Effects of Invasive Watermilfoil on Primary Production in Littoral Zones of North-Temperate Lakes

open access: yesDiversity, 2020
Species invasions are changing aquatic ecosystems worldwide. Submerged aquatic macrophytes control lake ecosystem processes through their direct and indirect interactions with other primary producers, but how these interactions may be altered by ...

Temporal and spatial variation of limnological variables and biomass of different macrophyte species in a Neotropical reservoir (São Paulo - Brazil) [PDF]

open access: yes, 2013
Aim: This study reports an investigation of limnological characteristics and aquatic macrophyte occurrence in a neotropical reservoir in order to assess the spatio-temporal variation of water and sediment variables and their influence on plant ...

Utilization of fish gut analysis to elucidation of microcrustacean

open access: yesJournal of Ecology and Environment, 2014
Structural heterogeneity results in different spatial distributions of microcrustaceans. Thus, in ecosystems with excessive macrophyte development, it may be difficult to determine the microcrustacean species composition.

Resistance and reconfiguration of natural flexible submerged vegetation in hydrodynamic river modelling [PDF]

open access: yes, 2015
In-stream submerged macrophytes have a complex morphology and several species are not rigid, but are flexible and reconfigure along with the major flow direction to avoid potential damage at high stream velocities.

New Records for \u3ci\u3eEuhrychiopsis Lecontei\u3c/i\u3e (Coleoptera: Curculionidae) and Their Densities in Wisconsin Lakes [PDF]

open access: yes, 2018
The native aquatic weevil, Euhrychiopsis lecontei is currently being researched as a potential biological control for the exotic aquatic macrophyte Eurasian watermilfoil (Myriophyllum spicatum), yet little is known about its specific distribution in ...

Quantifying measures to limit wind driven resuspension of sediments for improvement of the ecological quality in some shallow Dutch lakes [PDF]

open access: yes, 2012
Although phosphorus loadings are considered the main pressure for most shallow lakes, wind-driven resuspension can cause additional problems for these aquatic ecosystems. We quantified the potential effectiveness of measures to reduce the contribution of

Potential uptake of dissolved organic matter by seagrasses and macroalgae [PDF]

open access: yes, 2011
Dissolved organic nitrogen (DON) acts as a large reservoir of fixed nitrogen. Whereas DON utilization is common in the microbial community, little is known about utilization by macrophytes.

Every Start is Challenging: Fitting A New Artificial Lake Into the Landscape, Zalakaros, Hungary

open access: yesJournal of Environmental Geography, 2018
The aim of this study is to conclude the experiences of the maintenance practice of an artificial thermal lake. The first years (2015-2017) of the development of the lake were analysed and evaluated along the following questions: a) What kind of design ...
