We developed a new gadget for epilithic microalgae sampling (GEMS) in rivers. This device enables in situ sampling from natural substrates, improving ecological assessments in lotic environments.

Area of Science:

Aquatic Ecology
Benthic Ecology
Phycology

Background:

Benthic microalgae sampling in lotic systems often uses artificial or natural substrates.
Natural substrates are preferred for accurate biomass, productivity, and biodiversity assessments as they harbor representative communities.

Purpose of the Study:

To introduce a novel gadget for epilithic microalgae sampling (GEMS).
To enable in situ sampling from natural substrates in lotic environments, especially when substrate removal is not feasible.

Main Methods:

The gadget (GEMS) is an acrylic box with a 25 cm diameter opening at the base.
It is designed for use in shallow bedrock streams, isolating the sampling area to minimize contamination and sample loss.

Main Results:
