| A seed in the collection of the Rijksherbarium from the Dutch coast (1971) appears to belong to Pangium edule. Although able to drift for a long time, it is improbable that this Malaysian seed reached the Dutch coast all the way by sea currents. Transport by man to NW. Europe is the most probable explanation for its occurrence on the Dutch coast. Import of tropical seeds and fruits particularly for decoration has increased. As a result it becomes more difficult to prove longdistance transport by sea for tropical drift-seeds found on the Dutch coast. |

| Dr Margaretha Brongersma-Sanders, palaeontologist, pioneer geochemist, geobiologist and oceanographer, Officer of the Order of Oranje Nassau was born 100 years ago (February 20th, 1905) in Kampen in The Netherlands. The fields of research that she covered during her lifetime include taxonomy of recent and fossil, principally freshwater fish; “fish kills” and mass mortality in the sea (especially of fish); taphonomy and preservation of fish; upwelling; anoxic conditions, linked to fish mortality and the origin of bituminous black shales and oil; red tides and harmful algal blooms; trace metal enrichment in recent and fossil sediments, especially the Kupferschiefer; the origin of evaporites; algal mats and stromatolites. She was the first to categorise fish... |

| The actual and fossil distribution patterns of the aquatic gastropod genera Tryonia and Planorbarius indicate that avian dispersal was an important dispersal mechanism in the geological past. Combining the distribution histories of these genera with ecological data on modern relatives provides insights into the process of dispersal of aquatic taxa in general. Avian dispersal of aquatic taxa is facilitated by a variety of factors, including mass occurrence in resting/foraging places of migrating birds, ways to attach to the birds and to overcome desiccation during flight, as well as easy reproduction from a single specimen when introduced into a new habitat. The uncertain taxonomical status of aquatic organisms, as well as biased preservation and sampling,... |
