Total.porosity （TP）, determined by image anal.sis, pore type and pore size distribution were eval.ated on impregnated soil.bl.cks f.om an undisturbed Brazil.an sandy l.am soil.using a digital.portabl. optical.microscope. The f.ee sof.ware Image J （version 1.40g） was used f.r image anal.sis. Procedures f.r soil.image col.ection and anal.sis were presented. The image anal.sis al.owed the eval.ation of.pore sizes with diameters ranging f.om 20 to 〉 1 000 μm. The f.l.owing types of.pores were al.o obtained： rounded, el.ngated and intermediate. The resul.s M[owed the characterization of.the soil.as moderatel. porous （TP = 21.6%）. Rounded, intermediate and el.ngated pores were responsibl. f.r 11.6%, 31.7% and 56.7% of.TP.

Recent studies have documented decl.ning trends of.various groups of.f.0}wer-visiting insects, even common butterf.0} species. Causes of.these decl.nes are stil. uncl.ar but the l.ss of.habitat qual.ty across the wider countryside is thought to be a major f.ctor. Nectar suppl. constitutes one of.the main resources determining habitat qual.ty. Yet, data on changes in nectar abundance are l.cking. In this study, we provide the f.rst anal.sis of.changes in f.0}ral.nectar abundance on a national.scal. and l.nk these data to trends in butterf.0} species richness and abundance. We used transect data f.om the Dutch Butterf.0} Monitoring Scheme to compare two time periods： 1994-1995 and 2007-2008. The resul.s show that butterf.0} decl.ne can indeed be l.nked to a substantial.decl.ne in overal. f.0}wer abundance and specif.c nectar pl.nts, such as thistl.s. The decl.ne is as severe in reported f.0}wer general.sts as in f.0}wer special.sts. We suggest that eutrophication is a main cause of.the decl.ne of.nectar sources [Current Zool.gy 58 （3）： 384-391, 2012].
