1.1 Background of study
Diversity concept can be defined by refers to variety of living organisms in a particular area (Statistica, 2013). Since diversity involves many living organisms and include different species, thus it may be very complex. There are two significant divisions within the scope of diversity which are species diversity and habitat diversity (Mumby, 2001). Both represent structural complexity of environments. In order to reduce complexity of ecological system, ecological diversity concept can be used, through diversity indices. Generally, for the measuring species diversity common way that can be used are count the species richness and species abundance. These two methods include the information …show more content…

In general, species diversity is a measure of the number ofcomponent species and their abundance at a defined point in space and time (Tews et al., 2004). The presence of different species in community arise the difficulties to assign the individual species in particular size. In order to reduce the problem arising, diversity measure will be applied to measure species diversity for a community. Diversity measures may lead different the ordering in a community into ecological organization Even species diversity is related to each other but the functional role are equally different According to Boulangeat et al.(2012) The difference of functional role among species can be identified using diversity measures. Basically there are two different approach involve in diversity measures such as number of species (species richness) and the relative abundance of individuals within each species (species abundance).Combination information between both measures are used in method using mathematical indices or also known as diversity indices (Kreb, …show more content…

In addition zygoptera was good indicator of disturbance to indigenous riparian vegetation and sensitive by disturbance create by commercial forestry. However, in this study the lack number of Anisptera compared to Zygoptera might due to Sekayu Forest unable to support suitable habitats for most Anisoptera was basically present at larger ponds with floating macrophytes and chasing each other on sunny days (Oppel,
