Using ciliates as indicators

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

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

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

Investigating Microplastics on Land

Microplastics as an emerging threat to terrestrial ecosystems (NOT OPEN ACCESS) SUMMARY: Though there has been a lot of research on microplastics in aquatic environments, there aren’t studies looking into the effects of microplastics on land. Researchers in this article suspect that there may be more microplastics in land than in the oceans; organisms that… Continue reading Investigating Microplastics on Land

Krill Digesting Microplastic

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
