1. Freshwater ecosystems cover less than 1% of the planet's surface but support up to 10% of known species. Around 25% of freshwater invertebrate species are under threat of extinction. Such a decline in species richness is likely to lead to adverse effects on the delivery of services. However, the effect of species loss on ecosystem goods and services can only be assessed once the link between species diversity and ecosystem goods and services has been established and better understood. 

Conservation of aquatic invertebrates: concerns, challenges and conundrums

Invertebrates inhabiting marine and freshwater ecosystems make important contributions to global biodiversity and provide significant services that have cascading effects across ecosystems. However,

Estimating aquatic invertebrate diversity in the southern Alps using data from Biodiversity Days

High biodiversity is a prerequisite for the integrity, stability, and functioning of global aquatic ecosystems, but it is currently subject to anthropogenic threats. Small freshwater bodies with high

Benthic Insect Assemblage and Species-Level Responses to Eleven Years of Nutrient Addition in the Kootenai River, Idaho

Abstract Because of their abundance and intermediate trophic level positions, benthic invertebrates can affect trophic dynamics in aquatic ecosystems by routing and regulating energy through aquatic


The concept that biodiversity and healthy functioning ecosystems provide goods and services of benefit and value to human wellbeing has been accepted for decades, but it was the Millennium Ecosystem

Nitrogen and phosphorus enrichment cause declines in invertebrate populations: a global meta‐analysis

A meta‐analysis of 1679 cases from 207 studies reporting the effects of N, P, and combined N + P enrichment on the abundance, biomass, and richness of aquatic and terrestrial invertebrates suggests that N and P enrichment affect invertebrate community structure mainly by decreasing inverterestrial abundance.

The Role of Biodiversity in the Functioning of Freshwater and Marine Benthic Ecosystems

Results from these small-scale, low-diversity manipulative studies indicate that the effects of changes in biodiversity are highly variable over space and time and frequently depend on specific biological traits or functional roles of individual species.

The Economic Value of Ecological Services Provided by Insects

The annual value of these ecological services provided by insects to the United States is estimated to be at least $57 billion, an amount that justifies greater investment in the conservation of these services.


Understanding this complexity, while taking strong steps to minimize current losses of species, is necessary for responsible management of Earth's ecosystems and the diverse biota they contain.

Extinction Rates of North American Freshwater Fauna

Abstract: Since 1900, 123 freshwater animal species have been recorded as extinct in North America. Hundreds of additional species of fishes, mollusks, crayfishes, and amphibians are considered

The Role of Benthic Invertebrate Species in Freshwater Ecosystems: Zoobenthic species influence energy flows and nutrient cycling

Examples of how some species have a disproportionately large impact on food-web dynamics and how particular species provide essential ecosystem services are highlighted.

Influence of ecosystem engineers on ecosystem processes is mediated by lake sediment properties

Invasive species may impact biotic community structure, ecosystem processes, and associated goods and services. Their impact may be especially strong when they also serve as ecosystem engineers (i.e.

Freshwater biodiversity: importance, threats, status and conservation challenges

This article explores the special features of freshwater habitats and the biodiversity they support that makes them especially vulnerable to human activities and advocates continuing attempts to check species loss but urges adoption of a compromise position of management for biodiversity conservation, ecosystem functioning and resilience, and human livelihoods.

Biodiversity, functional roles and ecosystem services of groundwater invertebrates

Examples from Australian and New Zealand alluvial aquifers reveal knowledge gaps in understanding the functional importance of most stygofauna, hampering effective protection of currently undervalued groundwater ecosystem services.

Fungicide-induced declines of freshwater biodiversity modify ecosystem functions and services.

A path analysis suggests that chlorothalonil-induced reductions in biodiversity and top-down and bottom-up effects facilitated algal blooms that shifted ecosystem functions.
