No post-drought recovery of the macroinvertebrate community after five months upon rewetting of an irregularly intermittent Apennine River (Aterno River)

Antonio Di Sabatino et al.

Summary: The combined effects of global changes and increasing water demand are causing watercourses to become more intermittent, with significant impacts on freshwater biota and ecosystem processes. This study investigated the recovery dynamics of benthic invertebrates after a drought period of five months. The findings showed that recolonization was limited and partial, resulting in lower richness and abundance compared to the pre-drought community. The observed recolonization pattern was mainly influenced by aerial dispersal from downstream perennial areas. These findings highlight the drastic changes in community structure and composition caused by increasing intermittence, with negative effects on key ecosystem processes.

Dynamics of streamflow permanence in a headwater network: Insights from catchment-scale model simulations

D. T. Mahoney et al.

Summary: This study expanded the understanding of streamflow permanence in headwater systems by developing a process-based, catchment-scale hydrologic model that identified the controls of streamflow expansion and contraction in a headwater network. The model simulated that streamflow permanence was highly dynamic in first-order reaches, with the simulated stream network length ranging from nearly 98% ± 2% of the geomorphic channel extent during wet periods to nearly 50% ± 10% during dry periods. The study also revealed a discharge threshold above which the rate of streamflow expansion decreased significantly during high-flow periods.

A global transition to flash droughts under climate change

Xing Yuan et al.

Summary: Flash droughts have become increasingly common worldwide, posing challenges to drought monitoring and prediction. The intensification of droughts has accelerated over subseasonal time scales, leading to a transition towards more flash droughts in 74% of global regions over the past 64 years. This transition is linked to amplified anomalies in evapotranspiration and precipitation deficit due to human-induced climate change. In the future, this transition is expected to expand to most land areas, with greater increases under higher-emission scenarios. These findings highlight the urgency of adapting to faster-onset droughts in a warmer future.

Increasing heatwave frequency in streams and rivers of the United States

Spencer J. Tassone et al.

Summary: The frequency of heatwaves in rivers has been increasing in the United States, particularly in summer and fall, in mid- to high-order streams, and at free-flowing sites and sites above a reservoir. This increase in frequency is accompanied by an increase in moderate strength heatwaves and a doubling of the annual mean total number of heatwave days at a site. These heatwaves are often associated with normal or below-normal discharge conditions and occur at sites with lower mean annual discharge.

Summary: Intermittent rivers are the predominant type of running waters on Earth, and human-induced flow intermittence (AFI) has unique hydrological and biological impacts. This review examines the causes and alterations of drying in AFI compared to natural flow intermittence (NFI), evaluates the differences in biodiversity responses, ecological functions, and ecosystem services between the two, and highlights knowledge gaps and management needs related to AFI.

This study presents a comprehensive framework for understanding the hydrology of these pools, including the key hydraulic mechanisms that control their persistence. Throughflow of alluvial water and groundwater discharge are identified as the main mechanisms, and various diagnostic tools are summarized and critiqued for their application in studying these hydraulic processes. The framework allows for assessing the vulnerability of river pools to climate change and groundwater extraction.

A meta-system approach is proposed to integrate these processes into river conservation, restoration, and biomonitoring, with the implementation of relevant measurements and indicators. Alternative management strategies are needed to guide practitioners in applying recent advances in ecology to preserve and restore river ecosystems in the face of increasing alteration of river network connectivity worldwide.

Local hydrological conditions and spatial connectivity shape invertebrate communities after rewetting in temporary rivers

David Pineda-Morante et al.

Summary: This study investigates the formation of invertebrate communities in temporarily rivers after rewetting and finds that both hydrological conditions and spatial connectivity play important roles. The frequency and duration of drying events decrease taxonomic and functional richness, while time since the most recent rewetting increases these metrics. Network connectivity shows a significant unimodal relationship with taxonomic and functional metrics, while the presence of nearby disconnected streams is negatively related to functional richness and functional dispersion.

This paper reviews the current literature on IRES invertebrates and presents conceptual models to understand their response to hydrological changes. The models are tested using data from wet and dry phases in IRES from Australia and France.

An eight-year experiment in southeastern Australia showed that aquatic invertebrates did not significantly respond to riparian restoration, possibly due to severe drought conditions.

Mapping dynamic non-perennial stream networks using high-resolution distributed hydrologic simulation: A case study in the upper blue river basin

The results show that the CREST model can accurately capture low to moderate streamflow values at the watershed outlet and estimate wet/dry status in small headwater tributaries, while underestimating high flow values. The mapping of dynamic stream networks using the CREST simulation reveals that non-perennial streams are the most dynamic in small headwater tributaries and high-order streams are sustained by perennial flow, showcasing the potential of using distributed hydrologic models for mapping dynamic streams globally.
