete nitrogen, phosphorus, and carbon waste, and are used as indicators of water quality. Toxins such as heavy metals, salts, and other… Continue reading Protozoa in Wastewater Treatment Processes

Crops and Climate Change

sciencewithevie

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

sciencewithevie

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

Krill Digesting Microplastic

sciencewithevie

Turning microplastics into nanoplastics through digestive fragmentation by Antarctic krill SUMMARY: This study found that krill were breaking down microplastic beads into smaller and smaller pieces in their digestive system. The krill were divided into two groups, one eating 80% plastic beads with 20% algae, the other eating 20% plastic beads and 80% algae. The… Continue reading Krill Digesting Microplastic
