We assembled information on 119 species
of freshwater macroinvertebrate invaders in
North America and Europe, and compared them to
all native freshwater species in North America and
Europe. We tested whether the invaders were a
random or selected group among taxa (phylum or
class), water quality requirements, and feeding habit.
We found that freshwater macroinvertebrate invaders
are not a random selection of species, and are overrepresented
by molluscs and crustaceans, while taxa
richness of native communities are dominated by
insects. Over 35% of native species of aquatic
invertebrates in North America are only able to live
in areas with excellent or very good water quality,
and are intolerant of organic pollution. In contrast, all
invaders are tolerant of at least moderate amounts of
organic pollution. There was a significant difference
in the distribution of feeding habits between native
species and invaders: collector-filterers (including
suspension feeders) were 2.5–3 times more abundant,
and predators were 3–4 times less abundant among
invaders than among native invertebrates. The ongoing
spread of exotic species affects the biodiversity of
selected taxa, shifts communities toward greater
tolerance of organic pollution and increases the
numbers of suspension feeders, thereby enhancing
benthic pelagic coupling in waterbodies with high
densities of invaders. Because these processes are
very similar in Europe and North America, we
suggest that the observed patterns may have a
common global effect.

We analyzed the role of the waterways of Belarus in the spread of aquatic exotic invertebrates through the central European invasion corridor. Present day Belarus became critically important when in the end of the 18th—beginning of the 19th century three interbasin canals connecting rivers from the Black and Baltic seas basins were constructed for
international trade. These canals became important pathways facilitating the spread of aquatic alien species. For more than a hundred years, only Ponto-Caspian species colonized Belarus using ships and especially timber in rafts exported by Russia into Western Europe. In the second half of the 20th century, new vectors of spread appeared in Belarus, such as stocking of economically important invertebrates and accidental introductions. This paper is the first comprehensive review of aquatic exotic invertebrates in Belarus. Currently, 19 exotic aquatic invertebrates are known in Belarus, including 14 species of Ponto-Caspian origin. The rate of spread of aquatic invasive species in the second half of the 20th century increased 7-fold compared to the 19th—beginning of the 20th century. We found a significant positive correlation between the time since initial invasion and number of waterbodies colonized. We predict a further increase in the rate of colonization of Belarus by exotic invertebrates as well as an increase in the diversity of vectors of spread and donor areas of alien species, especially when the ongoing reconstruction of the interbasin canals will be completed
and the hydrological connection between Black Sea and Baltic Sea basins will be reestablished after an interruption that has lasted for almost a century.
