Disentangling the Drivers of a Piscivorous Intra‐Annual Cohort and the Contributions of Three Cohorts to Early‐Year Class Strength in Pikeperch (Sander lucioperca)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Using pikeperch (Sander lucioperca) as a model species, we investigated the factors influencing fluctuations in the abundance of piscivorous intra‐annual cohorts and assessed the role of three distinct cohorts: extremely small (ES), ordinary (or mid‐sized) fingerlings, and piscivorous in shaping year‐class strength.

Water availability and land‐use shape the diversity of Odonata in the Middle East

Insect Conservation and Diversity, EarlyView.
Odonata diversity in the Middle East depends on the availability of long‐lasting waters, emphasizing the importance of preserving stable aquatic habitats for biodiversity conservation under climate change‐driven droughts. Agricultural expansion is associated with increased Odonata species richness, but overall trait diversity remains limited ...

Macrophyte Coverage Increases Largemouth Bass Abundance and Trophy Potential: A Resist‐Accept‐Direct (RAD) Application for Aquatic Plant Management in North‐Temperate Lakes

Aquaculture, Fish and Fisheries
Climate change is altering north‐temperate lake ecosystems through warming and increased aquatic macrophyte production. These changes have the potential to cause ecosystem shifts that challenge status quo fisheries management and require the adoption of ...

Macrophytes as biological indicators of organic pollution in the Lepenci River Basin in Kosovo

Journal of Freshwater Ecology, 2020
Macrophytes represent one part of the biological quality elements defined by the European Water Framework Directive (WFD) as ‘macrophytes and phytobenthos’.

Eurasian watermilfoil biomass associated with insect herbivores in New York [PDF]

, 2000
A study of aquatic plant biomass within Cayuga Lake, New York spans twelve years from 1987-1998. The exotic Eurasian watermilfoil ( Myriophyllum spicatum L.) decreased in the northwest end of the lake from 55% of the total biomass in 1987 to 0.4 ...

Relative impacts of morphological alteration to shorelines and eutrophication on littoral macroinvertebrates in Mediterranean lakes [PDF]

, 2015
Development of effective methods for assessing the ecological status of lakes based on littoral benthic fauna has been hampered by the lack of quantitative data on the relative impacts of key pressures on the benthic community.

Aspects of the Histopathology of Clarias gariepinus Infected With the Camallanid Parasite Procamallanus (Procamallanus) pseudolaeviconchus Moravec and Van As, 2015

Journal of Fish Diseases, EarlyView.
ABSTRACT Histopathological studies of infections with the nematode Procamallanus (Procamallanus) pseudolaeviconchus Moravec and Van As, 2015, an intestinal parasite of Clarias gariepinus (Burchell, 1822), are scarce. The current study describes histopathological changes in the stomach of C. gariepinus infected with P.

Benthic fauna dynamics following large‐scale seagrass restoration in an exposed environment

Restoration Ecology, EarlyView.
Seagrass meadows are vital habitats, modifying hydrodynamic energy flows and sustaining biodiversity in the benthic environment. As such, there is a growing interest in using seagrass as a nature‐based solution for coastal adaptation. However, planting seagrass in hydrodynamically exposed environments is challenging, and the trajectories and timescales
