<i>Crithmum maritimum</i> L. (Apiaceae) voor het eerst in België gevonden

In 1985 Crithmum maritimum has been recorded for the first time in Belgium. The single plant is still present It is growing on the seaward side of the strongly disturbed dunefront bordering the parking zone of a road on the sea promenade at Raversijde (51°l2'N, 2°50'3O"E; IFBL/C 1.23) near Ostend. Like other continental northern records of the species (France, dep. Du Nord and Netherlands, especially Zeeland) the Belgian locality will probably be of a temporary nature

Verspreiding en populatiedynamiek van thalassochore zaadplanten aan de Belgische kust

The distribution and population dynamics of the less common strand line plants have been monitored on a yearly basis along the entire Belgian coast since 1982. Five species have been added to the Belgian flora. Due to the dynamic environment (mostly sandy coasts) most species are rare or show highly fluctuating population levels. Some measures to be taken to favour the development of strand line vegetation are proposed

Het Krabbezakje <i>Sacculina carcini</i> Thompson, 1836 op de Breedpootkrab <i>Portumnus latipes</i> (Pennant, 1777), een zeldzame associatie

On several occasions specimens of Portumnus latipes (Pennant, 1777) carrying the parasitic rhizocephalan Sacculina Carcini Thompson, 1836 were found on the Belgian east coast. This association is seldom seen. It was recorded about 100 years ago from the Atlantic coast of France

Bedenkingen bij de vondst van een Boniter, <i>Sarda sarda</i> (Bloch, 1793), aan de Belgische kust

A freshly dead Bonito Sarda sarda (Bloch, 1793) found on the beach at Blankenberge (Belgium) after a severe storm on 24 January 1986 is believed to be a genuine vagrant. The species is very rare in the southern North Sea. The only former record in the area is one of a specimen caught in 1878 in the Eastern Scheldt (The Netherlands)
