ABSTRACT Freshwater biodiversity is the fastest declining part of global biota, threatened by multiple stressors including habitat loss and fragmentation, climate change, invasive species, water pollution, abstraction humans. A multitude recent agenda‐setting publications have pointed out key objectives goals for addressing this freshwater crisis, but important gaps must be overcome to reach ambitious conservation targets. In perspective, we complement these high‐level papers in highlighting knowledge, governance, implementation. This gap‐oriented approach designed facilitate meaningful action missing ‘pieces’ process, their connection existing emerging solutions literature. We derive 13 overarching from a conference session informal synthesis literature catalyse research, advocacy, meet post‐2020 Kunming–Montreal Global Biodiversity Framework (GBF). Key include inventory data on biodiversity, collating mobilizing evidence practice, improving coordination ecological governance at scale —including within across catchments—and navigating trade‐offs between economic development, resource consumption, priorities biodiversity. Finally, apply language describing GBF conservation, point which may help address gaps. Major themes that use Nature‐based Solutions Other Effective Area‐based Conservation Measures (OECMs), navigation management human environmental needs, co‐production knowledge with Indigenous local people other stakeholders, integration research aquatic terrestrial ecosystems, funding policy mechanisms support monitoring hydrological scales.

ABSTRACT Drying river networks include non‐perennial reaches that cease to flow or dry, and drying is becoming more prevalent with ongoing climate change. Biodiversity responses have been explored mostly at local scales in a few regions, such as Europe North America, limiting our ability predict future global scenarios of freshwater biodiversity. Locally, acts strong environmental filter selects for species adaptations promoting resistance resilience desiccation, thus reducing aquatic α‐diversity. At the network scale, generates complex mosaics dry wet habitats, shaping metacommunities driven by both dispersal processes. By repeatedly resetting community succession, can enhance β‐diversity space time. To investigate transferability these concepts across continents, we compiled analyzed unique dataset 43 invertebrate from South America. In Europe, α‐diversity was consistently lower than perennial reaches, whereas this pattern not evident Concomitantly, higher ones but general, predominantly turnover rather nestedness. Dispersal main driver metacommunity dynamics, challenging prevailing views science filtering primary process metacommunities. Lastly, decreased duration increased, consistent Europe.

As change intensifies, increasing, results underscore importance studying its effects different The also suggests management efforts should seek connectivity between effectively monitor, restore conserve

Abstract Biological assemblages in streams are influenced by hydrological dynamics, particularly non‐perennial systems. Although there has been increasing attention on how drying impacts stream organisms, few studies have investigated specific characteristics of and subsequent wetting transitions influence biotic responses via resistance resilience traits. Here, we characterized hydrologic metrics, including those quantifying as well dry wet phases, alter diversity composition three aquatic southern California: benthic macroinvertebrates, soft‐bodied algae diatoms. We found that flow duration prior to sampling was correlated with variation macroinvertebrate algal assemblage composition. The richness diatom assemblages, however, were predominantly the start date sampling. Contrary other studies, phase did not or any assemblage. our study conducted within a region which each experienced comparable environmental conditions, no single metric all same way. hot‐summer Mediterranean climate California likely acts strong filter, taxa this relying adaptations survive recolonize following wetting. different metrics suggest greater events, for primary producers. As patterns continue change, understanding biodiversity could inform management actions enhance ecological communities streams. In particular, creation enhancement regimes natural timing phases sustain refuges support community persistence changing environment.
