RNA interference is a widely applicable, powerful technique for manipulating gene expression at specific developmental stages. Here, we describe the necessary steps for implementing this technique in the aquatic diving beetle Thermonectus marmoratus, from the acquisition of gene sequences to the knockdown of genes that affect structure or behavior.

Source: Laboratories of Margaret Workman and Kimberly Frye - Depaul University Nitrogen and phosphorus are essential plant nutrients found in aquatic ecosystems and both are monitored as a part of water quality testing because in excess amounts they can cause significant water quality problems. Nitrogen in water is measured as the common form nitrate (NO3-) that is dissolved in water and readily absorbed by photosynthesizers such as algae. The common form of phosphorus measured is phosphate...

Flow cytometry in combination with visual clustering offers an easy-to-use and fast method for studying aquatic biofilms. It can be used for biofilm characterization, detection of changes in biofilm community structure, and detection of abiotic particles embedded in the biofilm.
FAQs
Aquatic beetles often carry air trapped beneath their bodies or wing covers. They use this stored supply while submerged and return to the surface to replenish it. This strategy allows them to remain underwater while diving, swimming, or moving through submerged vegetation and sediments, linking respiratory access to activity below the water surface.
Body shape and leg structure help aquatic beetles move effectively through their surroundings. Streamlined forms support swimming and diving, while modified legs assist movement through water, sediments, and vegetation. These features help different species exploit particular freshwater habitats, including open water, vegetated areas, stream environments, and the substrate.
Larvae and adults may consume algae, detritus, insects, or small aquatic animals, placing aquatic beetles at different points within aquatic food webs. Their feeding connects organic matter and smaller organisms with beetle populations, while also contributing to broader ecosystem function. The available food therefore helps shape their ecological role within a habitat.
Water quality, habitat structure, and pollution are important conditions associated with aquatic beetle communities. Changes in these factors can influence which species occur and how abundant they become. Because beetles occupy ponds, streams, wetlands, and temporary pools, community patterns may also reflect differences in the physical structure and condition of those habitats.
Aquatic beetles can serve as biological indicators because their abundance and diversity respond to water quality, habitat structure, and pollution. Researchers can examine changes in their communities to assess environmental conditions and support biodiversity studies. Their responses provide ecological information that complements direct consideration of the aquatic habitat itself.
Comparing communities from ponds, streams, wetlands, and temporary pools can show how beetle diversity and abundance vary with habitat conditions. These comparisons help connect community patterns with water quality, pollution, and habitat structure. They also contribute to biodiversity research and clarify how aquatic beetles participate in food webs and ecosystem function.
