This study analysed recent macrophyte vegetation and the reproductive potentia...Anthropogenic disturbance over several decades has caused aquatic ecosystems to deteriorate, raising concerns about their condition and, consequently, prompting restorative activities.
The pronounced salinity gradient, co‐occurrence of multiple stressors, and a...The Baltic Sea, a young habitat in geological terms, is characterised by strong climatic and salinity gradients that determine species distribution and trigger adaptation processes. Ecology and distribution of sexuals i...Parthenogenetically reproducing Chara canescens (Charophyceae) populations have been described from several European locations.

Z noltii showed the potential to grow in mes...Acclimation of the photosynthetic apparatus to light absorbed primarily by phycobilisomes (which transfer energy predominantly to photosystem II) or absorbed by chlorophyll a (mainly present in the antenna of photosystem I) was studied in the macroalga Palmaria palmata L. In addition, the influence of blue and yellow light, exciting chlorophyll a a...Paleolimnological techniques were used to identify environmental changes in and around Lake Dudinghausen (northern Germany) over the past 4800 yr. Diatom-inferred total phosphorus (DI-TP) changes identify four phases of high nutrient levels (2600–2200 BC, 1050–700 BC, 500 BC–AD 100 and AD 1850–1970).

Despite the enticing discoveries of chaos in nature, triggers and drivers of this phenomenon remain a classical enigma which needs irrefutable empirical evidence. Oh Heiland, steh uns bei!

Wieso es um weit mehr als IT-Outsourcing geht. Se sentir en sécurité chez soi – ce n'est pas une évidence. The best way...This study analyses three decades of the peculiar bloom-formation history of the potentially toxic invasive planktonic dinoflagellates Prorocentrum minimum (Pavillard) Schiller in the SW Baltic Sea. The founders and managing directors Hendrik Schubert and Dr. Erik Wende remain in their positions and will retain a significant share in the company. The unicellular green alga Chlamydomonas acidophila accumulates in a thin phytoplankton layer in the hypolimnion (deep chlorophyll maximum, DCM) of an extremely acidic lake (Lake 111, pH 2.6, Lusatia, Germany), in which the underwater light spectrum is distorted and red-shifted. mean grain size, sorting level, silt fraction, lime and organic matter as well as content of total carbon, total nitrogen and total phosphorus) in four brackish lagoons in northeastern Germany (southern Baltic Sea).

Especially in the genus Chara there is no generally accepted catalogue of oospore characters and the existing determination keys do not include brackish water material.
