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

Brazilian 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 ...

Delineating Diversity‐Based Freshwater Bioregions by Integrating Fish and Macroinvertebrates With Species Distribution Models and Spatial Clustering

Ecology and Evolution, Volume 15, Issue 12, December 2025.
We integrated fish and macroinvertebrate data with species distribution models and spatial clustering to delineate coherent freshwater bioregions. The resulting bioregions captured complementary biodiversity patterns and key transition zones more effectively than single‐taxon or UPGMA clustering.

Evaluación de la calidad de las aguas del estero Limache (Chile central), mediante bioindicadores y bioensayos Water quality assessment in the Limache stream (central Chile), using bioindicators and bioassays

Latin American Journal of Aquatic Research, 2009
Se evaluó la calidad de las aguas del estero Limache en cinco estaciones de muestreo en el período de bajo caudal. En cada estación se colectaron macroinvertebrados acuáticos, se midió in situ pH, conductividad, oxígeno disuelto, y sólidos disueltos ...

Assessing the Relationship Between Macroinvertebrate Metrics and Fine Sediment Index for Ecological Biomonitoring in the Little Akaki River, Addis Ababa, Ethiopia

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Habitat quality had a positive correlation with percentage of Ephemeroptera, percentage of EOT, and Shannon diversity index (r = 0.833, r = 0.880, and r = 0.939, respectively). PSI had positive correlation with number of taxa, and ASPT‐ETHbios (r = 0.819, and r = 0.798, respectively). Most sites were heavily sedimented.

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

بوم‌شناسی 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.

Removing invasive stream macrofauna shifts nontarget invertebrate mesofauna through facilitation

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Positive interactions among non‐native species can drive invasional meltdowns to the detriment of native biota. Here, we assessed whether targeted control of aquatic invasive species (AIS) can benefit native species by eliminating synergies among invaders.

Dynamic of epigeous macrofauna under organic soil management in the Brazilian semi-arid region
Dinâmica da macrofauna epígea sob manejo orgânico do solo no semi-árido brasileiro

Semina: Ciências Agrárias, 2012
Soil macrofauna is responsible for soil fertility through cycling of nutrients, tillage and fragmentation of organic matter, as well as through the association between groups of fauna with conserved and/or degraded pedoenvironments.

Factors affecting intraspecific diet variation of ducklings: Niche partitioning in a heterogeneous landscape?

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Variability in resource use within populations of free‐ranging animals can influence demographic and evolutionary processes. Yet in many ecological systems, the extent of intra‐population variation in the resources that animals consume and the environmental factors that contribute to this variance remain poorly understood. For example, dietary

Trophic ecology of the freshwater prawn, Pseudopalaemon bouvieri (Decapoda: Palaemonidae) in Northeastern Argentina: with remarks on population structure

Revista de Biología Tropical, 2012
Freshwater decapod crustaceans are important components of food webs in these environments, but little is known about the diet of species that live in tropical waters. We studied the feeding ecology of the prawn Pseudopalaemon bouvieri and its population

Fish predation cues induce drifting and emergence in an experimental stream mesocosm system

Limnology and Oceanography, Volume 70, Issue S2, Page S364-S376, December 2025.
Abstract Predator–prey interactions are important drivers of adaptation in aquatic communities, shaping the behavior of invertebrates with cascading effects on community dynamics. Behavioral responses, such as moving with the downstream current (drift) or altering the timing of emergence, are strategies that reduce the risk of predator encounters ...
