Ecological Impacts of Altered Stream Hydrogeomorphic Characteristics Extend Beyond the Channel Boundary: Evidence From Urban Streams of Columbus, OH, United States

open access: yesFrontiers in Ecology and Evolution, 2022
Urbanization in stream catchments can have strong effects on stream channel hydrogeomorphic features including channel dimensions, channel-floodplain connectivity, and flood regime.

Diel variation of aquatic insect drift in streams of Southern Brazil

open access: yesActa Scientiarum: Biological Sciences, 2021
Some organisms, such as aquatic insects, are transported from the upstream to downstream region of streams through a process called drift. This process occurs in passive and active ways and can be variable throughout the day, mainly between the ...

Aquatic Insects Are Dramatically Underrepresented in Genomic Research

open access: yesInsects, 2020
Aquatic insects comprise 10% of all insect diversity, can be found on every continent except Antarctica, and are key components of freshwater ecosystems. However, aquatic insect genome biology lags dramatically behind that of terrestrial insects.

The Relationship Between Grazing, Er osion and Adult Aquatic Insects in Streams in Mongolia. [PDF]

open access: yesMongolian Journal of Biological Sciences, 2010
Overgrazing along stream channels in Mongolia may impact streams by increasing stream channel erosion and in-stream sediments, water temperature, pH, and conductivity. Grazing and erosion impacts may impair stream insects.

Species-specific biomagnification and habitat-dependent trophic transfer of halogenated organic pollutants in insect-dominated food webs from an e-waste recycling site

open access: yesEnvironment International, 2020
Aquatic, amphibious, and terrestrial organisms in or around a pond that was contaminated by e-waste were collected and persistent halogenated organic pollutants (HOPs) for these species were analyzed.

Ultrastructural and molecular approach as a tool for taxonomic identification of aquatic macroinvertebrates: A review

open access: yesHeliyon, 2022
Aquatic insects require water at one or other phase for the completion of their life cycle. The insect larvae serve as food for larger invertebrates and vertebrates in aquatic food chain.

Aquatic insects differentially affect lake sturgeon larval phenotypes and egg surface microbial communities

open access: yesPLoS ONE, 2022
Documentation of how interactions among members of different stream communities [e.g., microbial communities and aquatic insect taxa exhibiting different feeding strategies (FS)] collectively influence the growth, survival, and recruitment of stream ...

Assessing the role of canopy cover on the colonization of phytotelmata by aquatic invertebrates: an experiment with the tank-bromeliad Aechmea lingulata

open access: yesJournal of Limnology, 2016
The presence of canopy cover may influence the amount of organic detritus and stored water in bromeliad tanks and, consequently, the colonization of these ecosystems by aquatic invertebrates.
