Bacterial responses to phytoplankton exudates (DOMp) may be caused by different DOMp compositions. Thereby, the bacterial community leads to a succession of DOMp from highly to less bioavailable, reflected by the temporal presence of specific bacterial phylotypes. The exploitation of species-specific highly bioavailable compounds, results in a more similar remaining DOMp.

This article addresses the concept of attention transience applied to conservation, discusses its major drivers and mechanisms, and provides an overview of conservation issues for which this phenomenon is particularly relevant. Attention transience only leaves a brief window of opportunity to focus public awareness and mobilize support for nature conservation.

Weirs and other transverse structures in rivers not only impede migratory fish on their way to spawning grounds, but even if they are able to pass, many of them die in the turbines of hydroelectric power plants. The authors present a recommendation on how to facilitate effective passage and even promote sturgeon with bypass channels at dams that can serve as additional habitat.

The authors detected great concentrations of source hotspots on the northern regions associated to lentic ecosystems, main European rivers acting as ecological corridors for all freshwaters, and a mixed distribution of connectivity hotspots in southern and Mediterranean ecoregions.

This meta-analysis investigated how parasites affect the consumption rate of their hosts. It is the first comprehensive overview of parasite effects on host feeding capacity and sheds light on the factors contributing to the observed differences.

Empirical studies show divergent impacts of alien populations on ecosystems which hinders the creation of a unified theory. The authors propose a synthesis that categorizes hypotheses along a timeline of invasion considering population, community and ecosystem levels. For any given case study, this framework provides a guide to choose the appropriate concepts according to the stage of invasion.

The authors undertook the first global assessment of the impacts of alien species on native freshwater megafauna using the Environmental Impact Classification for Alien Taxa framework. Negative impacts on native freshwater megafauna were caused by 61 alien species from diverse taxonomic groups, including both freshwater and terrestrial alien species, and both vertebrates and invertebrates.

The authors investigated the effectiveness of Protected Areas (PAs) in conserving amphibians and reptiles under climate change. They found that PAs are effective in providing refuge to these species, but spatial conservation gaps still exist and many species may go extinct due to climate change.
