Completing Linnaeus's inventory of the Swedish insect fauna: Only 5,000 species left?

Despite more than 250 years of taxonomic research, we still have only a vague idea about the true size and composition of the faunas and floras of the planet. Many biodiversity inventories provide limited insight because they focus on a small taxonomic subsample or a tiny geographic area. Here, we report on the size and composition of the Swedish insect fauna, thought to represent roughly half of the diversity of multicellular life in one of the largest European countries. Our results are based on more than a decade of data from the Swedish Taxonomy Initiative and its massive inventory of the country's insect fauna, the Swedish Malaise Trap Project The fauna is considered one of the best known in the world, but the initiative has nevertheless revealed a surprising amount of hidden diversity: more than 3,000 new species (301 new to science) have been documented so far. Here, we use three independent methods to analyze the true size and composition of the fauna at the family or subfamily level: (1) assessments by experts who have been working on the most poorly known groups in the fauna; (2) estimates based on the proportion of new species discovered in the Malaise trap inventory; and (3) extrapolations based on species abundance and incidence data from the inventory. For the last method, we develop a new estimator, the combined non-parametric estimator, which we show is less sensitive to poor coverage of the species pool than other popular estimators. The three methods converge on similar estimates of the size and composition of the fauna, suggesting that it comprises around 33,000 species. Of those, 8,600 (26%) were unknown at the start of the inventory and 5,000 (15%) still await discovery. We analyze the taxonomic and ecological composition of the estimated fauna, and show that most of the new species belong to Hymenoptera and Diptera groups that are decomposers or parasitoids. Thus, current knowledge of the Swedish insect fauna is strongly biased taxonomically and ecologically, and we show that similar but even stronger biases have distorted our understanding of the fauna in the past. We analyze latitudinal gradients in the size and composition of known European insect faunas and show that several of the patterns contradict the Swedish data, presumably due to similar knowledge biases. Addressing these biases is critical in understanding insect biomes and the ecosystem services they provide. Our results emphasize the need to broaden the taxonomic scope of current insect monitoring efforts, a task that is all the more urgent as recent studies indicate a possible worldwide decline in insect faunas

Venture Capital : What factors lie at the basis for Venture Capital investment decisions?

Introduction: Venture capital investment process is complex and different firms vary greatly in their investment practices. This has resulted in authors given several different factors that could be imperative for venture firms investment decisions. There is thus no consensus in the field of venture investing. Purpose: The purpose of this thesis is to list which factors are important for venture capital firms investment decisions in start-up firms. Method: The authors conducted structured phone interviews with seven venture capital firms in Sweden. Conclusion: The authors found the following factors to be important for venture firms investment decisions in start-up firms; Busienss plans that demonstrated the thinkings of the entrepreneur, communicate ideas, visions, product, market, competition, growth potential as well as the planned intentions with the recived funds. They also desired realistic, concreate, simple plans that explained the implementation process of the start-up firm. The second factor that was important was markets where large markets, market growth, market share, market entry and global markets were mentioned. The third factor of importance was product, in which uniqueness, simplicity, patents and time-to-market were listed. Management was the fourth factor of importance, in which sensibility, competence, technical skills, entrepreurial spirit, attitude, humbelness, determination, openness, drive, chemistry and confidence were included. The fifth factor of importamce financial embraced ROI, economioes of scale, valuation and the size of the investment. The last two important factors that the authors found to be important for the venture firms in the study were location and industry
