Changes in the taxonomic structure of periphytic algae on a free-floating macrophyte (Utricularia foliosa L.) in relation to macrophyte richness over seasons

open access: yesActa Botânica Brasílica, 2018
Periphyton has a strong relationship with aquatic macrophytes, which are key components of spatial heterogeneity in the littoral zone. We evaluated the relationship between the community structure of periphytic algae on Utricularia foliosa and macrophyte

Driver-pressure-impact and response-recovery chains in European rivers: observed and predicted effects on BQEs [PDF]

open access: yes, 2011
The report presented in the following is part of the outcome of WISER’s river Workpackage WP5.1 and as such part of the module on aquatic ecosystem management and restoration. The ultimate goal of WP5.1 is to provide guidance on best practice restoration

Juvenile and Adult Three‐Spined Sticklebacks Exhibit Different Habitat Use in Shallow Baltic Sea Bays

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Three‐spined sticklebacks (Gasterosteus aculeatus) have become dominant in many Baltic Sea coastal fish assemblages, yet life‐stage‐specific habitat use remains poorly understood. We surveyed shallow water habitats along the coast of Gotland, Sweden, to examine how juvenile and adult stickleback abundances relate to variables such as submersed

Effects of climate on size structure and functioning of aquatic food webs [PDF]

open access: yes, 2010
In aquatic food webs, the role of body size is notoriously strong. It is also well known that temperature has an effect on body size. For instance, Bergmann’s rule states that body size increases from warm to cold climates.

Efficient sampling methodologies for lake littoral invertebrates in compliance with the European Water Framework Directive [PDF]

open access: yes, 2015
Lake shores are characterised by a high natural variability, which is increasingly threatened by a multitude of anthropogenic disturbances including morphological alterations to the littoral zone. The European Water Framework Directive (EU WFD) calls for

Development and Research Progress of the ‘Land‐Based Container + Ecological Pond’ Recirculating Aquaculture Model in China

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
This review systematically examines China's Land‐based Container + Ecological Pond (LCEP) recirculating aquaculture model. It synthesizes the system's development, technical principles, and research progress, highlighting its significant resource savings (>75% land, >90% water) and high‐density production capabilities. The analysis critically evaluates

Local ciliate communities associated with aquatic macrophytes [PDF]

open access: yes, 2014
This study, based within the catchment area of the River Frome, an important chalk stream in the south of England, compared ciliated protozoan communities associated with three species of aquatic macrophyte common to lotic habitats: Ranunculus ...

Sedimentary Metagenomics Reveal Avian Community Transitions From the Last Glacial Maximum to the Holocene

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We used sedimentary ancient DNA shotgun metagenomics to reconstruct past bird communities in northern high‐latitude environments. By using long time series and data collected across a large environmental gradient, we contributed in a unique and explorative way to the understanding of palaeoecological dynamics between birds and their habitat on the ...
