Fish behaviour is one biological organisational level regularly used to assess the state of freshwater ecosystems and can be monitored using fish telemetry methods. The development of activity sensors incorporated into fish telemetered tags allows for non-spatial movement to be detected and is increasingly used to understand the energy budgets and response and fine-scale behaviour of fishes. In addition

What you hear may not be what you see: Potential of citizen science methods to use bats as riverine forest quality indicators River Res. Appl. (IF 2.2) Pub Date : 2023-09-22 David López-Bosch, Estel Blanch, Ferran Páramo, Carles Flaquer-Sánchez, Adrià López-Baucells
Mediterranean habitats will be one of the Eurasian ecosystems more strongly affected by Climate Change, especially their riverine systems. Monitoring these ecosystems, which are endemism hotspots and extremely sensitive to changes in rain regimes and extreme weather events like droughts, is of crucial importance. Decades of citizen science projects have proven their utility in highlighting ecological

Expansive, positive changes to fish habitat diversity following the formation of a valley plug in a degraded desert river River Res. Appl. (IF 2.2) Pub Date : 2023-09-22 Tansy T. Remiszewski, Phaedra Budy, William W. Macfarlane
Widespread hydrologic alterations have simplified in-stream habitats in rivers globally, driving population declines and extirpations of many native fishes. Here, we examine how rapid geomorphic change in a historically degraded desert river has influenced habitat diversification and ecosystem persistence. In 2010, a large reach of the degraded and simplified lower San Rafael River (SRR), Utah, was

Effect of flow regulation on streambank erosion: A perspective downstream of a flood control dam, Kansas, USA River Res. Appl. (IF 2.2) Pub Date : 2023-09-15 Kari A. Bigham, Tim D. Keane, Trisha L. Moore
While large dams provide society with many benefits, there are many environmental trade-offs. One trade-off of dam installation is the morphologic changes that ensue in the downstream channel. Channel widening due to streambank erosion is a common response to flow regulation (FR), but dominant erosion processes and rates have rarely been evaluated downstream of dams. This case study investigates how

Assessing the effects of non-stationarity on reservoir yield estimations: A case study of the Southern Okavango Integrated Water Development system in Botswana River Res. Appl. (IF 2.2) Pub Date : 2023-09-14 Dominic Mazvimavi, Evison Kapangaziwiri, Anesu Dion Gumbo
Streamflow data used for water resources planning should ideally be stationary, and any non-stationary behaviour is taken into account. However, with limited time series data, the influence of non-stationarity is often hidden and can result in unreliable estimates. This paper examines the impact of non-stationarity on the Southern Okavango Integrated Water Development (SOIWD) project that was carried
