Colonisation of leaf litter by aquatic invertebrates in an Atlantic Forest stream

open access: yesBrazilian Journal of Biology
Riparian vegetation along streams in the Atlantic Forest in Brazil contributes to the formation of a highly heterogeneous leaf litter in streambeds. To investigate the structure and composition of the aquatic invertebrate community during the process of ...

Restoration using flow deflectors: a question of fine‐scale spatial layout in headwater stream beds

open access: yesRestoration Ecology, Volume 33, Issue 7, September 2025.
Current European Union objectives for 2030 aim to restore ecosystems to halt biodiversity loss. Here, we studied the consequences of headwater stream restoration by placing large wood in the streambed to act as flow deflectors. We hypothesized that these flow deflectors would create a fine‐scale spatial arrangement of habitats, fostering a diverse and ...

Breakdown of Leaf Litter in a Neotropical Stream [PDF]

open access: yes, 2002
We investigated the breakdown of 2 leaf species, Croton gossypifolius (Euphorbiaceae) and Clidemia sp. (Melastomataceae), in a 4th-order neotropical stream (Andean Mountains, southwestern Colombia) using leaf bags over a 6-wk period.

Ecological pathways connecting riverine drought to community change across space and time

open access: yesEcological Monographs, Volume 95, Issue 3, August 2025.
Abstract Climate change is intensifying droughts via reduced snowpack and accelerated snowmelt in high mountains globally, altering community structure in snow‐dependent rivers. To predict impending ecological change in rivers, we must understand the importance of the abiotic and biotic mechanisms connecting hydrologic change to biodiversity change and

Seasonal changes in the feeding habit of Isfahan Chub (Petroleuciscus esfahani) and Brond Snout (Chondrostoma regium) in Zayandehroud River [PDF]

open access: yesبوم‌شناسی آبزیان
In this study, seasonal changes in the diet of Petroleuciscus esfahani and Chondrostoma regium were investigated by collecting 200 samples of each species seasonally in 2013 from the Zayanndehroud River.

The ecology of chalk-stream invertebrates studied in a recirculating stream [PDF]

open access: yes, 1984
To study and qualify the factors influencing interactions between various trophic levels in natural hard-water streams, a recirculating artificial stream channel was constructed. This structure has enabled patterns of population change of stream fauna to

Marine heatwaves amplify benthic community metabolism and solute flux in a seafloor heating experiment

open access: yesFunctional Ecology, Volume 39, Issue 8, Page 1856-1868, August 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The magnitude and frequency of marine heatwaves are increasing and predicted to intensify, but our ability to understand the real‐world effects on vital benthic ecosystems is lagging behind.
