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

open access: yesBoreas, 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 ...

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

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

Specialization directs habitat selection responses to a top predator in semiaquatic but not aquatic taxa

open access: yesScientific Reports, 2021
Habitat selectivity has become an increasingly acknowledged mechanism shaping the structure of freshwater communities; however, most studies have focused on the effect of predators and competitors, neglecting habitat complexity and specialization.

Points vs. passes: A comparison between electric fishing techniques for sampling fish populations in upland headwater streams

open access: yesJournal of Fish Biology, EarlyView.
Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.

Re-Establishment Techniques and Transplantations of Charophytes to Support Threatened Species

open access: yesPlants, 2021
Re-establishment of submerged macrophytes and especially charophyte vegetation is a common aim in lake management. If revegetation does not happen spontaneously, transplantations may be a suitable option.

Vegetation trajectories over 150 years of temporary ponds created in the Camargue delta (Southern France)

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Temporary ponds in the Mediterranean climate have a high conservation value, but many have been severely destroyed or degraded. Pond restoration and new pond creation have been engaged widely. Evaluations of the success of such operations are generally carried out over 10–15 years and show divergent results over this timeframe. In

Effects of restoration on macrophyte and macroinvertebrate ecological status and biodiversity in lowland streams in Denmark

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Habitat restoration is applied to promote ecological recovery in degraded freshwater systems. However, it remains unclear whether stream restoration measures enhance Water Framework Directive (WFD) ecological status and biodiversity.

Nutrients and warm temperatures explain a seasonal cycle of colonization and ecosystem collapse in a floodplain pond

open access: yesEcosphere
Resilient ecosystems maintain similar species diversity and composition despite extreme environmental variation, while ecosystem collapse can be characterized by high mortality rates and decreased species diversity.

Restoration and rehabilitation of floodplain wetlands: a systematic, global review of restoration options and their outcomes

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Floodplain wetlands are vitally important, highly productive, and biodiverse ecosystems. Species dependent on them are facing a range of threats including water extraction, habitat degradation, invasive species, and shifting climates.

Changes in food‐web pathways and ecosystem functions after sidearm re‐connection in a large river (Danube, Austria)

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction River regulation schemes generally led to changes in riverine assemblage composition and their trophic status, which often is reflected in a general loss or decrease of characteristic species and a concomitant increase or dominance of generalist species.
