Insights into the phylogeny of the ciliate of class Colpodea based on multigene data

open access: yesEcology and Evolution, 2022
In the class Colpodea, there are many unresolved evolutionary relationships among taxa. Here, we report 30 new sequences including SSU‐rRNA, ITS1‐5.8S‐ ITS2 rRNA, and the mitochondrial small subunit ribosomal RNA (mtSSU‐rRNA) genes of five colpodeans ...

Applications of next-generation sequencing technologies and computational tools in molecular evolution and aquatic animals conservation studies : a short review [PDF]

open access: yes, 2019
Aquatic ecosystems that form major biodiversity hotspots are critically threatened due to environmental and anthropogenic stressors. We believe that, in this genomic era, computational methods can be applied to promote aquatic biodiversity conservation ...

Impact of organic contamination on some aquatic organisms

open access: yesToxicology International, 2015
Contamination of water systems with organic compounds of agricultural uses pose threats to aquatic organisms. Carbaryl, chlorpyrifos, and diuron were considered as model aquatic pollutants in this study. The main objective of this study was to characterize the toxicity of organic contamination to two different aquatic organisms.Low concentrations (0.0 ...

Aquatic Organisms in Nattrinai

open access: yesInternational Research Journal of Tamil, 2022
There are many kinds of organisms living in different environments in the world. They had a physique according to the environment in which they lived and had food habits for their respective environments. Just as on land, there are living creatures in the water. In the Sangam age, there were more species living in Sangam age than in today's time.
