Biodiversity is unequally spread throughout terrestrial ecosystems. The highest species richness of animals and plants is encountered around the Equator, and naturalists observe a decrease in the number of creatures with increasing latitude. Some animal groups, however, display an anomalous species richness pattern, but these are exceptions to the general rule. Crane flies (Diptera, Tipuloidea) are small to large sized, non-biting nematoceran insects, being mainly associated with moist environments. The species richness of crane flies is highest in the tropics, but these insects are species rich and abundant in all biogeographic realms, boreal and arctic biomes included. The phylogeny and systematics of crane flies are still at an early stage and somewhat controversial. New species are constantly discovered even from temperate Europe, faunistically the best known continent. Crane flies have been rather neglected group of insects in Finland. The history of Finnish crane fly taxonomy and faunistics started in 1907, the year when Carl Lundström published his two first articles on tipuloids. Within roughly 100 years there have been only a handful of entomologists studying the Finnish fauna, and the species richness and natural history of these flies have remained poorly understood and mapped. The aim of this thesis is to clarify the taxonomy of Finnish crane flies, present an updated and annotated list of species and seek patterns in regional species richness and assemblage composition. Tipula stackelbergi Alexander has been revised (I). This species was elevated to a species rank from a subspecific rank under T. pruinosa Wiedemann and T. stackelbergi was also deleted from the list of European crane flies. Two new synonyms were found: T. subpruinosa Mannheims is a junior synonym of T. freyana Lackschewitz and T. usuriensis Alexander is a junior synonym of T. pruinosa. A new species Tipula recondita Pilipenko & Salmela has been described (II). Both morphology and COI (mtDNA) sequences were used in the assessment of the status of the species. The new species is highly disjunct, known from Finland and Russian Far East. A list of Finnish crane flies was presented, including the presence of species in the Finnish biogeographical provinces (III). A total of twenty-four species were formally reported for the first time from Finland and twenty-two previously reported species were deleted from the list. A short historical review on the studies of Finnish crane flies has been provided. The current list of Finnish species consists of 338 crane flies (IV, Appendix I). Species richness of all species and saproxylic/fungivorous species is negatively correlated with latitude, but mire-dwelling species show a reversed species richness gradient (i.e. an increase in the number of species toward north). Provincial assemblages displayed a strong latitudinal gradient and faunistic distance increased with increasing geographical distance apart of the provinces. Nearly half (48 %) of the Finnish crane flies are Trans-Palaearctic, roughly one-third (34 %) are West Palaearctic and only 16 and 2 % are Holarctic and Fennoscandian, respectively. Due to the legacy of Pleistocene glaciations, endemic Fennoscandian species are problematic and it is thus concluded that there are probably no true endemic crane flies in this region. Finally, there are probably species living within Finnish borders that have hitherto remained unnoticed. Based on subjective assessment, the number of “true” (i.e. recorded + unknown species) species count of Finnish crane flies is at minimum 350.

The horse industry is in many ways still operating the same way as it did in the beginning of the 20th century. At the same time the role of the horse has changed dramatically, from a beast of burden to a top athlete, a production animal or a beloved pet. A racehorse or an equestrian sport horse is trained and taken care of like any other athlete, but unlike its human counterpart, it might end up on our plate. According to European and many other countries’ laws, a horse is a production animal. The medical data of a horse should be known if it is to be slaughtered, to ensure that the meat is safe for human consumption. Today this vital medical information should be noted in the horse’s passport, but this paperbased system is not reliable. If a horse gets sold, depending on the country’s laws, the medical records might not be transferred to the new owner, the horse’s passport might get lost etc. Thus the system is not fool proof. It is not only the horse owners who have to struggle with paperwork; veterinarians as well as other officials often use much time on redundant paperwork. The main research question of this thesis is if IS could be used to help the different stakeholders within the horse industry? Veterinarians in particular who travel to stables to treat horses cannot always take with them their computers, since the somewhat unsanitary environment is not suitable for a sensitive technological device. Currently there is no common medical database developed for horses, although such a database with a support system could help with many problems. These include vaccination and disease control, food-safety, as well as export and import problems. The main stakeholders within the horse industry, including equine veterinarians and horse owners, were studied to find out their daily routines and needs for a possible support system. The research showed that there are different aspects within the horse industry where IS could be used to support the stakeholders daily routines. Thus a support system including web and mobile accessibility for the main stakeholders is under development. Since veterinarians will be the main users of this support system, it is very important to make sure that they find it useful and beneficial in their daily work. To ensure a desired result, the research and development of the system has been done iteratively with the stakeholders following the Action Design Research methodology.

Ympäristönsuojelulain (86/2000) 19 §:n nojalla kunnilla voi olla ympäristönsuojelumääräykset. Määräysten antaminen on kunnille vapaaehtoista. Määräysten tulee olla ympäristönsuojelulain täytäntöönpanon kannalta tarpeellisia, kunnan paikallisista olosuhteista johtuvia kuntaa tai sen osaa koskevia yleisiä määräyksiä. Määräykset antaa kunnanvaltuusto. Ympäristönsuojelumääräyksillä on muuta lainsäädäntöä täydentävä, ei korvaava asema. Tämän työn tavoitteena oli laatia Kotkan kaupungille ehdotus kunnan ympäristönsuojelumääräyksiksi. Työn teoriaosassaon selvitetty kunnan ympäristönsuojelumääräysten oikeudelliset lähtökohdat ja suhde muuhun lainsäädäntöön. Tulososassa on selvitetty mitä toimintoja Kotkassa tulisi säännellä kunnan ympäristönsuojelumääräyksin. Työn toimeksiantajan kannalta oleellisimmat tulokset on esitetty työn liiteosassa. Ehdotuksen määräykset koskevat jätevesien käsittelyä, lumenkaatopaikkojen aiheuttamia ympäristöhaittoja, pölyn torjuntaa, tilapäisen melun torjuntaa, öljysäiliöiden tarkastamista ja käytöstä poistamista sekä hevosten pidon ympäristövaikutuksia. Ympäristönsuojelumääräysten voimaantulon myötä osa ympäristönsuojeluviranomaisen antamista suosituksista saa sitovan vaikutuksen. Ympäristönsuojelumääräykset osaltaan selventävät ympäristönsuojeluviranomaisen mahdollisuuksia puuttua eri toimintojen ympäristövaikutuksiin ennakolta.
