European scenarios for future biological invasions
The study developed a workflow to downscale global future scenarios to a regional and policy-relevant context. This workflow was applied at the European scale to create four European scenarios of biological invasions until 2050 that consider different environmental, socio-economic and socio-cultural trajectories, namely the European Alien Species Narratives.
Perspectives in modelling ecological interaction networks for sustainable ecosystem management
The study provides perspectives on the use of network models to address a variety of applied ecological questions along spatial and temporal dimensions as well as on interactions between abiotic and biotic components of ecosystems. Through collaborative research, network models could provide important levers for sustainable management.
Universal microbial reworking of dissolved organic matter along environmental gradients
To investigate how dissolved organic matter is degraded in soil and aquatic ecosystems by microorganisms, the authors analyzed its molecular diversity in relation to microbial communities and physicochemical conditions. Changes in DOM composition were consistent across different environments – as degradation progressed, DOM became dominated by universal, hard-to-break-down compounds.
Environmental DNA, hydrochemistry and stable water isotopes as integrative tracers of urban ecohydrology
The authors investigated the variability of planktonic bacteria and benthic diatoms coupled with insights from hydrochemistry and stable water isotopes across four urban streams in Berlin. DNA metabarcoding results shows substantial spatio-temporal variability across urban streams in terms of microbial diversity and richness, with clear links to abiotic factors and nutrient concentrations.

The shape of density dependence and the relationship between population growth, intraspecific competition and equilibrium population density
The authors focused on extensions of the logistic growth model, and how intrinsic rates of increase and equilibrium population densities are not independent, but instead are functions of the same underlying parameters. They highlight several options for modeling population growth, and provide a mechanistic understanding of how the model parameters of each model relate to one another.
Using the IUCN Environmental Impact Classification for AlienTaxa to inform decision-making
The Environmental Impact Classification for Alien Taxa (EICAT) has been adopted as an International Union for Conservation of Nature (IUCN) standard to measure the severity of environmental impacts caused by organisms living outside their native ranges. This article clarifies the underlying principles, objectives, and uses of EICAT.
Developing a conceptual model of groundwater – Surface water interactions in a drought sensitive lowland catchment using multi-proxy data
Increasing droughts require a better understanding of connectivity and groundwater-surface water interactions. The authors used a multi-proxy approach of isotope tracers, groundwater data and geophysics to develop a conceptual model of landscape connectivity and groundwater recharge and assessed the effects of land use and catchment properties of groundwater systems sensitive to climate change.
