AbstractLeeches feeding on invertebrates are an important component of freshwater communities, including those dominated by fish, but the effects of fish on their abundance and distribution are not well explored. The relative densities and assemblage

Publikováno v: Zhang, X, Zhen, W, Jeppesen, E, Jensen, H S, Yu, J, Zhou, Q & Liu, Z 2022, ' Benthivorous fish cause a shift from a clear water state established by combining​ phosphorus immobilization and submerged macrophytes to a turbid state : A mesocosm study ', Environmental Technology and Innovation, vol. 28, 102888 . https://doi.org/10.1016/j.eti.2022.102888

Both chemical phosphorus (P) immobilization and submerged macrophytes are widely used in lake restorations to reduce internal phosphorus loading. Their combined effects seem much stronger than used alone. However, benthivorous fish populations recove

Publikováno v: Acta Scientiarum: Biological Sciences, Vol 38, Iss 3 (2016)

This study aimed to assess the diet of Poecilia reticulata in rural (RS) and urban stream (US) and under seasonal influence. We hypothesized that rainfall have a strong negative impact on the diet of the species in the US, due to its abrupt effect on
