Inland navigation and land use interact to impact European freshwater biodiversity
Using a comprehensive set of long-term data, the authors show that shipping has contributed to a significant loss of biodiversity of fish and macroinvertebrates in European rivers in recent decades – and that the animal communities are becoming increasingly homogeneous and river-typical species are being lost. Invasive species, on the other hand, are significantly increasing.
The potential of citizen science to transform science: Lessons for a sustainable future
The authors analysed 8 citizen science projects within Accelerator Programme of the EU H2020 funded ACTION project that deal with environmental pollution. Citizen science involves the public in the scientific process, making research more relevant and responsive. Our findings show that this can lead to a more sustainable future, where science and society work together to solve pressing problems.
Global introductions and environmental impacts of freshwater megafish
The authors investigated the introductions of freshwater megafish on a global scale and assessed their environmental impacts. Of the 134 extant freshwater megafish species, 46% have been introduced to new environments, and of these, 69% have established self-sustaining alien populations and posed negative impacts on native species through nine different mechanisms.
A scenario-guided strategy for the future management of biological invasions
The study used a scenario-based approach to explore management options for invasive species in Europe. During two workshops involving a multidisciplinary team of experts, a management strategy arranged into 19 goals relating to policy, research, public awareness, and biosecurity was developed considering different future scenarios of biological invasions.
Flagship events and biodiversity conservation
While flagship species are a highly effective approach in conservation, this article proposes the distinct but complementary concept of flagship events: natural or anthropogenic occurrences that attract public attention. Flagship events have high potential value for biodiversity conservation by engaging people with wildlife and helping to garner support for conservation efforts.
Quantitative description of six fish species’ gut contents and prey abundances in the Baltic Sea (1968–1978)
This data paper presents a multi-year database containing information about diets and traits for demersal fish species from the Western Baltic Sea, as well as on resource abundances and environmental conditions. These historical data are unique as they provide detailed descriptions of quantitative and trait-based consumer-resource interactions enabling various ways of innovative food-web analyses.
Flexible foraging behaviour increases predator vulnerability to climate change
Based on a combination of (historical) empirical data and model simulations the authors investigated how size-selective adaptive behaviour under warmer conditions in demersal marine fishes might affect their long-term population stability. Under warmer conditions the fish species studied tend to consume less efficiently by choosing smaller and more abundant prey increasing their extinction risk.
Reviving Europe's rivers: Seven challenges in the implementation of the Nature Restoration Law to restore free-flowing rivers
The authors identified potential challenges and ambiguities in the EU-NRL for restoring free-flowing rivers. They propose clear definitions of critical terms and the development of integrated assessment methods for prioritising actions to improve river connectivity as novel solutions to these challenges, contributing to the success of habitat restoration and biodiversity protection.
Widely used herbicide metolachlor can promote harmful bloom formation by stimulating cyanobacterial growth and driving detrimental effects on their chytrid parasites
The study investigated the effects of the herbicide metolachlor on host-parasite interactions, using the host-parasite system of the toxigenic cyanobacterium Planktothrix agardhii and its chytrid parasite Rhizophydium megarrhizum. Metolachlor promoted cyanobacteria growth and caused multi and transgenerational detrimental effects on parasite fitness. However, these effects are reversible.
What factors influence the rediscovery of lost tetrapod species?
The authors created a database of lost and rediscovered tetrapod species (amphibians, reptiles, birds and mammals), identified patterns in their distribution and factors influencing rediscovery. Tetrapod species are being lost at a faster rate than they are being rediscovered, due to slowing rates of rediscovery for amphibians, birds and mammals, and rapid rates of loss for reptiles
