Traditional biotopes, environment maintained with traditional agricultural methods, are among our most diverse environments. Their area has decreased significantly, which has compromised the persistence of the species specialized in these habitats. Road verges have proved as a potential alternative habitat for various taxa typical of traditional biotopes. In my study, I focused on a common yet little-studied animal order: spiders. With pitfall traps, I collected material from three habitat types \u2013 meadows, pastures, and road verges \u2013 around central Finland during a six-week period. I studied if there are differences in spider diversity between meadows and pastures, and how well road verges are capable of maintaining the diversity of traditional biotopes. The numbers of individuals between the habitat types did not differ from each other. It turned out, however, that pastures are slightly more species-poor than the other two habitats. From the perspective of the conservation of traditional bioptopes, the more important observation was that road verges are even more diverse than meadows. The results cannot be generalized to cover the entire spider communities of the studied habitats. The topic needs further research, but my study suggests, nevertheless, that road verges possess significant conservational value that is worth taking into consideration in the future, when the area of traditional biotopes continues to decrease.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2020-06-26T05:45:24Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-06-26T05:45:24Z (GMT).
