seasonal activity and spatial distribution of eoteranychus frosti mcgregor, tydeus longisetosus (elbagouy and momen) and zetzellia mali ewing were studied during 9th july to 22th october 2006 in an unsprayed apple orchard, maragheh region, northwest of iran. also the density dependence interaction between preys and predator was assessed. to estimate the spatial distribution pattern of these spe...

bionomics of aphis gossypii glover and its predators coccinella septempunctata l. and hippodamia variegata goeze were studied in varamin (tehran province) during 11th may to 5th october 2006 on eggplant crop, with the interaction (density dependence) between the aphid and either of the predators determined. the reliable sample size (number of leaves) with a maximum variation of 6.73% was about ...

Researchers (e.g., M. B. Brewer & W. Gardner, 1996; H. C. Triandis, D. K. S. Chan, D. P. S. Bhawuk, S. Iwao, & J. P. B. Sinha, 1995) have suggested expansion of the standard model of individualism-collectivism to include people's close personal relationships in addition to their identification with in-groups. There has been considerable discussion of the hypothesis that women are more collectiv...

Patchiness of above-ground vegetation, such as that in semi-arid grasslands and shrublands, can pose problems in sampling plant cover, biomass and productivity. We present a method of measuring above-ground plant biomass and production that can be applied consistently among vegetation types and that generates seasonal, spatially-explicit results. Results from 15 sites within the Jornada Basin (...

Patchiness plays a fundamental role in phytoplankton ecology by dictating the rate at which individual cells encounter each other and their predators. The distribution of motile phytoplankton species is often considerably more patchy than that of non-motile species at submetre length scales, yet the mechanism generating this patchiness has remained unknown. Here we show that strong patchiness a...

100-GHz and 300-GHz coherent radio-over-fiber transmission using optical frequency comb source Author(s): Atsushi Kanno; Toshiaki Kuri; Iwao Hosako; Tetsuya Kawanishi; Yoshihiro Yasumura; Yuki Yoshida; Ken-ichi Kitayama Millimeter-wave and sub-millimeter-wave radio-over-fiber (RoF) technology with digital-signal-processing aided coherent detection can be a promising candidate for high-speed rad...

Clonal growth allows plants to spread horizontally and to experience different levels of resources. If ramets remain physiologically integrated, clonal plants can reciprocally translocate resources between ramets in heterogeneous environments. But little is known about the interaction between benefits of clonal integration and patterns of resource heterogeneity in different patches, i.e., coinc...
