Variations on a Theme: The Classification of Benthic Macroinvertebrates.

, 2012
Vain murto-osa maailman vesivarannoista on makeaa vettä. Jokapäiväisessä ympäristössämme olevat vesistöt, kuten joet, purot, lammet ja järvet ovat vain osajoukko makean veden kokonaismäärästä. Vesistöt kohtaavat nykyään enenevässä määrin erilaisia ympäristöpaineita muun muassa kemikaalipäästöjen muodossa.

Temporal community change in stream ecosystems varies by assemblage across US climates

Functional Ecology, Volume 40, Issue 9, Page 2737-2750, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem properties are temporally dynamic. Temporal variability has been shown to decrease with increasing levels of biological organization (i.e. from population to community and ecosystem levels).

Utilization of both benthic macroinvertebrates and physicochemical

, 2007
This study examines the applicability of five European biotic indices and the Gammarus:Asellus ratio (G:A), compared with the measurement of physicochemical parameters, in order to determine the water quality at ten sites along the Tokat part of Cekerek stream, in Anatolia, Turkey during the period February 2002 to January 2003.

Not Cryptogenic: Molecular and Historical Evidence Supports Introduction of Asparagopsis taxiformis (Rhodophyta) Into the Galápagos Islands

Diversity and Distributions, Volume 32, Issue 9, September 2026.
ABSTRACT Aim Identifying the origins of widespread species is crucial for conservation in isolated biodiversity hotspots, where ‘cryptogenic’ status often hinders effective biosecurity. We investigated the genetic identity and introduction history of the red macroalga Asparagopsis taxiformis in the Galápagos Islands to resolve its cryptogenic status ...

Global Patterns, Drivers and Conservation Gaps of Freshwater Crabs: From Species Richness to Phylogenetic Diversity

Diversity and Distributions, Volume 32, Issue 9, September 2026.
ABSTRACT Aim Freshwater crabs are ecologically vital benthic macroinvertebrates that sustain freshwater ecosystem functions, yet their limited dispersal and fragmented habitats make them vulnerable to human disturbance. Current conservation assessments for freshwater crabs remain incomplete, as most studies focus on species richness while neglecting ...

Macroinvertebrate Prey Availability and Fish Diet Selectivity in Relation to Environmental Variables in Natural and Restoring North San Francisco Bay Tidal Marsh Channels

San Francisco Estuary and Watershed Science, 2014
Tidal marsh wetlands provide important foraging habitat for a variety of estuarine fishes. Prey organisms include benthic–epibenthic macroinvertebrates, neustonic arthropods, and zooplankton.

Are Species Distribution Models That Use Climate Variables Suitable to Forecast the Changing Distribution of Freshwater Organisms?

Freshwater Biology, Volume 71, Issue 9, September 2026.
ABSTRACT Species distribution models can be used to identify locations with environmental conditions suitable for populations in the past, present and future. However, climate variables commonly applied in species distribution models may be unsuitable for freshwater species because their explanatory power is difficult to assess.

Functional traits drive the inter-annual differences in the diversity of benthic macroinvertebrate communities associated with agricultural ditches

Journal of Freshwater Ecology
Ditches are a key feature of the agricultural landscape, especially in relation to rice cultivation. Despite being affected by anthropogenic pressures in terms of flow regulation and channelisation, they can play an important role as habitats for aquatic
