| The apparent influence of climatic change on recent changes of range by European insects (Lepidoptera, Orthoptera) For several years I have been collecting data concerning changes in the ranges of European insects, especially Lepidoptera and Orthoptera. The vast majority of those species which have altered their ranges since 1850 have spread to the north, north-west or west (e.g. 96% of the Lepidoptera expanding their ranges). Of the smaller number of species where the range has contracted, the majority (e.g. 75% of the Lepidoptera) have retreated southwards, south-westwards or south-eastwards. I have attempted to correlate these range changes with the main climatic fluctuations from 1850 to the present. Throughout this long period of predominately... |

| Recent changes in distribution of dragonflies in Switzerland (Odonata) In 1998 the Swiss Centre for the Cartography of Fauna (CSCF) initiated ‘Odonata 2000’. This project aimed at testing a method for periodical reassessment of Red Lists in Switzerland. The study was carried out on Odonata and consisted of the resampling of known localities of threatened species and the sampling of new localities. Based on the number of sites where a given species has been found in the periods 1970-1998 and 1999-2000, trends were calculated for each species. The results show that since 1994 three species have disappeared from Switzerland, nine species have declined, two species have increased and 64 species have remained stable. Crocothemis erythraea, Lestes virens,... |

| Some fifty years after the Snellius I expedition (1929-1930) a Dutch-Indonesian joint expedition is carried out (1984-1985) in the Eastern Indonesian archpelago. Based on two months (September -October 1984) of research at nine different reef localities, a first report will be presented on the general morphology, composition and condition of recent and fossil reefs of these areas. The research areas that will be discussed are the following: Ambon: In the bay of Ambon fringing and patch reefs heavily damaged by silting up, caused by soi1. erosion on the island. North East Ambon an elevated reef from the old Pleistocene. Lucipara islands: Exposed very isolated atoll with some sand cays. Tukang Besi islands: Atoll reefs of Kaledupa. Binongko reef terraces;... |
