Comparative ecotoxicological assessment of nano-formulated and conventional copper-based pesticides on the freshwater snail Planorbarius corneus

open access: yesEcotoxicology and Environmental Safety
Copper (Cu) is extensively used in agriculture, yet its environmental accumulation raises significant ecotoxicological concerns. Nano-formulations have been developed as alternatives allowing to decrease Cu application rates, but their effects on non ...

Heterochromatin in a Pulmonate Snail,Planorbarius CorneusL.

open access: yesCaryologia, 1982
SUMMARYConstitutive heterochromatin has been identified in the small chromosomes of a hermaphroditic pulmonate snail, Planorbarius corneus L. by its staining properties and its asynchronous replication relative to euchromatin. Constitutive heterochromatin is located in the telomeric regions of some chromosomes and is suggested to be involved in the ...

Effects of External Calcium Concentrations on Calcium uptake in Freshwater Snail Planorbarius Corneus L.

open access: yesCroatian Journal of Fisheries
Calcium content of water is of fundamental importance for freshwater snails since it is correlated with growth rates, egg fertility and fecundity. In this study, calcium uptake from the external medium (tap water) in two groups of freshwater snail ...

Karyological Features of the Genus Planorbarius (Gastropoda, Pulmonata, Bulinidae) of the Ukranian Fauna

open access: yes, 2007
The absence of significant distinctions between the species of the genus Planorbarius in the narrow sense (P. corneus, P. banaticus, P. purpura, and P. grandis) has been established. All investigated species had identical chromosomal formulas (2n= 30 m +

The Embryonic Development of Great Ramshorn Planorbarius Corneus under the Hypomagnetic Field [PDF]

open access: yesAmerican Journal of Life Sciences, 2015
The effect of a 100-300-fold attenuated geomagnetic field on the embryonic development of great ramshorn Planorbarius corneus and oxidation-reduction properties in water environment were studied in a hypomagnetic chamber. Mainly the hypomagnetic field effected beneficial influence on the development of mollusks: teratogenic effects were less massive, i.

Isolation and characterization of an agglutinin present in the haemolymph of the freshwater snail Planorbarius corneus (L.) (Gastropoda, pulmonata)

open access: yes, 1986
1. 1. An agglutinin was isolated from the haemolymph of Planorbarius corneus by affinity chromatography on Sephadex gel G 150. 2. 2. Molecular weight of the agglutinin as determined by polyacrylamide gel electrophoresis was 130,000 daltons. 3. 3.

Tentacle regeneration in Planorbarius corneus (Linnaeus, 1758) and Cepaea hortensis (O.F.Muller, 1774) (Gastropoda: Pulmonata)

open access: yes, 2000
Tentacle regeneration in Planorbarius corneus (L.) and Cepaea hortensis (O. F. Müll.) is found to depend on the extent of injury and the season; the regeneration time is longer in the stylommatophoran Cepaea than in the basommatophoran ...
