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

Ecology 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.

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

Brazilian 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).

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

Ecological 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 ...

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

Brazilian 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]

Opuscula 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 ...

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

Acta 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 ...

The Potential of Oligochaeta as Intermediate Host of Myxosporea Parasite in Common Carp (Cyprinus carpio Linnaeus)

Jurnal Akuakultur Indonesia, 2003
Three genera of oligochaeta, i.e. Branchiura sowerbyi, Limnodrillus sp. and Lumbriculus sp. were fed on spores of Myxobolus artus before predated to juvenile of Cyprinus carpio. Spores of myxosporean were found on the fish, which get Limnodrillus.

Basic Research Tools for Earthworm Ecology [PDF]

, 2010
Earthworms are responsible for soil development, recycling organic matter and form a vital component within many food webs. For these and other reasons earthworms are worthy of investigation. Many technologically-enhanced approaches have been used within

Translocating Intact Assemblages to Degraded Sites to Accelerate Ecological Recovery

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
Estuarine ecosystems are threatened by anthropogenic pressures such as climate change, coastal development, and increased nutrient and sediment inputs. These pressures are deteriorating ecological health and threatening the functioning and services that estuarine ecosystems provide.

Using oligochaeta assemblages as an indicator of environmental changes

Brazilian 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 ...
