Variations in benthic macroinvertebratefauna as indicator of land use in the Ken River, central India

Journal of Threatened Taxa, 2013
Examination of benthic macroinvertebrates in semi-natural, urban and agricultural land use along the highland Ken River in central India reveals a significantly higher density in semi-natural compared with other two landuse. Insects dominate the fauna at

Ecological Integrity Impairment and Habitat Fragmentation for Neotropical Macroinvertebrate Communities in an Agricultural Stream

Toxics, 2022
The Volcán River watershed in the south Pacific of Costa Rica comprises forests, small urban settlements, cattle fields, and intensive agriculture (mostly pineapple and sugarcane). The ecological integrity and quality of its waters was assessed from 2011–

Upstream Deforestation and Nonnative Crops Affect Leaf Breakdown and Aquatic Invertebrate Assemblages in Streams

Freshwater Biology, Volume 70, Issue 10, October 2025.
ABSTRACT Stream ecosystem functioning and community structure are influenced by local and catchment land use. In mosaic landscapes, agricultural activities can also affect leaf breakdown and detritivore assemblages in downstream forest reaches. We evaluated the combined effects of upstream deforestation and the input of a nonnative crop species on leaf

Short‐term forest harvesting effects on emergence rates of aquatic insects from small streams treated with different riparian management

Journal of Applied Ecology, Volume 62, Issue 9, Page 2398-2408, September 2025.
These results highlight the detrimental impact of harvesting along stream ecosystems where riparian buffer width is insufficient and demonstrate that a 30‐m buffer may offer substantial protection, strengthening the scientific foundation for sustainable riparian forest management.

Impact of riparian land-use patterns on Ephemeroptera community structure in river basins of the southern Western Ghats, India

Knowledge and Management of Aquatic Ecosystems, 2014
This study analysed the impact of riparian land use in structuring the larval ephemeropteran communities from 25 sites in streams and rivers of Kalakad-Mundanthurai Tiger Reserve (KMTR) of the southern end of the Western Ghats, India.

Investigating the Effects of Flow Regulation Combining Stream Geomorphology With Macroinvertebrate Ecology: A Case Study in the Orobic Alps (Italy)

Ecohydrology, Volume 18, Issue 5, July‐August 2025.
ABSTRACT Mountain streams exhibit hydrogeomorphological heterogeneity, which is further intensified by the presence of hydraulic infrastructure. Despite extensive research on the influence of hydrological conditions and flow regulation on ecology, there is a notable absence of holistic studies investigating stream dynamics from both geomorphologic and ...

An unexpected record of Simothraulopsis Demoulin, 1966 (Ephemeroptera, Leptophlebiidae) in the Paraná Basin, Brazil [PDF]

Check List, 2019
We recorded for the first time the occurrence of the mayfly genus Simothraulopsis Demoulin, 1966 in the Paraná Basin. Adults of Simothraulopsis demerara (Traver, 1947) and Simothraulopsis diamantinensis Mariano, 2010 were collected using a ...
