This is a electronic series beginning in 2005, which replaces the earlier series NINA commissioned reports and NINA project reports. This will be NINA's usual form of reporting completed research, monitoring or review work to clients. In addition, the series will include much of the institute's other reporting, for example from seminars and conferences, results of internal research and review work and literature studies, etc. NINA report may also be issued in a second language where appropriate.
NINA Special Report (NINA Temahefte)As the name suggests, special reports deal with special subjects. Special reports are produced as required and the series ranges widely: from systematic identification keys to information on important problem areas in society. NINA special reports are usually given a popular scientific form with more weight on illustrations than a NINA report.
NINA Factsheet (NINA Fakta)Factsheets have as their goal to make NINA's research results quickly and easily accessible to the general public. The are sent to the press, civil society organisations, nature management at all levels, politicians, and other special interests. Fact sheets give a short presentation of some of our most important research themes.
Other publishingIn addition to reporting in NINA's own series, the institute's employees publish a large proportion of their scientific results in international journals, popular science books and magazines. Freshwater fish were collected mainly by electrofishing in 27 localities in rivers and streams within the Area de Conservacion Guanacaste in northwestern Costa Rica, in June 1998 (rainy season), February 1999 and March 2001 (dry season). The fish were identified and analyzed for macroparasites. Fourteen localities were in rivers draining to the Atlantic, and 13 draining to the Pacific. On the Pacific slope, three localities were seasonal streams with small catchment areas. Five localities lacked fish, probably due to effluents from volcanic areas. A total of 36 fish species were recorded, including one new to science; Poecilopsis santaelenae. The most commonly occurring species were the catfish Rhamdia rogersi (11 sites), the cichlid Astatheros alfari (10 sites), and the guppy Poecilia gillii (9 sites). A total of 25 fish species were recorded on the Pacific slope, and 26 species on the Atlantic slope. On the Pacific slope, sampling sites were at altitudes from 8 to 880 m a.s.l.; on the Atlantic slope from 205 to 675 m a.s.l. On both slopes the number of species per site decreased with increasing altitude. Fish communities at lower altitudes included species feeding on detritus and plant material as well as species feeding on invertebrates and fish. At higher altitudes, species feeding on invertebrates became increasingly dominant. At the uppermost sites, the only recorded fish species were invertebrate feeders.
Norwegian Institute for Nature ResearchA total of 50 parasite taxa were recorded by necropsy and visual inspection of the fish material. Both prevalence and abundance of parasites w...
