Modeling Aquatic Macroinvertebrate Richness Using Landscape Attributes
We used a rapid, repeatable, and inexpensive geographic information system (GIS) approach to predict aquatic macroinvertebrate family richness using the landscape attributes stream gradient, riparian forest cover, and water quality. Stream segments in the Allegheny River basin were classified into eight habitat classes using these three landscape ...

ABSTRACT Freshwater mussels are a globally threatened taxon, but little is known about population trajectories for species outside Europe and North America. To contribute to understanding of mussel conservation status outside these regions, we surveyed mussel and other invertebrate populations in waterbodies across Dhaka, Bangladesh, to assess ...

The fossil record of freshwater Gastropoda – a global review
ABSTRACT Gastropoda are an exceptionally successful group with a rich and diverse fossil record. They have conquered land and freshwater habitats multiple times independently and have dispersed across the entire globe. Since they are important constituents of fossil assemblages, they are often used for palaeoecological reconstruction, biostratigraphic ...

The study of the trematodes of the family Notocotylidae Lühe, 1909, is continued using an integrated approach based on new data. A new genus, Pseudonotocotylus n. gen., has been identified, and two species new to science, Notocotylus multipapillus n. sp. and Pseudonotocotylus martynenkoi n. sp., have been discovered.

BITHYNIA SHAPKAREVI N.SP., A NEW SPECIES FROM PRESPA LAKE, R. MACEDONIA (GASTROPODA: BITHYNIIDAE)
From Macedonia only Bithynia prespensis Hadžišče, 1963 is known so far. Recent investigations in Prespa Lake revealed a new Bithynia species, Bithynia shapkarevi n. sp. which is described here. Holotype and a paratype in addition to the penis morphology are depicted. The new Bithynia species has been compared with all known Bithynia spp.
