More Is Not Always Better: Selective Trait Filtering Governs Assembly Under Emerging Flow Intermittency

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
The study examined how increasing flow intermittency affects macroinvertebrate community organisation in newly drying headwater streams. Results showed that drying selectively filters species and trait states, with resistance‐ and resilience‐related survival strategies responding differently to increasing intermittency.

Eight years of monitoring aquatic Oligochaeta from the Baía and Ivinhema Rivers

open access: yesBrazilian Journal of Biology
The aim of this study was to analyze the factors that influence spatial and temporal variations of the Oligochaeta assemblage in the Baía and Ivinhema Rivers, located in the Upper Paraná River floodplain (Mato Grosso do Sul State, Brazil).

Quantification of Fish Littoral Carbon Use and Trophic Position Using Stable Isotopes: An Empirical Comparison of Equations Using Freshwater Lakes

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Standardizing stable isotope values with these metrics allows for comparison across different systems and time scales; however, several equations to quantify LCU and TP have been introduced with little guidance on the bias and limitations of each equation, or how and when different equations should be used.

Tributaries as richness source for Oligochaeta assemblage (Annelida) of Neotropical dammed river

open access: yesBrazilian Journal of Biology
Tributaries may serve as richness source for the river main channel and the zoobenthos community is a good tool to verify this kind of pattern. In this study, we aimed to characterize the benthic invertebrate assemblage in three tributaries associated to

Remarks on the Dendrobaena kozuvensis (Šapkarev, 1971) species group (Oligochaeta, Lumbricidae) [PDF]

open access: yesOpuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis
New material of the earthworm species Dendrobaena kozuvensis were collected from a cave in the Lovćen Mts. in Montenegro. In this study, a detailed morphological description of the specimens is given and the relationships of this species are discussed ...

Height and phytotelm size affect the invertebrate communities of epiphytic bromeliads in the Amazon rainforest

open access: yesEcological Entomology, Volume 51, Issue 2, Page 221-234, April 2026.
The height at which epiphytic bromeliads are found affects the invertebrate community composition within them. The size of epiphytic bromeliads is positively correlated with species richness of both aquatic and terrestrial invertebrates. Whether bromeliads were found in primary or secondary forest did not have a significant effect on the community of ...

Algunas consideraciones sobre los estudios actuales de la reproducción de los oligoquetos

open access: yesActa Zoológica Lilloana, 2020
El estado actual del problema de la reproducción entre los Oligochaeta se esboza aquí, con especial referencia al modo uniparental. Los métodos de exploración en esta esfera se amplían y se esboza tentativamente una clasificación eventual de las ...

Oligochaeta (Annelida: Clitellata) associated to aquatic macrophytes in Brazil

open access: yesBiotemas, 2016
Oligochaeta are still characterized as a poorly studied group among the aquatic macroinvertebrates and few studies about their ecology were conducted in Brazil.

Using oligochaeta assemblages as an indicator of environmental changes

open access: yesBrazilian Journal of Biology
We designed a field survey (the entire river length; not dammed: First and Second plateaus; dammed: Third Plateau) to test the hypothesis that the cascade of reservoirs promoted a reduction in species richness and changed the composition of Oligochaeta ...
