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 ...

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

open access: yesFisheries 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.

Oxygen demand during mineralization of aquatic macrophytes from an oxbow lake

open access: yesBrazilian Journal of Biology
This study presents a kinetic model of oxygen consumption during aerobic decomposition of detritus from seven species of aquatic macrophytes: Cabomba furcata, Cyperus giganteus, Egeria najas, Eichhornia azurea, Salvinia auriculata, Oxycaryum cubense and ...

Submerged Macrophytes Exhibit Different Phosphorus Stoichiometric Homeostasis

open access: yesFrontiers in Plant Science, 2018
Phosphorus (P) is a limiting element in many aquatic ecosystems. Excessive P input often leads to cyanobacterial bloom, thus triggering ecological imbalances and a series of environmental problems.

Low breeding propensity in a declining Arctic‐breeding swan revealed by telemetry data

open access: yesIbis, EarlyView.
Many migratory bird populations are declining in the face of habitat degradation and climate change, making it important to identify which stages of their annual cycle are most affected in order to guide conservation measures. The Bewick's Swan Cygnus columbianus bewickii, an Arctic‐breeding waterfowl species, has suffered a dramatic population decline

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.

For colonization success, should hosts and microbes travel alone, together, or swap partners along the way?

open access: yesNew Phytologist, EarlyView.
Experimental co‐introduction of duckweeds (Lemna japonica) and their microbiome in a common pond. Summary Microbiomes that enhance the performance of host plants are likely to be co‐introduced with their host during colonization because of their intimate association.

Morpho‐anatomical and genetic variation of Lithophyllum neo‐okamurae and L. okamurae (Corallinales, Corallinophycidae, Rhodophyta) from Jeju Island, Korea

open access: yesPhycological Research, EarlyView.
SUMMARY Lithophyllum Philippi (Corallinales, Corallinophycidae, Rhodophyta) is a diverse genus of non‐geniculate coralline algae. Lithophyllum neo‐okamurae and L. okamurae are commonly found in the intertidal and subtidal zones of Jeju Island, Korea, where they contribute to local benthic communities.

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
