Polyploid races, genetic structure and morphological features of earthworm Aporrectodea rosea (Savigny, 1826) (Oligohaeta: Lumbricidae) in Ukraine [PDF]

, 2011
Four chromosomal races (2n=36, 3n=54, 6n=108, 8n=144) and 96 clones have been revealed among 224 specimens of the earthworm A. rosea over the territory of Ukraine by means of karyological analysis and biochemical genetic marking.

Impacts of Land Use and Water Quality on Macroinvertebrate Diversity Under Human Disturbance in the Lake Chaohu Basin, China

Ecology and Evolution, Volume 15, Issue 11, November 2025.
Our study revealed that human activities drive changes in macroinvertebrate diversity through the combined effects of land use and water quality. The results showed that sensitive taxa (Semisulcospira cancelata) dominated in low disturbance areas, Bellamya (Bellamya aeruginosa) and Alocinma (Alocinma longicornis) were predominant in moderate ...

Invertebrates on isolated peaks in the uKhahlamba-Drakensberg Park World Heritage Site, South Africa

Koedoe: African Protected Area Conservation and Science, 2012
A survey to document and describe the alpine flora and various focal faunal taxa on six isolated inselberg-like peaks (total area of 31.9 ha), all 3000 m or higher, located in the uKhahlamba-Drakensberg Park World Heritage Site, South Africa, was ...

Molecular phylogeny of Enchytraeidae (Oligochaeta) indicates separate invasions of the terrestrial environment

, 2010
Enchytraeidae is a family of soil inhabiting small- to medium-sized oligochaete worms using degradable plant material as a food source and primarily adapted to terrestrial or semi-terrestrial environments.

Repeated Visits to a Woman With Suspected Worms Discharged From the Urethra—A Case Study

Clinical Case Reports, Volume 13, Issue 10, October 2025.
ABSTRACT A 58‐year‐old female presented with a 6‐month history of recurrent “worms” found in her toilet, which she suspected originated from her urinary tract. Physical examination was unremarkable. Laboratory analysis revealed motile, blood‐red worm‐like organisms measuring 25–35 mm in length, initially suspected to be Dioctophyma renale larvae ...

Biodiversity in mountain soils above the treeline

Biological Reviews, Volume 100, Issue 5, Page 1877-1949, October 2025.
ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...

Habitat‐Specific Response of Macroinvertebrate Drift to Flow Pulses: Implications for Hydropeaking Management

Freshwater Biology, Volume 70, Issue 10, October 2025.
ABSTRACT Flow pulses play a vital role in maintaining the ecological functioning of natural river systems. However, anthropogenic flow regulation, particularly from hydropower operations, can introduce rapid and unnatural pulses that negatively impact aquatic biota.

Sucessão de invertebrados durante o processo de decomposição de duas plantas aquáticas (Eichhornia azurea e Polygonum ferrugineum) = Succession of invertebrates during the decomposition process of two aquatic plants (Eichhornia azurea and Polygonum ferrugineum)

Acta Scientiarum: Biological Sciences, 2006
A colonização de invertebrados durante o período de 56 dias de decomposição de duas espécies de plantas aquáticas (Eichhornia azurea e Polygonum ferrugineum) foi investigada para determinar o papel de macroinvertebrados no processo de fragmentação da ...

Land Use Impacts on Local and Regional Freshwater Biodiversity Can Compromise Current Management Goals

Global Change Biology, Volume 31, Issue 10, October 2025.
Using nationwide survey data on stream diatoms and macroinvertebrates, as well as lake diatoms, macroinvertebrates, and macrophytes, combined with multitaxon distribution models, we demonstrated that land use has negatively affected both local and regional biodiversity across all examined communities.
