Ecology and distribution patterns of Chara connivens (Charophyta, Characeae) on the Canary Islands – the first record from Fuerteventura
The paper presents the first record of a Chara connivens (Characeae) stand from Fuerteventura (Canary Islands, Spain). The species was previously recorded only on Tenerife and Lanzarote, mostly in marine and artificial habitats. Physicochemical parameters
Does salinity affect body proportions and “size/mass” ratios of highly halotolerant Baeotendipes noctivagus larvae (Diptera, Chironomidae)?
Measuring the linear characteristics of chironomid larvae is easier and faster than measuring their mass. The relationships between them are approximated by parabolic equations. Generalized equations are provided for all chironomid larvae. However, these relations
Do abundance and percentage of dipteran larvae and Oligochaeta indicate low water quality in streams and lake littoral?
The presence of chironomids and/or oligochaetes is generally considered to be an indication of poor status of freshwater. Non-chironomid dipterans show unclear trends. The abundance and percentage of these groups are rarely used as potential
Changes in the composition and abundance of ichthyoplankton along environmental gradients of the southern Baltic Sea
The research focuses mainly on the ichthyoplankton of the Baltic deeps – the inflow route from the North Sea. The ichthyoplankton was represented by eggs and larvae of nine fish species: sprat, cod, herring, European
Bloom of the potentially toxic cyanobacterium P. rubescens: seasonal distribution and possible drivers of its proliferation in the Vrutci reservoir (Serbia)
Planktothrix rubescens is a filamentous cyanobacterium with a worldwide distribution in lakes and reservoirs of varying size and morphology. The objective of this study was to identify the population dynamics and the major drivers of
