The unmasking of a sub-antarctic endemic : Psammothidium abundans (Manguin) Bukhtiyarova et Round in European rivers Plantentuin Meise / Agentschap Plantentuin Meise
Psammothidium abundans (Manguin) Bukhtiyarova & Round was described 50 years ago from the sub-Antarctic Kerguelen archipelago (southern Indian Ocean). Apart from single occurrences in South Africa, southern Australia and Tierra del Fuego, the reported distribution of this species is restricted to the (sub-)Antarctic Region. In the northern hemisphere, the species was only very sporadically reported from two rivers in Scotland. During surface ...
New and interesting species in the genus Luticola D.G. Mann (Bacillaiophyta) from Deception Island (South Shetland Islands) Plantentuin Meise / Agentschap Plantentuin Meise
During a survey of the terrestrial diatom flora of Deception Island (South Shetland Islands, southern Atlantic Ocean), 10 taxa belonging to the genus Luticola were observed. Five of these, namely Luticola gigamuticopsis sp. nov., L. caubergsii sp. nov., L. quadriscrobiculata sp. nov., L. nelidae sp. nov. and L. australomutica sp. nov., are described as new species using light and scanning electron microscopy. Comments are made on their ...
The genus Eunotia on the volcanic island, Ile Amsterdam (Southern Indian Ocean) Plantentuin Meise / Agentschap Plantentuin Meise
During a preliminary survey of the non-marine diatom flora of the volcanic island, Île Amsterdam (southern Indian Ocean), five species belonging to the genus Eunotia have been found. Apart from Eunotia paludosa var. paludosa and E. muscicola var. muscicola, three appear to be new to science and are described as E. pugilistica Van de Vijver sp. nov., E. lecohui Van de Vijver sp. nov. and E. cocquytiae sp. nov. All species are fully investigated ...
Pinnularia obaesa sp. nov. and P. australorabenhorstii sp. nov, two nem large Pinnularia (Sect. Distantes) from the antarctic King George Island (South Shetland Islands) Plantentuin Meise / Agentschap Plantentuin Meise
A recent survey of the non-marine diatoms of the South Shetland Islands (southern Atlantic Ocean) resulted in the discovery of two unusual species of the genus Pinnularia, section Distantes. Based on both light and scanning electron microscopical research, both species are described as new species: Pinnularia obaesa sp. nov. and P. australorabenhorstii sp. nov. The morphology of both species is compared to other, similar species of the section ...

Responses of aquatic organisms to metal pollution in a lowland river in Flanders : a comparison of diatoms and macroinvertebrates Plantentuin Meise / Agentschap Plantentuin Meise
The role of macroinvertebrates and diatoms as indicator for metal pollution was investigated by assessing both biota along a metal gradient in the Belgian river the Dommel. Macroinvertebrates and diatoms were sampled in summer and winter and physical-chemical characteristics of the water were measured at four different sample periods and related to sediment characteristics. Although metal concentrations, except cadmium, in the water nowhere ...
