“…From these results, we conclude that the indicator species of these groups can be categorized as open-specific (group 2), forest-specific (group 4), and unspecific (eurytopic) species (group 1). This classification agreed with the ecological characteristics of each indicator species and previous research 14,42 . The NMDS ordination shows that the surroundings of the ponds in groups 5 and 6 were characterized by small vegetation coverage, open areas, and long revetment lengths.…”

To clarify the effect of environmental factors on odonate assemblages in rural reservoir ponds, we surveyed the odonate adults (Zygoptera and Anisoptera) in 70 study ponds in Ibaraki Prefecture, Japan, during three sampling periods in 2005. Cluster analysis, indicator species analysis (INSPAN), and non-metric multidimensional scaling (NMDS) were used in combination to determine the relationship between odonate assemblages and environmental variables, i.e., biotic, physicochemical, and regional variables (the types of land use surrounding the ponds). A total of 41 odonate species were recorded in the study ponds, and 24 of them, excluding rare species, were used for each analysis. The study ponds were classified into six groups, and significant indicator species were selected from four of these groups. Examination of the correlation between each environmental variable and NMDS axes 1 and 2 revealed the profound effects of the presence of forest, paddy field, or open area around the ponds on the indicator species composition of each group. It was also revealed that the aquatic vegetation and forests around the ponds provide desirable conditions for the odonates and, in contrast, concrete revetment has a detrimental effect. These results suggest that the recent decrease of forests around ponds and the reconstruction with concrete revetment will have a negative effect on the odonate assemblages in ponds.

“…However, these studies have investigated either a single or several environmental factors. Only a few comprehensive analyses of these factors have been undertaken 5,14,32,42 . The objectives of our study were to clarify the environmental characteristics that influence pond odonate assemblages.…”

“…The following studies have been already published: biodiversity of Odonata species (Morita et al 2001;Ichinose and Morita 2002;Yamano et al 2002), vegetation communities on levees in paddy fields and ponds (Matsumura 2002;Iwasaki et al 2003;Mitsui et al 2003), biodiversity of diatom communities in ponds (Katoh et al 2004), and water quality of ponds (Ichinose and Kataoka 2003). Herein, we analyze land-use changes in the agricultural landscape from 1963 to 2000.…”
