  • Summary

    Clear scientific recommendations based on the best evidence available are essential in making decisions using all areas of applied science, including conservation. Unfortunately, ecological systems are enormously variable at all scales, and this variability drives uncertainty in predictions and recommendations. In this chapter different sources of variability are reviewed. It is crucial that sources of uncertainty are understood and tackled where possible. Ignoring uncertainty potentially leads to overconfident estimates of effectiveness, or biased outcomes if uncertainty is non-randomly distributed. Examples are given, and techniques for dealing with uncertainty are discussed, including new statistical and analytical techniques that can deal with uncertainties resulting from, for example, lack of information or missing data. The value of collating data across multiple sites or studies is also highlighted, and examples given of how this can help overcome the limitations of lack of information.

  • Lomatogonium gaurgopalii sp. nov., a new species of Gentianaceae from Sikkim Himalaya, is described and illustrated. It can be distinguished from its morphologically closest relative, Lomatogonium cherukurianum S.K.Dey & D.Maity, mainly by its robust habit, longer internodes, much larger creamy yellow flower and much larger floral parts; the presence of many hairs in an inverted semilunar arrangement behind the filament bases; and its larger, narrowly ovoid to narrowly ellipsoid ovary. Lomatogonium gaurgopalii is also unique in having pollen grains with striate-reticulate exine ornamentation without perforations.
