Role of the propagule bank in reestablishing submerged macrophytes after removal of free-floating plants for recovery of a shallow lake in Southern Brazil

Ecología Austral, 2020
At eutrophic shallow subtropical lakes, free-floating macrophytes can occupy the entire water surface. The removal of this vegetation favors the recolonization of submerged macrophytes from the propagule bank.

Geometric Morphometrics Reveal Body Shape Variation in Freshwater Shrimps of the Genus Macrobrachium Lacking a Mandibular Palp (Formerly Pseudopalaemon Sollaud, 1911) (Decapoda: Palaemonidae)

Acta Zoologica, EarlyView.
ABSTRACT Shape variation in the cephalothorax of Macrobrachium species without mandibular palp using geometric morphometrics was used as a tool to support species differentiation and propose new diagnostic characters for taxonomic identification.

Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

Boreas, EarlyView.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...

Effects of Warming and Phosphorus Enrichment on the C:N:P Stoichiometry of Potamogeton crispus Organs

Frontiers in Plant Science, 2022
The loss of submerged macrophytes from freshwater ecosystems is accelerating owing to the combined effects of eutrophication and climate change. Submerged macrophytes depend on spring clear water; however, increased water temperatures and excessive ...

Capture Probability and Effects of Bait Type on Learning Behavior in an Unexploited Population of Northern Pike (Esox lucius)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Changes in angling response were studied over a period of three years in a natural, previously unfished population of northern pike. Standardized angling sessions took place during two weeks in spring and autumn with three bait types: bright‐ and natural‐colored soft plastic baits and a dead baitfish.

The effects of nutrient level on periphyton–macrophyte interactions in freshwater ecosystems

Water Biology and Security
Periphyton are one of the key primary producers in aquatic ecosystems, particularly in oligotrophic shallow lakes. Submerged macrophytes are capable of competing with periphyton for nutrients and light, but may also facilitate periphyton by providing ...

Dynamics of primary productivity in relation to submerged vegetation of a shallow, eutrophic lagoon: A field and mesocosm study.

PLoS ONE, 2021
Aquatic ecosystems nowadays are under constant pressure, either from recent or historical events. In most systems with increased nutrient supply, submerged macrophytes got replaced by another stable state, dominated by phytoplankton as main primary ...

Dragonfly taxonomic and functional responses to urbanized streams in southeastern Europe, with management recommendations

Insect Conservation and Diversity, EarlyView.
Urbanization drives turnover in dragonfly species composition, traits, and habitat conservation value. Natural stream sections have a higher conservation value (higher DBI) due to presence of specialists. Properly managed urban streams can support diverse dragonfly assemblages.

Species-specific functional trait responses of canopy-forming and rosette-forming macrophytes to nitrogen loading: Implications for water–sediment interactions

Environment International
Globally intensified lake eutrophication, attributed to excessive anthropogenic nitrogen loading, emerges as a significant driver of submerged vegetation degradation.
