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

Insights into transgenerational epigenetics from studies of ciliates

Insights into transgenerational epigenetics from studies of ciliates SUMMARY: This article summarizes what we know about ciliate epigenetics so far. The first section is an introduction to their weird nucleus situation: ciliates have two types of nuclei, the macronucleus and the micronucleus. Several examples of ciliate epigenetics are given in sections 2 and 3. Some… Continue reading Insights into transgenerational epigenetics from studies of ciliates

Relationship between the flagellates and the ciliates

Relationship between the flagellates and the ciliates SUMMARY: This is an article comparing the structural and genomic differences between ciliates and flagellates. Dinoflagellates seem to be the ancestors of ciliates based on similarities in various cell structures and rRNA sequencing. Structures compared in this article include: mitochondria, mechanisms of cilia and flagella, nucleus, and how… Continue reading Relationship between the flagellates and the ciliates
