The Spatial Discrepancy Between Colombian Freshwater Fish Suitable Habitats and Existing Protected Areas
The study shows: Only 25 per cent of newly-delineated priority areas identified for the protection of freshwater fishes in Colombia overlap with existing protected areas. Strikingly, the required amount of area is similar to that of the existing protected areas. However, a more efficient spatial distribution would be important.
A collaborative research agenda for restoring free-flowing rivers
The Nature Restoration Regulation (NRR) calls for restoring at least 25,000 kilometres of free-flowing rivers by 2030. Translating this ambition into implementation remains challenging due to differing restoration priorities across ecological, social, economic and governance contexts. This study offers a roadmap to support the implementation of the NRR's goal of restoring free-flowing rivers.
Global assessment of alien freshwater megafauna reveals complex socio-economic impacts
This study shows: Over 40 percent of extant large freshwater animals (megafauna) have been deliberately introduced outside their natural ranges, often for economic gain. While these alien species can provide substantial benefits to certain groups in the introduced regions, they also posed profound and often underestimated risks to native biodiversity and local people.
Distinct contributions of suspended and sinking prokaryotes to mesopelagic carbon budget
Oceans are important carbon sinks. Bacteria play a central role in carbon cycling because, collectively, they convert more organic material than all other marine organisms combined. Their activity acts as a “carbon pump”, ensuring that life is possible in the deep sea. The authors quantified the effect of bacteria in the middle ocean layers, known as the twilight zone, in the North-East Atlantic.
Flow variability and macroinvertebrates jointly regulate stream periphyton and metabolism: Insights from experimental stream mesocosms
In stream mesocosm experiments the authors tested how reduced flow and a sequence of controlled flushing events, with or without macroinvertebrates, affect periphyton community composition, algal biovolume, and ecosystem metabolism. Flow variability and macroinvertebrates control periphyton structure, metabolism, and carbon cycling, with macroinvertebrates stabilising responses to disturbance.
Effects of Biodiversity Loss on Freshwater Ecosystem Functions Increase With the Number of Stressors
Challenges in studying microplastics in human brain
Microplastics are ubiquitous – in the environment and in the human body. However, accurately detecting these particles poses major challenges for researchers from various disciplines. The authors described the methodological difficulties in the journal and call for more standardized methods in biomonitoring.
A roadmap for equitable reuse of public microbiome data
Science benefits from the rapid and open exchange of knowledge. However, there is a lack of appropriate community standards for data exchange between different institutions. In this article the authors discuss improvements for the exchange of extensive microbiome data.
