“…endemic and/or native) arthropod community. These results are in agreement with other studies in the Azores (Borges and Wunderlich 2008;Cardoso et al 2009) and elsewhere (Driscoll 2005;Schweiger et al 2005;Jana et al 2006;Rainio and Niemelä 2006;Acevedo and Restrepo 2008;Schmidt et al 2008), that have demonstrated negative effects of such land-use change for several taxa.…”

We study how endemic, native and introduced arthropod species richness, abundance, diversity and community composition vary between four different habitat types (native forest, exotic forest of Cryptomeria japonica, semi-natural pasture and intensive pasture) and how arthropod richness and abundance change with increasing distance from the native forest in adjacent habitat types in Santa Maria Island, the Azores. Arthropods were sampled in four 150 m long transects in each habitat type. Arthropods were identified to species level and classified as Azorean endemic, single-island endemic (SIE), native, or introduced. The native forest had the highest values for species richness of Azorean endemics, SIEs and natives; and also had highest values of Azorean endemic diversity (Fisher's alpha). In contrast, the intensive pasture had the lowest values for endemic and native species richness and diversity, but the highest values of total arthropod abundance and introduced species richness and diversity. Arthropod community composition was significantly different between the four habitat types. In the semi-natural pasture, the number of SIE species decreased with increasing distance from the native forest, and in the exotic forest the abundance of both Azorean endemics and SIEs decreased with increasing distance from the native forest. There is a gradient of decreasing arthropod richness and abundance from the native forest to the intensive pasture. Although this study demonstrates the important role of the native forest in arthropod conservation in the Azores, it also shows that unmanaged exotic forests have provided alternative habitat suitable for some native species of forest specialist arthropods, particularly saproxylic beetles.

“…For the present work, eight study sites were selected from the eastern and southern parts of Midnapur District (Jana et al 2005(Jana et al , 2006. This district covers an area of 14,081 km 2 and has a total human population of 8,349,890 (Census Report 1991).…”

“…The locations of the study sites are shown in Fig. 1 of Jana et al (2006). The climate of this part of the country is monsoonal, with an average rainfall of 1,470 mm and an annual range of temperatures of 9-43°C.…”

“…Byproducts of industries can adversely affect biota and ecosystems (Moser et al 1991;Jana et al 2006). Quantitatively determining biodiversity is likely to provide tools for ranking areas by species richness to optimize conservation effort (Araujo 1999;Wessels et al 2000).…”

“…A comparison of insects and their host plants in industrial and nonindustrial areas was performed by Jana et al (2005), who not only highlighted a new aspect of the diversity of insect fauna (the baseline consumers of plants-producers), but also measured the quality of the environment with a view to exploring the bioindicators and insect-plant dependencies in both industrial and nonindustrial zones. Jana et al (2006) studied the diversity of five insect orders-Hemiptera, Orthoptera, aculeate Hymenoptera, Lepidoptera, and Coleoptera-in an industrial region of Haldia (West Bengal, India) and in a nonindustrial area in the same district; the study sites encompassed an aerial distance of 40 km, and shared similar physiographic, vegetative, climatic conditions, and spatial landscapes. Based on binary data, they showed that the diversity of hemipteran species was 40% lower and the diversity of both lepidopteran and orthopteran species was 36.8% lower in the industrial zone.…”

This paper compares the species richnesses, Bray-Curtis similarities, species diversities, evennesses, and the results of various analyses (multivariate, logarithmic series, and lognormal distribution analyses) of insects from four orders (viz., Hemiptera, Orthoptera, aculeate Hymenoptera, and Coleoptera) inhabiting a medicinal plant, Calotropis procera among eight sites within industrial and nonindustrial zones in the Purba Medinipur district (erstwhile Midnapore), West Bengal, India. Both cluster analysis and principal component analysis indicate an effect of industrialization on the diversity of the four insect orders. The species community at each site exhibits an almost pure lognormal distribution. Bootstrap estimation of species diversity also points to the effect of industrialization. A comparison of the values of x and N/S of the logarithmic series indicates a typical relationship between the species community and its diversity. The number of unique species among the eight study sites is 6 according to jackknife estimation. Beta-diversity analysis of the samples shows the impact of industrialization on the abundances and species richness of the insects. Altogether, 16 types of analytical procedure are applied for this purpose, and their suitabilities for this kind of data set are assessed. Disturbance, probably due to industrial emissions, has changed the compositions and structures of the insect communities out to a distance of at least 6 km from the core industrial area.
