ClearOccurrence Of Microplastics in Immature Aquatic Insects of Gua Musang Tributaries in Kelantan
Researchers investigated the presence and abundance of microplastics in freshwater immature aquatic insects, specifically caddisfly (Trichoptera) and dragonfly (Odonata) larvae, collected from two tributaries of Gua Musang in Kelantan, Malaysia. The study found that microplastics had accumulated in these larvae, raising concerns about microplastic transfer through aquatic food chains in the region.
Aquatic insects as mediator for microplastics pollution in a river ecosystem of Bangladesh
Researchers found that aquatic insects in a Malaysian river ecosystem ingest microplastics and can transport them across ecosystem boundaries as the insects emerge from water to land, functioning as biological vectors that move plastic contamination from aquatic to terrestrial food webs.
Occurrence and physical characterization of microplastics in mangrove-dwelling Fireflies (Coleoptera: Lampyridae) of entotourism importance
Researchers examined microplastic contamination in mangrove-dwelling fireflies in Malaysia, finding microplastics in 50% of larvae and 14.8% of adults, representing one of the first studies of microplastic occurrence in this ecologically and culturally important insect group.
Response of Odonata assemblages to disturbance in urban freshwater habitats
This paper is not about microplastics — it investigates how Odonata (dragonfly and damselfly) assemblages respond to different levels of habitat disturbance caused by urbanization in freshwater habitats in Ghana.
Using aquatic insects as indicators of microplastic pollution in rice field ecosystems
Researchers used aquatic insect communities as bioindicators of microplastic pollution in rice field ecosystems, comparing insect diversity and abundance across fields with different levels of plastic contamination. Insect assemblages responded sensitively to microplastic loads, demonstrating their potential as low-cost monitoring tools.
Relative contributions of different local sources to riverborne microplastic in a mixed landuse area within a tropical catchment
Researchers quantified the relative contributions of different land-use sources to riverborne microplastics in a tropical catchment, providing data to help prioritize pollution reduction measures for protecting human and ecological health.
Effects of anthropogenic activities on microplastics in deposit-feeders (Diptera: Chironomidae) in an urban river of Taiwan
Researchers quantified microplastic abundance and types in midge larvae (Chironomidae) from an urban river and found that multiple anthropogenic activities including industrial discharge, agriculture, and residential runoff were associated with elevated microplastic levels in these freshwater deposit-feeders.
Freshwater insects of different feeding guilds ingest microplastics in two Gulf of Guinea tributaries in Nigeria
Scientists collected freshwater insects from two Nigerian tributaries of the Gulf of Guinea and found microplastics ingested across different feeding guilds, providing rare baseline data on microplastic contamination of African freshwater ecosystems.
Long-term trends in stream benthic macroinvertebrate communities are driven by chemicals
This paper is not about microplastics. It investigates long-term trends in stream macroinvertebrate communities in Germany from 2007 to 2021, finding that in-stream chemical pollution data explained about 50% of the variation in biodiversity changes over time. The study focuses on freshwater ecology and the effects of water chemistry, land use, and temperature on aquatic invertebrate diversity, with no specific focus on microplastic contamination.
Synergistic Impact of Complex Topography and Climate Variability on the Loss of Microclimate Heterogeneity in Southeast Asia
Not relevant to microplastics — this paper analyzes how topography and climate variability have driven declining microclimate heterogeneity in Southeast Asia between 1982 and 2017, with implications for regional biodiversity.
The revelry of plastic! Quali-quantitative variation of microplastics in freshwater before and after Carnival in south-eastern Brazil
Researchers conducted a quali-quantitative survey of microplastics in freshwater habitats, characterizing variation in abundance, polymer type, and morphology across multiple sites and linking pollution levels to upstream land use and human activity.
The fate and ecological consequences of microplastics in non-perennial streams
This review examines the fate and ecological consequences of microplastics in non-perennial (intermittent) streams, which represent the majority of waterways globally yet have been largely overlooked in microplastic research. The authors identify key knowledge gaps around how alternating wet and dry phases affect microplastic transport, fragmentation, and accumulation, as well as impacts on organism communities in these ecosystems.
The need of ecohydrological research in tropical forests for healthy watersheds
This paper is not relevant to microplastics; it argues for more ecohydrological research in tropical forests to understand water cycling and watershed health.
Microplastics in freshwater sediments: Effects on benthic invertebrate communities and ecosystem functioning assessed in artificial streams
Researchers tested the effects of polyethylene microplastics on freshwater invertebrate communities in artificial streams using environmentally relevant concentrations. They found that microplastics significantly reduced the abundance of deposit-feeding and grazing organisms by 31-50%, with chironomids and mayflies showing the highest ingestion of plastic particles.
Seasonality can override the effects of anthropogenic activities on microplastic presence in invertebrate deposit feeders in an urban river system
Researchers investigated how anthropogenic land use and seasonality influence internal microplastic concentrations in midge larvae across an urban river watershed in Taiwan, finding that seasonality overrode land-use effects and that agricultural activity had a significant negative nonlinear relationship with microplastic accumulation.
Do microplastics and climate change negatively affect shredder invertebrates from an amazon stream? An ecosystem functioning perspective
Researchers experimentally tested the combined effects of microplastic pollution and climate change conditions on the survival and feeding behavior of an Amazonian freshwater shredder invertebrate. The study suggests that the combination of microplastic exposure with increased temperature and CO2 levels can negatively affect these organisms, with implications for leaf litter decomposition and ecosystem functioning in tropical streams.
The Role of Landscape Configuration, Season, and Distance from Contaminant Sources on the Degradation of Stream Water Quality in Urban Catchments
A study of a Portuguese river basin found that landscape configuration and proximity to pollution point sources both affect stream macroinvertebrate communities. Macroinvertebrates are sensitive to microplastic pollution, and their decline in contaminated streams can indicate broader ecosystem degradation.
Ecological traits do not predict the uptake of microplastics by fishes in a Neotropical River
Researchers found that ecological traits such as feeding guild, habitat use, and body size do not reliably predict microplastic uptake in fish species from a Neotropical river, suggesting contamination patterns are driven more by local environmental conditions than by species-specific biology.
Microplastic loads within riverine fishes and macroinvertebrates are not predictable from ecological or morphological characteristics
Researchers measured microplastic loads in riverine fish and macroinvertebrates and found that particle counts were not reliably predicted by species ecology or morphology, suggesting that individual variation and local environmental factors play a larger role in microplastic ingestion than feeding guild or habitat alone.
Glitter ingestion by bromeliad-dwelling macroinvertebrates: implications for freshwater microplastic contamination
Researchers exposed macroinvertebrates living in bromeliad leaf reservoirs to glitter particles as a microplastic proxy, finding ingestion occurred across multiple taxa and that glitter persisted in the gut and environment longer than natural food particles.
Soil Physico-chemical Properties in a Selectively Logged Forest at Gunung Rara Forest Reserve, Sabah, Malaysia
This paper is not relevant to microplastics research — it examines how different logging methods (supervised versus conventional) affect soil physical and chemical properties in a tropical rainforest reserve in Malaysia.
