The effects of operational conditions on the respiration rate of Tubificidae. [PDF]

PLoS ONE, 2013
Tubificidae is often used in the wastewater treatment systems to minimize the sludge production because it can be fed on the activated sludge. The process conditions have effect on the growth, reproduction, and sludge reduction efficiency of Tubificidae.

Effects of short-term exposure to Pomacea canaliculata secretions on Limnodrilus hoffmeisteri and Propsilocerus akamusi: A study based on behavior, intestinal microbiota, and antioxidant system. [PDF]

Ecol Evol
Pomacea canaliculata affected bioturbators' behavior, antioxidant system, and gut microbiota; Secretions changed the intestinal microbiota community structure of bioturbators; Limnodrilus hoffmeister is a more sensitive bioturbator to the invasion of P. canaliculata.

Effect of Pomacea canaliculata on Limnodrilus hoffmeisteri: Behavior, Oxidative Stress, and Microbiota Alterations. [PDF]

Ecol Evol
Behavior pattern changes of L. hoffmeisteri exposed to non‐free Pomacea canaliculata (PC) were found PC caused oxidative stress in L. hoffmeisteri PC changed the intestinal microbiota community structure of L. hoffmeisteri Aeromonas from the intestinal tract of P. canaliculata (As) had similar effects. As is the main stress source.

COVID-19 Lockdown Pandemic Period Effects in Highly Impacted Aquatic Ecosystems. [PDF]

Environ Toxicol Chem, 2023
Abstract Human activities severely affect aquatic ecosystems: the lockdown restrictions due to SARS‐CoV‐2 (COVID‐19) have proved that reducing anthropogenic activities can positively influence the environment and mitigate atmospheric pollution. In addition, studies on aquatic ecosystems have highlighted the decrease in suspended matter and pollutant ...

Response of macroinvertebrate communities to land use and water quality in Wudalianchi Lake. [PDF]

Ecol Evol, 2021
Our study indicated that both the independent effects of land use and within‐lake water quality can explain the influence in macroinvertebrate assemblages, with significant interactions between the two. This is rather important to notice that changes in buffer land use generally may alter nutrient inputs and thus severely affect abiotic conditions ...
