Statistical modelling of aquatic size spectra: integrating data from multiple taxa and sampling methods Aquat. Ecosyst. Health Manag. (IF 0.8) Pub Date : 2024-02-01 Henrique Corrêa Giacomini, Derrick T. de Kerckhove, Victoria Kopf, Cindy Chu
Size spectra are used to assess the status and functioning of marine and freshwater ecosystems worldwide. Their use is underpinned by theory linking the dynamics of trophic interactions to a power-law decline of abundance with body size in ecological communities. Recent papers on empirical size spectrum estimation have argued for Maximum Likelihood Estimation of power-law probability distributions

Strategic plan to restore a shallow overgrowing macrophyte lake Aquat. Ecosyst. Health Manag. (IF 0.8) Pub Date : 2024-02-01 Kairi Maileht, Tiina Nõges, Ronald Laarmaa, Maili Lehtpuu, Margot Sepp, Leho Luigujõe, Katrin Saar, Teet Krause, Madis Metsur, Kalev Raadla, Kaarel Võhandu, Priit Zingel, Peeter Nõges, Ingmar Ott
As a result of natural and anthropogenic eutrophication, shallow lakes ultimately become wetlands. Several aquatic ecosystem values diminish, but some biotic communities may benefit. Lake Lahepera is a very shallow lake filled with sediments and overgrown with macrophytes. It is a former bay and an important spawning ground for fishes of Lake Peipsi, the fourth largest lake in Europe. The main question

Modelling effects of nutrients and hypoxia on Lake Erie's central basin foodweb Aquat. Ecosyst. Health Manag. (IF 0.8) Pub Date : 2024-02-01 Hongyan Zhang, Doran M. Mason, Edward S. Rutherford, Marten A. Koops, Timothy B. Johnson, Ann Marie Gorman, Mark Rowe, Xinhua Zhu, Monir Hossain, H. Andrew Cook
Hypoxia (dissolved oxygen < 2 mg l-1) has long been a prevalent feature of the central basin of Lake Erie. Studies of the sublethal impacts of hypoxia on fishes have focused on individual species feeding rates, behavior and spatial distributions over short time periods, but the long-term effects on the fish community and its foodweb are poorly known. Sublethal effects of hypoxia on fish include: interrupting

Inland rift valley lake systems have been sustaining humanity for a long time. Only recently have commercial fisheries entered these systems and for Lake Malawi, this occurred in the mid-1970s upon successful experimental trawl fishing. Lake Malawi with the highest diversity of freshwater fishes in the world has had fisheries for centuries. Previous assessment of the impact of commercial trawl fisheries
