  author={Stuart E. Bunn and Angela H. Arthington},
  journal={Environmental Management},
The flow regime is regarded by many aquatic ecologists to be the key driver of river and floodplain wetland ecosystems. We have focused this literature review around four key principles to highlight the important mechanisms that link hydrology and aquatic biodiversity and to illustrate the consequent impacts of altered flow regimes: Firstly, flow is a major determinant of physical habitat in streams, which in turn is a major determinant of biotic composition; Secondly, aquatic species have… Expand

Environmental and Ecological Effects of Flow Alteration in Surface Water Ecosystems
The alteration of river flow regimes by dams, weirs, and water extraction is a key impact of humans on freshwater ecosystems and has occurred in rivers across all inhabited continents worldwide. InExpand
Mechanistic effects of low-flow hydrology on riverine ecosystems: ecological principles and consequences of alteration
The mechanistic links described in this synthesis can be used to develop and test hypotheses of low-flow hydrological–ecological response relationships in a cause–effect framework that will have value for both research and river flow management. Expand
The impact of river regulation on the biodiversity intactness of floodplain wetlands
Alteration of natural flow regime is considered a major threat to biodiversity in river floodplain ecosystems. Measurements of quantitative relationships between flow regime change and biodiversityExpand
Assessment of River Ecosystems and Environmental Flows: Role of Flow Regimes and Physical Habitat Variables
Globally, rivers are under tremendous anthropogenic stress caused by flow fragmentation, land use changes and regulation. Floodplains had been cut out from rivers by embankments due to urbanExpand
Fish assemblages respond to altered flow regimes via ecological filtering of life history strategies
SUMMARY 1. In riverine ecosystems, streamflow determines the physical template upon which the life history strategies of biota are forged. Human freshwater needs and activities have resulted inExpand
River fisheries: ecological basis for management and conservation
Large rivers and their floodplains support a significant proportion of the world's biodiversity and provide important goods and ecological services to society, including fisheries. RiverineExpand
The influence of antecedent floods on aquatic invertebrate diversity, abundance and community composition
Anthropogenic alterations to flow regimes have been identified as a serious threat to river ecology. Such alterations can affect the magnitude and timing of high and low flows. It is thereforeExpand
Avian Community Responses to Variability in River Hydrology
River flow is a major driver of morphological structure and community dynamics in riverine-floodplain ecosystems. Flow influences in-stream communities through changes in water velocity, depth,Expand
Integrative freshwater ecology and biodiversity conservation
Abstract Freshwater ecosystems provide goods and services of critical importance to human societies, yet they are among the most heavily altered ecosystems with an overproportional loss ofExpand
Fish assemblages in subtropical rivers: low-flow hydrology dominates hydro-ecological relationships
Abstract Effective environmental flow management depends on identification of ecologically-relevant flow attributes to maintain or restore flows in the context of other natural and human influencesExpand


Ecological connectivity in alluvial river ecosystems and its disruption by flow regulation
The dynamic nature of alluvial floodplain rivers is a function of flow and sediment regimes interacting with the physiographic features and vegetation cover of the landscape. During seasonalExpand
Legitimizing Fluvial Ecosystems as Users of Water: An Overview
It is suggested that fluvial ecosystems are legitimate users of water and that there are basic ecological principles guiding the maintenance of long-term ecological vitality, and basic principles for maintaining the vitality of fluvials ecosystems are presented. Expand
Basic Principles and Ecological Consequences of Changing Water Regimes: Riparian Plant Communities
The basic principles proposed are: the flow regime determines the successional evolution of riparian plant communities and ecological processes, and the riparian corridor serves as a pathway for redistribution of organic and inorganic material that influences plant communities along rivers. Expand
Biodiversity of floodplain river ecosystems: ecotones and connectivity1
A high level of spatio-temporal heterogeneity makes riverine floodplains among the most species-rich environments known. Fluvial dynamics from flooding play a major role in maintaining a diversity ofExpand
The Role of Disturbance in Stream Ecology
We define disturbance in stream ecosystems to be: any relatively discrete event in time that is characterized by a frequency, intensity, and severity outside a predictable range, and that disruptsExpand
Need for Ecosystem Management of Large Rivers and Their Floodplains These phenomenally productive ecosystems produce fish and wildlife and preserve species
The history of floodplain and flood plain management is described and the importance of large river-floodplain ecosystems and some of the consequences of altering the natural river processes, functions, and connectivity are focused on. Expand

The results demonstrate the lotic-to-lentic succession of floodplain ecosystems to be a series of non-sequential reproductive zones, with spawning conditions being reflected by the specific composition and guild structure of the YOY fish assemblages. Expand
The role of sexual reproduction and water regime in shaping the distribution patterns of clonal emergent aquatic plants
The reproductive characteristics of T. procerum in three lagoons in the Mediterranean south-east of South Australia were used to investigate the role of water regime in the often heterogeneous andExpand
Distribution, productivity and reproductive phenology of emergent macrophytes in relation to water regimes at wetlands of south-western Australia
Variability in the response of Baumea articulata and Typha orientalis to water regime was assessed at eight urban wetland lakes on the Swan Coastal Plain, south-western Australia. Distribution,Expand
Structure and ecological production of the fish taxocene of a small floodplain system
Number of days of stream connection in the spring was not significantly correlated with fish species richness in the pools, and a significant correlation was found between species richness and the logarithm of pool area. Expand
