项目摘要

One of major purposes of our project is to obtain good onychophoran (peripatus) strains for neurobiology from a view point of phylogeny. In order to breed onychophorans, we need original living materials.We searched any kind of reports concerning Onychophora to konw places collecting peripatus. The most places where the animals were collected are located Carribean countries, so that we explored countries in the Carribean Sea such as Belize, Puerto Rico, Venezuela and Trinidad which are lands of the Gondwanian lineage. We have first been to Belize and Puerto Rico in December, 1995 and then to Venezuela and Trinidad in March, 1996. These periods were in the dry season in the year in the said countries. We read that the dry season was better to collect peri-patus because they often to gather at a particular places. We could fortunately find an unidentified species at a tropical rain forest in Puerto Rico and Macroperipatus torquatus beside a stream in a tropical rain forest in Trinidad. However, it was tough works to find peripatus in these trips. We suspect reasons for the difficulty that population of peripatus has already gotten small or we could not get to appropriate points where they had ga-thered. If in the latter case, our surveys should be carried out during the rainy season such as a period from May to September in those areas. We are thinking areas around Arima valley in Trinidad as one of the best place to look for peripatus next time because it involves a research station which offers a base camp for animal exploring.

我们项目的主要目的之一是从系统发育的角度获得用于神经生物学的良好甲虫（peripatus）菌株。为了培育甲虫，我们需要原始的活体材料。我们查阅了有关甲虫的各种报道，了解采集甲虫的地点。采集动物的地方最多的是加勒比海国家，因此我们探索了加勒比海的国家，如伯利兹、波多黎各、委内瑞拉和特立尼达，这些都是冈瓦尼亚血统的土地。我们首先于1995年12月访问了伯利兹和波多黎各，然后于1996年3月访问了委内瑞拉和特立尼达。这些时期正值上述国家当年的旱季。我们读到，旱季更适合收集周边植物，因为它们经常聚集在特定的地方。幸运的是，我们在波多黎各的热带雨林中发现了一种身份不明的物种，在特立尼达岛的热带雨林中的一条小溪旁发现了Macroperipatus torquatus。然而，在这些旅行中寻找peripatus是一件很困难的事情。我们怀疑造成这种困难的原因是，peripatus 的数量已经减少了，或者我们无法到达它们聚集的适当地点。如果是后者，我们的调查应该在这些地区的雨季进行，比如5月到9月。我们认为特立尼达的 Arima 山谷周围地区是下次寻找 peripatus 的最佳地点之一，因为它涉及一个研究站，为动物探索提供了大本营。
