Environmental Toxicology and Chemistry, 2021 There are currently few suitable test systems for the chronic toxicity testing of aquatic macroinvertebrates under stream conditions. Therefore, a new test system mimicking running water conditions was developed for testing with lotic insects.

Effects of herbicides and fertilization on biofilms of Pampean lotic systems: A microcosm study
Science of The Total Environment, 2023We experimentally assessed the impact of the application of herbicides and fertilizers derived from agricultural activity through the individual and simultaneous addition of glyphosate, atrazine, and nutrients (nitrogen 'N' and phosphorus 'P') on the biofilm community and their resilience when the experimental factors were removed.

Freshwater Biology, 2000 1. The spatial and temporal dynamics of lotic meiofaunal communities were examined with a focus on colonisation, maintenance of populations in lotic environments and persistence of meiofaunal communities.2.

Longitudinal dynamics of Odonata assemblages in an anthropogenically impacted lotic system
International Journal of Limnology, 2022European lowland rivers are extensively impacted by hydromorphological pressures, and the relationship between individual benthic macroinvertebrate groups and these degradations are insufficiently investigated. Therefore, we studied distribution and ecological traits of Odonata inhabiting a lotic system in the Pannonian lowland ecoregion (ER 11) in ...

Diatom colonization dynamics in a lotic system
Hydrobiologia, 1986A series of three overlapping sets of slides were exposed in riffle and pool habitats in a fourth order river in the Upper Peninsula of Michigan. Each set was exposed for 6–8 weeks and overlapped the preceeding set by 2 weeks. Diatom cell densities and community structure were determined after daily or weekly exposure periods for each set.

Selenium accumulation patterns in lotic and lentic aquatic systems
Science of The Total Environment, 2006Selenium (Se) concentrations in water column, sediment and insect compartments were measured over 3 years, in conjunction with selected physicochemical parameters, from lotic (flowing water) and lentic (standing water) sites within a single watershed in Utah, USA. There was evidence for steady-state concentrations of total [Se] in the insects, sediment

Patch Dynamics in Lotic Systems: The Stream as a Mosaic
Journal of the North American Benthological Society, 1988This paper applies concepts of landscape ecology and patch dynamics to lotic systems. We present a framework for the investigation of pattern and process in lotic ecosystems that considers how specific patch characteristics determine biotic and abiotic processes over various scales.

A Benthic Chamber for Intensely Metabolic Lotic Systems
Estuaries, 1979We have designed a flow-through benthic chamber that has the desirable characteristics of: simulation of tidal currents, continuous operation, ability to measure photosynthesis, respiration and nutrient exchanges, and maintenance of near-ambient oxygen conditions in a highly metabolic environment. The apparatus is based on a 1.3 m long Plexiglas tunnel,

The invertebrate fauna of four macrophytes in a lotic system
Freshwater Biology, 1984SUMMARY. 1. Invertebrates associated with four species of aquatic plants and on the adjacent substrate were investigated in a riffle/run section of a hard‐water stream.2. Invertebrates were more numerous on stones than on any species of plant (> 17,000m−2 versus 1000–4000 m−2).

Winterkill in Lotic Systems May Be an Important Driver of Amphibian Population Declines
Ichthyology & Herpetology, 2022Studies of frogs overwintering in ice-covered ponds and lakes have documented large winterkills, suggesting that winter can be a time of great stress and may be a serious threat to rare and endangered frog species that overwinter in these systems. Lotic systems are assumed to be better oxygenated and therefore less subject to overwinter mortality than ...
