Anthropogenic drivers of molluscs dispersion in tributaries of the Vistula and Odra rivers with different degrees of secondary salinization

Anthropogenic drivers of molluscs dispersion in tributaries of the Vistula and Odra rivers with different degrees of secondary salinization

Lewin I., Halabowski D. iga.lewin@us.edu.pl Salinisation that is triggered by human activity within the catchment such as land development, agriculture, discharge of industrial liquid or solid waste and mining, is called secondary salinisation. Secondary salinisation has become a hot spot internationally due to its adverse effects on freshwater ecosystems. In the Upper Silesian Coal Basin …

Study of biofouling on an offshore rig in the Baltic Sea

Study of biofouling on an offshore rig in the Baltic Sea

Kur J., Igliński P., Galant G., Mioduchowska M. jarek.kur@gmail.com Biofouling is called “lessons from nature”. For as long as we can remember, man has struggled with the problem of unwanted biofouling of immersed elements. In modern times, biofouling on artificial structures has become a transfer vector of invasive species. “Artificial islands” become a kind of …

Selected behavioural traits of some European hygrophilous whorl snails (Gastopoda: Eupulomata: Vertiginidae)

Selected behavioural traits of some European hygrophilous whorl snails (Gastopoda: Eupulomata: Vertiginidae)

Książkiewicz-Parulska Z. ksiazkiewicz@amu.edu.pl Whorl snails are superfamily associating tiny land snail species. Most of them demand a high (or very high) humidity for life and reproduction. Therefore, vertiginids may be usually found dwelling in wetlands, humid meadows, or woodlands. Alterations in the natural environment resulting from a human interference and climate crises contributed toward heat …

Phylogeography of Depressed River Mussel Pseudanodonta complanata in Russia

Konopleva E.S., Kondakov A.V., Tomilova A.A., Vikhrev I.V., Lyubas A.A., Bolotov I.N. es.konopleva@gmail.com The Depressed River Mussel Pseudanodonta complanata (Rossmässler, 1835) represents an Anodontini taxon (Bivalvia: Unionidae), being considered one of the most rare European unionid species, especially in Central and Eastern Europe. In Russia, P. complanata ranges throughout freshwater bodies of the Baltic, Azov, …

A molecular identification of trematodes of the genus Diplostomum in lymnaeid snail from Arctic lakes

A molecular identification of trematodes of the genus Diplostomum in lymnaeid snail from Arctic lakes

Khrebtova I.S., Aksenova O.V., Kondakov A.V irinahrebtova@bk.ru Trematodes of the genus Diplostomum have a complex life cycle which includes the change of two intermediate hosts. At the first stage of development the egg of the trematode turns into a miracidium which infects a freshwater gastropods from the Lymnaeidae family and passes into the sporocyst or …

New data on biodiversity of dorid nudibranchs (Gastropoda: Heterobranchia) in Southern Vietnam

New data on biodiversity of dorid nudibranchs (Gastropoda: Heterobranchia) in Southern Vietnam

Indriksone J.V., Deart Yu.V., Antokhina T.I., Ekimova I.A. indriksonne@gmail.com Nudibranchia is a group of shell-less and strikingly-colored marine molluscs, encountering more than 4000 species. They are distributed worldwide with the highest diversity in the Indo-West Pacific region. Despite there are a lot of researches dedicated to regional fauna composition and distribution, some regions still remain …

The mitochondrial genomes of two species within the Melampus bidentatus species complex (Panpulmonata; Ellobioidea)

The mitochondrial genomes of two species within the Melampus bidentatus species complex (Panpulmonata; Ellobioidea)

Inäbnit T., Dennis A.B. inaebnit.thomas@gmail.com Melampus bidentatus is a complex of three cryptic species that are an important component of the salt marsh communities along the North American east coast and the Gulf of Mexico. We assembled the mitochondrial genome of the cryptic species M. bidentatus “North” and “South” from Illumina short read data using …

Freshwater Mussel Removes Bacterial Pathogen

Freshwater Mussel Removes Bacterial Pathogen

Hajisafarali M., Aaltonen S., Pulkkinen K., Taskinen J. mahsa.m.hajisafarali@jyu.fi Decline of freshwater mussels (Unionida) is a global phenomenon, threatening biodiversity and the essential ecosystem services that mussels provide. Freshwater mussels can clear the water by filtering suspended particles, such as phytoplankton, but they can also remove bacteria from the water and therefore decrease the risk …

Sex ratio in invasive freshwater bivalve species: a meta-analysis

Sex ratio in invasive freshwater bivalve species: a meta-analysis

Guimarães M., Torres A.L.Q., Serra A.C.S., Coutinho R.A., Americo J.A., de Freitas Rebelo M. murilo.guimaraes@biobureau.com.br The comprehension of demographic parameters of invasive bivalve species is fundamental to achieve successful management strategies. Sex ratio is a central parameter of population structure, directly influencing survival, reproduction and abundance, and thus, knowledge on the proportion of sexes can …

Population growth of the intertidal mollusk Chiton articulatus (Polyplacophora: Chitonida) at its northernmost distribution limit in Mexico, based on length data

Population growth of the intertidal mollusk Chiton articulatus (Polyplacophora: Chitonida) at its northernmost distribution limit in Mexico, based on length data

Guillen C., Rodriguez-Dominguez G., Avila-Poveda O.H camilaguillen_posgrado@uas.edu.mx; oavila@uas.edu.mx Growth is an important life history trait that can be related to environmental features or can be implemented to characterize populations. This study examined growth by Schnute growth models based on length data for an edible intertidal invertebrate with indeterminate growth: Chiton articulatus. The geographical distribution of …
