A field survey along a food quantity and quality gradient revealed that both host population density as well as prevalence and diversity of epibionts (i.e. organisms living on a host) in the water flea Daphnia pulex are significantly affected by phytoplankton N:P ratio. A laboratory experiment using Daphnia magna confirmed that P‐limitation affects infestation by epibionts.

The deep biodiversity crisis calls for effective targets for its preservation. The authors argue for a “safety net” made up of multiple interlinked and ambitious goals to tackle nature’s alarming decline. No single target captures the broad range of biodiversity components that are dependent on each other. The study outlines the scientific basis for redesigning the new set of biodiversity goals.

This comprehensive study analyses the relationship between urbanization and biodiversity across multiple aquatic and terrestrial animal groups and at multiple spatial scales. The study reveals an overall strong negative impact of urbanization on both abundance and species richness within habitat patches. The study highlights the importance of considering multiple spatial scales and taxa.

Does evolution influence ecological patterns in space? The authors synthesized 500 studies to develop a predictive framework for whether and when evolution amplifies, dampens, or creates ecological patterns. They show that local adaptation can alter spatial variation in population, community and ecosystem features. Dampening of ecological differences is the most prominent effect of evolution.  

This study indicates that nod-gene-targeted long-read sequencing can be a powerful tool for studying the ecology of oxygenic denitrifiers, and the results also suggest that oxygenic these novel microbes are prevalent and abundant in different terrestrial samples, where they could play an important, but yet overlooked role in nitrogen transformations.

Three 1D lake models reproduced the overall impacts of storms and heatwaves well. The timing of effects was simulated accurately. Uncertainty in simulations increased during extremes compared to reference periods. Increased uncertainty should be kept in mind when applying models to extreme events.

A Daphnia-parasite system was used to assess long term effects of fungicide pollution. Parasitic yeast lineages were reared in the absence/presence of tebuconazole (TEB). Multigenerational exposure to TEB caused transient phenotypic costs in the parasite. Parasitic yeast M. bicuspidata showed no potential for rapid evolution to TEB.

The authors reviewed ecological studies in historic canal systems, examined the potential of historic canals to contribute to aquatic biodiversity conservation, and provided suggestions to promote biodiversity conservation given the opportunities and challenges in canal management (e.g., nature conservation vs historic preservation).
