biomass production, fallow deer preference and species diversity
… areas, create shelter and forage, and also to increase the biological diversity. In this study I investigated how the plant composition in six different crop mixes used for game fields affected the biomass production, biomass consumption and biological diversity at the Koberg …
Carabidae) i hävdade strandnära gräsmarker :
Diversity of ground beetles (Col: Carabidae) in managed riparian grasslands. The carabid community in moist seminatural grasslands was studied at three different sites in mid-Sweden. Pitfall trapping was carried out during six weeks in spring and early summer 2003. Eight …
… was done to transform pollen percentage to tree species composition. Shannons diversity index was used to illustrate the changes we’ve studied. Three study sites cover the 20th century and shows higher levels in the diversity index the last century than at any time during the …
… difference was detected between the different treatments concerning diversity (Shannon diversity index: F3,25=1,39; P=0,27 and Simpson diversity index: F3,25=1,47; P=0,25), taxonomic richness (F3,25=1,74; P=0,19) nor density (F2,25=0.41; P=0,75) of the macroinvertebrate fauna …
What makes the Swedish wild boar reproduce more or less successfully?
… study was to test, on the county scale level, if landscape composition and diversity as well as people and hunter densities might be the reason for this variation. The first hypothesis was that a big proportion of forests and cropland would increase the rate of increase. The …
… No clear differences could be found in numbers of taxa and individuals, diversity index, pollution index or functional feeding groups between the part of the streams affected by erosion and the part of the streams, which had not been affected. This could be due to the fact that …
Sweden signed, in 1992, the Convention on Biological Diversity (CBD) and has thus assumed responsibility for the indigenous biodiversity. That also means that Sweden has a conservation responsibility for the Swedish Friesian (SLB) (SJV, 2007a). In a survey conducted by the Board …

… index that showed a difference between the different areas was Berger-Parker diversity index. The reason why there were no greater differences between the areas may be due to the fact that two years is too short to allow time for the benthos to re-colonize the restored area.
… The only index that showed a difference between areas was the Berger-Parker diversity index showing that the downstream reference stretch differed from the other two. None of the analyses showed that the restored area was different from the other two, probably due to too short a …
… data prevented further analysis of the impact of air pollution on the lichen diversity. In terms of the air quality indices, they did not result in the expected pattern of better air quality at a lower-polluting site since the results were influenced by the only minor …
Syftet med uppsatsen är att utvärdera två landskapsindex: ett formindex som beräknar formen för varje markanvändningsyta ( eng. "patch"); ett diversitetsindex, som beskriver de olika markanvändningarnas relativa utbredning. Formindexet beräknas på två olika sätt, beroende på om …
… that skunk work leaders&managers encounter when promoting new ideas. The diversity of the barriers led to the clustering of nine categories compiled from the skunk leaders personal interviews. The nine categories are assumptions, change, communication, competences, culture …
… created by Hofstede (2005) helps to explain some of the dissimilarities. The diversity in short-term thinking, masculinity and individualism in the two countries may contribute to an explanation of what have affected the development of the ethical clothing market.
