Diet-tissue discrimination factors of three neotropical freshwater fishes and a comparison of the trophic position

Journal of Limnology, 2023
The trophic discrimination factor (TDF) is a key parameter for stable isotope analysis and due to a lack of species-specific TDFs, mean universal values have been used, resulting in uncertainties about the trophic position of species and a call for more

River Damming Impacts on Fish Habitat and Associated Conservation Measures

Reviews of Geophysics, Volume 61, Issue 4, December 2023., 2023
Abstract River damming has brought great benefits to flood mitigation, energy and food production, and will continue to play a significant role in global energy supply, particularly in Asia, Africa, and South America. However, dams have extensively altered global river dynamics, including riverine connectivity, hydrological, thermal, sediment and ...

Genetic variability of pure Pseudoplatystoma corruscans and Pseudoplatystoma reticulatum individuals in the Paraná and Paraguay River basins [PDF]

Fisheries Science, 2016
The presence of interspecific hybrid surubim (Pseudoplatystoma corruscans × Pseudoplatystoma reticulatum) in natural environments can put at risk the existence of the pure parental lineages. The aim of this study was to characterize the genetic variability of pure Pseudoplatystoma corruscans and Pseudoplatystoma reticulatum individuals from rivers in ...

Dynamic Adaptive Environmental Flows (DAE‐Flows) to Reconcile Long‐Term Ecosystem Demands With Hydropower Objectives

Water Resources Research, Volume 59, Issue 7, July 2023., 2023
Abstract This study investigates how environmental flows (e‐flows) can be designed as dynamic operating policies to optimize long‐term economic and ecosystem performance in reservoir systems. The main goal is to provide e‐flow solutions that contribute to better preparedness and flexibility of hydro‐systems to face multiyear stress periods, reducing ...

Isotopic turnover in polar cod (Boreogadus saida) muscle determined through a controlled feeding experiment

Journal of Fish Biology, Volume 102, Issue 6, Page 1442-1454, June 2023., 2023
Abstract Polar cod (Boreogadus saida) is an important trophic link within Arctic marine food webs and is likely to experience diet shifts in response to climate change. One important tool for assessing organism diet is bulk stable isotope analysis. However, key parameters necessary for interpreting the temporal context of stable isotope values are ...
