SUMMARYBecause of their isolation, biotic communities of urban green spaces are expected to be similar to those of oceanic islands. This should be particularly true for insects, which represent an important component of urban faunas. The equilibrium theory of island biogeography (ETIB) allows for the formulation of some hypotheses regarding the influence of the geographical characteristics of green spaces on insect species richness and extinction risk. Based on island biogeography principles, we present eight predictions on how green space characteristics should influence insect species richness and loss. We analysed the current literature in order to determine which predictions were supported and which were not. We found that many studies gave outcomes that support ETIB predictions about the effects of area and isolation of green spaces; we found no strong support for predictions about shape and extent of native habitat in the literature that we reviewed. Most of the available studies dealt with patterns in species richness, whereas insect species loss has been rarely investigated. Future developments in the application of island biogeography principles to urban insect conservation should address temporal trends in species persistence and the analysis of species co-occurrence and nestedness.

Abstract. Withaningsih S, Parikesit, Rabbany MB. 2019. Correlation between some landscape metrics and insect species richness in coffee agroforests in Pangalengan Subdistrict, Bandung District, West Java, Indonesia. Biodiversitas 20: 3075-3085. The insect community provides valuable ecosystem services and can help maintain ecosystem integrity in human-altered landscapes such as coffee agroforests. The aim of this study was to assess the landscape characteristics of coffee agroforests in the Pangalengan Subdistrict and analyze how those characteristics influence the insect communities. Landscape metric approaches were examined to quantify landscape characteristics and the results analyzed using correspondence analysis to determine variation among samples, and simple linear regression testing was used to determine the influence of those landscape characteristics on the insect community. Seventeen sample locations varied in characteristics based on the proportion of the land cover classes, and landscape characteristics determined the number of insect species. The number of insect species showed strong negative correlation with landscape heterogeneity (R2=0.456) and number of patches (R2=0.514) and a weak positive response to the proportion of natural forest remaining (R2=0.150). Number of insect species showed a strong negative correlation to landscape heterogeneity, number of patches, and number of natural forest remaining simultaneously (R2=0.514).
