Environmental flows (e-flows) aim to mitigate the threat of altered hydrological regimes in river systems and connected waterbodies are an important component integrated strategies address multiple threats freshwater biodiversity. Expanding accelerating implementation e-flows can support conservation help restore biodiversity resilience hydrologically water-stressed rivers ecosystems. While there have been significant developments e-flow science, assessment, societal acceptance, within water resource management has slower than required geographically uneven.

ABSTRACT Freshwater biodiversity conservation has received substantial attention in the scientific literature and is finally being recognized policy frameworks such as Global Biodiversity Framework its associated targets for 2030. This important progress. Nonetheless, freshwater species continue to be confronted with high levels of imperilment widespread ecosystem degradation. An Emergency Recovery Plan (ERP) proposed 2020 comprises six measures intended “bend curve” loss, if they are widely adopted adequately supported. We review evidence suggesting that combined intensity persistent emerging threats become so serious current projected efforts preserve, protect restore inland‐water ecosystems may insufficient avert losses coming decades. In particular, climate change, complex harmful impacts, will frustrate attempts prevent from already affected by multiple threats. Interactions among these limit recovery populations exacerbate declines resulting local or even global extinctions, especially low‐viability degraded fragmented ecosystems. addition impediments represented we identify several other areas where absolute scarcity fresh water, inadequate information predictive capacity, a failure mitigate anthropogenic stressors, liable set limits on biodiversity.

Multiple dimensions of extreme weather events and their impacts on biodiversity

Abstract Climate change is a multidimensional phenomenon. As such, no single metric can capture all trajectories of and associated impacts. While numerous metrics exist to measure climate change, they tend focus on central tendencies neglect the multidimensionality extreme weather events (EWEs). EWEs differ in their frequency, duration, intensity, be described for temperature, precipitation, wind speed, while considering different thresholds defining “extremeness.” We review existing EWE outline framework classifying interpreting them light foreseeable impacts biodiversity. Using an example drawn from Caribbean Central America, we show that reflect unequal spatial patterns exposure across region. Based available evidence, discuss how such relate threats biological populations, empirically demonstrating ecologically informed help processes as mangrove recovery. Unveiling complexity affecting biodiversity only possible through mobilisation plethora metrics. The proposed represents step forward over assessments using dimensions or averages highly variable time series.

Unfolding the dynamics of ecosystems undergoing alternating wet‐dry transitional states

Ecology Letters, Год журнала: 2024, Номер 27(8)

Опубликована: Авг. 1, 2024

Abstract A significant fraction of Earth's ecosystems undergoes periodic wet‐dry alternating transitional states. These globally distributed water‐driven ecosystems, such as intermittent rivers and coastal shorelines, have traditionally been studied two distinct entities, whereas they constitute a single, interconnected meta‐ecosystem. This has resulted in poor conceptual empirical understanding ecosystems. Here, we develop framework that places the temporal availability water core driver biodiversity functional patterns at global scale. Biological covers (e.g., aquatic biofilms biocrusts) serve an excellent model system thriving both terrestrial states, where their succession underscores intricate interplay between these The duration, frequency, rate change cycles impose plausible scenarios different types biological can occur depending on desiccation/hydration resistance traits. implies eco‐evolutionary potential covers, represented by trait profiles, would support functions while maintaining similar multifunctionality levels. By embracing multiple states our approach help to better understand manage impacts providing new avenues for interdisciplinary studies.

Climatic effects on the synchrony and stability of temperate headwater invertebrates over four decades

Abstract Important clues about the ecological effects of climate change can arise from understanding influence other Earth‐system processes on ecosystem dynamics but few studies span inter‐decadal timescales required. We, therefore, examined how variation in annual weather patterns associated with North Atlantic Oscillation (NAO) over four decades was linked to synchrony and stability a metacommunity stream invertebrates across multiple, contrasting headwaters central Wales (UK). Prolonged warmer wetter conditions during positive NAO winters appeared synchronize variations population community composition among within streams thereby reducing levels organization. This climatically mediated synchronization occurred all irrespective acid–base status land use, weaker where invertebrate communities were more functionally diverse. Wavelet linear models indicated that explained up 50% overall species abundances at timescale 4–6 years. The affect through local temperature, precipitation discharge, increasing hydrochemical variability sites might have contributed. Our findings illustrate large‐scale climatic fluctuations generated persistence inland freshwater ecosystems ways transcend catchment character. Protecting restoring functional diversity increase their against warmer, are analogues ongoing change. Catchment management could also dampen impacts provide options for adaptation.

A global assessment of environmental and climate influences on wetland macroinvertebrate community structure and function

Global Change Biology, Год журнала: 2024, Номер 30(2)

Abstract Estimating organisms' responses to environmental variables and taxon associations across broad spatial scales is vital for predicting their climate change. Macroinvertebrates play a major role in wetland processes, but studies simultaneously exploring both community structure trait gradients are still lacking. We compiled global dataset (six continents) from 756 depressional wetlands, including the occurrence of 96 macroinvertebrate families, phylogenetic tree, 19 biological traits. Using Bayesian hierarchical joint species distribution models (JSDMs), we estimated compared influences local climatic predictors on individual families While were mainly related broad‐scale factors (maximum temperature precipitation seasonality), traits strongly hydroperiod. Interestingly, showed positive negative same variables. As expected, many family occurrences positively associated with temperature, few opposite pattern found cooler or montane regions. also that communities would likely be affected by changing climates through alterations seasonality, area. Temperature increases may negatively affect collector shredder functional groups. A decrease could lead reductions area benefiting drought‐tolerant macroinvertebrates, it macroinvertebrates lacking those adaptations.
