Contrasting the effects of microplastic types, concentrations and nutrient enrichment on freshwater communities and ecosystem functioning

Autor: Danielle J. Marchant, Ana Martínez Rodríguez, Pascaline Francelle, John Iwan Jones, Pavel Kratina

Publikováno v: Ecotoxicology and Environmental Safety, Vol 255, Iss , Pp 114834- (2023)

Microplastics are now ubiquitous in freshwater environments. As most previous research has focused on species-specific effects of microplastics under controlled laboratory conditions, little is known about the impact of microplastics at higher levels

Anthropogenic nutrient loading affects both individual species and the trophic structure of river fish communities

Autor: Petra Horka, Zuzana Musilova, Katerina Holubova, Katerina Jandova, Jaroslav Kukla, Jitka Rutkayova, John Iwan Jones

Publikováno v: Frontiers in Ecology and Evolution, Vol 10 (2023)

Although the concept of trophic interactions has been used for a long time, there are still considerable gaps in our understanding of the effect of various environmental factors on trophic interactions within river fish assemblages. Carbon (δ13C) an

Biodiversity assessment across a dynamic riverine system: A comparison of eDNA metabarcoding versus traditional fish surveying methods

Autor: Jane Hallam, Elizabeth L. Clare, John Iwan Jones, Julia J. Day

Publikováno v: Environmental DNA, Vol 3, Iss 6, Pp 1247-1266 (2021)

Abstract While many studies have considered the ability of eDNA to assess animal communities in lacustrine settings, fewer have considered riverine systems, particularly those spanning the environmental gradients present in large river basins. Such d

Publikováno v: Journal of Fish Biology. 102:721-726

In spring 2022, pink salmon Oncorhynchus gorbuscha smolts were recorded in the UK. Fish were caught in the Rivers Thurso and Oykel in Scotland between 13 and 17 March. To our knowledge, this is the first observation of O. gorbuscha smolts in Europe o

The Impact of Metal-Rich Sediments Derived from Mining on Freshwater Stream Life

Autor: John Iwan, Jones, John F, Murphy, Adrian L, Collins, Kate L, Spencer, Philip S, Rainbow, Amanda, Arnold, James L, Pretty, Arabella M L, Moorhouse, Victor, Aguilera, Paul, Edwards, Fred, Parsonage, Hugh, Potter, Paul, Whitehouse

Publikováno v: Reviews of environmental contamination and toxicology. 248

Metal-rich sediments have the potential to impair life in freshwater streams and rivers and, thereby, to inhibit recovery of ecological conditions after any remediation of mine water discharges. Sediments remain metal-rich over long time periods and
