Earthworm (Megadrili) ovaries are paired organs located usually in the XIII segment. So far, only their localization and general morphology well known. Light, fluorescence, electron microscopy analyses were carried out to describe ovary histology ultrastructure selected representatives of family Lumbricidae. We studied 12 species from six genera: Aporrectodea, Dendrobaena, Eisenia, Lumbricus, Octolasion, Proctodrilus. It was revealed that Lumbricidae tiny, leaf-like structures with one...

To assess the impact of Enchytraeidae (potworms) on functioning decomposer system, knowledge feeding preferences enchytraeid species is required. Different food can be explained by variations in enzymatic activities among different species, as there are no significant differences morphology or anatomy their alimentary tracts. However, it crucial to distinguish between contribution microbial enzymes and animal’s digestive capacity. Here, we computationally analyzed endogenous enzyme genes...

Abstract Phreodrilidae is a small family uniting about 50 species of minute freshwater clitellate annelids inhabiting mainly the Southern hemisphere. Other than male and spermathecal genitalia, their internal organization poorly known. Here, we present results our study ovaries oogenesis in Insulodrilus bifidus , phreodrilid from Western Australia using light electron microscopy. The are paired located segment XII. They inconspicuous composed several (10–12) spherical germ‐line cysts loosely...

Abstract Acanthobdellida gnaw into the sides of salmonid fishes in frigid Arctic lakes and rivers, latching on with fearsome facial hooks. Sister to leeches, they are an ancient lineage two described species. Unfortunately, rarely collected, leading a paucity literature despite their unique morphology. Populations range from Eurasia Alaska (USA), but few specimens Acanthobdella peledina represented molecular studies, no data exist for Paracanthobdella livanowi, making taxonomic position...

Ovaries in earthworms belonging to the family Megascolecidae are paired structures attached septum anterior part of XIII segment. They fan rosette shaped with numerous rows growing oocytes, known as egg strings, radiating from ovary center towards segmental cavity. The histological and ultrastructural organization megascolecids course oogenesis remain unknown. paper presents results light electron microscopy analyses ovaries six megascolecid species, three genus Amynthas Metaphire. Both...

Abstract Notwithstanding the genus Italobdella has been hypothesized to have doubtful taxonomic value, we decided update its diagnosis by describing new species – bieleckii sp. n. The leeches were collected from stony bottom along shore of Danube River in Slovakia. In study, implemented model leech body form and set external internal morphological characters present similarity other fish leeches. As a result, able construct key for determining belonging hoping that could be found determined...

Biological invasions are one of the greatest threats to biodiversity, economic development, and human health. Therefore an important challenge is understand mechanisms factors that facilitate spread invasive species. The Ponto-Caspian polychaete Hypania invalida invaders have been colonizing river systems in Europe since 1950s. research aim was map distribution H. upper Oder associated aquatic environments, assess contribution benthic fauna, identify environmental linked occurrence , provide...

Abstract Herein, we describe a new species of turtle blood-feeding leech, Placobdella nabeulensis sp. nov. from Palearctic North Africa (Tunisia and Algeria). The is described based on detailed morphological analyses using light scanning electron microscopes. Apart the morphology atrium, features alone do not sufficiently separate congeners due to absence distinct diagnostic characters. Therefore, turned molecular data better distinguish this other members genus establish basis for its...

Iron uptake, transport, and storage require the involvement of several proteins, including ferroportin (fpn), sole known iron efflux transporter. Due to its critical function fpn has been studied, particularly in humans. Here, we characterized gene common carp (Cyprinus carpio L.) performed RNA-seq analysis evaluate constitutive transcription levels across different tissues. Our results indicate that C. possesses two functional fpns with distinct expression patterns, highlighting potential...
