The cytotaxonomic study of theVicia cracca complex 2. The taxa of the southern part of northern Europe

In the southern parts of Scandinavia there occur two species of theVicia cracca L. complex:Vicia cracca L., represented by the chromosome race 2n=28, andV. oreophila ?ertová. WhereasV. oreophila predominantly inhabits habitats of primary character, especially near the coast, the tetraploid race ofV. cracca, which is the commonest in other parts of area, occurs predominantly on sites of secondary character, such as the borders of paths, roads, meadows and bushy places. The two species differ in several characters.

Invasive round goby Neogobius melanostomus has sex‐dependent locomotor activity and is under‐represented in catches from passive fishing gear compared with seine catches

The higher proportion of males of the invasive round goby Neogobius melanostomus in samples from two activity selective passive fishing gears compared with one activity non‐selective fishing gear in three Dutch lakes is related to higher male locomotory activity and is a sex‐dependent trait. This difference in activity reflects the different ecology of male and female N. melanostomus.
