Community Structure of Benthic invertebrate in Greater Zab River/Iraq [PDF]
A study_ of macroinvertebrate community has been carried out at three sites selected on greater zab river included Qandel, Efraz and Khabat region. A total of 32 species of benthic invertebrates were recorded including Nematoda, Oligochaeta, Ostracoda ...

Polyploid races, genetic structure and morphological features of the earthworm Octodrіlus transpadanus (Rosa, 1884) (Oligohaeta: Lumbricidae) in the Ukraine [PDF]
Kariological investigation of the earthworm Octodrilus transpada-nus (Rosa, 1884) in the Ukraine showed that this species is represented by at least three races of different ploidy with the basic chromosome number n=15. Strict geographic heterogeneity

Comparison of bioassessment results and costs between preserved and unpreserved macroinvertebrate samples from streams [PDF]
The choice to use or not use a preservative before sorting macroinvertebrate samples (i.e., dead specimens vs. living specimens) is based on studies not solely focused on the effects of preservation.

Biofloc technology and periphyton‐based systems enhance the sustainable production of giant freshwater prawn (Macrobrachium rosenbergii). A PRISMA‐guided review (2005 – 2024) shows that BFT improves survival (75 – 78 %) and feed efficiency, while periphyton supports natural productivity in grow‐out.

First record of Bothrioneurum vejdovskyanum Štolc, 1886 (Oligochaeta, Tubificidae) in Serbia [PDF]
We report the discovery of Bothrioneurum vejdovskyanum Štolc, 1886 (Annelida: Oligochaeta: Tubificidae: Rhyacodrilinae) in Serbian freshwaters. Fifteen specimens were found in the middle course of the River Ibar (southern Serbia), at a locality where ...

ABSTRACT The piscicide antimycin has been used as an effective fish toxicant to eradicate nuisance fishes because it is not as detectable by fish as other chemical piscicides. We evaluated the effects of antimycin and its detoxicant, potassium permanganate, on periphyton and benthic macroinvertebrates during a brook trout (Salvelinus fontinalis ...

Asymmetrical hybridization and gene flow between Eisenia andrei and E. fetida lumbricid earthworms [PDF]
Uniformly pigmented Eisenia andrei (Ea) and striped E. fetida (Ef) lumbricid earthworms are hermaphrodites capable of self-fertilization, cross-fertilization, and asymmetrical hybridization.

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.

Description of two new actinosporean types from a brook of Fuji Mountain, Honshu, and from Chitose River, Hokkaido, Japan [PDF]
Actinospore infection of oligochaetes living in the mud of 3 freshwater biotopes in Japan was studied. Using the cell-well plate method, a new aurantiactinomyxon type was found in 0.77 % of the examined Tubifex tubifex oligochaete specimens from a brook ...
