Genetic diversity of Entamoeba in cockroaches

Genetic diversity of Entamoeba: Novel ribosomal lineages from cockroaches SUMMARY: Researchers in this study looked at the diversity of Entamoeba in 3 different species of cockroaches (the American roach, the Dubia roach, and the Madagascar hissing roach) by looking at SSU rDNA in the ground up intestines of the cockroaches. They found that the Entamoebas… Continue reading Genetic diversity of Entamoeba in cockroaches

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 whether or not 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

Environmental DNA sequencing primers for eutardigrades and bdelloid rotifers

Environmental DNA sequencing primers for eutardigrades and bdelloid rotifers SUMMARY: This article talked about using soil eutardigrades and bdelloid rotifer primers to quickly and easily identify these organisms directly. Due to the fact that there are so many types of microorganisms in soil, many of which are still unidentified and unable to be cultured in… Continue reading Environmental DNA sequencing primers for eutardigrades and bdelloid rotifers

Frequency of Microplastics in Mesopelagic Fishes from the Northwest Atlantic

Frequency of Microplastics in Mesopelagic Fishes from the Northwest Atlantic SUMMARY: In this experiment, the researchers sampled dead mesopelagic fish from the Northwest Atlantic Mid-Ocean area (between Ireland and Newfoundland). The water and the fish guts were strained for microplastics. Researchers found that 73% of the fish had microplastics in their stomach. Most of the… Continue reading Frequency of Microplastics in Mesopelagic Fishes from the Northwest Atlantic

How Bacteria Genes Change with Dryness

Environmental filtering of bacterial functional diversity along an aridity gradient SUMMARY: Genes of soil bacteria sampled in the Tibetan Plateau showed that as the environment got drier, the less diverse the genes were. Researchers wanted to compare bacterial gene diversity with the already-known diversity of genes in large animals in various environments. There were less… Continue reading How Bacteria Genes Change with Dryness
